Bitcoinorama has said in this thread something to the effect,
there will be a 30 day pause between the first batch and the November orders.
(he was passing along KnCMiner statement from Sam I think)

If that is 30 days from end of september, then that wont be much of a pause.

[Nemo1024]

im highly considering asking for a refund.

I've already got my November-Jupiter refunded.
Still sitting out on the hosted 39xx Saturn (will give them one more week or so before asking for a refund), though people after me in the queue started receiving their miners. My hope is that Saturn can be later upgraded to gen2 Jupiter (sometime close to the end of the 6-month hosting period) and shipped to me.

Well considering i am  6XXX order and a mercury i got a feeling i will be having to wait awhile. Unless someone wants to buy it for me at my cost of buying it. Order price: $ 1,995.00 Shipping price: $ 102.60(One day shipping) Total price: $ 2,097.60

can use John.k or DannyHamilton for escrow at your expence.

Good work!!  

 and yes another way to keep cgminer from starting and turning off cores is to just change the first { to a } in the cgminer.conf so it runs but just sits there (screen -r and just quit it)

my one die being off is probably saving enough watts so my 850psu doesnt roast...  I'll pick up a 1000W or 1200w tomorrow


Edit:

3rd time was the charm!

DPoS I'm really glad that you're able to sort that out, so now your "faulty" jupiter is not faulty anymore

Let me just do a quick recap:

0) someway u were able to set input voltage for you miner to 0.9V
1) u've tweaked the cgimner.conf fiel in such way that cgminer start but do nothing (so no enable/siable core dance anymore)
2) run enablecore repeatedly trying to maximize the number of working cores.  
3) use Like-jr bfgminer instead of cgminer to mine

is this right?

a few other quests:

a) is this jup a 8 VRM  or a 4 VRM one?
b) which is the version firmware currently used on that box?
c) wattage at the wall?
d) u get a die completely turned off on one of your asic board, right?

thanks for sharing your experience.


edit1: theoretically with a 1200W CPU we could turn a good miner into a super miner using this procedure?
edit2: do you have lower system load while using bfgminer (uptime command output)?

[jelin1984]

i have jupiter with 4 boards number 1 all
4vrms
but the speed with 0.96 firmware is 530gh only

does anyone know what to do to have more hashing like 550 gh?

Two of the heatsink fans off & resting on the crossbar at a downward angle. (ill do the other 2 later)

Yeah, great idea!
(Don't do it in an earthquake region!)

Here is my setup. I removed that external case for the fans.
The results are great. The BertMod (modified ASCII script) reported temperatures dropped by 4-5C:

Old setup (with two additional fans on the side, one on top):
Board 0: Temperature sensor: 40.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 40.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

Modified Board 3 (the right one looking from the BBB):
Board 0: Temperature sensor: 41.0C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 37.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

Modified Board 0 as well and waited 10 minutes:
Board 0: Temperature sensor: 36.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 36.0C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

This setup also cools the VRMs much better. I had two ones (same location, see picture!) with a temperature of
51-52C. Those are now at about 47C. The only side effect is, that the heatsink is getting warmer. But - it's designed
for that. See the infrared thermometer measurements on the picture.





No temperature reading for the 4th VRM, sorry!

Update: I just noticed that the power usage did go up from about 278W to 282W. Maybe it's running faster

I just did some port forwarding on my router.  Now i can access my KNC page from my cell phone when I'm out to check on it,update or reset, Also set up JuiceSSH app on my android.  So now i can connect to cgminer through ssh on the phone as well.

what is the deal with KNC running Flushwork?

my GH/s rate drops by 100GH when it performs this task... and takes a while to build back up to previous rate

Hi trepex as usual great info shared here if you don't mind you could share also your modified ASCII version of asic_test.pl?

I've noticed you did change fans for the internal heatsink and that the new one are positioned lower than the original, did you considered the DPoS way?

which is why I lowered the fans to get 5-7C cooler  

anyway did you notice any increase in hashrate due to lower temp?

This seems to be what I'm pulling on stock Hash Rate on Mercury does this look good for WU?...right now it's 139GH 2020 WU

Also, I'm curious to know if dropping the stock fan helped at all in terms of hashrate?

[edgar]

OUCH! BTCGuild is down fluctuating, how do we apply a failover pool to these rigs?

use fw 0.96, if you're using 0.95 or lower just edit /config/cgminer.conf manually adding failover pools.

Mine's almost a duplicate of that. Temp is 38c, I dropped the fan but it made no difference on a merc.
Oddly, I'm using my PSU box in the open case ...initially to stop the cat roosting in there..but at an angle it directs air nicely to where I want it.

[demonmaestro]

no issue on my end.

not comfortable applying 0.96

but willing to try edit/config/cgminer.conf

where is this? in the KnC gui or via PuTTy?

[ElGabo]

This is mine.

I spent long hours when it arrived to figure out wich pci-e slot works fine with which hash card.

I've replaced the stock fans with 2 110cfm, 2 150cfm and at the intake in the middle there is one 150cfm. 2 170 cfm intake fans are on its way.

Now the result is this.

Room temp around 19 c.

My hashrate on Btcguild between 520-570Ghash

Now I'm trying to keep my hands off the box. If it ain't broke...

login via putty to your miner.
edit the file you'll find into /config/cgminer.conf accordingly.
pay attention cause the only editor i've found installed on the miner is vi and it's quite difficult to use at first.
to avoid problems imho use winscp to fetch your /config/cgminer.conf, save it locally into your win workstation, edit with your editor of choice, save it and put it back into the miner (via scp)
