  • AMD + Nvidia Mining Rig

    Previous miner here getting back in to it. I bought some more GPUs and was originally going to use all Nvidia and mine ZEC, BTG, and MONA. But now ETH has become more profitable than it was and I ordered some AMD GPUs also.

    So, now I need some help deciding how to set up my rig(s). It will be 7 GPUs for now.

    My equipment:

    1x GA-Z270XP-SLI (6xPCIe) in Rosewill rack-mount server case.
    SeaSonic 1200W PRIME Gold

    1x Z270M MORTAR (4xPCIe) in ATX Mid case.
    EVGA 850W B2

    2x RX 570 4GB
    2x GTX 1070 Ti Mini
    2x GTX 1080 Ti SC2
    1x GTX 1070 SC

    The only thing is the 1080 Ti isn't very good at mining ETH. I could make $2-$4 more per day mining Bitcoin Gold or MONA with the 1080 Ti's than I could mining ETH.

    So, my question is can I run the other GPUs in the same rig mining ETH? I've done it in the past but I know things change. If I want to run custom BIOS on the AMD GPUs do I still need to use Pixel Clock Patcher? Can I use the latest AMD drivers?

    Thanks

    I'll be hoping someone will share their original BIOS from RX 570/580 4GB/8GB with the rest of us.

  • Re: Timing straps?

    *Short answer is you would lower the effective speed of your card if you copied the 2000MHz timings everywhere.

    The 2000MHz uses a higher timing. You will need to first understand memory timings, which are separate from memory speeds. Higher timings mean more time in between memory accesses. Lower timings mean less time between memory accesses. The less time, the quicker the access.

    The reason the lower speed (1500MHz) has lower (faster) timings is because lower timings may cause instability with the higher speeds. So to alleviate any instability in the GPU, card manufacturers lower the memory timings of the higher clock rates.

    You may notice with the stock BIOS that if you overclock your memory to 2000MHz (or at a certain point around there), your hashrate doesn't get any faster because the timings got higher, which lowered the effective speed (hashrate) from what it would have been had it kept the same timings of the stock speed. So to go around that, we mod the BIOS, so that at 2000MHz the memory will use the lower (faster) timings that go with the 1500MHz speed, effectively increasing our effective speed. Keep in mind this will void your warranty and may cause some instability and/or memory errors because you are pushing the memory beyond what the manufacturer's have tested as stable and safe for all operating conditions. Not all cards will be stable at 2000MHz with 1500MHz timings.

  • Sapphire Nitro+ RX 570 8GB Ether Hashrate

    So I got my Sapphire Nitro+ RX 570 8GB (Micron) in yesterday and after watching this video (http://curvetube.com/BIOS_Mod_Sapphire_Pulse_RX570_8G_MICRON_for_Ethereum_AMD_Radeon_GPU_Mining/HYh3H3-OOHA.video) I was able to change the straps to 1750. I know he's using the PULSE, but from what I can tell the PULSE is the same card but with only a single 8-pin and lower core clock. He's getting higher hashrate from the simple changing of the straps. He's getting 29MH/s while I'm only getting 27MH/s even at the same memory clock of 2175MHz, I can't get to 28MH/s.

    That's funny because all my other RX4xx/5xx cards are 4GB and none can go over 2000MHz without memory errors yet they can all do 27MH/s with 1750 straps. I also tried using Anorak's Samsung Micron memshift 1500 but crashed the system when I OC'd to 2000MHz memory, never seeing 27MH/s. https://anorak.tech/t/sapphire-rx-570-nitro/5332

    I'd like to think at 2175MHz this card could get 29MH/s. Any help would be appreciated.

  • Re: Ethereum Mining pool for noobs! noobpool.com

    Okay I've got Calymore up and running with my 6 GPU mining rig. It actually went up 5MH/s after switching to noobpool.com(160MH/s) instead of nanopool.com(155MH/s). I found 10 shares in the first minute! :)

    I've also got my PC mining with 1 GPU too, but I take it offline sometimes when I want to play a game.

    I notice at noobpool.com it shows an increase in the number of miners, but the pool hashrate doesn't reflect accurately. I wonder why? Maybe it takes time to reflect as it's only been 5 minutes since I got it started. *The pool hashrate is going up now.

    *Also, is there a miner that doesn't take out for dev fee? Claymore has a 1% dev fee no matter which pool I'm using.
