I have the Acer Nitro 5 AN515-51-71QB
And I bought this Ram
https://www.speicher.de/arbeitsspeicher-16gb-ddr4-acer-nitro-5-an515-51-71qb-ram-so-dimm-sp237987.html
Now I'm not sure if 2x 8GB or 1x 16GB will come
and I wanted to ask if I have the 8GB ram (or 1x 4GB ram)
To pack the 16GB Ram?
so I ended up with 20gb ram.
Thank you!
EDIT:
So since many did not understand it!
The question is whether I can add the ordered (16gb) to the original 8gb (2x 4gb). There are only 2 places so it can be max 20gb. Can I do that or does something break there?!
I have it too and have 2 * 8 gb ram in it
As MuckiHD already wrote, check first if there's still a slot free
OK
No one is free, but I knew that before ordering
the question was whether I could do the two RAM together. So 1x 16gb and 1x 4gb
You can't do anything. But a 16 and a 4 goes.
With dual channel no, otherwise yes.
Is it dual channel or not?!
The intel i5 can dual channel, an interesting article I found here:
https://www.tecchannel.de/a/fehlertoleranter-speicher-schuetzt-vor-systemausfaellen-und-datenverlust,402181,17
You can equip them differently, the only question is whether there will be a drop in performance.
So 1x 4 and 1x 16GB are absolute cheese. Only 4GB of RAM are operated in the dual channel, the remaining 14 run single channel. Although you have more memory, you still brake the laptop. Cheaper are either 2x8GB or you add a second 16er. Everything else does not make sense.
"to the originals 8gb (2x 4gb)"
The named laptop should actually be equipped with 1 * 8GB and the second SO-DIMM slot should be empty.
The RAM you linked is 2 * 8GB, so you can only install 16 GB anyway, the same modules should be used if possible.
If the new RAM is 1 * 16GB you can simply plug it in, then you have 24GB RAM and at least halfway dual-channel.
EDIT:
There are 2 * 4GB in the original, cf. https://gzhls.at/blob/ldb/5/5/4/3/763237a9d0d4a0d31903966282bbf4014940.pdf
But the effect is the same.
If the new modules are 2 * 8GB, just replace both, if it is only 1 * 16GB, then only replace one (= 20GB RAM), then you have at least halfway dual channel, unless the RAM clock of the new one is massively higher, that but it shouldn't be. If the old one is 2133 MHz and the 2400 MHz is also accepted by the board, you might consider leaving the old one out.
This will not work, since both RAM cells that are on the mainboard must be the same
No, they don't have to! They only have to be the same size for full dual channel, but only 1 module is even worse than 2 different sizes.
But dual channel with 1 * 16GB does not work at all, so it can leave the additional 4 GB plugged in.
But only 1 * 16GB is even worse.
Is it - if I remember correctly - 8 GB in the dual channel (4 GB per module) and 12 GB (the remaining GB of the 16 GB module) in the single channel for 16 + 4GB?
The device addresses as much memory in the DC as the smallest module has. In other words, he has 4GB running in the dual channel, the remaining 12GB of the 16GB bar are only addressed in the SC. Overlaps are a good 3/4 of the power the DC would bring.
"The device addresses as much memory in the DC as the smallest module has."
I thought as much as the smaller module has on both modules, so 4 GB per module equals 8GB.
Otherwise, with 2 * 8GB, only 8 GB would be addressed after your invoice.
* brooding * Nope, 4 of the 16GB module run in DC and the remaining 12 in SC mode. He only uses 1/4 of the large module with full power.
The new one is 2667 MHz O.O.
is that still possible?
