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

[johndoe2]

I stopped dual mining on my mining rig, 3 Raisers connected to 1 sata cable seems to be a hazard.

Does the voltage commands in V10 work for RX 570 and 580 cards with the blockchain drivers? (ie; -cvddc -mvddc)? In the readme it states this option is only for the 4xx series?

Could someone link me to a resource or explain to me what the -powlim settings actually does? It is a tool to lower voltage as well?

Nvidia cards truly suck for dual mining.

!060's  23.6 eth(alt eth coin) 17.6 Lbr
vs
570      29.3 eth(alt eth coin) 65. Lbr

Hell my R9 280X 23.7(no mods) Eth(alt eth coin)53.2 Lbr - tried just to test but do not mine with this card too power hungry

You are comparing an apple to an orange.  570/580 is more in line with a 1070 not a 1060.

570 is not more in line with 1070, it is priced comparatively to the 1060 so I am comparing it to the 1060.

2x Vega FE, 40-42Mh/s each.  3770k, water cooled, two HDDs, two SSDs, 3 fans.

Idle, 90w, full load mining, 511w.

Hi Navy, how the heck do you keep mem clock from dropping to 500?  my 64's are stuck there.

-cvdcc 1000 too low?

So you could get 120 MH with 4 1070s for the same power usage.

So is anyone using version 10.0? Any perf improvements on NVIDIA?
I am still using 7.5 and working just fine, so wondering if I should consider the upgrade?

I'm having some power supply issues so I've had to stop mining until my replacement PSU came in.  Which means I'm not entirely trusting some of my settings and power consumption reading.

However, with the Vega FE public beta these were my settings:

Code:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool us2.ethermine.org:4444 -ewal 0xd909bB6EbAbBE96F46B07836267B7700C48894d2.C_VEGA_FE -epsw x -cclock 1137,1137 -mclock 1050,1100 -powlim 50,50 -tt 55,55 -fanmax 97,97 -fanmin 50,50 -cvddc 950,950

When I moved to the blockchain drivers I had to bump -cvddc to 1000,1000.  I don't completely trust that anymore as looking back I was getting lots of evidence that my powersupply was struggling.  I should have figured that, it being 9 years old and having served in two gaming/mining rigs for a good portion of it's lifespan.  For the first two weeks I had the Vega FE's it wasn't possible to pull back the core clock effectively, so power consumption must have been huge but I didn't measure it.

I'll report back when I have the new PSU in place, but I think a new PSU will let me get back to having both cards at -mclock 1100,1100.

I will mention that it can take multiple restarts, and gradually working the cards up to whatever memory overclock they would support.  Example, if I changed a driver, upon starting mining mem clock would fall to 167 or 500.  So I would close the miner, restart the computer.  Then I would change my .bat to -mclock 945, 945.  Start the miner.  If it went to 945, I would close the miner and try my 1100MHz .bat.  Sometimes this would require another restart, other times it didn't.  Once I got them to happily stay at 1050,1100 they would endure restarts without issue.

I have a friend who now has 4 vega 64's and they're all over the place in terms of what they'll support for memory overclock.  I think the FE's must have got the best binning because both of mine do 1100 without breaking a sweat.  Going back to the PSU issue, the longer I ran the cards the more artifacts and occasional hard crashes that would occur.  Now that GPUZ properly supports Vega I can see that the -cvddc voltage falls off hard as soon as a real load is put onto the cards which in turn caused the memory frequency to fall off.  So I'll have to update you once the new PSU is in.

So you could get 120 MH with 4 1070s for the same power usage.

That's easy to say without considering my situation.  My computer is doubling as a gaming/mining rig.  I can only run two video cards currently, so I wanted to get the cards that have the highest hashrate per slot.  I don't care about power consumption because we have cheap electricity.  I did think hard about going 2x Titan XP, or 1070, or 1080 Ti, but I decided to take a gamble and ordered Vega FE in July when they were released.  I don't regret it.

Is there any way to get nvidia power levels reported in stats so we can monitor and graph that?  (thinking ethmonitoring.com)

[lasttimei]

any fix on windows 7 64bit , 980 ti only getting around 16mh. I read something about using older drivers but I'm duo mining with a 1080 ti.

[Rexmint]

Does Claymore order the GPUs based on bus slot? Or is there a way to do it with the -altnum command?

[Metroid]

@claymore, how can i reset the overclocking of your program? where ca i find it? regedit? I mean, I had to change its name to reset the settings.

You should consider switching to ZEC.

I managed to run my vega liquid 1300/1100@0.86v, perfectly stable both single eth or dual eth+lbc. The speed is 42.5 single (140watt) and 41.3+200 dual (230 watt). Wattage from the wall.
If I have had win10 with blockchain drivers then results would be even better.
But 17.8.2 is only drivers that work for me under win7, blockchain drivers are broken under win7

Yes i should, but i had good results with ETH/lbry, but went to windows 10 & it sucked, back to win 7 & not getting the 20-23mh i used to get not sure what i did wrong.

[Trofo]

Thanks for good work Claymore. Keep it up.

I was using your 9.7 miner for some time but now when I see version 10 is out I will give it a try.

[Ursul0]

No external utils needed. I hardcode voltages in bios and do fine-tune with claymore's miners. (New API is good on both ZEC & ETH miners)

Would you mind please share the mod bios for 470 you are using ?

It depends on the card and memory maker. What cards are you interested in?
Generally it's pretty straight forward:
1) copy tighter straps for the top memory ranges (from 1500 -> 1750 to 2000 depending on the memory)
2) set fixed voltages(not default offsets) lowering the highest  to below 950mv. (I don't look to get the every bit of juice from my setup, so my bios top core limits are around 1180MHz@ 923mv)

You can look for ready to use bioses for various cards, it would be probably easier to find if you look here: https://forum.ethereum.org

Just to share my experience with Blockchain drivers, electricity, etc.

Pre-Previous state  :

8x Sapphire RX580 Nitro+ Special Edition (blue one) - Samsung mem - flashed silent bios (1750 strip -> 2000 strip) - nothing special
17.7.1 - drivers
-cclock 1150;-mclock 2200;-cvddc 840;-mvddc 840;
power drain - ~1170W measured on wall (idle system 150W)
running ROCK stable more than two weeks
~212 MHs

Previous state :

8x Sapphire RX580 Nitro+ Special Edition (blue one) - Samsung mem - flashed silent bios (1750 strip -> 2000 strip) - nothing special
Aug23 blockchain drivers
-cclock 1150;-mclock 2200;-cvddc 875;-mvddc 875;
power drain - ~1270+/-20W measured on wall (idle system 150W)
miner sometimes restart + lot of GPU memory errors
~237MHs


Current state :

8x Sapphire RX580 Nitro+ Special Edition (blue one) - Samsung mem + Uber-mix v 3.1 straps flashed silent bios
Aug23 blockchain drivers 
-cclock 1150;-mclock 2125;-cvddc 880;-mvddc 880;
power drain - ~1380W+/-20W measured on wall (idle system 150W)
miner without restarts - minimum GPU memory errors
~ 245MHs

Still digging around to lower electricity drainage..

[kkourmousis]

idle system 150W

This is with all of your risers and cards plugged in right?

Gpus drain some power by just being plugged in. If you want an accurate measurement per card then unplug all of your GPUs and risers and then measure your idle consumption. If you have an ssd and a later generation cpu it should be around 30-40w

But if you count the price of the cards, then you should maybe count a power consumption too, it's not a big difference in power consumption price but is still there? And when you are lacking power in your farm Nvidia comes handy.

@claymore, how can i reset the overclocking of your program? where ca i find it? regedit? I mean, I had to change its name to reset the settings.

There is no simple way to restore default clocks. You can reinstall drivers, or do it via WattMan, also in most cases drivers apply default clocks after GPU driver crash.
