KnCMiner Jupiter Miner First Impressions

[sickpig]

It seems a good result, no? ( as long as it last for a few days at least)

How stable temps with the case on?

I am seeing one chip on each miner run hot even with a big fan on top like you had.. might add a crossfan

I have a Corsair Gaming Series 2013 Edition GS 800W ATX/EPS 80 PLUS Bronze Power Supply Unit, is it any good for the Juniper? Also I am thinking of getting    
LEPA G1600-MA-EU, so I can plug two together. Also I am considering getting Corsair HX850 Professional Series HX 850W ATX/EPS Modular 80 PLUS Gold PSU. Is this one any good?

ps: I purchased 2 Juniper, the GS 800W is currently connected to an ASICMiner Blade.

If its an old ps from your gpu mining days then it may be worth considering.

However
I recommend what I use.

AX860i
http://www.corsair.com/en/ax860i-digital-atx-power-supply-860-watt-80-plus-platinum-certified-fully-modular-psu.html

I have used it with Avalons and will continue to use them as long as the power requirements are in their operating spec range.

You only need the AX860.  The AX860i includes a module that will only add function if it's used inside of a PC.  There is no other difference... save $20.

yes

which is slot 4?

Open the case and feel each heatsink.  Three will be warm to the touch and one will cool.  The cool heatsink will be slot 4.

64C is not hot for a chip.  Don't worry.

Is that your results with the case cover on or off? Do you have any added airflow? Also what GH/s does the pool say the unit is running at?

The great thing is that cgminer does not restart with firmware v 0.9.4

Here are the results since the update to firmware v0.9.4 using case cover on and original fans.




As you can see. The performance reported by cgminer is the same as when the system was using firmware v0.9.0 with the case cover on and stock fans.

Later I will be removing the case cover and put the fan pointing down back on the unit to see if it improves performance.

I will do this with out restarting the unit in order to see if the Work Unit (WU) submitted per min goes up from 7600 back to 8200+

64C is not hot for a chip.  Don't worry.

It is for an off-die sensor. Actual temp could be 10-25C higher in the core itself. I don't have a clue what KNC is using though.

I also agree. As you can see my ASIC CPU temp is considerably lower then those others reporting.

I will see what the ASIC CPU temp change is when I revert to my temp cooling solution.

you seem to have a better temperature distribution across slots, those are mine

miner running with 0.94, before running with 0.91, unable to run with 92/93 due to cgminer frequent restart.
with 0.94 I get higher hashrate, something like 3-4%, HW error of 7%.

still they didn't solve the problem mentioned here:

https://bitcointalk.org/index.php?topic=18313.msg3294238#msg3294238

I am seeing higher stale rates from KNC equipment so it looks like they are not flushing work when the stratum server requests but are instead finishing old work and submitting it.

every time this happens you'll get this line on cgminer output:

 [2013-10-09 19:42:36] Stratum from pool 0 detected new block
 [2013-10-09 19:42:36] KnC running flushwork
 [2013-10-09 19:42:36] KnC: accepted by FPGA 1 works, but only 0 submitted
 [2013-10-09 19:42:36] Rejected 00815da7 Diff 506/326 KnC 0  (Job '26017' not found)

and your hashrate will climb down and rump up within a 10 sec

I was just going to mentioned that... seemed like it was acting dumb with all the dupes, etc

[DPoS]

I added some more fans as crosswind and some cardboard shrouds to make the temp lower..everything is under 60 now

as far as hashing, BTCGuild is telling me both are around 450 now..  I think the dupes are killing it (not flushing, finishing old work)
I don't really care what it says on cgminer since that doesn't translate into BTC

So I chopped this out of your images:


So to turn that screen into real numbers:

Elapsed = 18347s (5hrs 5min 47sec)
Accepted = 1970688 1diff shares
Rejected = 1536 1diff shares
Hardware Errors = 347881 1diff nonces

Accepted (paid) hash rate:
2^32 * Accepted / Elapsed = 461.3GH/s

Full hash rate:
2^32 * (Accepted + Rejected) / Elapsed = 461.7GH/s

Hardware Error%:
Hardware / (Accepted + Rejected + Hardware) = 15.0%

Hardware Error hash rate = 2^32 * Hardware / Elapsed = 81.4GH/s bad

I think we need to stop calling it cgminer ... maybe KFCminer?
I see no GPL3 source code and we can't be blamed for that version ... we had nothing to do with the driver
(and have no idea if they changed anything else or not)

Thanks for that Kano.

As of this moment I took the case back off and put on the external fan on top pushing air downward to move the hot air around the components.

This is the result.

[DPoS]

that's some low temps

it wasn't hard to see that they slapped a shoddy case/flow design together.  My makeshift fans/shrouds keep improving the more I put time into it.

I will think about getting some really blast fans and then perhaps reuse some of the lid metal in a better flow design

Kano make a good firmware for Jupiter please
