Upgrade Refurbished 2133MHz LPDDR3 Thinkpad T490 with 32GB 2400MHz DDR4?

2021-07-22, 8:52 AM

Good day,

 

I'm planning to buy a refurbished T490 from the following website: https://www.lenovo.com/us/en/outletus/laptops/thinkpad/thinkpad-t-series/T490/p/20N2X010US

 

However, it's intriguing and at the same time confusing the configuration has a Lower-Power DDR3 ram (LPDDR3); while the CPU supports up-to 2400MHz DDR4. Would a upgrade of 32GB 2400MHz DDR4 work with this laptop (check attached link)?  Would this 8GB (LPDDR3) add up with 32GB (DDR4) to become 40gb?

 

Please, I would appreciate the community in this matter prior to make my purchase decision.

Hello Marukox!


Welcome to community forums

 

 

The CPU may support both ddr3 and ddr4 but the physical slot onboard for the ram is for DDR3. This would be similar to those listed under Commodity list > Memory here in parts lookup; https://pcsupport.lenovo.com/ph/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t490-type-20n2-20n3/20n2/20n2x010us/parts/display/model?fbclid=IwAR2-uNEpbtJDW5Ng-jWkwlGRZKwmUCxfQc6Jmi4ibBzhrcs_nqbmVRKwvxw

 

Here is also the hardware manual for added reference https://download.lenovo.com/pccbbs/mobiles_pdf/t490_hmm_en.pdf

 

Regards
