ive updated to .98 right when it came out and noticed that i was yielding 15-20 gh/s more than previous firmwares.
i was hash around 565-570gh on the pool and this was shown on cgminer as well, but today i noticed that cgminer, bertmod and pool is displaying a decline in hash rate (cgminer showing 550gh down from 565gh), any idea why this is? the temps on the unit remain the same and i havent touched anything since i updated.

I too am noticing the same-old "Dwindle-down" of hashrate over time, and have to run "enablecores" on all the machines to get back, which lasts about 8 hours...before I really start noticing a drop

Are you sure you're not just looking for another reason to futz around with your miners? Grin

I think, November miner deliveries has already been shipped and they reach customers today.

Customers can start hashing from tomorrow, 00:00. Shocked

For those people having trouble connecting to *some* pools out there (the ones using round robin for DNS such as eligius), I have built a binary incorporating some upcoming changes to cgminer that hopefully should help:

(For advanced users only since you have to copy this to your knc device under ssh as per my first binary upload).

.98 is much better on p2pool. My Jupiter went from 440GH/s to 530GH/s. Nice work KNC and Con.

Hum. Take the machine apart, run it at temps well outside what the designers intended, act shocked when performance drops.

Is anybody else shaking their heads?

Shocked

I'm shaking my head. In my experience miners run better and longer when they run cooler.

I had no idea this Jupiter was from another planet. Wink

Hmm wellll -- Jupiter is another planet as I recall...

My Saturn is running at about 50 to 52.5. Hash rate is 282 GHash to 303 Ghash is short bursts.

There seems to be no need to heat it up.

you missed the whole 'let's yank 4 VRMs off and ship firmware that bakes the remaining VRMs well over spec and flood the chips with HW errors' part of KNC history right?

btw... of all the experimenting on the sats...70-79 seems to be the optimum temp
It takes about 1 and 1/2 hours to 2 hours to see the results on the graph, but looks to be a signifigant difference when you include several machines... about 40 gh/s for me... just by monitoring temps to 70-79 instead of letting them drop to 55-60 overnight. I use cardboard to block a bit of the airflow, and monitor the temps on the GUI, then watch for the results on the graph, and how high they peak over a couple hours. Well worth it for me.
When they said "Over-cooled", they weren't kidding!

I'm running naked case with a huge blower fan blowing across it and my temps are low 40's but the hashrate reported is only around 450. I turned the blower fan off and my hashrate jumped to 550 in fairly short order (less than half an hour I think, probably closer to 15 minutes) but when I noticed that the temps were going into the 70's I immediately turned the fan back on, and the hashrate promptly dropped back to 450.

Does anyone else know about the longevity concerns of running at 70+ degrees? Anyone else noticing similar results?

This is on 0.98 firmware btw.

it was asked to knc, and posted as an email reply... yes the machines are rated to run up to 105 C, and 70 is well within that range... I experimented for two weeks now on 3 different machines.....the sweetspot is right there in the 70-75 range. Since each asic board is different, I customize each thru airflow separately.

I was getting 460-480 on eligius. .98 got me to 520-550! Woot! Good stuff.

Did someone noted or ir aware if KNC already upgraded the hosted boxes to 0.98?

My hosted Jupiter jumped from ~490 GH/s to ~560 GH/s like 24 hours ago. I have previously seen similar changes, both negative and positive, around the time they release a new FW version. I think they pretty much upgrade all the hosted miners as soon as the new FW is ready, but I could be wrong.

Here are some steps to streamline access to your miner through putty..
1. Open the putty session window, and input your I.P. normally, but do not hit enter.
a. Instead, take your mouse pointer, highlight the saved sessions field, and input your miner's I.P. again.
2. on the window/behavior tab to the left, un-check the warn before exit box.
3. on the connection/data tab, enter "root" to the auto-login username field.
4. on the ssh tab, enter "screen -r" into the remote command field.
5. back on the session tab, at bottom of page, check the close window on exit "always"
6. now hit the SAVE button, and close putty
7. Go to your desktop & right-click for a context menu, and go to new/ shortcut.
8. input the location of putty for starting it. Use full file location to execute putty & input your miner's I.P. address as such...
C:\Users\Ewik\Desktop\putty.exe -load "123.123.123.4"
click next, input a name for your new shortcut, click finish.

Now, when you click on the shortcut, it will start putty with your miner's ip, and enter "root" for you, and wait for a password. as soon as you enter your password, it does the "screen -r" for you, and jumps into cgminer window.
it all happens very fast then
click on shortcut, enterpass, you're in.
BAM

Thank you !!

Those are good points I guess there is no way to give access to just the web interface and block ssh access.
If not I guess the renter would have to prepay enough to justify the risk.

As I said, the root password is not the same as the admin password, you can change the root password to be different to the admin (web login) password.

So change the root password and they can't ssh into the box, they can just use the web admin.

To change the root password from ssh just type passwd

Try it, change the root password, then logout of ssh and login again with the new root password.

You will notice that the web account still uses the old password.

If you want to change the web account password its: passwd admin

I don't think that's actually true... The lighttpd daemon has it's own password file and pays no attention to /etc/shadow for its authentication.

Hell?

just a bit of an update. my mercury is running at 134.4 ghs (from the pool) 141.6 (from cgminer) since .98 firmware. everything is running great except hw errors actually went up for me. its steady at 6.9% and rejected (duplicates mostly) is around 3%. could be worse i guess...
