  • Product Title 4GB DDR2 800Mhz PC2-6400 240 Pin 1.8V Desktop Memory. Average rating: 1.5 out of 5 stars, based on 2 reviews 2 ratings Current Price $16.16 $ 16. 16 List List Price $45.84 $ 45.
  • The two run on different power supply voltages. If you did manage to get a DDR2 ram into your DDR slot (and I'd be very surprised to find that they're keyed in a way that makes this physically possible) then your laptop's 2.5V DDR RAM power supply would toast your 1.8V DDR2 RAM.
  • DDR2 SDRAM use 240-pin DIMM sockets for desktop computers. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered modules), so they are installed one at a time in 64-bit systems. DDR2 chipsets are expected to support dual-channel memory, providing a 128-bit data path. 240-pin DIMMs are available in DDR2 or DDR3 SDRAM.
  • Would it work to put 2gb ddr2 ram into a slot, that only support up to 1gb ram?? I have a sony vgn-c140g laptop that supports a max of 2gb ddr2 ram. Somewhere in the manuel, it said it only support a max of 1gb ddr2 ram per slot.

A friend has an older laptop which uses PC2100 DDR-266 200 pin SODIMM's. I have a P2-5300 DDR2-667 200 pin SODIMM left over from an upgrade.

It looks to me that both are keyed in the same spot on the RAM so I'm wondering if my DDR2-667 RAM would work in the DDR-266 slot.

I don't care that about the fact that this is like putting a car engine in a lawnmower, I just want to know definitively if it will work without damaging the RAM or laptop.

I'm not looking for guesses, I need a yes or no from someone that knows about RAM.

Speedwize it should be ok, it will just run at the lower speed, however i am not sure about it being a different type of DDR though. I dont think DDR2 work in pcs which are meant for DDR1
