    R9 390x is the same as an R9 290x (~25MH/S), you just got +4GB of RAM which won't be useful for 2.6 years.

    GRID 2 - 1080p, Ultra preset 8fx16x EQAA - 105 FPS in benchmark.

    Night race 1080p Ultra 8fx16xEQAA - 134 FPS

    Ultra preset 8xMSAA - around 170 FPS during night race.

    Hitman Aboslution - 1080p, Ultra 2x MSAA - Around 70 FPS

    1080p Ultra 8xMSAA - 59-60FPS

    EDIT;; Battlefield 3 Ultra Preset 1080p with 90 FOV ( normally set at 70) around 110-170fps (depending on map)

    Racedriver GRID ( 1st one) 1080p Ultra/Max settings - around 190 FPS

    Unigine Heaven - 1080p, Ultra Preset, 8x MSAA, Extreme Tessellation - 54-56 FPS

    Furmark - 1080p Preset -4303 Points - Avg 71 FPS

    3DMark 11 - P12564 Graphics score-17068 Physics score -6955 Combined score - 7102

    I just posted the results of my R9 390x XFX in the appropriate thread FYI, here is the sumup:

    Linux / Debian stable 8.1 / XFX R9 390x 8GB / Eth 0.9.34
    min/mean/max: 26.17 MH / 26.28 MH / 26.36 MH
    inner mean: 9.86 MH/s

    Speaking of benchmarks, anyone know if OC editions with extra memory do much at all for mining on a 290x? I assume it doesn't make much of a difference.

    memory isn't going to help at the moment until DAG grows in size. you'll get ~2 years of mining out of a 3GB ram card. ~ 2.6 years out of a 4GB ram card.

    Basically it means, it is better to buy older R9 290 and 290X cards, rather than newer 390/390X cards, right?

    (esp. since I can get a 30% discount on used 290/290X cards, but no discount on 390/390X cards)

    Also how did you calculate that 4 GB RAM will not be enough in 2.6 years ? I wanna understand this formula. And 8 GB will be enough for how long ?

    The DAG is growing, so it will be too big after some years. I have seen similar calulations previously. But the switch to POS should be done before 2.6 years anyway, with good margin.

    @Technologov , I think that DAG is expected to grow by 1.7x every year. So if you start with DAG at 1GB, then by the end of year 1 you are at 1.7 GB, and the end of year two you are around 3GB. I can't remember exact source of the 1.7x growth, somewhere buried in the /r/ethereum

    I have an Asus 390x OC.
    Default clock undervolted I got 28 mhs.
    with 1100 clock and 1625 memory I get around 31 mhs

    my xfx 390x is happily hashing away at 32mh/s. Undervolted -24mV, clock at 1120, memory at 1400

    hottest of all my cards though at 81-84C

    @shutfu how do you get such a high hashrate? I've overclocked my core to 1155 and kept mem at 1500 and only getting about 29.5-30 mhs average. I have the sapphire nitro edition which runs at about 73 C

    @hushabuba are you using claymore's miner in eth only mode?

    yes im only getting 32 mhs

    32mhs is what I get with my 390x using claymore's miner. I think that is pretty good

    I get those rates with overclocking and raised power limits; my question is how do you get those rates with underclocking?

    This settings was tested on my 4xSapphire_r9_390 with claymore mode=1 (mode=0 - consumes more power):
    cclock=1050, core -50mV, AUX -50mV, 30MH/s, VDDC Power In 160W
    cclock=1150, core -31mV, AUX -31mV, 32,5MH/s, 190W
    I don't post the temperature, because I still waiting for risers from china, and they just stay in common cases )
    And the question: is any way to underclock memory? Sapphire don't let me to underclock less then 1500, but GPU Z says that memory is load only at 81% at 1150Mhz core (72% at 1050Mhz) and i think that underclocking memory will help me to save GPU_power/temperature/cooler_power/VRM_efficiency/and_so_on )
    p.s. sorry if i missed_same_thread/wrong_thread. I am a newbie internet resident )
    p.p.s of course i try to overclock memory, but this have no effect, so I think I can underclock.
    p.p.p.s sorry for my "interstellar" accent

    oh, founding a right words on this forum help me to locate a very useful post about everything I need to know about my Hawaii GPUs
