IS THIS OK...?
While checking the RAM specs, I noticed a 1337Mhz number in the bracket—it seems a bit odd. However, in the Task Manager it shows 2667MHz.
your processor is an i7 9750h with a top speed of up to 2667mhz
1333 times two equals 2666. DDR means Double Data Rate. Your RAM runs at 1333 MHz, but it's increased to 2666 for better performance. That's standard.
Thanks mate!
