Topic: Review of Panda Miner coming up. - page 2. (Read 30761 times)

seems like a poor way to make a miner. stock it should be able to handle dual mining, or any other algo you toss at it.

its like buying a sports car and them telling you "oh yeah, dont drive over 75 mph and also you will need this special, extra cost engine computer to do it."

if i can dual mine on my home built rigs, i would think a professionally built miner could do the same.

Or you:

1. Do NOT dual mine
2. Use a decent rom so the gpu's don't require a shitton of power

No issues whatsoever so far.

well the 2 split cable are pulling more juice on less wire.

and if the pins are flawed in the least  it is a double stress test on 2 cables and 4 sets of pins.

So look for more of it to happen  as the summer heats up.

of course bad cables would cause a melt down.  If they are too thin to handle the amps.  But an improper connection as in loose on the pins would cause the same thing.  I bought extra plugs to combat this lol.

Umm... Bad cables would cause cables to melt, not the connectors. This is more likely due to the plugs used on the cables being bad quality.

my guess is you will see more meltdowns as it gets hotter.

it is the two split cables  meaning 5 cables not 7   and they seem to be 18 gauge not 16.

yep they seem pretty decent but I can see where it would be the PSU.  I have 36 of them and thats the first I have seen ant it was a 90 degree day

I had great success with this one

 evga 1600 t2
 rosewill tokamak 1500w titanium
 evga 1600 p2
 evga 1600 g2

all of the above are good the rosewill is very good value


evga 1300 g2 --------- do not max the gpus

Phillip what PSU do you rec for these?

were you using the POS  oem psu?

Mouser has them.  I just had to make a repair like that on one of my B1's.  FYI it's a total whore to fix, take your time.

Links?

I guess so, started to see alot of complains about this issue..

Has this become a common problem for the pandaminers?

So I take it easy with hercules. Ok, I wanted to run eth+dcr but I'll probably do it with the others

's
duh you already own psu's  completely different advice  the gold evga's are fine

the hercules is tricky it has 2  12volt rails   one is 50 amps and one is 110 amps  those rails  feed different   cables.

So let me look around and figure out if it will work.

look below  it will be a problem but still can work  only the 110 rail will use the pcie cables so you really have a 110 x 12 = 1320 watt psu when it comes to the panda.

run that panda on zec and you will be fine

All of the PCIe connectors are available via modular cables, as are the 16 SATA, six Molex, and two FDD connectors. The only hardwired cables are the 20+4-pin main power and two EPS12V (one 8-pin and one 4+4-pin) cables. The sheer number of connectors means that the HERCULES-1600S should support most any hardware configuration. Rosewill designs the HERCULES-1600S with two +12V rails; one 110A and one 50A. The 110A +12V rail is engineered to support your graphics card subsystem. The 50A +12V powers most everything else you connect. The two +12V rails are rated to deliver up to 1,560 watts. It’ll be tough for any system, even a quad GPU setup, to come close to taxing this PSU. Rosewill rates the HERCULES-1600S to deliver the tremendous load continuously at 50 degrees Celsius. Safety Mechanisms

To protect your GPUs and other system hardware, the HERCULES-1600S monitors the rails for over temperature, over current, over voltage, over power, under voltage, and short circuit conditions. The HERCULES-1600’s 135mm fan also stays on for a few seconds after the PC turns off to remove any residual heat. Speaking of the fan, Rosewill includes a Turbo button at the back of the power supply to let you boost the fan to its maximum speed. The Turbo button is ideal when you’re putting serious stress on your rig. You’ll know when Turbo mode is activated, because the fan noise is noticeable. The 135mm fan also features PWM speed control, when not in Turbo mode, to let the PSU ramp up rpms only when necessary.

I have 2x 1600w gold evga and 1x 1600w gold rosewill hercules. I still need to buy a few more psus for the pandas but can I use those gold ones I have? Have you seen psus risk messing up the the mining system?

With all due respects, I had a very terrible experience with Rosewill 1600-watt PSU purchased from newegg 2 years ago. It fried my S5 then another S3 right out of the box. Rosewill was known to offer cheap products. You may want to use a meter to benchmark it before applying directly to your rigs. Just my two cents.

the gold has 2 rails  not a good thing for mining.

the titanium is highly rated by jonnyguru

I respect his opinion  he likes this psu and that  was based on a price higher then  the one on ebay which is rosewill's ebay Store

plus I ran the pandaminer for 75 days with it and had zero issues

What about the gold? http://www.ebay.com/itm/Rosewill-HERCULES-1600S-1600W-Modular-Active-PFC-ATX12V-Power-Supply-Gold-Cert-/191921783870?hash=item2caf6e043e:g:mroAAOSwzLlXhsA6

Or do you recommend going with titanium despite the 100watt difference?
