Hi Guys, Hope someone can help me take my rig to the next level in terms of hash rate. I’m running 2x XFX RX 480s 8GB 256 bit on the claymore miner: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux) and getting a very stable 40H/s per card. I’ve been reading up trying to find the best stable bios to run to get more H/s with less power (if thats even possible) and have seen people hitting 50H/s on claymore with a custom bios. But I can’t seem to piece together which rom and what settings to target. I downloaded atiflash 2.7.4 and am ready to go, but most searches point to dead packages for roms like Heliox. Apologies if this has been covered before, but I’ve been trolling through hundreds of pages and can’t seem to find a consolidated set of steps and guidance on the best way to go.
Any suggestions are welcome. Will end up with 4 RX 480s on Windows 7 once I get 2 more cards setup, I’m also configured for simplemining.net but haven’t tried it yet.
as you did for ethreum, however on some of the 480s you need to up the voltage to like 1050 mv to get the system stable.
Massive your millage may vary there. But to get to 50 on all my 480s all I had to do was replace the mem with the line above and then push the memory voltage up to 1050 for stability, at 975 I found it crashed.
Was also able to push the memory up to 2200 on the 8gb models and only 2k on the 4gbs.
Ok, here is the custom BIOS I use for my non-reference XFX RX 480 8GB. The hilarious thing is that it uses the exact same settings that @Bagdar13 reccomends, when I started work on this hours ago! ATIWinflash will complain about the size of the BIOS when you flash it, but it will work just fine. Hopefully this helps, @yarink!
Hold on a second, @cryptomined! What in the world do you mean by “a thief’s software?” I mean really, Claymore is not a thief. He doesn’t have his miner secretly taking away from poeple’s mining time. Even if he was doing this, how would that make anyone using it a thief? Your argument isn’t even logical. Besides, everyone using his software is aware of the fee he puts on mining. He clearly stated that it charges a fee.
Really, I was only using his Zcash miner as an example of the custom BIOS’ mining speed. I wasn’t even aware of Genoil’s Zcash miner when I posted my BIOS. If you have access to faster mining software, then please use it! I never said anyone was required to use Claymore’s miner. We have the freedom to choose, after all.
I just used the polaris bios editor and re-flashed the bios with those 2-3 edits. Nice thing about the red-devils is they are dual bios as well so incase you really mess up you have the 2nd.
To be clear you can change it in the polaris bios editor. or in Wattman you can just click manual and type 1050 where it says 975 under the memory setting. Both will work after changing the memory timing.
What’s up Wolf, it appears you and Heliox are correct and I was wrong. People do not want to do the leg work to understand what they are doing. Please accept my apology
I was expecting silentarmy w/ nerdralph to push 48 Sol/S and use less power but that wasn’t the case. Should I try anything else? What can be tweaked? I believe the default is 2 instance per GPU. Does 3 make a difference?
It seems that claymore yields 2.1 better results in windows on stock Rx 480s. In terms of code theft and all that, if that is the case I would obviously lean towards the original source. My card firmware/details are above.
