    I'm looking forward to the real world test. There's no way you can get 25 mh/s with the same wattage of a light bulb.

    That file doesn't seem to flash correctly.

    My old core clock/memory are still at 947/1250. The voltages are still switching in GPUz. And the voltage is over 1V not 0.938V like in your photo.


    I used Atiwinflash.

    There were no flashing errors, it completed successfully.


    However previous power consumption was 530W running at 53.6MH/s now 507W running at the same hashrate.

    I manually change the core clock/memory from 947/1250 to 900/1000 for both cards and the total power consumption right now is 455Watts running at 50MH/s.

    So efficiently improved a little by 8%.

    Since this is a Bronze PSU, it probably uses about 386Watts total so subtracting 40 watts for CPU+FANS+HD is about 175 Watts per card.

    Uses roughly the same power as my 7970/280x except runs at 25MH/s instead of 19MH/s.

    This rom is +38mV default, so double check Afterburner or whatever, it usually set voltages even it is not running. I have no idea how it can set voltage after reboot, but it does. So adjust it to +0mV.

    It may be the same with Vddci voltage and frequencies. Your previous OC settings may override default BIOS settings.

    You can also use hawaiibioseditor to adjust voltages and freq to your needs. Each ASIC has a bit different voltages.

  • adasebadaseb Member Posts: 1,043 ✭✭✭
    I copied your values from the ROM file you included into hawaiibioseditor and flashed that one. However my voltage was around 1.05V and it was changing, it wasn't constant like yours, even though all my DPM voltage values were 1000.

    No idea what I am doing wrong.

    Question for you fine gentlemen.

    I have a 290x OCed to 1170 and I'm seeing some lines on my monitor. Is that due to the OC? How far can I push the undervolt before I damage the gpu? It draws ~360w from the wall, is that too high?

    Short answer is yes. You need to share a few more details regarding your setup if you want a better answer.

    Is this a reference 290X, and have you flashed an alternative BIOS onto the card? What are the full overclock details? e.g. memory, voltage, powertune, etc.

    It's a XFX 290X DualDissipation (non-reference) 8GB card, stock bios, 15.12 drivers
    -Undervolt = - 12mV
    -PowerTune = 0%
    -Core Clock = 1170 Mhz
    -Memory Clock = 1100 Mhz
    -Fan = 100%
    -Temp = ~75-77 C

    First, you can increase the voltage (in increments of 12.5mV) if you want to keep the 1170 MHz core clock, but I'd say keep it at 1075 MHz and don't go past 1100 MHz unless you know what you are doing.

    Second, increase the memory clock to exactly 1125 MHz (although I can't confirm whether your card follows reference timings or not). Nonetheless, tune the memory clocks in increments of 125 MHz as 1100 MHz is between straps.

    Usually, your GPU will lock up (along with your computer) when you overclock/undervolt incorrectly. You'll damage the GPU if you constantly push unfavourable settings onto it and run it for long periods of time.

    Forgot to mention: the 360W consumption is irrelevant without knowing how fast the card is hashing. The GPU alone cannot pull more than 300W from the wall as it has a TDP of 290W to start with, so remember to factor in your CPU and motherboard consumptions as well. Whether 360W is high or not is relative to the electricity costs you are currently paying vs. the hashrate your card is delivering vs. the current price of Ethereum.

    core 1000
    mem 1125
    fan 90% - temps are in the 70'sC
    28+Mh/s
    1450watts @ 170Mh/s
    Edit: Eth only - @Heliox modded rom :smile:

    Anyone running this 390 BIOS onto 290 and able to get 30MH and higher? IF so, does anyone know what wattage it pulls? Can we use the same AMD driver or do we need to download a modified driver and have to go thru that entire Windows 10 signature thing via option 7? Please advise as I want to try this soon.

    Look at my previous post. I'm using win10+16.8.1 but no need of modifying drivers and signing stuff. Just flash bios and that's all.
    Wattage - don't know, I got free electricity.
    Also overclocked 290 and 290x with stock bios can already make 30-32 MHs so flashing another bios is just a question of lowering temps.

    Any one try this on a R9 295x2?

    Those Shapphire 290s are 4 GB of course.

    Edit:

    The ref cards are flashed successfully with stilt.

    The Tri-X R9 290/290x cards remains.

    Any suggestions? links?

    Uh, he "shredded" ROPs can be activated again, or gone forever?

    Those shedded rops can easily be activated again. Just flash original VBIOS :)

    Thats incredible that youre getting 32,7 MH/s on that card!
    Im running 2x Sapphire stock R9 290 with the following settings custom watercooled:
    Core voltage: 1133mV
    Power limit: +0
    Temp limit: 95C
    Core clock: 1185mhz (a bit sketchy on 1200mhz)
    Memory clock: 1625
    GPU0 temp: ~65C
    GPU1 temp: ≤70C`
    Hashrate (Genoil): 62,3MH/s

    Should i update the BIOS on these cards?
