Hello everyone... with the recent release of Claymore's dual ETH miner v8.0 that now supports Pascal mining, I've been tweaking settings for the past day or so trying to find the best balance for my system.  I thought this would be a good opportunity for people to share their results and settings, as Pascal mining seems to differ vs the other dual options like DCR.

I'm running ETH + PASC on 1 of my 2 mining rigs. Specs are Windows 7 Pro, 4 MSI 470 4GB GPUs (1 onboard and 3 via USB risers - all 4 are strap1500-modded and under-volted),  1000w Rosewill Quark Plat PSU.

My best solo ETH mining settings:  GPUs set to 1125/1975;  Claymore .bat settings at default.  Getting about 110 Mh/s using about 610 watts.

Initial ETH + PASC settings:  GPUs set to 1125/1975 (same as ETH solo);  Claymore .bat settings: ETH intensity at default 8, PASC intensity at 20.  This attempt resulted in a blue-screen & reboot about 1 minute after launching miner.

Attempt #2 ETH + PASC settings:  no change to GPUs 1125/1975;  Claymore settings: ETH at 6, PASC at just 10.  This ran stably for 1-2 hours, getting 111.2 on ETH and 555 Mh/s on PASC... using 670w total system, so about 60w added for PASC @ 10.  % of rejected PASC shares seemed high though at around 9-10%.

#2a- Bumped up PASC intensity to 11, which added about 55 Mh/s but did not really hurt ETH. Added about 5-6 watts.

#2b- Bumped up PASC intensity to 12, which added about another 55 Mh/s and barely lowered ETH h/r. Added about another 5-6 watts and ran stable for about 10-15 minutes but then crashed.

Attempt #3 (currently running stable for close to an hour as of this writing): lowered clock speeds a bit to 1125/1950; ran Claymore again at the 6/10 settings. Getting slightly less h/r of course due to lowered clocks but still getting 110 on ETH and 550 on PASC.

#3a- Bumped PASC up to 11, resulting in expected add of about 50 h/r and 5 watts.  This seems to be running overall more smoothly than attempt 2. Rejected PASC share % is down from 9-10% to about 3-4%.

And, just before I hit post, i get a run of like 8 rejected shares and got temporarily disconnected from pool because of it. although now seems to be running ok again. I will continue trying to add 1 incremental intensity to PASC until things start to get unstable.

Would be very curious to see what others have done with this dual option.

Sapphire Nitro+ RX480 OC 4GB.
Core clock 1190.
Mem clock 2120.
Voltage offset -15.
Claymore v8.0 default settings.
ETH 26.5, PASC 395.

I found a bug in CLaymore v8 If you disable one of your GPU then enable it again, the GPU is only enabled in ETH but still disabled in PASC.

You need to hit that gpu number again to enable dual mining.

Got my rig up to 14 on Pascal and ran for maybe 30 minutes then crashed.

Re-did my bat file to start at 13 and backed clocks off to 1940 and relaunched Claymore. It has now been running like that for over 2 hours stable: 

109.5 ETH,  711 PASC, but about 8-9% rejected shares.  Anyone getting this kind of high rejects?  They seem to come in spurts... none for 20-30 minutes then 8-10 within less than a minute.  Even caused temporary disconnect from suprnova pool a few times.  I know with other coins excessive rejects usually means too much overclock but not sure if thats the case here or not. Maybe tomorrow I will bump it down to around 1900 but much lower than that it won't be worth it due to loss of ETH hash-rate.

Yeah I tried also, ran for like 30 minutes and just froze the entire system and needed to be yanked out of the wall outlet to reboot.

Went back to SIA

Well, my rig seems very stable with 13 Intensity for Pascal. It ran overnight and now pushing 12 hours that way. Overall rejects trending down and now at 6.8%.  I will start pushing it upwards today with the current 1940 clock settings and see what happens.

Okay been playing with the settings

found out a few things

the panda miner has the 8 rx 480 4gb gpus that are flashed to 1145 and 2050

It does not like claymore 8.0 at full -ethi 8

It runs really well at -ethi 6 and no pasc

it runs well at -ethi 4 and drci 4

so  I think I need to run a separate panda miner on a different email address with simple mining

update   I now have the panda miner on -ethi 4  -dcri 4
-
epool stratum+tcp://us1.ethpool.org:3333 -ewal 0x3ef297e47404a771139472b93621f82c8a832857.Simple -esm 0 -epsw x -allpools 1 -mport -3333 -ethi 4 -dpool stratum+tcp://pasc-eu1.nanopool.org:15555 -dwal 86646-64.d3c2c1e866a79ef4.simple -dpsw x -dcoin pasc -allpools 1 -mport 3333 -dcri 4


and I have 5 2 card rigs  on -ethi 4 and - dcri 15


-epool stratum+tcp://us1.ethpool.org:3333 -ewal 0x3ef297e47404a771139472b93621f82c8a832857.Simple2 -esm 0 -epsw x -allpools 1 -mport -3333 -ethi 4 -dpool stratum+tcp://pasc-eu1.nanopool.org:15555 -dwal 86646-64.d3c2c1e866a79ef4.simple2 -dpsw x -dcoin pasc -allpools 1 -mport 3333 -dcri 15

For now I have smOS with 2 emails 1 is all msi rx 470/480 rigs one is the panda miner.
Need two browsers  but it works on the same pc at the same time

the cpus in the msi rx rigs are all i5's  I suspect I can go higher
the cpu in the panda miner is a lowed mobile welded in so dual miner may not be practical at all




looks like my 2 card rigs with tons of overhead are really good dual mining

I can do -dcri at 22 !

No  I just bumped from 22 to 24!

It is doable because of psu overhead
a four card rig has 2 cards not 4
and all cpus are i3 or i5

I just started modding the BIOS and playing with clock speeds in the past 24 hours, but here are my results - please do advise if you see something wrong.

Currently in a test rig:

GPU 0: Sapphire RX 470 OC 4GB REF = 29.1 + 145
GPU 1: Sapphire Rx 470 Nitro+ 4GB = 29.6 + 148

After modding each BIOS accordingly to the best guides I was able to find, (I ended up with all Samsung memory), I think I was able to max them out at best efficiency. Albeit Pascal adds a lot of wattage, at 10% intensity, it doesn't seem to slow down ETH at all.

Core: 1125
Mem: 2100 - Not sure how bad it is to max it
Undervolt: -48V - I have little knowledge on the effect of undervolting, any advice is appreciated. The -48V helps the Sapphire OC jum from 27 to 29 Mhs, but has no effect on the Nitro+

what do you use as your intensity settings

I take back what I said about undervolting the Nitro+ having no effect. I now see it running at 91.7 Watts instead of 100, no change on hashrate

pretty good numbers.

I have played with  settings for

  - ethi  4
  - dcri  30

I dropped off with eth  from a total of 266 mh to 246 mh
I am getting  over 3600mh for pasc
this is using smOS

Good news... my rig has now been running 24 hours with no crashes and most of that time at -dcri 17.  This has got me up to 912 total h/r (4 GPUs) for Pasc and still maintained a reasonable 107.5 for ETH.  Overall system now pulling 695 watts so still have plenty of headroom with my 1000w Plat PSU. 

I will start trying to push a bit higher and see what happens, but given the explosion of ETH price and continued drop of Pasc, I need to re-crunch the numbers and see if the extra wattage and slight loss in ETH h/r is actually still worth it. I think it is, but if these trends continue, it won't be at some point, so I want to identify where that point is.
