Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

The problem is this. Windows 7, 4Gb, 30GB swap, 5 GTX 1070 Palit super cards. Nvidia drivers are the latest. MSI Afterburner is the last. For 2 years everything worked well 32MH from the card. After changing the ETH era to 315, all cards began to show 23MH. In one rig there are 2 RX 580 and 3 GTX 1070, a 580 hash rate drop was not noticed 32MH remained, and 1070 23MH. 1660Ti is also no problem 30MH. 1060 6gb hash drop from 25MH to 22MH. Something happened at Claymore with a series of 10 Nvidia. I switched to ETHMiner 0.18.0, 1070 show 31MH. What is the problem?

What version of Claymore's miner are you using? You should be on 15 and that won't be an issue. None of my 1070s are running lower than 29MH/s. Using Claymore version 15.

Naturally claymore 15.0

Today, all miners began to issue 23MH on 1070 cards on ETH. ETHminer and Phoenix miner. What to do?

Are you using the -strap parameters?

Yes. -strap 4. Claymore miner, ETHminer and Phoenixminer all give out 23MH

Raise the GPU core frequence

LOL, for ETH you need memory bandwidth and not GPU core Roll Eyes

They asked about the GPU clock, not the memory clock. Memory clock +680. Everything worked for more than two years at 32MH. on three farms, all 10 cards of 1070 began to issue 23Mh. Reinstalling Win 7 failed. on ETHminer and Phoenixminer and Gminer gives out 23MH. On farms, nothing changed during a decrease in hashrate.

They asked about GPU clock? He say you should raise it. Huh

And i say it will do nothing for Ethash if you raise the GPU clock. Thats it, learn reading

Learn to write a wise guy.

1070's have 8GB so the problem is definitely not in the lack of memory. A friend of mine has rigs with 1070's and Win 10 and he fixes the problem with gradually falling hashrate by increasing the GPU core frequency which leads to a little increase in the consumption. But his drops were not so sudden like DimoZeka's. So if increasing the GPU core frequency doesn't help try changing the OS from Win 7 to Win 10 or linux. If this doesn't help start mining other ETHash based currency that is on a lower DAG epoch.

If the problem is in the size of the TLB cache (the sudden drop suggests that this is the most possible problem) it could be solved only by new drivers from NVidia that will increase the size of the memory block and this will result in less memory page records which will fit in the TLB cache.

The other possible problem is the inefficiently working GPU cache memory when large memory blocks are addressed (I think this is when the hashrate drops gradually). If this is the problem and Claymore introduces the -gt parameter in the future versions for NVidia cards I think there is a big chance this to solve the problem with the inefficiently working GPU cache memory when it addresses a large memory range allocated for the constantly growing DAG.
