Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 1091. (Read 6590718 times)

You most mod the bios if you want high hash rates.. lots of good info here:
http://forum.ethereum.org/discussion/8845/rx-470-mining/p1

Hello all!  So, I just got Claymore 7.2 up and running on my first mining rig. I am dual mining ETH & DCR.  I am not quite getting the hash rate i was hoping for on ETH, so wanted to reach out for some expert advice here.  This is my setup:

- Windows 7 Pro x64
- ASRock x99 Extreme4 Mobo
- i7-6800k CPU (I know it's not needed for most mining but it was free so I used it;)
- 3 MSI RX 470 4GB GPUs  (1 on Mobo and 2 connected via powered USB risers/connectors)
- AMD driver v16.30
- ETH Pool:  ethermine.org

I was running this on Minergate the last ~2 weeks and was getting about 19.4 Mh/s per card on ETH.

Since starting to run Claymore about 2 hours ago, each GPU is getting 20.7, so just over 62 for all 3.  While I am still very new at this, I was hoping/expecting to get 23-24 per card before messing with anything like modding bios, rom, overclocking, etc.

So, my question is, what settings can I work with within Claymore to try to increase this speed?  I do understand that mining DCR simultaneously may have a  very slight impact on ETH hash-rate but I doubt it's accounting for the 3-4 gap that I am seeing. Note that I have not tweaked any settings in Claymore, aside of course from replacing the default info in the .bat file with my personal info.

Any suggestions would be welcomed... but please keep in mind that I am completely new to this type of "programming", so no level of dumbing down can be too much for me 

Send some pix on your rig nippy.

I saw an FB's Big Sur 16xGPU rig the other day and I could just imagine the beast crunching Ethash for lunch, while not doing deep learning stuff.

Does the single PCI root thingy work well on Linux on the board?

 May anyone help me and tell me how can I fix this error:

Look at this 480 review for the XFX RX480 GTR 8GB

Removable fans and replaceable fans!

Amazingly low temperatures 60C at stock and 64C overclocked to 1475mhz!

Overclocked to 1475mhz - uses 30watts less than other 480s!

And, it is using a custom PCB using the same VRMs from the Fury X series.

And, as Bill Zoid says - it his favourite 480 PCB and VRMs are ridiculous overkill

What systems support up to 32 gpus? o_0

anyone experience a problem with motherboard slot bandwidth limiting card performance? I know mining shouldnt be affected by lane bandwidth, i think ? Gigabyte g board 1150, card is a msi 470 with polaris edit bios 1375 strap in 1625, 1750, and 2000. Card is in the last x1 slot on the board. With eth intensity 8 the card shows a lower hashrate than the other 3 that have the same strap, but with ethi 16 it is on par with the other ones. The others mine fine. I changed the strap for the weak card to 1500 just to see if it will be stable, it was stable with stock and small overclock using 1375 strap though. Will change it with a 16 slot to see it will be stable. Changed the riser as well, but still didn't help. Either way wte, but if it is stable in a 16 slot with 1375 strap that would be interesting. OS is windows 10.

edit, seems that the problem card is now stable with 1500 strap, but I still think there is problem with lanes, 27 mh, sia dcri 22. 1100/1900. Other cards with 1375 strap are getting 28+ mh, 1100/1900. GPU z showing 90 watts from gpu on all.

What is the command line to run the miner to GF1070 ? Please bat file?

Guys, I'm using AMD 16.9.1 driver and my rigs are super stable.

Not planning to update but I was wondering if someone has any experience with the latest driver?

Maybe some speed improvement... 

don't know.
Have also lots of 390 Rigs with CDM 7.2 running fine. So maybe RX driver related ? Cause R9 cards useing crimson driver.

what the most stable CDM version on Linux build, for AMD cards only?

Running v7.2 on ubuntu 16.04 and i'm faceing more and more of opencl hang errors:


This doesn't seem to be card or riser related because its randomly.
Doe anyone experience the same or has an idea ?

Thanks

Are you taking part in the Zcash (ZEC) public open source mining software contest - ends 27th October?

£10,000 prize for GPU miner
£10,000 prize for CPU miner

And, £10,000 in prizes going to the runners up?

No. All my miners are public, I don't sell private miners.

@Claymore do sell your Miner so that there is no Fee?

192.168.X.X is private anyway. No need to hide that range from us. LOL.

It is not publicly accessible ip. Only internal.

LOL

someone tested the new driver? 16.10.1 ?

Ok, i see. It would be nice.

Tray is noot good place for numbers 100 and higher. Only two digits are good there. So may be set target total hashrate in EthMan and show % of target hashrate in tray.
