CHeck THIS out. I believe this is the issue:

There are 2 versions of this particular power supply.
SS-1250XM (mine)
SS-1250XM2 (DocstakeDooty's and XFX1250 OEM)

The design on one side of the PSUs are different:
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 95

And they come with different cable combinations (slightly)
Mine is the 1250xm version not xm2. I didn't have a problem with instant reboots either until I ran 4k. As soon as I hooked up my 4k monitor is when it started tripping ocp. In fact one if the stock pcie connectors that plugs into the psu melted which could have turned out pretty badly. When I gamed on 1440p it never tripped the ocp and I have never ran my 295x2 oced always ran it at stock clocks and volts.

I am a ek fan myself. I think they should perform about the same. I do have the ek nickel block myself and I do recommend you buy the ek backplate as they give you more thermal pads that unlike my 780ti classy or 780 they cover alot more of the hot spots on the back. The nickel plating used to be a issue with ek but they changed there nickel plating manufacturing so there is not the problem of flaking like there used to be. The nickel is again just more for looks anyways. As far as the blocks go performance wise should be about equal just depends on which style you like better.

They main problem with 295x2 is still the VRMs even with full cover waterblocks. If you overclock hard the vrm will still be hot. core temps will be the same for those blocks but 290x cards aquacomputer ones have -20c lead for vrms.

i have a nickel AC brand new in box that needs a new home. also i have the active cooling backplate which may improve vrm cooling a little more
post #3776 of 9133
does the 295x2 give 4 or 8go of usable memory? i know that two r9 290x in crossfire dliver 4go of uable memory but i saw some people talk about 8go of ram in the 295x2

All 8GB of VRAM is usable, but it's only 4GB VRAM totaled that is mirrored onto another set of 4GB VRAM.

so basically, is there any difference in cooling VRM's between EK and AqCo ? If im buying i wanna make sure im buying hte best smile.gif

Yeah that was a long time ago(2011 i think) and now its okay. Also if U dont use silver coil its all okay.
I will deffo buy a backplate on this one smile.gif


Still waiting for someone with Asus 295x2 Ares bios(for both gpus). Anyone? smile.gif
post #3779 of 9133
I avoided the aquacomputer block because the active backplate for the 295X2 didn't exist and I wasn't about to leave the backside uncooled at all so I just went with the EK nickel block. Then there was some rumor about something being wrong with the aquacomputer block so I didn't feel like finding out firsthand if it was BS or true.
post #3780 of 9133
Does anyone know what the best deal on one of these is? I would like to buy 2 and put a W.B. on them.
