Same problem here.
Intel I7 - 740QM
Ati mobility 5870 1GB - 13.11 beta driver
6GB RAM
Windows 8 - 64 bits
Same thing.
i5 2500k
HD 6950 - 13.11 v8 driver
8gb RAM
Win 8.1 - x64
"Upgraded" from win 7 to 8.1 last night just for the extra fps. Was excited to see the 30+ bonus when I first started. Lasted a few hours before the first memory issue. Now I can't do two games in a row without having to exit the second game and restart my computer. Even tried that cleanmem fix in this thread and that didn't help either. Since it requires the name of the program I think it just cleans the current issue of bf4.exe and ignores the issue: the phantom RAM hog.
