Cannot overclock Q9550 on Gigabyte P965-DS3 Motherboard...

[kvanryn]

If I up the FSB on the F13 BIOS on this motherboard, my Q9550 C1 stepping processor will not work. I set the BIOS FSB to 400 and save and when it starts to boot, it just resets itself and goes back to defaults.

That chipset was orginally made to support 1066 FSB cpus (FSB 266). Giga gives support for the 1333FSB cpus (FSB333). In order to overclock you need to raise the FSB up a little at a time. Do not just push it all the way up to 400FSB.

I have tried pushing the FSB setting alone a little bit up, save the settings and when it reboots, it just reboots and loads the defaults. Any idea why this might be happening?

Maybe your board is at it's limit at 333 fsb? Try using 340 and go up in steps of 5.

I am beginning to think it is a motherboard issue. If I move it up 5, it will not boot. So, I will upgrade the board in time. I will just use it at its present freq. Thanks for the update!

What revision of the board do you have? Rev. 3.3 has unoffical support for that processor with F14b bios. I just upgraded from a Rev. 3.3 and had no problems overclocking my old ( offically supported ) E6600 to 400fsb with a Zerotherm Nirvana for cooling and 2 gigs of Corsair DDR2-800.

According to the Gigabyte website, they suggest F13 BIOS for the Q9550 C1 stepping processor. I have tried both the F13 and the F14b and neither will allow me to up the FSB and have the system boot to the higher speed. It just resets itself to the original settings...I just can't seem to overclock the processor. Any other ideas out there? Thank you.

Get a board that has a chipset that officially supports the cpu. I have the same board but I dont have a non officially supported cpu.

Did you follow the other overclocking settings properly for the board. Proper ram settings, lock the pci to 100. Thats basically all there is to it really anyways.
