i7 920 temps and voltages

post #1 of 19
Thread Starter 
Hey guys, I have been overclocking my 920 the last few days and wanted to ask how my settings look to you guys and if my temps/voltages look safe.

i7 920 Bloomfield C0/C1
Core clock - 3.6GHz
vcore - 1.175
Multiplier - 20
Bclk - 180
Max temp under Prime95 - 66c
CPU cooler - Cooler Master Gemini II

Everything look good? Can I go higher that 3.6GHz on air, or am I just looking for problems? Thanks for the help.

have you tested your system for stability?

A little bit, but not much. I was thinking of running Prime95 over night, but i'm not sure about doing it. As of right now games and programs work fine, not a single hiccup so far.

Yes this.
Is it with the stock Intel heat sink?
You can definitely go higher if your cooler can handle it.
If on a stock cooler maybe go to 3.8, but that is as far I would go.
Put the Vcore to 1.2 and see how far she goes, and you must STRESS test!!!!!!

Good Luck and have fun.

It is a MUST, to do a stress test.
I say download Linx do a 20 run test, then test with Prime95 overnight or for at least 12 hours.

Then we'll see if those temps are worth it, and if it's worth it to further overclock.

I have a Cooler Master Gemini II heatsink on it right now. What program should I use to stress it?

I'd say that that is a good start for a C0 chip.
The temps seem a little bit on the high side for the voltage however I am unfamiliar with the performance of that cooler.
I would aim for a maximum of 75c or so. You do have a little more headroom go ahead and bump it up to 1.2v and see if you can go up a little more.
Just remember that the C0 chips are not as good as the newer ones. Some struggle to reach 4Ghz..
Make sure to run stability and temperature tests throughout your overclocking.

Oh sweat another EVGA user.
Yeah put Vcore to 1.2 and see how she does.
Do you have things set to Auto?
I suggest from the bat put your RAM to specs, put your Vcore to 1.2 and see if you can boot and stress at 3.8.
The max I would do for now is a 1.25 Vcore and slowly creep your Blck up and make sure you Adjust your QPI/VTT.

Again as said before C0s aren't known for great temps/Vcore at 4.0 so slow and steady my friend.
If you can get by with a 191 Blck should be fine, however monitor temps.

It doesn't matter if your pc can run a game with out a hiccup or what not, it's a matter of the system as a "Whole" being stable.
And these stress tests can ensure your system is stable enough for normal 24/7 use.
Some people actually bench for 12+ hours to be considered stable, even Folding@home stable, so keep that in mind.

Again have fun!!

I thought D0 are the one with better temps and lower voltages for higher overclocks?

Ran LinX, like you suggested, max temp of 67c without issues. I will run prime over night at 3.6GHz and if I don't encounter any issues bump it up to 3.8 tomorrow and run prime some more.
