And that's why I'd never touch Crossfire again with a barge pole.
Until somebody can think of a way of making MGPU work with having to code specifically for it then it's always going to be a pain in the whotsit.

The best thing for MGPU, would be MGPU in the consoles.

Matt, any chance you could explain this:
I know it's mixed, but that still shouldn't be anywhere like this.
Theres definitely something up there, as Crossfire isn't that good

If I remember it right several regulars here were claiming the X box Scorpio was going mgpu last year.

heres something interesting on the new driver. It would seem that any more than 1200mv and my PC locks up whenever I start any 3d application. I can even drop my clocks right down to under 1700mhz and it'll still lock up. Once I drop under 1200mv, complete stability again. Back on the .9.1 driver and I can run 1800mhz and 1230mv again just fine.
Built my full loop this past weekend with my 64 Air card. I haven't done much tweaking since I've been busy this week, but I flashed the LC bios. The card would crash at stock LC bios clocks so I dropped p7 down to 1702 with stock voltages until I have time to work out the best settings. The card already outperforms my LC card at stock settings with the 17.9.1 driver. Also worth noting, I have no difference in performance between 17.9.2 and the previous driver at the current settings.
LC 64 - +50% Power Limit - Stock core - HBM 1100:
Air 64 w/LC Bios - +50% Power limit - p7 at 1702 - HBM 1100:
17.9.2:
LC 64 - +50% Power Limit - Stock core - HBM 1100:
Air 64 w/LC Bios - +50% Power limit - p7 at 1702 - HBM 1100:

Interesting that Tony. I was able to complete a Timespy bench ok at 1225Mv. The new drivers also seem to favour undervolting too as I was able to run at 1100 and 1150 on states 6 & 7 for a more stable boost clock ok where I had issues doing this on the previous 2 drivers. Overall all though, I seem to have lost a little bit of performance as I can't get over 8000 graphics score on Timespy regardless of what settings a try, where as I was getting over 8100 previously...
Well fair play to my EVGA 1000W Supernova PSU! It's coping with Crossfire Vega 64 admirably. 
I'm able to run them both 50% power limit 1090 HBM 1767 core 1250mv. No crashes so far and Timespy runs a treat! 13,588 scored, will improve for the bench thread though.

Some set up you're running there bully. Those 2 cards must look awesome in your case! Got a pic?Well fair play to my EVGA 1000W Supernova PSU! It's coping with Crossfire Vega 64 admirably.

Yep 1000W should be sufficient, nice.

Vega doing the business in project cars 2. 1440p high msaa and highest settings apart from grass. Back on the 17.9.1 driver for now though as latest driver is total rubbish for me.

Sure, if you can excuse my lack of photography skillz!
The Obutto sim racing rig, don't seem to do much sim racing nowadays though. Took me years to realise that even after years of practice, the best I will be is AVERAGE!
Thats an NZXT Phantom full tower case. I quite like it
Side off:
Had to put one rad just blowing out the CD drive bay! The other is in a kind of push pull with the side fan
Oh and, excuse the dust! Need to give it a bit of clean!
HWinfo was showing 366W for card 1 and 361W for card 2. CPU was pulling 155W, so thats getting close to 900W. Thats without all the SSD's HDD's fans etc.
Really was worried I would have to get a 1200W for crossfire, so pleasantly surprised.

That'a my only real gripe with Vega, The insane power draw, I could understand if it was faster than a 1080 Ti but it's only just about as fast as a 1080 and a 1070 in some instances, With the settings cranked in wattman and an 1800X at stock, I've seen the system easily pull over 650 watts which was a little scary considering I had it in a system with a 650 watt PSU, It actually tripped it and shut the system down, That's insane and not in a good way, Swapped the PSU out for a 1000 watt since though.
With a 1080 Ti overclocked to 2050/6000 and the same stock clocked 1800X the most I've seen is 450 watts, AMD NEED to get their power usage sorted out by Navi.
