Changing ram modules, using only single modules or completely different ones for example different in speed and latencies always resulted in the same test number 7 failing seriously I was using the memtest+ 4.20 from the 12.2/rc1/x86 image written to a usb key / usb stick and booted from that stick on that uefi system from above. Eventually I used my older 12.1/x86 dvd iso booting via dvd rom drive and dvd rom, also having memtest+ version 4.20 and this now runs flawlessly on this same uefi machine, same configuration, only booting the memtest entry from the initial boot menu at pre-installation. This machine has uefi, but maybe there is a problem with booting the later generation iso image from usb keys / usb sticks in general at suse or maybe this is slightly a different memtest+ 4.20 and not really identical on 12.1 and 12.2 iso images? I am not really sure what to make of this behavior and where to pinpoint the source for this bug. maybe related bugs: http://bugzilla.novell.com/show_bug.cgi?id=773565 http://bugzilla.novell.com/show_bug.cgi?id=753574 maybe there is even some relation to: http://bugzilla.novell.com/show_bug.cgi?id=771552 Thanks and regards.

This system is a Intel motherboard with 8GB RAM (DDR3 - 4 2GB modules. I rotated the modules, removed so4 GB, changed slots for the pairs, etc. Always reports error at 0x08100000 even with 1 2GB module installed. This always occurs at start of test 7. Since this memory has worked for four years, and never had errors. I think its a test 7 problem.

This version 5.0.0 has different tests though and more extensive hardware support and detection. it didnt report errors on this same hardware in any of its tests. I was scared that my system was defective so I used that memtest+ 5 to verify this rather new hardware as I had thought it was a compatibility problem with 4.20, although it was odd. Its still weird that the newer 4.20 of 12.2 reports problems but the older 4.20 from the 12.1 doesnt have trouble http://forum.memtest.org/ redirects to http://forum.canardpc.com/forums/73-Memtest86-Official-forum then there is thread http://forum.canardpc.com/threads/68001-Memtest86-5.00-Beta-available-%21-Ne... it can do 64bit support, and multicpucore tests and so on greetings. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've the same problem with 12.2/x86 final iso image from usb key.
me too:-( I just wanted to test a PC with memtest using the official dual-sided 12.2 DVD. both 32bit and 64bit throw zillions errors for test # (random number sequence) starting at 129MB (PC has 2*2GB DIMMs). using the memtest on official 12.1 DVD works fine -- no errors at all, so the hw is ok and 12.2 media is broken. pitty:-(( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Anyone who still sees a dependency on the source medium type (USB vs. DVD) please speak up now or remain silent. There were _no_ source code changes AFAIK between 12.1 and 12.2 so we're most likely facing a compiler bug here.

ECX is, AFAIK "caller-save" by the ABI calling convention; and the asm inline calls rand(), which it does not declare.
