So, I have been using CDM 7.2 for about 5 days now on my W7 system. I was finally able to reduce my wattage pull through Wattman setting (and disabling dual mining), but am still stuck on a paltry 20.75 Mh/s on ETH per each of my MSI RX 470's.  I have tried everything on the CDM side, such as setting ETH intensity to the max of 16 in my command line, adding in all 5 of the recommended setx lines, set my virtual memory to 24GB, etc. None of this moved the needle at all.

So, I am now trying the overclocking route before getting into modding the bios on these.  A few things are perplexing though. In my Wattman, each of the 4 GPU's can only be increased from 1650 default to 1700.  These seems like a very low limit to me and setting all 4 to 1700 had zero impact.

So, using Afterburner, it actually gave me the option to raise Memory Clock all the way to 2100.  I only tried 1850 and applied to all 4 GPUs but yet again, absolutely NO impact... all 4 still mining at exactly 20.75. So, my question is, am I doing something wrong?  Shouldn't raising the the clock speed on these yield at least a 5-10% bump in mining hash-rate?  Or am I completely off base here?

I know of many people using these cards that have achieved 23+ right out of the box, so still trying to figure out why I cannot get close to that mark.
