Question How to match soldered ram?

[Stef Zia]

So I want to upgrade my laptop's RAM from 8 gb soldered to 16 gb (it has one free slot). One reason I want to upgrade my RAM is to be able to utilize Intel Iris Xe graphics (CPU: i5 1235u) because my laptop really laggs when i add a second monitor.

First Question: Will I have better performance when on two screens?

Second Question: How do I match my RAM with the soldered one? (And is it neccesary?)

My laptop is Lenovo v17 g3 iap with :i5-1235u, 8gb Ram, 512 gb NvMe

I am adding photos of the laptop slot and soldered RAM from CPU Z.

Unless you have a ball grid soldering station to de solder and re solder the ram you're going to have a tough time doing this. They also dont sell these ram chips outright, you will have to source them from a company or find a busted laptop to harvest them from.

Will I have better performance when on two screens?

doubt it. increasing ram a bit could help (set the igpu ram size in BIOS), but not much if it already lags a lot.

How do I match my RAM with the soldered one? (And is it neccesary?).

yes it is necessary. that being said, some laptops don't even accept new RAM which aren't OEM. specially since yours is soldered, I doubt it was meant to be upgraded in the first place, despite having another free slot. even if you manage to find one similar to the soldered one, it still has a high chance of not working.

I don't want to desolder my existing ram. I want to add a new stick(check the photos I have added)

Go here and run the scanner see what it shows.

Unfortunately, there is no igpu ram size in bios.

It says that I can add up to 32gb ddr4 memory stick

if it has a specific limit set, then, bummer, adding more ram won't solve your problem.

 

[geofelt]

Adding a second stick is a good idea and will improve your igpu performance.
A second stick of ram will operate in dual channel mode, effectively doubling the ram speed.
IGPU is one place in Intel systems where ram speed matters.
You may also be able to allocate more dedicated space for the igpu to work with.
The bios setup screen is where this option may exist.
The other possibility is the Intel igpu display settings.

If you installed a second ram part greater than the original 8gb, 8gb of it will still operate in dual channel mode and the remaining odd capacity will operate in single channel mode.
This is called flex mode.

Picking the Crucial parts will pretty much assure you of compatibility.
Other ram of similar specs are also likely to work.
Unless you need more than 16gb, I would just get the extra 8gb stick.

OP said such a setting cannot be found in his BIOS. assuming the iGPU's dedicated space is fixed.

 

[geofelt]

If there is no such setting in the bios, the amount of dedicated vram may be dynamic, based on the total amount of ram available.
Going to 16gb may in effect increase the vram.
The boost from added vram will be nowhere near the boost from going to dual channel operation.
Here is a link to see how much is allocated:

Looks like about 17 bucks to double the ram you have and enable dual channel.......should be a bump in perf.

had a same laptop with Ryzen. it had a slot free. i tried two different 8gb which i had from another laptop, and both worked fine for me. i tried the passmark, the score was almost the same. basically its safe to go with crucial or Sk.hynix. (those are the brands i tried with the same results)

also i strongly suggest that you do so. the performance boost is noticeable in iGPU part. at least for AMD...
