I have a laptop running Linux with a 4GB RAM stick that came with it. It's a DDR3 1066 MHz stick. I also have a 1GB DDR3 1333 MHz stick lying around.
I've read somewhere that it might not be good to pair up RAM sticks that are not equal in a computer (the set should be symmetrical), so if they were both 1333 MHz or both 1066 MHz I wouldn't be asking this. But since the 1GB one is faster, is it advantageous to install both and end up with 5GB of RAM?
This question relates to this one which says that the speed bottlenecks to the slowest rate, which I think would mean that they will both work at 1033. Does that mean that I should then install both RAMs?
Thanks.
You are running a 64-bit kernel right? – Ramhound – 2016-01-09T18:19:46.723
1What you read doesn't apply at all to your case. With only one 4GB module, that will operate in single channel mode. Adding a mismatched RAM module will also operate in single channel mode. There's no performance degradation. – sawdust – 2016-01-09T18:58:41.047
@sawdust Hey do you have any source on that so I read on it? – TomCho – 2016-01-10T16:06:28.950
@TomCho -- What you read was describing the requirements for dual (or triple) channel operation of memory. See https://en.wikipedia.org/wiki/Multi-channel_memory_architecture
