Also in GPU-Z it shows that is has 2816 shaders. Here the the GPU-z. Anyone have any idea whats going on? Could it actually be a 390? Should I try and send it back? Thanks guys.


They are all like that. It says 390 series.

The voltage is .05mv higher than my 290x. Its a standard number as I recall, though I cannot remember what. I'll have to check that... Modified EK block that was meant for an XFX 290x. Remodeled to allow the taller caps.

Something's weird here for sure...

Okay, here's the screeny.

And here I bumped it up to 1250mhz just to see if it would hold. I have my doubts that it could make it through a bench run on this though. If I can get the temps down more though I would bet it could make it. But VRM1 is just getting too hot right now.



Edit:

This makes me wonder if there's a small difference in the RAM height from the older 290x on this block? Or something else that's keeping it from making good contact. I did notice the board seems to be warped ever so slightly. Which seems odd. Its the whole thing, back plate included. Hmmm...

Edit2: Well, this was an experiment I wanted to try... but I don't think its working out. I think I ruined the block. LOL biggrin.gif

Edit3: These 390X cards are beasts, but dang do they crank out the voltage. I think it was mentioned somewhere that they run higher volts to allow the base clock of 1500 on the RAM. I may be mistaken, but this really translates into some serious heat. Heat the 290 series was already known for, but the 390 series really takes this to a new level. Interestingly the core is easy enough to tame. My 390X is running identical to the 290X, so no difference there. The VRM's though are hotter, at least on my setup they are.

Must be something wrong considering I'm getting 75C max temps on a Alphacool GPX block (Hybrid, core is watercooled, VRM is not) on the VRM1. And that is with +175mV.

Dang... yeah, I'd say something is wrong for sure then. Thanks!! thumb.gif

Edit: I might have to get a pair of those blocks then...

Pff damn the dual PSU adapter is expensive and I'm struggling atm.
I just want to run for a few hours 2x 390 on my PC to do some benchmarks for my review site and YouTube channel..
Is there any way I can do it without the adapter? I will be running only 1 GPU and I'll sell the other one afterwards.. What do you suggest me?

Use a paper clip between the green wire and a black wire on that 24pin PSU cable. That will turn it on. Then you can do what you want.

Jump the green wire and the black wire on one 24 pin to the other 24 pin. This can be ANY black wire since the blacks are all grounds. Just strip a bit of wire away. I ran miners with 2 PSU's wired this way for months.

Excuse me, can you link me to the exact thermal pads you've bought?? what size am I suppose to buy??
