Overclocking Q6600 - Some questions

post #1 of 2
Thread Starter 
Hello, it's my first post on this forum, don't know if this is the right section.
Doing my first overclock during these past few days, since I bought the Arctic Freezer 13 Pro CO cooler.
You can check my pc specs but I'll post them anyways Specs 72k .txt file

First of all I gotta tell you that my mb has weird overclocking settings. SPD is configured with a multiplier
not with mhz. So every time I increase the fsb ram mhz increases with it, even when it's on manual SPD.
So whenever you see SPD you multiply it with 400 and you get RAM's mhz.
Also I figured out that my RAM gets a Failing address error (only 1) with Memtest, even at stock timings and cpu fsb.
(But that's irrelevant cause I don't remember having any problems so far with my RAM)

Anyway about my attempts:
System was stable with CPU: 3375ghz (9x375 fsb), 1.325v RAM: SPD 2.4 (960mhz), timings 5-5-5-15.
I ran Prime95 blend test for 8 hours.

Now I managed to get it to 3600 mhz (9x400 fsb), 1.425v with RAM at SPD 2.0 (800mhz), timings 5-5-5-18, +0.2v (2.0v)
and ran a 15min Prime95 stress test with min-max FFT at 4096k. Overclock 3600ghz 722k .jpg file

As you can see my temperatures are no problem and I'm also gonna lower the voltage when I finally stabilize my system.

To my questions,
Since I can't run any memtest cause my RAM is causing an error what test should I run with Prime95
or any other program to see if my overall system is stable?
When I increase the fsb and RAM's timings and SPD are at stock settings manually, why do I have to increase my RAM's voltage as well to stabilize my system during Prime95? Since it's at stock settings shouldn't it work properly no matter what the fsb is?

Try having a look at this guide: OC Guide.

I know it says Core 2 duo and below only, but it will give you the general idea. Plus there is little difference between the quad and the duo in terms of which settings to change.
