Hi everyone!
Something happened to my rig the other day and I was hoping than someone here could help me figure it out.
I'm running one MSI R9 390x and two MSI R9 390 in an oil cooled rig and it's running very stable with Claymore's Dual miner 4.4 at approx. 90.4 Mh/s on ETH and 2125 Mh/ on DCR.
It's been running stable like that for a weeks (just different versions of the miner), always the same speed.
This is how it normally looks like:
10:59:57:620 43c ETH: 05/25/16-10:59:57 - New job (target 0x0000000225c17d04) from eth-eu.dwarfpool.com:8008
10:59:57:624 43c ETH - Total Speed: 90.439 Mh/s, Total Shares: 3477, Rejected: 0, Time: 21:41
10:59:57:628 43c ETH: GPU0 29.704 Mh/s, GPU1 29.692 Mh/s, GPU2 31.044 Mh/s
10:59:57:632 43c DCR - Total Speed: 2125.320 Mh/s, Total Shares: 4133, Rejected: 77
10:59:57:635 43c DCR: GPU0 698.034 Mh/s, GPU1 697.751 Mh/s, GPU2 729.535 Mh/s
But then something interesting happened, the next display of speed shows this:
11:00:15:757 43c ETH: 05/25/16-11:00:15 - New job (target 0x0000000225c17d04) from eth-eu.dwarfpool.com:8008
11:00:15:764 43c ETH - Total Speed: 97.979 Mh/s, Total Shares: 3477, Rejected: 0, Time: 21:41
11:00:15:770 43c ETH: GPU0 32.796 Mh/s, GPU1 32.778 Mh/s, GPU2 32.404 Mh/s
11:00:15:774 43c DCR - Total Speed: 2302.493 Mh/s, Total Shares: 4133, Rejected: 77
11:00:15:781 43c DCR: GPU0 770.712 Mh/s, GPU1 770.285 Mh/s, GPU2 761.496 Mh/s
So I have a sudden increase of speed from doing nothing. And also it's pulling no extra watts from the wall.
It kept running stable like this and I tried to restart the miner after a while to see if the speed remained the same...it did.
I restarted the entire machine, still same faster speed.
What also changed is that the miner started showing GPU temp, which it never does otherwise.
Checking the windows logs shows these two entries between the above timestamps: (sorry, it's in Swedish but you should get the idea anyway)

So it keeps running like this for a few hours but since I'm in the process of building a second rig I figured I want to clone this one to have the same speed on the next rig.
After cloning the drive it's back to "normal" speed again and I can't figure out if and how it's possible to make it go faster again...
but i try eu server eu1.ethermine.org:4444 and eu1.ethermine.org:14444
