Question memtest86 OR memtest86+ ?

Hello!

I have the desktop with following hardware:
1. MB: ASUS P5QL/EPU
2. RAM: CM2X2048-8500-C5D ver1.2 2.1V 5-5-5-15 (2 x 2 GB)
3. CPU: Intel Dual-Core E6500
4. GPU: nVidia GeForce 9400 GT with binary driver

This machine is running for more than two years without any problem, with a default BIOS settings related to RAM, but during the last 2 or 3 months I get deadlock hangs once or twice a week. This machine runs Slackware-current 32 bit with custom compiled vanilla kernel with two additional patches - BFS and TuxOnIce. Deadlocks usually occur when there is no user activity - only rtorrent is running and two KDE4 sessions is open (with firefox, okular, claws-mail, goldendict, virtualbox, rxvt-unicode and other memory consuming apps).

This is excerpt from my syslog:

I just would like to get a clue - is this error related to the memory?

By default my BIOS set this memory to 5-5-5-18 and 1.8V @ 1066 MHz. I changed settings to 2.1V and 5-5-5-15. My BIOS doesn't allow me to change 1T/2T timings.

Anyway in both configs (default and custom) I get NO errors at all with memtest86+ 4.10 and get a lot of errors in test #7 (random number sequence) with memtest86 3.5a.

1. Should I try my memory @ 2.2V ? Is it safe? It's labeled as 2.1V.
2. Which test is more reliable - memtest86 or memtest86+ ?


Since I rose DRAM voltage (a week ago) 1.8V -> 2.1V I got NO errors in my OS. But I'm confused by memtest86 errors.

Thanks in advance!

Did you disable legacy usb in the bios? It is a known to cause errors in memtest.

Nope . I will try to do it tonight. Thank you for the clue!

UPD: I disabled and got no differences - errors with memtest86.

Ok, let's decide that memtest86+ is more reliable and 100% trusted. I like this version because I have no errors with it =)
