the only thing stopping me from pulling the trigger on one of these is the MXM video cards, i am still trying to figure out upgradability :/
cause tbh, with how GPU's work, it will be no different than any other miner, it will NEED to upgrade to stay viable.
i would HATE to buy one of these, then VEGA drops and the possibilities open up. IF its easier to upgrade my own GPUS, ill stay with my own rigs


these are not for people who intend to upgrade them within less than a year - not sure what you expect to do with the used rx480 cards even if you did do the upgrade?



right, so why would these be appeasable ? just the plug and play thing?


hmm, interesting...

@Phil. so are you looking at about 12 months+ ROI at 3k purchase price? IF not upgradable, that doesn't sound promising :/

My understanding is - you cannot easily upgrade MXM GPUs. Only source of them for customers will be on Ebay from users cannibalized their laptops.

I would gladly be wrong on it

thats what i was thinking, so i just dont see the reason to buy one of these myself then, except ya the plug and play thing, but wont it just be a paper weight by (if not b4) one even ROI's?
AMD has new cards coming, so does Nvidia, as always.  Maybe Pandaminer will have local distributors one can take their machine to for upgraded cards in the future, as the ONLY thing that matters to me mainly is upgradability of these. the rest is just meh, can do it myself for cheaper (and more fun).



This system has a handful of advantages over a custom mining rig with fullsize gpus:
1) its pretty much plug-n-play, whereas a custom rig can take a several hours longer to assemble, install OS/drivers, etc even when done en masse
2) higher power density. you can stack these in a tight space (like a datacenter)
3) fans should last a long time, and are otherwise replaceable (80mm server fans i assume?)

This system isnt really for home mining. its for those who want to install a large number of GPUs where power is cheap and openrigs are not accepted (or require too much maintenance).

theres no reason why the rx480 wont remain relevant to mining (even if better cards are released) for at least 2 years. look at the fact that the 2xx series and 79xx series have both been profitable on ethereum and/or zcash over the past few months. even if the mxm cards can be upgraded, its likely most buyers wont be buying upgrades for it until 2019 or beyond (the case/mobo/cpu is only a small part of the overall unit price anyways)

MXM cards dont resell easily i imagine - so by upgrading youd be putting your rx480 cards aside to gather dust. As mentioned, i have 3 270x cards that are still turning about $0.30/day/gpu profit. I bought them in ~2014 for the litecoin boom, so its been over two years and they are still relevant

That said, i dont see why pandaminer wouldnt be able to obtain and sell upgrade boards to its customers eventually. I bet they can get the MXM cards at a good price (should be cheaper than a full GPU), tack on a bit of profit, and still sell them for cheaper than a fullsize GPU in stores.

If pandaminer plays their card correctly  they will take over a big piece of the gpu market.
This is why I tried to help them out .

This will get support on many levels.
First off the fans are fully replaceable.
The cards are fully replaceable.
This is a pc plain and simple.

Yeah they need a better os.  Maybe they do linux.
The linux build + roms by Eliovp is really good.

AMD  would stand to sell a shit ton of mxm cards .

And I know that this does not need to be noisy.  you can reduce fan speed from 100% to 50%

Here are the weak points  2 usb jacks ------- easy to fix just plug in a small  usb hub.
Fans  are loud --------------------------------- easy to fix with correct os. I am doing some fan work today.
Power on button is small ---------------------- easy to do an end around with correct os.
OS is an unactivated windows 10 enterprise -  can be fixed with a linux os
uses a mobile cpu -----------------------------  we could be offered a choice of mobile cpus from them
uses a single stick of ram ----------------------  as tested by me you can switch from 4gb to 8gb I do not know of any gpu mining that needs more then 8gb

Strong points.
 it is 40% the size of  two 4 card rigs.
the case is well built
is sound is not an issue  the fans  will keep it cool.
can be headless


a home miner can run these.
six of these   would fit on the rack below
so 24 full size gpus
would become 48 mxm gpus in the same space

one other (possible?) weak point; undernourished cpu.

some versions of claymore came close to needing more cpu than my G1840 could provide at higher -i values, and i have only a 4 card rig with that cpu.

wonder if future miner software would need more cpu, at least to reach max hash per card?

is that cpu replaceable? and if it is i wonder what the power delivery for that custom mobo is capable of. need low power cpus of course but still there are stronger ones.

i do like that thing, if my power were cheaper i would snag one, as it is my profit barely will allow roi, and the main reason i mine, aside from the hobby/fun aspect, is to offset the card cost and reuse the cards in future builds.

ah well. i have lots of yard (13 acres) so a solar array is in the plan in a few years. ground mount, single axis tracking. soon as the houses geothermal hvac is paid off  (3 more years) thats the next project.

moar power!

i wonder. mayhaps mxm gpus would have a higher resell value percentage wise compared to full desktop gpus? smaller market but then again not many for sale.

of course most would probably just buy a whole new laptop. dunno.

they fit in  some imacs  you  could sell them as an imac upgrade maybe maybe not.



the cpu is accessible.  and there are better models

comes with this list is 107

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

this is better but list is 281
http://ark.intel.com/products/84699/Intel-Core-i3-5020U-Processor-3M-Cache-2_20-GHz

this one would be really nice but it is  also281

IMHO, this Panda for me is the closest example of a black-box GPU "ASIC" miner, just like Antminers, A4, L3, Baikal or Pinidea X11 ASICs.... while these ASIC miners are enclosed-fixed-format and not upgradable, the Panda is unique and has good path for upgrades ~ RAM, msata and MXMs. The CPU is unlikely upgradable but enough juice for mining.

It ran nicely on W10-Ent with 4GB RAM out of the box. Linux with 4GB RAM is way more than enough. So OS wise, the Panda is covered. Like what Philip said, we just need some smart OS and mining SW wrapper around the HW.

I recall Eliovp (who is working on the custom Linux OS for Pandas) posting about his contacts getting information from AMD that MXM format will be around for at least 3-5 years, including the Vega chipset.... so it will be super upgrade-path for Pandas to have a second life with Vega MXM upgrade in the future.

Disclaimer: I have invested in a Panda and its running Linux currently mining XMR headless, very good temps, over 6k hash.

It was repeated several times that this miner is not for home mining. Is it due to noise? I have 6x RX 480 rig in room close to TV and have no problem with noise. I have a 4x RX 480 rig in my bedroom - and have no issue with noise.

Is PandaMiner really bad on it and cannot be placed inside the house (close to living room)?

Home mining, ie. basement is okay.

But put this next to the TV.... no way.

The stock fans are very strong.

Its like an 30% fan noise of a S9.... I think Philip did a db meter test.

it is louder then a normal rx 480 build.

the pitch is decent  but it is close to 70db.  the s9 is nasty and louder.

I know I can lower the fans I just have not bothered to as of yet.

No idea how loud S9 is and little idea how bad 70dB. But it is clear that it is louder than my RX 480 rig.

Phil how do you think one can reduce the noise?


UPD

I installed app on my Samsung S7 Edge to measure dB. 6x cards one is 47dB. So 70dB is LOUD!

Well I finally got into the bios and set the machine to boot on power up.

Or boot after a power failure.

My mistake of getting into bios was tapping. The delete key rapid fire vs just keeping it pressed.
So once I got into bios I was able to change just 1 setting.  The boot on power up. Allows me to fully avoid the tiny little power button.

I had read on threads this setting was possible and that getting the bios was possible.

I have exchanged emails with Zooey from pandaminer and they may develop more varied os. With English .

As for fan controls. The marketplace seller on newegg has not shipped my gear.  I can not tell you how annoying that a seller in Dayton NJ LESS THEN 50 miles from me does not ship timely. As I am almost certain his product would fix the fan issue for me.

My gpu heat sinks are not hot at all in the pandaminer. So I know I could drop fan speed a lot.

And here I am waiting for 12 freaking dollars of parts.

I have a really good control option.  I needed 3 pin fan cables.

I ordered more fan cables from a different seller.

give me a few minutes to post the controller

this does 100 watts

https://www.amazon.com/DROK-Voltage-Regulator-Converter-1-2-36V/dp/B00C4QVTNU/ref=sr_1_3?


I ordered these today..    from another seller

https://www.amazon.com/gp/product/B01CDKSV3C/ref=oh_aui_detailpage_o00_s00?


mobo --  3 pin wire ---- controller ----  3 pin wire ---- fans      for the back 4 fans

mobo---  3 pin wire ---- controller ----  3 pin wire ---- fans    for the front 5  fans



or 

this power supply


http://www.trcelectronics.com/View/Mean-Well/HLG-240H-12A.shtml  ------- controller ----- 3 pin wire ----- fans


I have every part but the 3 pin wire

Since my gpu's  are not hot  I know I can drop fans  to 11 volts  maybe 10 volts

would be  manual.

  this is a home miner fix  for the pandaminer.

I believe  that  the linux  from eliovp  has a better fix.

I am still playing in the bios  to see what else I can do .

I spell well don't I Grin

here is a photo or two
see controller it measures 8.47 volts  note the two probes.

To the left is a box, it has a pot with a screw.  volts in are 13.18  I can drop to 5 volts via the pot


now it is 8.22 volts



i am using an external brick on the left  it is 91% eff.  the controller is 97% eff.   I do not know  if the mobo will say fuck you  if you leave the two 3 pin headers empty.  which is why I ordered enough cables to test this with the brick and with the headers

It is not easy replace mobile CPU in BGA1168 socket (soldered)- is needed specialized equipment, knowledge and skill to do.

and why do you think it is soldered?

it may be soldered.

 as I said the cpu is accessible .

I will take a look at cpu when I get my parts to control the fans.

LOOK INSIDE! those screws release the heatsink of the cpu and I have looked at them.

 So I can tell you  you may be right the cpu was soldered in but it is accessible and I am not certain it was soldered in.

Not all mobile cpus are soldered in.
