I think that's two bad advices in one sentence but to each of his own I guess. (Though the GV-N75TOC-2GI cards are faulty by design and will die in a few months).
Hello bathrobehero, long time!.
Why do you say that? what happened to you with those cards?, i have like 30 of those for about a year and a half and it was the most stable card i have ever used!, followed by the evga 750Ti ACX FTW which are pretty good too, the only bad thing about the gigabyte GV-750TOC-2GI i had found is that the fans are shit, and so far i couldn't opened it to oil them, like in the sapphire cards and the gigabyte 970 which is tricky but doable.
guys/girls:
I was wondering why so much fuss about trying to use 6 cards?, it is a freaking pain in the @ss do that, usually up to 5 cards is fine but 6 cards is tricky as hell and you overload your power supply.
contrary to what other ppl say, power supplies are not meant to be used at 90% load, i never load my PSUs over 60 or 70% capacity as a result, i have never ever blown any PSU and i have about 40 between 850 and 1100W psus.
but if you insist to 6 cards, the only motherboard i have never had any issue with 6, is the good old H81Pro-btc , but you gonna need a lot of ram too, so again, what is the gain in putting so many cards in one system?.
I found that the most efficient way is to use AM1M-S2H motherboard with 5350 APU, 3 cards and a quite cheap 750-850W PSU 80plus, you don't waste money on expensive PSUs, motherboards or processors, you divide the amount of memory between 2 rigs, and lower the power consumption, as this mobo uses almost nothing of power, is the most efficient setup i had found by FAR.
dunno what you guys think, plz comment.

Hey induktor, long time indeed!
Those Gigabyte cards have some sort of low quality voltage delivery component which tends to die (card won't work, no fan, nothing) but within warranty they change that part to a better one so they'll last the next time - or so I heard.
Maybe it's not the same for all of these models, maybe newer batches doesn't have this issue but there's a lot of complaints about that model and I had 5 or maybe 6 out of 6 of these die in a matter of months but after repair they work perfectly.
Also, while unpowered risers might work, powered USB risers are much more reliable so I wouldn't recommend using unpowered risers (
especially ribbon risers), let alone recommending them to people who are new to mining.
Same goes for 6-pin aux on cards; you can do without but then you have to make sure you don't use too many cards on one molex rail otherwise you might burn the PSU or the molex cables if you draw too much. So in order to avoid having to put more than 2 cards on one molex cable, you'll very likely need to use sata to molex cables which are terrible and not recommended.
With 6-pin cards all you have to keep in mind to have a single-rail PSU and enough 6-pin connectors.
This happened to me on a 750 Ti with no 6-pin.
But if I put 3 cards per molex cable, those molex cables would get very hot so likely they would have burned anyway eventually.
But for cards with 6-pin the sata to molex cables are cold because the cards pull most of the juice from the 6-pin cables which are built to be able to handle it.
I'd also agree that using a PSU 0-24h above 80-90% is probably a bad idea. I mean it's better be safe than sorry.
