i7 920 overclocking thread

Is the vid the same thing as CPU voltage or is vcore the same thing as CPU voltage... I'm confused now. Are you saying that the max CPU voltage is only 1.365???

the max vid is 1.375v, a processors vid is the amount of voltage it tells the motherboard it needs to run at stock. just because that's the max vid doesn't mean it's the max voltage. imo you should be fine with that voltage.


vulcan: i have the same problem, i'm thinking it's our p6ts... i'm thinking about ordering a blood rage.

Okay, I'll try upping the voltages tomorrow and try again. I didn't think it needed to go much higher since I've seen a lot of posts claiming 3.8GHz on as little as 1.20v, but maybe they're just lucky.

In my opinion, it is not that high at all. If I remember right the VID range goes up to 1.375 (meaning that for it is possible that for some chips they would need that much voltage to run at stock speeds).

It also depends on how you are using your computer. 24/7 heavy folding or gaming and more casual usage.

The bios just goes with what was programmed in based on intel specs, not on any actual real-time evaluation of your system.

One area to experiment with is to up your VQPI voltage (to 1.35) and try lowering your cpu voltage.

I'm using it for graphic design and casual gaming mostly. Deninately not 24/7 run times.

Any rater its good to hear that my CPU Voltage of 1.375 is in the safe zone. How much higher could I go though... do you know where the limit is for a safe CPU voltage? I once heard somebody say that 1.45v was the limit, but that sounds high to me.

Here is first stable OC.

On you max safe voltage, you are now firmly in the realm of "opinion" and YMMV (your mileage may vary) based on the chip you have.

My opinion"is that there is diminishing marginal return in trying to bump it up more. Sure you can get and extra 100-200Mhz but at a big increase in voltage. Most importantly, will you actually see any of that 100-200Mhz increase in your day-to-day? I severely doubt it.

For me it is fun to experiment and see if you can get more, or do some non-stable superpi runs hoping that they system doesn't crash, but then I go back to normal usage at 4G with lower voltages for the day-to-day stuff.

Well just now I had to up my CPU Voltage to 1.385v and the QPI Voltage to 1.38v to keep my 4.025ghz overclock happy. Seems like kind of a lot to me... whtcha think? Maybe I need to toy around with other settings???

What are your idle / load temps?

[HardwarzFan]

Roughly 40/67. Is that pretty good?
