Help! Stratum for Quark

[capslock1874]

I have build a quarkbased coin. it works fine with cpu miner, but the hashrate will get huge when you use sgminer with your GPU(like HD7950, it wilil get 400M/S, but it's not the real hashrate, they can't find any blocks.) So, the GPU miner will share the coins in pool, but finding few blocks. Can anyone help me solve this problem? Plz!
