I am looking to up the RAM on my HP Pavillion A6000n desktop machine. Looking at CPU-Z, it seems as though the current memory in there is DDR2 PC2-4300 (266 MHz).
My question is, can I go with any DDR2 memory that I find? In other words, does it have to be PC2-4300 or can that vary?
Thanks in advance!
EDIT:
For instance, can this DDR2 PC2-6400 RAM work in my machine with no problems?
Answer
a DDR2 module will downclock in the event of inserting a higher-frequency DIMM than is supported. Also, if the clock speed of the DIMM exceeds the maximum supported frequency it will underclock accordingly.
If you're running in dual-channel mode, the RAM will run at the lower clock speed of the two DIMMS. (e.g. PC2-5300 & PC2-6400 = PC2-5300)
