NEED HELP WITH RAM!

[TIKTOKBANNED]

I have a prebuilt PC from Lenovo. It has 1 stick 8 Gig RAM from SK Hynix 2933Mhz CL19. I want to add one more stick of 8 Gig ram. But I have questions:
1. Can I use any other 2933Hz memory from other CAS Latency? Like CL22 or maybe slower?

2. What if I get another stick for 3000Mhz or 3200Mhz, would that work?

 

Please do recommend and help me with this!!!

 

I have attached a screenshot of CPU-Z for the 1 stick RAM that is currently installed

Ideally you want the exact same stick down to the memory IC version as what's currently in your system. If that's not possible, then you want to try and get the same speeds. Mixing RAM is usually not a great idea, but the odds of anything not working are pretty low. It will just operate at the speeds of the slowest RAM kit.

Pref youd wanna get the same sticks with the same ram die but thats basically impossible, have a look at thaiphoon burner and see what ram ic you have, then find some ram with that specific ic but if you cant then other hynix ics should also work

There are some ram sticks out there that are a lot better than SK Hynix.  What I would recommend is to get rid of the existing ram and get a ram kit for your machine.  Something with two stick of 3000 or something similar, but that is considering that you can get the existing ram out of the machine.  Most laptop machines have their ram mounted to the motherboard permanently.  Check that out first to see if it can be removed, if it can, then great.  If not, then unfortunately your choices are limited but the dual ram kit is your best option.

 

Good Luck.

I added to both of my laptops non-matching stick, 4+16GB and 8+16GB  (especially to 2nd one, there first part of ram is soldered on lg gram). I have no issue.

There is no risk do damage laptop. Both sticks will work at speed of slowest one.

Buy there you can return. Do memtest after installation.
