The type of memory used by the graphics card. DDR1 is slower, DDR2 is faster. They both plug into the same slot in your computer.
No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
If the port on your motherboard is an AGP slot then it doesn't matter if you have ddr or ddr2
A DDR2 memory stick cannot be installed correctly in a DDR slot.
Short answer is no.They are not interchangeable.
Memory Type: DDR2 PC2-6400, DDR2 PC2-8500, DDR2 (non-ECC)Maximum Memory: 8GBSlots: 4Each memory slot can hold DDR2 PC2-6400, DDR2 PC2-8500 with a maximum of 2GB per slot.
No, you cannot use a DDR-2 5300 memory module in a Toshiba Satellite A60 or A65 laptop. This module will not fit into the slot. You can install up to 1GB memory module into the expansion slot, but it has to be DDR memory, not DDR2. Here's what you can use: PC2700 (DDR333) module: 256MB, 512MB or 1GB.
No, you can't. First check your type, Is it DDR1, DDR2, DDR3 or maybe something else. When you know your type, in your case DDR1, you have to check the speed. DDR1 has 333 or 400, DDR2 has 553,667,800 or 1066, DDR3 has 1066,1333,1600,1800,1866,2000,2133,2200 or 2300 and even higher. In your case 333 or 400 speed. So you can replace your DDR1 depends on your speed for a 512GB, 1GB or 2GB RAM. But you have to check what is max. to place! And you can place DDR3 if you want, but then you have to change motherboard. And in that case better to buy a new computer. Sorry for my english :)
Memory Ram
the different notch positions keep someone from installing a DDR DIMM or DDR2 DIMM in the wrong memory slot.
DDR2 PC2-4200,DDR2 PC2-5300,DDR2 PC2-6400 with a maximum of 1GB per slot (equals 4GB max total system memory)
You are speaking about the RAM ? Just remove your old RAM from the slot. Buy a 1 GB RAM ( be carefull that your new RAM should be same frequency (FSB) that is supported by your motherboard and same size ( i.e. SD, DDR, or DDR1, or DDR2, or even now DDR3 or other ).
