Splave Posted December 29, 2013 Posted December 29, 2013 It's easy! I will be doing one next week will take pics. Quote
dinos22 Posted December 29, 2013 Posted December 29, 2013 Splave, don't mod it yet man. These cards have a different design. Amd needs to come through with a special bios that ignores signal from controller to core Quote
steponz Posted December 29, 2013 Posted December 29, 2013 That's what I thought.. i was itching to do it also... think it will happen at all? Pretty disappointing Quote
dinos22 Posted December 29, 2013 Posted December 29, 2013 We're trying to get it from AMD. I'll share it if we get it Quote

dinos22 Posted December 29, 2013 Posted December 29, 2013 Can't just remove controller? Â Not with these from what I was told Quote
Massman Posted December 29, 2013 Posted December 29, 2013 Yeah, there's a feedback loop from PWM to GPU to check the current (for protection). If you cut the PWM, the feedback loop is broken, and the GPU won't work. Quote
Splave Posted December 29, 2013 Posted December 29, 2013 Amd trolling us! Lol maybe waiting for custom PCB is best Quote

dinos22 Posted January 3, 2014 Posted January 3, 2014 I got some info via the IR engineer and it seems the R9-290X is using the new VRM Design. It uses SVID just like the new CPU VRM spec, and epower board is using the old VRM. The bottom line is that the EVGA Epower board can't support R9-290X. There is basically no way to make it run as the power board has no SVID Signal! We are going to make some power boards that support these 290X cards Quote
der8auer Posted January 3, 2014 Author Posted January 3, 2014 Dino you're the man! Looking forward to a new G-Power. Quote
steponz Posted January 3, 2014 Posted January 3, 2014 Going to be interesting to see when the msi lightning version comes out... Quote

I did try to feed a AMD 290X with Epower.... so, we had problems with 1.8 line voltage... Then we installed one more zombie... and have problems with PLL voltage... Finally we used one more zombie (3 zombies)... and even with 3 external power to feed... was impossible to use the zombie... Also... is good to remember that we have 2 Vready in the PWM... and we try with 1 and 2 PWM disabled... and even we removed the PWM it not works... About 30 hours trying with no sucess... So... we used normal hardmodding https://www.facebook.com/media/set/?set=a.559801364095137.1073741879.290467317695211&type=1  Pay attention on the inductors... is not in line.,.. lol .... I put it again and never will be uniform libe brand new; Quote

Yes, you do need to take care of fooling stock PWM controller signals, to make sure other power convertors and GPU get proper signals first, BEFORE using EVGA EPower for GPU power.  For extreme OC we usually don't want GPU controlling our voltages (disregarding if it goes from stock VRM, or external VRM), which is reason of SVID interface there. Lack of knowledge to properly mod card does not mean it cannot work But anyway, let's see other VRM board with SVID working on 290X first. Having SVID will still do nothing, was there , done that before  Rbuass run into power sequence/powergood issues after he disabled VGPU stock PWM controller, which is clearly the reason why he had no voltage on those secondary rails. Please don't mix different issues together.  If anybody want - get me 290/290X and I'll post modding guide, lol Yes, education is expensive Edited January 4, 2014 by TiN Quote

Send please your shipping details by PM and I will send you the R9 290X... I believe nowadays, you are the only in the OC community that can do that zombie works on 290X.  Edited January 4, 2014 by rbuass Quote
steponz Posted January 4, 2014 Posted January 4, 2014 I can send if needed.. will just have to wait til I get back from vegas. Quote
TiN Posted January 5, 2014 Posted January 5, 2014 Rbuass, u got the message I'll mod it, shoot guide, maybe small video running FSE, then remove epower and send back. If anything happens - not my fault Quote
FireKillerGR Posted January 5, 2014 Posted January 5, 2014 (edited) I am in to donate on Tin's effort cause I couldnt send him a 290x to find the mods ^^ Edited January 11, 2014 by FireKillerGR Quote
