I set power lower 65%   about 800 a 1080 ti   room is cooler and pretty stable mining

yeah, skein likes core, not mem... its more math than memory oriented like other algos.  You don't get a ton, but you get some out of it.

Just playing around with my 1080Ti. I've got it running at 916mh without taxing the computer too much(intensity=25).
75% power seems to be the sweet spot for efficiency...power atw goes way up for very little hash gain after that.

80% power=325atw
870mh

75% power=310atw
856mh (best setting)

70% power = 296atw
828mh

60% power = 269atw
760mh

I was able to get those hashrates up another 50-100 just by increasing the core clock. It seems Skein is really responsive to core clock.

Am running smos on that rig which should not have any issues with 6. Am leaning more towards me missing something in the bios not set right. Appreciate the tips!

Are you on Windows 10?  If so, I built 2 6x470s on that Mobo recently so might be able to help.  Firstly, if you're trying it on Windows 7, I highly recommend the still free upgrade to W10.  I tried to build a few 6x rigs with W7 and was never able to get them running smoothly (or at all) with 5-6 GPUs... even after the reg-mod, etc.  Once I went to W10, absolutely NO issues with 6, except of course for the crappy updates that can't all be stopped, but I think I have mitigated that aspect for now anyway.

One thing that I have found works best is to install the 1st GPU (via riser) in that x16 slot. I have done this on both TB85 rigs as well as ASRock BTC R2 and it worked perfectly. Originally, I tried other slots first and it tended to cause problems.  I load the the first GPU to that x16 slot and have the monitor hooked up to it as well on all 4 of my rigs.  After the x16 slot, I do the first (farthest right, closet to the CPU) x1 slot, then slot 3, 4, 5 & 6 in order, one at a time.

If this doesn't work, you might want to try different risers (if you haven't already). Seems like there are a few bad batches of the molex version powered USB risers going around lately as I have like a 50% fail rate on those lately and returned most of them.  Luckily, the 6-pin PCIe versions seem to me much more stable... I am 12 for 12 on those so far.

Am running on zpool. In process of setting up another rig with 1x 980ti for grins (got it CHEAP) to see how it does on neoscrypt.

edit: after tweaking it was only able to get $1.67/day at nicehash.

What pool do you use? At blocksfactory I randomly get share above target error, and after a long search haven't found a way to solve it. Do you experience the same?

Am running alexisminer also. doing good for a few days now

Am running skein +180 core and +300 mem 75% power for 880 mh on 1080ti fe and 660 mh on 1080 fe. getting around 5mh/watt according to the miner 

For me I'm using : 65% power 275 core, fan your choice this on NVIDIA GTX 1080 TI. Got it running for days without any issue.

Can you link your miner client? You're still doing more hash than me with lower core settings, as far I know memory overclock doesn't make difference for me.

I got it going  and I do a bit less then 1000 per 1080 ti.

Skein pays okay better then ZEC.




So I can run 0 core and 0 memory I will give that a try.

Hey guys, I have a tb85 am trying to get 6 gpu going on but every time I populate the x16 slot with riser the others are not seen. I KNOW it is something stupid in bios I am overlooking, but have been trying for a couple days now so would appreciate a little pointer. Thanks!

Somebody with skillz in this needs to write y'all some tuning optimization tools so you can seize opportunities better.  You guys seem to know your danger zones on variables, so set 'em and let it explore within said ranges.  Run 24h or so maybe, there's your settings for a bit.  No, it isn't me, just an idea.

I am doing skein again  along with zec

1.7.3 for skein  is doing 950 per 1080 ti

any settings info would help

I am 65% power  125 core -300 memory 75% fan


changed to 70% power 150 core 100 memory 75% fan

I got a bit more hash.

man where in the world did siacoin come from!!!
that thing jumped so much in profit over night

For the nVidia, it is quite good.

Anyone know if MSI afterburner wattage readings are fairly accurate?

The 378.13 Driver limits to 6x GPUs.

this ASRock H81 PRO BTC or BIOSTAR TB85 build will OC 5 of the 6 GPUs on a MSI Z97 Gaming 5.  Getting the sixth to OC can be done by editing the xorg.conf file, or patching it using this process:


I used to have an MSI Z97 Gaming 5 ( I sold it to a friend who primarily uses AMD cards (as he can use all 7 slots) ).  I think I have an old image I could modify for you have trouble getting the sixth card to OC.

This usb does ~130mb/s sequential read and ~25mb/s write, its read speed is on par with most HHD.  Just because most usb keys are slow; doesn't mean all are.

try -35% power  85 core 375 memory
