My guess with the '5X' jumper would be that it's '2.5X' and the silkscreen got cut off. Although with things like Socket 6 being out there, you do have to wonder what was planned at one time. There was a DX3 planned for 2.5X, but there's no telling if there were later plans to re-purpose those pins as AMD did, where they had the 5x86 'double up' the multiplier to 4X mode when the board was set to 2X, where 2.5X might have similarly doubled to be 5X on something that never saw the light of day. Most chips don't seem to like running with the jumpers in 2.5X positions, they either ignore it or just refuse to start. As Pentium prices came down, I suppose Intel didn't want the 486 platform eating its sales - plus AMD and Cyrix had chips for that platform and didn't have CPUs for Pentium boards yet, so if Intel could kill off the 486, it'd also have a chance of killing off AMD's sales at the very least, meaning Intel would only have to contend with the upcoming 6x86 for a little while. With CPUs that won't go into WB mode, I've found that if the board has jumper settings for a DX2WB (sometimes marked as P24D - _not_ P24T, or DX2 OverDrive), it'll quite often get that feature to work. It's almost like the CPUs have some kind of fall-back for this configuration, maybe so they would work on older boards. Obviously you have to make sure you don't change the voltage to 5V, as some silkscreens don't say what the jumpers you need to change are actually doing. Quake performance is weird on 486s, so the cache is probably only partly to blame. Recently I tried pushing an AMD 5x86 up to 180MHz. It got there, but along the way the frame rate stayed at 17.1 at 150, 160 and 120MHz. Only when the CPU was running at 180MHz did it jump to 19.1, even though I had to enable the PCI divider at that point.
Well I will have to tick that jumper setting to "5x" and just see what happens. I wonder if there is a jumper setting for the P24D thought the board is somewhat sparring in jumpers compared to some others like the M919. I find it interesting that the default setting in the bios left the system in a less than optimal state and I could see quite a few customers wondering why their shinny new Gateway system was slow.
@@rustymixer2886 Sounds like a video idea. Mpeg video accelerator built into a video card I would say yes, but natively IDK! If it does I would think the struggle would be quite real.
I liked those Packard Bell keyboards from the 486 to early socket 5 era. BTC dome with slider. They felt almost mechanical but not technically a true mechanical keyboard. And honestly this is the first time I've ever seen an Intel 486 chipset with PCI. I only thought UMC did that but a quick look at Wikipedia shows they made 3 PCI chipsets for the 486... Mind blown.
Intel 486 chipsets are out there but rare to find. It was by luck I found the ones I have during my "Vintage computer haul" video series of an old at home repair shop I was getting stuff from. I also have one from HighTreason610.
Back in the day they planned a 150 and even a 160MHz 486. It was never released because even the slowest Pentium did so much better so everybody lost intrest in the 486. I went from a 486 DX2 66MHz to a Pentium MMX 166MHz for example. But I'm curious how a 150 or 160MHz 486 would perform. Not sure how far you can push these processors but crank up the voltage and slap on a proper heatsink and entertain us! :D
@@WaybackTECH I don't think I've ever encountered a AMD 5x86 133MHz that wouldn't OC to 166MHz. I know with the right board and luck you can get them to 180MHz and rumor is that if the stars align just right and the correct rituals are performed the mythical 200MHz has been achieved.
I have been on a hiatus for awhile. I was going thru stuff again tonight to thin things out and got the old tingle. I have been sitting on a CompUSA computer for about 4 years now, thinking that might be my next video.
That mobo has the CMD640 IDE chip, which is known to corrupt data (google it). I highly recommend not using that onboard IDE controller! Btw, a DX4-100 definitely needs a fan or at least a huge heatsink.
The terms “PATA” or “Parallel ATA” did not exist back then, they were called “IDE” or “EIDE” or “ATA” It wasn’t until SATA was introduced that “PATA” became a thing (some people said)
@@jonchapman6821 Yes. When Sata was introduced traditional IDE was renamed to PATA. I like to keep to terminology that fits the era I am working on. SATA is almost dead now too with M.2 PCIE. Funny that.

13:30 Dont think I've ever seen green eyes on a cat like that. Purrty.
Hello there. Missed your channel
I will be back into the groove soon. Just got burned out and summer things took over.

Dx4100 was my first build when I was 11 or 12.

The ADZ AMD 586-133 chip is said to have been rated for 160Mhz though such markings never came to be.
@@WaybackTECH I don't think I've ever encountered a AMD 5x86 133MHz that wouldn't OC to 166MHz. I know with the right board and luck you can get them to 180MHz and rumor is that if the stars align just right and the correct rituals are performed the mythical 200MHz has been achieved.
So 486dx4 is only 100mhz? Isnt there a higher dx4?
I had one then got the dx4 150 AMD version ttgough
OKAY WHEN IS THE NEXT VIDEO 😁

@@WaybackTECHI hear yeah, CompUSA! dude that would be awesome.
careful, I've had CPS (CPU Protective Services ) called on me more then once for running a 486 heatsink/fanless before.
I remember a live stream of such comments of my K5 even though it was just a photo shot and not of the actual board as it was in use

God's name is Ares, Aries is a sign in the zodiac :D Nice video! Thanks!
not a bad board since it came out of a gateway I think it is a micronics
I think so as well.
you say stick and play. Its more like Plug and pray. Kids have is so easy these days, makes me sick lol
