After payment you will be able to download your bios
Make sure you are buying the exact same bios. Look at “Additional information” and compare it with your bios information. The fastest way how to do that is download SRB Polaris. In the gallery there is screenshot from SRB Polaris 3.2 of the bios. If you can’t find the exact same bios contact me via e-mail firstname.lastname@example.org and send your bios, I will add it.
You can mod your bios for free with my guide on Bitcointalk https://bitcointalk.org/index.php?topic=1954245.0
Hashrate a lot depends on memory quality, Google “Silicon lottery”, so I can’t guaranteed results. Better than stock and mem shifting for sure! I’m not responsible for brick cards and broken hearts.

Bios Mod FAQ
- Download latest ATIWinflash and run it as Administrator.
- Pick your card and save the bios with (*.rom).
- Download latest SRBPolaris and open the saved bios.
- Compare "Type", "Memory types" and "Memory size" if they are same as on product page SRBPolaris screenshot (or additional tab). Last letters like R of G don't matters.
- Simply add products you want to buy in your cart
- Go to checkout and create your account
- Pick cryptocurrency you want to pay with
- If you want to pay with another cryptocurrency select BTC and in next step use Shapeshift button

- Click program. Your PC will freeze for few seconds so patiently wait!
- It's recommended to wipe drivers with DDU (with reboot), you may do it even twice
- After reboot install latest Adrenaline drivers
- You will probably need apply ATI Pixel Patch, rename the file to "atikmdag-patcher-bios.exe" first to only patch signature.
- Switch cards to compute workload
- Make sure you don't have any OC enable, run all cards witch stock values and start miner to see if it's working good
- After that you can start to tweak core and memory clocks also voltages
- Download HWinfo and check for memory errors!
- Start with stock clocks
- Then you can raise memory clocks by approx. 10Mhz steps, every few seconds
- Use MSI Afterburner or Overdriventool.
- Once you have some errors lower clocks a bit until there are no new errors. These clocks should be stable
- After you find the best memory clocks you can set core clocks (overclock or underclock) then you can try lowering voltages.http://www.pcworld.com/article/250644/how_to_overclock_your_graphics_card.htmlHWinfo - find your GPU and the GPU memory errors line. Watch it for numbers. If there are any after few minutes your memory clock is too high. If you have few errors after hours it's no problem. But key is to have 0 errors. Memory errors can cause bad shares and may end up with BSOD
Some recommended clocks and voltages for RX cards - each card is different this is only for approx values!ETH

All of these bios have undervolted core and memory (VDDCI), but only a bit for stability with all cards, most of them also have memory OC. All bios use performance timings or Pro performance timings. You can find most of the performance timings in my Bitcointalk guide, those Pro performance timings have higher hashrate and they are not listed in my guide. You can get them only if you have my Premium pack, Pro peformance timings bios or in PBE 2.0.
Use my guide how to mod and flash your bios.
