Monstrous $30,000 Rig Can Be Seven PCs At Once

[Rikk The Gaijin]

I know many of you are not gamers, but this is an insane build, so you tech geeks (Glimpse) should like it

hehe, seen it already, Rikk =) it's actually a nice though I've been talking around here for a while.

& for us, Octane Render, users this could stand as an inspiration. If You would take 7x 980Ti ot TitanXs, instead of those AMD cards, Single Slot mod them, put waterblocks ontop, You can get them into motherboard like this (with Dual CPU) or into something like asus x99 eWS (with single CPU, that still provides up to 7 PCIe slots).

End result? - You may ask =) we would be looking at around 1000+ in terms of OctaneBench. Ek is pushing forward with that 7port bridge simplifying instalation =) overall that's a nice showcase how dense & powerfull system could be due to watercooling =) not to mention noise signature is way lower compared to 7 aircooled GPUs.

we shoud all chip in and

- get a system like this/maxed out gpu system
- a booking system (so you can reserve a few spots per week)
- a license

once we have it, users can send their .orbx for free to the rendersystem and render their scenes.
They would only need to chip in every month, about 3 to 4 dollars/euros a month to pay for the electricity costs.

Extremely cool Rig and yeah it would be nice to do that stuff with some 980Tis BUT as Linus mentioned in video if he used any other card he would not be able to pull out GPUs of Motherboard due PCI-E clip/lock would be covered by length of GPUs so that would be another problem we would need to workaround in Octane Workmachine system ..

Insane, but superb.

Yes, great setup. I posted the link somewhere on the forum 2-3 days ago.

There are some weak points of the build

- too high temps, some say 70C which is crazy high for WC(probably the parallel bridge does not pump water equally high enough to cool gpus, but we don't know this for sure. Linus never said anything about it)
- too few rads - he should have got extra pedestal for S8 and extra 2x360 rads. For 7 gpus and 2x xeons the minimum cooling units is 12 so he should have installed 4x360
- the two dual d5 pumps should be given at once - there is no way one d5 will pump water through so many rads. There is a new EK dual d5 top available for about 2 months saving extra space.

I am glad I saw S8 - my favorite WC case.

no proble with that at all.. lock first & the last or.. use some tools like very small pliers to loosen out thoe clip locks..I have played with single slot backplates & I could say that's not an issue =)

There are some weak points of the build

it's probably due to rad space alone.. those GPUs are pretty toasty & You need at least single 120 to cool them (& the still, temps would not be perfect =) Pluss if You take paralle loop You need a lot of flow as You split stream into 7 paralel flows..

& last but not least, in terms of OctaneRender workstation this could cost way way lower between10-12k =)

Does anyone know if e.g asus x99 e ws with 5960x or 5830k can handle 7 gpus without splitters, risers?

How do you mean lock first or last ? When i put GPUs in my MB (Also Asus Dual CPU) it locks automatically when you push the GPU so for unlocking you need to be able to push it by finger or some tool to pull out GPUs, i..e locking is not optional, it happens automatic on that MB.

Yes, I talked with JJ from ASUS & He mentioned it would be a problem. Anyway that board with pair of PLX is designed for such things..seven PCIe giving 8 lanes each =)
