Honestly, I'm not sure. The computer was built at cyberpowerpc.com. As far as I'm able to tell, they did a fine job. I've only opened it once to install the ram I bought. Didn't check anything else.

For your E8400, use RealTemp for monitroing your temps. As for the 3.6GHz OC, I have mine 24/7 Orthos stable at 1.225 volts. My temps, under load, reach mid 40's and it stays mid 30's on idle. Hope this helps you out some.

Also:

Multiplier for CPU at 9x
FSB set to 400

That is all you should change to get the 3.6GHz. Make sure your volts for this CPU never go above 1.3625 volts. Per Intel website:

I'm at work right now, but when I get home, I'll do what you folks asked and post it in the thread.

I'm not looking for an insane OC, but I think that anywhere from 3.6 to 3.8 ghz is reasonable.

Also, with the multiplier question, is the range from 6.0 to 9.0 sufficient? Does the multiplier depend on the BIOS version? MB?

Lastly, with regards to my cooling ChillTEC - is that a good unit to have for CPU OC cooling?
The multiplier range from 6 - 9 is correct. You make the rest of the adjustments to your FSB setting, which at stock is 333MHz.

As far as your CPU cooler goes, it might have been a little too much. The 45nm processors don't run as hot as the 65nm processors. But, the cooler the better, so it is not a total waste either. IMO of course.

What are your temps with stock settings (idle and load)--we might be able to gauge a poor HSF set if these are generally higher than expected--reviews of that HSF show that it should keep the CPU quite cool--one I saw with a E6700 at 3.2 kept it at high 40C's...

I can tell you that, while I know it's not too accurate, the displace for my cooler shows the chip at 77-79F. I'll check it with RealTemp when I get home.

That's at idle.

Hmm... Let's be clear here--are we talking Fahrenheit or Celsius temperatures? 'Cause if it's F, like you mentioned above, then all is well (and with a TEC, it is possible to have sub-ambient temps, which i'm assuing 77F is below your ambients...). But definitely go with what RealTemp reports, and not the display on that HSF--some users report that the temp display never changes from a certain value regardless of load (which can't be right...).

Seire, post your CPU-Z, Real Temp, and HW Monitor picture from stock settings. You shouldn't OC right now. E8400 is capable of building a high tower, but firstly, it is important to set the base firm and estabilished.

not all hardware is the same. your ram is on a divider, so it may look like 333/800, 333/667, etc. at 400mhz, you should start off at 333/667, that is a 2/1 ratio and at 400mhz FSB, will end up at DDR2 800 (stable).

also, you will most likely need to manually increase your cpu voltage. i have to add 37.5mV to be stable at 3.6GHz, so manually set your cpu voltage to ~1.26V. if that works (boots), run a quick stability test. if it passes, try lowering your voltage until you cannot boot into windows. when you can't boot, increase the voltage, boot into windows and run a stability test.

once you get your cpu stable, you can then start oc'ing the ram. change the dividers to end up with a higher speed. try to boot. if not, slightly increase your dram voltage. but try to stay under 2V on your ram for right now. which should be good for a DDR2 960 speed (5:6 ratio, or 333/800). but your ram should be able to reach DDR2 1000 at about 1.9-2.0V (4:5 ratio, or 333/667 @ 400mhz fsb).

Okay folks. Here's the information you requested.

The computer is completely de-clocked and at idle.

Thanks in advance for the help!

Hmm...36C idle is a bit on the warm side, but depending on ambients, quite within the acceptable range for normal air cooling. However, you don't have strict air cooling...I'd expect your idle temp to be much lower with a TEC solution... My instinct is that the seating of the HSF is bad, or too much/too little thermal paste was applied. If you're comfortable with it, i'd suggest reseating the HSF, and applying a proper amount of thermal paste in the proper method. And while you're at it, if you have the means, test to see if the TEC plate actually works--which might be difficult, and I don't have a suggestion on how to do so at the moment (and it's getting late and I'm tired from moving the gf to the new place today--maybe I'll be more coherent/helpful in the morning...). For now, I'd say stock, you're within safe limits--but the OC is the problem...lemme think about it more...
