Hi MelonMan,

 

Welcome to the Community Forums.

 

RAM usually clocks down to the speed the current ram is installed with. 

If it has two ram of different speed, it would clock down with the lower speed.

 

You can try to check your installed ram from parts lookup here.

 

Hope this helps answer your query.

 

Regards

Hi MelonMan,

 

It depends on the ram installed.

As example, using MTM 20H40006US for a E475 Laptop showed parts number 01HW756 FRU 4GB DDR4 2400 SoDIMM.

 

You can check here on the relationship of bandwidth and frequency on double data rate how DDR4-2400, PC4-19200 and expected I/O bus clock of 1200 MHz (1200 X 2 double data rate= 2400).

 

You can also check your using your serial number here on the parts lookup page for the memory installed on your system.

 

Regards

It is strange since task manager shows it at 1200, but CPU-Z shows it at 988. I ran bench marks at it showed that my ram was extremely slow, down to the third percentile of the same model
