How much performance should increase if I double the RAM??
Posted on 2004-09-04
I have Toshiba Satellite P15 479, It came with 512 MB RAM 256 X 2 ( PC 2100 )
I purchased 1 GB PC 2700 and ran Sandra's Memory Bandwith Banchmark on the system. To my surprise insted of seeing significant increase in performance the performance was half than it was with the orignal configuration. I tried bunch of configuration after that ( 256MB , 512 MB, 1 GB, 1.25 GB ) and the best performance was the original configuration.
I concluded that since the RAM was from unknown manufacturer it was not performing as should.
Today I went to Fry's again and purchased 2 X 512 PC 2700 Kingston SO-DIMM and was expecting performance to go around double on the Sandra's graph....
It did go up but not quite as much as i had expected, It went up like 10% ....is that how its suppose to be? or am i missing something?
Is it worth to pay $120.00 for this kind of performance increase??
any guidance will be appreciated
