so dumb me just decided to check cpuz and hwi info on my very old PC and found out ram is running at 665.1Mhz(as shown in CPUZ) but my BIOS shows it at 1333Mhz

i have searched for bios driver updates(thinking that might fix it) but intel has removed those which were hosted till last year. and most third party websites look like they are hosting adware

Double data rate (DDR) is the advanced version of synchronous dynamic random access memory (SDRAM).
DDR Dimms are double data rate so 665x2 = 1333. No issue there.
You have one 8GB ddr3 DIMM in single channel mode.

if u have dual channel memory its fine that speed 1333/2 is equal that
