No problem Driver use to crash sometimes when the PC is mining and that I use it (file explorer, chrome for surf etc... The screen blink black and windows tell me that the driver has recover) (-7% powerlimit, -96mV core) 27.5MH/s average. So If you use it to surf or doing stuff, don't mine ... that's what I do because it is laggy and not very stable for standard use when mining. But when it is only hashing and I leave it alone (when not home for week-end or at work), the rig is very stable and can be UP for several days
Your PSU is powerfull enough for the two card ? (enouth Watt available on your 12V rail for the 2 cards ?) At 0% powerlimit, the card will push 175W, so 350W for the both cards (a part of it will come from the riser or PCI-E slot, but majority from PCI-E connectors).
I had trouble with a 1600W PSU because it has 4 rails for the GPU Connectors, and 1 rails was overloaded even if the whole system used 800W on the 1600W. May it's a hint to check. My behaviour was PC shutdown and restart when try to start mining.
@th00ber What rom did you end up getting to work? I tried the -75/-75 last night with claymore 5.2 and latest AMD drivers. It would run but mine 0 hash. I went back to stock with the latest everything and it would give 2 results @ 26 Mh/s then crash the driver. I'm really starting to think the card is no good. Maybe I'm better to sell it on ebay an buy a couple 290's instead.
@stoon I don't have flashed them. They are at stock. I'm just using AfterBurner to change the core voltage and powerlimitation to control the total watt of the card. With the stock BIOS, -96mV on core -7% powerlimit The card has at ~27MH/s
@Heliox , I used DPM-100mV_VDDC-100mV_MVDDC.rom to re-flash my Nanos (most stable for my cards) but they are hashing only about ~21MH with core 800 and memory 300

Just been quite busy lately. Sorry!
900 core is not working too

When adding voltage offsets to the rom, the power has to be completely off for the controller to reprogram itself.
Further, if it doesn't work, reinstall drivers. I know it's a hassle, but it'll work ;-)
Is there somewhere that the all R9 Nano BIOS/roms are available?
All the links still work, but you will need to change the domain name as that has been sold.
just change "http://www.mininghwcomparison.com/" to
"http://62.212.74.86/~mining/"
