My motherboard has quad channel memory compatibility. There are 8 memory slots in all:
- 4 slots are black
- the other 4 slots are white.
I currently have 4 memory modules of 1 GB each in the 4 white slots. That leaves me with 4 free memory slots.
My question is: can I put 4 memory modules of 2 GB each in the 4 remaining slots or do I have to use modules of 1 GB all over?
FYI here is the output of lshw:

2Check your manual for supported memory configurations. – Ramhound – 2012-11-05T10:41:31.270
Hello Ramhound. I am not with you: do you mean it depends on my motherboard? My question is a general question about quad-channel compatibility. Can someone please reply to it? – balteo – 2012-11-05T10:48:20.337
1Some memory configuration have specific speed requirements on some motherboards. This isn't and CANNOT be a general question, because those requirements, are all spelled out in the manual. My motherboard for example only supports 8GB in a specific configuration, otherwise, it only supports 4GB. The output you provided us also doesn't tell us what motherboard you have, so its not that helpful, you can easily answer this question yourself. – Ramhound – 2012-11-05T11:27:59.720
