Msi Rx 480 - Eth mining unstable hashrate

[shadowhlohavec]

Hi, we have 2x new msi gaming rx 480 4Gb samsung memory graphic cards, hotfix amd 16.11.4 drivers, no bios mod

- first tested eth+pasc - stable for 20 minutes - 24.5 mhs on 365 mhs on pasc (1275 core - 1750 memory)

- pc restart, everything same drivers, config, overclock...

- claymore v8 dual eth+pasc   - GPU 1 started being unstable, jumping from 20 - 23 mhs
- claymore v8 eth only           - gpu 1 jumping from 22 - 24, also difference in temperatures  - http://imgur.com/a/wcGEX
- claymore v7.4 eth only         - same results as v8

-claymore xmr miner - stable hash rate on both cards

(system crashed few times before, probs blue screen)

Please give me any advice where can be the problem. I guess it's something with electricity also because of different temperatures...

Thanks
