    WARNING - CORRUPTED vBIOS FLASH MAY RENDER YOUR VIDEO CARD UNUSABLE!
    PROCEED AT YOUR OWN DISCRETION.
    It is now possible to overclock the FirePro M5100 thanks to a modified vBIOS created by NBR user valuxin. He is also the creator of other vBIOS mods for the FirePro M6100 and several Quadro cards.

    If this modified vBIOS is helpful to you, I strongly urge you to donate to valuxin to show your support for his hard work.

    The modified vBIOS is based off of version 015.036.000.006.044815.

    Features:
    • Core voltage increased from 1050 mV to 1100 mV
    • TDP increased from 40 W to 55 W
    • Max core clock increased to 1200 MHz
    • Max memory clock increased to 1500 Mhz
    • TDP OverDrive limit to 50%
    If you want to share this modified vBIOS, please link back to this thread instead of reuploading the files. Thanks.

    SHA-1 stock 015.036.000.006.044815 vBIOS:
    f6c1ec4a4c8ff8e3ea45088ccd11a1376ce8049f

    SHA-1 modified v0.1 vBIOS:
    e26daaf75285f7dce6fa8b131b9764a8a507d17d

    Tools required:
    • USB flash drive for DOS recovery in case of corrupted flash, or if you prefer flashing via DOS

    Guide:
    Preliminaries:

    • Backup your original vBIOS using GPU-Z
    • Download the modified vBIOS, verify SHA-1 hash using HashCheck to ensure there no corruption of the vBIOS files (right click file → checksums).
    • Create a bootable DOS flash drive using Rufus. Copy ATIFlash and the stock + modified vBIOS files over to the flash drive.
    • Ensure that Secure Boot is disabled and Legacy ROM is enabled in the UEFI to allow DOS to boot.
    Flashing:
    • There are several options to flash the vBIOS:
      • Flash in Windows using ATIFlash GUI
      • Flash in Windows using ATIFlash via command prompt
      • Flash using DOS
    • I personally flashed in Windows using the ATIFlash GUI. Close all other running applications before flashing.
    • If your flash is corrupted, or fails, you will have to recover your video card via DOS. I cannot help you with this.
    Overclocking:
    • Overclocking tools are down to your personal preference. I used Sapphire TriXX.
    • A good place to start with overclocking is setting core clock to 875 MHz and memory clock to 1250 MHz. I believe that most, if not all, FirePro M5100 cards should be stable with this overclock.
    • Run your stability test for 10-15 minutes and look for any signs of instability (e.g. application crash, graphical artefacts, texture issues etc.)
    • If stable, increase the core clock by 10 MHz and run another set of stability tests.
    • Then increase memory clock by 25 MHz and run another set of stability tests.
    • Continue until signs of instability are found, revert back to your previous stable overclock.
    • Note - even if the overclock passes your stability tests, other applications may case the overclock to fail. For example, one of my overclocks was stable in FurMark and Valley, but caused CS:GO to crash.
    Results:
    • In the end I was able to achieve a stable core clock of 930 MHz and a memory clock of 1375 MHz (stock core clock is 775 MHz, memory clock 1125 MHz).
    • This overclock boosted the performance in the Valley benchmark (Extreme HD preset) from 538 to 597.
    • Please post your overclock results in this thread! :)

    I just flashed mine and am about to start testing. Do you recall what kind of temp increases you saw from stock to max?

    565 on stock and 668 running at 925/1400

    Temps seem fairly consistent, I'm seeing a max of 75*C (ambient room temp 20*C).

    I just installed an m5100 in my precision m4600. I am new to overclocking, so im sure i could be missing something. I didnt need to flash the vbios to overclock this card.

    seems to be running fairly stable at 985/1500, but my Valley score was only 544(extreme HD) and 513 running on stock.

    I dont have any other benchmarks really, except Heaven and PerformanceTest 8, but if you guys have results from either of those id be interested to see them...not sure why it isnt performing as well.

    Ok so that proved unstable, driver crashed playing Dishonored. Now ive got it stable at 975/1400. Played Bioshock on ultra for an hour and some Dishonored, and Ori with no problems.
    max temp was 68 which happened during Bioshock.

    I reran Valley and got a 640 which still seems a bit low but more in the ballpark. Any ideas?

    What is your gpu temp on the load after overclocking?

    Disclaimer: i realize this thread is about the m4800. However, i am continuing to post here because it seems to be the only thread about ocing firepro m5100.
    I didnt need to use the modified vbios on the m4600, overclocking is already unlocked. The maximum voltage cannot be changed but it is already set to 1.1v. I have no way of monitoring the total power consumption(that i know of). Im definitely an oc newb.

    My maximum temp so far was 68. However im facing some serious inconsistencies that i dont understand.

    The clocks are stable (at 975/1375) and multiple programs confirm them when it goes to 100 percent load.
    However, most of the time, it performs much lower than it should on these unigine benchmarks (lower 500s on valley) and seems to not get as hot as it should.
    Then sometimes it acts how it should with results to match. Im at a loss to explain the difference. Power settings are always the same and i cant find anything in background processes that explains this

    It seems like it's not just only me, who modified the vBIOS (obviously). The overclocking and performance impact are limited by TDP settings of the vBIOS and max power consumption of the card itself. For ex., you can overclock to 975/1375 and if the vBIOS is limited to 40w TDP - you'll gain almost nothing in performance on full load. If you want, you can share your vBIOS so I can say exactly what was changed and what impacts performance.

    Haha i think theres a slight misunderstanding..:D Im not even using a modified vbios, im just using msi ab to overclock. I guess i didnt have to use a modified vbios because im on an m4600 and not an m4800 (this card was not recommended for the m4600 but it happens to work). The max voltage is already set to 1.1v(probably because the driver thinks its a different card), im not sure exactly how that relates to the maximum TDP, but im definitely seeing somewhat of a performance increase just based on the voltage. I dont think I can change the voltage or TDP anymore without modifying the vbios, but in terms of voltage it seems to be the same as in your modified vbios.

    Whats confusing to me is how inconsistent the performance is on the Valley, I havent tried enough other benchmarks i guess to see if its just this one or not.

    Is any of this making sense? like I said, i dont really know what Im talking about..o_O

    It's 100% that you card using modified vBIOS. Just share it with me and I'll tell you what was changed vs original and what can be changed to increase performance.
