So, this is now driving me absolutely insane.

I had a play around with a couple of things last night on my rig.

The 295x2 issue seems to be kinda sorted, bit weird as I just moved cards around in slots and it seemed to improve.

Only problem now is that my Vega is pathetic. lol.

See the attached pic for details.  No matter which slot the Vega goes into, the performance isn't anywhere near where it should be.

Rig setup....

Biostar TB250-BTC (non-pro)
CPU - Intel Celeron 3950 (From memory anyway, could have that model wrong)
16gb Hyper-X DDR 2400
128gb OCZ SSD
EVGA 1000watt PSU
Corsair 1200watt PSU
1x nVidia GTX 980
1x nVidia GTX 1050ti (Also Display Card)
2x AMD R9 Fury
1x AMD R295x2
1x AMD RX Vega 56 (stock Bios, secondary bios flashed to Vega 64, not tested)

No overclocking.

All GPU's Connected Via Risers.

I've tweaked the settings for the Claymore miner (Eth intensity set to 4, secondary set to 30).

I know it's not an ideal rig in terms of power/benefit, but I'm using this to experiment and learn how it all works before getting a full rig set up and it's still profitable.

As I said it's really driving me nuts, so does anyone have any ideas?

Thanks
