Memtest86 having trouble with system?

[Rubycon]

NEVER had a problem with stability and Memtest was run by accident - leaving a boot cd in the machine. Found system process halted by exception (in memtest - WTH?)

Sooo I reboot (hard reset was required) and let it fire up. Fine until test six. BAM! Ton of errors! Bring everything back to stock, try again - same results. Fine, removed two sticks of ram - same results. One stick, ditto. Tried different RAM - same results. Tried UNDERCLOCKING CPU AND RAM - same results!

This system is what I would call stable - it will do LARGE memory test Prime95 for days without a hiccup. I've seen systems that flunk Prime95 and will do the same in Memtest. I have NOT seen a system that takes an immediate dump (on test 6) in memtest yet passes any other test in Windows. Makes no sense!

I REALLY hope this is a glitch that can be ignored. It is a real PIA if I have to RMA anything!

If you tried diferent ram and still flunked, then I would suspect the memory slot on the
mobo and test for that.

Using my quantum entanglement crystal ball, I interpret what you said to mean that you had a self booting memtest 86+ ISO CD burnt, and left it in slot while booting to XP.

So, the big questions are:
Did the CD ever work before this/
Did the error message have an exception description/number?
We really need that.

Before hearing your answers, perhaps memtest cant detect your FX60 correctly.
If prime works, I would inore it.
Memtest also checks CPU - L1 L2 cache
Reading my crystal ball again - your statement "brought everything back to stock" might mean you were severely overclocking, whilst you were using a testing CD with a program that didnt recognize your CPU.

I believe that's what the problem is - the software needs an update. It's not detecting the CPU / Chipset properly.

The errors fall in addresses within the L1/L2 cache too which about made me flip a bit or two.

Never thought of trying memtest as there was NEVER suspicion of memory errors. Just burned the ISO with Nero on the machine. Funny how that works.

gotta make sure you get memtest 86 "plus", not Nov 04 memtest 86
but even that is only Oct 05

Yes 1.65+ is the version that we have.

I'd try redownloading & burning a new CD before I worried about any of the components.

Tried UNDERCLOCKING CPU AND RAM - same results!

Have you tried the rated RAM timings? I would also bump the VDIMM up a notch at a time to see if it passes. If my rigs do not pass Memtest86+, I tweak and troubleshoot until the issue is found.....

Tried everything as recommended by The Ram Guy (Corsair forum) with no change. They are "investigating". hehe

Every other thing that's run on it has no issues.

I've seen older versions of Memtest would reboot 875/865 machines immediately if run in dual channel mode. Perhaps this one doesn't recognize this processor? I dunno this is the only FX60 system onboard that I can test.
