[SOLVED] Will this laptop support higher size and speed RAM?

[Mahesh Abnave]

I bought Lenovo S145 15IIL laptop (model 81W800FLIN).
It comes with 8GB soldered RAM which seem to run at 2666 MHz.
The processor is 1031G1 which seem to support 64GB @ 3200 MHz.
Lenovo says max 12 GB is supported. But some people have upgraded above 12 GB too.
For example in this video it is shown to work with 20GB RAM.
Will adding 16GB RAM (total 24GB) work? Possibly at higher data rate? Or I have to stick to data rate of 2666MHz or lower?

Maximum overall is 20GB. If got 8, then get another 8GB.

Would rather 2x 8GB in full dual channel anyway vs say if laptop came with 4GB soldered and got 16GB stick where only 4GB of the 16 would be in dual channel.

ohh Do you mean for dual channel, memory sizes should match?

For complete dual channel yes, capacity should be the same. Odd capacities will be in flex mode.

See last example regarding flex mode.

You have soldered 4gb 2666 ram that can not be changed.
You have a slot with a 4gb module installed.
To upgrade the capacity, which I think is a good idea, you will need to remove the 4gb module and replace it with one of higher capacity.
That would be up to 16gb, giving you a total of 20gb.
All ram must be run at the same speed. Since your current 4gb is 2666, there is no sense in adding ram capable of higher speed, it will run at the base 2666 regardless.
Not a negative since intel is largely insensitive to ram speed.
While the processor itself will support more and faster ram, it is the motherboard used that determines the maximums.
You can't change that.
Adding a 16gb module will let you run in flex mode.
That is where 8gb of the 20 will run in dual channel mode, and the odd 12gb will be in single channel mode.
That is still good. More ram will usually trump faster ram anyway.

I bought from here. It states 8GB soldered RAM. So was asking where buying 16GB more, making it 8+16 = 24 GB work or not? Especially when the crusial page says 20GB RAM is max.

I'd go by Crucial, they do the work testing. Get another 8GB by them and call it a day.

If you look at the specs you linked, it says 4gb soldered ram Plus 4gb sodim.
It is the 4gb that can be replaced.
I suppose you could take the case off and check for yourself. The ram card will have the capacity printed on it.
I think Crucial is correct at 20gb.

Yeah looks like Geo is right about the soldered 4GB. And Crucial says the same. Unless somehow this model released with an 8GB stick, you should be able to verify with Cpuz.
