its 3 better than 2 ???

Ok this my situation, I had 2 gigs of ram in my f3ka laptop and then I wanted to add another gig. for a total of 3 gigs right!!. Well the mem. rating score went from 5.9 with 2 gigs to 4.9 with the 3 gigs wtf. so my question is this: is 2 gigs better than 3 gigs or what??? to tell you the truth the laptop seems to run better with 2 gigs???
Another thing not related to this I instaled Vista's new sp1 and I had nothing but problems after wards so I uninstalled it but now my usb mouse and keyboard seems to draaaggg a bit (lot) anybody else has had anything like this happening to them, any body, hu, hu

 

Yea, sp1 has alot of sketchy results depending on different hardware and drivers. But Windows experience rating is jack. 3 gigs will run better than 2 gigs, unless your memory is now running at a slower rate (i,e you were running 667, but now running 533) But even then, its not much of a decrease.

 

How do you check to see at what speed is the ramm running??

 

cpu-z should, else SiSoft Sandra Lite (the free version) can also get this info.

 

WTF!!!!!!????? cpu-z reads the mem, 533 and not 667 like is supposed to, so what do I do now get dif. mem or what is this the end of the world chiken little?? live with it or do what?? any help anybody, I'm new at this HEEEELPPPP ( dang I forgot to breath again )

 

Things that can happen:

First you ram can only run as fast as the slowest stick installed so if you have 2gigs of DDR2 800 and then throw in some 533, it will make all of the ram run at 533.

Second, your cpu/ram may scale to save power on your system so to get a true check of everything make sure the system is under load, use something like wprime, 3dmark, ect to make the system work then check speeds.

Third, Memory score can go down adding more ram because with 2gigs in equal parts your system can run dual channel, its not a big boost, nothing you will even notice but a benchmark will show it. Putting a odd number of ram in there you will lose dual channel. There is a newer thing called asymetric dual channel wich is a slower version of dual channel for odd numbers of ram, not all systems can do this but it will still "rate" lower than a full out dual channel setup. 2 vs 3gb is not a huge deal unless you doing something that uses more than 2gb of ram. 2gb at a faster speed is better than 3 at a slower speed IMO, in a multi part benchmark the 2gb would win in most test, and the 3gb would only be better for the data capacity.

Fourth, the chipset on your computer may not support 3gb of ram at full speed... I didnt know laptops had chipsets like this (and maybe they dont) but I know for a fact some older desktops had chipsets/mobos that didnt handle alot of ram well and the trade off for having alot of ram was that it was forced to run it at a slower speed.

 

Well the thing is that I get 533 ghz. with 2 gigs. of ram so I just don't get it???
