Do you have a Jupiter 2 then as well? Why did I suddenly think of 'Lost in Space'?

 Those are some low HW error % !!     

--------------------	0.94	0.95	0.96
Average CGminer	270Gh/s	274Gh/s	280Gh/s
Average Pool	275Gh/s	263Gh/s	278Gh/s (link)
Consumption	485 Watts	305 Watts	313 Watts
Temputure	54 & 62°C	42 & 47°C	42 & 47°C
Rejected	1.5%	0.22%	0.38%
HW	2.81%	0.79%	1.08%
WU	3975/m	3717/m	3933/m

0.94	0.95	0.96

Anyways I'll stick to firmware 0.96.
From the beginning I wanted to mine on Eligius and with firmware 0.90 to 0.95 I had the flushwork issue.
It seems that 0.96 solved that issue; it's been 24 hours that I'm mining on Eligius.

I'll post something in a few hours.

Could someone please summarize their findings with the last firmware versions? Something like these data points:

- Firmware version
-  Power consumption
-  Hashrate
-  Temp
- Errors, etc/

I think this would help distill some of the long discussion here.

VRMs temp is veeeery hot 

I need RAM cooler

still to early they've just received the code and the miners are on their way....

now anybody could look at knc cgminer source code

http://www.kncminer.com/userfiles/file/cgminer_knc.tgz

driver-knc.c contains the knc driver

does kano or jr luk

make any patch for core on the core off asic chip?

Thanks for that update. I am noticing that Jupiter 1 and Jupiter 3 are not at optimal performance. I will test them with firmware v0.9.6 in the next 21hrs.

Tried 0.96 for awhile and found it gave me a higher WU/m then 0.95.

However, 0.93/0.94 still gave me the higher WU/m so I'm back to the old firmware.

now it's clear KFC...

I was referring to a KFCminer

Hi Kano

here 'Orama said he sent the cgminer driver source code to Luke-jr and ckolivas, so I think you'll be able to see it easily

https://bitcointalksearch.org/topic/m.3358406

1hr result with firmware v0.9.5
Not much different at this time.

Only Jupiter unit 3 seems to be performing similar to  Jupiter 1.
I will swap out the intake fans on that unit and also apply the heatsink fan relocation trick that was posted by DPoS






2hr Results


3hr Results

Here are photo's of the unboxing.

New V2 4VRM Design




Same default low CFM intake and cooler fans.



ASIC Modules Assembly line #'s
Note: we have noticed that ASIC Modules with #1 has better performance overall however it may be a coincidence.




Bent ASIC Chip Cooler

I did similar thing, but I put 2 extra fans at other side of unit, pulling air out:

With all the activity on the thread, I have a bit of reading to do in order to catch up.

However I just wanted to update on the status of the shipment that I have been waiting on.

I will post the unboxing photos and a few preliminary results before I get down to 12hr and 24hr testing.

These came packaged the same as the first unit back on October 4th.

The same issues on this batch, cooler fans being detached during shipping, and one ASIC Cooler heatsink was bent. Apart from that nothing out of the ordinary.
The units shipped with firmware v0.9.1

Here are the results after a few minutes.

Doing a baseline on this new hardware with firmware v0.9.5
I have Jupiter 1 on an OCZ1250 Power Supply The others are on Corsair AX860i
