Hello Everyone, New To Upgrading PC's Therefor PLEASE Be Patient & Understanding If My Question Appears To Be That Asked By A Complete Novice. I have a standard mass produced Desktop PC which has 4Gb of RAM installed, 2 slots with 2Gb in each, And would like to know that if I were to double the capacity in Gb up to 8Gb, 4Gb in each slot, Would it be beneficial ? The reason why I ask is that the installed 4Gb is apparently the maximum that will be supported by the system. CPU is Intel Core 2 Quad And the OS is Windows Vista 32 Bit. If I would see no difference in RAM performance by replacing 2 x 2Gb with 2 x 4Gb would I see an increase in RAM Performance if I were to replace the fairly cheap RAM boards with higher quality RAM, Such as Corsair just as an example. I apologise if my questions are those of a complete idiot but I am trying to learn as much as possible about how to get the absolute very maximum with the system I have until I can afford to build my own Custom PC later this year. Thankyou In Advance For Any Replies To My Questions :~)
