Improved Ztex 1.15x bitstream (168-180MHz) will be available soon (max tomorrow).

not showing on pool rate and the WU/m are the same for both so it looks like a display bug nice find though 
Yup, as confirmed by the EU pool, this cgminer is seeing double -- the actual rate is pretty much half of the displayed one for 5870s. OTOH, the display is fine for 7970s.

this is my .config for the Asus EAH6950
now i have 1.55GH/s temp 58° C
now i have 1.55GH/s temp 58° C
I do about 1.45GH/s ~ 20 WU/s on the 6950 so will give it a try
thanks for sharing the conf its always worth tweaking
whit this setting ~ 23.2 WU/s
on your pool whit diff set to 1

One 5870 is 900,300 and another is 925,925. The memory speeds don't seem to matter, similarly to sha256, but the other card does not allow very low values.
I am running 920, 600 but only getting 1.25GH/s each only difference I can see is driver version any changes to the cgminer.conf?
My commandline only has
Code:
./cgminer --blake256 -o http://nanite:8772/ -u teknohog -p XXXXX -I 14
I have tried different worksizes like -w 128, and not seen much effect. This version of cgminer (kR105's 3.7.2 branch, latest from git) does not allow things like --thread-concurrency that I'm used to tweaking with other coins.
I guess I should try this on a pool that can report an effective hashrate, in case this cgminer shows it wrong. It's hard to get a good evaluation from a few day's solo mining.
Edit:

both my 5870s are showing about 2.5 Ghash/s each, while 7970s are a little slower than this, all in contrast to the commonly reported figures. These are with kR105's cgminer, SDK 2.9 and ati-drivers 13.12.
very strange, what core/mem clocks are you using for 5870 and 7970?
One 5870 is 900,300 and another is 925,925. The memory speeds don't seem to matter, similarly to sha256, but the other card does not allow very low values.
The 7970s were clocked to something like 1000,1500 but in fact they pretty well match the 2.2 GH/s from the main post - I probably confused them with the 7990 at first.

Many thanks to all developers here, it has been great to see a new hash algorithm take off, with all the different software and hardware support 
I've done a little solo mining on GPUs, and today I just found the Ztex 1.15x bitstream which is running great at 140 MHz. Unfortunately I don't have the ISE license for these FPGAs, but I'll try to do whatever testing I can anyway.

And my thanks to you too as I've used your code in both the blakecoin and litecoin FPGA miners. I hope its all been acknowledged fairly, but if not then just point out the missing attributions
It's fine, thanks
(Though to be precise, I've never worked with the LX150 -- my main contribution has been serial comms.) January 10, 2014, 10:16:44 AM

Great to hear from you teknohog your work is awesome, I have had many hours of fun playing with your code in quartus
even when you do have a licence for ISE it is such a pain to use and has many issues during map/par very hard to get consistent results
I have some 5870s but running ati-driver 11.11c will give 13.12 a go when I get some free time
any tips, help, advice, test results, bug reports are always welcome
Thanks to everyone who has waited or helped, Blakecoin has a second pool

My bet is on FPGA
Icarus = icaras ?
http://en.qi-hardware.com/wiki/Icarus
its all good though nice to see more miners regardless of their platform

Icarus/Lancelot is a little more tricky to use than the ztex or CM1. You need a Xilinx platform cable (kosher ones are expensive, but a DIY jobbie only costs a few dollars to build if you've got a parallel port on your PC), a huge software download and some patience to program the devices (either each time on powerup, or permanently via the MCS ROM). I've only just recently added support for the current bitstream to cgminer (its enabled via #define LANCELOT_52, so needs to be compiled in and will not then work with a CM1). I can provide a windows build if anyone is interested.
If it is an icarus farm then I'm very impressed. I'll just pop my tipjar address up BYEE2FvGv4L3yt5aEr8BQ73oWzXMu59Fwz in case he'd like to make a contribution (no need for anything upfront, a few percent of gross would be very agreeable
)I have the lancelot working on my pool with getwork and your python miner works great
edit:
I think kr105 also has working getwork on his pool port 8337?
kramble has done some really awesome work on the FPGA if you use his code consider a tip or two over time

same problem with wallet /(i have set UTC time in my rig).
UTC time zone is not the cure, wallet restart is.
That is why i am asking the automatic wallet restart as an implement feature of the wallet

starting a wallet is a schedulers job use the features of the OS
windows via scheduled tasks and a bat script or linux via cron jobs and a sh script
pseudo code:
blakecoind stop
wait
blakecoind
then just set a scheduled time to run the script
