Claymore’s CryptoNote AMD GPU Miner v10.2 Update Review


While a go Claymore announced a big update for its CryptoNight GPU miner, this just happen few days a go.. On September 29 he released Claymore’s CryptoNote AMD GPU Miner v10.0, there are few more features available since now miner uses the latest framework which is used for dual and zec miners. Because of too many changes in this version, bugs were found and couple of hours later Claymore released v10.1 fixing them.. and currently v10.2 still in beta.

In this article i am going to test the new features and compare the v10.2 with v9.7.

Supported cards: Pitcairn, Tahiti, Hawaii, Fiji, Tonga, Ellesmere, Baffin, Vega.

Updates list

v10.2 Beta:

– added Nicehash pool support.
– added shares validation on CPU and statistics for incorrect shares.

v10.1

– fixed some critical bugs.
– now miner uses the latest framework which is used for dual and zec miners. Therefore several new options are available.
– new assembler GPU kernels are used.
– added “-dmem” options that can improve performance in many cases. Note that twice more GPU memory is used in this mode.
– some old options were removed, some were renamed, please read Readme for detailed information and samples.
– reduced devfee, it’s 1% now if you use secure SSL/TLS connection, 1.5% for unsecure connection.
– devfee mining is executed every hour, similar to dual and zec miners.
– a lot of minor improvements.

v10.0 BETA

Problems and Fixes
  • GpuMiner dk2an0 failed -4
    1. Increase virtual memory to 30GB. if you have 6 GPUs 8GB, set virtual memory to 6*8=48GB
    2. Also make sure you have the following lines added in your .bat file
      GPU_FORCE_64BIT_PTR 1
      GPU_MAX_HEAP_SIZE 100
      GPU_USE_SYNC_OBJECTS 1
      GPU_MAX_ALLOC_PERCENT 100
      GPU_SINGLE_ALLOC_PERCENT 100
    3. another fix, try lowering -h
  • 4GB cards hashrate problem?
    1. try adding -h 928 -dmem 1 or lower -h to 890 if that fails

All problems will be fixed soon since Claymore stated “Don’t worry, v11 will be better, I just need some time 🙂

Hashrate reports for different GPUs
  • Vega users have reported lower hashrate from 1950 to 1600
  • Vega 56 -dmem 1 -h 1800
  • Vega 56 ~1400H/s, -h 1512 -dmem 1, HBM @ 950
    XMR-stak gets ~1780
    Without HBCC CM gets 1200, XMR-Stak gets 1300
  • 470 8GB 1750 strap, -mclock 2040, ~752H/s, testing stability, 9.7 was like 680-700, but unstable.
  • RX 580 8GB -dmem 1 -h 1800
  • RX 480 8gb gets 1006 h/s eth bios and -dmem 1
Claymore’s CryptoNote AMD GPU Miner v9.7 Hashrate and Power Consumption

This tests were made on a 5x Sapphire Nitro+ RX 470 4GB Mining Rig

Claymore’s CryptoNote AMD GPU Miner v10.2 Monero Mining Performance – Hashrate and Power Consumption

Tests were made with 16.9.1 and Blockchain Compute drivers

start.bat details (default settings for 4GB gpus -h 900 with -dmem 1)

GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100
NsGpuCNMiner.exe -xpool stratum+tcp://xmr-eu.dwarfpool.com:8050 -xwal WALLET.WORKER -xpsw x -tstop 85 -tt 65 -fanmin 65 -fanmax 100

The new CryptoNote miner has around 50 H/s more hashrate per GPU, blockchain compute drivers performs better than 16.9.1 giving 20 H/s extra hashrate and also lower power consumption.

Before and After
  • Hashrate: 750 H/s – 790 H/s = +40/50 H/s
  • Power Draw: 650w – 450w (500w) = -150w

Before and After
  • Hashrate: 765 H/s – 845 H/s = +80 H/s
  • Power Draw: 100w – 75w = -25w

Before to continue further, please share this 🙂 thanks!

I will work on a brand new tutorial about how to mine monero on windows with different miners and maybe i can do it for linux as well (simplemining/ethos).

Make sure you follow on facebook page or twitter account with notifications turned on because new posts will be added with each new update.

Thanks and enjoy! 🙂
