Overclocking Q9300 without it dieing in 6 months


Jan 11, 2009
Hello, I would love to over clock my q9300 to about 3.0 or 3.1. I really wouldn't like for the cpu to die within 6 months like most do.

These are my system specs

ASUS p5q3 P45 intel 1600FSB
Blue Orb 2 cpu cooler w/ artic silver 5
DDR3 2gb @1333
Thermaltech 650x psu
antec 9 with 4 120mm fans and one 200mm on top

I've overclocked my last system before but i did it with AI tweaker from asus. Should i use this program again for my new set up? Also i dont mean to sound like a n00b (i am when it comes to overclocking) but i dont understand the math behind overclocking. Is there a thread that explains it?

I read http://www.tomshardware.com/forum/246923-29-overclocking-q9300-long-term and i dont understand the math there. Maybe im just dumb lol. Well i understand the math just not the reason behind it.

Thanks, sorry for the ignorance :)

If you want to be safe, just go as high as you can (stable of course) at stock voltage. The Q9300 should be able to hit 3.2Ghz on stock voltage. They overclock very easily to a certain point while staying cool. The barrier with these is more the low multiplier, which means you have to really push the FSB if you want really high OC's.

But for what you want, you should be fine and safe.

I run my system as below:

Asus P5K3 Deluxe | Q9300 @ 3.5Ghz - Scythe Ninja Cu | ATI 4870 512MB
2GB OCZ DDR3 1333 @ 1400Mhz | 2 OCZ 30GB CoreV2 SSD (RAID 0)
850W BeQuiet! | Antec 900 | 32 Bit Vista Ultimate | 16,178 3DMarks06

Have had it running like this for a few months now, no problems. I now have created a new underclocked setting in the bios for day to day use i.e. office and web browsing.

Works a treat.
All settings adjusted in the bios, not an Windows tool. Read the threads, I really only had to change the multiplier, fsb frequency and core voltage to get it working nicely.
