In typical KNCminer fashion the news release for the Titan has changed.
" We'll produce, test, assemble and ship Titans continuously from the beginning of next week, but yield success will affect the speed of deliveries."
Has been changed to:
"We'll produce, test, assemble and ship Titans continuously from next week, but yield success will affect the speed of deliveries."
So shipping of the Titan will start at the earliest this Friday or maybe with typical loose interpretation required with KNC announcements the week after.

I almost hate to ask you guys who got a Neptune this question....but
being a Titan batch one order (ok enough booing already!)
If you know or can remember how long did it take to from the announcement they had a 'chip"
to actually get a number of working neptunes out in a reasonable manner
I assume folks here know this from the obsessive nature of such an announcement of such
a chip arriving and the waiting on pins/needles so see something come off the production
line in a lively manner
hey I too need something to obsess about when they announce they have a 'chip' for the Titan
from what I remember it was NOT a speedy process in the 1st batch Neptunes case
anyway off hand if anyone knows let me know ...with no refund on the Titan ..need
to mentally prepare myself for more KNC slippage down the customer satisfaction scale so to speak
thanks hopefully you guys are pulling away on ROI with the low diff changes recently (knock wood)

They announced that the wafer had left the fab on June 2nd. I'm not sure of the date of first shipment but, about 3 1/2 weeks later. There has not been an announcement on the Titan wafer but, as you know with KNCs communication skills it doesn't mean a thing. If the wafer has not left the fab the earliest we can now hope for is end of August.
Even by their twisted interpretation of the wording KfC still delivered all of batch one ($13k) late without offering free hashing as promised; some of them have been very late. If KfC now tag batch two right on the end of batch one it effectively punishes batch one customers (to the tune of $3,000) for having a little faith in KnC and ordering Neptune as soon as they were open to the public.
It's just not right. I would be very happy for batch two and batch three to ship this week but KnC need to acknowledge that they were late and as such they need to lump all the batches together in one big batch for continuous shipping. Now that all the batches have become one big late batch they need to sort out compensation for the people who paid more. How can they justify the last guy in batch one not paying the same as the first guy in batch two?
I could understand if the last guy in batch one got $3,000 refund and everybody else got it pro-rata; so where "n=umber of days between delivery and start of batch two" it would be $3,000 - (0.1BTC * n) refunded to each batch one customer. That wouldn't provide any incentive for being in an earlier batch but at least the faithful wouldn't be worse off.

I agree with you a refund for those batch one customers of some sort is in order. I just hope KNC doesn't hold off a month thereby screwing the batch two customers. And by default screwing every customer who is waiting for their bonus miner.
Any batch 2 (10.000$ miner), in progress or shipped ?
There had better not be! They have to leave a month after batch one don't they?
Either that or send me $3,000 right about now.
Well since the bonus Neptunes ship after batch two you either want to wait an extra month to double your hash rate or picked a Titan. Personally I want all the batch two to ship immediately so I can double my hash rate. It's not like the second batch is going to have a large impact on difficulty. At least not relative to double the hash rate.
I'm amazed by the people who want to wait longer for the bonus just so another group of people can be screwed a little longer. The Neptune is late for everyone.
Considering some of your VRMs were over 100 degrees (based on pictures you posted earlier). I think you could safely say you achieved as high as 30 degree reduction on some VRMs. I think the VRMs and the fact that they are they are the BMR4641002 (max 40A) instead of the BMR4641008 (max 50A) as you mentioned earlier are the most disappointing aspect of the current design (KNC that's not a criticism; but a critique). I do understand that KNCminer was under a lot of pressure to ship before the end of the month. I wonder if they were expecting far greater power savings and that is why the board does not have the 1008s.
I think delivery dates written in stone are a two edged sword. They give targets to be achieved; but, can result in shipping before every important detail is fully dealt with. Hopefully we'll see revised boards coming.
I agree: KnC should have used more robust VRM's.
And indeed I had 107 degrees with some of the slot-1 VRM's due to a gap between pad and VRM... see this picture:
The edges of the aluminium indicate they use a mechanical shear to cut the plate. At least if memory serves me right it's been over 30 years since I used a shear. It's brute force and tends to twist the aluminium plate.
And this is the result: 20 degrees lower on the VRM's :

Newer homes built in the US are more efficient and don't require amperage like the in the past. That's why you see 100 AMP service for a normal size 3 bedroom 2 bath house now. My house was built in the year 2000, which is considered new in the housing world and came with 100amp service. If the house was 20 years old, I bet it would have 200-300 amp panel in the basement.
FWIW I have never seen a 300A panel in a home. 200A is the highest I've come across and that's usually in McMansions. Standard is 100A, and I've seen much, much older homes at 60A.
5 Neptunes would Max-out 100 amp service right there
Some of us installed 200 amp months ago.... Then, lightning struck... literally
That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.
100A x 240V = 24000W
or
100A x 120V + 100A x120V = 24000W
Same power...two phases.
Yes: I'm already working on this. Many things can be improved.
Thank you for you postings Elenelen. I've already ordered these because of your postings:

Conveniently these come with thermal tape already applied although I think thermal glue might be the better option. They are a little large; but, that can't hurt.
It is possible that KNC has a better solution; but, obviously they are under pressure to get everything shipped right now.
Here is a datasheet for a typical remote diode temperature management/fan control IC.
http://www.ti.com/lit/ds/symlink/lm96063.pdf
Note: "The LM96063 is remote diode temperature sensors with integrated fan control that includes remote diode sensing. The LM96063 accurately measures: (1) its own temperature and (2) the temperature of a diode- connected transistor, such as a 2N3904, or a thermal diode commonly found on Computer Processors, Graphics Processor Units (GPU) and other ASIC's."
These type of devices typically integrate with an on die thermal diode.
On the issue of BRM46x thermal design constraints, the spec says 125 C. Not 100 C, not 105 C. Looking at the data sheet, it looks like the device temperature is reported via the PMBus and may also be subject to configuration via a configuration file:
"This product is designed with a digital control circuit. The control circuit uses a configuration file which determines the functionality and performance of the product. The Electrical Specification table shows parameter values of functionality and performance with the default configuration file, unless otherwise specified. The default configuration file is designed to fit most application needs with focus on high efficiency. If different characteristics are required it is possible to change the configuration file to optimize certain performance characteristics. Note that current sharing operation requires changed configuration file. See application notes AN307 for further information."
Is anyone having problems with Neptune's shutting down due to thermal issues or is this yet more FUD being spread by haters and envious ne'er do wells towards KNC ?

Thanks for the information on the LM96063 and pointing out facts throughout this thread. I work with equipment where I can measure temperatures 100s of yards away so I don't understand why anyone would thing a small IC on the side of a board is not capable of reading temperatures directly inside an ASIC several inches away. The more I investigate and sift through the postings of people who don't really know the more comfortable I am feeling with the Neptune.
I have no doubt that a better heat sinking arrangement for the VRMs is in the works or could be made. At the least it's an easy thing to modify and I'll get my 12 year old (because of smaller fingers and better eyes) to take care of it for me. Based on the specs I would like to see temperatures maintained below 100 and preferably 80 to 90 degrees C on the hottest VRM.
Looking at the picture of the ASIC board

Curious that the manufacturer states that only up to 7 of these can be used in parallel.
Looking forward to hearing more details.

5%-- I didnt notice this before?
Hello do you have any information on what percentage of that is actually hosted miners? What I'm wondering is how much of that represents KNC mining as a company and how much of it represents the hosted miners for their clients. For example if one half of it represents hosting for clients then KNC hasn't nearly approached the 5 percent as a company.
Just curious about the facts here.
Re: [ANN][DRK] DarkCoin | First Anonymous Coin | First X11 | First DGW | ASIC Resistant
Just curious about mining Darkcoin in Windows environment. Basically the speed of hashing for GPUs. I'm finding my hashrate is considerably lower then those posted by many. Is there a difference in hashrates for a particular GPU in the windows vs the linux environment.
Thanks.
Thanks.
Re: Bottlecaps v1.5.2 Just Released Checkpoint Node New Wallet Design! Please Update
This isn't working. Could you please set it up on a decent website like mega and put all files in one archive? Be professional ffs...
Did you just go under file and select download all?
I talked to a guy with a farm that has over 200 GPUs. He supports this. It scares him that a little guy can buy an ASIC device and blow him away in hashing power. Much investment so little hashing.
Well the approach is different. Instead of just cloning litecoin like the many others you just try to steal the right to develop the coin. No wonder your an anonymous group.
