Reference list of mobos with 8 OR MORE pcie slots

[mrb]

I curated a list of all motherboards with 8 or more PCIe slots. I have full frontal pictures for hardware porn addicts

Cool idea - I would suggest maybe making two lists, one with the 8 or more PCIe slots, and another list that was for 6 or more PCIe slot riserless boards.  That way you could include things like the Onda D1800, which is definitely a mining board but doesn't get lost in the clutter of the riser boards with 6 slots.

I like to see the 8 X 16x PCIe slot. if I'm using the small dimension of GPUs or middle, maybe I can make a custom rig with Mountrack cashing. Nice share mrb, I would try to get any info of those 8 X 16x PCie Mobo.

it's very cool, but I don't have enough an experience to build more from 8 GPU on those Motherboards. I still think how method to reduce a heat every GPUs an adjacent. the split the Power PSUs if I only have a maximal 1200W PSUs, how many should use relay tool such add2psu.

moreover, I have different GPU series and Brand, I guess would have a bit complexity when settings.

[mrb]

Ok I added the Onda D1800. I think mobos like this definitely deserve a spot on my list.

I also added my personal favorite: the ZRTK-21613 & ZRTD-101, which is a backplane with 9+1 slots and the actual motherboard is just another card that plugs into the "+1" slot. So when the motherboard fails, it's easy to replace, and the backplane has a negligible failure rate. No risers. Slots are spaced 50mm (I believe?) so there is a 10mm gap between GPUs.

ZRTK-21613 motherboard & ZRTD-101 backplane:


That same company, Zrt Co Ltd, makes a case as well, and sells fully populated miners with GPUs (https://zhiruitong.en.made-in-china.com/product/jyoEvXaGXUWp/China-Eth-etc-Zec-9-Pcie-Slot-Miner-Plug-with-8-or-9-GPU.html) They are an OEM. Others resell these miners, for example: GigaWatt Alpha 200, and Bitmain G1 miner (whatever happened to the G1 by the way? It sounds like it was announced but they never got around to actually distributing it?)

Thanks bro.

I added the INNO3D motherboard with 9 slots. It's a motherboard+backplane configuration very similar to the ZRT except the motherboard is in the center, which makes more sense from a PCIe latency viewpoint. Cooling a chassis built around this backplane is also more even and a bit easier thanks to the mobo in the central position.

[mrb]

I found out this Inno3D motherboard is a actually an OEM/ODM product, seemingly manufactured by Sunfa. Model number 6299-FA355: https://www.alibaba.com/product-detail/9gups-9-pci-e-16X-slot_60728424903.html

[mrb]

I added 3 Supermicro boards. They are typically not very popular due to high cost per PCIe slot, however the dual-socket makes them attractive for concurrent GPU+CPU mining (eg. CPU mining Monero + GPU mining Ethereum.)

[mrb]

I added the K17, a model that preceded the K37. I actually can't find who manufactures them, so I'm marking them "OEM". K17 seems to have slightly less clearance between the PCIe slots than the K37. But the biggest differences are around power:

• K17 has six 6-pin power inputs (by the CPU area), and one output per slot.
• K37 has eight 6-pin power inputs (by the CPU area), and two outputs per slot except the 2 slots nearest the CPU which only have one nearby power output (so cards plugged in these 2 slots, assuming they all require 2 power connectors, must be powered straight from the PSU.)

Edit: actually K17 rev 1.0 has the power configuration I describe, but K17 rev 1.2 has as many power inputs/outputs as K37: https://sc02.alicdn.com/kf/HTB1gOeLojnD8KJjSspbq6zbEXXaL/231649078/HTB1gOeLojnD8KJjSspbq6zbEXXaL.jpg

K37:


It's really convenient to power cards straight from the board, cable management is a lot easier:



I hope they do have really thick PCB traces able to carry all these amps...

[mrb]

I added Shenzhen Zrt's ZRTK-21612 which, incidentally, is the company who designed the PandaMiner motherboards (such as model ZRTK-21611). 21612 is clearly inspired from 21611, the main difference being that they replaced the MXM slots with PCIe slots.

ZRTK-21612:

I added the Letine M08.

Let me know if I miss any other motherboard.

[mrb]

I added the OEM B250 12P where all 12 PCIe links are in the form of mechanical USB ports, in order to connect your riser cables directly to the motherboard.

[mrb]

I confirmed the manufacturer of K17/K37 is Yanyu Gongkong.

I added the Yanyu Gongkong K35, very similar to the K37, but with a Celeron and passive heatsink preinstalled.

[mrb]

There might be a 12 slot PCIe motherboard, but I can't find who manufactures it. This is seems to be a Shenzhen Zrt Co design. I contacted them to confirm... Only one random Alibaba seller has pictures of it: https://fashionplaza.en.alibaba.com/product/60680844122-805574575/Fast_shipping_p106_12pcs_gpu_ZEC_Zcash_ETH_miner_ethereum_mining_machine.html

However I have a sneaking suspicion of this being a scam, a picture photoshopped from ZRTD-101. Slots 4 5 6 (from the right) seem digitally inserted. It's a wide area with no screw holes for support (flimsy), and the PCB/component layout is too repetitive. And the entire rest of the PCB layout (even the faintly visible traces) are strictly identical to the ZRTD-101... Plus powering 12 cards with the 12 power outputs on the PCB, fed by only 7 power inputs is not a great idea, unless your cards are low power, but then it would limit the utility of the mobo...

[mrb]

This is turning into a quite handy reference.
Thanks

The lack of comments started to make me think few were interested 

[mrb]

Yanyu Gongkong drastically redesigned the K17 v1.0 into v1.2 which is now almost identical to the K37 except:

• K17 v1.2 has two mechanical USB ports carrying a PCIe signal and two 2×5-pin header carrying a PCIe signal.
• K37 has four mechanical USB ports carrying a PCIe signal and one 2×5-pin header carrying a PCIe signal.

I am waiting for confirmation from the vendor whether these PCIe signals are fully usable. This would technically make the K17 v1.2 a "12-slot" and K37 a "13-slot" motherboard.

this post is really useful thanks!!!

do you think that the  Inno3D could be a good choice for starting out mining altcoins as an hobby?

Of course not, others may silently reading this and actually useful at their end, giving you merits for this bro

Olike Board?
