Ocing Radeon 9700 Pro


Recommended Posts

ok just got a radeon 9700 pro. already im looking to boost the performance. anyhow what is the best way to OC the crap out of that thing. its not quite like cpu ocing where u just up the fsb. is there a particular program that everyone likes to use to oc is it all done through the bios. oh yeah one more thing what is a safe voltage to pump through that thing i really dont want to juice it too high.

 

 

Rig:

Intel P4 3.0c 800fsb ~-> 3.495 932fsb [Multiplier 15 x 233 @ 1.725v Vcore/2.75v Dimm]

512mb (2x256) Mushkin ddr433 (PC3500) [Vcore 1.725v @ loose timings]

I've got a Radeon 9700pro as well and I am running it a voltage of 1.7 with the memory clocked at 315mhz and the core clocked at 375mhz. The best oc utility I have found is called "Rage 3d" and can be found at the following site, www. rage3d.com

I have done the volt mods too several 9700pros....first thing to remember is that some oc well and some hardly at all.

 

I am running under normal conditions (gaming)....

1.92v vcore

3.19v vddq

1.75v vdd

core=452 mem=364

 

agp aperture set at 32mb (different for each mobo)

agp frequency @ 70mhz

fast writes on

video ram cache disabled

agp8x enabled

agp spread spectrum disabled (important on some nforce 2 boards)

cooling: swiftech mcw50t, large swiftech radiator, acrylic bay resevoir, 4x120mm fans for the radiator, swiftech mcp300 pump, and a dedicated 320watt mean well peltier psu.

 

Here is the info on doing the volt mods....you dont have to use fixed resistors....as a matter of fact I would highly reccomend using variable resistors and set them to the values in the article to start. That way you can adjust them to your liking or to accomodate your cooling. One thing they dont mention is that you cant set your resistor for 1.6v and then use your bios to adjust from there adding 1 v to the bios figure....for some reason this doesnt work. You will also notice that in the article they got their radeon much higher then mine......I dont know how since they are using just h20.....could be variations in the cards.

Dont be impatient and be sure to test step by step only adding voltage when you need to. Stop once in a while to check the temp of your water block or if you use a pelt then carve a spot for a temp sensor in the side of the cold plate. Something else that I have done is to make a bracket to hold 1x80mm fan above the top of the card and below to cool the ram. The ram seems to be held back more by quality then cooling though as I originally used 2x80mm delta big boys and noticed no change from using 2 70mm ys tech magnetic fans other then noise!

Here is that site and let me know how it goes......
