I believe so but it'll downgrade to the lowest one.
One can purchase a 1gb pc2700 333mhz 200 pin ddr sodimm memory for their laptop from Best Buy. They carry the best and lowest prices around. Their prices are unbeatable.
DDR SDRAM memory modules can be installed at a 333MHz bus speed and operate at that speed. Specifically, DDR400 (PC3200) memory modules typically operate at 333MHz bus speed.
There is usually a panel on the bottom of the laptop. You unscrew the panel, pop out existing memory, and replace it with the new memory.
333MHz
It is a form, speed and type of memory.
333MHz
I have bought one 400mhz pc3200, it has a cut at a difference location on the stick. It wouldn't fit on my pc2700 333mhz slots on my laptop.
One can purchase 2GB DDR2 667MHz, at several online sites. Some of these online sites that carry this memory are "Amazon", "eBay", "Tigerdirect", and "Newegg".
DDR2 667MHz
Yes, it is backward compatible
You can use 240-pin DDR2 667MHZ. And this mother board supports dual channel.Hope this helps.
Probably. For DDR/DDR2/DDR3 memory, you take the MHz number (667) and multiply it by 8 to get the PC-xxxx number. In this case, it would come out to 5333 MB/sec, which is the amount of data the memory can process, theoretically. The 5300 and 5400 numbers are just approximations of 5333, used for marketing. The really important part is the 667 MHz.
