Hi all,

after some request from some fellow overclockers,here are the basic mods for the Sapphire R7 240 1Gb GDDR5 card.Have fun :celebration:

 

 

 

 

 

Thank you for sharing Phil ,nice gesture.

thanks,

 

anybody could also indicate the Vgpu and Vmem reading point ?

Here you go Giorgio

 

Awesome, thanks for sharing Phil!!

great, thanks

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.

What voltage/clocks/overclocking utility ?

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.

did you test the vga single on ln2 ? do you have this problem with both cards ?

It acted the same with just one card but 1 card would do much lower temps.

same for me .... you need to test mor cards

Oh just saw your posts, both cards could run @-40C but the sweet spot was @-15~C

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

We could run both @-45~ if I remember correctly but the temp on which we were able to play higher was @ -15C

Nice swimming pool you must have had.

Can you think anything better that this with this weather?

Not really Dripping icecream?

Hmm couldnt agree more

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.

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.

post pics with your epowers to see what you did there

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

 

Why you cut it? Why you didnt try with it on, without removing it?

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