anyone have experience with the riserless Biostar Mining Board TB250-BTC D+

https://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=902#overview

will they run 7 x 5700 im total noob to all this and hesitant to buy and cards wont run on it. have a asus B250(19GPU) motherboard that's slowly driving me insane.

Mate the link you dropped isn't working, you should try fix that first and I don't advice running RX5700 cards next to each other without proper space and ventilation simply because these cards gets hot easily unless you are from snowy or cold areas like Chicago or so, risers are a must to keep the cards alive for years to come. Heats are the worst enemy of graphics cards

The problem with this type of motherboard is, it can not give the gpu a proper ventilation and also the cards place in a area that wont circulate and get the better airflow each cards, in the long run the oberheat problem will occur in this type of motherboard, the space is more important in gpu mining because it will produce excessive heat and it will give a high temp in all of the gpu.

Look if you alternate cards they work great.

no temp issues below and fans are not high at all

hi John, thanks for your comment. yes, i believe running more than 4 gpu/per board will have issues. quite happy to run 4gpu per Mboard, picking these(motherboards)up at very good price. as soon as they in hand will update this thread on assembly

Let me know how those GPU's fit. I remember reading somewhere those motherboards had very little space between pci slots.

he is doing every other slot only four so they will fit well.

I checked all my boards and my three biostars are up in clifton nj about 65 miles from my house.

so far they are very stable.

i use g4400t cpus. one of the lowest power cpus for these boards.

wow..been seeing your posts for a long time. BTCtalk lucky in having such helpful members. thank you kindly sir. haven't purchased the biostar MB's yet but will update this thread with pics of my current gear already in hand in couple hrs...i do have apw3 and 7's along with 2 of these(full cable kit included)

Nice they should have two full sets of eight pin each.

or 4 cables. which you could use 1 of the four and make two good four pin cables.

hook up one of these antec psu’s and test the four pin with a meter.

You then know what pins are negative and postive.

you also know the board works.

Do you know how to start an atx with the jumper to the 24 pin cable.

thanks Phil, im planning on running 4 cards per Mboard(these rogs are thick and big) want to avoid any heat issues with cards stacked to close to each other. ill post pics of gear in the morning(im on south african time lol)

don't cut your hands when you cut the solid eight pin.

I used a big sharp knife for photos

but this tool Is better

can you link me your Asus gpu's so I can figure best adapter for them?

https://www.evetech.co.za/asus-rog-strix-rx-5700-oc-8gb-gddr6-graphics-card/best-deal/6906.aspx

okay 8 pin + 6 pin

do 4 per board.

https://www.amazon.com/Graphics-Express-Splitter-Power-Extension/dp/B073M4643C/ref=sr_1_21?

these will work 1 direct from apw3+ to splitter above to one gpu

that takes 4 cables of the apw3+

you have six cables left from the apw3+

put all six into the inputs of the mobo

as long as you run the gpus at 125 watts or so the cables and board will hold.

these are stats from 1 rig using an apw3+

this is a rig doing 181mh and about 570 watts at the wall. it is very stable.

your rig should do closer to 200mh and maybe 630 watts at the wall

These were nice boards they sold out fast I only got 3 used ones.

but the apw3+ psus were on hand and free.

I had a lot of spare cpu power cables. Test test test once you build them as you want correct polarity

I had spare cpus
I had spare ram
I had spare wire adapters.

I only needed 12 cards well actually I think I did 5 on one of them so 13 cards.

Nice good info. Can you skip powering the GPUS from the board and go straight to the PSU?

yes. you can go right to the gpu but you still need to go to the board since the risers need power.

you need 5 from an apw3+ psu to go to board

that will power the riser slots in the board.

you need to use the cable you just built. it plugs in next to the input risers on the board.

you can then use the 5 remaining apw3+ cables right into your gpus.

if you do the right gpus

these will adapt the six pin apw3 six pin

I like to use this gpu on those boards.

'The right to privacy matters'

the 8 pin cut side may have some pin/jack metal exposed use some black tape. it is safe as you are not pushing the shit out of the cpu.

test cable to be sure it is proper

so you can make 2 from this one.

with some electrical tape.
and a razor sharp knife

'The right to privacy matters'

a standard 8 pin cpu cable

pulled into two ends of 4 pins and the solid 8 pin

cut the solid 8 pin end with a razor or a sharp knife

depending on the psu cable once cut you could be tangled

I cut one wire makes one whole cable and one cable you need to splice

Sorry for delay I got stuck for a while.

The shots below are not of your board but I have 3 of yours have to find shots.

here is how to fit 5 cards.

on 8 slot boards. if you see just make card 4 be over sized. and card 5 be undersized

https://i.imgur.com/TwpdOAE.jpg

This board is not your board. Still looking for photos on your board.

the board below is a six slot with 4 cards.

I ordered four used on ebay. Three were good one had a few bent pins.
You can run five cards easy peasy.

Bitmain psus will run it.

When I get home I will show you how to wire it.

You do not need a ton of cables if you use fivecards.per board.

Give me an hour or two I will post photos.

that's awesome, huge thank you!
