EVGA EPower-Board Test 2 (8500 GT)

[der8auer]

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

So the result depends quite much on the card you use. :)

[Sam OCX]

looks much better on PWM-limited cards

[Antinomy]

Especially if the memory was indeed run at default in the first test.

[Massman]

Hm, looking better indeed.

[der8auer]

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.

[El Gappo]

Curious as to what these will do on something like a ref 580.

[der8auer]

Would test if I had one but too much money just to buy one to mod :D

[Massman]

I still have this GTX275 Lightning that needs a fresh PWM. Shall I bring it to CeBIT ? :)

[der8auer]

Yeah sounds good :)

[fuzz3l]

Nice testing Roman!

This will be your approx 10th 275 Lightning, huh?

[der8auer]

close - 9th :D Still have 3 here =)

[reggiesanchez]

thanks for sharing your results. I have one question though. Is grinding down your card essential for good results. Have you tried without it??

[der8auer]

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]

Are grounds from original 6 pin still ok to use?

[Hondacity]

yes

[der8auer]

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.
