Yes, I used all three slots. I have 6 risers plugged into 6 PCIe slots on the board, the 1 to 3 splitter plugged into the 7th PCIe slot, and 3 risers plugged into the splitter. Note that the 1 to 3 splitter is powered. I believe it has a Molex connector.

how many cards can you stick into the splitters - its has 3 slots - did you use all three?

Awesome, thanks for the info! Already have one of those on the way and I'll be buying two of the M.2 adapters since they're so damn cheap and trying those as well.

I am using the latest MSI BIOS. It was my understanding from my research that the "hacked BIOS" was created before MSI introduced the latest BIOS and was thereafter obsolete. I didn't make any other changes to the BIOS other than selecting the settings noted in both of our posts.

I am using the 1 to 3 PCIe splitter. It comes in a blue box, and it looks like all of the Amazon and eBay vendors are selling the same product.

Are you using that modified BIOS that's floating around or did you tweak it yourself?

Are you using a 1->3 "splitter" or a M.2 slot adapter?

All I can say is that my boards are stable for weeks at a time running 9 RX 470 4GB cards. I haven't tried 10 cards because my rigs have been so damn stable with their current setup, I didn't want to risk introducing new issues, especially with mining difficulty increases as of late, since the prospect of obtaining additional RX 470s at a reasonable price appears to be minimal at best.

I have a vague recollection of Tytanick mentioning that smOS can handle up to ten cards, but he needs to update scripts before it can handle more, though I may be way off base with my recollection.

I am getting very inconsistent hashrates in smos using Claymore. I have 570s that hash at ~29 MH. In Claymore in smos I am getting a very inconsistent readout jumping back and forth from 29MH and 19MH (and sometimes somewhere in between). Anyone else experience this?

Also, I'd like to try sgminer for eth, does smos support that? I only see sgminer for cryptonight, pascal, and nicehash in the beta dashboard.

Will it work up to 8 or can it go to 9 or 10?

hi, today i received my m.2 to pci-e adapter and tried them out on two of my cards, when they are pluged in 2 of the 4 remaining cards that are on the regular pci-e slots go nuts, the cooler jumps for a minute to 100% and repeats that every couple of minutes...when i plug all the cards back to the pci-e slots the coolers work like they should..any ideas?

Glad you were able to get this mobo working with 7 cards. Your instructions are substantively identical to mine from over a month ago (https://bitcointalksearch.org/topic/m.18423032 and https://bitcointalksearch.org/topic/m.18756984). Sorry for not pointing this out earlier, but other commitments (i.e., yard work) have been taking up all of my free time as of late. For whatever reason, there were a handful people who simply couldn't get their mobo to work for  5+ cards, so don't be surprised if people report back that your instructions don't work for them.

Also, this board can handle more than 7 cards.

Perfect, cheers.

I dont support any wifi or modems
Only Normal Ethernet cable.

You need to save original bios, modifu under polarisbios editor (copy 1500 strap to all above) save, flash, reboot, and then try to overclock memory to 1980-2100 - you will have much more like 28MH.
If you want 29+ then you need custom timing strap for memory (not dummy copying) .

Lower the overclock on that card.

I have a problem. I have 6 rigs but only 2 of them has trouble.

GPU1 hangs in opencl call says always. what should i do ?

Thanks Decay!

We stand by our gear too if anything goes bad. We're happy to replace defectives.

Dumb question:

I have 2 x MSI 480 8GB X graphics cards, getting around 24 mh/s out the box. Wanting to overclock to get closer to 29 mh/s. I presume I do this via the overclock settings in simple mining rather than on my windows dual boot?

I changed the core on simplemining to 1095 and the memory to 2000 and saw no increase in hash-rate...

Tytanick say:

If we will pay for your OS, can you add function to change pool, coins for each rig on one mail account?

With multiple jobs tugging at my time and a significant adversion to downtime, I just couldn't afford the extra time needed to continue tuning.  I had so many GPUs come in that I didn't have a test bench anymore! With 5 z87 boards maxed out at 7 cards each that were super stable, I was just going to see if I could find a few more. Thanks again, you've given me the added problem of having to find a few more gpus in order to max out my z170a boards!

Now, if I could only get risers to stop dying on me.  Between some junky new USB risers and the old ones I have from 2013, it seems like anytime I have to move or reboot a system, there's a riser issue. I've been meaning to say something for a bit but I wanted to give a shout out to the guys from Miningparts. I just bought a bunch of new risers from them and they're my go to when a gpu starts acting flakey.

One last thing for all the guys asking about power, I was trying to understand the difference between what the cards were using versus what I measured at the socket(efficiency) when I found this great resource for power supply sizing:

http://www.coolermaster.com/power-supply-calculator/

I've been buying 1200s for my 7 GPU systems but this is saying a 1k should be sufficient.  That jives with what I've been measuring at the wall on my maxed out rx470 systems so I'm trialing a couple evga G3 1k power supplies.  If that works out, it'll save me about $100 per new build.

how can i connect to internet on simplemining os ?
i am using mobile modem or wifi
