which RAM type for Inspirion 15R 5521 ?

Jump to solution

I have an Inspirion 15R 5521 with Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz and dedicated video AMD Radeon HD 8730M

Inside I have 4GB DDR3 model Hynix HMT351S6EFR8C-PB.

It is clearly stated that this is 1.5 V memory and hwinfo or CPUid says the same

However on DELL official support and Corsair, Kingston...it is written that I shall buy DDR3L (1.25V) for upgrade

I am confused ...what 4GB SO-DIMM is suitable for me?

DDR3L is now much more common and will work with your system.

I know that these days DDR3L is very common but will my system work?

I already have 4GB DDR3....will it work mixed?
