  Windows is never needed when you have pimp - Polaris and atiflash are included. Here is the quick version: atiflash -s to save the existing rom, example: atiflash -s 0 gpu0-stock.rom to save the rom from gpu 0. RDP in and click Polaris load the file you just saved click one click strap mod save as another file atiflash -p to flash it, example: atiflash -p 0 gpu0-modified.rom to write the rom to the gpu0 from the file.. Also, we will be releasing an even easier way, PBE CONSOLE edition - in the next pimp image. Thanks!

  @dax said in DaX AMD Overclocking guide (including RX 470/480/570/580 and others): Sapphire_HynixGDDR5_RX580_8GB_Modify_Bios.rom What ROM/config for MSI RX480s? I know I can use the 580 BIOS, but not sure what values should be. . .I think ; ) I have 4X (MSI RX480): Part num: K4G80325FB VendorID: Samsung Size (MB): 8192 Density: 4M x 32 Type: GDDR5 And 1X (again, MSI RX480): Part num: H5GC4H24AJ VendorID: Hynix Size (MB): 4096 Density: 4M x 32 Type: GDDR5 Thanks for any head's up!!

  This a basic guide on how to flash your GPU with a BIOS created in PolarisBiosEditor. Please make sure you understand all the risks that comes with playing with the BIOS before you try this. I dont take any responsibility of damages. (I dont claim my way is the only way nor the best way, but this is how I do it and it might be useful to someone) You will need a computer with Windows. Download this two programs and install them: PolarisBiosEditor: https://github.com/jaschaknack/PolarisBiosEditor ATIWinFlash: https://www.techpowerup.com/download/ati-winflash/ Turn off PC and insert the GPU you want to flash into a free 16x PCI slot. Turn on PC. When in Windows start ATIWinFlash as admin (right click-run as admin). Make sure you have selected correct card in the top corner where it says "System Video Device". (Pls note that only AMD cards will be shown here and if there is no AMD card connected ATIWinFlash will not start) Click on "Save" and save the bios on your computer. Make sure you save it somewhere safe, in case you might need it in the future. Since this is the original BIOS. You can then close ATIWinFlash. Now open PolarisBiosEditor. And click "OPEN BIOS" and find the BIOS you created earlier. (Make sure you are showing all files . if you cant find it) After you have opened your BIOS click on "ONE CLICK TIMING PATCH". You should then get a windows that confirms that it have applied new straps. Save this new modded BIOS. Make sure you dont overwrite the original BIOS. Then you can close PolarisBiosEditor. Now open ATIWinFlash as admin again. Once again make sure you have selected the right GPU under "System Video Devices" Click on "Load Image" and load the modded BIOS. Click on "Program" and that should flash your modded BIOS onto your GPU. Turn off computer, take out GPU put it into minning rig. Profit.

  You can reflash AMD BIOS using atiflash. We have also provided multiple tools for inspection and modification, such as OhGodATool, atitool, and PolarisBiosEditor. Normally, I would use gputool to experiment and tune, and if I wanted to say move that GPU around to other rigs, I would use the information I learned with gputool to create a new BIOS, starting with the cards BIOS as a source, and reflash the card. Putting the lessons learned into a new BIOS, lets me make whats best for a card, into the card, so I do not need to track its cpu-config.json settings. In practice though, I must admit, I have been just jotting down what a card can do and slapping it on a sticker :)

  @Anjin, I am only setting the clock, core and power in the gputool config file. I used the same settings as I did in Ethos. I will need to put the SSD back in and do the "helpme", but the same SSD in an Nvidia only rig works fine, except I noticed that the hashrate per card using ethminer is also approx. 1MH/s per card lower than in ethos with the same overclock settings. So...clearly I must be doing something wrong.

  @sobeit Did you flash the BIOS with a modded BIOS or just use the stock BOIS for each card and then play with the frequency limits within GPUTool? Your hash rates are great and the power used is average as if not modded. Can you give us a detailed explanation of exactly what you did to accomplish your numbers? And provide a sample of your "gpu-config.json" file?

  Double check your miner profile using pimp --edit. Read the comments close, and check the FLAGS.

  In this example we are simply guessing and doing some trial and error. With a few gputool commands and simple text editing, we will: Decrease the temps from 80C to 65C. Decrease power usage by 20W per eGPU. Hashrate remains about the same, up to a 10 h/s increase overall. Note: These may not be the best guesses or settings but we have made improvements within a few moments with little effort thanks to PIMP and gputool.
