The new version is working great after reworking my overclock. The oc I had been using with previous versions was causing the miner to crash. Reducing the oc managed to keep about the same rate while slightly increasing efficiency from about 3.3 Sol/W to about 3.5.

Keep up the good work.

What settings are you using and what card is it?
MSI Gaming X
+150 clock +610 mem 60% power
Efficiency is a little better at 60%, rate is closer to 510 Sol/s at 70% power.
What drivers are you using. My card is Gigabyte G1 and with this settings i get 470 sols max. Drivers 388.13.
Tnx
I'm using the same drivers. 388.13
Is it possible your card has a lower base speed?
Afterburner displays my memory as 4428MHz (+625) and GPU bounces around from 1848-1886MHz (+150) and voltage is around .889mV
