Re:What is Maximum RAM for S340-15IWL (Intel) platform?

2020-12-06, 4:56 AM

I have a Lenovo Ideapad s340 15iwl-Touch that I got from Costco, with 4GB of soldered memory on the motherboard, and came with a 4GB Hynix RAM stick in the existing single memory slot. Today, I upgraded the 4GB module to a 16GB DDR4-2400 SODIMM 2400mhz Crucial Memory Module (CT16G4SFD824A), and it works! The task manager originally said 8GB in the memory tab, and now it says 20GB.

As for dual channel, I think the Intel Flex Memory system has done the trick. It basically allows the current 4GB soldered memory and 4GB of the 16GB Crucial memory to run in dual channel, and the rest of the 12GB runs in single channel. Performance wise for gaming, I actually noticed an increase in performance, despite switching from dual channel to Intel Flex Memory mode. The game that I ran my laptop on was Cities: Skylines, which is a CPU and GPU heavy game. I was able to get better performance with the 4GB soldered + 16GB stick configuration, as opposed to the 4GB soldered + 4GB stick that originally came when I bought my laptop. This should be the same for other games as well. For other heavy weight tasks such as video editing, it will most likely be good as well.

All in all, the maximum RAM for a Lenovo Ideapad s340-15iwl is 20GB. If you have a Lenovo Ideapad s340 or the Lenovo Ideapad s340 Touch and have 4GB of soldered memory, I highly recommend going for the Crucial 16GB ram stick (note: the one with 2400mhz, not 2666mhz). 



Specifications for my Lenovo Ideapad s340 15iwl-Touch:

Intel Core i3-8145u Whiskey Lake @2.10Ghz

240GB Western Digital SSD

Previously 8GB RAM, now 20GB RAM

Intel UHD Graphics 620

Read the whole discussion and happy to see 20 GB being supported!

I have S340 - 15IIL, didn't see this one being mentioned in the replies but to my knowledge 16 GB would be supported for this one too (or all the S340s in fact). Can anyone confirm?

As far as I know, the Lenovo Ideapad s340 series has either 4GB or 8GB of RAM soldered to the motherboard, depending on which retailer you buy it from. If you have 8GB of soldered memory, yes, it would technically be compatible because you can get a 8GB soldered + 8GB RAM stick configuration (it would not be possible to get it to 20GB, since there are currently no 12GB RAM modules, however if you have 4GB of soldered RAM, it would be possible to get 20GB since there are 16GB RAM modules).

Simply put, it depends on how much soldered RAM you have on your motherboard.

Cool. I have the 4 GB soldered one.

 

I read that you recommended 2400Mhz, is that because you already had it of that frequency previously?

Mine is using 2667Mhz in the slots so I plan to get a 16 GB one with the same frequency.

I recommended 2400mhz since I did not know which RAM speed was compatible with my motherboard. However, if you already have 2666mhz RAM in your laptop, it is safe to say that 2666mhz will be compatible.
