Manufacturer ships 2+4GB ram

Intel claims that their newer chipsets (ie: Cougar Point and above) don't really care about whether there's asymmetry over the entire RAM space.  Dual channel will work for the portion of RAM that is actually dual channel, and only "upper memory" will be single channel.

i heard asymmetric memory sticks prevent memory from running in dual channel mode, but i have found some manufacturers ship laptops with 6gb ram in 2+4 memory sticks. So is it alright to keep them that way ?

Yes, it's fine.

They will work fine, but may be a bit slower(less than 5%). Some systems have it so that the first 4gb is dual channel and the last 2gb isn't.

Well I just wouldn't buy one then if you care. Tbh I would not even buy anything with less than 8GB today unless I would get something chromobook-like but I'd just go down to 4GB then anyway so :/ Sry if you feel this didn't answer your question becasue it didn't. I think you are correct on that thought. No dual channel.

you mean 5% slower than the speed i'm suppose to get in dual channel mode ?

Depends on the program, but its normally less than a 1% difference, with someprograms being around 5%, but the extra 2gb is much more of a improvemnt than the ram speed.

If they are from same architecture. Like some memory have 1600mhz and 1333mhz with same architecture. Then they will both underclock to 1333mhz just fine.

There are other exceptions to this. If you dont find all channels in cpuid then they are not compatible with eachother.

By architecture i mean same brand and almost same name and design.

I have purchased the new HP laptop with i3-7100u processor. The means i can put 8GB ram with 4GB ?
