I’m guessing that everyone probably noticed the huge hashrate drop on Bitcoin Gold network. Now it’s about 1.4 Msol/s (= 900 \* 6 GTX1060 rig), and I thought “That seems way too low”. So I ran EWBF 0.3.4 on pool.gold with my 2 GTX1070, but just a bunch of rejected shares came out. Maybe that’s the reason behind the tremendous hashrate drop. Did anyone else try mining BTG after the hard fork? ---

I see that I have to use a new EWBF miner for 144-5 Algo. > **[EWBF's Cuda Equihash Miner 0.6](https://bitcointalk.org/index.php?topic=4466962.0)** > > EWBF's Cuda Equihash Miner 0.6 144\_5 uses ~2.0GB vram 1050ti ~15 S/s 1060 ~23 S/s 1070 ~34 S/s 1080 ~38 S/s 1080ti ~56 S/s EWBF Zcash miner: Expected speeds 500 sols/s gtx 1080, 444 sols/s gtx1070. 300 gtx1060 6G. So 144-5 hashrate is about 7.5% of 200-9’s. Let’s say that the pre-hardfork BTG hashrate us 25 Msol/s ([https://www.coinwarz.com/network-hashrate-charts/bitcoingold-network-hashrate-chart](https://www.coinwarz.com/network-hashrate-charts/bitcoingold-network-hashrate-chart)). In that case, the post-hardfork hashrate should be 1.875 Msol. Where did 0.375 Msol go? Maybe some miners didn’t get the memo to change their mining program, or it was ASIC, or Malware, or EWBF got the mining speed wrong, etc. I guess we will have to wait until the mining network get stabilized. ---

Jeps, you need the ewbf 0.2 miner and your sols will be lower then you used to have 😉 The block which triggered the new algorithm ( simple said ) had a date that shifted, so I think some rigs still run on the old software. This still is a nice case to follow, even if you don’t mine it. What will the price do ? How quick will the hashrate go up ? ---

You mean the 144.5 miner ? Ewbf is there with version 0.2 Will look for the links, someone already posted them, the other Nvidia miner by Fukushima ( don’t like that one, but that’s me ) And there is an Amd one, let me search the links ---

The correct ones for BTG mining. Yes, I know I need EWBF v0.2, but i can’t download it b/c of the goddam virus alerts. Any help is appreciated! ---

can I run 0.3.4b with the changes to the bat file as they indicate? 144\_5? And windows wont let me extract it. Thanks anyhow! I will mess with it on a Win7 pc. ---

It’s an anoying problem with the latest update , Bminer and all other miners have this problem. Download, get the map to your desktop, look of the miner.exe still excists and then disable Win defender for that map. So yes, you understand the danger, but don’t want defender to intervene. ---

I don’t think that with 0.3.4. b will work, but didn’t test it yet. Going to play with ewbf 0.3. my rigs are to big I guess, so maybe have to break them down to 6 GPU instead of the 12 now. I never thought I would say this. But I hope Bminer has the 144.5 quick, for me on Zcash it was the most stable miner in the end with my oc. ( I pay 0.24 $ kwh ) but have them all on max power. Jajajja I am a hodler hahaha profit will come. May take some years, but still a believer 😉 ---

I’m trying to figure out how to calculate expected hashrates now. What are the 1060’s getting now? ---

Ewbf says the next numbers Expected performance: 96\_5 uses ~1.6GB vram 1050ti ~7.5 KS/s 1060 ~13.0 KS/s 1070 ~19.5 KS/s 1080 ~23.5 KS/s 1080ti ~33.5 KS/s 144\_5 uses ~2.0GB vram 1050ti ~15 S/s 1060 ~23 S/s 1070 ~34 S/s 1080 ~38 S/s 1080ti ~56 S/s 192\_7 uses ~2.5GB vram 1050ti ~8 S/s 1060 ~13 S/s 1070 ~19 S/s 1080 ~22 S/s 1080ti ~30 S/s I guess without oc. Will try tommorow, have to work and things here are still stable on Zcash. So let it run for the night to come. Put my mixrig back on ZCash since the new algo for BTG, ewbf wasn’t stable on my rig and no time ATM to test the new 0.3 😌 ---

> [@local\_miner](#): > > So 144-5 hashrate is about 7.5% of 200-9’s. Yep, this matches my rough recollection of my own implementations before launch. The reason we switched Zcash from 144,5 to 200,9 before launch was precisely because my implementation was too slow (seconds per solution), and there weren’t going to be sufficient solutions found per block interval to ensure security (it would become a race to finish a single PoW run, rather than a Poisson process). Looks like 144,5 on a GPU is now about as fast as my 200,9 implementation was on a CPU, so it _should_ have a sufficient security margin.
