Can I use DDR2 RAM with DDR3 RAM?

DDR3 is not backwards compatible with DDR2. While both types of modules have similar numbers of pins, the notches in the PCB are in different locations. In other words, a DDR3 module cannot be placed in a DDR2 memory socket, and vice-versa.

Can I use 667MHz ram in 800MHz supported motherboard?

The motherboard will run the RAM at 667MHz instead of 800MHz and everything will be fine. The disadvantage is that you lose a bit of performance from the lower frequency.

Are all DDR2 RAM compatible?

Basically any DDR2 DIMM’s will fit. However, whether these DIMM’s are electrically compatible (with the motherboard) is another matter. Check with memory manufacturers and check the motherboard memory QVL for compatible memory.

How do I make sure my RAM is compatible?

The easiest way to tell if a certain RAM stick will work with your motherboard or not is to look at the motherboard specifications. This should give the details regarding the type, amount and the RAM characteristics that the motherboard can support.

Can I use DDR2 667 instead of 533?

Yes, you can use both sticks of RAM at the same time.

What is the difference between DDR2 667 and DDR2 800?

Originally Answered: What is the difference between ddr2-667 and ddr2-800? Basically different clock speeds. Clock speed is, effectively, how man ‘transitions’ something can make per second. 800 has a faster clock speed than 667, which equates to more transfers-per-second and thus more MB/s in transfer speed.

Are all RAM compatible?

While all desktop RAM generations are the same physical size and shape, they aren’t compatible. You cannot use DDR3 RAM in a motherboard that only supports DDR2. Likewise, DDR3 doesn’t fit in a DDR4 slot. To stop any confusion, each RAM generation has a notch cut in the pins at different locations.

What happens if RAM isn’t compatible?

The wrong type of modules simply won’t work, while RAM with the wrong specs for your PC can underperform. RAM comes in sticks, or memory modules, that snap into the memory slots on the motherboard. RAM that’s incompatible with your system either won’t fit, or won’t function properly.

What is the highest RAM for DDR2?

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.

Can I mix ddr2 667 and 800?

So yes you can mix ram and it might work but their is absolutely no guarantee.

What is the difference between 667MHz and 800MHz RAM?

It’s more or less a capability rating. The 800MHz RAM is rated to provide data to the CPU faster than the 667MHz. However they can both operate at 667MHz or lower or even higher, though if its higher than the RAM is rated for its considered to be overclocked.

Is My Motherboard compatible with DDR2 or DDR3 RAM?

yep, Oron is right, DDR2 and DDR3 are different technologies and the motherboard may not be compatible with DDR3 RAM, So just consult it with your motherboard manufacturer.

How many MB/s does a DDR3 transfer?

DDR3 speeds Friendly name Industry name Peak Transfer Rate Data transfers/second (in millions) DDR3-800 PC3-6400 6400 MB/s 800 DDR3-1066 PC3-8500 8533 MB/s 1066 DDR3-1333 PC3-10600 10667 MB/s 1333 DDR3-1600 PC3-12800 12800 MB/s 1600

What is DDR2 6400 memory?

DDR2 PC2-6400 (commonly referred to as DDR2-800) memory is DDR2 designed for use in systems with a 400MHz front-side bus (providing an 800MT/s data transfer rate). The “6400” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s.

Can I upgrade from DDR2 to DDR3?

Another thing to note is that the pin placement is different between each iteration of DDR memory. Unless the motherboard supports both DDR2 and DDR3, upgrading to DDR3 will not work.
