Upgrading ram

[MrSagar17]

My laptop is Hp victus rx 5500m graphics 8 gb ram 

I wanted to upgrade my ram

so I purchase 8gb ram of brand sk-hynix which is same brand fitted already

Model is HMA81GS6DJR8N-XN 3200AA speed of 3200MHz

But when I add my ram my speed limit goes to 2667Mhz in task manager

Now I am confused is it issue ram maybe they showing 3200 and giving 2666 showing wrong specs in label 

or do I need to some settings in laptop to overclock the speed

And it is dual channel but original ram speed is 1600 and upgraded ram speed is 1333 Mhz in HWinfo software 

Pleasr help me

When you upgrade the installed RAM and want it to work as expected the first time you power it on there are some considerations you have to make.

You mixed memory that was the same brand, but that was not identical in all respects and what happened is what I would have expected. 

Identical in all respects means, brand, number of memory modules, same as in single sided or dual sided and same speed, same vDIMM, same primary and secondary timings.

Memory will always downclock to the lower speed if modules have differing speed. That is something that will not change.

Consider yourself lucky that both modules are recognized by the BIOS and the OS.

I would expect that the modules are probably not running in dual channel mode either.

Well, having same specs does not mean absolutely identical in all respects .

According to your first post their is an issue.

I suggest that you read my first post again.
