How to Overclock 2 9800GX2's?

post #1 of 26
Thread Starter 
Hi peeps.

Could any one help me overclock my system? GPU in paticular?.. I have a quad SLI set up with 2x BFG 9800 GX2's all running at stock, Just installed a new EK water set up on a secondary water cooling system for the GPU's so I can afford some extra heat!- core 600Mhz - Shader 1512Mhz - Memory Clock - 1000Mhz.
Also my primary water coolong system is cooling my Q6600 @3.0Ghz, was hoping i could squeeze some more speed out of that? or if any one has a Q6600 Running any higher, could you share your settings with me? My Specs Below:

Q6600 @3.0Ghz (primary Swiftech 220 Water Cooler)
2x BFG 9800GX2's (secondary Swiftech 220 Water Cooler)
XFX 790i Ultra MB
OCZ Platinum (4Gb) 1800 (running 133Mhz to match FSB)
1KW Cooler master PSU

Thanks in advance

Got that thanks. Do you know roughly what to set the MEM/SHAD/CORE frequencies to?

Just start pushing the core until you hit instability, then back it off a bit and work on the shaders, finally, work on the memory. It's all trial and error.

Hey I also own gx2 and q6600
Just for reference my q6600 is at 3.2 ghz on stock cooling... so you should be able to go crazy.
My settings for the q6600 are quite simple really, stock voltage, stock multiplier (9), and frequency at 355.
I idle mid 40's C and peak at 55 C, no higher.
Hope this helps.

You could, but I have a totally different BIOS than you so it might be hard. I'll post them anyway.

I highly doubt you're only loading in the mid 50's under a full load with that stock cooler and that overclock.

gotta believe it, ABSOLUTE highest I've ever seen it is 57 C after 13 hours of L4D. I have this baby in a 1200 so maybe that's why
