Moderately hopeful rendertoken or other forms of gpu marketplace gains traction this year.
Where are rendertoken currently at? Beta-testing still? Not currently giving out live rendering jobs yet are they?

...

EDIT: not considering ASICs at all. Not out of snobism, but because they really make no sense currently unless you're in need of a big door-stopper.

Their roadmap: https://rendertoken.com/#roadmap
With any luck we will be rendering by end of the year.

I'm not a huge fan of ASICs too, but I will still grab some ASICs in promising algorithms to diversify, mainly those with good revenue to electricity cost ratio.

I'm keeping an eye on them too. I really hope that blockchain rendering takes off since I think it's an excellent use of "traditional" GPUs and may prove to be a safeguard against Asics (I think).

probably have to rebuild most miner rigs to render. with a lot of rigs having 1 pcie lane per card, 4 gigs ram, undernourished cpus and little storage (120 gig ssd or 32 gig flash drives..  well i cant see how its going to be able to get all the textures and such to the cards in enough time to be useful.

maybe rigs with 4 cards at pcie x4 or 3 cards at pcie x8 along with a good quad+ core cpu with much more ram, 16+ gigs maybe. and storage for jobs so 512 gigs or more. <-- all specs guesswork on my part

wonder how much bandwidth it needs?

Here's an extremely detailed 3hr long discussion on setting up an octane render rig. At 1hr 37 mins they talked about pcie lanes: https://youtu.be/XrOBvz454fU?t=1h37m40s

TLDR: A 8x pcie 3.0 connection per gpu is highly recommended

Long version: Pcie 1x lane works too, and the rendering speed is unrelated to lane bandwidth. However during data transfer the rig will be idle, which happens when you are receiving new job or swapping out the textures in gpu vram. The penalty will be especially heavy for out of core rendering (Scene is 64gb, gpu only has 11gb, there will be loads of transfer from system ram to vram).


When beta testnet launch, we will get a clearer picture on the ideal rig setup. Risers MIGHT still be the best price performance because a Threadripper mobo + 1900x will run $700+ USD and only fits 4 gpu. A gigabyte B250 fintech with 12 gpu and 64gb ram might be better bang for buck.

On a side note the Gigabyte b250 fintech is the only mining mobo with 4x ram slots, and 64gb imo is a must for rendertoken.

I hope someone comes up with a Onda B250 form factor threadripper board, with 7x pcie 8x slots and 2x m2 pcie slots. To run 7x 1180/2080 + 2x acorn fpga accelerator.

so I have a ryzen 1800x  on a board that can do three cards and I have 64gb ram and I have a 2tb ssd

so I guess it would work well to render.

I have this board  https://www.newegg.com/Product/Product.aspx?Item=N82E16813157757

I have this cpu  https://www.newegg.com/Product/Product.aspx?Item=19-113-499

I have this ssd  https://www.newegg.com/Product/Product.aspx?Item=9SIA8TK78R3886

I have this ram https://www.newegg.com/Product/Product.aspx?Item=N82E16820156086

I have 3 of these gpu's  https://www.newegg.com/Product/Product.aspx?Item=N82E16814487346

So this should be good to render.

it is fully paid off.  So roi is not an issue.
yeah a custom board with 4 ram slots and 4 gpu slots
would be good , i hate risers

I'm considering taking the motherboard in my personal desktop/workstation, an Asrock Fatal1ty X370 - https://www.asrock.com/mb/AMD/Fatal1ty%20X370%20Professional%20Gaming/index.asp - and making it a test bed mining or rendering rig. I think should be good for 3x GPUs with an Acorn mini accelerator and it's current CPU a Ryzen 1700X should be more then up to the task.  Does anyone have any idea if rendering requires faster RAM, or will the cheapest DDR4 2400 work just as well?

Cheapest ddr4 will work.

There aren't much cheap 4 gpu slot mobos that still provides the pcie lanes.. Cheapest combo Ive seen is this asrock C612 mobo: http://www.asrockrack.com/general/productdetail.asp?Model=EPC612D8#Specifications

Coupled with a 4C8T Xeon 1620V4 40 lane cpu, it will provide all 4 gpus with 8 lane each, and still has a m2 pcie slot for acorn. This combo will be around $600 USD while a threadripper 1900x mobo + cpu is just $700 USD.


This epyc board will work with 7 gpu, but you need 16x risers: https://www.anandtech.com/show/12985/asrock-rack-goes-amd-epycd8-workstation-motherboard
Has 2x m2 pcie slots for 2 acorns. Probably cost $600 USD +

that asrock board using the xeon  allows for 8 sticks of ram
