3 sets of 6 per row ..

will start 3 additional row on this rack... 12 units in total hosting 72 cards using 7.8kw

Will upload full pix once i have the full rig up and running.







Will make a youtube video on my second rack

The cards are a bit too close for my taste and there's a lot of vertical space wasted but it does look good.

Thanks... I am running ZCASH for the time being .. once i have the rack full i will be putting it back to ETH for good... not a fun thing updating them.

I agree.  I did an experiment about 3 years ago and found that the optimal distance between GPUs was 2.5x the width of the GPU.  The cards were all dual fan 7970s and 280xs.  It may be different with your cards.  However, I can suspect that supplemental cross-cooling will be needed more than the picture displays.

i disagree the distance mean not too much if you are going to put 3 fan in front for pushing air between them, actually it's better to have them close enough to make the tunnel effect better

Almost done the third revision

One step closer. Anyway there's a lot of room for improvement, like:

- custom fan units, 4x92, 3x120, 3x 140 (WIP)
- custom and dedicated PSUs and cable management (WIP)
- extractable plates (WIP), ETA 1 and an half weeks
- 7x VGA plate (WIP), not so far from the final revision
- 2x 2.5" SSD compatibility (WIP)
- frontal VGA compatibility, upon the motherboard (WIP), ETA 1 and an half weeks
- Power/reset/HDD LEDs (WIP), ETA 1 and an half weeks





Some more VGA PORN





It's not just this, but also the first USB RISER PCIE 16x made in Italy. Totally better than the chinese models, tantalum capacitors and MLX, 6 PIN and 8 PIN PCIE compatibility (with custom cryptenergy 12/16AWG cables with GOLD pins, and possibly dedicated capacitors to enhance ripple suppression)

so you copy Chinese riser, and made it in italy ? isn't it just made it more expensive?
and also why still using molex powered, chinese already step ahead with PCIE powered with 12v to 5v step down regulator to prevent Molex/SATA PSU cables burned while using RX series AMD GPU

That pci-e riser is indeed awesome. Can you please find link and post it here? It will decrease so much of hassle for cables .
I checked lhclab.com but they dont have the one with 6 pin pci-e connector

TIA

Due patent I cannot show you the main features, because of it will be used in our solutions.

It's brand new project, we're not using chinese schematics (In the photo I've shown the chinese, in the background you can clearly see the electric schematics.. something really different). It's conceptually similar simply due the fact that this is the common positioning of a VGA; there's a PCIE horizontal slot, 4 holes to fix the RISER, a USB interface and the connectors to power on. It's like saying that Ford it's copying Mercedes Benz due a similar car concept, or any smartphone vendor copying the other one due a thing that you put in your hand called smartphone  Wink

These are some key elements
- the complete different power delivery, apart from a completely different pcb with copper layers and passive dissipation systems in the pcb itself. They will be very high quality, with a 2 year warranty in the EU region (*)
- much more resistant pcb (almoust double layers)
- +12V derived power, not from other methods. This system prevents potential instability, and can obtain an higher A load due more powerful components
- compatibility with molex, 6 pin and 6+2 connectors, for the maximum possible stability
- possible integration of ovp and ocp protection

They will be bundled with our other project on the motherboard, a new typologi of flexible PCIE adapter, that could be linked with other units creating a single, robust, system. They will also have a totally custom typology of heavy duty cables, for the maximum safety and A loads.

The objective is to provide a capable environment for 7x R9 290 on neoscrypt (to make you think about the potentials), with a proper power delivery and dissipation.

*we'll utilize them for our own farm btw, don't expect them to see in the market soon. I was pretty tired about the chinese ones, and theyr general lack of stability and security features, that I decided to go on my own designing one.

The riser you've shown seems surely more capable than the previous, old, one but I haven't tested them so I cannot talk for experience. How long are you using them? RMA/DOA rate?

Keep in mind that such a riser it's just useful if you've got low powered VGA's with ordinary psus. I'll have in my systems custom ones, much more complicated and potentially interesting.

How much are you selling them for and are you in the US? I have been buying them from China but the shipping takes 4-5 weeks so I am looking for something a bit closer.

I would think that it would be more expensive than the chinese made once. I am getting the chinese risers for about $3.5 each. Let us know about your price and pro and con about your risers.
