That's true!
The new one is just going amazing!
There are a lot of orders!
Lemme know if you were interested!
You got your proof from Dashing!
He himself has ordered a bulk from me!
So...

Good deal, yes
but 1ghps ,no
The utility U and WorkUtility  WU in cgminer tells the truth, thats why blackarrow is selling it as a 400Mhps FPGA.

Hello everybody!
.....................
.........

Err,
need to quote whole post = NO
 I dont know why his boards are submitting so less per minute, anyways,

Let me show you my screenshot if that helps you understand,


HAVE A LOOK AT THE NUMBER OF SHARES GETTING SUBMITTED PER MINUTE

If its a Lancelot made by blackarrow,
Blackarrow did offer an upgrade, if he started selling ASICs.
1Ghps is a cgminer display error according to the designer.
Apart from bogus speeds reported by cgminer (900Megahashes), it actually started yielding better results... It had quite a lot of dropped packets but more accepted packages than the other devices.

Guess which one is running v42 firmware ?
So if its a Lancelot its a 400 Mhps FPGA, after the firmware update.

not really, once you upgrade the firmware it submits more shares, but a few are stale, but if you're mining on a PPS pool that wont matter, also you can see blackarrows posts towards the end, he also proves that the hash rate reported matches the number of shares sent per minute

the best thing about this deal is the shipping cost is toooo less, Wilson has worked out a very good deal for the boards and is offering free power supply and is offering a legit deal, I have spoken to him for over an hour today and I have already bought 4 through him.

At least an hour.
The speed is of course an estimate, the A over a day or 2 will tell you if it is accurate.
However, 3 HW with 12 A is pretty bad too (20%)

Apart from bogus speeds reported by cgminer (900Megahashes), it actually started yielding better results... It had quite a lot of dropped packets but more accepted packages than the other devices.

Code:

Guess which one is running v42 firmware ?

However, if you look at the HW errors, it is indeed very high - almost 17%
I'd think that might mean it might shorten it's life?

Is there a way to clock that firmware down a little to get that HW number a lot lower?

Also the incorrect MH/s could be directly related to the firmware - the standard Icarus firmware divides the work in 2 on 2 FPGAs and runs at a constant MHz
I'm of course assuming that's what the standard Lancelot firmware does also and it seems to match that by reporting the MH/s correctly.
Do you know what that firmware does (and also do you have details about how to upload it? I have a jTag cable also that I have never used ...)
So if its a Lancelot its a 400 Mhps FPGA, after the firmware update.

Product name?
Lancelot?

not sure about that, btw how is your 150 ghash ASICminer ? I herd about that from someone..

another important thing Wilson mentioned is that,
these boards can be resold easily as they are FPGA (can be reprogrammed for other things unlike ASIC) and will be profitable for a long time with 24 watts power usage

Its approx 4btc @ 1ghash! Delivery within 20 days at the max!
Will return the change if i am left with any.
After 3 months, your boards can be upgraded!

Name of the Product?
No of the Chips onboard?
FPGA upgrade to what?
Nothing?

HI,
I had spoken to Wilson earlier today,

2 x Spartan6 FPGA
2 chips

FPGA -> ASIC or QuadFPGA (4 months or so)

Also, another thing about these boards you have to keep in mind is,
1. The hashrate reported on cgminer will be 400 Mhash unless you upgrade the firmware which fixes it to 1 Ghash, this is ONLY A DISPLAY / HASHRATE CALC error as cgminer estimates the hashrate and nothing else, the miner will submit about 6 - 7 shares per minute


Estimated time currently needed to reach 0.01 BTC ($1.35)    --> 844 Minutes(s)
Estimated time currently needed to reach 1 BTC ($134.75)   --> 55 Day(s)

Hey!
Bulk ordering FPGAs! PM me if interested!
ASAP!
Orders accepted with in 48hrs of this post!

Cheers,
Wilson

How much and what hashrate?

 [Moderator note: Do your own research before buying. He's selling x2 Spartan boards (Lancelots), which only can do 400~MH/s. The 1GH/s comes from a CGMiner display bug]
Cheers,
Wilson

[Moderator note 2: Kano, one of the CGMiner dev has confirmed that this is never gonna work]

I am confident as i have gotten the result! Not forcing anyone to buy!
You may pm me if you are interested!
This post will be out in next 24hrs!

Out in next 24hrs? You mean your gonna run with the money in 24hrs never to be seen again?

Right, so you either fudged the figures or didn't wait for the numbers to settle.
The run time shown is 2 minutes so the numbers mean NOTHING.

You cannot get 1GH/s out of a any pair of Spartans I have seen anywhere.
500MH/s is possible, 1000 is SCAM.

I wrote the software in the screen grab and I know how it works.
... looks like it's time to go visit that other thread also ...
