Hi,
I just released an optimized version of sgminer for jackpotcoin for
14.6 amd drivers.
It was tested on my R9-290x at 1050MHz.
The hashrate is 5.97MHash/s
with the standard jackpotcoin miner, the speed was 3.5MHash/s on 13.12 drivers and 4.1MHash.s on 14.6.
So it is an increase between 50% and 100% depending on the drivers you currently use.
This is still lower than nvidia hashrate (however here it is running on all the hashes... so this is at that level still a work in progress
The source can be found here:

To use the algo:
sgminer --kernel jpc -o pool -u passwordDonation are welcomed to support development effort (and since you will be getting more coins) and they can be sent at these addresses:
JPC: JWdVcJZdmdTdFEM1acumNQjrnrx3J7mdec

A bounty from jackpotcoin dev would be good too

Nice work!

I saw your another tweaked sgminer in talkcoin thread.
Improved hashrate is almost same to that of talkcoin's one

Of course they are basically identical algo, right?
Now I'm just wondering that there is difference between NIST5 algo used in talkcoin and JHA of jackpotcoin.
I think only difference is hashing order (BLAKE, JH, Skein, ...)
If this is true, it seems that talkcoin is successor of jackpotcoin in algo perspective. (jackpotcoin was launched earlier)
In terms of individual algo they are the same (the 5 finalists of the nist contest) however the way they are used is different as in jpc it is keccak followed by three random rounds of groesl or skein and blake or JH.
(however the individual algo are found in many ex cpu only coin like quark, hvc, X11 etc... )
