@ megaplage / induktor - Have you guys try changing SWAP to 24000 vs the min of 16000 that Claymore recommend?  I find it helps makes the 1070 more stable.  It was a pain in the @$$ back when I got it and it was new and required special drivers, certain windows patches, etc.  H81 BTC pro only have 6 PCI Slot, so how did you test 7 GPU config on it Induktor?  I don't think the pci splitter will work well with all cards types, I have 1 and didn't use it for that reason on the H81.

Phil - back to using risers?

In the Biostar manual, found this:

•   4 x PCI-E x16 3.0 Slot(x16, x8, x4- from SB, x4- from SB)
•   3 x PCI-E x1 3.0 Slot(2 slot share PCIE port w/ PCI-Ex16@x4)

Looks like there is some port sharing -- so 7 active slots is probably not doable for this mobo.

I have 6 rigs with this Biostar Racing GT7 ; 4 x GPUs -- no risers. Very stable but for 6 or 7 card format -- I rather go back to using H81 boards or that Biostar equivalent/clone. Anything beyond 7 x GPUs will be too complicated and you better off just getting a Pandaminer (8 x 480Ms)

update on the biostar racing 6 gpu experiment:

so i tried 5 cards first two nanos and 3 470s
disabled audio set all pci-e slots to gen 1

 but only two cards work others show the dreaded
not enough resources error , i just updated the the biis and
it was old 2015 bios now the latest bios loaded all the keds light up
so that bios was really old.

4
rebooted and i found it killed my windows install reinstalling now but i have a bad feeling
about this one

I  ordered 5 of these for 175

with tax  187 or 37 bucks a mobo    cheap  but 4 card max

stil 37 bucks is cheap for four cards




I have this coming

109  but should do 6 cards


I will post results on both mobos  by next friday.


with smOS   you no longer spend a lot for os.

37 for four cards is really good.

I have rethought  how I will mine in the future.

so the cheap b150's  look good to me.

speaking of mobo's, so far for a 6 GPU rig best is to use BioStar TB85, they cheap & good.

btw, they have a new version that supports LGA 1151 dubbed TB250-BTC

@ m1n1ngP4d4w4n - MSI Gaming 5 works for 7 AMD cards no issues.  I have 7 x 470, 7x480 running on them.  No issues and on over 35 rigs.  I only use ASROCK H81 because I had them from legacy 390 rigs and bought more for the 6 x Fury rigs as they're FATTER so I can only fit 6 vs 7 into my server cases.  I would not recommend buying used ones as I have over 40 of these Motherboards and the ones that have flakey slots or randomly dropping slots were the used ones.  Perhaps that's why they sold them.  That was definitely extremely frustrating.

@ Citronik - Can you check the Bios to see if it have the setting for PCIe speed and choose 8/4/4 and Gen 1 or Gen 2 to see if it makes any difference .  I really like this board but I have no interest in doing 15 x 4 GPU rigs.  Maybe 3 of those in worst case scenario and 1 or 2 Wall designer style rigs.

exactly, not sure if it is memory but 1070, won't do more than 6 card, i tested it on H81 pro btc, 1060 3GB version works with 7 cards, but not 1070.

does not work with 8GB cards - memory size barrier

Never tried NVidia with that MB, AMD works w/ no issues.

@Tasty Potato - I think you mean driver updates vs BIOS updates.  Most of us won't use Relive drivers as we're using MOD Roms.  So we'll be using Pre Relive drivers, any of the few right before Relive would do for RX400 series.

@ m1n1ngP4d4w4n - You missed the part where I only paid $61 for them.  Crazy Sales and in America we only pay $150 for TV.  The rest of the world pay the crazy prices.  =)

@ Citronik - All my GPUs are LGA 1150.  Why don't u move 3 of those cards over for a quick test?  Surely you have some spare risers..........LET's DO this ,  Why would a VENDOR make a 7 PCIE slots MB not able to handle more than 4 cards, sound very silly to me but then again anything is possible.  I mean heck, they even made power via normal power button difficult where it's not really well documented.  I don't even know how Philipma knows it's on P 15.  There is simply no reference to the on / off power button on the Layout picture in their manual.  That's some funny @#$@#$ to see you use Chopsticks to hold those GPU in place. hahaha

my DIY of SRR but i call mine Mining Control Center (MCC)

for 8 rigs

4 rigs, i call it the mini version, all sticks nicely onto the acrylic plate.

web interface

mobile interface

parts are very easy to find, not difficult to build them but for the coding most might have a hiccup. i do not have to spend a whopping ermmm over USD 100 + shipping ?

i'm not saying SRR is not good it has a very well written software + support from tytanick, but imho opinion, it's way overpriced.

LOWEST cost MAX profit would be my main goal.

SMOS is great software but again i do not like my miners to go thru someone's server & have the possibility control my rigs or what is happening in the background. just personal preferences.

now here's my magical question, your miners does go thru the "devfee" mining session rite ? does it go to the actual dev or it goes to the other OS dev ?

on my miners page, it goes to the OS dev but nope it goes to me ! Nothing against the ori DEV or any DEV's , it's something i bumped into & i only use it for my OWN personal use & experiments in learning more in mining. PLEASE DO NOT PM me how I do it or share.

OP, here's another angle of the "lucky7" rig i made, i think i should have more close ups of it though, if i see it i'll post it up.
*i recalled someone PM'ed me abt this build, sorry i did not reply to your PM but as you can see pretty clear the parts list in the pic)

Someone asked who sells rigs ? yes I do but at the other part of the world as I'm located in Asia, me & citronick are neighbors, hey citronik, remember me ? Maybe for smaller stuffs yeah, but the whole rack, ermmm shipping would cost a bomb me thinks.

Just delivered a rack of 3 rigs to 1 of my customer. more to go, the racks will have a new revision & looking forward to build "cleaner" rigs.

lastly, speaking of mobo's, the GT7 is freaking NICE, looking fwd to get 1 of those to play with together with the "new" Nitro's 470D4GB as a fun rig, well maybe but the GT7 is really nice mobo.

here's my latest "experiment" with the famous Gaming 5, no time to mess with it yet as the part just arrived & busy building rigs to get them delivered.

*apologies to any dev's "if i have offended" anyone of them, i'm not stealing any "devfees" but i'm learning & i PAID long enough & i'm NOT trying to sell my product over someone else's product but it's really too expensive imo & again, i always prefer NOT to let my rigs to go thru any other servers before the pool as I do not know what's happening behind the scenes*

Happy mining to all, more pics & updates to come.
