hey mate,
I currently have a Dell PC with 1GB of 4200 DDR2 RAM and i want to upgrade to 2GB
current RAM , pc 4200, 240pin, clock speed 533mhz
GeIL 1GB (2x512MB) PC5300 667MHz Value DDR2 Dual Channel Kit (GX21GB5300DC
RAM wanted pc5300, 240pin, clock speed 667mhz
Now when buying RAM you:
a) check your motherboard to see if it will support the RAM
b) check the number of pins i.e. 184pin, 240pin
c) check the clock speed in this case YOUR RAM: pc 4200 533mhz Geil: pc5300 667mhz
If you purchase the GEIL RAM it will fit into your motherboard but:
a) the geil RAM runs at pc5300 667mhz (faster then your current RAM) your RAM runs at pc4200 533hz....therefore the GEIL RAM will run at the speed of the current stick pc4200 533mhz ............
b) some motherboards do not like memory to be mixed and this could causing errors such as a) system restarting b) your new RAM not being found altogether
therefore what you need is to find out:
a) the speed of RAM your motherboard supports i.e. pc5300 667mhz, pc 6400 800mhz or pc8000 1000mhz....
b) think whether you want to sell or get rid of your current PC4200 RAM stick and upgrade to slightly faster speed ( i dont see you seeing much of a diff well depends on how fast the RAM like if its pc 6400 or pc 8000)
c) just purchase a 240pin pc4200 RAM stick...(if this option find out the manufacturer of the your current stick so you can get the same make and model of RAM you currently have)
in short the answer to your question is that if you buy the geil it will run at the slower speed of pc4200 and may not even work at all...dell machines grrrr
therefore i advise to either upgrade RAM altogether so long as your motherboard supports faster RAM or just buy another 1 x pc4200 240pin stick same make as you already have...
sorry about the essay but at least you know how to buy RAM now
