I have an issue with my GPUs.
I have 4x Palit 1070 Super Jetstream NE51070S15P2-1041J.
After some mining time one the GPU is going offline and PC is seeing only 3x GPUs after that.
So you can continue mining on 3x GPU only.
To bring back 4x GPU you need to unplug this offline GPU, power on PC, power off PC, plug in GPU.
Only after that the PC will see it.
What could be the issue here? Maybe too much Core Clock or Memory Clock?

I set up -40% power limit, 90 core, 400 memory

UPS on a mining rig makes pretty much ZERO sense, if your electric is unreliable enough to actually need a UPS you're probably going to have your internet going down anyway - and no UPS can stop THAT.
The cost of a UPS that can handle anything over about an 850 watt rig get high FAST.
For example, every consumer-type APC 1500 (and even the professional models for the most part) are rated in the 850-900 WATT range - the "1500" is a VA rating, and ASSUMES no power factor correction, which is quite reasonable for virtually all non-80Plus power supplies ever made for computers - and even the CHEAP stuff by people like Cyberpower tends to be in the $150+ range for a "1500 VA" unit.

Okay thx!
ive been playing around with the 570 i can almost get 350 hashs out of it which isnt bad at all
its more profitable to mine equilhash with it than mining ethash!!
its a little heavy on power tho atm 160ish at the wall

350 is good power at 160 is meh.
But what did it cost?
Was it 8gb?
Did you flash bios?
I can get a 1060 to do 315-320 using 100-110 watts but I spent 220 for it.
its a flashed bios
i going to try over the next few days to get it down to 120ish if i can
i paid 207 from amazon
Just switched my 1080ti to zpool. What clock settings are y'all running for skein? Thanks
Thanks for the answers y'all!
@fullzero Does your OS support the MSI Z97 Gaming 5?

Hi! I want to buy Uninterruptible Power Supply for my mining farms. One UPS for each. Each mining farm have 5x GPUs.
Did someone bought UPS for that? And how is that? Does it makes sence?

Does anyone know the most efficient card for ETH?
Would it be the 1070gtx? (28mh/90 watts)
Would it be the 1070gtx? (28mh/90 watts)
I never saw 28Mh out of my 1070s at anywhere near that low of power usage - but in fairness I never really tried to optimise them for power usage on ETH, and they certainly hit 28.5 (or a bit more on the Gigabyte full-length cards) easily enough.
I think around $200 RX470 is still the best ETH card, best bang for the buck.
Try finding ANY RX 470 for that low any more - they're drying up fast and getting pricy, along with the RX 480.
RX 570 seems to have taken over that point though on ETH.
On the other hand, my R9 290s are still chugging away on ETH and I'm pretty sure both rigs are paid for in full and then a bit, despite the rather high power cost of running those cards....
i confess.... my group made a timely decision to pull the trigger on 210 pieces of the last RX 470s on earth for our 2nd 33 rig GPU farm....

But it really bogs my computer down, I tried underclocking the cards but it still lags badly.
Will have to stick with EWBF for now , I can still use the computer running that.
Stats for 2 x 1080GTX :
Try turning intensity down - underclock don't matter on loading the comp.
I'm getting 540 on a single https://www.newegg.com/Product/Product.aspx?Item=N82E16814125880 at 80% power (160 watts), +150 cpu, 0 memory in afterburner, so seems like you're hashrate is in the right ballpark for your pair of cards.
As far as USB keys go - they ARE a lot slower than any reasonably current hard drive, much less ANY sata-interface SSD - but they're fast ENOUGH to run a mining machine on, CHEAP, and it's trivial to "clone" them so you have a spare around if one dies.
I'm seeing decent Sandisk 128MB USB drives at WALMART for less than any decent current HD, and those are severe overkill for most mining machine usage (I think they also carry the 64 and 32 gb versions of that USB drive for quite a bit less, though not quite down to the $8 of that Lexar - Walmart USED to have the 16GB Sandisk as well but they seem to have discontinued that after selling out their last stock at $10 or so).
nvOC is for fast 16gb or larger USB keys only: I highly recommend using this 32gb one as it is now cheaper than the 16gb one: https://www.amazon.com/dp/B00T61JM4E
curious as to why usb sticks only. not that i am against them, my freenas box has been running off of two 16 gb usb sticks configured in raid 1 for its OS for a few years now.
it just doesnt work with ssds? or..?
Note amazon lowered the price of the 16gb ones back down to $8 so they are the best to get again now for nvOC:

Originally it was a bug that happened when I switched oneBash to be on the windows partition (windows partition is not properly recognized until opened in a file explorer when using an SSD or HDD ( this can be fixed by editing the /etc/fstab file) I didn't notice it until someone else told me their oneBash wasn't autolaunching on boot ( as I had already switched to all usb keys).
This can also be resolved by copying oneBash to the primary partition and altering the absolute path in the 2unix file located in the home folder (this is what launches oneBash). However, after consideration I decided I don't want users to be spending extra money on SSD's for no reason. Explicitly not supporting them is better for everyone long term.
This is my reasoning:
I can understand users who have used slow usbs in the past being skeptical about usb key performance.
The 16gb Lexar's I recommend are very fast (watch one of the nvOC demo videos if you don't believe me)
are very cheap: $8
are easy to attach to image then remove and reattach to a rig
and vs a regular SSD or HDD allow you to use at least one less cable on your rig.
Finally using a usb key allows users to try nvOC without needing to install over their previous OS (no commitment needed).
One more addition option for this USB is store your bitcoin on it!

Well, I finally broke down and sold a few ETH coins at $101.50 (to cash, not BTC). During the last 2 weeks with those couple of scary down-swings, I swore I would sell some if it broke $100 again so i kept my word to myself lol. Now sure, it may be $120 by tomorrow morning but I have got to break myself out of this crypto-hoarding mentality lol. It's just so hard to sell during what seems like a bull market, but I gotta start taking some profits, for peace of mind if nothing else. I am still probably a bit over-leveraged on ETH, but I really like a lot of things going on with the Ethereum network (like Enterprise Ethereum Alliance, and a lot of other coins either on or moving to ETH network. Hopefully this will also embolden me to start taking profits on some other alts... but i doubt it lol.
edit 1: and of course, in the few minutes it took to write this post, ETH went up another $4 lol! So be it... just gotta be happy since in the grand scheme of things, I never could have imagined ETH even at $50 much less $100. When i started mining in 6-7 months ago, it was $10 lol.

Well, you weren't kidding about $120+ the next day. I feel you though, I remember selling 100 ETH at $10 each... lol

I sold a coin last night 1900 plus is hard to turn down.
I spent a few hours in the loft of the solar array trying to lower heat.
I will photo and post later in the week.
I got the katana temps under control.
Strong exhaust fans did the trick
I will post in the katana thread later.

Just switched my 1080ti to zpool. What clock settings are y'all running for skein? Thanks
stock. Power isn't a concern for me. I haven't heard of any boost other than slightly lower wattage... so, I leave it alone.
I push mine pretty hard, and have found it's all about core clock
Power limit ~90%
Core clock +250-300 depending on mining algorythm
Mem clock -300
Fan speed set at 80%
I aim for temps in the low around 69-72 degrees

With good customs roms, 28-30MHs at 100w, is achievable easy.
https://www.cryptocompare.com/mining/sapphire/radeon-rx-470-ethereum-mining/
what brand/models do you use to achieve stable 28-30MHs with rx470 ?
To be fully stable and avoid rejects, I'm generally closer to 27MHs.
with custom roms, sapphire 470 nitro OC 4gb, hynix memory even 29.XXMH no issues on Windows.
on smos, 27-28MH easily achievable, cool and about 1000w only 6 x cards - for 470 thats quite an achievement.
Thats why the 470 is easily the likely mining card winner and also hard to find.
BBT had tested RX570 doing 168MH on smos on custom roms.
What are your settings ?
-100mv , 1900 memory and 1000 cclock ? or higher ?
Thanks....I got it working.

U need to trim down intensity on ccminer using the -i flag to the point you are comfortable with usage.
intensity will vary between algos; but you will see a noticeable dip in hashrate when lowering mining intensity.... be prepared for that.
Got it running soooo much better. Adjusted -i to 25 and also increased my pagefile from 16gb to 48gb (win7 x64).
currently running at 1215mh with 2 1080's so only lost 100mh/s.
Thanks Man!
Can somebody save me from experimentation please?
LYRA and Lyra2RE2. Do they differ from equihash regarding OC?
High core, low memory, low power limit?
How low/high?
