i7 920 overclocking thread

[the$#!Za.]

Thanks for the reply and advice nebuchanezzar, King Of Babylon

Well I'm not having any temp issues at all with my stock heat-sink/fan and just thought hey, why not try for 3Ghz, but I guess the temp rises more than I thought. I'm going to have to find one of those overlocking for dummies tutorials.

Thanx,

For example, people seem to use the CPUZ validation for their 24/7 clocks of 4.0 Ghz. That always shows the x21 turbo multi. But, during 2 hours of prime it generally clocks down to x20. Validation at 4.0....stability testing at 3.8ish.....

I've been reporting my 24/7 clock as 4.0 ghz based on where it runs during Prime95, but I have Turbo on and it generally runs at 4.2 most of the time (including Validation).

Does that mean I have a 4.2 ghz 24/7 clock? That would be pretty cool to claim if it's the convention.

afaik you can permanently enable Turbo with your system. If you are running Vista or Windows 7 though you need to do one more thing in your OS. Under your control panel you will find a setting for Power Options. You need to enable the performance profile or create a custom one. Then look at the hidden options. One of them is CPU Utilization(I think thats what its called, Im at work on an XP machine atm sorry) and you have to set your minimum processor utilization and maximum processor utilization to 100%. Along with certain bios settings that allows me 21x even at idle no matter the temperatures or voltage as long as my current draw is not over 140Amps...so perma turbo mode.

Ok, that's about what I figured but thanks for the clarification. Running up to around 1.45ish vtt is within my personal comfort zone for now. I'm sure I will push past that eventually though and have seen many running higher. They are usually only doing it to run their ram at much higher voltages though whereas I am just working on my BCLKs. I don't have any plans for 2.0v 2000Mhz+ ram myself.

What have you used to test your system? If your temps are ok then it's aaaalllll goooodd. I'm not sure how much you like to read but there are definitely some good articles you can find with a google search. Shoot me a pm if you would like some of my bookmarks.

Actually if you read CPU's i7 920 review they were able to reach 3.8ghz using the stock cooler and with fairly decent settings.

Link please, i7 920 3.8 on the stock cooler = 100C easily. The i7 965 includes a much better stock cooler but he is right though, buying a $1000 i7 965 and running it on air (let alone STOCK BOX COOLER AIR) is a ridiculous waste of money because you are not using the unlocked multiplier to its fullest. You need some fancy water/Phase/Ln2 benching to warrant the purchase of that chip.

Is 100 degrees C not the limit?

They probably didnt stress test that 920. I agree, it would hit 100c easy at that clock.

So as long as the QPI voltage is at 1.35, the max voltage for RAM is 1.85?

It would appear that way from the articles I've read.

[speedy2721]

Where does it say that the qpi and the ram voltage must be .5V within each other?
