Motherboard designed for mining, and better riser cables in this thread.

[TheWoodser]

Newegg is showing a product for the ASRock H81 Pro BTC LGA Motherboard.....

While it shows "Out of Stock" it does have a price of $59.99

I can comment on the USB 3.0 riser cables. They are much better than the old ribbon cables, plus allow you so much more creativity with mounting cards.

Sweet rig!

So if I wanted to use the USB 3.0 riser cables (to allow some creativity in the build) along with the new ASRock H61 mining motherboard that's posted in the OP, would I just use the powered risers as designed and not plug in either molex on the motherboard? I'm assuming so but want to be sure.

Thanks for the thread, ssateneth. Very cool.

Mmm, that's a tough one. I had a really, really, really old AMD ASUS motherboard, like socket 939 old, that had a molex plug for the PCI-e BUS (think SLI was almost brand new on the block then?) I think it was a A8N-SLI deluxe or something similar?

Anyway, that board would not work at all unless the molex plug was plugged in. The ASrock might be the same. FWIW the USB connection doesn't carry any voltage at all, so it shouldn't hurt either way.

Yeh awesome rig mate.. love the clean layout!

I'm scoping up my first dedicated miner and now thinking 6-gpu's is the way to go... 6 x 270X's given my available prices here in AU

I'm also going to go for those USB3 riser cables as there's a guy selling them here on ebay for $AUD25 with low shipping fee

Any updates on where this asrock mobo can be bought?  I am in the US.

[boniggy]

OP still hasnt answered the question about where he got the rig case from. Its awesome and I'm currently at the stage for looking for stackable rig cases.

Come on OP deliver..... or possibly.. did you make it yourself? if so do you have any plans or specs?

Op wasn't the one who posted that, that would have been me.

Completely custom, you couldn't buy one if you wanted right now as I'm working out the final kinks. The last few parts I need are coming from digikey tomorrow, so expect to see the cases for sale late next week.

Thanks!

It even looks like they have pci-e presence shorts built onto the boards, though I haven't had to mess with them or pci-e presence pins on msi z77-gd65 and z77-gd45 mobo builds.  

Thanks for the thread on the latter mobo, btw 

this! is lovely!

Indeed... this is a lovely rig.

Damm that's a really nice post op. I was working on my 270 build and how I was going to place stuff. going to order some of the usb risers now. As it solves a lot of issues. For me that is

I read about fried Asrock Pro BTC boards when people used them with powered risers but also heard claims that without powered risers only 2-3 cards would work.

I'm planning on building a rig with an Asrock Pro BTC mobo in mind with 5 cards, but with 2-3 types of video cards, with different power consumptions. So what would be the safest route to take?

Always use powered risers and if you don't understand what I just wrote, let me put it a different way..............................

ALWAYS FREAKING USE POWERED RISERS!

There!

Get it?

Got it?

Good!

My $.02.

[DontMineMe]

Those raisers are so over priced ! It's almost cheaper just to buy used motherboard with 2 PCI e x16 slots,cpu,and ram off ebay! Or maybe not?

Not for the asrock H81 Pro BTC motherboard.  It provides supplemental molex power to the PCIe ports already, so powered risers would be redundant and likely to cause a short circuit as described in threads in the past.

What?

No, just no. Powered risers will never cause a short with the pci-e lane, no mater if the bus has supplemental power or not. 12V is 12V. 

I'd go a step further and say never use ribbon riser cables, but if I were to use those pieces they would certainly be powered. LostDuchman knows what he is talking about, use the powered ones no matter what mobo you use.

[bathrobehero]

Well, that was not really helpful.

I mean I don't want any fried parts or burnt cables or anything, but google gives a worrying amount of results about fried mobo's which had supplementary power connectors and was used with powered risers.

Really? Find me one.

Or better yet, explain your theory as to why it would cause a motherboard to burn up. You know that the supplemental power is in fact supplemental, and the pci-e bus likely still gets 12V power from the 24pin ATX connector, right?

I myself have run powered risers on supplemental powered motherboards just fine. I also know that paralleling 12V connections simply doubles the current carrying capacity and not much else, but whatever...

[radi324]

I bought myself 3 of these powered risers, hopefully they'll work fine:

http://www.ebay.co.uk/itm/191019533579?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

PSU: Corsair AX1200
Cards: 3x R9 280x (VTX3D)
MB: ASRock 970 Extreme 4

Got non-powered risers but returned them on arrival after I read some more info
