Review of Panda Miner coming up.

[citronick]

@Phil - Is this Panda completely just powered by PCI only?  This would be fantastic news, as I can power a ton of this without needing ATX Power supplies.  The IBM 4KW Server PSU bundle seems like a winner's choice for this.  . 

yes the Panda need only PCI-E 6 Pin nothing else.

How many PCI-E sockets in total please?

What is the difference between a normal PC motherboard compared to this Panda "PCI switch" based motherboard?

it uses moblie   cpu

it uses 1 ram slot

it fills gpus on both sides.

a 24 inch wide  rack  with four shelves  can do  12 units


                    4k psu
               pandaminer
               pandaminer
               pandaminer

each shelf  would load as above


now  if xmr holds price and the linux build  works well  you could run 4 units per 4k psu   and here is why

this unit below rates at 2320 watts  2 of these would give 4640 watts

using the 4k breakout board from optimizer  not j4bberwock/finksy

use the 5th shelf for your pdu's

two 30 amp pdus on the fifth shelf

and this rack has 96 gpus running

WOW --- my entire warehouse can be replaced with only a couple of these racks!

Now that's efficiency and perfect for lights-out operations because it will impact and saves cooling and electrical cabling cost.

And.... best of all.... I can throw away all those darn PCI-USB risers!

Yeah this is what peaked my interest when they started talking about these.

The only issue for me is I need that density to fit inside an enclosed rack. Don't have option of using shelves as described, wish I had more room at home.

yes  only 1 slot up to 8gb as tested by me  it came with 4gb  I put this samsung ram in it


https://www.amazon.com/gp/product/B00J8U549K/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

it comes with a mobile cpu


http://ark.intel.com/products/84810/Intel-Celeron-Processor-3215U-2M-Cache-1_70-GHz


I would have liked a better cpu as mobile cpus are harder to source.

but this psu an i5  is 281 list

 http://ark.intel.com/products/85212/Intel-Core-i5-5200U-Processor-3M-Cache-up-to-2_70-GHz


and the one that comes with it is 107 list.

Are you able to use the MSI afterburner to change the voltage or frequency? I think the power consumption is pretty high.

the linux build which I don't have access to can save more power.

as of now  the oem windows build has limits and I am more gear orientated then software skilled.

So I am  taking my time  until I make a backup copy.

Since it uses the old master I had to order a 64gb  which arrives on thur.  which I have 2 mSata suds that  work I will be more aggressive.

can you show me a 6 gpu rx 480 doing   1290h  and 780 watts

this is a 8 gpu rx 480 doing 1720 h and 1060 watts  at zcash

running in a 93f garage



As for eth  it was doing 237mh at 1170 watts ran for 6 hours in a 95f garage then crashed. 
So for now I am mining zec  as I am saving watts.

[xxcsu]

Nice piece of hardware for sure , but the price is too high.
Price with psu and Shipping to the US is over 2400$

I prefer to build my own rig till they price is not going to lower with a few hundred $

7 gpu build :
7x Rx480/4gb mem  7x190$ = 1330$
ASRock H81 PRO BTC R2.0    =65$
celeron 1150 cpu                  =45$
4gb ddr3 (4x4set 42$)          =10$

120gb ssd                            =45$
                                TOTAL 1952$   1832$ (server PSU with breakout board)
using server PSU with breakout board can save you around 120$
free shipping on all items within US

build with RX480/8GB and 8GB system mem : 2302$   /  2182$ (server PSU with breakout board)

The only issue for me is I need that density to fit inside an enclosed rack. Don't have option of using shelves as described, wish I had more room at home.

that's good feedback for Pandaminer, i.e.: make the enclosure so it fits in a standard 42U rack, and include mounting tabs.
https://en.wikipedia.org/wiki/Rack_unit

In the meantime could you put shelves in the enclosed rack and put the miner in so the 20" dimension is front to back? Yeah, the fans wouldn't be facing in optimal directions, but it might work.

not sure they can do that make a 18-19 inch rack mountable unit due to with or length of mobo.

the wire shelf systems  with 24 inch wide 14 inch deep 72 inch tall look perfect.

I would have like a better cpu  and maybe linux instead of a patch windows 10 still all in all really nice piece of gear.

Todays' price is 2180  + shipping and that includes a psu

with BTC rising  this a pretty good price.

agreed, they would need to change the exterior width dimension of the case by ~21mm from 503.5mm to 482.6mm to get it to fit, and judging from the pictures the mobo is already a tight fit.

yep, looks that way.

It would be an interesting engineering exercise to see how many GPUs they could fit in a standard 2U full depth (87.3mm high x 445.5mm wide x 730.2 mm deep) enclosure. This would fit in a standard datacenter rack (dimensions taken from an HP DL380G9 without a bezel).

This would work yes but it would exhaust hot air into the rack which would likely get circulated back into the miner and heat it up more without fans in the top of the rack which I don't have unfortunately. If I had fans in the rack at the top it would work though. I have a standard cold intake front, hot exhaust back setup.

When you have racks it's better to have same space in front and behind to make air circulate properly, so if they do a case with screw mounts for bracket on each side (front & back) you could actually mount 2 of them in a 2U space (one in the front one in the back) and turn the fan toward the air flow, then you would probably for airflow too, use the space in between 2 panda miners to put the 4x PSU's then again 2 panda miners. As for completing air flow, probably want also top exhaust too to make triple air column.

here is a crude mockup of what your rack could look front & back. (full 48U rack) 2 possible setups for maximum air flow. First setup could more efficient, you would use the space behind the PSU's to put all the PSU & network cables. In thoses setup you could fit in one rack about ~26-28 pandaminers.

You could probably save up even more space by using server PSU's that are more long and flat, and have the fan usually in the back but would probably be more pricey. But that's the idea

it is not about the case.  the mobo  is a perfect fit in the case

left side                 ___________________________ right side
 has 2 usb                                                                has 7 pcie jacks
2 hdmi
1 ethernet
1 power button       ___________________________


all jacks are soldered to mobo and fit the case perfectly very good quality fit and finish

to shrink to fit a 19 inch rack   you need a 6 card mobo

now a six card mobo  could be much  less width  say  16 inches
make the unit tall make the heat sinks taller
and you could have 92mm fans but that is a completely different model and idea.  I am not sure it is any good.

the wire shelf can be modded with walls on the sides and small holes for the wires

you could even make the wire shelf sides 24 or 30 inches


that would allow for more fans to attach to the shelving for better air flow in the building.

BTW  picture a sliding door   with a rack pointed at it .

a home could mine 96 gpus easy

72 by 24 by 14 wire rack

 at least 10 possibly 12, using the WX series stuff and a standard EATX server motherboarda - I'm sure there's a MB out there somewhere (probably SuperMicro) that will fit into a standard 2U with 10+ PCI-E slots.

 Might have to use the WX 4100 though, as it's the only low-profile card in that line.

 You'd run into the driver limits on how many cards you can run first, unless you do one of the mods that allow for more than 7 (like they already did).

 On a custom MB like the Pandaminer uses, they'd probably be able to do a fairly easy redesign, go with more depth and less width and change the connections to front or back.

 Not sure if they could squeeze the vertical down the half inch needed to get to 3.5" (2u) height though without some serious airflow compromise. How much free space is above and below the heatsinks in the existing case?

 They COULD go deeper and then go one card high 2 deep, but that would definitely impact cooling on the rear cards.


 92mm fans WILL NOT FIT in a 2u case - there's only a total of 89mm (appx) to work with NOT counting the thickness of the care top and bottom.
