How much was hosting again ? Looked like enough to pay staff to me.

Just back from 7 miles with my dog and found my miners down.  Must have been cable work nearby.  

So, here's what I think.  If an ASIC module has one or more dies showing high cores being disabled, shut down the system, let sit a minute before unplugging cables from the module.  Remove the module's heatsink, remove the board from the unit.  Then with some gentle support under 1 VRM at a time, exert pressure down on the flat metal top.  Continue with each VRM supporting under that module as you do so.  Reassemble the unit.  Run enablecores.bin and if you see improvement it's not that the VRMs are providing improved power but that the VRMs are losing more heat from their top rather than there bottom.  When they lose heat from the bottom the heat travels by way of the PCB to the nearby ASIC module and the nearest die will come up with errors.  That one reason the lower the fans to the deck method works so effectively - it passes air between the VRMs and ASIC module.

You all are welcome.  I know this is helping my competition but then I've never been an overachiever.

And if it works, the tops of the VRMs may have been jogged away from the underlying components when the fans got knocked free in transit or struck by a bouncing fan in transit.  If those tops do just snap on/off I wouldn't go just using any old heatsink compound.  I had noticed earlier this year when I built a heatsink for a USB Block Erupter, the heatsink contacting both the CP2102 and the ASIC, if the compound came in contact with the ASIC pins the hashrate suffered.  The stuff is suppose to be non-conductive but who knows.

If you remember the mid-west miner company, they chose the wrong FETs, the problem then wasn't so much the FETs but that the buck-converter got hot and I bet it was the ASIC closest to the overheating buck converter that got most often populated.  I can't understand when the buck converter datasheet clearly stated it will overheat if the wrong fets.  Then that most often populated ASIC would have high errors and they perhaps wondered why.

Nope, I am wrong.  I've had an expensive replacement fan for the Jalapeno sitting here from well before the jalapeno arrived.  I hadn't opened the Jalapeno until just now.  And no, they aren't populating the ASIC space closest to the buck converter in the Jalapeno.  I was wrong.

Case design by a sadist.  Looks like the buck converter is now manufactured by a no-name company as the chip designations were inscrutable and not having the time to research.  I put an aluminum stick-on heatsink on the chip I recall as being pointed out in a photo and put it back together with the new fan.  No improvement but my place is cool so it wouldn't see a great improvement from less heat.  Haven't run their software to determine how many "engines" are functional as I'm using linux and they don't cotton to linux.  I should tho so as to figure out if installing new firmware will be worthwhile.  But this isnt the forum for that.

after less than 3 hrs on 0.97 my fuse at the junction box blew, shutting down everything while i was asleep.

woke up to dark silence - creepy.

switched the tripped fuse back onand we;re back up and hashing.... any reports of similar issues/raised W pulled at the wall?

other than that 540 is now 536 - and WU is now 8147 from 7877

anyone added enablecores to .97 yet?

New trend: KnC miner owners get raided as suspect indoor pot farms.

Hello,
I received a Saturn today.
It comes with FW 0.95.
I update to 0.97 and show 1GH/s hashing.
I try hard reset (according to manual), enable cores, but nothing happens. When I trying 0.96 a red light appears on the controller board. When  I do enable cores again the red light disappears.
So, 0.96, 0.96.1, 0.97 does not work.
Right now only 0.95 works. But with many HW (about 30%). My hashing is about 195 GH/s. Also the cgminer restart often.
I have another Saturn that works just fine. 0.97 282 GH/s 3% HW.
Any suggestions?
Thank you very much.

Go back to 0.90 and run enablecores.

0.97 seems to hate p2pool less than earlier versions did, but still there is too much hate, cannot reasonably use p2pool still.

Although not improved enough to work right with p2pool yet, 0.97 has overall been an improvement for me.

I am mining on P2Pool right now with a Saturn, getting 275 GH/s with WU of 4152 right this sec.

So it's official that 2 Saturns > 1 Jupiter (not by much, but still).

I got lucky with mine - all 384 cores work all the time.

Anyone else had their miner go offline? How long til you got it back online, and how? I'm hoping SOMETHING happens before Sweden wakes up to a new day tomorrow..

Offline here too. It has been like this for a few hours now.

Mine have been running without any of them going offline.

Hey guys,

I have a Jupiter unit hosted with KnC since the beginning. It was performing really nice, with averages near the 550 GH/s on Bitminter, sometimes even reaching the 600 GH/s

After the firmware update yesterday it has been hashing all day in the 400's range. I'm reading very good feedback about the new firmware, but whatever it was, it really screwed my hashing rates.

Anyone experiencing a similar situation?

Thank you in advance for your feedback,

Best,

I updated by "bad" jupiter from 0.95 (with enable cores) to 0.97 about 12 hours ago

The WU increased from 69xx to 76xx-78xx, but the error rate is high 37% and the cgminer Avg is the same, despite the increased WU
 (5s):504.3G (avg):482.4Gh/s | A:2669800  R:20300  HW:1004701  WU:7644.5/m

The pool reported speed remains lower on 0.97, currently 405.04Gh/s

[CMMPro]

0.97 on my Saturn has brought me up to 282gh and 4100 wu/m.

At a 3.4% HW error rate as well!

Quite happy I updated!

I have yet to see the flushwork occur hopefully it is recovering much faster now.

[ImI]

DHL literally dropped mine off about an hour ago.. up and running now on .97 (Jupiter)

I'm sitting around ~500GH/s - hopefully it creeps up after some burn-in   

Hoping my other 4 arrive soon!

when did you order/pay?

Using the web interface?

Or did you go in with ssh and fiddle with the cgminer timeouts and such?

(I have only been using the web interface as the ssh does not seem to like the username/password the web interface shipped with.)

It is coming at 2 days 400 diff

At a month Jupiter will be like jalapeño 0.30 per day

[kronut]

Looks like Hashfast is going to be a month late, which works to our advantage. Hopefully after this increase this will mean at least one difficulty increase that will be minor.

0.97 works great, getting 278gh/s avg on a Saturn, awesome!

Holy, after an hour or two it is up to 286-7 steady at 4100 wu!
(And 2.2% errors now.)

Seems like the errors were all at the start and now it isn't generating nearly as many...interesting behaviour.

I didn't do anything out of the ordinary - just configured it via the web UI, as always.

It has slowed down some over time though...  Looks like I am getting a sustained 245 GH/s at the moment.  WU is still high at 4136.

Hey - just as an update to earlier ...

Ended up getting a Coolermaster Silent Pro 1000w to replace the XFX Pro 1050w Black.

Popped in the exact same paperclip and it worked first try - been hashing at 554 stable for 4-5 hours now.

So, O'rama, I dunno .... maybe it was just that supply, or maybe it's an XFX thing, but I couldn't paperclip trick that particular supply.

Guy at the store had a thermaltake power supply tester, and it was giving all the right numbers on that, so ... I dunno.

That was my experience anyway.

Tried that XFX a few more times, jiggling the clip, jamming it in, just plain monkeying with it ... and I could never get it to spin up.

And again, thanks to the forum members for chipping in with the advice earlier. Nice to know it wasn't just me being puzzled.

jala makes 0.3 a day? dont think so.
