I have been offered a Geforce GT 640 2gb gfx card and have been trying to find articles on the net to try and determine whether this card will work in my system.
Although my computer is a HP pavillion a6455 it seems that the mobo it is using is a completely standard ASUS Narra 3,,,I say this as I have read that sometimes HP don't always use the standard mobo as they someitme alter it for what they want.,
I am hoping this card will work even if there is some chance of a bottleneck somewhere along the line and I am also going to go to the max 8gb of memory too,,,I want to do this so that I have got a slightly better system than what it is now that will be a stop-gap machine until i can afford to build a better system.
I understand that the memory modules are PC2 6400 667 or 800 Mhz, But I have also seen a few times that the mobo can be quite fussy with the memory and doesn't like anything except "Crucial" Memory upgrades,,,could this be true ??,,or is it more likely that it is just someones preference.
Also,,WOuld it matter whether I use DDR2 or DDR3 or can this make a difference. ?
I appreciate any help that you can give me on this matter.
Thanks in advance
I have also noticed that there were a few different a6455's but it seems to me that mine is the gb version,,I did notice that the italian one has got different proc and mobo which seemed strange,,,I only mentiuon this so that you can get the right one to look into to help me,..
