rsnubje Posted March 29, 2014 Share Posted March 29, 2014 I've done these mods too but I have a problem that when I reach 3dmark 11 physics it will go back to 2D voltage and so the system will crash because obviously that voltage cannot handle those clocks. I was wondering if there is a tool or fix to work around this. I have done profiles, but it's far from perfect. Quote Link to comment Share on other sites More sharing options...

rsnubje Posted March 31, 2014 Share Posted March 31, 2014 (edited) I have tried GPU Tweak, Trixx and Afterburner but none of them locks the voltage correctly. Was running not even at 1400 yet, and voltage seems to give me problems above 1.25v. Makes me want to just solder the Epower already. What temps were your coldbugs at? Just for reference.

giorgioprimo Posted March 31, 2014 Share Posted March 31, 2014 did you test the vga single on ln2 ? do you have this problem with both cards ? Quote Link to comment Share on other sites More sharing options...
rsnubje Posted March 31, 2014 Share Posted March 31, 2014 It acted the same with just one card but 1 card would do much lower temps. Quote Link to comment Share on other sites More sharing options...
giorgioprimo Posted April 10, 2014 Share Posted April 10, 2014 same for me .... you need to test mor cards Quote Link to comment Share on other sites More sharing options...
FireKillerGR Posted April 11, 2014 Share Posted April 11, 2014 (edited) Oh just saw your posts, both cards could run @-40C but the sweet spot was @-15~C Edited April 12, 2014 by FireKillerGR Quote Link to comment Share on other sites More sharing options...
rsnubje Posted April 12, 2014 Share Posted April 12, 2014 lol wut? Mine would run at -45 I believe it was but one on its own did -150. Quote Link to comment Share on other sites More sharing options...
FireKillerGR Posted April 12, 2014 Share Posted April 12, 2014 We could run both @-45~ if I remember correctly but the temp on which we were able to play higher was @ -15C Quote Link to comment Share on other sites More sharing options...

FireKillerGR Posted April 13, 2014 Share Posted April 13, 2014 Hmm couldnt agree more Quote Link to comment Share on other sites More sharing options...
rsnubje Posted April 13, 2014 Share Posted April 13, 2014 I'm out for now. Epowered card is working like crap. When I up the voltage just above stock it will crash drivers or not boot even... Probably missing something, but not really my field of expertise. Quote Link to comment Share on other sites More sharing options...
phil Posted April 13, 2014 Author Share Posted April 13, 2014 The card has many protections that are triggered faster(with less voltage) with the use of e-power.They are also triggered with very low temps. Quote Link to comment Share on other sites More sharing options...
FireKillerGR Posted April 13, 2014 Share Posted April 13, 2014 post pics with your epowers to see what you did there Quote Link to comment Share on other sites More sharing options...
rsnubje Posted April 14, 2014 Share Posted April 14, 2014 This is basicly how I did it, simple and easy. I cut off the vGPU IC at the top of the card. I know, the wires should be thicker Quote Link to comment Share on other sites More sharing options...
FireKillerGR Posted April 14, 2014 Share Posted April 14, 2014 Why you cut it? Why you didnt try with it on, without removing it? Quote Link to comment Share on other sites More sharing options...
rsnubje Posted April 14, 2014 Share Posted April 14, 2014 (edited) I did, but even then it wouldnt work with higher voltages. And still learning this stuff Edited April 14, 2014 by rsnubje Quote Link to comment Share on other sites More sharing options...
