RAM upgrade of Lenovo Yoga 520-14IKB (Type 81C8)

2019-10-28, 8:22 AM

Hello,

I want to upgrade my RAM, or instead, I should say replace my RAM(as there is just one single slot available).

 

The only thing that I am still confused about is the required bandwidth, as it is nowhere mentioned in HMM of my laptop given in the Lenovo support website.

I've been through this forum, but the HMM(Hardware Maintenance Module) details don't match the HMM details given for my laptop(refer to the attached screenshot). 

 

Just Help me with the bandwidth that I should purchase. I am not sure, but as far as I know, it's either 2133mhz or 2400mhz.

 

info: I am using Lenovo Yoga 520-14IKB(81C8) since Feb 2019 with intel i3 8th gen processor and 4GB ram (don't know what bandwidth it is).

Solved! See the solution

Hi rahuljain073,

 

Welcome to the Community Forums.

 

For the Yoga 520-14IKB model type 81C8 general specification "Up to 16GB max / 2133MHz DDR4, one DDR4 SO-DIMM socket".

 

This can be different regionally like 81C80026FR 1x 4GB DIMM DDR4-2400. It can also support 2666MHz as offered here in parts lookup. So all 3 frequencies are supported depending on availability in your region. Getting the fastest is favored.

 

I hope this helps answer your query.

 

Regards

Re: RAM upgrade of Lenovo Yoga 520-14IKB (Type 81C8)

I did some research about the processor(i3 8130U) and found that it supports DDR4 2400mhz. So, I think that's my answer and that's what I am going to need. Also, I opened the back and took out the RAM and found it was written PC4-2400T(see the attached image).

I just need one more help with my RAM purchase and my question is:

Does it make sense to buy a 16gb ram with an i3 processor because even with 16gb of ram I will not be able to run any heavy programs(like photo editing or gaming) due to my low processing power? So it sounds pointless to me to buy 16gb of RAM. 

Should I buy 8gb ram or 16gb considering my low-end processor and integrated graphics? Please help me?

 

Thanks for the help. :)

Hi rahuljain073,

 

When doing upgrades, it is the OEM specifications through the hardware manual and official documentation that is needed to consult as mentioned on the reply. It is better this way instead of just the CPU (DDR4-2400, LPDDR3-2133) handle since end configuration can be changed by the OEM as they configure the BIOS support. 

 

Added ram surely would help for additional resources but the decision would always be with the user and actual performance with the RAM to decide if 8GB is enough or if 16GB would.

 

I suggest you check it with your colleagues that have the same apps and specs on what works best for them too.

 

Regards

Hi rahuljain073,

 

Greetings.

 

You can check with technical support or privately message me the serial number. Likewise running CPU Z can also give some data.
