Hi people
Against every sane nerve in my body, I decided to upgrade my cpu (then a 2.8Ghz E6300 @3.675Ghz on stock volts) to a Q9650.
It is mainly used for encoding. Anyway, I got the chip and started OCing it, I never go past stock voltage (ever!). I planned use the chip to break the 4GHz barrier.
I set the FSB to 400MHz straight away which got me 3.6Ghz and passed IBT so I continued. Next I tried 450MHz for 4GHz, my pc didn't boot. Lowered to 440, still didnt boot. I kept lowering it until it got to 410, finally it booted and passed IBT on maximum.
I tried 415MHz and my PC didn't boot so I raised the voltage to 1.3V, still no boot. I then came accross a review of my mobo, stating that the FSB was limited to 410MHz
.
Getting a new mobo is out of the question because spending ~£90 for an extra 400MHz on the cpu seems a waste (so was getting the cpu but anyway), also cannot be bothered to do a clean install. So I decided to make the most of what I had. Also I don't plan anymore upgrades for at least the next 3 years.
I lowered the FSB to 400MHz to play it safe and started undervolting the chip. I was astonished with the results bearing in mind I am only using the stuff in my sig:
Q9650@ 3.6GHz|Win 7 Pro
Corsair 2X2GB PC6400 XMS2 Pro|Akasa Nero|
Gigabyte GA-P43-ES3G|Gainward Radeon 4870 1GB GS
Antec TruePowerNew 650W|NZXT Tempest|500GB Samsung F1
Look at the voltage! Now I have to live with not being able to untap the full potential of the chip
