There are 8 main islands here in Hawaii,  But  technically 137 total islands in the Hawaiian chain.

Just saying.

Oh well, I guess I'll pry myself away from the computers
and do some actual labor around the farm today.....
Things are beginning to look like I abandoned
the place.... lol  


BTW:
Cointerra is saying mid February for Batch 1 Tear-the-money-from-your-wallet-Miner...!
Hashfast is sayin' Mid December for Batch 1 Baby Jetgusher...!
I don't feel any others are even worth mentioning....lol
Looks as if both CT & HF are taking March orders now....
and HF is asking the same price for a March unit,as they charged for a December unit....  OMG
Those Guys in So-Cal are smoking some good stuff...  lol
GO KNC!

Farm huh?  Maui Waui?  

And who's in SoCal?  Cointerra is in Austin and HashFast is in Silicon Valley.

okay, silicon valley...
...and no, I'm on the actual Island of Hawaii, not Maui...
although the State is also called Hawaii....  we have 7 islands

BTW... what is this?...poke Ewok hour?  

Anyone else notice NMC went to $2.50... !

Staying on the present topic, I'd love to live in Hawaii.  My father was a Seabee stationed there in WWII.  End of the war there were huge stores of partly assembled motorcycles, jeeps, cranes, trucks, all in cosmolene, that to prevent an adverse impact on post-war industry on the mainland, were laid to rest in large excavations and covered over.  They should be perfectly preserved in the cosmolene.

GET RICH QUICK SCHEME: 1) find the valley in which the machines were buried, 2) buy the valley with bitcoins you mined with your Jupiters, 3) request the EPA declare the valley toxic due to the cosmolene, 4) dig up the machines financed with some envirnmental disaster fund.

Capitalising on the fact that I saw that dud cores are better disabled, here's an experimental binary that tunes things fairly aggressively:

http://ck.kolivas.org/apps/cgminer/kncminer/cgminer

First it enables all cores on startup (so it can take a while before it starts mining!)
Then it will disable cores after only 3 hw errors in a row, but staggers disabling of cores 5 seconds apart.
Then it tries re-enabling cores after only another minute, but staggers re-enabling them.
If the cores fail 3 times in a row, they're decommissioned at that point.

Awesome. Thanks, ckolivas.

I'll fire it up now and report back my results after it has a chance to stabilize.

@bogart - do you have any close ups of the areas you advised checking for 'opens' around the VRMs??

That must have been another user...

                     maybe it got so hot as to melt solder and create an open.

That's would be what I would look for.

Use a flashlight and a magnifier and check the big power-carrying solder joints for hairline "cracks".  You can try push/pulling on the VRM too and looking for movement of the pin in the solder pool.

I used to see this all the time in old TVs and monitors and such.

Oh...yeah I guess I hadn't really looked at it when I said that.  I was picturing through-hole components, which these are not.

I guess you can't really see the solder joints on these so that wouldn't work.  Sorry.

just to inform u that there is something going on with Nov. batch...  



my Status (ordernumber 85xx) has changed from 'payed' to 'in progress'!

My order still just shows "paid" order 93xx

[Phoenix1969]

To maximise the performance of your November shipment orders, we recommend the following:
- for November Jupiter’s a 1200 Watt PSU with a minimum of four separate PCI-E adaptors (6 pins or 6+2 pin).
- for November Saturn’s an 850 Watt PSU with a minimum of two separate PCI-E adaptors (6 pins or 6+2 pin).

I might have missed it due to the noise level here but does this mean that the November Jupiter's are less efficient than their October counterparts?  I thought they were around 1W/GH

if memory serves 'orama said 650+GH/s and that the max consumption measured at the wall during test was 1050W.

so yes the worst case scenario is 1.6W/GHs.

Thanks guys.  That is a little disheartening.  Efficiency is really going to be key going forward.  Midsize miners will need lots of hashrate with minimal electric use to stay competitive.

I think it's just that the November batch is capable of being pushed harder (higher clockspeed, higher voltage, lower efficiency) using the forthcoming tuning suite.  If you wanted you could tune it back down to have performance and efficiency similar to what the October batch is running now..

I imagine most miners will run theirs as hard as they can in the near term.

KNC also did mention the November units would fit the "Underpromise, Overdeliver" scenario they like to employ... So given that they said 650 GH/s, and want you to get a 1200watt supply....  It could very well be that they normally push a bit more than 650, and that the Tuning Suite could even push them farther...    just sayin'...

[jxz]

As for my earlier post, im not 100% sure what it means, presumably a number of things.

It was indeed stated that the Nov rigs are to be expected to hash at 650Gh/s or more, but 1200w...

the 'recommended''inclined to go for' silent pro gold 1200w only has 2 PCI-e ports while the not powerful enough v1000 has 4 ports...

https://bitcointalk.org/index.php?topic=170332.msg3613013#msg3613013

The silent pro gold 1200w has 4 separate PCI-e connectors.

Seems like API is disabled in this version with the following message:
Invalid command
cgminer 3.8.2

Was it done on purpose? Can we get it back, please?

That's probably a temporary thing 'till the memory leak is isolated Ckilovas is working on.  It most likely stops the leak.  But I could be wrong.....

My order still just shows "paid" order 93xx

so next week + 2 PH? Interesting..

I am scared. Will November customers please show respect to us October customers and not start hashing for a while once you get your units.

[Xian01]

Hard day. KNCminer Water cooling upgrade.
Just photo.
May the Force be with you

 Very nice work ! Are you noticing any improvement with your hash-rate running them cooler like that ?

 Really looking forward to ordering a couple of these units when they become available again. Having a blast tuning/tinkering the Bitfury rigs, and looking forward to tinkering with KNC devices.

No, back then I meant KNC should help those newbie miners who are being introduced to bitcoin with Erupters by delaying November orders. I am a Saturn October customer (then upgraded to 5-unit machine). I also did a preorder of November, but was dumb enough to cancel it. So the only way for me not to feel too bad about this cancellation is if November units are delayed

Thanks guys.  That is a little disheartening.  Efficiency is really going to be key going forward.  Midsize miners will need lots of hashrate with minimal electric use to stay competitive.

no it is meaningless here.

I did the math in another thread but if it costs $100 electricity to run 2 jupiters and right now 2 jupiters will get you about ~25 BTC the next 30 days it doesn't matter if that power bill is $50, $100 or $300 compared to 25x$800=$20,000

so perhaps you could save $50 per month the next 6 months with some other lower power cost (vaporware) miner?  $300 over 6 months vs $XXX,XXX

Just make sure you keep your KNC miners running as close to 24/7 and all chips hashing as much as possible and enjoy the extra heat if it is winter in your area

I got an attack of the network lags after upgrading to 0.99  

Downgrading didn't help, powering down, restarting and rebooting didn't help. Even with cgminer not running ping times can take up to 2 seconds. SSH'ing in is excruciatingly slow. One time I couldn't even ssh in until I restarted it again. I just barely got it mining again. I saw others had gremlins that went away, but I can't seem to find any way to repair it.

I would try a different ethernet cable and/or switch.

I have a 4th module that was working a couple days ago, that now refuses to kick on. I haven't tried heating up much and have tried alternating ports and running enablecores and still nothing. Warming it up is my next option but does anyone have a proven method on getting a Die to come back? I had 2 not detected and managed to find ports where 3 'liked' being plugged into. But I have not eliminated all the combinations yet because I don't know if I should be power cycling these so frequently.

Flashing to 0.91 worked to get it to detect all 4 cores at one point, but haven't had luck since.

Have you checked the power cable or tried a different one?

You mean the blue PCI-E cable? I tried connecting it to different PCI-E connections with my PSU (1050W XFX Gold) I have tried different ports and still nothing. I will try to get it a little warm next.

I mean change the blue cable itself for another one, or remove the blue cable altogether and plug the PS cable directly into the module.

good work..  I suggested something similar eons ago but way before they gave up the keys to the code castle

hopefully the tuning application they are working on will have this ability in it as well (configurable)
this will allow our miners to stay more consistent than the crazy fluctuation

[DPoS]

Go back to 0.98.1, it's more reliable for many. Most people abandonded 0.99 as a lame duck.

98.1 beta seems to be the best in my book.. I run that on both of my 5 board Neptunes (or whatever we want to call them)

the newer cgminers are starting to have better features though, so hopefully we will be able to take those and run them on 98.1 beta  (unless there are some new files in .99 that I needs that I am not aware of)
