Hi Mike,

which rack did you order at amfeltec and how much did you pay for it?

Hi,

I ordered one cluster with 10 ft cable and 2 channel host card
for about 450 USD. SKU-078-21
I have no experiences yet and still hope, when I get all that stuff,
that everything will work.

I hoped initially with this post to get feedback from guys
already using this amfeltec-cluster.

regards
Mike

Just wanna share, Amfeltec cluster is good solution for me right now, the cheapest way to achieve an external gpus .
I put 4x old GTX Octane on it hooked up to my PC. regarding the transfer speed, I think it's reasonably quick though. Actually it is not disappointing at all.
btw, I've got a new update board of that cluster from them at no cost. It seemed more stable and solid board. I'm happy with it :D

Hi rfox,

Cluster from Canada arrived today.
Still waiting for the Grafikcards.

With adding one cluster only - I still need that Molex-HD-Cable which connects from the
cluster-host board to the main PC as well?
I'm a bit confused about the need of 3 Power-connections.

Hi Glimpse
I'm really interested to your solution.
I ask you where is possible to buy in Europe the Amfeltec Backplate (I suppose you've ordered SKU-076-01, correct?).
Also is interesting to know how the board are seen and managed by the OS. Can I switch them on-off from Octane in the usual way?

Thanks and sorry for my newbie questions...

Mike,

are you ordering dual or more host board for your cluster? if yes, so i think yes...you need molex to be connected with power control cable which is connected to cluster backplane.

you can download assembly instructions (PDF) through their website : http://amfeltec.com/products/downloads/ ... ctions.pdf

Hi Ron,

yes, got all built and it rendered already for about 30 hours without any problems.
With these 4 x 780s OC there is really a great speed improvement.

The last 2 days I suddenly got strange win 10 blue screens (dpc watchdog violation)
Not sure why this happend, maybe the nvidia audio drivers which installed beside the realtec- don't know.
I deinstalled all nvidia drivers other than the pure display drivers an everything seams now
to work again. I hope.

The cluster is really a big time safer. Reduced render time for 1920hd
with motionblur and dof etc. from 6 to 2 minutes per frame.

So I'm happy with that config.

regards
MIke
