1060 6 GPU rig, need help

[Gridden]

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.

Try swapping the riser with a new one. Most of the times, risers are the culprit for this kind of problems.

It's interesting. Can someone start 6GPUs on that old platform? It could be the cheapest platform for 6 GPUs

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

Try looking for a "Enable above 4G decoding" or a similar option in the BIOS. If you can't enable it/can't find it/still does not work it is probably Windows 10 issue (if you are using it) or driver issues.

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.

Have you identified what PCIE slot is not detected? I can possibly see that one slot is faulty, check also your PSU running 6GPUS might be in power shortage for a 1000w powersupply.

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...

re-check all your PSU cables...every time I have a card that won't work it's related to the cables and connectors

You might want to turn the PCIe slots to Gen 1 and test the risers individually. If all of them work then I think it's a software issue.

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.

[Gridden]

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?

I had all sorts of issues on Win10, switched over to fullzero's nvOC and its working like a charm. super easy to use and supports the nvidia 10 series. If you have an extra 16gb thumbdrive you can image it over and boot it up off the thumbdrive and see if it works without formatting your Win10 off whatever you have installed on

Are you using a prewritten .bat file, if so check the cuda_devices and make sure it has 0 1 2 3 4 5

Also, this might be a stupid question as i doubt it'll let you boot without it after 3 cards but worth checking all possible problems - Did you plug in all the molex power cables to the board terminals?

in the past i had to ensure 4g encoding was enabled and then play with the PCIe settings (trial and error with Gen1 settings, Gen2 settings, etc).

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

[joshuajones02]

ah yes! I was getting a strange error when i was running IGD as the main display.. it would work great for 4 cards but the moment I put 5 in, everything went to shit eventually I used the PEG x16 as the display and everything worked again lol. glad you're online.. shit is frustrating, I spent a week trying to diagnose a previous problem I had with a MSI board.. was convinced it was everything except the board but it was 2 of the PCIe slots that were giving me issues, so went with an ASRock board and everything was better.. was going to sell it but now I just run it with 4 cards lol..

[Gridden]

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?

[tekno]

4G is enough but with +500 mem oc 18.8 is very small hashrate. try predefined mining OS as smos or ethos. etherminer is very effective for nvidia cards.

[kollom]

meaning 4G

you installed a new BIOS?

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.

[Gridden]

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