FPGA!!!

[Wilson]

Tell me soon if you need one!
Btw your previous quote was 6months old and the other was a month ago!
A lot can happen in a day you know! And this is launched max a week back!

that calculation applies if I have only 1 Board, I have 5, and 5% investment recovered is my ROI over 5 boards

Its percentages, Its the same if you have any number of boards.

not really, your calculation was based on if 1 board was 1 Ghash, while only 2 of mine report that, its natural that the other boards pull down the %

its like marks at school/college,

for eg,
you get,
100 in 2 subjects and 40 in the rest subjects

your average naturally gets pulled down

anyways, my plan is set, mine how much ever possible with these boards and then sell and buy Jalapenos once they're out, and anyways, 26 watts power usage per board will not affect me in anyway, it's lesser than running a light bulb and a bit more than a CFL bulb

I save much more mining with these than my GPUs

EDIT:
consider this as "stepping" stone hardware, mine with them to save on power bill and still get $$ and sell them later on and buy a ASIC, as if not for BTC mining, the FPGA can be used for a variety of other things hence the reason they can be resold easily

may be somebody discovered a way to run 1 FPGA chip @ 500 Mhps(Since two chips give 1Ghps).

it is possible, there is 1 FPGA chip which runs at 600 Mhash/sec (600 Mhz freq) but the issue is getting those chips :/ they are very very expensive if bought in small quandities, only more than 10,000 orders get good quotes for those chips, hence the reason why we have to adjust with these chips until we get cheaper ASICs out

[Dashing]

and also it depends on the speed grade of the chip, different grades give different speeds and different number of stales and less/more heat

[rezurect]

Its higher than 400 Mhps in total , how much i dont know?
Wilson: Post a pic without the fan , top view  close up.

edit:
Black arrow suggests a Lancelot reaches a total of 500Mhps on May 17,

I think that with v42 firmware Lancelot reaches 500Mega hases. I haven't looked at your code but I think that based on the proof of work you should be able to accurately calculate the speed. You should not rely on how fast the device returns data but on what date it is actually returning.
Regards!

I have no idea if he made a newer version after May 17, He hasn't posted it.

[Wilson]

Sorry! All mine are customized! And i can't reveal them!
May be yea! I can of my sample piece!

[Wilson]

I know he hasn't posted it! That is the reason you will get it soon!
Else we ll have to wait!

[rezurect]

Customised FPGA.
1 Avalon ASIC chip hashes at 382Mhps, while 1 FPGA chip hashes at 500 Mhps?

It is running so i am not removing the fan and clicking a pic!

[Wilson]

I have sent you a pic and dashing himself has updated you with the screenshot and information!
So i am not going to convince you any more!
Just let me know if you want to buy it!
I can't do more than that!

maybe I'm missing somethgin, but on their web site http://www.cardreaderfactory.com/shop/lancelot.html
it is Speed: 400 Megahashes/sec.

so it s 300 usd  for Speed: 400 Megahashes/sec  only make sense if you buy 2-3 boards to keep it a toys, or much better revers engineer is produce locally.

price wise compared to ASICminer blades it is no good buy. to match one ASIC blade you need  32 Lancelot 300X32 = 9600 usd
ASICminer blade cost 50btc =  6500 usd, and no wait at all.

unless is there some official confirmation of 1ghs rate.

According to Blackarrow, a hashrate improvement to 500Mhps came from the firmware version. ie v42
The v42 also causes a reporting error which causes the speed to be reported as 1Ghps.

Although not perfect: an easy verification would be from the Web UI of the pool which shows accepted share number and speed,(btcguild or some pools report approx speed based on shares accepted) but you have run it for a few hours in the pool.

Again,
If this is directed towards me, I really don't care, I needed the FPGA, Wilson got it for me, I can see the difference in number of shares going per minute from the upgraded board and the other boards

WRONG ! the WebUI of a POOL WILL NEVER know your actual hashrate !!!! IT'S A ESTIMATED NUMBER ! even if you mine for a few hours, a sudden influx of shares will spike your hash rate ! So that is completely unreliable way to judge !

[rezurect]

true true,

since im saying its a firmware reporting error,hence cgminer is erring, other than a web UI i cant figure out how to look at the speed.
The formula works,after the U values converge in cgminer, but i dont think youll want to waste your time doing that,

Its not perfect ,I know it has errors, but i see no other ways to look at speed, the longer you run the miner the more accurate it usually gets, it averages out over time usually.
just help us verify speed if you can via a screenshot of a pool Dashboard after running a few hours, with shares accepted, else it would be skewed due to time.
