Windows 8.1 XFX R9-390 (8GB RAM) stock 28MH/s @ 210Watts.
WASTE of $$$ IMO.
how do you figure ? at 280x clocks at only 23 mhs and sells for around 230 is vs $320 for a 390, plus the 390s will hold better resale value with their 8GB ram.
Windows 8.1 PRO/ Gigabyte Radeon R9 390x 8GB min / mean / max: 25.6 / 26.2 / 28.0
Inner mean: 27.2553 MH
Gigabytes are the worst 390s best 390s seem to be MSI and the Trixx ones which push around 30mh/s for the regular 390s and 32 or so for the x. The X is definatly not worth it for the 390s.
Win 764bit 7990 (Malta with HynixAFR memory ) - 1000MHz - GPU & 1500Mhz Memory ~ 350W/h undervolted at 1.060V
Benchmark - looks decent while actual hashing is 15-20% lower Any advice?
the benchmark by default uses the initial block & DAG size, current DAG is +30% larger and thus lower hashrates across the board.
Genoil released a new build of ethminer (1.03) that allows specifying block number for benchmarking, can find it in the CUDA thread (I'm using it on AMD just fine)
I run most of my 7970/280x at 1050/1500, altho I haven't worked with a 7990 so may not be advisable from a heat/power usage stanpoint
Can you show us the ethminer benchmark results with these settings?
Redone the tests with no change ... so any advice would help? Real mining 15-20% down compared to test. really annoying knowing this is one of the best GPUs you can actually mine on.

Soloming with ethminer 0.9.41. Unless ethminer.exe is mining on a pool?
Actual Mining: ethminer.exe -G --cl-local-work 256 --cl-global-work 8192
These are the best settings for my card. Otherwise it's a lot worse. Thanks
Just for S&G I tried those settings on one of my rigs (3x R7-370's+1 R9-290). I got 3% increase in hash rate just from that. Averaging 80MH for the rig now @ 730 watts GPU only use. (PC is a 6core AMD FX using 130watts)
Is there a way to check for error or reject rates like on other miners?
Hi. Thanks for tip. Is it that the initial benchmark is skewed because the block size is bigger now? It looks like 3GB cards get a major hit in the arm
Genoil's latest win 64 I realease produced these results:
@happytreefriends -glad it improved your hashrate and you should see over long term if it actually did. What to note is this: my settings are particular to my card and it is a computed thing not random numbers made up. You should look for stilt posts on litecoin forums so you can understand how is that computed. It's not easy but as you can see it makes a difference. Sometimes a huge one if you understand what are the particularities of your cards.
@taz002dev yeah you got it, the initial dag is much smaller than what it is now.
are you running stilt's bios on your cards? I still have it on most of mine although I use the regular bios because it's a p.i.t.a. to keep them stable.

What cards do you have , what mem, what hashes? Still thinking that my 7990 is [email protected] 42-44Mh/s. Mine has stock ROM . For this specific core and memory (Malta with Hynix AFR) Stilt has not released a bios because they are stock optimized with no to minor gains in optimizing further. Anyway I've tried flashing some others but like you said PITA :-) for stability reasons. For this one just undervolted @1055V and what you see above is what I am getting. I think it's puling 350w or so but will know soon once I built a decent platform because now it's just sitting in my desktop.
I have some 290s and I hope will get some decent bioses for those when I've got the time, stilt ones or whatever I can find to keep them stable, realatively low temps and TDP
A friend of mine tried today to mine with 7850 2gb ram But ethminer keeps telling him that no device with sufficient memory is available Any idea what to check?! Tried with latest WHQL drivers
Change VDDC to 1.020 Volts and 970/1450 clock speeds.
Measured with a seperate PSU both 2 PCIe connectors with the Powered Riser +12V molex and it only used like 160Watts, in reality probably like 140-150Watts not counting PSU efficency.
I can't seem to pass 22MH/s on my R9280x toxic win7 4gb ram. Others are reporting 25Mh a sec. that's almost 12 dollars a month difference. Also what voltage is the optimal for this card? This thing is power hungry.
