Topic: Review of Panda Miner coming up. - page 6. (Read 30761 times)

Have not bothered trying dual.

I am excited  with simple mining  as it shows fan temps.

 I now have a 3 card rig using a USB3 stick
I have a 1 card rig with an msata in a sata case

see below
I will run overnight and put the msata in the pandaminer
If it runs well I will make another msata and keep them as backups
So crashing  due to the hdd drive will be done.

My goals will be run  3 or 4 pandaminers
And 1 or 2 gpu rigs.
So after I test the msata overnight  I will put it in the pandaminer and test that.
Down the road I may switch to the os+rom from Eliovp.  It appears to be better then any other setup for pandaminers


screen shot before second rig got the msata




updated screen shot

Any experience with dual mining? I tried ETH + DCR (both Nicehash - 222eth, 3360dcr) and after 15 min. it crashed

I have been lazy I did not bother testing them.

I made some progress with simplemining  made a usb 3 boot stick .  it works on my 3 card z270 board
see screen shot below.

next step is make a msata and boot it  on one of the test rigs first then use the msata in the panda miner.

this will give me  temps of the cards .

I mine in a hot spot  so my pandaminer has crashed at lower fan settings
7.5 volts I crash.
8.0 volts I crash
8.5 volts I crash
9.0 volts kind of stable
9.5 volts pretty stable
10.0 volts to 12 volts stable.

if you drop those in you may crash if fans go too slow.

cooler rooms can do 9 volts  and sound is okay  not good okay

here is simple mining

I just received my pandaminer 2 days ago, running smooth using their stock claymore miner, but when replace to new claymore version 7.4, after 2-3 hour I got watchdog error.

Phil,

Would these 47.3Ω resistor fan cables work? They're super cheap, so I'm wondering how much of a difference they would make on the panda fans. They sure look like an easy drop in solution to the noise problem...

Keen to hear your thoughts.

Maybe this was covered elsewhere in the thread but I got here late.  At any rate the default KMS key is set automatically on volume license windows media.  So basically Phil in the first post the reason you are seeing evidence for a KMS key is because it had been installed with volume license media. 

When you buy enterprise licenses from microsoft you get two types of keys, MAK (multiple access keys) and KMS (key management system).  The MAK key is similar to the one most people are used to, you enter it in the OS when you first boot it and it activates online with Microsoft.  In the case of volume license media you just get to use the same key many times but the process is exactly the same as when you activate a home version.  You enter the key and it activates online (or you can go through the activate by phone thing).

The KMS keys allow you to setup an activation server on your network that automatically activates certain versions of Windows (or other MS software) without the clients having to connect to the internet.  If you setup a KMS server on your network, all you have to do is install the client computer from the volume license media and it will get the default KMS key and try to find an activation server on the local network to activate.  So basically KMS is easier because you don't have to enter a key on the client computer when you install.  You just install from volume license media, boot, and it finds a local activation server and activates without any intervention.  So if it is installed with volume license media it is already setup to try and use KMS activation. 

Those pirate things you posted screen shots of are basically online versions of the KMS activation server.  What those pirate software guys aren't telling you is that KMS activated software has to reconnect with the activation server on a regular basis (I think once every 6 months) or it deactivates.  As long as the pirates have that activation server online and accessible, then a pirate copy you activated from there will work but the clock is ticking and 6 months after Microsoft takes the pirates offline those copies will all deactivate.

The default KMS keys are not a secret.  Here is a microsoft page with the list for Windows products: https://technet.microsoft.com/en-us/library/jj612867(v=ws.11).aspx  You will see the one you noted in your first post listed there I believe.


So the TL;DR version is that it had been installed with volume license media and had not been activated and the key had not been changed so it still had the default KMS key.  That is not evidence of pirating or attempted pirating.  It just means the panda guys used a volume license version of the windows 10 installation media.

Yes its is...
Last year, my GPU farm ... 30 x Windows rig, 1 x ethos, 1 x SMos, 1 x Ubuntu-14 rig
Jan 2017 transformation, same farm.... 32 x SMos and 1 x W10 (test rig), 1 x Ubuntu-14 rig (test rig)
The Panda's mSata, I replaced it with SM image, so no SM USB bootup.
Most of the Windows rigs had 120Gb SSDs, simply replace Windows with with SMos image.
Around 6 new rigs uses SMos USB3 thumbdrives for fast bootup.
Results.... very stable farm & monitoring with Claymore ethman, less sleepless nights  and more time to learn Linux.
Just waiting for SRR to complete the whole project to achieve lights out operations.

I see reports that Simplemining.net Linux OS works well with Panda Miner.   Pretty cool OS as everything is loaded onto a USB drive.  Easy to use even for a Linux rookie.

the cpu exhaust = 89 f only 1 fan

the gpu exhaust = 101 f 2 fans

this is with the fans at 9 volts in a 87 f garage

Philip is correct - the CPU fan is on the outtake side (back) not the intake (front) side.
This is logical since pulling air out would give better results to cool down CPU.
No point putting an intake fan for CPU hole - the blank hole/vent is more than sufficient.

Thanks for clarifying that. I don't think anyone is worrying about CPU cooling.

Do you think it's possible to move the CPU fan over to the intake side so it acts as an intake fan?

my unit has
4 intake and an empty hole.

it has 5 exhaust

and  the cpu uses 15 watts  with 1 killer fan and the empty hole


2 gpus use 180- 220 watts  with 2 killer fans  in push pull setup. 


 there simply is no need to worry about the cpu cooling the stock fan is 2x or 3x what is needed.

The two statements in red sound contradictory, so I'm still unclear on the fan configuration.

How many fans pull air into the panda, vs how many blow air out?

If you have 5 intake fans and 4 exhaust, it's good because you have positive pressure inside the panda, which helps limit how much dust gets in.

OTOH, if you have 4 intake fans and 5 exhaust, you have negative pressure, which means the panda will pull in air from the remaining 10th fan hole and possible from other cracks/clearances...

Ok, i still think pluggin it, would increase the air pressure inside for better airflow, but putting a 10th fan could also be good. Strange design they made, maybe it was a mistake or the case was planned to be 10, but they noticed that 1 would be enough. Thanks for the added infos man.

there are 10 holes  with 9 fans and 1 empty space

the empty hole is on the intake side

So the hole is on the side that bring air into the panda, not the side that expel the air outside ?

no it will not work.

Ah i see, well for air flow, it could be good to actually plug this empty hole (with a flat piece of plastic for example), because it make the depression of the pull/push system lower. has anyone tried that ?

ten holes  nine fans  is what came to me

there is a jack for the 10th fan there are mounting holes for the 10th fan.

if you do a full tear down  and you need to pull the mobo out of the case to remove any of the fans.

So  you  could do  that  pull the included cpu fan  as a spare for the eight gpu fans.

You could put in this fan

https://www.newegg.com/Product/Product.aspx?Item=N82E16835230025

this would be good enough to cool the cpu.


if you went for this mod it should be fine even if you do the other mod  and send 9 volts to all fans.

If you buy the gear for the fan controller from amazon  and buy this fan from newegg  you are at :

7 wires + 12 controller + 7 fan = 26 bucks.

It looks like  using 9 volts and 38 watts  keeps the pandaminer stable in a 92f room

I am mining zec  at about 1660h
I am using clay 9.1  intensity of 6  and ssl

I use well under 1000 watts  about 974 at the meters. this includes the fans  which I am doing external power.

When the linux build is released this should get a lot of improvement.

Would I buy more pandaminers?

 yes I would  and I am going to  once I get Eliovp's linux build.  For now I am not getting a second one.

Yes, just wondering what was in place of this fan, if hole empty or no hole @ all.
