You can use 240-pin DDR2 667MHZ. And this mother board supports dual channel.Hope this helps.
No.
Yes
No, DDR and DDR2 are different types of memory. DDR2 supports higher speeds and has different socket. Check your laptop manufactore website to find out which type of memory your laptop works with.
Ya sure you shall go for it It will run at the slower clockspeed though, but not a big issue.
No DDR and DDR2 Slots are differant on Motherboard so cant replace each another
That depends on your motherboard. Most Prescott motherboards did not support DDR2 RAM.
The ASRock G31M-S uses DDR2-667 or DDR2-800 modules. it supports up to 8 GB of RAM using two 4 GB modules.
sorry bout this, but the md2614u only supports ddr2 memory, and the limit on RAM is 4gb.
The type of RAM you use is dependant on what your motherboard and CPU can handle. You want to change from DDR to DDR2? Id' recommend getting a new computer.
the different notch positions keep someone from installing a DDR DIMM or DDR2 DIMM in the wrong memory slot.
