3x R9 280x setup

[mrugala]

Hello, I am considering a setup for a 3x Radeon R9 280x rig, could You suggest me which other parts I should use? To minimize the cost, and be optimal aswell (so the GPU is the bottleneck)?

Assistance from anyone who has similar setup would be even more helpfull

Afaik scrypt mining doesn't require much cpu or ram power so I would just go to newegg and find the cheapest motherboard with 3 pci-e slots (probably 1 pci-e x16 and 2 pci-e x1 would be cheapest). PSU would probably need to be 1000W to be safe.

I thought I do need 3x x16 PCI slots, since this card(280x) has PCI x16?

Has to be pci-express not pci. Can be x1 with powered risers or x16 with risers.

Beware of the heat produced. You will need risers or external fans to keep them cool!

I currently have GA-P35C-DS3R on my old PC, it has 1x PCI-e x16, and 3x PCI-e x1, does that mean I can use 3x 280x which have x16 PCI-e slots?

Your motherboard can support 4 video cards with riser cables.

Awesome! Riser cables only for 1x pci-e slots, right? Is the only purpose of riser cable to allow cards to be further from each one, or PCI-e x1 slots need those to connect to PCI-e x16 card(which I doubt is necessary)?

Beware of the heat produced. You will need risers or external fans to keep them cool!

Do You mean that those connected to PCI-e x1 need external fans, or each one (x16 slot one too)?

For more than 2 cards you might as well just use riser cables for all of them. You need to space them out because they produce a lot of heat even with the built in fans.

Okay, do I need PCI-e x16(female) ---> PCI-e x1(male) cables for PCI-e x1 slots on my card?

Or can I use PCI-e x16 --> PCI-e x16 ones?

really, no one with some helpfull advice?

"wow I'm jealous!" isn't advice but it may be the answer you're seeking. If not I'm sure everyone will walk you through it b/c you're not feeling like using search/google. You should get 1 before you go all in

Kinda late with Your post, also I've seen many guides but in my opinion buying 300$ motherboard isn't necessary at all.

you'll want a 1200W PSU (just to be safe), if you go with the sapphire vapor X's you cant fit 3 side by side on most motherboards, and even if you could they will run too hot, so you'll need risers so they can be mounted elsewhere (and further apart)

I just use an amd a4 in my miners, don't need much cpu and 4G-8G ram.

You don't need a good motherboard just one with enough pci-e slots.  I use the f2a85x-up4 in my miners but that's just because im familiar with the board and I like a few of its features. (its a tad unpredictable with risers though). You can use any type of pci-e slot, 1x, 16x etc, it doesnt matter just get the right risers (e.g 2x pci-e 1x to 16x risers, 1x pci-e 16x to 16x) I have a rig here atm with 3 280x's. 2 in 1x slots, 1 in 16x slot, all powered risers.

Does the slower PCI-E slots affect the hashrate? I mean is hashing faster on card connected via PCI-e 16x, and slower on those connected on PCI-E x1?
