Laptop lagging after RAM upgrade and clean install.

I recently decided to upgrade the stock 8gb RAM in my Lenovo L340 laptop and replaced it with a stick of 16gb. I also replaced the stock m.2 storage (512) with a 1tb stick. I then performed a clean install of Windows 11. However since doing so, something just doesn't feel quite right with the laptop's performance. Both components seem to be working fine, but the laptop itself just feels a bit laggy? Small things like a very slight delay in seeing text appear as I type, or a very slight lagginess with windows opening or closing from the taskbar, or scrolling a page. There's no smoothness to it any more... Any ideas?
 
Were you on windows 11 before? Also what RAM did you upgrade from? And what speed is your new RAM.

worth making sure XMP is enabled for your RAM.
 
I upgraded from 8gb DDR4 to 16GB DDR4 3200MHz SODIMM CL22 though on checking the task manager under Memory>Performance I've just seen it says the speed is only 2400Hz?
 
Just checked - there is no way to do with the Lenovo's idea pad series. Looks like I'm capped at 2400. However, this lagging/stuttering issue was not occuring before the upgrade, when I was only using 8gb @ 2400. Any other thoughts?
 
Ok thats a surprise but will admit I'm more used to desktop than laptops. So were you running Windows 11 before the upgrade?

and what were to two models of SSD's, new and old?
 
Yes, W11 before. SSDs were both Samsung Evo Plus
I'm thinking it could be some driver issues? Is there a way to clean remove/install all drivers?
 
Not in one go, it could be software related. Do you have the old SSD still that you could chuck in and compare. I don't know exactly how windows caches everything but I know it does cache things like thumbnails etc in folders and this takes time to build up.
 
Use task manager and/or Process Explorer and see what is going on in the background - a new Windows install can take awhile to "sort itself out" sometimes with things like .net components and malware protection taking a good 40+ minutes of background processor time before they settle down and/or get stuck in a loop. Windows 10 and 11 don't seem to like laptops much sometimes either with errant maintenance tasks going a bit wonky chewing 100% of 1 CPU core, etc.

You may have lost significant performance from reduced RAM speed. I don't think your laptop supports over 2666mhz though so it may not be that.

Not all RAM rated as 3200Mhz is equal. Some have a true JEDEC profile for 3200mhz. Others have a much slower JEDEC profile and the 3200mhz is an XMP profile, sometimes at a higher voltage. If your laptop doesn't support XMP then you're out of luck.

I'd change back to the old RAM. If that fixes your issue you can either leave it or buy the right RAM if you need more.

ram speed wont fix that. last time i got lag when typing in word processor was with a 80286 cpu.
 
Have you tried using Snappy Driver Installer Origin to see what drivers are missing and to update the existing ones? If not, try this.

Don't select updates for input devices, namely the keyboard and touchpad. A couple of times I've updated touchpad, keyboard and the input-related devices and the touchpad simply didn't respond to anything. Rolling back and removing the drivers worked, until Windows decided it'd like to reinstall them again. :(

Did you try putting the old RAM back in to see if the problem is still there?

This is how you tell what the issue is.

I've mixed RAM modules before and it hasn't been an issue but laptops can be difficult little things. Their BIOS is usually very locked down.

Could be the BIOS not being happy with the RAM but unless you test the old RAM in it, you won't know.

Exactly.

I purchased a new Lenovo laptop last year. Gen 11 i7 CPU, upgraded the RAM myself. Then started getting issues with the BIOS auto repairing itself every few days or failing to boot. Put the original RAM back in and the problem never happened again.

Does your Lenovo use soldered RAM? When I had a look on their website, all of their laptops used soldered RAM.

This would probably explain the issues - I put an extra 8gigs in my Asus TUF FX505GM laptop and it was fine, even though the one in the laptop was an OEM brand and model and I put in Kingston HyperX.

8GB soldered and 8GB removable.

I purposely purchase the laptop so I could upgrade the RAM. I got a similar one for my girlfriend 16GB but RAM is soldered so cant upgrade it.

Seems only their higher end laptops are not using soldered RAM, same for Dell laptops too. Starting to take ideas from Apple. :rolleyes:

Hate soldered RAM. It's cheaper, sure, but after a few years and you not being able to upgrade it because HTML 6 now chows more RAM than ever, you need to get a new laptop.

Would check upgrade compatibility on the Lenovo and Crucial site - I've found Crucial RAM to be very compatible with systems because they use Micron exclusively.
