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

[frostminer]

Nice work. With v3.0 i have 100% eth hashrate + 33% dcr hashrate per card and near 0%/2% rejects respectively.
Are there any plans to add vcash (Blake algo) mining in dual mode?

Yes I'd like vcash support too

Yea, the blake algo is superlight! 
You can actually run it with claymores dualminer .. just sacrifice some.
Im sure this could be programmed to work in better synergy.


With the BLC mergepool .. you could then mine 8 coins at the same time.

Claymore - do you think further optimizations for fiji chips are possible? Memory controller usage seems to be sitting pretty low, and I get the feeling after playing with intensities that there's more room left for optimization.

It seems a higher ethi allows for increased decred hashrate without ethash loss. I am now pushing ~30MH/s ethash and 1650MH/s decred with ethi 20 and dcri 110.  With ethi 16, dcri can't go that high without losing a chunk of ethash.  Compare that to 30MH and under 1000MH/s decred max with lower ethi.

I tried several ways to improve performance for fiji but they failed. Had to postpone these attempts because of other features. However, I don't think that it is possible to get big speedup.

@Claymore

Could you make the ethi intensity change easily adjustable like dcri? So that I could test the speed out on different ethi without closing the miner. Currently ethi 8 and ethi 16 has no difference on my rate, which I don't know why.. You have any idea about that?

Default -ethi 8 is good. Setting values between 8 and 16 almost will not change hashrate, but high values will cause more latency when miner gets new job because there is no way to cancel current GPU round.

I need a proxy for group management, so in other words I want to point a bunch of rigs using this miner to a proxy so I don't have to mess with each rig individually but I would be able to just edit/change the proxy config.
The problem with dwarfpool stratum-proxy is that it works only one way Stratum=>getwork, and I need a proxy that support Stratum<=>Stratum, any Ideas ?

Or use an utility that can connect to miners and show their status and also allows you to send them updated pools settings, this way you can apply new settings for all rigs at once.

Even with ethi 20 there are no differences as well. so what are the ethi doing then? hmm

In recent versions, max -ethi value is 16. This parameter is related to the number of hashes that GPU checks in one round. Small values allow you to reduce GPU load and reduce Windows freezes. After some value it is useless to increase this parameter because GPU is already loaded 100%.

That was also my thought, so I do some research.
Unfortunately, it looks like, there is no utility which is compatible with your miner software....

Yes, I think I will have to write it my self, the only problem is that I need to study stratum code and see it works first, a DevOps practice would be to look if the tool exist then just use it and work on improving it.

This utility will be available in a few days, I'm already working on it.

What are you saying??

Are you working on a central-control-all-my-claymore-stratum-miners-utility ??


(just have to double check before i go banananananas)

Excellent, Thank you.

Okay so what other ways could I increase the efficiency of my cards? So far I have tried after burner and amd overclock but doesn't seem to add any hashes at all. Engine/Mem/Power Limits, all of it.. Why is this happening?

Wow.......fantastic news!!!

Guys, are you undervolting your cards? And they remain stable?

I'm using 15.12 drivers as per Claymore recommendation and my rigs (6 x 270x and 5 x 9750) are mining perfectly with stock values.

However, I would like to save some power if that will have minimal or no impact on hashrate.

My 9750 have default values GPU-925 MHz and VRAM-1250 MHZ

When I lower the values to GPU-900, VRAM-1000 the miner freezes almost instantly.

Can someone please share any successful experience with undervolting?

Thanks!

Hi Claymore

Could you please check 390x coreclock issue, when i mine with genoil miner clock is same as msi afterburner setting
but with your miner it drops around 950 with slight fluctuations.

I have MSI 390X stock, afterburner shows correct clock 1040MHz, no drops. Probably your card throttles, check its temperature.

Per GPU: Mining ETH and DCR, 29.1-29.4MHs, 870-875MHs (-dcri 60), 1350-1420 watts
Per GPU: Mining ETH only, 29.5-29.6MHs, 1290-1350watts
Results: ETH only mining, I can add 1 more GPU to be just under 1600watts.

So, you lower only the voltage but not the GPU/VRAM speeds? And you keep the same hashrate?

[Claymore]

It takes a lot of time to test solo mode, I put all my cards on it, but still not enough and I have to wait for many hours, network diff is too high. Anyway, even if I cannot find a block, I will release v4.2 in a few hours because it works with eth-proxy so it must work with geth as well.

The 390-8GB is slightly OCed, stock is 1015Mhz/1500Mhz, changing memory seems not giving any reduction in total watts.
With standard ethminer.exe, I can achieve only 26++MHs and qtminer.exe 27+MHs, but with CDM 29.xxMHs.
So if my wattage comes under 1300w, with the underclock and still maintain CDM 29.xxMHs, I can now put another GPU to fully utilise the PSU with higher total hash of 177+ MHs per rig.
So underclocking has its benefits and the rig has been running for more than 2 weeks with CDM. Temp low 70s overall.
Upgrading the Catalyst to 16.3.2 has also no obvious effect, hash, temp and stability seems unchanged.
16-20GB virtual memory as per Claymore's guide applied too.

I believe some members whom have asked for the solo feature have monster hash capability, so we would like to test it out and perhaps this way we can give you faster feedback.
