Topic: KnCMiner Jupiter Miner First Impressions - page 6. (Read 65993 times)

I wanted to compare the performance and efficiency between the two types of power supplies.

Seems the OCZ consumes more power than the corsair as it should considering the corsair 860i is platinum efficiency rated.

And one can see from the results that the corsair ax860i gives better performance, perhaps due to higher power efficiency.

I gauge performance by the total accepted shares.

Do you mean that with 1250!psu have better result from 860 psu?

Here is the detailed results comparing Unit #1 Jupiter between OZC1250 and Corsair AX860i Power Supply

Recent Test 1 day on OCZ1250 Power Supply - Firmware v0.9.5


Past Test 1 Day on Corsair 860i Power Supply - Firmware v0.9.5

Here are the results from 4 Jupiter systems running 24 hours on firmware V0.9.5 in an ambient room temp of 19°C with case cover on.

Note that I had to restart the test due to Jupiter3 restarting cgminer 6 hours into the first attempt. Since then I have replaced the intake fans on Jupiter3.
I have also included the power supply type I have been using on the Jupiters. I found that after 24 hours the Corsair AX860i(580watt) outperforms the efficiency of the OCZ1250(605watt) on Jupiter unit #1

From the results, your unit is operating within spec. What your ambient temp is?

thanks for sharing !

you are a lucky men you've got uor jup and it is very good quality one .

and what's the hashrate reported by your pool?

cg miner now is 542, 2,2%, restarted yesteday

Meh KFC is giving cgminer a bad name
Maybe we should sue them for that.

It's an old version and their driver doesn't do the MH/s calculation correctly either as we saw when they did the big video boasting "It's more than 500GH/s" but it wasn't more than 500GH/s

The HW% is in the API summary ...
e.g. Device Hardware%=2.2219

stay there and don't move

564 @ the pool or on cgminer? 

I will not go to 0.96.
0.95 is great for me.

Firmware 0.95
-560W
-545Gh/s
-50C°
-2% HW errors
-open case

A little update: after running my Jupiter for 12 hours on 0.96 (on Bitminter) things seem to have gotten a little bit better. HW errors went down to 5% again slowly and now seems stable, hashrate is at 505.9 Gh/s avg on cgminer and WU is at 7446/m. Still not satisfied but at least I know you have to leave it running for a while first to see the results of a new firmware. Hopefully I can tweak things to get it hashing a bit faster towards 550Gh/s avg with 8k+ WU figures and 1-3% HW errors like I see the good Jupiters perform.

so according to the numbers, this means that I have like a 20% error rate, and thats why on the pool server I show THE TRUE HASH RATE OF 210GH/s.....correct me if I am wrong, but I think this is how this reads....

Kano, any thing that can be done to correct this.....is it firmware to hardware, hardware to software.....I notice on .96 that when a block is found, the miner regains speed quicker...would like to see the 20% errors go away, then maybe the pool server will truly see 250GH/s.

hey kano, care to explain a little more for us dummies, thanks.

if this works, a little velcro will make them stay....

DPoS, I thought the pool server stats were the ones that counted.....anyhow, do you or anyone else know of a thread were it gives specific instructions on accessing the Saturn via ssh for a total newb....I know I can figure it out by doing tons of research, but hopefully someone has condensed all the instructions???

how are you seeing 1%?   The HW error rate is the real killer.  You can see that either by viewing cgminer or running bertmods acis_status.pl / get status page

you'll see either something good:
Device Hardware%=3.2182

or crappy:
Device Hardware%=14.1518


one of your boards will show something like this if you checkl:
    

Temperature sensor: 36.0 C
Die ID    Cores ON Cores OFF %
0   36   12    75
1   48   0    100
2   48   0    100
3   48   0    100

Are we supposed to press the black button to overclock the unit?? How would that work? I have 0.95 firmware...
