This driver seems to be good for my card, temps seems fine after more than one hour of COD MW WZ SP campaign (this game does have oodles of cut scenes), my room's at a comfy 23C with my usual preset UV/Power Limit/fan setting....two things puzzle me: 1. Why is the memory clock showing this? Is this normal? 2. Why is Memory Used (Dedicated) so high? I mean 14.5 GB is kinda high, isn't it?
