DDR2 memory is at the same internal clock speed (133~200MHz) as DDR, but the transfer rate of DDR2 can reach 533~800 MT/s with the improved I/O bus signal. … DDR4 SDRAM provides the lower operating voltage (1.2V) and higher transfer rate. The transfer rate of DDR4 is 2133~3200 MT/s.
although, What is the difference between DDR and DDR2?
DDR2 was introduced in 2003 and operates external data twice as fast as DDR due to an improved bus signal. DDR2 operates on the same internal clock speed as DDR, however the transfer rates are faster due to the improved input/output bus signal. DDR2 has a 4-bit prefetch, twice that of DDR.
Besides, Why is DDR2 RAM so expensive?
It is because it is not manufactured anymore and people still want it. Some people would rather pay $1200 for 16GB of DDR2 (in the form of 4GB sticks) than buying a brand new PC that is much faster with more RAM for much much less.
however What is the fastest DDR2 RAM available? Corsair seems determined to hold the record for the highest memory speed in production memory. We recently reviewed the highest speed memory available at the time in Corsair Dominator DDR2-1111 (PC2-8888).
so that How can I identify DDR1 DDR2 and DDR3 DDR4 physically?
Notch distance in ddr1 ddr2 ddr3 ddr4
If you notice the cut mark all ram has cut mark. There is a cut mark on DDR1 above the chip, as you can see on above displayed picture. There is no distance difference On DDR2 and DDR4, the cut seems similar, so we need to identify them by chip.
Can I use DDR2 in DDR1 slot? If i end up using ddr2 ram chips will they work in a ddr1. No, you can’t. Yes. If memory serves DDR2 is keyed differently anyway, so it wouldn’t physically fit.

How do I know if my RAM is DDR1 or DDR2?
In all DDR, the notch is at the base of the RAM. In DDR1 and DDR2, the notch cuts look similar. However, in DDR1, the notch is just above the IC while in DDR2, the notch is a bit farther from the IC. In DDR3, the notch is nowhere near the center.
Does DDR2 support 8GB RAM?
DDR2 DIMMs are neither forward compatible with DDR3 nor backward compatible with DDR. … The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used.
