@@raven4k998 Gladly! There might be a few based on the Z80 or the 6502 I can certainly tinker with. And while I'm at it, learn punctuation and spelling. Then maybe you'd be taken seriously.
I remember working in a "mom&pop" computer shop in the late 90's and we got several fake chips, some of them from reputable distributors that got the short end of the stick ordering parts. In the end I got so proficient at spotting the fakes I could tell them just by glancing at the reflection of the light on the surface of the chip: usually the fakes were a bit shinier and usually had like a rectangular extra-shiny spot around where the fake engraving would occur - my guess is that they used some kind of fill-and-smooth technique to hide the old engraving. Thing is, with active cooling these processors were easily overclocked up to 200mhz without losing stability (yes; back then you could get a 100% boost by overclocking a processor!) and by the mid-90's Intel binning was mostly about filling niches, as most of the processors where greatly underrated (so, most pentiums were capable of operating @150mhz, but intel needed lower parts because there was demand for the cheaper processors) so probably the clients would have not noticed if we installed these parts.
Selling overclocked chips must have been fairly rampant back then. I believe this was the reason Intel locked the CPU multipliers starting on the Slot 1 PII's.
to me the fake cpu market of the early 486 and 6x86 era is some of the most interesting things.... love that you're covering some of it:)..... found it funny that I seen one of the major retro youtubers reviewing a mobo that had a known fake chipset but they didn't realize it till I point it out:D and showed them articles relating to it:'D
Going from 120 MHz to 133 MHz is a 10.8% increase. It's like having a 1 GHz vs 1.108 GHz or 2 GHz vs 2.216 GHz. Also, nothing prevented us from overclocking these chips. I had a 200 MHz Pentium MMX which I pushed to 225 MHz. At 250 MHz, it was a little unstable.
They were probably pretty safe by overclocking them just one iteration (ie 60mhz bus to 66) Since Intel has always been pretty conservative when binning their silicon for chips, most of them probably worked OK for the life of the machine. That being said, it says something about Intel's pricing structure.
At that time, I used to overclock my CPU. Pentium 120 running at 133, Pentium 150 running at 166, and lastly a Pentium 200 MMX running at 250 MHz with a 100 MHz system clock instead of 66. This last one was faster than PII-233 when fpu wasn't involved !
The Chinese used to do this with CD-ROM's too, in 1998 I got a CD-ROM from a well known supplier that came in a box that said 16x, the sticker on the drive said 16x and the face-plate had 16x silk screened onto the front but I was using Linux and it detected it as an 8x, so I did some testing and realised its an 8x drive and spoke to the supplier and they did their own tests and realised they had been conned by a supplier and had to recall all the cd-rom drives and exchange them for real 16x ones. If I had been using windows I wouldn't have known the difference.
I onc bought an i5 laptop, it was so fricking slow on Windows, when installing Linux discovered it was a Celeron 3350 and everything saying i5 was actually a registry hack.
Didn't know about that the Chinese have made weird laptop to desktop abominations already in the 90s. Linus tested a Chinese laptop Haswell CPU modified to a LGA1150 package.
the coating must certainly have hurt thermal performance, i wonder how much of the reduction in reliability was due to worse cooling rather than the overclocking itself
pentiums could run for ages even of the fan died, as long as its heatsink was still on it ran fine, so I dont think it would have made much difference back in those days.
Interesting. This is like older version of the fake capacity flash memory devices from China. But as I understand at least these CPUs delivered, unlike fake flash drives. Think of them as factory overclocked CPU
I imagine this is probably why modern PCs can automatically set clock speeds of CPUs, and/or why modern CPUs have ID strings. I can imagine getting tricked into getting one of those counterfeit CPUs back then, and wondering why the custom-built PC had so many issues. I can also imagine there being adverts about "genuine Intel processors".
I got burned back in the day. I found a guy that had a 133MHz Pentium, brought it home and it wouldn't run right. I set the jumpers to 120 and it ran fine for a long time. I paid 150 for it. Must have been a good deal to young me. I was happy to have a P120 still.
It sounds like it's not a multiplier OC but an FSB overclock. I think earlier CPUs get a huge jump in performance due to the FSB speed improvement. If you were a home user that couldn't A/B CPUs, it made detecting this much harder.
Romania was under embargo until 2004 from importing any Intel chips above 1ghz, namely because a state owned company made lots of Intel clones starting from the 80s. I know people claim we even did Pentium 1 to 3 clones. I would totally want to hear your opinion on those!

Wow, all those bonding wires in the X-ray image! Now it makes sense that those ceramic CPUs have such a high scrap value. There's probably a few grams of gold in there.
I didn't realise Intel had been using those S - - - - codes on their processors and chipsets for so long. That is an SY022 and one of my PCs has an SREJP.
I found already some where the ceramic is thinner than usual. I think this was an advanced way of relabeling. They sand the ceramic down and engraved again with a laser the black markings and reprinted the white stuff. The ceramic surface looks different under the microscope and also the used font is obviously different. i am still researching on that topic before I‘ll make an update video on that.

Do you have any WinChip CPU? I know, they are not rare but at least interesting. I'm just a little bit curious about what they exactly are. If they are clones or something else. I have one which is WinChip 200MHz.
Centaur winchip. No its not a copy of intel pentium design.its compatible. It implements a lot of instructions as multiple. Risc instructions ... Slower..but the core instructions were implemented as one risc instruction. Anyway due to smaller cache, and lower transistor count,they got mmx performance at 5 volts...So it was sold as an upgrade to fit in old 5 volt motherboards. Socket 7 had various voltages... 5 , 3.3 and the adjustable voltage thing started .. such as 2.8 2.9 3.0 ...
Also there where motherboards then with fake cache chips on it. It where empty dil packages and the bios was modified to report a number of cache present. Those chips where also pretty expensive then.
I remember hearing about a scam where vendors would overclock lower frequency chips but I didn't know they were going through the trouble of trying to reprint the model number on top of the chip. I just assumed that they just overclocked the final consumer PC. Most people never remove the cooling fan and wouldn't think to check to see what is printed on the chip to make sure they weren't swindled. Of course I know mine was original because I was too cheap to buy anything faster than the 75mhz model. Moores law made buying the fastest chip on the market a bad investment back then anyway.
I also saw this with CPU & motherboard combos. The seller would put a warranty sticker over the side of the heatsink, CPU, and socket. The only way you could see if the CPU was genuine is to remove the heatsink. If you tried to get a return/refund from the seller because you got scammed, they would refuse and say you voided the warranty. Very shady.
I can confirm , that this practice of REMARKING CPUs was still present up to 2004, cause i was able to buy them trough reputable distributor with ease. They were marked as such , but unfortunately AMDs ones ended up with short end of the stick , cause of the open die and cracking , 4 out of 10 were dead or unable to work. They were usually sold in trays , once they started going with boxed coolers situation changed . However i remember well my P3 Celereon i had in my PC clearly remarked as a 900 MHZ CPU , but it was a 600 MHz one . However i was able to run it on 1200 MHz without any issues for more over than a year , and as far as i remember it went well pass that with 142mhz bus increase but i kept it at 133 and it worked like a charm . So Intel CPUs were well capable of even 2x+ speed they were rated , not all of them ofc.
Im sorry but im calling BS on you overclocking a 600mhz Celeron to 1200mhz without LN2 or some other refrigerant type cooling setup. I have seen a Celeron overclock to 8.4ghz but it was with liquid nitrogen. I can overclock my current 10th gen intel chip 1300mhz but I am using liquid cooling and I have my chip undervolted.
@@ryanmalin I'm not joking or over selling it . It is God honest truth. My personal CPU, not cherry picked from a bin of CPUs. It was 100% stable on 1200 MHz on normal CPU cooler. I don't remember the temps of it but it was working without any issues even in my converted attic room at the time with room temps over 35 C without any issues . I sold off the mainboard ( i dont recall what mainboard was at the time ) and CPU as 1200 Mhz one i had 1 GB of ram in it ( 4x256 MB) and Intel i740 AGP graphics - i remember that well cause it was the worst graphic that i ever had. Thing is CPU's back 20+ years ago were built much differently , with large overhead and sold to scale down the line, thats why remarking CPUs was such a huge business . Nowadays its totally different , You need like stupid refrigeration to get high clocks, and that is just to see how much you can pull out of it - not for everyday use.
I never cease to be amazed at how far some individuals will go to cheat, steal or misrepresent themselves and or the items they are selling. I guess in the past it was a bit harder for a shady salesman selling crap as it didn't take long for the word to spread to avoid them and if you were unfortunate enough to make contact with them, go home at once and take a long shower.
I remember setting Pentium 100 to 133 and it worked perfectly for at least 1 year before I got AMD K6-2. That's what I call overclocking, +33% for free wintout any investment.
I had a 200 MHz Pentium MMX which I pushed to 225 MHz. At 250 MHz, it was a little unstable. My firs AMD was the Athlon Barton core. Athlon XP 2800+. I think it ran at 2400 MHz or was it 2075 MHz. It had 512 KB L2 cache and that is why I bought it.
yep most of the boost was just in the FSB.. what's funny is i used to do this all the time.. i would get a cheaper CPU and over clock the piss out of it.. some times i would order 3 CPU;s see what one was faster and return the other 2
Multiplier lock wasn't used by intel until the Pentium II line. The original Pentium CPUs could be set to whatever clock and multiplier the motherboard supported and the cpu and memory ran stable.
Try the 300Mhz Tillamook on a PCChips M577 or M537. I tested the 266mhz on these, successfully. (Though i had to modifiy the CPU to enable the L2 Cache onboard which is switched off when you put the stock CPU into the socket) Another board i tested successfully was the FIC VA 503+. They were letting me overclock it to 400mhz stable at 2.2/2.3v Vvore. At a multiplier of 4.0x (FSB set to 100mhz). Would love to see the results with the 300mhz version, where you probably need a 4.5x Multiplier for at 66Mhz.
I just bought the Pentium 100 gold CPU from the link you provided, seller accepted my offer of $65.95 from their asking price of $81.27. Still looking for that 300 MHz MMX socket 7! Thanks again for the great content!
i can't believe it, i have 2 Pentium SL24R (166mhz). One of them gave me that strange colour scrubbing it with a bit of WD40. After a close look, i can barely see, under the new laser engraving that it was a SY022 133MHZ. Even the Intel Pentium logo was repainted. The other Pentium gave me no issues when scrubbing it but the engraving looks pretty much fake. BTW i have no idea if they're unstable or not, cause the motherboards are dead...
@@CPUGalaxy this one somehow managed to find it's way to Argentina..i found those in old office pc's that my grandfather had.. It's nice to know that they're collectible, it means that im gonna have it forever!
just a little update. I scrubbed all the "paint" on the surface of one of those fake Pentiums. Supposedly it was a SL24R, L6270129, but after all, it was a SY022 L7221064. So it means that it was manufactured in calendar week 22, 1997. Ok, everything seems normal BUT, in the rear it doesn't say i133 (like all the '96 and above), it says IPP. So whats the deal? xD
@@flyguille Internal hidden registers only held a model and step number, only later did Intel also have the clock registers being adjustable, and not set by links, and also readable. The original binning allowed processors that were marginal at full speed to be sold as cheaper units, as they were reliable at the lower clock speed, or were below the thermal envelope. Later on in the product lifetime the yield improved to the point that they were simply taking the full speed chips and derating them to fill the sales orders for the low speed devices. Otherwise the full spec devices, so they were easy to overclock as you simply took them back to rating and could go further as well.
i have a Pentium 133 that has the A80502-133 instead of A80502133. and a Pentium 75 that is like A8050275, without a dash before 75. some unique looking CPUs.
OE relabeled microchips aren't unusual, at least they weren't in the '90s-'00s. Sonnet Technologies had a write-up for some of their old Mac CPU upgrades where such chips are used, explaining that often these chips were originally labeled for a specific customer order that was later cancelled (for example: customer needs 3000 400MHz chips where these parts regularly qualify from 400-500MHz, so the OE will just certify the whole production lot as 400MHz to satisfy the order), but since the chips were actually capable of running at different (often faster) speeds, they were requalified, relabeled, and resold.
i remember working on a old pentium like that the coating came off with the thermal and heat sync i nver thought much about but it may have been on of these fakes lol
This made me check my collection... I only have early ones with iPP on the back, so they could be fake. And I just realized, that I have one that is an golden ES.
Tillamook's a pretty decent little town. Has a old WWII-era Navy base that got converted into a aviation museum with some nice specimen including a Aero-Spacelines Mini Guppy. The silage smell gets to be a bit much, though.

I can confirm , that this practice of REMARKING CPUs was still present up to 2004, cause i was able to buy them trough reputable distributor with ease. They were marked as such , but unfortunately AMDs ones ended up with short end of the stick , cause of the open die and cracking , 4 out of 10 were dead or unable to work. They were usually sold in trays , once they started going with boxed coolers situation changed .
However i remember well my P3 Celereon i had in my PC clearly remarked as a 900 MHZ CPU , but it was a 600 MHz one . However i was able to run it on 1200 MHz without any issues for more over than a year , and as far as i remember it went well pass that with 142mhz bus increase but i kept it at 133 and it worked like a charm . So Intel CPUs were well capable of even 2x+ speed they were rated , not all of them ofc.
Im sorry but im calling BS on you overclocking a 600mhz Celeron to 1200mhz without LN2 or some other refrigerant type cooling setup. I have seen a Celeron overclock to 8.4ghz but it was with liquid nitrogen. I can overclock my current 10th gen intel chip 1300mhz but I am using liquid cooling and I have my chip undervolted.
@@ryanmalin I'm not joking or over selling it . It is God honest truth. My personal CPU, not cherry picked from a bin of CPUs. It was 100% stable on 1200 MHz on normal CPU cooler. I don't remember the temps of it but it was working without any issues even in my converted attic room at the time with room temps over 35 C without any issues .
I sold off the mainboard ( i dont recall what mainboard was at the time ) and CPU as 1200 Mhz one i had 1 GB of ram in it ( 4x256 MB) and Intel i740 AGP graphics - i remember that well cause it was the worst graphic that i ever had.
Thing is CPU's back 20+ years ago were built much differently , with large overhead and sold to scale down the line, thats why remarking CPUs was such a huge business . Nowadays its totally different , You need like stupid refrigeration to get high clocks, and that is just to see how much you can pull out of it - not for everyday use.
I never cease to be amazed at how far some individuals will go to cheat, steal or misrepresent themselves and or the items they are selling. I guess in the past it was a bit harder for a shady salesman selling crap as it didn't take long for the word to spread to avoid them and if you were unfortunate enough to make contact with them, go home at once and take a long shower.
I remember setting Pentium 100 to 133 and it worked perfectly for at least 1 year before I got AMD K6-2. That's what I call overclocking, +33% for free wintout any investment.
I had a 200 MHz Pentium MMX which I pushed to 225 MHz. At 250 MHz, it was a little unstable.
My firs AMD was the Athlon Barton core. Athlon XP 2800+. I think it ran at 2400 MHz or was it 2075 MHz. It had 512 KB L2 cache and that is why I bought it.
And they're still doing the same thing now, but to NAND flash and DRAM chips. NEVER buy knock-off brand drives.
This was fascinating. Respect!
Is there a way to identify a fake Pentium chip non-destructively?
13 MHz more, but the bus ran at 66 vs 60. Quite a difference there.
yep most of the boost was just in the FSB.. what's funny is i used to do this all the time.. i would get a cheaper CPU and over clock the piss out of it..
some times i would order 3 CPU;s see what one was faster and return the other 2
OMG !... I could have been fallen into one of these fakes since I couldn't believe it is forged that good ....
Where did you get the C4004 fake? I'd be interested in that
Looks like they capped a mobile processor but how do they change the internal clock multiplier?
Multiplier lock wasn't used by intel until the Pentium II line. The original Pentium CPUs could be set to whatever clock and multiplier the motherboard supported and the cpu and memory ran stable.
I had bought a counterfeit Cyrix MII 333, unfortunately.
Oh yeah, I remember the rebadging back in the day...Cyrix CPU’s especially
I just scratched off a 100 Mhz marked one to find a 75 Mhz hidden under the paint
yeah i thought they looked to dark, i do wonder how many fakes i missed in computer fairs back in the day.
Appreciate your efforts 🙏😇 🎇
Thank you! 🙏🏻
Take of the golden plate of the MMX...i think they just glued it on!
Try the 300Mhz Tillamook on a PCChips M577 or M537. I tested the 266mhz on these, successfully. (Though i had to modifiy the CPU to enable the L2 Cache onboard which is switched off when you put the stock CPU into the socket) Another board i tested successfully was the FIC VA 503+. They were letting me overclock it to 400mhz stable at 2.2/2.3v Vvore. At a multiplier of 4.0x (FSB set to 100mhz). Would love to see the results with the 300mhz version, where you probably need a 4.5x Multiplier for at 66Mhz.
These are genuine CPUs then. Just packaging are faked.
TDP of 600w but should it be for a 9121 and not a 9221?
haha. oh damn.. did not recognized this mistake until now. Thank you! Of course I meant the 9121. 🤦🏻♂️
This makes me want to go and check my Intel 166mhz cpu. Maybe I am rich!
back in the days i had a 100mhz pentium that ran without any issues at 150mhz, good old times
I just bought the Pentium 100 gold CPU from the link you provided, seller accepted my offer of $65.95 from their asking price of $81.27. Still looking for that 300 MHz MMX socket 7! Thanks again for the great content!
i can't believe it, i have 2 Pentium SL24R (166mhz). One of them gave me that strange colour scrubbing it with a bit of WD40. After a close look, i can barely see, under the new laser engraving that it was a SY022 133MHZ. Even the Intel Pentium logo was repainted.
The other Pentium gave me no issues when scrubbing it but the engraving looks pretty much fake.
BTW i have no idea if they're unstable or not, cause the motherboards are dead...
Thanks for your comment. Interesting to see how many of those pentiums were around. Good that you found one. Nowadays they are collectible. 😉
@@CPUGalaxy this one somehow managed to find it's way to Argentina..i found those in old office pc's that my grandfather had.. It's nice to know that they're collectible, it means that im gonna have it forever!
just a little update. I scrubbed all the "paint" on the surface of one of those fake Pentiums.
Supposedly it was a SL24R, L6270129, but after all, it was a SY022 L7221064.
So it means that it was manufactured in calendar week 22, 1997.
Ok, everything seems normal BUT, in the rear it doesn't say i133 (like all the '96 and above), it says IPP. So whats the deal? xD
This video is like one of those finger puppet shows but without finger puppets....
I Cringe every time you drop a CPU.
yeah, this happens always when i specially take care that it would not happen 😅
Those fake ones are so unstable, cannot handle..
at that time there wasn't something like CPU model ID? that tells what is the real model by software?
no. only the cpu family code. clock rate was depending on the quality of the silicon die after production.
@@CPUGalaxy wasn't that deducted by software looking for which sets of opcodes was available?, or it has a specific opcode for lookup the family?
@@flyguille Internal hidden registers only held a model and step number, only later did Intel also have the clock registers being adjustable, and not set by links, and also readable. The original binning allowed processors that were marginal at full speed to be sold as cheaper units, as they were reliable at the lower clock speed, or were below the thermal envelope.
Later on in the product lifetime the yield improved to the point that they were simply taking the full speed chips and derating them to fill the sales orders for the low speed devices. Otherwise the full spec devices, so they were easy to overclock as you simply took them back to rating and could go further as well.
Read about these fake chips 25 years ago XD
My guess was the one on the bottom because it has a lighter color shade.
i have a Pentium 133 that has the A80502-133 instead of A80502133. and a Pentium 75 that is like A8050275, without a dash before 75. some unique looking CPUs.
OE relabeled microchips aren't unusual, at least they weren't in the '90s-'00s. Sonnet Technologies had a write-up for some of their old Mac CPU upgrades where such chips are used, explaining that often these chips were originally labeled for a specific customer order that was later cancelled (for example: customer needs 3000 400MHz chips where these parts regularly qualify from 400-500MHz, so the OE will just certify the whole production lot as 400MHz to satisfy the order), but since the chips were actually capable of running at different (often faster) speeds, they were requalified, relabeled, and resold.
Hi, do exist fake speeds on latest MMX non ceramic Pentiums? Like 200Mhz and 233MHz, maybe mine are fake and I don't know :S
Thanks!
I've never seen a faked one in the plastic package.
i remember working on a old pentium like that the coating came off with the thermal and heat sync i nver thought much about but it may have been on of these fakes lol
High Quality fakes from the 90´s ! Amazing haha
This made me check my collection... I only have early ones with iPP on the back, so they could be fake.
And I just realized, that I have one that is an golden ES.
Tillamook's a pretty decent little town. Has a old WWII-era Navy base that got converted into a aviation museum with some nice specimen including a Aero-Spacelines Mini Guppy. The silage smell gets to be a bit much, though.
Fascinating
i want that processor :o what a nice piece of Computing history!
