PC Shutdown

[Stormcrow]

P30 I hear is the best for quads, the 680i is notorious for not playing nice with the Kentsfields. Look in the P32 thread in the Evga forums, I'm almost positive that it's mentioned P30 is the better BIOS but it could be P29. I'm running P31 myself, but with a Conroe so immune to the quad symptoms. The first problem is definitely an error in the BIOS, I get nearly the same thing when my RAM is just a tad unstable. Random shutdowns, a BSOD, or my favorite...the system freeze that makes my music halt in the middle of playing and screech at me. The 680i, especially Evga's reference model, is way too touchy when it comes to overclocking.
For the shutdown problem, that's usually Vista taking forever to shut down. Sometimes up to 3-4 minutes on my machine, especially when it's nagging about updates. Go to Regedit, then look for the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol". Change "WaitToKillServiceTimeout" from 20000 to 1000 and it should speed it up quite a bit.

See what I mean. Awesome response time. And as I recall It was Stormcrow's post I was referring to earlier about the P30 version being better for quad cores and the P31 version being better for dual cores. (I remember the Dragon)

Anyway, I flashed back to the P30 version and will try another small overclock as it seems my memory is ok. (Or would you recommend a longer test?)
I also changed the registry and will see if my PC will turn off tonight. Thanks again guys.

Ok. So I shut down my PC last night and get up this morning and the fans are still running. I let it sit for 6.5 hours. I'm thinking thats more than enough time for Vista to resolve whatever it needs. Hmm.

[Stormcrow]

Was it overclocked when you tried shutting it down, or is it doing this when at stock settings?

[Lord Gaebril]

Now that you mention it I think I did set it to 2.7 before I went to bed last night. I should return it stock speed? Should I return the whole BIOS to default then try or just set the FSB back to 1066 (as well as voltage)?

By the way I clocked it to 3.0 today and have had it running pretty much all day. I haven't run a stress test yet as i'm afraid my temps are to high. I'm at 46-40-39-42 at idle. And It goes up to 65-60-60-60 almost instantly when running stress test. Will run test when I get a heatsink on here that can actually handle the heat from this thing.

60C isn't a problem, that's actually the rated temperature for the Core 2's when under load. Quads can actually handle up to 80C no problem, but I heartily don't recommend it due to electron mitigation. Of course cooler temps are always a plus, and with a good HSF like the Zalman 9700 you can take it higher.
Try shutting down the system, and if it hangs for more then 5 minutes manually power it off. Then try it with the RAM and Proc at stock speeds, see if it continues.

One thing I just noticed was your using the Cosmos 1000, are you still using the stock fans? What's the voltage for the RAM right now?

[Lord Gaebril]

I have the stock fans in my case and my RAM is set to 2.1v in BIOS. I will try the shutdown tonight with the stock speeds.

But I have to finish Alvin and the Chipmunks with my kids.

[Lord Gaebril]

I set the BIOS back to stock settings and still no shut down. I had to leave today and it sat for 5 hours.


I did get a couple BSOD today so I'll probably back down the CPU OC for now.

I would suggest setting ALL hardware to stock speeds, including CPU, RAM, FSB and GPU... also while in the BIOS, check over the power settings.... in some cases it is either windows itself or a bad mobo that isn't sending the shutdown signal. Try a LiveCD of a Linux distro and choose shutdown from there. If it shuts down then it is windows, if not then it is either the BIOS or mobo
