Title: Two motherboards? Post by: fishy on June 23, 2013, 04:39:21 PM Is it possible to hook up a set of two motherboards so I can run more GPUs?
"Linking" the motherboards? Or will I have to run a big 8-slot MOBO rather than two 4-slots? Title: Re: Two motherboards? Post by: notlist3d on June 23, 2013, 05:11:32 PM Run two motherboards. Honestly i dont think you want 8 cards right together, sounds like a lot of heat and pains compared to two rigs.

What do you think is the most gpus I can run without the mobo and other components exploding, catching fire, etc.? Title: Re: Two motherboards?

Or will I have to run a big 8-slot MOBO rather than two 4-slots? Why would you rather have two mobo's linked together instead of having two separate systems ? I might suggesting looking into PCIE backplanes instead for what I reckon you are trying to accomplish. Title: Re: Two motherboards? Post by: fishy on June 24, 2013, 11:13:31 AM 801, https://bitcointalk.org/index.php?action=search;advanced There is no definitive number. AndrewBUD's motherboard fried from high power draw with only 4 GPU's. It all depends on your setup, with the right setup you could run 802 GPU's or more. Wow. 802! :o Title: Re: Two motherboards? Post by: ks3rv3rg on June 25, 2013, 01:49:04 AM I was always surprised to see that those pcie backpane things arent used more. I do realize however that theyre pretty expensive.
Title: Re: Two motherboards? Post by: ReCat on June 28, 2013, 01:53:01 AM There is no standard for linking mobos, but some high end servers allow it. That being said, it's proprietary, undocumented, and obscure. Unfortunately, there is no good way to link mobos. Your best bet is getting two 16GB flash drives, and using that to host the OS, so you don't have to have two HDD's weighing you down.
