Gigabyte Q9550 overclocking

post #1 of 4
Thread Starter 
I have the Gigabyte EP43-DS2L motherboard and the Q9550 Quad. I -cannot- get my FSB over 419MHz. Setting it to 420MHz causes the system not to boot. Changing ANY voltage higher does nothing. Setting the DRAM multiplier to bring the memory speed down does nothing. I can't seem to get it clocked higher doing anything.

Any help?

Below are my current settings.

Multiplier 8.5x
CPU FSB 419MHz
PCI E Frequency 100MHz
DRAM Multi Auto

Voltages
Vcore 1.28v
Term 1.3v
PLL 1.650v
MCH 1.2v
ICH 1.65v
DRAM 1.9v

Hey CorporalAris!

The P43 boards have been known to have an FSB wall between 400-420 depending on the type of motherboard you have. For my old p43 when I was still rocking my Q6600 it was 400, so you actually have a better board than what I had.

Here's a thread I made on how to break through that fsb wall.

How to overcome the P43 fsb wall

I hope it helps you in anyway! Also I hope you're only using a couple of the ram slots since that does limit your OC as well, specifically in 775 boards.

Thanks! I am using 4 slots (for 8gb, i could upgrade)

I'll give this a shot, but I may just go hunting for a p45 chipset instead....

If you can find cheap P45 boards, that's definitely the best option!

Good luck!
