Radeon 9800pro overclocking

[rcecola]

My max overclock(stable) on my ati 9800 pro with stock cpu cooling and iceberq ramsinks is 403.31core and 364.5mem at 22c ambient, 38 system, 52 cpu. does anyone have any advice on how to overclock my 9800 to higher levels with stock cooling or is this all that is possible?

Better case cooling will help, to have a system temp of 38 is fairly high. You can replace the thermal adhesive on the heatsink with something better like artic silver 5. There the main two things you can do to start with, theres a lot more but if you wanna keep the stock cooling then there a good place to start.

btw those clocks are fairly low so you should be able to get some more out of the card

how much more can i get from the card?
what are typical numbers i can expect from overclocking with stock cooling?

with stock cooling i got 440/380 but i was quite lucky, it is always luck of the draw but you should be able to push another 15-20 out of the core and maybe another 5-10 out of the ram with better air flow and better thermal goupe.

you could try to up the voltage to you AGP slot . I had a liquid cooler on my GPU and got it to 435/380 and now I have the zalman HSF dule heatpipe cooler on it, ( the liquid cooler quit on me. ) and I can only eek out 424/370 with over volting the slot to 1.6v but my system still says it is at 1.48v on the AGP +1.5V. your temps are ok as far as the system temp mine is runing around 38-40c my CPU is O/C'ed to 2.5 Ghz and it is at 39c no more than 45 under full load .

i currently have the agp at 1.6v, i can change the agp voltage to 1.7v but i only have a 350w psu. can the card and psu handle 1.7v without any problems?

[trickson]

yes that is plenty of power to do the job..

[fr33ze]

as trickson said thats plenty of power but setting it to 1.6/1.7v is not feeding the core or memory with more voltage at all so it won't result in an improved overclock, if it does it'll be very marginal.
