Default hardware error

I´ve got a MSI Neo3 + Intel Quad Core Q6600 (not overclocked) and Windows XP 64 Bit Edition.

I´m getting this message after running Prime95 (.27 version - occures for 32 and 64 bit version) + World of Warcraft):

[Oct 26 19:39] Worker starting
[Oct 26 19:39] Setting affinity to run worker on logical CPU #1

[Oct 26 19:41] Possible hardware failure, consult the readme.txt file.
[Oct 26 19:41] Continuing from last save file.
[Oct 26 19:41] Waiting five minutes before restarting.

I´ve already changed the RAM - it only occures if I have a lot of IO (for instance starting the WOW Game).

Don´t understand whats going on. Is it really a hardware error or some error in the client?

Greetings and thanks

Have you stress-tested your system before running actual exponent? How did you do it?
How many worker threads are working? How many threads have been assigned per single test?

Yeah works fine as long as I´m not doing something else on the machine (like playing World of Warcraft).

4 worker threads with 1 cpu thread each.

Still I don't know which stress test did you use...
Anyways, check your temperatures and... voltages, as getting errors while playing games might actually indicate some problem with PSU (if you're 100% sure that it's not RAM or CPU that's causing such problems).

Or some problem with the games in correctly restoring FPU registers

The saving & restoring is done by the operating system (in that case Windows XP 64 Bit) and not by the application.

I´ve formatted my system and installed Windows XP 32 Bit. Now it works without a problem (the same bios configuration).

So it´s a Prime95 (32 Bit or 64 Bit) problem or it is a Windows XP 64 Bit problem. Anyway I suggest don´t use Prime95 with Windows XP 64 (and perhaps Vista 64 Bit).

Formatting would also have removed anything that was installed before so it could have been a driver or something else running in the background not just Windows or Prime95.

But either way, I have never had any problems with Prime95 and Vista 64bit.

I use Prime95 64 bit (24.14) on Windows XP 64, and haven't had any problems. I have played a lot of Warhammer Online at the same time, and still no errors. I happen to be using a Q6600 (not overclocked) also.

I haven't tested my setup with WoW, but plan to after I re-enable my account (Nov 16th).

Yes, but it used to be that a few device drivers (even XP) were culprits in failing to save/restore FP registers.

As far as I know is the windows xp scheduler doing this work. The device drivers have no direct access to the saved fpu data.

Good. I'm glad that's cleaned up, when/wherever it happened, and is no longer a problem.
