MemTest86 v9.5 Beta 1 Release (2022-09-30 Update - Beta testing is now closed)

[g126]

Great idea - DMA test!

I've downloaded it and I'm running it now, but I find it to be very SLOW... It's 3h55m and it's about 34% though the 3rd pass.

It usually takes around 4/5 hours to go through the whole cycle of tests 4 times.

Specs: 12900KS with 32GB of DDR5@6000MHz.

Took 7h36m to do 4 iterations of this test (see report attached).

New Features

• Added new experimental memory test as Test 14 [DMA test]. This test exercises the disk controller's DMA hardware to perform memory access, bypassing the CPU. 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.

Fixes/Enhancements

• Fixed hammer test incorrectly running in single-sided mode in Free version
• Fixed clock speed measurement failure for ARM chipsets due to cycle count register not being enabled
• Fixed bug in reading ECC error count registers for various Intel/AMD Ryzen chipsets
• Fixed reading ECC error status register for Intel Tiger Lake-H and Alder Lake chipsets
• Fixed ECC detection on Intel Ice Lake-SP chipsets
• Fixed ECC support for Intel Rocket Lake chipset variant
• Added ECC support for Ryzen Zen 3 50h-5fh chipset
• Added support for retrieving Intel Ice Lake-SP CPU info
• Added support for retrieving Ice Lake-SP RAM SPD data
• Added support for retrieving Ice Lake-SP RAM temperature data
• Updated blacklist

How to report problems

Either make a post here in the forum, or send us an email at the address listed on our contact page. When reporting an error please provide as much details as possible. 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. Sending us this will be of great help. Additionally a photograph of the problem would also be useful if possible/applicable.
