ok it shows over 1900mb, and the speed drops to ~40-60 in the last 500

idk what app you're talking about.

D2ultima, win8.1x64, gpu-z 0.8.6 afaik 660ti is built by 1536+512 scheme, where 512 works through slower bus or something. My problem is that gpu-z never shows past 15xx numbers, so my question is do these extra 512 exist and work properly, while gpu-z just can't see it, or what; how can I check it? Here's the tool that I've used to load vram (but in games gpu-z doesn't show past 15xx vram usage neither): http://nvworld.ru/utilities/vmt/

my 660ti in gpu-z never shows above 15xx , does this mean that the last 512 are not unlocked or not working ? I've run a 'Video Memory stress Test' program to load the memory and forced it to use 1800mb, the program showed that it uses just above 1800mb but gpu-z was still showing 15xx numbers, while VMT haven't shown any memory problems..
