Getting freq specs of gpu

Hello, log time no see.

I noticed my GPU box has the specs of a standard OC gpu and not the OC2 I purchased, I've tried PC Wizard but it says my gpu Memory Frequency is 850MHz vs 1700 that it should be, see what pc wizard says about it:

is there a program that will tell me the frequency specs of my gpu to make sure I havent been ripped off. My GPU says OC on the heatsink cover instead of OC2


Also, i checked my PCMark06 score of a OC2 vs mine and my card was rediciliously lower than specified here:

Thanks

 

Thats correct, 850x2 = 1700 DDR .

 

oh rite thank you very much so the ram is on dual channel
