Is 800 MHz RAM compatible with 667mhz?
Yes, in general, you can use memory of any speed as long as it fits.
What is the core RAM clock speed for RAM with a DDR2?
Ram Chart
| Module Type | Chip Type | Clock Speed |
|---|---|---|
| PC3-6400 DDR3 SDRAM | DDR3-800 | 400 MHz |
| PC2-7200 DDR2 SDRAM | DDR2-900 | 450 MHz |
| PC2-8000 DDR2 SDRAM | DDR2-1000 | 500 MHz |
| PC2-8500 DDR2 SDRAM | DDR2-1066 | 533 MHz |
What RAM is compatible with DDR2?
All DDR memories are mutually incompatible. The DDR2/3/4 DIMMs can only be used on their respective DDR2/3/4 sockets, with the notches differently located. The power supply for each generation also varies: for DDR1 DIMMs, it’s 2.5V; DDR2, 1.8V; DDR3, 1.5V; and DDR4, 1.2V.
What is the frequency of DDR2 RAM?
DDR2 memories include 400 MHz, 533 MHz, 667 MHz and 800 MHz versions, while DDR3 memories include 800 MHz, 1066 MHz, 1333 MHz and 1600 MHz versions. Both types double the data rate for a given clock frequency.
What is the core RAM clock speed for RAM with a DDR2 speed rating of DDR2-800?
Ram Chart
| Module Type | Chip Type | Clock Speed |
|---|---|---|
| PC2-6400 DDR2 SDRAM | DDR2-800 | 400 MHz |
| PC3-6400 DDR3 SDRAM | DDR3-800 | 400 MHz |
| PC2-7200 DDR2 SDRAM | DDR2-900 | 450 MHz |
| PC2-8000 DDR2 SDRAM | DDR2-1000 | 500 MHz |
Can I install DDR2-800 instead 667?
So long as you purchased PC2-6400 DDR2-800 DIMMs in an appropriate capacity, you can safely use them in place of the PC2-5300 DDR2-667 units specified for use with your particular machine.
Is DDR2 memory compatible with DDR3?
DDR3 SDRAM stands for double data rate type three synchronous dynamic random access memory, and it is the big brother of DDR2 SDRAM in the DDR family. However, DDR3 RAM is not backward compatible with DDR2 (or DDR for that matter) due to differences in signaling, voltages, etc. DDR3 RAM can transfer data at a rate that is twice as fast as DDR2 RAM.
Can I use DDR2 memory in a DDR3 motherboard?
YES it is possible, BUT you have to find the right motherboad that has a DDR2 onboard controler and DDR2 slots, as well as DDR3 slots (intel has moved the memory controler for those onto the core i7s.
What is DDR DIMM memory slots?
Three SDRAM DIMM slots on a computer motherboard. A DIMM or dual in-line memory module comprises a series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers.
