No, I did mean that the RAM speed goes down. The performance drop is probably low but, at least for my AMD CPU setup, the RAM speed clocks down for every module you add. It may not apply to Intel boards at all.

Ok I did wonder why you said RAM speed. It doesn't mention it in the specs on Asus's web site, I'll have a look in the manual to make sure, thanks for the heads up though.

Ah, I forgot, in some setups the RAM speed goes down when you use more RAM slots so it's probably worth buying one decent-sized module if you're after some raw performance at times.

Having only one big module instead of two slightly slower ones will give you noticable performance impacts, since the memory controller can't use the dual-channel feature. The memory controller can handle two modules just as fast as a single module, usually the downclock of one step only happens when you use two modules per channel (at least on AMD CPUs, I couldn't find reliable data for intel CPUs on this, but I assume that it is the same for them).

Sorry, TobiSGD is of course correct.
