I understand this but there is one problem - in original CPU miner from Neisklar (https://github.com/Neisklar/quarkcoin-cpuminer) I am pretty sure diff1 is set the same as sha256 and it is used by thousands of users...

However I set up a separate stratum port (once again) for GPU users on Securecoin pool. As I dont have any GPU rig now could anyone test it for a while and post results?
