FAQ about Lenovo IdeaPad S145-14AST RAM
How much RAM can I put in the Lenovo S145-14AST?
Maximum is 16GB. It's got just one memory slot, so you'll need to replace whatever's in there with a single 16GB stick if you want to max it out.
What kind of RAM does the S145-14AST use?
It takes DDR4 SODIMM - that's the smaller laptop memory, not the full-size desktop sticks. Make sure you get SODIMM, not regular DIMM.
What speed RAM should I get for the S145-14AST?
Go with 2400MHz DDR4. That's also labeled as PC4-19200 if you see it listed that way. The laptop won't benefit from faster speeds, so save your money.
Can I add RAM without removing the existing memory?
Nope, this laptop only has one RAM slot. Whatever memory came with it needs to come out if you're upgrading. No dual-channel option here.
Is 8GB enough or should I go straight to 16GB?
Depends what you're doing. 8GB is decent for basic stuff - web browsing, documents, light multitasking. If you're running multiple programs, keeping lots of browser tabs open, or doing any photo editing, jump to 16GB. Since you only get one slot, might as well max it out if you're already opening it up.
