I have a Dell GX520 optiplex model (mini tower), and I want to upgrade its RAM.
I currently have 1GB RAM and I want to upgrade to 2GB.
All I know about RAM is its capacity, and I've heard about speeds lately like 400MHz, 533MHz, 800MHz, 1333MHz.
I want to know what are the differences among them and can my PC support all those types of speeds or not? And what is the most suitable one for my Dell PC, to avoid any problems or limitations.
if i purchase ddr2 with higher speed like 800 or 1333 , it will cause any problem in the future or it doesnot work at all?and i think it will support till 4 G not 2 – Anyname Donotcare – 2011-01-04T09:36:38.200
@user higher speeds are unlikely to cause problems, but will not work faster than the motherboard's limit; as such the extra cost of getting the faster memory will be wasted. It might support more than 2GB; I simply performed a quick web search for that link which states
Two Memory slots offering up to 2GB
, it does not clarify if this is 2GB each or in total, but I read it as being in total. – DMA57361 – 2011-01-04T09:39:24.690@user checking the PDF, it states (for the GX520)
– DMA57361 – 2011-01-04T09:41:08.3732 DIMM slots Non-ECC dual channel shared DDR2 SDRAM system memory (400 and 533Mhz) up to 2GB
, so I'm fairly sure you are limited to 2GB in total.yeah ,, sorry u are right..i think this upgrade will increase the speed of my computer , if u recommend any type of RAM,or has any advice about my computer i will be grateful.thanks a lot.. – Anyname Donotcare – 2011-01-04T09:50:12.150
@user as said in my answer, the best you'll get out of that motherboard is using **two identical 1GB sticks of DDR2 533Mhz**. They should be exactly identical (ie, exactly the same size / make / speed / model / manufacturer) to ensure they will work dual channel (which you want them to). In fact, the safest best is probably to just buy a 2x1GB RAM "kit", to ensure they match. – DMA57361 – 2011-01-04T09:54:35.917
