Can I upgrade half the ram?

My pc only has 6 GB of 1333 MHz ram, and I want to upgrade as it is starting to get bogged down whether gaming or using multiple programs and browser windows (I usually have at least 2-3 programs running, plus all the background stuff).

I have an i5, so pretty sure that's not the bottleneck, and it slows down more on non-gaming apps, so pretty sure gpu isn't bottlenecking me either.

My system has 2x 2 GB sticks, and 2x 1 GB sticks, all at 1333 (alternating 2gb then 1gb then 2gb then 1gb).

Can I replace the 1 GB sticks with 2 GB, and leave the original 2 GB? And if so would it be advantageous to use the highest speed the mobo would support, like 1600 or 1833 if it does?

Or does all memory run at the slowest speed installed?

If so, I would probably get 8gb of 4x 2gb sticks at 1833, or whatever is highest supported by mobo, will have to figure that out somehow.

Jst trying to get a little more performace without spending more money than necessary.

mixing ram is a terrible idea, as you can get ram at relatively cheap prices i would just buy a new set, the speed of the ram will not show much improvement be it 1333/1600/1833 whatever your mobo supports, id also get 2 channel ram so just 2 sticks as it can be harder for the mobo to use 4 sticks,
so 2 x 4gb sticks better than 4 x 2gb and don't worry too much about the speed just get whats in your price range
on a side note if your experiencing trouble its probably because you have different types of ram installed even if it is all 1333

It came from Dell with mixed ram, but good to know. So 2x 4 GB is the way to go, and speed doesnt really matter? So no reason to get 1600 over 1333? Thanks

no real reason to get 1600 over 1333, no difference that you will notice it won't improve fps in games or anything like that, with the way ram is priced if you have a paticular budget like say £40-£50 then you can pretty much pick any speed you want

Ok, I'll just get 2 sticks of 4 GB 1333 then. Last question, I know the ram has to be placed in non-adjacent slots for dual-channel, but does it make any difference if it's installed in slots 1 & 3 or 2 & 4? The mobo is made by dell (socket 1155 i think?) if that makes any difference.
