Intel core 2 quad q9300 driver update#

It is extremely unlikely that your windows installation was damaged due to the overclock. Your memory wasn't stable at 1125 MHz OC. For best performance ing games you will probably need to get up to 3.6 GHz and above.

This means you will need to update your BIOS first. Note: BEFORE you apply the above, MAKE SURE you are running the LATEST BIOS from ASUS (2301 ). 1.25) (This setting is auto set by the board) Try the following settings, and leave anything not mentioned here to AUTO.ĭRAM FREQ: 1125 (FSB RAM 4:5 i.e. You are lucky you are using the same mobo with me. If I knew back when I bought my P5Q Deluxe what I know now about OC'ing Socket 775 45nm CPUs, I'd buy an X48 board and DDR3. Overall, the P5Q Deluxe is a very good and very solid board for overclocking (definitely better than Gigabyte boards), however, the best performer for Socket 775 is defo X48, then X38 then P45. I did not need to do over 450 MHz as my QX 9650 is unlocked, and I did 4.2 GHz with a 10X multiplier and a mere 420 MHz bus speed.īus speeds above 480 MHz require very high PLL voltages which I am not sure if they are safe for 24/7. The max I have taken the P5Q deluxe (which I am still using) is 450 MHz bus speed. For that to be doable, you'd either need to use a lower divider than 4:5 or OC your sticks to 1200 MHz or buy DDR2 memory rated for 1200 MHz. Your absolute maximum limit will probably be 480 Bus Speed X7.5= 3600 MHz. That's a hard overclock but it is probably doable with only two sticks. Your memory needs to be able to achieve a stable overclock of 450X1.25=562.5X2=1125 MHz (4:5 divider). IMO, your max overclock will be 450X7.5=3375 MHz

You are confusing the Bus Speed with the memory speed.
