Well it depends on the cost, currently my expense for mobo+cpu+ram+ssd+psu+risers+rig comes to around €25 per pcie slot with easily available hardware. If these boards can make an improvement on that, sure why not.

Add me to those who have not had a riser issue. Granted I only use seven, but they are from two different kits of six, different brands, different styles, and they all work perfectly.

love my onda b250 d8p v1. will never build a riser rig again.
some of those riserless boards have better slot spacing than others, the d8p v1 is very good with 2.5 spacing. i dunno how well a 2.0 spacing board will do cooling wise.
but the d8p with its 2.5 spacing will not fit in a server case whereas a board with 2.0 spacing would.
one thing i will always want in a riserless board is a socket for the cpu rather than a built in. just personal preference.

Yep, I have been adding cards to my 2nd Onda D1800 6-GPU mobo as I get them in and I really like these boards, BUT....
The 5cm PCIe slot spacing on my D1800's is just too close to allow the GPU fans to pull in enough air, and I am not running terribly powerful cards in either rig. One D1800 is kitted out with RX 560s and they aren't such a problem - only 75W max TDP and a bit thinner, too - but the other one is loaded up with GTX 1060s and it has been a real struggle to keep the first 5 cards cool (the last one is fine since its fan is unobstructed).
The Celeron CPU is also woefully underpowered - you pretty much have to stop mining if you need to interact with it at all. I'm not saying it needs an i5 or a Ryzen or anything, but even something about 2x faster would be a tremendous improvement. That said, the wimpy CPU is a main reason why the mobo only needs about 30W...

Can you please post some temperature data on those Zotac 1070 ti mini's? How did the 8 of them do in the case over a period of time?

Question: can these boards operate with spaces empty? say with 4 cards? Different versions of 580's ok?
Would think so but I haven't seen it covered yet. Thanks!
yes that is no issue / can skip slots and use different cards Would think so but I haven't seen it covered yet. Thanks!

I've been running an Onda D1800 6-GPU mobo for over a week continuously now mining ZEN. It's an all GTX 1060 setup (don't laugh - it's all I could find that wasn't priced so high it should've come with a bottle of anal lube) so not the highest power but keeping it cool has been a challenge. Right now I have a box fan suspended above and behind it to keep temps below 70C - and note that total power draw at the wall for this rig is 700W (300W to the mobo and 400W to the GPU PCIe power inlets).
The Untel Celery® CPU is slow as Christmas but gets the job done as long as you don't interact with the desktop too much. It's been very stable with no crashes or strange GPU nonsense once I got the O/C dialed in for each card (4 are the same and 2 are both different). The built-in VGA port on mine works (v2.00) and though it made initial setup a challenge (lol, VGA), I was able to scrounge up an old LCD monitor from a local computer recycling outfit.
Overall I am very pleased with the performance and if the PCIe slot spacing were just increased from 5cm to 6cm I think this would be a real winner.

If I remember right, I noticed the reason was a loose Molex connector wires connection to the riser board, bad soldering work.

Riserless mobo's?
USB Risers?
Nah, my rigs are still using the ribbon risers. 2013-2014 mining FTW

Damn those ribbon risers were dangerous for me back in the 2014, I still remember one suddenly bursting in to burning and lots of smoke because of that.
Nothing else than the riser was damaged, luckily. Maybe I just ended up with a bad quality batch one, but I would be careful using those.
Its probably because you didn't cut the +12V line going into the motherboard.
Some suppliers cut this for you... some lazy ones didn't.
So what happened was you were feeding +12V from Molex and a parallel +12V was supplied by the motherboard. Since the voltages were exactly +12V, some current feedback loop was created and BOOM!

I did forget to mention a big thank you to Phil because without his suggestion I would never be using Hybrid Coolers, so thanks Phil! You are the man!

Looks like good but space between GPU very low, With risers i can buld more effience rig.
With this mobo need to delete stock cooling system and create side winding system

These boards are great with Evga hybrid 1080 ti
The pre loaded waterblocks do 700+ and run cool
I have four six card 1080ti rigs each do 4200 sols.
Riser rigs are meh compared to these rigs.

I do agree with you that the Hybrid 1080 Ti's are AWESOME - I'm up to 25 now, mix of EVGA and the Corsairs but they are awesome. I'm really seriously thinking about buying the hybrid kits for the rest of the cards since I maxed out power and grid won't handle an AC but I'd have to spend another $22k for all the upgrade EVGA kits.
So I'm now thinking about testing maybe an EKWB waterblock but not sure. We shall see.

I buy the mobos along with the server cases. With 4x 3700rpm fans, even 1080tis are kept below 70 degrees at 77% PL. Both blower and dual fans one work well. (Except for Inno3d twinx2 which has a terrible cooling solution)

Dual mining for 8+ months on USB risers and zero issues as well. For mining, risers are advancement from having to cram multiple GPU's on to a motherboard. These boards are a step backwards IMO, unless you plan to cram them in to a server rack.

Tough call because I've had absolutely ZERO issues with risers, besides a dead one here and there but I always order twice as many as I need and refund the rest so it never matters.
