Colorful Intros a Non-standard Motherboard with Eight PCIe x16 Slots
Colorful today introduced an non-standard form-factor socket LGA1151 motherboard for crypto-currency mining builds, the C.B250A-BTC PLUS V20. This board is 485 mm in length, and 195 mm in width, and probably won't fit in even HPTX cases for its intended use, but is suited for custom rack-type setups. It only includes the most bare-essential features to set up a mining rig with up to eight graphics cards, with 2-slot spacing between each card. The board lacks a 24-pin power input, so you can share your high-wattage PSU with multiple machines based on this board.
It features two 4-pin ATX power inputs for the CPU, and sixteen PCIe power inputs, of which eight can be populated at any given time to supply power to the PCIe slots, optionally all sixteen can be plugged in. The topmost x16 slot is gen 3.0 x16, and wired to the CPU, the remaining seven are gen 3.0 x1, and wired to the Intel B250 Express PCH. The CPU is wired to just one DDR4 SO-DIMM slot, since system memory isn't that big a bottleneck with GPU mining. The board's connectivity, too, is bare-essential, with just a couple of USB ports, an HDMI display output, and a single 1 GbE network connection. The company didn't reveal pricing.

If yes dosent make it better :confused:
but i think i like it.. he he..
trog
- Get into AI research
- you can fold with those for the good of humanity
- Cracking passwords!
- Warming up the basement/garage/tool shed
- Utilizing unused CPU/RAM/storage power to run NAS, do Excel spreadsheets, or draw ugly pictures in Paint3D.
It helps a lot to save time and possibly money to build the missing parts around those, x1 cramped together, boards.
There are enough pictures from mining farms using similar designs like that board.
Those are mostly without cpu socket, what makes it possible usable for me.
And besides crypto, the other mentioned enough use cases.
e.g. an alternative for the 2K$ upwards Nvidia KI Ubuntu Tower.
If you are interested:
Those Boards with a bunch of x1 sticked together are mostly derivations of the cheapest Designs.
I only have in use a H81 PRO BTC and R2.0 but I'v checked most of the Boards in reality.
- PCBs bend in all directions as the layers for stability are missing or the wrong materials,
- they have to mention the feature that the power rails on the PCB have enough copper to power the connectors, if you need them be shure that they mention it.
- you need the extender Boards, where if you need quality you have to add each 7$ and above.
- you have to get the routing correct fot the x1 the get even GEN2 speed , if you e.g. cross Power lines or have to much bending on the cheap USB3(3.1) cables you can be happy to get GEN1 working.
etc.
I do not do any crypto mining, but I really would love such a "no bullshit" Mainboard for my PC builds.
I don't want:
-crappy Realtek NIC,
-crappy Realtek Sound
-childish RGB lighting
-additional cheap SATA controllers
-any other bullshit, that costs money and has no use
So actually I'm paying for a lot of stuff that I don't use with every mainboard.
I just want a CPU Socket, DIMM slots, the chipsets' own SATA ports, some adjustable fan control and as many PCIe slots, as the chipset can give me. (maybe like one 16x, two 8x, two 4x and two 1x) So that I can put in quality gpu, nic and soundcards of my own choosing. And reuse those components when I switch to another motherboard...
I mostly meant the "no nonsense" approach is what I'm looking for.
Also the ridiculous number of power plugs. 2x8pin for each PCIe XD I just wonder how you daisy chain PSU's to work, there is no way any PSU has so many PCIe power connectors. But you need to synchronously fire them up, you can't just run them afterwards...
Still, two slot spacing is pretty tight for cooling 8 full length cads unless they are blower cards. Maybe alternate full size and ITX sized cards.
But I like the simplicity of non riser rigs that are more or less self contained, zip tied fans kinda ruin that. But gotta do what you gotta do to keep it cool.
EDIT I also like the fact it doesn't use the 24 pin at connector making it ideal for use with server psus.
They should of included a power on/off switch.
It's not that bad or stupid, it's simply not mainstream. Same thing can be used for "DGX-1 on the budget" or "Project 47 for really broke", which will make at least a few researchers and scientists happy.
