I might possible need to help a friend out overclocking his Intel Quad Core Q9550. How high is a safe clock on air.

Also if anyone could tell me settings that need to be modified in bios (volts. changing timings on memory. ect.) I'd be really thankful.

At the moment I was hoping to get it up to 3.89GHz (about 448x8.5) @ 1.35000 Vcore, how does that sound? And if I would, do I have to fix the timings and can it run like that on air?

+ Rep for you my friend!

But what type of cooling did you have, and would there be many changes compared to your setup if I wanted to run the CPU @ 3.8GHz? Also he's got 800MHz memory chips. Couldn't I simply higher up the timings to 6-6-6-18 and run it @ 900MHz-1066?

-- PS. ---

If there are more people out there that would like to share their setup, please do.

freakb18c1

cooling on that setup was a tuniq tower 120 pc6400 can easily go 942mhz with like 1.9v set the ram to standard to give you some head room

daanielin

The runiq tower 120 is of course huge. Not sure if V8 is as good cooling..

And tell me, I could not use the exactly same setup that you used with the pc2-6400 memory could I? If not, than you know what I could do to be closed to it?

[Teh Root]

Oh gawd. Try to epxplain t=ahlf the things on your reference sheet.D o you really need all of those things disabled and enabled and is your BIOS even typical?

you def can.i have used pc6400 and almost hot 1130mhz with out going past 2.2v trust me your good.

edit the v8 is better then Tuniq tower

Aight thanks a lot mate, I'll try it tonight, I'll report how it goes.
