just out of curiosity what is the population of your mining farm and stats on different cards
For DMD Mining I have 7 R9 290s and 1 R9 280x spread between two rigs.
and free power i hope this beasts eat a lot kwh
i sold all my 6x 280s and replaced them with 9x 750ti
only my main pc have 2x 290 watercooled
but from time to time i relax there with a game and i did keep the gpu mainly for that
no in winter i still mine with the 290 nice extra heating for the room
but in summer sure only 750ti will run
I bought almost all the 290s to mine Litecoins when you could mine LTC with GPUs. I almost paid for them with LTC, Doge and VTC. At this point I have paid off my capital investment for equipment. However, as you pointed out, these devices consume power like I eat potato chips. They will also eat PSUs if you drive the cards to hard. I have been lucky because all of my GPUs have survived two years of constant mining at full power.
Dunno if realhet still active to post it his site, but there are plenty of other sharing sites Mega ....
DiamondTahiti.elf should work on all Tahiti cards except my 7950 which is harware locked and I can not change mem clock (lower=better because it does not use card mem, added heat = lower OC potential)
Pallas can confirm some cards hardware locked
Anybody can beat me 26.02MHs on 280x bounty 1 DMD
Which brings me to another point, if groestl can be done register only on GPU this is a problem, simple ASIC register only, nscrypt tried to fight this with high mem requirement but ...!
Not sure where to go with this but DMD is not ASIC resistant
