Hey Smicha
Do you have the specs of that machine? or the post? I'm thinking of building a new one...
Im running into issues with my machine where it won't boot with more than 5 cards if i install the 6 it won't boot....
think he's going supermicro route.. problems with 6 cards only? (cheap risers, cheap mob + other things like power delivery are the first things to inspect..)

Amfeltec for 4 and 2 internal so that eliminates the above. ideally i was thinking of getting another amfeltec 8 external and 2 inside but can't as i can't boot with 3 internal and 3 on the amfeltec... won't let me with more that 5!!! any combo of 5 works with the 6 i get no boot...

The "Cluster" solution is not reliable, go for the splitter. Those cluster boards have electrical grounding problems and fail randomly. trust me i have had 4 of them!

Hi Asher,
How did yours fail? Did you lose power for the whole board each time or would individual cards be affected?

Would really like to hear expereinces about the amfeltec board too. I'm thinking about buying one of their GPU clusters for my rendering setup.

Hi Kandori7,
How was your rig build going. Hopefully you are getting good results.
By the way, here are some other forum threads that deal with multi-GPU rig, splitters. Amfeltec, etc.

The following thread may be of assistance to those who for whom a system with up to about six GPUs may be completely satisfactory:
