Mining motherboard - Onda B250 BTC-D8P - Anyone tried ?

[dlezama]

Since I’m waiting for my warranty replacement for my octominer motherboard I went ahead and ordered a Onda B250-d8p-d3 which is the newer version with only 8 slots and none of the extra ports. It also has a completely different layout for the connections that will no longer interfere with your first card. I will testing it vs the octominer and will do a full review of both. I’m hoping this Onda will fit in my octominer case. They look like they are based off the same pcb so fingers crossed.

I have both, size is a little different, separation between cards is a little bigger on the Onda too.

yeah, id say the slot spacing on the onda is 2.2-2.25x the standard spacing.   There's enough room to fit an EVGA with its massive super over sized cooler and still have room to breathe between cards.

Does anyone know the nominal and max power (watts) that is drawn through each of the 3 molex ports and each of the 3 sata ports on the D8P if only slots 1-7 are occupied (slot 0 empty)?

Reason I'm asking is because I want to run 2 PSUs to this board and I'm trying to decide the best way to split power between the 2 PSUs (1800W and 1200W) with all 8 PCI-E slots occupied.

Are most of you guys using the original Onda board hat has the 12 gpu capability or the new one with just 8?

D8P, v1 (12 gpu).  rock solid. short gpu required for slot 1. only running gpus in slots 2-8 for now.

I do with a few and try to make sure each psu is powering the same card(s) through both molex/sata and vga, so if one psu goes down there is not a card being powered only through the pcie slot molex/sata--but this suggestion came to me when I jumped psus rather than add2psu connect, with risers where the sata adapter to the riser could melt if a different psu to a card went out and the card was trying to draw 120 through a cable rated for 75. In my experience wiht onda b250s if the sata/molex to the board is unplugged and the card powered, it's just not picked up, and vice versa.

Have guys found any closed/server style cases for the Onda boards?

Yep.

quick google searches my friend.....

 I’ve seen that one, I asked in case someone had come across anything different. /salute

I have the spots wood for the eight + four board

I consider getting a second one

[ManeBjorn]

I have one of the Spotswood cases on the way should be here next week. Going to be fun.

Hello, I have a problem with ONDA B250-D8P

i have all plug :

- Intel Celeron G3930
- sodimm 4 GB 1333 MHz 1.35 V RAM
- all connected connectors molex ...


Start bouton and :

black screen nothing hdmi video output signal on my screen. Can not access bios. However usb lights and keyboard off.

how to treat hdmi display activation with no bios acces ?

any other GPUs connected?

Do  you have both the 24-pin power cable and the 8-cpu power cable connected?

[bubbAJoe]

hello bubbAJoe thanks for help

24 and 8 yes   and all connectors

i don't have gpu card on motherboard just use hdmi from the motherboard possibility.

- cpu is Intel Celeron G3930
- ram is sodimm 4 GB 1333 MHz 1.35 V RAM
- all connected connectors molex ...

DDR4, I assume?

Dunno, I'm running 1.2V DDR4 on both of my boards.  Does this board require 1.2V memory?

Also, double check CPU and memory seating.  Check memory contacts for any tape/glue.

This main board is really stable so far. I have an i5 CPU and this for ram.

I really like the Spotswood frame too. Easy to setup and works great.

my cpu is new. how is the good frequency memory ram for this motherboard? 1.2 v or 1.35 v ?? what the people use ??

For a short test, Ill be using one of these as a mining and gaming machine at the same time........  Just to see how well it can handle it.

My mSATA and cpu cooler arrived today, so finally time to populate and power this puppy up.

good  so win 10  with the i3 I sold you   if I recall .

 what size ram?

[ManeBjorn]

I messed around running games on an 8 GPU rig last summer. It was fun but it seemed like the games could not even close to use all the power of all the cards.
Have fun, I look forward to your results.

My 2 ONDA D8P boards are running rock solid. I have no complaints.

I just wish I understood how much power was sucked through the 3 SATA connectors and the 3 molex connectors on the board for the purpose of dividing PSU power in a multi-PSU set up.
