I did tell you guys about results being "skewed by time".
No matter how many times you recompile cgminer, the error will stay till the devs fix it.

I don't recall that, you kept asking for proof on top of proof for the miners, anyways I may have missed that in last nights shit storm

Proof on top of proof because i was saying that your proof of cgminer is a reporting error. Hence you need something else to prove it.
U value converges = Run for hours , you dint have time apparently.
I say the pool results could be skewed due to time, the same apples for cgminer.
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.

Err, I have these boards running for over a week now :/

anyways, matter is solved, its a display bug.

@rezurect : oh just remembered, you missed my question earlier, did you get your 150 Ghash ASICminer which you were offering to Wilson??

See...
I am not forcing anyone to buy this! I am tiered of convincing people. Those who believe may! No competition...
I have posted what i have seen.
I am not going to convince any more people!
I have made this post based on Dashing's miner performance! And what i saw was each board was at 998mhash and 1.02ghash. Avg of 994mhash. I think that's good enough and worth, as the shipping is within 20 days.
Atleast we all know that we as going to get a minimum of 800mhash each board as they 2X chips are used!
So you order 10 of them, you can be sure of getting a minimum of 9ghash as Kano said but according to Dashing, you will actually be getting the other 1ghash too!
I posted what i saw! Sounded pretty good as FPGAs can be resold once they get outdated unlike the ASICs as they are application specific!
So its up to you guyz to decide to buy or not to. I have already received a bulk order.
Anyone still interested, just PM me!


Cheers,
Wilson

It's either stupidity or a scam - absolutely nothing else - either way it doesn't matter.
It's not 1GH/s and most likely 500MH/s at the most if he's using the v42 bitstream.

Wilson you need to drop that stupidity I've already told you it is wrong - continuing to claim it's correct is indeed a SCAM.

It's also not a cgminer bug, it's to do with the settings used or the default settings.
My Icarus code handles all sorts of Icarus bitstream devices with the correct settings, and those settings options are there to change the way it calculates the work done and also to change the timing it uses to send work to the device to avoid it running out of work and being idle.
The Icarus driver default expects a device with 2 FPGAs, fixed frequency (380MH/s), and the bitstream halving the work in a specific way (which is what a standard Icarus does).
You need to use different options if the device is different to a standard Icarus
If it's different, the default options will get wrong values for MH/s since it counts hashes based on the settings.
If they are very wrong, the device will often fall idle and do nothing for short periods of time.

... and all this is documented in the FPGA-README that I wrote last year ...

HI Kano
I think all this because of the confusion I have cleared it here.......


Alright, just saw OP edits and will pass on my 1.5 c.

OP had not posted expected hashrate. I would assume that he added
Quote
Its approx 4btc @ 1ghash!
, after checking with his customer - Dashing.

Dashing is testing the equipment that he purchased and only vouching for what he can see, accompanied by screenshots. Seems very legit and Dashing's words show that he does honestly believe the hashrate he sees.

Kano's confirmation of the same overrides what Dashing's tests have proved, unless we are talking about some other FPGA which has been customized.

In this event, I would either request a demo unit to be sent to kano to test and send back.
Or, some actual specs that can be investigated by the community.

Hmm, i think this is what might have happened :/ I got the boards from Wilson (he never promised me 1 Ghash) and then was surprised to see the hash rate on the first 2 boards and told him about the hashrate, hence the reason why he probably offered it at 1 ghash

I never fudged/played with any stats,
I just use --ircrus-timing short as usual and nothing else, I don't know why its reporting that, i'll probably recompile cgminer agian from git Smiley

Except that the post of his quoted is still saying it's valid ...
and his last two posts haven't taken back that comment ...

specially this comment pissed me off too ... coz it's a lie ...

I am really sorry, if it has to be this way!
I just advertised the info given by Dashing... Thought it would help people out there expecting better hash at lesser price!

I take back all my posts as it was an error with the display!
Was misled buy the display error!
All your btc deposits have been refunded except for few who wanted me to substitute it with the 400mhash boards.
