Is DDR4 xxxxP the same as DDR4 xxxx?

[chctulc]

Take slow DDR4 2133P as an example. I have been told that the "P" stands for parity meaning it is server RAM (ECC) and not desktop RAM. But I have my doubts. Can anyone here confirm it one way or the other? I'm wanting idesktop RAM.

No, the P does not stand for parity. The suffix letter is the JEDEC timing spec identifier:

Thank you. So, it is usable as desktop memory then, right?

yes, iirc it is the default speed of DDR4 anything above is OC'd (someone correct me if i am wrong) if a stick is 2400 say, it is clocked higher by the sticks bios/firmware (is this correct?)

You are correct, and at the end, you are looking for the Spd, which can be set just as an XMP/DOCP can.

An example, Corsair released new ram where the board defaults sets this kit to 2133. If you just stick them in a board, the SPD profile delivers 3200, yet the xmp shows 3600.

Should be unless otherwise indicated.

Thank you all for your enlightenment. Memory isn't my strong suit.
