my first try, What can I expect?

[Hitch Itch]

Im finally going to try to oc my comp.
I have no idea how to do it.
My system is getting a little old and I want to keep it for another 6 months

Which guide should I use?, ( need a guide for oc dumb dumb's)

How much improvement can I expect? (what % improvements have others seen with my spec parts)?

Any extra tips that I should watch out for?

my spec's:
EVGA 680I mobo
Intel X6800 extreme core 2 cpu
2x XFX 8800 gts 512 meg gpu's in SLI
CORSAIR DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) (with cooling fan)
Western Digital Raptor 150 gig hard drive
PC Power & Cooling S75CF 750W EPS12V SLI NVIDIA SLI Certified
Coolermaster Aquagate mini r80 cpu water cooler

I ordered a new case, COOLER MASTER NV 690 NV-690C
It will be here soon, my current case is worthless for airflow

tx for help/tips

this oc dumb dumb needs all the help he can get, I dont want to let the smoke Yet

You should probably read graysky's sticky. I'm going to say you can reasonanly hit somewhere in the range of 3.5-3.8ghz with the x6800.

go into your bios and change your X6800's multiplier (CPU clock Multiplier). 11 to 13 would give you a 3.7ghz processor. Watch your temps & it's going to take more CPU voltage

Your 8800gts 512's can be overclocked to their limits (temps / game crashes). you can use a memory divider and vdimm control in bios to make your memory run at around ~550mhz and/or get better timings.

If you don't understand this stuff - read a guide or two to get the OC'ing basics down.
