Overclocking my qx9650 - Page 2

post #11 of 16
Will post some info soon - I've got extensive logs of testing my QX9650 on an Asus P5P43TD/USB3.

DRAM @ ~1.5V (Whatever My Ram Voltage is)
FSB @ ?
FSB is the only one I do not know.
Then, in terms of overclocking, I simply up the multiplier, make sure for POST, and run Prime95 Blend.
If BSOD, then up which of the voltages? Just the CPU?
I appreciate the help with the voltages! Lot of missing information based on the ever increasing rapid change of technology lol

Use the Equation... FSB x Multiplier = Core speed.
So for example an FSB of 450 x Multiplier of 8.5 = 3825 (or 3.825 Ghz)
Then if you do not post you Up the Vcore a little. If your Vcore is too high and still no post you can try to raise the VTT a little. If still no post try a different clock and Multi and start the voltages over.

When you do post that is when you test for stability and try to lower the voltages to find where the chip uses the least amount of power and is still stable.

Since your chip is not multiplier locked you could do FSB 400 x Multi 10 = 4.0 Ghz.

Ok so my FSB is currentely 333MHz then a 9 multi. So your saying I should go for 400 FSB and 10 multiplier right off the bat and check for POST? Then if no POST, up VCore and what not until POST.

If the VCore is too high, such as hitting the max volts for the chip, I up the VTT voltage?

Is this basically what I should try?

Thanks again for all of the help!

Basically yea... I wouldn't hit the max voltage for the chip before trying a different setting though.
Do it in stages. Hit 3.6 - then 3.8 - then 3.9 - then 4.0.
Or go for 4.0 and start down.

Just don't sit on a high voltage for very long.
If you can post at 4.0 with 1.35 volts, then I'd immediately shut down and try for 1.3 volts... etc...
Once you find the min voltage to POST at 4.0 then start stress testing for stability.

Always check temps.

So in the case of starting low, should I leave the FSB at 333MHz or bump it to 400MHz with a low multi?

Up to you, you have an unlocked multiplier so you have tons of options. This is the fun part, experimenting with different settings.
A high bus but low multipler could have different performance results to a low bus high multiplier.

If you google enough there are tons of trials involving different ways to hit overclocks and how effetive they are.
With a locked multiplier it is way more strict.
