I am planning on buying new memory/RAM for my computer. My computer currently has 2, 512 MB DDR2 chips inside.
HP Pavilion a1600n
AMD Athlon(tm) 64 X2 Dual Core Processor 3800+, MMX, 3DNow (2 CPUs), ~2.0GHz
Current Video Card:
NVIDIA GeForce 6150 LE
I am planning on buying a 1GB DDR2 RAM for my computer. Do the chips have to all be the same memory size? or can they be different for example: 2 512 MB and 1 1GB RAM. Also, what are some cheap, good quality RAM brands?
Whit this specific type of SDRAM - the DDR2 SDRAM - yes, it is.
But it doesn't mean it's compatible with all types of SDRAM. SDRAM contains many incompatible types of ram too. Actually any type of currently used RAM is SDRAM as much as I know, at least in consumer computing. Only some first level cashes are SRAM /Static RAM - contrary to Dynamic RAM/. SDRAM is a broad field.
