GTX 1060 6gb x 6 Myriad-Groestl Pools hashrate problems.

Ok, I really dont understand what is happening recently with my rig... But heres my problem :

CCminer tell me Im mining at around 235 MHs after the tweak Ive done with msi afterburner.

When I had to swap my cards with my main pc, to valide at how much each cards can get their best ratio electricity/hashrate, Ive reinstalled my driver everytime I made a switch.

Now, find me how, but even if CCminer tell me im mining at around 235 mh, I can get only 80 to 100 mhs at suprnova and mining pool hub, and blockfactory give me 23 mh instead of 230...

Can someone here have some tip n tricks to help me ? Even on my main Pc with one GPU CCminer tell me Im mining at 48 mhs, but I only receive maximum 17 MH.

I really dont know what I should do now.

5 gpu rigs = 239 MHs ---> 38 Mh at pool
1 gpu pc = 48 MH      ---> 6 mh at pool

Seriously, I understand the 10-20% margin, but 80% ?!

I'll honestly send a tip of about 0.005 btc to the person who will assist me. Could pay up to 0.01 btc if its harder to fix than it should be.

I had a hashrate around 230 mh yesterday.

Thank you...

Now my effective hashrate of all my 6 gpus is of 33,85 MH/s instead of 275 MH/s
