    Anyone got an idea why I am not able to have 5 480's Nitro+ running at 29.6 with the same settings?

    I tested each card one by one, and I get 29.6, connected 2-4, and I get the same results, but when there are 5 running, i get only one at 29.6 and the other vary from 24 to 27.

    Running on EVGA G2 1300

    Can this bios mode be used for RX 480 8GB – (11260-07-20G)

    Still having issue with watchdog freeing up the miner, but would like to try some mods in near future.

    Cards are Sapphire and AsRock BTC Motherboards.

    It is said in every post/YT video. The silent bios position is the one closer to the HDMI ports

    Need some advise.

    New card has bios version 015.050.000.000.000000

    The board is 113-2E3470U.S5X
    details shown from gpuz

    info from ati flash
    adapter bn dn fn dID asic flash romsize test bios p/n
    ======= == == == ==== =============== ============== ======= ==== ==============
    0 01 00 00 67DF Polaris10 GD25Q41B 80000 pass 113-2E3470U.S5X

    memory type Samsung

    Is this safe to flash to modded bios as heard and seen theirs various versions of the 480 sapphire nitro and people have ad problems with. Have card in silent mode and have backed up bios.

    Ok i managed to get flashed and tried v4 rom on here now slient mode will not boot. How do I fix silent mode to reflash with working rom ie orignal rom. Do I just boot in normal bios position then flick switch to silent mode flash rom?

    Exactly. Switch after loading windows to silent position and apply the original rom.

    Ok so managed to get running the problem is now this rom v4 or even others are very unstable on this 480 bought ETH or ETC crashes monero works perfectly fine. I have this bios or one like it on other 480s and acheaving 29MH flawless. Is their anyway if I upload bios on here someone can make changes needed for my 480 as I think its another revision of the bios yet again.

    The gpu has this on it 113-2E3470U.S5X yet the modded bios on her does not want to work

    and my other 480s have 113-2E3472U.053

    For both bioses described, the V4 Rom should work, but in some cases (bad luck) is not working. I have 12 of 480 Nitro, 9 ver. 11260-07-20G and 3 ver. 11260-01-20G and all of them works flawless. But I had one that didn't work and was not stable so I returned...

    For all the ones with 113-2E3472U.053 work flawless the one ending s5x works fine for monero but eth or etc I have to clock down to about 2000 range on ram. Could it just be bad or needs more work doing to the rom to work better with it?

    Also one question with regards monitor display how do I fix this from resulting in 800x600 when no monitor plugged in ? when using remote access to monitor?
  • midoprincemidoprince Member Posts: 198 ✭✭✭

    @Jukebox you are a genius! This bios is rock! 184-188 Mh/s ETH (850-870W wall, 1225/2240, -75mv) or 179-180 Mhs Eth + 2600 SIA(1040-1060W).If you will came in Romania i will take you to the best restaurant in town!:)

    bro
    what is your card default core clock ?
    can u give me the SN or product ID ?
    i got newest one 1342 MH default core clock but never got speed over 29.8 MH
    and the memory stuck on 2215 if increased by a bit the rig freeze

    You can't fix this with Rx series... only with a dummy emulator:

    As I said before, to squeeze more MH - it needs an individual tuning for each card. Some cards are lucky, some - not. Some people have problems even with comparatively safe clock settings in my published ROM.

    Each card need long testing to find stable strap and clock settings and all you can reach is 1.5 MH additionally. It's not worth it, as for me.

    Here is my another ROM with 1150/2150 clock settings, that does 29.8 MH. It used on my most unlucky card, so there is a big chance (but no any warranty) that almost any card can run stable with it. Use it on your own risk.

    If you VERY lucky, you can try to clock up to 1225/2300 MHz and reach 31.5-32 Mh with this ROM, but test it yourself.

    hi Jukebox,

    do we still need to undervolt if V4 ROM is used?

    Hello i used this File for bios overclock but have some problem :smile:

    from my case, 21.19.164.1 (Crimson 16.11.4) driver works without issue.. all (3GPU) can be detected. I am using V4 bios. Updating the driver to newer ones makes the GPU not detectable.. windows give error 43.

    Been testing since yesterday for stability test. with -100mV overall. i have 2 x 11260-07-20G & 1x 11260-01-20G
    1. 1150/2150 - unstable.
    2. 1125/2100 - with 1x 11260-07 + 1x 11260-01= been running for 6hrs straight without issues.
    3. 1125/2100 - with 2x 11260-07 + 1x 11260-01 = currently running**.

    ** will report further updates. Getting about 29.2Mh/s per GPU so far although individual GPU test can push some up to 30Mh/s (short test run only, long run not tried).

    No fucking WAY anyone will stably clock to 2300 mem using THIS rom.

    I have added another GPU, so I am running 3x 11260-07-20G + 1 x 11260-01-20G.
    with 1125/2115, I am getting about average of 29.3 MH per GPU. All is good within 24hrs.. till then, I will stick to this settings for ETH only mining.

    I also tried 1125/2115 with ETH + DCR, it did works but tested only for 5hrs before I switced back to ETH only.

    @ xhanzii,

    had same issue.

    Downloaded AMD/ATI ATIFlash 2.74

    https://techpowerup.com/download/ati-atiflash/

    I was able to see cards again.

    Be sure to have BIOS switch in silent mode position. Closed to HDMI ports.

    i really don't understand what means V4 bios ? and how can it be installed any guide ?

    i have 2 RX 480 8GB i overclocked it by atiflash and than when windows appeared there was problem with driver i reinstall but no solution. than i turn it to factory bios by atiflash one is okey and second one isn't showing nothing when i run windows ( i Disable windows grapic check or what is called but there is nothing)

    1.How install v4 bios and what is it?
    2.After overlocking Driver problem ( does it need wattman configuration to work?)

    can someone explain step by step configuration because there is lot of question same mining if someone write normal language how to overclock step by step it will be great work

    do you have the ROM ready modified ?

    Hi,
    I am new to this forum and mining. I have 3x RX 480 Nitro+ OC 8GB (no bios mod) and with Claymore result ~27,5 Mh each.
    Can someone help me to choose bios mod and where can I find step by step tutorial for my card, please? I have Samsung memory. 75W without load, and 550W with Claymore and 1130/2225 gpu/memory.
    thanks,

    Hi all,
    Did anyone use v4 rom for dual mining eth+pasc ?
    I tried but for me was unstable and got a lot of crashes until I quit trying..

    Don't use v4, .Easy and best way to set up follow this link forum.ethereum.org/discussion/comment/55303
    Very simple.My rig is running 186.4 MHz ( 6 x Sapphire RX 480 Nitro 8 GB )

    I tried everything, even briked one of my cards, but then I made to get it back working on stock bios. I also tried to manually mod the bios itself with polaris but no luck.
    My cards are http://www.ebay.com/itm/302224166896?_trksid=p2057872.m2749.l2649&amp;ssPageName=STRK:MEBIDX:IT
    and I was looking for 29+MH/s Micron memory
    any help would be great,
    Thanks
