MEMORY 2x4GB vs 8GB

*read before you reply

Regardless if i need 8GB RAM or not.. my question will be very specific.
Disregard the price too...

which is faster, 2x4GB DDR3 1600MHz or 1x8GB DDR3 1600MHz

I don't think you will find much in to be honest rapstar as long as the 2 x 4GB is bought as a pair it is likely to have come off the same batch in the production line.

Me I would go 8GB for starters and then 16 if I felt like it depends on what you are going to do with the machine. The 8GB will be very matched if you get my drift.

Think a bout one batch of yellow house bricks the colour will be very even and equal the next batch may be a shade lighter.

I just know from many fixes the mixing of brands for instance doesn't guarantee the same performance.

Actually, the 2x4GB can be faster then the 1x8GB because it will run in Dual-Channel mode while the single stick of RAM can only run in a single channel. What this means, the two 4GB sticks can be accessed at the SAME time.

Ok all yours logic.

nowadays dual chanel is around 0.5% performance difference. before it was around 5% (only memory intensive bench) that is not much too.
I would recommend 1x8GB less memory sticks less problems and more free slots for future upgrade.

check your mobo guide. if its a dual channel, you need 2 sticks in the appropriate slots.

At this point, I'd probably bring it down to cost. Are the two 4 GB sticks cheaper than a single 8 GB, or vice versa. If you put in two now, you'd have to replace both later on if you need to go to 16. Most people would have no need for 16 GB of memory for the foreseeable future, so this could be a non-issue for you.
