Problem overclocking a Q6600.....

Dazzlercee · 29 May 2007 at 21:57

I recently swapped my E6600 for a Q6600 so as to utilise the extra cores in FSX and video encoding etc, etc.

Briefly, my setup is a GB 965P DS4, Q6600, BFG8800GTS 640MB and 4G Geil DDR2 667 Value.

With the E6600 I could easily overclock to 3Ghz buy just increasing the FSB to 333Mhz and everything was fine and stable. Since installing the Q6600 and flashing the BIOS to version F9 (this could be the problem) I cannot overclock by even 1Mhz. The system just doesn't post and resets back to stock speeds. Even if I set the FSB to manual but enter 266 as the FSB it will not POST. It has to be on AUTO.

Has anyone encountered this problem? Could it simply be a bad BIOS?

TIA

I've had the same thing with my q6600, with an abit in9 sli fatal1ty board. I'm no expert at overclocking, so i'm probably doing something wrong, but as soon as i go 1mhz above stock, it won't boot. The motherboard goes into safe mode and I need to reset cmos.

Maybe you need to up the voltage before any raise is possible??

Possibly, I'll give it a try, maybe go to 1.35.

Most boards are having problems overclocking the quads via FSB and the only solution is a hardware mod or buy a later revision board that already have this(GTL) mod implemented.

Above 300 FSB this is an issue but on most boards raising to this is not a problem.

Have you reset the bios to default settings and tried overclocking again?

No, I will give that a go later today.

The quads have a very low default vcore (mine is 1.275v, but I've seen 1.25v). You'll need to raise it for a 3ghz. My 965P DS3 needed 1.425v in BIOS for a stable 3ghz (it vdrooped something shocking).

And the DS4 should be capable of doing atleast a 330mhz FSB, taking you to around that 3ghz mark.

But watch your temps under load.
