This is my first thread here, please tell me if I opened it somewhere wrong. I have the following specs;
Asus P5Q Pro- Q9400
2gb*2 DDR2 800 Ram
1gb*2 DDR2 800 Ram
Very old PSU, it is 350W
I am browsing the web for almost 4 days, read lots of overclocking guides and some examples for q9400 or for p5q pro I can give links to every page-thread but it would be so long, for example;
I am stable with these settings;
PCIE FREQ: 100
FSB STRAP TO NB: Auto
DRAM FREQ: ddr2-831 mhz
Dram timing auto or manual (5-5-5-15)
DRAM STATIC READ CTRL: DISABLED
DRAM READ TRAINING: DISABLED
MEM OC CHARGER: ENABLED
AI CLOCK TWISTER: LIGHTER
AI TRANSACTION BOOSTER: AUTO
FSB termination 1.36
CPU and PCIE spread:disabled
CPU and NB Skew:Normal
CPU Margin: Performance mode
My question is how much PSU would be effecting my overclock stability? If I increase nb to stabilize with 425 fsb, psu or motherboard(don't know which one) starts to make some kind of an electrical sound like this one;
Is it because my psu is so bad(btw I dont wish to continue with that psu anyway because it is 350w and so old, I bought a brand new 650w thermaltake smartpower 80plus bronze) or is this buzzing because my motherboard and cpu does not need that much volt?
Is it possible to achieve better overclocking with better psu? (I am not thinking 650w vs 350w would make the effect but the quality of the psu)
Is 2.66 to 3.32 roughly what should I expect from my q9400 or should I expect more from my cpu as a beginner?
As I learn (correct me if I am wrong) 1.37500 as vcore is too much and cpu-z shows it as 1.36v with vdroop. but anything less, causes unstability. Does it mean my cpu is somewhat not that good and that is why it needs so much vcore? What about my other voltages? I tried to keep them all low.
Any suggestion, help, answer would be so appreciated.
