Ddr3 Pc3-12800u

Is PC3-12800U the same as 12800?

 

No.

I would like an answer from someone who knows. This answer contradicts itself. Said "no" then gave a definition that said yes. And wikipedia is not a reliable source..

 

Hi my friend , you could read the difference between memories

Be "registered" ("buffered"), 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. Those modules are identified by an additional R in their designation, e.g. PC3-10600R. Typically modules with this designation are actually ECC Registered, but the 'E' of 'ECC' is not always shown. Whereas non-registered (a.k.a. unbuffered RAM) may be identified by an additional U in the designation. e.g. PC3-10600U.

as Eldon told you before

 

The PC3-12800 is non ECC, unbuffered and the PC3-12800U fits the same description.
So these are not the same??
