PC Crashes encoding Divx using AutoGK

[A1CSpence]

I've got an X2 3800 running @ 2.63ghz which is crashing intermittently. I can run Prime95 all day, play any game, and do just about anything, except encode video reliably. Sometimes it works, most of the time the computer locks up about 10 minutes into it.

Memtest passes just fine BTW.

I'm using the latest version of AutoGK. I've got a Scyth Ninja and four 120mm fans pushing air, so the processor isn't getting that hot, maybe 48C under full load. So what do you think the problem is? Thanks in advance.

2 x prime95?

Can you run AutoGK when your computer is not overclocked?

Which version of AutoGK, I was having some trouble with version 2.26 on all of my dual cores. I finaly got it to run, but can't remember what I did to get it working. The older version, 1.83, gave me no problems.

I ran Prime95 on both cores. It ran without incident until I stopped it after about 10 hours.

I am using AutoGK version 2.27. It encoded just fine before I overclocked.

I came across this article recently at Silent PC Review which leads me to believe it might be the northbridge.

"It could run Prime95, CPUBurn, protein folding or PCMark/3DMark indefinitely, but had occasional odd hangs or slowness running HD- or CD-intensive tasks. The behavior was consistent with lost IDE interrupts. I tried dialing back the clocks a bit and these symptoms disappeared. This led me to conclude that the performance limit in my system is set by the chipset (north and south bridges), not by the CPU or memory."

I'm using an Asus A8N-E. The northbridge HSF was removed and replaced with a fanless zalman heatsink.

I tried encoding a movie with the case closed, it crashed within 2 minutes.

I opened the case and put a 120mm fan blowing on the northbridge, and I'm encoding right now and have been for the past 15 minutes. So it appears that my northbridge is overheating. Reasonable?

Very reasonable......I would put an active cooler back on the chip then....

interesting.. so i guess 2 x priming doesnt use the NB.. haha

Prime is testing...

Cache = on chip
memory controller = on chip
memory = ram controller though on chip controller

not a HDD test or a vid card test which I believe the northbridge manages....

Do Prime for at least 24 hours before you say indefinitely. You claim to have run it for 10 hours. I've seem prime fail in the 13 hour, 16 hour, etc. I even had it fail once in the 23 hour (which really pissed me off, but thats another story).

So maby run prime a little longer, also run it for 12 hours with small, 12 hours blend, then 12 more hours with large, just to make sure.

Also, play Oblivion. That game seems to test out stability pretty well. (Quake 4 also seems to be my Memory OC test. It ALWAYS seems to freeze up Quake 4 if my memory isn't stable.)
