- 🔧More Ram Testing Options with a Memtest86 Walk-through. Our 3rd video of this 3 part Ram series. Adding options to our trouble shooting toolbox to try and help encourage and empower some system owners to test installed RAM. Particularly newly installed RAM to identify that it is error-free and fully compatible. Before any issues present themselves later-on that might end up being memory related but not being identified before causing future trouble-shooting issues and frustrations.
It's a full walk through just to help any system owners who may fee intimidated by the sound of the process of running a memory test outside of the OS. So it's little lengthy. But we hope it helps reveal that it's something that system owners can accomplish pretty quickly while helping to overcome any feelings of extreme difficulty about the process.
We'll also upload a separate video of Recovering lost USB drive space portion

Change the playback speed to 1.75 x and this is watchable. You’re welcome.
thanks for the tutorial. the results I had was FAIL on 2 ram but PASS when testing the ram and slots individually. any advice for me? i just had my PC 2 weeks ago and I've been consistently getting BSOD since then.
Sorry to hear. Which make and model motherboard, cpu and RAM are in system? How many RAM modules are installed? Were RAM sticks purchased in a kit?
I'm experiencing something weird. I just built myself a 2700X + Gigabyte B450M Aorus Elite + Teamgroup dual channel (2x8) DDR4-3600. Placed the DIMMs in slots 2 and 4. Memtest86 fails at 3200MT/s and above using XMP timings. Switched the DIMMs to slots 1 and 3, got even more errors at 3200. Switched back to slots 2 and 4 and now Memtest86 passes 3200 twice already. Ok why is it suddenly running well now?? 3600 is still failing but I think it's because of the memory controller and not the DIMMs.
It could have been a "Hard" error involving incorrect or impartial installation. Possibly something that was resolved with reseating of the RAM. Maybe the contacts were slightly mis-aligned or one of the sticks didn't click all the way into the slot. On new motherboards, especially, some of the slots can be quite tight and stiff and be difficult to tell if the stick clicked all the way into place. It can be tricky tracking down RAM issues.
But sometimes there can also be errors referred to as "intermittent". Which can make the process more difficult and can also explain why the errors aren't uncovered every test. But as memtest86 states, all errors should be considered as a problem until they are resolved and confirmed as being eliminated. You can check out the 3 minute and 48 second point in the video linked here and pause to read down some of memtest86 memory trouble shooting info sheet. ua-cam.com/video/ulFrVWHAUjA/v-deo.html
You could try some additional testing to see if there are further signs of incompatibility or intermittent errors. On a previous video we included a list from Cisco where they list some differences between "Hard" and "Soft" Errors. You can check out the portion of that video at this link and pause the video to read down the list of some of those more common issues that could lead to Soft and/or Hard errors. ua-cam.com/video/ulFrVWHAUjA/v-deo.html or the cisco troubleshooting info sheet mentioned is located here www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/116135-trouble-6500-parity-00.html
You could try testing again utilizing HCI Memtest (from within Windows), to see if any errors are picked up during that test. It can be downloaded from their web site. hcidesign.com/memtest/
As HCI Memtest states: "Empirically we have found that the vast majority of errors are found in just a few minutes. 60% of bad RAM is detected after just 10% MemTest coverage. Running the test 10 times longer (100% coverage) raises the bad RAM detection rate to 95%. The remaining 5% are intermittent errors. Unfortunately, there's no way to speed up detection of intermittent errors - you have to wait for them to happen."
The Pro version of HCI Memtest is $5 for digital download and it includes an automation of the RAM allotment process hcidesign.com/memtest/purchase.html. It can be worth it if you are going to use the test often. Otherwise, with the free version you have to open many instances of the test manually as we walked through at this portion of the HCI Memtest walk through ua-cam.com/video/eEo-QethjqE/v-deo.html
We did a walk through for HCI Memtest as well. Though we did a fast paced and maybe too much variety in the format for some people who didn't like it or had trouble following along or said the sound levels were inconsistent on their audio during some portions of that video. But if you want to see if you can get through that walk through you can check it out here ua-cam.com/video/eEo-QethjqE/v-deo.html
*You might want to also temporarily disable Windows Virtual Memory so that HCI Memtest doesn't start testing Hard Drive memory (which they state it can and will do if it runs out of RAM). To disable you can go into Settings - system - about - advanced system settings on the right column - Performance Settings in the pop up box - Advanced Tab - Change button - Then Select "No Paging File" for each hard drive and press "set" button each time. If still not sure how to disable Virtual Memory, we did a very quick skit of walking-through this process at the 6 min 50 second point of this video ua-cam.com/video/eEo-QethjqE/v-deo.html Can re-enable virtual memory once testing is finished.
But sometimes it can be a solely a RAM issue, solely a MOTHERBOARD issue, solely a CPU issue, or all of those combined due to incompatibility. With incompatibility it's best to return and replace if possible with a better suited make and model of RAM for the motherboard & cpu in the system. Other times it can be one of those other "hard" or "soft" error culprits as well. Usually a motherboard manufacturer will list a RAM compatibility sheet on their motherboard support pages. You can try to cross check that list with the RAM you paired with the MB. But this usually isn't all that helpful because many RAM manufacturers do not go through the validation process to prove compatibility, especially if their RAM is released well after that motherboard. Even if the RAM they manufacture will run fine on the motherboard.
But if unable to track down the error issue and decide to return due to compatibility concerns, the motherboard manufacturer's RAM QVL list can give you a select list of RAM to consider for replacement which the manufacture has certified as being suitable for that specific motherboard.
Let us know if you do further testing and it reveals more issues or finishes without error.
Best Wishes.
@@RedEyeCentral thanks man. That's quite an extensive guide there. I really appreciate it. I'm happily running it at 3200 now, 16-18-18-38, with tRC = 60. Memtest86 reports performance to be 17.7GB/s, which seems better than the screenshots I've seen of Memtest86 texting DDR4-3200 DIMMs. Ran the test 3-4 times and no errors popped up. Now I'm having graphics issues that are related to drivers I would think. I'm still running old PC titles like Unreal Tournament 2004 and they get very regular stutters with my new (for 2016!) GTX 1050 Ti.
how long does it take and is it ok to do it with 2 rams inserted at a time or should i test it individually to see if anything is bad
I can’t exit memtest
During testing you tried to press ESC or C key and then pressed 2 for the 2nd option? By "can't exit" as you mentioned what happens? It just non-responsive? If stuck in the main menu, look for the capital letters that are highlighted. Press that letter to choose that option. For example: to Exit from there, press E key.

Demo of selecting main menu options at 10:25s in vid above
Let us know if the issue resolves.
RedEyeReview I exited it. all I did was turn off my pc and then unplug my usb and then turned it back on
@@therealilxaiden Thanks for the feedback and letting us know how you resolved the issue on your system! Glad to hear it's been resolved. If it gets stuck in a boot loop and keeps booting to the USB drive and re-running memtest86, then in the bios the boot priority options might need to be changed. If it happens again in the future with the usb drive connected to the system, check the bios hard drive boot priorities and set first priority to boot from the hard drive on which the Operating system is installed.
That should make it so the system boots from the hard drive and continues to load the operating system (Windows, linux, etc) as normal. And if ever want to run memtest86 or anything else from usb again, can re-enter the bios and change the 1st boot priority back to the USB drive for a single boot. And change it back when finished. Or if the bios has a hotkey boot menu option can use that key to select a one time boot from the usb in the future.
Boot menu hotkey demo at the 6:39s mark.
best wishes
Talk normally ffs
You should not do any talking with that kind of made-up voice, making that idiotic accent kind of ruins everything
