Powerstrip, and videocard Memory overclocking?

[Liquid3D]

Hello all. I've been using Powerstrip on and off for about two years, and never fully appreciated it's potential, and the manner in which it interacts with the videocard. I've actually done a comparison among Coolbits, nVHardPage, Geforce Tweak Utility, RivaTuner, Rage3D, Radeonator, etc. (depending on whether I used my Geforce or Radeon cards) and I've found that Powerstrip seems to acheive consistantly higher scores, in almost every case. I've learned this is a result of the program's ability to directly affect timings on the videocard's memory, such as latency etc.

My question, or inquiry is to become more closely acquainted with Powerstrip's Adapter information sub-menu, under the Options menu. In the picture below one can see the boxes marked Memory addresses, IRQ, and Latency. Underneath these boxes is a large menu/box with many smaller "check boxes" with options including "Memory write-and-invalidate", "Responds to special cycles" and "User-definable-configurations-supported" just to name a few. Does anyone know of a tutorial, or have first hand knowledge of the effects produced by Enabling or Disabling certain options?

There may be answers to some of your Q's at: www.rojakpot.com/default.aspx?location=1 . Adrian Wong may know more about BIOS than just about anyone else.

His site deals with mainboard BIOS's, but some of the info may be transferable to Vidcards.

Thank you, I'll give'r a spin.
