[opensuse] bizzare memtest behavior
Folks, I don't know if anyone has seen this behavior with memtest86+ (v1.70). I downloaded and tried the one from memtest's web page after hearing about some issues with the SuSE one. I have 6x1GB sticks in my machine and memtest is chugging along running tests at address 7537.3GB and of course failing. It clearly displays it found 6143MB of memory. The question is why is it testing memory at addresses above what it knows are valid?

I can't shed any light on the problem, but it certainly seems bizarre. It may be an issue for a bug report/email to the memtest86+ folks. The most bytes you could ever see with 6 Gig. is 6 * ( 2 ^30) = 6,442,450,944 bytes. Or, defining a MB as 1000K or 1000 * ( 2 ^ 10) = 1,024,000. Then 6 GB would be 6,144MB or 6,144,000,000B. Well below the weird 7537.3GB. Have you checked the release notes? -- David C. Rankin, J.D., P.E.

Interestingly enough, I though of something very different, namely that the PCI map hole was accidentally counted. But the difference (7537-6144)=1393 would be a bit high, well, unless you have a bunch of hottest graphic cards. /proc/iomem: 257 MB bd800000-cd9fffff : PCI Bus #01 33 MB cdb00000-cfcfffff : PCI Bus #01 127 MB d0000000-d7ffffff : 0000:00:00.0 so that's roughly 417 MB of mapped PCI space for me. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You're behind the times. The current version of MemTest86+ is 2.01. I've found that if you have the latest hardware, be it CPU or chipset, you need the latest MemTest86+. Get an up-to-date MemTest86+, burn it onto a bootable CD and see if that resolves the problem. http://www.memtest.org/ http://www.memtest.org/#downiso http://www.memtest.org/download/2.01/memtest86+-2.01.iso.gz

Or just copy it to /boot and add it to grub. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

True, but if you mess up with that, you've got a problem. Burning a CD is unlikely to mess up your boot configuration. Randall Schulz -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

By the way, when posting a question of this sort (low-level, hardware-oriented), you really should outline your hardware configuration. Tell us which CPU, which chipset and / or which mainboard manufacturer and model you're using.
