Lyra2z - Head to Head test of CoolMiner 1.3 Vs CryptoDredge 0.4.1
Hash rate numbers are vanity metrics and can be gamed. The only thing I care about is "
which miner puts more coins in my wallet?" I've done dozens of Head to Head tests in the past see:
https://bitcointalksearch.org/topic/x16r-rvn-miner-head-to-head-test-log-3385643I've decided to test CoolMiner 1.3 Vs CryptoDredge 0.4.1 to see which one mines more coins on Lyra2z.
MINERS:CoolMiner 1.3 intensity = 20
CryptoDredge 0.4.1 intensity = 6
The Setup:I use a 12 GPU 1080Ti rig on Windows 10, split into three mining instances of 4 GPU's each (for this test, only two of the instances are used). All three mining instances are balanced to get as close to the same hash rate as possible.
Each mining instance is running at the
same time on the
same machine mining on the
same pool.
Overclock settings: 100% TDP, NO overclocking
Drivers: Nvidia 398.11
Test 1 Results: Test aborted about 4 hours into the test, the rig crashed. I'm confident that it was due to CryptoDredge, the rig had close to two weeks of uptime running Coolminer.
When I went to restart CryptoDredge, I got the following error:
> Error: bad lexical cast: source type value could not be interpreted as targetGiven the increased temps, increased power draw, and stability issues; I cannot recommend CryptoDredge, even if it does provide a few percentage point gain over Coolminer.
I'll wait until CryptoDredge has the bugs worked out to give it another try
Notes on CryptoDredge:
- GPU's run about 6-8 degrees Celcius hotter than with coolminer
- The GPU count starts at 0, whereas ccminer variants start the count at 1. this obviously makes a difference when using the -d flag
- Intensity ranges from 0 to 6, 1080Ti defaults to a 6
- I initially had issues with stability. The miner would crash the rig after a minute or two of running. I had 397 drivers on the rig, which I knew caused issues for some miners. So I DDU'd the rig, installed 398 drivers, and didn't overclock... that seemed to clear up the problem.
- No API support
