how are you guys powering off your unit? i just got mine today. when i first got it going i was hashing at 667 and my pool also showed 667. i did a power shut down by turning off the psu and changed it to some other psu. then powered it back on and now i'm at 567 and pool is at 399. anyone having the same problem?

Sounds like it may be a module issue. You may wish to check with knc support as I am not sure batch 1 firmware tools work on your new unit.

That is weird that there would be so much variance in reported power.

Most units are in the ~600W +/- 10% range and then there are some >700W? That can't be explained by differences in power supply efficiency.

There are PSUs with 92% efficiency and there are PSUs with 80% efficiency, so that might be the case.

My Jupiter is using 700-800 Watts at the wall. The ASICs report using ~400 W. Anyone have an issue like this?

That seems insanely high how are you measuring wattage at the wall.

Kill-a-Watt

What firmware are you using? Same for waldohoover.

No.

In my Jupiter with FW 0.98, Bertmod reporting 572W, it's taking 668W at the wall, with OCZ 1000W Stealth PSU. Before, on FW 0.97, it was around 500W on BertMod and 580W at the wall.

What FW you're using?

0.98, Bertmod reports 555 W DC-DC. I use two PSUs, a 750W and 800W. Hoping to read maximum efficiency at 50% load.

Has anyone tried using 240V?

I am on 240V Europe. 668W on 1000W PSU on mine and yours are using 700-800W. You should read buy better PSU.

I'm on 240V in New Zealand, my Jupiter setup:

SeaSonic Platinum 1000W ATX12V power supply
KnCMiner firmware 0.98.1
640W at wall
Bertmod reports total DC/DC power output: 567W
550GH/s on pool as I type this*

* I'm super happy, I don't know why it's going so well right now, but I daren't touch it. On 0.97 I was getting about 330GH/s. On 0.98.1 the last few days the hash rate has varied, and I'm taking the precaution to reboot every night (as I did with 0.98). This is because the hash rate at the pool dwindles down over time. I would normally reboot now, since it has been a day since last reboot, but I can't bring myself to reboot since the performance is so good.

overclock tips?

thanks

I think 140GH/s per chip is the maximum, so not much room for overclock.

I'm getting 144GH/s per chip without overclock.

Ok then that's the maximum. Someone posted a formula with cores and speed, but i don't have it at hand, but you cant push chips faster than that because it's already their maximum.

Stability is also important.

Thus far firmware v0.9.8 has been stable.

Haven't tried 240, but I'd recommend a nice 1000W PSU over using those other 2 *(not sure what they are, not sure if an 800 could power all four modules)* - but I'm pretty sure you're pulling more power from the wall than you would with 1 really good 1000W PSU.

Personally, I'm running a Seasonic 1000 platinum and my Jupiter is now reporting 564 at the web interface (been running 4 days now, was at 563 for the last couple days) -- pool reports anything from 520 to 600.

Back on topic, I have no idea how much I'm pulling, (I'm running 0.81) but the PSU barely even gets that warm. (If I had to guess I'd say around 10-15 degrees above ambient - regular mode, never tried the hybrid mode)

Bottom line. Even though I can't test the power at the wall, the low temperature of the PSU leads me to think that it is extremely efficient at whatever load it's pulling. I highly recommend this PSU as a great choice to power a Jupiter. (just my personal experience, and no, I'm not getting paid by Seasonic)
