What does PC6400 mean?

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. DDR2 PC2-8000 (commonly referred to as DDR2-1000) memory is DDR2 providing a 1,000MT/s data transfer rate).

Can I use PC6400 instead of PC5300?

You can use PC6400, but it will run at PC5300 speeds. It might offer better timings, but the effect on performance will be next to nothing.

Does DDR2 support 4GB RAM?

The reason for this is that 4GB is the maximum supported by 32bit systems, which DDR2 was for. Because of the 32 bit limits, and the nature of dual channel RAM, the highest capacity DDR2 sets are going to be 2x2GB sticks.

What is the difference between PC2-5300 and 6400?

The “5300” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 5300MB/s, or 5.3GB/s. PC2-5300 is backward-compatible for PC2-4200. 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 mix ddr2 667 and 800?

It can work but mixing RAM of various speeds can cause some stability issues. You will likely end up having tweak the bios to run at the 667mhz speed and also very likely will have to tweak some CAS latencies to loosen it up some for running 4 sticks.

What happens if I put DDR3 RAM in DDR2 slot?

DDR3 is not backwards compatible with DDR2. In other words, a DDR3 module cannot be placed in a DDR2 memory socket, and vice-versa.

What’s the difference between PC2 6400 and PC2 5300 Ram?

PC2-6400 is capable of running on a faster bus (400 MHz, 800 effective) than PC2-5300 (333 MHz, 667 effective). Assuming you have a notebook computer, no current notebook using an Intel chip (set) can run RAM at 400/800 MHz – there’s no point in buying PC-2 6400 RAM.

Can a 6400 stick be used with a PC2 5300?

I have an XPS 1710 and I’m intending to upgrade from 2×1 gb 667 mhz to 2×2 gb. My question is, if 6400 sticks are 200 pin is it possible and appropriate to use the PC2 6400 with 800 mhz in a system that was formerly PC2-5300 or will there be dire consequences?

Is it possible to use a PC2 6400 with 800 MHz?

My question is, if 6400 sticks are 200 pin is it possible and appropriate to use the PC2 6400 with 800 mhz in a system that was formerly PC2-5300 or will there be dire consequences? My system died and I was advised it was the hard drive though I’m still thinking it was the mother board.
