I decided today that I want to try and OC my E8500 a bit.

Speczz:

https://img294.imageshack.us/img294/9228/specss.jpg

My CPU cooler is a Noctua NH-U12P, with just the one fan on it (so no push/pull). In an Antec P182 with its stock fans.

Without any OC at all, using prime95 for an hour:

Core Voltage    1.136
FSB                    333
Temp Min            44
Temp Max            60

After reading some reviews, forum posts, etc about both the Noctua and the E8500 it seems this is quite high.

I took the FSB to 400 (3.8GHz) with a core voltage of ~1.16 and the temps after about 15m of prime95 were 65+ which is too high from what I have been reading (the Intel specs say 72 max, but something about reducing that by 5 for 45nm CPUs?).

Point is, should I take my Noctua off and reseat it with some good thermal paste? Or is my CPU just shit. Cables are fairly neat, I dont think they are a problem.

"should I take my Noctua off and reseat it with some good thermal paste?"

it's always good to know, that there's even coverage and the cpu/cooler are seated tight. imo, worth the effort of tearing it down.

Guess I will. Who knows when I will be bothered though. Theres messing around in the BIOS and running stress tests while watching TV shows, then there is taking my heatsink out and re pasting and seating it.

70°C isn't the maximum temperature the CPU can run at, they just spec the maximum 'case temp'. It's a fairly worthless value. 60°C is totally fine. You shouldn't worry until you're approaching 80 degrees and up.
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

you got to 4ghz with 1.16 volts? wtf is this shit. And it could be room temp affecting it as well.

Well holy shit.

Reseated the fucker, and after wrestling with the fan mounting brackets its all back in.

5 minutes into a prim95 test...temp is 46/47 degrees. Thats ~12 degrees less than it was.

Nicely done, go OC it nao!

Stress tests aren't really an accurate representation of actual max temperatures when playing games. Unless you're playing BC2 or something. You're never going to reach the temperatures you get in stress tests whilst playing games.

For example, when I run Prime95 my computer BSoDs after about 3 seconds due to my OC. Never once had a problem ingame though, even when running BC2.

Before buying mine, I read that the E8500 will go to ~3.5-4Ghz on stock volts

Yeh I know. I am just a little paranoid. Would rather it never gets to a ridiculous temp.

And no cybargs, I didnt. Just ran prime95 for about 45 mins at 1.2 volts (fsb of 421) and it bluescreened.

I know I could probably leave it at that, but I just dont want to have it fuck up on me later when I cant be bothered tinkering.

ps. This was pretty much brought on entirely by BC2 Finray :p

~15 hours of stress test later, it hasnt gone above 70 and sits about about 65.

I assume on better cooling these easily get to like 4.5GHz?

If you got lucky and got a good batch one...

How is stability?

I got a Vendetta II cooler which performs better than a TRUE with 1 fan

Well it has only been overclocked for a day so far, but there was no errors running prime95 for 15 hours.

Prime95 was what I meant by stability testing

All you did was up the bus speed?

Also upped the voltage a bit, 1.136->1.216.

How did you figure the .xxx ?

I mean, wouldn't 1.2 do the same?

1.2 is what I wrote in the bios. It added certain decimals after that, I think it was 1.2125 or something. I had previously done testing before I reseated my heatsink on what voltage I would need. (1.15 didnt even get into windows, 1.18 got about 1 second into prime95)

It is always different in windows to what is claimed in the bios for some reason. Who knows. (is that "vdroop"? I read some shit about that).

Hmm ok..

I might try 422mhz and 1.2v sometime then (I have the same CPU and a P5Q )

Does your P5Q also auto over- & underclock CPU and Ram speeds as needed?

I assume its just speedstep, its a bios option.

Yeah... I was kinda confused the first time I started my "new PC" (1 year ago) and saw my delicious 1066mhz ram ran 400mhz...

derp...
