der8auer Posted February 23, 2012 Share Posted February 23, 2012 Hi there Just tested the EPower Board on my 8500 GT after the 8800GT didn't realy scale. Result with stock VRM at 1,8 ± 0,2 vGPU: 1026 MHz Powered by EPower Board I could reach 1107 MHz. 81 MHz more than with stock VRM which means total overclocking of 141%. Voltage was 1,81 vGPU Pics of the Mod: Mod done: So the result depends quite much on the card you use. Quote Link to comment Share on other sites More sharing options...
TaPaKaH Posted February 24, 2012 Share Posted February 24, 2012 looks much better on PWM-limited cards Quote Link to comment Share on other sites More sharing options...
Crew Antinomy Posted February 24, 2012 Crew Share Posted February 24, 2012 Especially if the memory was indeed run at default in the first test. Quote Link to comment Share on other sites More sharing options...
Massman Posted February 24, 2012 Share Posted February 24, 2012 Hm, looking better indeed. Quote Link to comment Share on other sites More sharing options...
der8auer Posted February 24, 2012 Author Share Posted February 24, 2012 Especially if the memory was indeed run at default in the first test. yep was default. I only did a vMod for the GPU for the first test. So left memory on stock. Quote Link to comment Share on other sites More sharing options...
El Gappo Posted February 24, 2012 Share Posted February 24, 2012 Curious as to what these will do on something like a ref 580. Quote Link to comment Share on other sites More sharing options...
der8auer Posted February 24, 2012 Author Share Posted February 24, 2012 Would test if I had one but too much money just to buy one to mod Quote Link to comment Share on other sites More sharing options...
Massman Posted February 24, 2012 Share Posted February 24, 2012 I still have this GTX275 Lightning that needs a fresh PWM. Shall I bring it to CeBIT ? Quote Link to comment Share on other sites More sharing options...

reggiesanchez Posted February 25, 2012 Share Posted February 25, 2012 thanks for sharing your results. I have one question though. Is grinding down your card essential for good results. Have you tried without it?? Quote Link to comment Share on other sites More sharing options...
der8auer Posted February 25, 2012 Author Share Posted February 25, 2012 Not if you find enough ground spots. Ofc it's possible without grinding but the more ground wires you add the better the result will be. I just did it to be safe and actually the card is done anyway after applying the Board on it.

reggiesanchez Posted February 26, 2012 Share Posted February 26, 2012 Are grounds from original 6 pin still ok to use? Quote Link to comment Share on other sites More sharing options...
Hondacity Posted February 26, 2012 Share Posted February 26, 2012 yes Quote Link to comment Share on other sites More sharing options...
der8auer Posted February 26, 2012 Author Share Posted February 26, 2012 Are grounds from original 6 pin still ok to use? Yea but the 8500GT doesn't have a 6 Pin connector. If you use a different card like 8800GT you can use the 6 Pin connector of course. Quote Link to comment Share on other sites More sharing options...
