You'll be lucky to get stable at or above 1200 on the core with that card (I have the same Blue PCB). I assume the stock voltage is 1.256v. The memory as Huzzug said doesn't really benefit as it has enough bandwidth already also the memory on that specific card is at 1.5v whereas most other 7970's are at 1.6v, the memory won't go above 1600MHz regardless of voltage.
I'm currently running 1150MHz on the core at stock voltage which is incredibly high (1.256v) and 1500Mhz on the memory.
If you want to give memory voltage tweaking a try then visit the "AMD How To Thread" http://www.overclock.net/t/1265543/the-amd-how-to-thread/0_20
Download the "4.4.0b Modded Trixx" that will allow you to modify the memory voltage in addition to the core voltage. Trixx 4.6.0 has been released but it has no useful features over the 4.4.0 and it has not been modded yet and therefore cannot modify the memory voltage.

The VRM's do get a little toasty on this card especially in Battlefield 3, They are rated for 105c but its not recommended to run them over 85c for an extended period of time. The core stays cool though, never goes above 65c in any game, benchmark etc. However I'm using a Custom profile.Edited by Razor 116 - 2/20/13 at 6:59am
