I up my post from a few days ago.
Been mining Zcash since i posted it, stable at 1725 Sol/s. (is it possible to get better hashrate for Zcash btw? and lowering the power cost?)

So hadn't much time to get into it last few days.

I tried mining Zcash getting more or less 290 sols/card without any tweaking and it's stable. I Let it run for a day and not a single problem.
when I tried eth and hashrate was dropping and finaly crashing, i was at PL 70 core -200, -100, +100 (tried a few to see if it changed anything, answer is not from what i saw) and mem+500.
I tried
+100 +800 = crash
-200 +600 = crash
anytime i try to go above +500, it seems it's not stable and eventualy crashes (real pain in the ass, btw)

Since i got no problem whatsoever with PSU when running Zcash, i guess it must be the GPU/drivers that are the issue?
Even with hynix mem i should be able to OC them to get 22Mh on eth i think.

Hi guys,

Anyone with 1060 Gigabyte windforce OC 6G here?

I got 6 of them in my rig. Hynix memory 

I'm pulling 1700-1750 sols on Zcash out of the box. do you have settings to get better hashrate?

Tried eth but i can't OC the cards more than mem + 500 or miner crashes.
I was getting 15,5Mh out of the box, 18,8Mh with core-200 mem+500 but even then it's not stable. i get hashrate drops and crashes. anyone had the same issue? got a solution?
i'm sad because i have another 1060 6G KFA2 in my main computer and i'm getting 24Mh on eth with ethminer. I was expecting to be able to get the cards of my rig to a 22 or 23 Mh due to hynix mem but it seems that's not the case or I have a problem that i'm not aware of...

And what else do you mine with your cards right now? Eth, Zcash, xmr, ... ?

small update here, got the 6 cards showing, i installed your driver (same ones as i have on my computer to mine with my 1060 6G)
I got others issues but fixed it.
Now, i have a new problem. Miner is not stable and it seems i can't OC to what you advise me to do.

here is the problem:

when i let the rig on and mining, at one point i get this :

and/or this :

It's hard to screen because when miner crashes, it's laggy as fuck. It takes me like 3 to 5 minutes just to save the screenshot... next time i'm gonna use my phone and take pictures of my screen like a fucking retard , way faster than waiting for nothing.

I read driver error somewhere (not showing on the screen i think). One time it lasted 4 hours, next time not even 30 minutes.
Do you have any idea what to do?

I don't think it's the issue here. I got 3 cables powering 6 risers. so 2 risers for 1 cable i did that because i read somewhere not to power more than 2 risers if you don't want it to crash.

The errors i get are drivers ones.

it's about 20°C, nothing too hot. Rig is in an open frame i did myself. Cards are between 60-65°. I'm gonna place 6 80mm fans i got when the rig will be set and good to work. I also plan on adding a 7th card, a R9 290 i got earlier, got a space for it but i wanna be sure PSU can handle it so i didn't placed it yet (and i also need to buy PCIE extender slots and a PSU cable cause it's a 8+6 pins).

here's a picture of my rig:

And i forgot to mention, did a test on Zcash, getting 1700-1750 sols out of the box without any OC.

Yeah i know, i don't understand because my 1060 6G kfa2 is working fine on windows 10.

I installed the same drivers, same miner, and i'm getting different results. I know that hynix mem will give a smaller hashrate. But for some reason, i can't seem to OC these cards like i do with the card on my computer.

I'll be looking into different drivers i think. to try and get a more stable hashrate.

I sometimes get error drivers and the miner crashes. i'm gonna need to take a look at that aswell.


No, i didn't have to do that. i'm running on Bios 1.2 and it seems to be ok.

yes it's frustrating lol

Now i'm running 6 cards at core -200 mem +500 and i got 18,8 Mh/s per card, it's low but i'm leaving it this way to see if it's holding steady ^^

if i try to get mem higher, afterburner is kinda freezing and i got errors in the miner.

i still have to optimize that, it's weird because my rig has the same driver (382.53) than my main computer where i have a KFA2 1060 6G (samsung memory core-200 mem +850) and i get 24 Mh/s with ethminer 0.9.41 genoil.

My rig is 6x Gigabyte GeForce GTX 1060 WINDFORCE OC 6G (hynix memory  )

On afterburner, if i try to push it to let's say mem 700 or mem 800, it crashes when miner start to work and when i close the miner and go back in afterburner, he's freezing as fuck and the hole computer too.

once i got a memory error but on the computer, meaning 4G is not enough can it be the problem here?

I solved the problem by simply pluggind my screen on the card that was on the x16 slot.
all 6 are mining now.

In bios i'm on Gen 1. doesn't have the option 4G but since it's a pro btc mobo, i read somewhere it runs it already.

Now i have to try some drivers to find the best hashrate and i'll be good to go i think

Update, I got 6 cards showing.

I unplugged all PCI 1 slots and plugged it again, it's now showing right. guess is one of the riser and trouble connecting, (weird because i checked them all one by one and they were showing right, anyway i'm glad i can moove on)

In the meantime, i encounter another issue.

when i want to launch the miner, i got a Error 0xc00007b.

I had first a MSVCP140.dll missing. i looked it up and i downloaded it and placed it where it's supposed to be,
then i got a VCRUNTIME140.dll error. same here, i looked it up and corrected the error by dowloading and placing the library where it's supposed to be.
and now, i got the error 0xc00007b.

As i was typing this, i found the wonder link : https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

Installed 2015 and 2017 and it was fixed!

Now, another issue appears :

5 out of 6 cards are actually mining. I 've got only 15.5Mh/s out of the box on 5 cards (hynix memory and i will have to find other drivers i think)

I've made some screenshots :

As you can see, miner shows only 5 cards mining. Afterburner doens't show card 1 stats. the card that is not working is on the PCIE x16 slot.
any idea on what to do?

PSU cables are plugged in, again, i tested individualy each card and each of the 6 cards works fine. so that's not the issue.


all risers are working fine since i tested every one when i plugged each card separately from the rest.
In my opinion, it's not an hardware problem, more a software one

i'm gonna try some drivers that citronik gave me on another topic, will see if it works.

Hi guys, i need help with my rig.
Long story short, I have 5 cards instead of 6 showing in windows and i don't know why.

I don't want to hijack the thread so here is the link to the topic I made with more details, if some of you can drop by and offer wisdom, it would be much appreciated.

i'm off but i'll read when i get back in a few hours.

Ty guys 

each slot works fine, as i said, i tested them all. PSU is fine, 1000W is more than enough for 6 1060 cards so it must be something else...

Yeah i forgot to mention, Windows 10 ^^

I didn't find enable 4G in bios, all i found was Gen 1 or Gen 2 in some options but i don't know what it means.

Risers are not the problem since i tried all cards one by one and they are OK and showing when i only put 1 card in.
I think it's more a drivers/bios problem but i don't know what 

Hi guys,

I just got the rig assembled and when i plug all 6 GPU, only 5 are showing. It's not a GPU hardware problem since i tested them all one by one on the mobo.

hardware :
mobo : Asrock H61 pro BTC
PS : 1000W
CPU Celeron G470
4 Gigs Ram
GPU : Gigabyte GeForce GTX 1060 WINDFORCE OC 6G
USB powered risers

I read that it can be a 4G decoding on mobo problem but 4G is not available in bios. Bios is 1.2 version. Last one is 1.4, i tried to upgrade it by using the 1.4 version on a usb stick but mobo does not find the stick. (i booted OS on it so format should be ok). I tried flashing using internet but i'm not connected due to the fact that i'm using a wifi stick.

I also read somewhere it can be a driver issue but i can't find it back.  

In a few words, i need help.

Yes I want to do that to begging with.

I have a KFA2 GTX 1060 6G (85W mining Eth at 24MH/s right now)
psu 750W Gold+(enough to have a second GPU, got an old GTX 660 ti 2G, i'm considering plugging it as a second GPU to mine with it, don't know what it can mine exactly)
mobo is an MSI Z77A G45 ( https://www.google.be/search?q=msi+z77a-g45+gaming&source=lnms&tbm=isch&sa=X&ved=0ahUKEwji0p_B_4TVAhVBLVAKHXZ5DlQQ_AUICigB&biw=1920&bih=1012#imgrc=Hl5WOGKaeFVTqM: )

xhat can i do with that?

I was also considering building a rig, investing in this market, right now i could get a rig of 8GPU 1060 6G for about 3K$, which seems ok. Still hesistating considering the actual downsing on the big coins.
The goal in that would be to first, pay the rig with what i mine, then, mine to hold and make a few buck here and there, start to trade coins, etc...

yes that's what i meant. I wanna start mining, but don't know what to mine in that state of mind.

something easy to mine, to hold for better times.

what coins are the most profitable at this time?
