My second ZEC + XMR+ ETH thread builds info links thoughts and photos.

[philipma1957]

Hmm... I have some other core clock mods, which seem to preclude me from raising the core clock rate above what is already set (lower, between 1075 to 1125).  I may have to flash the original roms back onto the cards and start fresh.

More than I'm willing to start this late.  Thanks for the feedback.  460 to 470 H/s seemed low...

Yeah xmr likes higher cores.  Still gentle on power use.

Hello everyone... just got back from 2.5 weeks away and looking to optimize what my 2 rigs are running based on current profitability scenarios.  I was pretty lucky while away... rig #1 (W7 - 4x470) ran the entire time on XMR GPU 9.6, XMR CPU 3.5, & Burst mining. In fact, that rig has been doing that exact combo for very near a month now with not 1 second of down-time, which is something I thought I would never see.  Rig #2 (W10 - 6x470), actually did better than expected, running 10-11 days XMR GPU 9.7 and CPU 3.5 until crashing. Still, that's the longest I've had that up so far so I will take it.  Got some weird error though with XMR and was not able to fix it remotely, so just switched to ETH for the last few days and it was ok.  My profit is still roughly the same for both ETH & XMR, so was going to go back to splitting rigs when I got home anyway.

Something that caught me eye recently though was the recent explosion of DCR... currently at about $2.60!  This is nearly 3x what it was several months back when I was analyzing dual mining ETH + DCR. Back then it didn't make much sense but at current rates, or even anything about $1.50 or above, it does seem to be worthwhile, so today I went back to dual-mining on my 6x rig.  Sure, it sucks power like a MF'er but seems like it's going to be worth it.  my first hour penciled out to over 1 DCR/day but that has dropped off quite a bit since, even though HR is same. I will monitor for 24 hours then get a better idea, but seems good to me at current prices. 

I wanted to mention this since i didn't see anyone factoring in DCR while catching up on the last 9-10 pages of posts here. Seems to me that with XMR maybe just being slightly better than ETH only, that extra from DCR could swing it in the other direction.

At default settings in Claymore 7.4, I was getting 165 on ETH and 2470 on DCR.  Let that run for 3 hours and was totally stable, although pulling 1045w on my 1200w PSU.  This brings me to my questions...

1- is this enough headroom (150w) to run 24/7 or too risky?  I know some people say 20% headroom is preferred and this is only 12.5%.  With some tweaking, I hope to get it down to about 1000w, which leads me to my next question...

2- what is the current consensus for best 470 4GB (MSI in my case) settings for ETH?  I currently have them all running at 1150 core/1950 mem.  I know some are running at 2000 mem but on the other end, is anyone running core at lower than 1150 for ETH?

3- Regarding the ETH+DCR settings... what is the supposed optimal mix for 470/480's?  I did a bit of tweaking and found that increasing DCR intensity by +1 starting at default 30 increased about 3% HR per +1 but only offset by a very marginal .06% drop-off in ETH HR. This held true up to DCR +4 (34), resulting in a 13% gain in DCR HR while only cutting ETH by .24%.  However, this change did end up pulling about 10 more watts, which is why I stopped there since my system is now pulling 1060w and I don't want to push it any farther than that.

Other than potentially lowering the core clock speed lower than 1150, I think i have a bit more room in the Watt-tool voltage offset area since 4 of my 5 MSI 470's have stage 7 default values of 1150-1168 and I currently only have their offset values set between -14 & -16... hoping to get those 4 running solidly with closer to -20.
   

[LoneRangir]

I've been lowering the core to ~1075 MHz core on my 470s, and this usually allows me to drop Vcore down to 0.930 V or so.  I can still get 27 MH/s ETH. Depends on the card, of course.

Give that a try.

[philipma1957]

yeah give up some hash if you have to as using 1060watts 24/7/365  will be hard on your psu.

the quark has 4 cables  with double heads. most of that 1060 watts is running though the pcie cables.  some the 8 pin cpu and some the 24 pin cable

I would worry at those power draws.

[GabryRox]

thanks to both for the advice... i figured that might be a bit much for this a 1200w PSU.

I tried only changing core clock to 1100 on the 5 MSI's (not touching the orphan Nitro at this point) and got a blue-screen about 2 minutes after starting Claymore 7.4.  After reboot, decided to go with 1125/1925 and also took an additional -2 off their voltage offset each. This resulted in only about 1-2% drop-off in HR for each coin but dropped my power useage by about 75w, so sitting right around 980-985 at this point (with DCR at 34), which I feel much better about.  I will play around with it more over the weekend though just in case I can get better results. I suspect I drop the voltage offsets a bit more, especially on the 2 GPUs that have 1160 default value there.  I would love to get it down close to 900 so I can run XMR CPU again on this rig again, but I think DCR is more profitable than CPU XMR at this point, but I will do that calc tomorrow after running DCR for 24 hours.

Use GPUz to tell you your actual voltage (middle tab).  Compare the speed bins/ voltage table of Wattman WattTool to the actual on-die value reported via GPUz. They sometimes are different. Keep dropping voltage offset in Wattman WattTool until you have your desired voltage value in GPUz

Claymore XMR CPU 3.5 - https://bitcointalk.org/index.php?topic=647251.0

The bat file is actually very simple... only need to designate your pool (-o) and XMR address (-u). Here is mine for Dwarfpool, which has been the best for me:

NsCpuCNMiner64.exe -o stratum+tcp://xmr-usa.dwarfpool.com:8050 -u 46shm7maKo9Ev35kJiAoW6ZsWSxGWkNeuBrfgcN49g9JJWQe7yE513SGRiqsper1uG9T1xFDFH3inMS G7hrKW2oMHGrTDez -p x

The other possible thing to put in the bat file would be how many threads you want to use. It auto-selects otherwise, which works for 2 of my 3 machines, but the 3rd with the i7-6800k 15MB cache, I need to add the "-t 7" command in the bat file to maximize HR.  Optimal thread useage for this miner is based directly on how much cache your CPU has.  That 6800k has 15 and each mining thread requires 2MB, hence my -t 7 command to use 7 threads (of the 12) = 14MB of cache. Exceeding that 2MB rule will actually reduce speeed.  I tried to use 8 and 9 threads and both resulted in worse performance. So, your CPU's cache divided by 2 is what your -t command should be.

The other thing to note with this miner is that at least the first time, it needs to be launched in Admin mode. But, i actually just launch it that way every time.  And, the .exe file is what needs this, so, since it is launched through the bat file, you actually need to go into the file properties of the exe file and set it to launch as admin.  This should enable your miner to start in Fast Mode.  If it does not, let me know and I can help trouble shoot. Hope this helps.

Anyone here using Suprnova to mine DCR?  I got locked out of my account yesterday while trying to update payout info and cannot get anyone to respond or help me on the Suprnova support side for over 24 hours now. Their automated email that apparently walks through how to unlock account was never sent and attempts to contact their support through 3 diff methods have not been answered.  Any suggestions, including alternate DCR pools for US-based miners would be appreciated.

I believe ocminer runs suprnova.  You could try to contact him.

Hi guys,
I would like some advice,
I have a 3 GPUs rig , but the 3rd GPU get me small troubles : when I boot the rig , it works a normal 25 mh/s (Eth mining) , but it keeps decreasing every second until it reach about 8mh/s.
I changed the PCI slot but didn't help.

Any advice before I jump in the boring work like chaging drivers ?

Claymore ETH miner?

Ensure that you have min 16gb virtual memory and powered risers.

What temp is card?

How do you set clocks?

Msi afterburner when unlocked has a hidden temp max.

Maybe it is set at 60c and the card lowers hash due to temp

[Tmdz]

I see what you mean about the calc on nano, I switched over and I have on xmr over there for 3 days now.  Nano is my favorite for xmr, very stable but it does have these huge hot streaks of blocks followed by dead time.  I use whattomine to give me average estimates so I ignore the calc on nano mostly.

I noticed no one has really mentioned sgminer for windows, only for linux.  I use sgminer windows version to mine xmr.

470/480 gets 670 h/s

1100 core 1900 mem (eth straps)

53 watts reported so it comes out to ~85 watts at the wall.  I think this is the best setting you can get from low watts to a high hash.  sgminer requires a little tweaking but it rocks once its dialed in.  You could probably get wolfs miner to produced similar results but I could never get it to function on windows.

yeah I don't both with the calculator as it is based on last 6 hours.


I did 33.4 coins since Jan 24 so that is about 2.4 coins a day or 72 in a month

[vg54dett]

Citronick : yes , and its ok there.

Phil : I think you are close to the point. I do not set clocks with anyhting else than claymore itself. But I just noticed I have no control on that 3rd GPU, claymore only show the 2 others card's temp.I set -fanmin 100 to that trouble card to see if temperature (80°c+ according to GPU-z) would reduce but it doesn't change.

So I have to understand why I have no controle on that card.
Maybe driver related..

EDIT : do you know what is the most recent driver we can use  for mining ? (recent because gaming too)

I experienced the same issue with my 480 reference 480 8 gb rig in the past. After setting clocks with afterburner, the slowing down issue went away.

[vg54dett]

Weird, I still have the same issue after another fresh windows install (10 instead of7) , a different driver , and a different riser ...
The card hashrate continue decreasing , and I still can't see her temperature through Claymore.
EDIT : almost fixed it returning to stock bios. Not maximum hashrate but better than 8mh/s ! I have now 20m/s on stock bios RX470 , but still can't get temperature in claymore, nor clock controls.

[PanneKopp]

but still can't get temperature in claymore, nor clock controls.

Hi,

are you sure, you got crossfire disabled in the driver settings ?
