Tijd voor die nieuwe cpu

Woa, that board really rocks! Great score!

Gratz! What kind of weird version cards are those?

 

[EDIT] Just realised the connectors are not AMD:P GTX 780 Ti's they are.

[GTX 580 LIGHTNING]

For the card I have, colder wasnt better. Might be worth it to try -50ish.

Thanks PJ How is the Haswell usage compared to Ivy, like in the 2nd picture.

Thanks Phil, apearently I need to get some more epowers

[Haswell LGA1150 Z87 OC Tools, BIOS, facts, stats and list of mainboards]

Im curious in what 3D benchmark Haswell is most populair against other 3D benchmarks and maybe Haswell vs Ivy

[phil - 2x Radeon R7 240 @ 1620/1500MHz - 8977 marks 3DMark11 - Performance]

Wow, nice Phil! Care to post pics of cards with epower?

[phil - 2x Radeon R7 240 @ 1520/1480MHz - 8503 marks 3DMark11 - Performance]

Nice run Phil! Maybe after the cup you can share epower mods?

Nice one Moosie

Was probably for his previous score

vGPU and vMEM were 1.51v and 1.63v as far as I know.

[Sapphire R7 240 1gb vgpu and vmem mods.]

Thanks for the tips so far

 

[EDIT] Still crap, 1 card on its own does 1.2v but when together I have to lower it. Any safety features you disabled? Im at the point I want to throw them in the carbage bin

[Sapphire R7 240 1gb vgpu and vmem mods.]

Ye I have another epower, v2 If all works well then I will go for it! Still amazed how far dancop came tho.

[Sapphire R7 240 1gb vgpu and vmem mods.]

I've switched ground this morning and ran one test with Epower v1 on stock voltage(1.2v) and no problems with booting and I could easily run a benchmark. Last time I tried with 1.2v it wouldn't even boot or run a benchmark. I brought the wrong evbot with me so couldn't test higher. More testing later today.

[Sapphire R7 240 1gb vgpu and vmem mods.]

Well the card still runs but only with low voltage. I will try real ground tomorrow.

[Sapphire R7 240 1gb vgpu and vmem mods.]

Worth a shot. Really must have been sleeping by not even measuring if its ground... Thanks for the heads up.

[Sapphire R7 240 1gb vgpu and vmem mods.]

I did, but even then it wouldnt work with higher voltages. And still learning this stuff

[Sapphire R7 240 1gb vgpu and vmem mods.]

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

 

[Sapphire R7 240 1gb vgpu and vmem mods.]

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.

Not really Dripping icecream?

[Sapphire R7 240 1gb vgpu and vmem mods.]

Nice swimming pool you must have had.

[Sapphire R7 240 1gb vgpu and vmem mods.]

lol wut? Mine would run at -45 I believe it was but one on its own did -150.
