I don't think the problem is related to Akos' apps either. The first reported occurences happened with regular Albert 4.37. If it is a coding issue, it's in the base code (and Akos has "optimized" the bug along with everything else). Since it is still an "unknown", I just thought I'd help publicize the effort to gather data on it again.

Well done. ;-)
I think the error should be reproduceable if the WU is known and the original is still available. If such an error could be caused by interference with other programs, we should have errors under Windows all the time.

Some time ago I had some more errors of this type at an Athlon XP under W2k , but I didn't report. With Linux this has never happened so far.

Memory access errors can also be caused by overclocking.

So true.
I started getting those and sometimes full reboots ( with WinXP Pro on a 3GHz P4 ) as I'd 'forgotten' that I'd overclocked ( with a supplied GigaByte utility ) at one point in the distant past - but had later put in akosf's optimals. The problem went away when I put clocking back to standard spec's, including for the video card and bus too.
Cheers, Mike.

I have made this letter longer than usual because I lack the time to make it shorter ...

It was a common problem at SETI when Crunch3r came out with his optimized apps. If you OC'd (either CPU or memory) you were guarenteed a violation error. Besides, an good optimized app at normal speed will beat the standard app while OC'd. Extend the life of your system and let the app do the work. :)

Not to mention that you'd also discover fans, heatsinks, thermal paste etc... that then needed reviewing with the faster apps too. Laptops especially, which I've always found generically marginal with cooling in various situations. It really does pay to set the BIOS hardware alarms sensibly, and respond accordingly, rather than raise the thresholds 'til it shuts up. :-)

I'm running a 15% overclock

I'm running a 15% overclock for the life of this system(3.5yrs), less a month at stock for breakin. Overclocking results are usually better if you do this. I have been using optimised apps for seti now for about a year and Akos apps for several weeks. Never a problem. And that 15% overclock gives me about 20% performance increase. But IMO the reason most have difficulties overclocking is because they are using generic parts in prebuilt systems. Build your own system(s) and you will always be more satisfied with it.

Exactly, in my case Thermaltake BIG Typhoon is the ultimate answer on any CPU overheat problems :-)

My watercooling rig's

My watercooling rig's handling a 24% (1.35-1.675) overvolt and 30% (2-2.6) overclock. Can your volcano do the same?

No, but then it can't spring

No, but then it can't spring a leak either ;)
My cpu is now at stock voltage but I've had mine running Prime95 stable at higher clockspeeds with higher voltage. I was limited by heating of the northbridge not the cpu. Some active cooling there and I would feel comfortable about uping it again.

Edit: One of these would be nice to have http://www.crazypc.com/items/9290GT.html .
Now we are talking cooling!
