Can I replace PC2 5300 with PC2 6400?

PC2-6400 is backward-compatible for PC2-4200 and PC2-5300.

What PC2-4200?

DDR2 PC2-4200 (commonly referred to as DDR2-533) memory is DDR2 designed for use in systems with a 266MHz front-side bus (providing a 533MT/s data transfer rate). 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.

Is ram downward compatible?

Unless the number of pins in a DIMM has changed from one specification to another, generally it’s possible to put faster RAM into a slower slot and in that way RAM is “backwards compatible” with older, slower computers (e.g. I’ve put PC-133 SIMMs into PC-100 slots on motherboards and that worked), but one still must be …

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.

Which is the same module as pc2-4200r?

PC2-4200R is a registered PC2-4200 module, PC2-4200R ECC is the same module but with additional ECC. Be fully buffered modules, which are designated by F or FB and do not have the same notch position as other classes.

What’s the memory speed of a crucial PC2-5300?

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.

What does ECC mean on a PC2-4200?

PC2-4200 ECC is a PC2-4200 module with ECC. Be “registered”, which improves signal integrity (and hence potentially clock rates and physical slot capacity) by electrically buffering the signals at a cost of an extra clock of increased latency.
