Preparing for the Workshop

At the meanwile some tests with two GPUs on ITX
With special riser cards from SuperMicro servers, and some changes in the BIOS, we are allowed to use two GPUs on one little PCIe Slot
Cause I didnt had a bridge (wonder why I didnt got one with my MB) I had to search another solution

That paste any good? I know its new so I haven't seen any reviews for it. It's actually WAY more expensive than CLU or CLP... $20 a pop at my local MC...

Seriously? That paste costs €6 over here. Actually cheaper then most other good paste. That's a massive difference...

Either way, this looks like a promising build. Makes me want to do something with that spare Silverstone ITX case I have laying around

We have a few tests here and it seems to be one of the best. I have the CoolerMaster MasterGel and the Grizzly ones here and both are fine =) The CM MG is around 10 Euro here in Germany

Looking forward to it.

This is exactly what I was hoping to do with this motherboard, down to the exact same GPUs. Looking forward to see what you did to get the bifurcation to work.

At the moment I am working also on a 1:1 instruction to install all the stuff and what (riser, bios...) is needed. (Do you want to test and improve it? Write me on FB)
I would love to, but I don't have the motherboard nor the cards yet. Current system has got to go first. I'm sure the folks over at [H] wouldn't mind helping with testing, though.

Have you noticed any difference between bifurcated SLI and normal SLI in terms of performance?
 
#21 ·
Haha yes I signed up there a few days ago.

No I didnt noticed any difference.

At the meanwile I updated the first post to have all informations there (maybe here will be more action and searching pictures is annoying)

And I also changed the cooler on the Mainboard with a lovely Bitspower one

How tall is that block over the motherboard? Right now running a Predator on my MB, but wondering if its an option for room reasons in the case I will be using (Bh2).

I love that cooler. Have you noticed anything weird about the screw lengths on the block. I read a build log where some guy had to change out some of the stock screws cause they weren't long enough. This is turning out to be the build that I wanted. Check out my sig
