i7 975 Extreme...what am I doing wrong? - Page 4

post #31 of 40
Thread Starter 
Okay, got that all fixed up now.

Does anyone know what kind of CPU temps I should expect out of a 975 @ 30x multiplier (4ghz) with a proper H70 or similar cooler install? Just trying to get a baseline to know if I did everything right. I'm at 76 C under full sustained load and just wondering if a good thermal paste instead of the stuff that comes with the H70 would buy me a few degrees.

Thanks again.

76C sounds OK. i7s can tolerate those temps

But is 76C okay for it being only 30x multiplied instead of like 32x or something? It's between 76C and 80C.

What kind of temps are you running and what type of cooling etc?

You can't just up the multi without adding voltage or getting better cooling.

That's like in F&F when Jesse says "You can't just jump in the right with Ali cause you think you can box." Same goes with overclocking. Don't just do it without actually understanding what's going on.

Now that you have good cooling OC the hell out of that thing. As long as temps are below 80C sustained.

Also have you ran Prime95 for a few hours along with OCCT: Linpack for a good couple hours as well to ensure stability?

The thermal paste on the cold plate of the H70 is some of the best stuff on the market and is ages ahead of the likes of say Arctic Silver 5. Don't replace it.

If anything get new fans for the H70 that have more static pressure.

the "people" told you wrong, get an aftermarket cooler, then post back here.. A good one too. Thermalright Ultra 120 Extreme, Noctua NH-D14, Prolimatech Megahalems, Corsair H70 - Google any of them

Also fill out system specs here - http://www.overclock.net/specs.php?do=addsystem


For overclocking on the 9xx i7's you can raise the bclk and use the higher multi if you run into a bclk wall. But the 9xx series generally do 200 bclk on average, so you only need a 20x multi for 4.0.
You will need to adjust voltage too, and with stock cooling its just not going to handle it...
+1 on a good CPU cooler!

Some of these boards also have a "feature" that it drops clocks under high loads at high clocks. It basically dropped it down from 21x to 20x. I had to find a custom bios for my P6T7 that let it remain at high clocks. I had a P6T which also did the same thing, but since I never used it much, I never d/l the custom bios for it.
1st sorry for busting in on the thread.....

Where did you find a custom bios? I am looking for a custom bios for my Rampage III extreme, with some specific changes and mods....
