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.

not comfortable applying 0.96

but willing to try edit/config/cgminer.conf

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

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)

I didn't do any mods except leave my top off the box and use it as an impromptu mining table for my new mercury and tons of extra metal.  There is no extra cooling going on.  but if I took my 140*4 that would avg 560 GH still?  I get it that there is more airflow needed to keep the heatsinks cool...but if the case is open then open air should still be adequate right?

No, it's with closed box. I think the lid has to be on to get some air pressure inside.

On the other hand I've removed the two blades from the lid.

I'll open it and shoot some pics.

Hi trepex as usual great info shared here Tongue 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   Cheesy

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

I will try to get an OK for publishing my (ugly) modified perl script to display the temperature and active cores.
That's the only information I really used for manual tuning at the moment.
I did ask the author (in the KnC forum) if he could publish an ASCII (terminal) version of his tool, never received
an answer there.

My fan had been loose inside that black "cover", the screws you see did nothing! Just decoration!
That had been fine with the original setup, in my setup it would not work. That's why I did use the pure
fans. There is one screw that holds the fan from sliding away from the heatsink. The rubber band (must
find 2 more to have a redundant rubber band installation) does the rest.
I think the asic heatsink is oversized (that's good!) and the cooling for the VRMs is undersized. That's why
I tried to get more airflow on the VRMs and a little bit less on the heatsink.
The additional fans on the side help cooling the heatsink.

Performance:

It looks like my performance did go up (average Gh/s over >12h) from
260-265 (no modding, case closed)
265-269 (case open, 2 fans on the side)
269-272 (case open, 2 fans on the side, 1 fan on top)
272-275 (current setup, 90min average only)

Are those lying fucks at KNC going to give us a "daily" update today??? It's Wednesday and if I'm not mistaken that means we should be on our third update this week by now.

I guess because they lied last week about the "3-5 days behind" on production (day 6 now), they have gone back to head in the sand mode. Pathetic.

Today I'm down 8BTC since they failed to ship by 15th October. That'll be 9BTC tomorrow. I'll never see that back, unless KNC man-up and compensate the people they are in the process of screwing.

If they are compensating the guys who they screwed on the hosting, why is it any different to compensating they guys they are screwing on their falsely advertised shipping dates? Why should us individuals take the pain of them over-promising and not delivering? Why don't they accept THEY made a mistake, they fucked up and they are responsible to make good on that?

Another couple of days and the difficulty is due to shoot up again, making our units more and more worthless before they have even arrived. I've been hauled over the coals here financially by dealing with KNC.

But karma is a bitch and if they don't compensate us guys they are screwing right now, it'll all come back to bite them on the ass sooner or later. Hope everyone's conscience is clear as they count their profits.

Above all else we will be fair.

Sam
Haaaaaaaaaaaaaaaaaaaaaaa!

Making your customers take it up the ass because you fucked up is not fair.

oki returned.) it seems, that they really fixed "flushwork issue", because not it takes ~2sec without any hashrate impact. for real results, you have to wait long hours.)

I got a HW decrease on 1 unit and Stabilizing of Hashrate at 520 from 460.
BUT on another unit HW has nearly doubled with same Hashrate as before.
Strange things happen around me lately.  Huh
