holy mackeral!!! -- this is awesome - LOL

do they sell the mobo only?

try redo the sata and molex connections with dedicated cables - you should have 4 sata and 2 perifs on your ATX PSU

do you hear a beep upon power on?

Im at a lost with this D1800 board, i cant get it to post for the life of me, ive tried 2 different ram sticks, 5 different GPU's... just nothing... gonna file claim to get my money back, the seller has not responded to my messages in over a week.

that board is so long it reminds me of that "bitchin'fast3D 2000" video card joke:

lot to be said for this

just use 6x  1080 ti's

The mobo citronick has (9 pcie slot + compute card), there's a new, even longer mobo with 12 slots.

I got a 1080ti rig that now fails to post. Really troublesome, it doesn't even post with 1 gpu, and after swapping the motherboard.

Hope the issue is with PSU or mobo (again), and I don't happen to have 6 dead 1080tis lol. Can power surge kill cards?

Now awaiting a new 1600T2 psu to arrive on Amazon. I shouldn't have went with the unknown platimax 1700w psu in the first place, but every good psu was OOS 3 months back.


About the 12gpu onda server case: https://www.alibaba.com/product-detail/4u-6xgpu-8xgpu-12-gpu-cards_60709559773.html

I got a quote of $680 shipped to my farm. Comes to $56/gpu.

$620 shipped for 8gpu version.

You guys heard of localbitcoins.com ? Not sure you have it in the States. Used to be the only way to trade BTC directly against GBP here. Unfortunately now the market seems to be thinning as more exchanges appear (coinfloor for example) so these plonkers widen their market making spreads. 5.5% spread on GBP/BTC now it's surreal.

No vegas for me can't help.

But  btc = $8162.00   damn

hey, fellas

I just got the fourth Vega for an existing rig, it would be replacing rx 470 in the first 16X slot.
one of prior 470s to Vega replacements on risers was stubborn and required DDU-ing the blockchain driver, then re-installing it. Before doing this, Windows were reporting that the card was there, but driver (and GPU-z) did not see it at all, hence no mining.

Q: some people report that replacing 470/570 card in the first 16Xslot (the one that normally outputs to display) with Vega results in a blank screen. Just trying to optimize the procedure.

Does DDU-ing, than re-installing the blockchain driver works in this case (on mobo, not risers) as well? I would hate to connect Vega and than be forced to reconnect 470 back.

Thanks

It's solid enough I could put rollers on it - but no point at this time for me.
If you build one, a common "4 bolt" type castor should work by using wood screws into the bottom of the vertical 2x4 on each corner.

No need for a shroud either, it'll be positioned so that the intake side is in my "cold aisle" and the exhaust will be pushing back into the area my Evaps suck their air in from.

My planning right now is to rebuild existing rigs into 5-card riser rigs since my current motherboards pretty much all only have 5 slots anyway (the B250 Mining Pro being the one BIG exception, but that would end up taking up 3 slots for about a 15 card rig, mix of 1070 ti and 1080 ti cards if I did THAT - a thought I've already done a bit of "planning" for).

Tentatively, I figure long term on feeding one of these racks from a L6-30 drop cord with either a PDU or a self-wired subpanel setup with 4 x 15amp breakers (there is plenty of space to mount a small QO panel on the top shelf then route the wiring between 2 side verticals and mount the outlets on the shelf support boards).

Breakers 1 and 4 would feed 2 rigs each, breakers 2 and 3 one rig each (though I might go with a higher-power rig on those circuits) + 1 box fan + (monitor or LAN switch).
If I went with the B250 Pro option, MB and 5 cards would be on breaker 2 or 3, 2 "ps + 5 or 6 cards only" on breaker 1 or 4, and the MB would be running on at least a 1000 and possibly as high as a 1300 watt supply.

My current place doesn't have the infrastructure in place to do that (I only have 1 30-amp outlet in the whole place, and not planning to be here long enough to make it worthwhile to convince the landlord to let me rewire the place for more), but I can use 4 of these with the current infrastructure just by careful placement near existing outlets in the short term.

 A 6 card rig per slot would probably work, if you had a VERY low power CPU and MB setup - 1070 ti or 1070 should stay cool enough on 3.4" center-to-center riser spacing - but 5 cards at a little over 100 watts + existing FX 8350e CPU + existing AM3+ motherboard + existing ram/HD push right at 6 amps per rig which is the limit I'm willing to build a rig for when I plan to put 2 of them on a single 15 amp circuit - and I already HAVE several of the CPU/MB/RAM/HD sets on hand.

 One thing I have already noted - to get the full 24" width I need to use a fairly short card in the end position, like a Zotac Mini, or that card ends up sticking out past the back a ways for clearance - or I need to position the "rig" shelves back a little more to allow for more clearance between the "shelf mount" board of the slot above and the end of the shelf.
 Since I already HAVE some Zotacs (and some Gigabyte ITXs that are even shorter), that's a trivial-easy choice for now. 8-)

yeah  needs quality rollers  for  easy access

sure looks solid. add castors and just roll em to where you want em.

Phil   solar array video is nice

Early glimpse at my new project.
Been bouncing this design around in my head for a while, but decided to finally get off the dime and get one built.

 The new, LOW COST, Quintleo 6 rigs rack-shelf unit.

 (Ignore the date on the pics, I've not bothered resetting the clock in the camera.)

 When I build more than one, I plan to put sheetrock between each one to limit the potential of fire damage and to help direct airflow.

 The top shelf is offset forward, to put a keyboard trackball monitor and LAN switch on.

 The other 6 shelves are offset backwards, with the intent of mounting a pair of 20" box fans on the front to blow LOTS of cooling air through the "rig shelfs".


 This one I partly "recycled" one of my earlier shelf units to build.
 It also doesn't work out quite "even" on the parts - it needs one "spare" pair of the 16" cut boards for shelf supports.

 To build it, you need 4 standard 96" 2x4 boards (2 cut in half for the 4 verticals, 2 cut into 12 each 6" x 16" boards for shelf support) plus a spare 1/3d of a 2x4 for the shelf supports for the last shelf.
 7 x 2'x2' fibreboard (I prefer to stay close to 3/4" - can use plywood instead, I'm not sure if particleboard would be solid enough to work but PROBABLY).
 56 8-penny common nails (can use 10-penny in a pinch but the ends tend to stick out a bit past the end of the boards.
 70 6 penny nails (hold the shelves on AND provide rigidity left-to-right)

 I went with the "6 rigs" option mostly due to power distribution factors - it's entirely possible to build a varient that will hold 8, or 10 rigs without getting TOO high to be workable with.

  for me  I would go with the scythe  use the controller to drop them to   100cfm at 2200 rpm  and use a lower tdp.

I  think I will have spotswood build a case for the onda 8 card + 4

I will be looking to run 7 or 8 waterblock cards on the case.

 12038 is a SIZE description - 120 x 38 mm - which describes a TON of Delta high-CFM models.
I do agree that just the MIDDLE fans should be plenty for that case, dunno why they think they need a push-pull setup.

Delta AFB1212GHE soaks 3.24 amps at 12VDC (per the label on the back of the one I'm quoting from) - I think the "focused flow" fans soak a little more but not a lot, perhaps 4 amps for the GHE models.



 MFJ Enterprises is still alive? I thought they died years ago.
 Used to use some of their Ham Radio related stuff.

Hi, I see that there are some MoBo test on this thread. Onda D1800 BTC work fine with gtx 1060/1070 gpu or is better a Asrock H81 Pro BTC and pci risers.

Thanks in advance W_M
