Obviously there could be a number of reasons this happened but really when you make a post like this you need to include more information?

What is the system you are running? (CPU. Mobo, Mem, PSU etc).

What are the details of your overclock? Did you run any stability tests (Prime etc) to test your overclock?

Have you tried putting your system back to stock speeds to see if the problem is still there?

I had an issue with some builds recently, they would just *switch off*, the worrying thing was they still did this once I set the system back to stock.

Took me a week to finally get to the bottom of the problems which was . . . . . . . A faulty CPU!

In fact it was *THREE* faulty CPU's (Athlon 64 X2 3800+) so I sent them back and got replacements and they work great!

3800+ @ 2.8 280x10 @ 1.5v
2gb geil ram @200mhz
DFI NF4
enermax 480w

no stability tests as i had no net connection. it ran 32mb superpi fine though every time and 3dmark06 and AQ3. only ones i had...
 
Big.Wayne said:
Is that a 3800+ or a dual core x2 3800+ ?

dual core...

and at stock it just did the exact same thing whilst burning a CD.

i was running the core temp program as well on both times though and since not using a temp program its not crashed. :confused: i stressed it on orthos CPU stress test yesterday for 1 hour as well. didnt have enough time for longer...

When did you buy that chip and do u have the codes/steppings handy?

[edit] yeah CoreTemp has caused the PC to just switch off before however the same PC has switched off without CoreTemp running.

got it friday from overclockers and the stepping is LCB9E 0719RPMW.

its now been running for 3 hrs on blend on both cores using speedfan as a temp monitor...
 
this is how it is currently... i have no idea which core is which or anything...

Cool I got the exact same chip. Do me a favour and *don't* run Coretemp and see if your system shuts down again.

So far I have been running my one a week and no shut downs. Those temps look a bit warm, what cooling u using?

i havent run coretemp since and its been stable... :confused:

cooling, i am using AS5 and arctic cooler pro.

temps are crap on it but its got good contact (reseated it twice!) so i'm assuming the internal conduction to the IHS is crap.

maybe next step is to take off the IHS but then i dont know if it would connect to the HSF properly?

hmmm what about the PWM temp? whats that? i only ask as its a lot higher now than when i had my Opty in. used to run at 50C loaded but now its 57-60C+. :confused:

the PWM's (pulse width modulation) are the power mosfets responsible for powering the cpu. dont worry, they are good for up to 100c or so.

As James said, also its normal for Dual-Cores to make the PWM heatup a lot more than a mono-core.

Having a 3rd party heatsink that blows some air onto the PWM heatsink helps bring the temps back down.

My PWM temps are now similar to my CPU load temps since I replaced the stock cooler with a Thermalright Xp-120 that blows cool air straight down onto both the CPU and PWM heatsink.

I just noticed that Speedfan is reporting your vCore at 1.31v which is a bit low, change that to 1.35vCore in BIOS. The chips can run at 1.300vCore but I had some weird issues myself.

currently im in orthos at 2.6 260x10 @ 1.34v according to speedfan and 1.36 according to bios. i have no idea which to believe... and i have no idea which temperature to believe as there's such a vast difference.

is there a 'guarenteed' program to measure both? as in 'this is the best and most accurate and will definitely tell if your chip will blow up' type program. i used MBM5 on my single core opty which was great but it doesn't work with dual core.

you cant take the IHS off on am2's (assuming its am2 not 939), trying it at stock is worth a try i guess
Click to expand...

its S939 and yes i know about the IHS being soldered onto AM2s now. if i can i dont mind butchering this one (only £40 CPU.... ) if it will work but no point if i need watercooling...
 
ok 40 mins of orthos and its not crashed even with me messing around doing other stuff which should make it trip up.

time to up it to 2.8. i have a feeling my RAM is a bit funny about it as it doesnt like going 1mhz over stock.
 
it aint happening.... 2.6 is the closest i can get stable so far. i think its the ram maybe although i REALLY want to take the IHS off and cool this bad boy down more...

This was screengrabbed 30 mins ago, it has previously passed a 24 hour loop of the same test at 2600MHz.

Having to take this machine apart now as I need the ASUS A8N-E for a build I am doing for someone. Had a quick test at 2800MHz but it failed prime quickly using 1.3500vCore - 1.3750vCore - 1.4000vCore.

That is as far as its going using the stock HSF but I will give it another go once I got the Thermalright XP-120 sitting on top of it (and probably using an ASUS A8N-SLI Premium).

Nice overclocks and no reboots so far, touch wood, and its been running Prime for a week nearly!
 
hmmm upped it to 2.7 and 1.38 according to speedfan and its priming nicely... only do it for a few hours simply because its not worth the earache for leaving it on all night.
