It's mostly visible when it's starting (like detecting memory controller and SPD information, before the main screen is even shown, it even looks like it got frozen, before it shows the first line, then it takes couple minutes, compared to maybe half minute when running from NVME. I was testing 9.5beta for last couple days (my workstation is showing 1 bit errors, but only when all 4 modules are used, each with 32GB - testing 2 and other 2 modules separately didn't show an error).ġ) Running memtest from USB drive is _significantly_ slower compared to running it from EFI partition on NVME drive, I had 9.4 version in NVME and 9.5beta on USB drive an I was assuming that the beta version has some extra debugging enabled, but now I've tried with 9.4 version on USB drive and it's also very slow. Additionally a photograph of the problem would also be useful if possible/applicable. If you are running on a USB drive, there should be a log file that has been generated in the EFI/BOOT directory called MemTest86.log. When reporting an error please provide as much details as possible. Added support for retrieving Ice Lake-SP RAM temperature dataĮither make a post here in the forum, or send us an email at the address listed on our contact page.Added support for retrieving Ice Lake-SP RAM SPD data.Added support for retrieving Intel Ice Lake-SP CPU info.Added ECC support for Ryzen Zen 3 50h-5fh chipset.Fixed ECC support for Intel Rocket Lake chipset variant.Fixed ECC detection on Intel Ice Lake-SP chipsets.Fixed reading ECC error status register for Intel Tiger Lake-H and Alder Lake chipsets.Fixed bug in reading ECC error count registers for various Intel/AMD Ryzen chipsets.Fixed clock speed measurement failure for ARM chipsets due to cycle count register not being enabled.Fixed hammer test incorrectly running in single-sided mode in Free version.The motivation for this test came from discovering a defective RAM module that did not produce errors when accessed via the CPU, but failed when files were read from disk via DMA. This test exercises the disk controller's DMA hardware to perform memory access, bypassing the CPU. Added new experimental memory test as Test 14.


As usual, the Free Edition is available for download on the normal MemTest86 download page. (Sep 30/2022 Update) MemTest86 v10.0 Pro and Site Edition can now be purchased from our sales page. Thank you to our beta testers for the bug reports and feedback.

As a result, MemTest86 v9.5 beta testing period is now over. (Sep 30/2022 Update) MemTest86 v10.0 has been officially released.
