Do I have to install RAM by pairs?

You don't need to install ram in pairs. You can install one stick at a time if you want. However, for the motherboard to work upon startup you have to install the first ram pair in the assigned slots. It's in the booklet that comes with the motherboard. If you install one ram stick and it's on the 4th slot but the 1st slot is vacant then the rig won't start up properly.

Nope, I ran it with 1 4gb dim And 3 mixed dims. Use whatever combo you want!

you always have to do it in pairs, if your looking to upgrade to 8gig you need two 4gigs two of these will upgrade you to 16 which is lightening fast.

No, this is Server Memory. I found out too late and I was beyond the return period. Now stuck with 2 sticks of perfectly good RAM that I cannot use.

Probably yes, I'm using one fan because the other one won't allow install the ram in the first slot for 1 or 2 mm, I'm using gigabyte motherboard.

I was unable to get mine working. I have a suspicion that this particular RAM needs to be installed as a matched pair.

Yes but you need two of them. Try Crucial 4GB Kit (2GBx2) DDR2 667MHz (PC2-5300) CL5 SODIMM 200-Pin Notebook Memory Modules CT2KIT25664AC667 / CT2CP25664AC667

Ram is ram. The only difference is the size. (Desktop,laptop) so you should be fine.

That combination is NOT listed in the manual as officially supported. This is the only 8GB supported RAM listed, http://www.newegg.com/Product/Product.aspx?Item=N82E16820233271

No. If you install this RAM with out replacing your 4 GB, it will bottleneck.

I haven't done it yet, but it shouldnt't affect your ability to upgrade your ram. If anything it will only help your performance.

You should use 2x4GB sticks to enable dual-channel unganged mode for better performance

You can install a maximum of 16GB RAM memory. The mother board has 2 slots.
