OCing 9800GX2?

[bloodline76]

Anyone have a 9800Gx2 and is it safe to overclock with the high tempts?

I have mine at stock at the moment and wondering how high people have got theirs without roasting their legs.

Thanks

My speeds show:

Core: 600
Shader Clock: 1500
Memory: 1000

what are your temps, if at load they are under around 85 or so you should be fine, my 6800 has been running @ 90 load for 3 years now

Runs at 70 on load (That is with fan turned up to a liveable noise). What would you increase if you were going to overclock?

well, the memory is usually the one that pushes more heat with bigger overclocks, so i would be a bit more conservative with that, concentrate on core and shaders a bit more than mem

 

[bloodline76]

Put it up to:

Core: 650
Shader Clock: 1550
Memory: 1000

See how that goes

if your temps are good, knock the mem up a bit

What is the best tester for stability and temp for graphics cards?

for temp, most monitors such as gpu-z will be fine, for stability run a benchmark like 3dmark or crysis and if there are any glitches or slowdowns or crashing then lower the most recent overclock

I know that all cards are different but what sort of range can you expect for the core, shaders and mem?

Like core usually goes from 600 to 750

What are considered the higher ends of the scale for each

Mine can bench and fold at 745/1862/1050 core/shader/mem.

But when playing games I lower it to 730/1825/1025. With the fan at max both cores go upto about 90C during a warm day when playing crysis. I do have AS5 applied and the metal case taken off though.

Considering both cores are sharing the same heatsink I'll say mine is an average oc, but a single core 8800GTS/9800GTX/+ are known to overclock to 800Mhz+
