I've got a w510. On Lenovo's site it says that it's capable of dual channel. i've got 2x2GB right now in my system at 1066. i ordered 2x4GB at 1066. my question is
will i still be able to run dual channel?
and if so, how do i arrange the ram being that two slots are in the back and the other two are on the other side underneath the keyboard.

yes, i think you have to arrange the same ram in ram slot 0 & 1, and 2 & 3.
Use the HWinfo to find out whether the ram is running in dual channel.

yes that is correct. If you are unsure just use HWinfo (free download) to check.

Thanks for the replies.
I downloaded HWinfo and checked where the installed ram is and apparently Lenovo has it setup where the ones underneath the keyboard are 0 and 2. so i'm assuming I have to move one of those to a bottom slot?
or can i keep those there and just install the new ram in the bottom?
Edit: Nevermind, I ran CPU-Z and it says i'm running singlechannel currently. So I guess I do have to move a ram to a different slot to enable dual channel.

if you don't change the ram order to make them pair up properly then you won't get the dual channel benefits.

Yeah I figured since HWinfo said that they're currently in slots 0 and 2.
So I guess when my new ram comes in tomorrow, i'll hopefully pair everything right the first time. i'm assuming that slot 1 is directly underneath slot 0 and slot 3 underneath 2?

The hardware manual refers to them as "Slot 0 and 1" in both under the keyboard, and on the bottom -- no information in the hardware manual on pairing.
Let us know what you find, as I have 2x2gb sitting idle to install (was paitently waiting to confirm 100% my system freezing was resolved first, I think I'll call it a pass).

Ram came in this morning. got lucky on the first try with getting it to run dual channel.
when i opened the ram slots on the back of the pc i placed a a 4gb stick on the left side.
then i lifted the keyboard for the other ram slots and they're placed on top of each other. i took the one on top out and placed a 4gb stick in there. then i placed that 2gb stick that was there and placed it in the only slot remaining. booted my pc and on the start up it said it was installing some stuff and something about dual. and then to make sure i checked cpu-z and it showed i was running dual.
this helped a bit on how to install the ram
went from a 5.9 to 7.2 on the windows index score. now my lowest is the harddrive which is at a 5.9. probably going to wait until SSD becomes a lot cheaper to get one.

Thanks for this! I had no idea that you had to pair chips in opposite bays (why oh why didn't they just make it simple and put the similar chips in the same spot?)
I'm now running dual channel with 4 x 2GB DDR3 patriot branded chips.
I went from a 5.9 to a 7.3 on the windows rating.
