Title: PCIE splitters to put 8 cards into one rig?
Post by: 2weiX on July 20, 2011, 09:40:41 AM
sup all,


i have 3x6950 and (soon) 1x5830/50/70 to add.

currently all cards have ben risen with (duh) riser cables and are suspended over the motherboard in the usual fashion (ie some strange construction, selfmade).

i was thinking, now:

If I get two PCIEx16 to PCIEx1 splitters and plug them in, use riser cables to connect 4 cards to each of them and suspend them somehow so that I can get them cooled, I could - if I use one or two additional PSUs just to power the cards - potentially run up to 8 cards on my rig, right?

I would "just" need four more cards and two PSUs that I exclusively use to power the cards. No additional rig, motherboard etc etc. Only one remoteadminthingamabob and no more whatsits.

yes/no/cancel?

hmm very interesting idea. maybe someone can be a guinea pig and try this. where would you be finding these pci-e splitters? the only place i saw that has these is here, which i bet will cost a buttload:

Yes they exist but they're year from price efficient from what I've seen often costing as much as another rig.

Well, they work fine for me, but you r right. Cost is really an issue
At their price you can easily set up a mobo, cheap CPU and a single cookie of RAM.

Advantage of having two systems: cheap and easy to build
Disadvantage : double maintenance work, so there is
