UPGRADE RAM from8 to 16gb

[mirko-pi]

Dear, i have installed this RAM in my pc desktop HP Pavillion SK Hynix 8GB DDR4 2666MHz. with MB 843c

I want to upgrade my pc., and  i have found this ram on amazon but the price is 90 euro. There is something comparable less expensive?

Thanks

@mirko-pi,

Yes, preferably you should use identical RAM (same brand, model and capacity/speed), but sometimes that can be difficult to achieve.

Here is a very similar 8GB Crucial RAM stick you can purchase for less than 27€ via Amazon-Italy: Crucial RAM CT8G4DFRA266 8GB DDR4 2666MHz CL19 Memoria Desktop, ‎Multicolore : Amazon.it: Informatic..., or here is one for less than 17€: Timetec 8GB DDR4 2666MHz PC4-21300 Non ECC Unbuffered 1.2V CL19 1Rx8 Single Rank 288 Pin UDIMM Memor....

@mirko-pi,

Dual rank RAM can run faster than single rank RAM.  See it as the difference between a room with one door (single rank) vs. a room with two doors (dual rank).

Hi,

thank.

now my ram is single RANK, but my desktop supports both single and dual?

Any desktop accept both?

I have found also this on amazon-de 

https://www.amazon.de/dp/B08C4LXXCJ/?language=de_DE&cstrackid=c95b0414-8c03-4f95-806c-98198dbe1ac8&t... that have more latency than timetec.

@mirko-pi,

Yes, your PC will support both single and dual rank RAM, but do not mix the two: stay with a matching RAM kit.

Yes, the Crucial RAM you referenced should work just fine!
