Ddr2/Ddr3 Switch Card Nedir?

quote:



When you use DDR2 SDRAM, you should install DDR2 / DDR3 Switch Cards into empty DDR3 slots. If the board is working with DDR3 SDRAM, Switch Cards should be turned upside down and installed into the empty DDR2 slots. They have corresponding contact layouts on both sides. There are also certain rules: with DDR3 memory the Switch cards should go into the second and fourth DDR2 slots, but if the board is working with DDR2 SDRAM, you don’t really have much choice: there are only two DDR3 slots on the PCB, where these Switch Cards can go. However, if you intend to overclock the memory beyond DDR3-1333MHz, the Switch cards should be removed.
