DDR4 RAM supported for HP Elitebook 840 G1 ?

[TechieAB]

Hi,

Can anyone please suggest if the DDR4 RAM is supported for HP Elitebook 840 G1 model.

This laptop supports total of 16GB RAM. I have 8GB DDR3 in one slot and can I place DDR4 8GB RAM in another slot ?

Thanks

No the physical configuration of the memory modules is different. Your laptop ONLY takes 

Two customer-accessible/upgradable memory module slots with the following specifications: DDR3L-1600-MHz dual channel support

Hello Huffer,

Thank you for your quick help. May I pls know how do I identify the DDR3 RAM with dual channel support ? Is it some code mentioned on the barcode sticker ?

I have the following RAM in my laptop at present:

8GB 2Rx8 PC3L - 12800S - 11 - 13 F3

Thanks.

If you get another chip just like it even from a different vendor it will run in dual channel. Has to be the same speed (DDR3-1600 aka PC3 12800) and voltage (in this case low 1.35 v denominated as DDR3L) and same density (4 or 8 black blocks on the side of the module).

HP Part No. is:

8-GB memory module 693374-001

Hi Friend,

Thanks. I am from Eurpoe.

I have the following RAM in my old laptop which is dual channel but with of less speed. Do you think this old RAM fits into 840 G1 ?

 

[Huffer]

It will fit but likely will not work and if it did it would slow everything down. Buy compatible memory. You will not be sorry.

HEllo Huffer,

I have an HP EliteBook 840 G1 and I want upgrade the RAM,

I have seen that the correct RAM specification must be:

DDR3L-1600-MHz

PC3L-12800

I've found a RAM detailed as

PC3L-12800S

"S" stands for "SODIMM", Small Outline DIMM, module with reduced length; is the form factor of the modules for laptops, it should be the one suitable for my HP EliteBook 840 G1.
So the S is a redundant product description?

Thank You for your support,

best regards
