OK! EF Tech masters. I have a question that maybe you experts can answer.
Want to upgrade old Aspire V3-772
Crucial has a scanner that says it has 4 slots.
2 of which are occupied with 4gb Micron Tech 1600 ram
and that it can be upgraded with thier 8gb DDR3L-1600 SODIMMs

Now in comparison shopping have found the ram at Digitec and another lower priced brand.
Can any of you tell not so knowing me what is the diff besides price?

These are the two rams:

Also can the 2 4gb rams be kept in with the new 8gb rams or will incompatibility be a problem?

Any advice and or recommendations would be appreciated. Thanks!

From specifications, both memory modules are identical: DDR3-1600. L or SODDIM means the physical size of the modules: they fit a laptop motherboard.

For RAM, capacity (8GB) and data transfer rate (1600, forgot the units) matter. So, both memory modules are the same.

Albeit, the data transfer rate is usually limited by the motherboard of your computer. Even if the memory is able to run faster, the computer makes it runs slower or may not be compatible at all. Just make sure in your computer specifications that it is compatible with DDR3-1600 modules.

Thanks. The manufacture installed 4gb rams are already DDR3-1600, so assume the notebook must support it.

CAS Latency might be different on the cheaper one, although it won't be an issue for your usage.

So you have 4 RAM slots? And you are planning to use 2 x 4GB from one manufacturer and 1 x 8GB from another and leave the 4th slot empty?

Mixing RAM should be ok in theory, but sometimes it can cause issues You might have to refer to user guide to see which slot to leave empty. Also make sure your laptop/MOBO allows 8GB on a slot. Max RAM for your MOBO/laptop, 32GB (8GB x 4)?

Not exactly! I want to use the 2 currently empty slots to install 2 additional 8gb modules to have a total of 20gb. According to the crucial scan an upgrade to 8gb per slot is recommended. Actually, the current 4GB ram is from Micron which owns Crucial.
So! Basically, if there is no difference between the V7 and Crucial RAM, I'll go with the V7 and save myself 40 SFr..

I guess you are guessing ... and trying to justify one guess over another one with 40CHF of 'win'(risk reward).

Matter of principal.
Why should one pay about 60% more for the same thing?

Update!
Picked up my order today and snapped the 2 new 8gb of V7 RAM into the 2 empty slots and wham bam notebook runs like a gem. Interestingly I not only saved 40 Sfr but I got RAM made in the UK. Never occurred to me that the Brits are still producing RAM. And believe it or not the more expensive Crucial RAM is made in China. Try to figure that out.

You do know that digitec have a comparison function?

The cheaper one is four years newer. DOA shorter. Warranty much shorter (2 years as opposed to 30! - although I've only once in 20 years had a memory chip fail).
