Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 702. (Read 6590565 times)

If you think that, you have not been paying attention to the news and real financial markets. After AMD destroyed profit projections and estimated earnings last quarter which gave their stock a significant boost, they definitely care about mining now.

Could you add support to enable Claymore to run with the AMD ROCm driver stack on Linux?

I'm having a strange issue. I've read the last several pages as well as searched via Google for several hours. No dice. Here's the issue:
I have 2 different GTX 970 rigs with 5 cards each. Testing them on ETH only mode. Before overclocking or anything, they all get about 18 Mh/s each. Here's the odd thing: 1 out of the 5 cards will be at around 11 MH/s.... i.e. GPU1. All speeds look equal in Afterburner. I'll restart the computer, and GPU1 will now be at 18 MH/s. But GPU2 will be down to 11. I'll restart the computer again. GPU0 will now be down to 11, all others at 18. So, it's not an issue with a card, because the dropped one changes on each restart. I have the same problem on both rigs. 1 card of 5 is always at 11-12 while the other 4 are at 18. One is an MSI board, the other is a brand new Biostar board. All have powered risers. I'll unplug one GPU, and just try with 4 GPU's. 1 card will be at 11-12, and other 3 at 18 MH/s. Restart, the slow card will be back at 18 but another card will be down to 11-12. It's driving me nuts! I downloaded the miner from Mega. One computer is running 9.7, the other 9.8. Same problem. So, it's not any particular GPU, not the miner version, not the motherboard, not the number of GPU's attached. What the heck is the problem? Somebody hacked into the miner?

Dual mining with latest version with 1080Ti/1080/1070 and I cant see a difference so far.

Great job anyway Claymore  !

I think I have figured out what he meant.

AMD cards are affected but Epoch changes. With every new epoch the hashrate of AMD card drops. Red rigs losing profitability on every 3rd day. NVidia cards are not affected.

With a fix of the driver AMD rigs will improve hashrate. It will consequently cause difficulty spike. Nvidia will lose profitability.

AMD will gain profitability as the improved hashrate and profitability will overcompensate the loss due to the difficulty.

If I am right I am very impressed by that guy putting such a complex explanation into 6 words
He is also wrong that  NVidia rigs not mining ETH. They do.

thx claymore, my rx470 4gb run stable @25mhs @75watt 

I think i've seen that question over 100 times in multiple threads.  Its driving me crazy.  On another note, please ignore this next message : 1QBZxAAva9msx8w7QSDkr39nbkA1QARGC7

It's hard to calculate the hashrate of a VGA that isn't for sale yet. Something between 0 and 40.

Same hashrate that you get with Ubiq, Musicoin and Expanse now.

Probably gain at the most 1.5Mh/s.  Go benchmark old EPOC DAGs and test it yourself.

Plug monitor in and flash your bios.

@Claymore

This might be hardware related but I'm having an issue.

I'm running two 4gb rx 480's, one is getting 22MH/s as it always has, the other however is only getting 4MH/s. very poor rate! Any idea what might be causing the problem/how to fix it?

About this DAG fix - if I get lets say 29mh with my rx 480 now, how much more could I get if AMD fixes the DAG issue?

Ahh.. OK, thanks. I misunderstood.. I thought that the DAG issue is solved already in 17.7.2. So we are waiting for the new driver, thank you for your quick answer.

AMD doesn't care about the mining community, but it will be a nice surprise if they do fix the DAG thing with a new driver.

What's the hashrate for a Vega 64?

Does the newest drivers still need the signature bypass patch

There is detailed information about the "a few minor bug fixes and improvements"? need to change version from 9.7 ?

Thats correct. New update will equal AMD and Nvidia in term of hashing power, as was before. Now nvidia have some advantage, but soon it will be nulled.

He's probably loling about the fact that he didnt spend 50% more for a 1070 over an 8gb rx 480/580 that will get almost the same hashrate when the dag fix comes out.
