Lenovo Ideapad 510S-14IKB no post with recommended CT8G4SFD824A

Lenovo Ideapad 510S-14IKB (80UV001BUS)


Bought this 8GB module off of Amazon: https://www.amazon.com/Crucial-Single-PC4-19200-SODIMM-260-Pin/dp/B019FREJOQ

Which is the same as the one recommended for this system by Crucial: https://www.crucial.com/usa/en/ideapad-510s-14ikb/CT9691947


No post. Originally thought the laptop had 4GB soldered on with 4GB installed, but realized it only has one memory slot with an 8GB module already in it. This is the one it had in it, 8GB Ramaxel RMSA3260MB78HAF-2400 (SM30G16511): https://www.memory4less.com/ramaxel-8gb-sodimm-pc19200-rmsa3260mb78haf-2400

Says single rank and has the M with the circle around it on the chips.


When I installed the 8GB Crucial CT8G4SFD824A module, it would not post. No BIOS screen just powered up and nothing. Is it something wrong with the laptop or the RAM module? Bought it because it seemed to be the most compatible module Crucial has for many laptops of the same generation on Amazon and for a reasonable price. I did read that some systems only work with single-rank memory. I didn't think a newer Intel chipset like this couldn't use dual-rank memory. Even checked on Intel's site for this laptop's processor i7-7500U and says it can support two memory channels. Maybe my system doesn't like its speed, even though the stock one says 2400 in its part number.


I was meaning to upgrade to at least 12GB but now I need to get a 16GB module but am wary of trusting Crucial's compatibility tool if it won't work like this one. Didn't see any recommendations for single rank 16GB modules on Crucial but should I try a dual rank 16GB module and see if it works or just go ahead and get a single rank 16GB module (CT16G4SFD824A) that's on Amazon but not recommended on Crucial?

That part should work with the 510S-14IKB. We have some internal sales history where people have purchased this memory for that system, with no returns, so I assume the memory work for them. I don't see any reason the 16GB variant of the part wouldn't work as well.

We also list Ballistix memory for the system, so both BLS16G4S240FSD and BLS16G4S26BFSD should work with the system as well.

Possibly flashing the BIOS with the latest one from Lenovo would be warranted in this scenario.
