I'm running 622khash/sec on my sapphire 4L 7950's:

7950 is 630kh+ even when undervolted
what is your configuration for that 630kh ?? how much did you undervolted it?
1050mhz core 1250mhz ram 1.050v 630kh+

I get 400 MHash from 5870's but only 250 KHash, so GPUs seems really bad for me for scrypt mining, the myth that they do as many kilohashes mining litecoins as they do megahashes mining bitcoins is just a myth to me so far, and I would much rather buy FPGAs than try windows to see whether it is true that windows gets better kilihashes than linux does.

not a myth, pseudo fact. windows will get you higher rates but that will be punctuated with just as many crashes.
Thread in sig.
update?

I get 400 kh/s scrypt on my 5870's and like 380mh/s sha... Stock speed across the board. Strange.

In Australia I am paying ~AU$0.28/kWh and therefore any FPGA development puts me on par with cheap arse elec costs in other parts of the world...so please develop some
Holy crap and I thought paying $0.16/kWh was expensive.
How do you survive on those crazy rates?
lol you'll be better off buying solar panels
I'd imagine his dollars are AUD, not USD.

Updates are on the thread in my signature. I will tend to update there more often since it is the ltc forum.

I'm assuming a scrypt FPGA could mine any scrypt coin not just LTC, like you can mine any sha256 coin with sha256 miners?
You do have the right of it, and thanks for the support guys on here. If any of you decide to make your own fpga, let me know I dont mind helping. We really need to secure the network further before all the goodies get released in the coming months.

6. makes me wonder why a Corp like ATI or even Nvidia owners (or a 100 others) have not cottoned onto a PCIe device as of yet?
strange free market capitalism quirk.
How many units do you think would sell compared to video cards? 1%? 5%? Costs of R&D for a big corporation are 1 or 2 orders of magnitude higher than for a small one because they want their product to work in 99.999% of the use cases rather than 99%.
depends on the build cost production ratio , how many other electrical devices get created compared to video cards?
it is not a video card market is it.
there is a reason there is no device right now , but that could be related to market information, again the market decides that .
This is more than likely the beginnings of a scam.
I base this on nothing but gut instinct, but I've read this whole post. I also clicked on janislee's name and read what he's posted elsewhere.
He seems nothing but sincere, and intent on being more professional than BFL. Anytime someone posts something that sounds even remotely serious about following through on a LTC FPGA he's right there offering all manner of technical input to the OP.
I think I'm in.
I completely agree. I may not see the current value in having the fpgas now at this moderate effeciency, but I trust janislee and know that fpgas are the next step, even if only in better securing the network for lower power usage.
