New to the community. Thank you in advance for your hospitality and assistance.

First build since 2008. Replacing an AMD FX-9950 Black, OC'd @ 2.9GHz (stock 2.6GHz), been OC'd since 2008. Running Win XP 32-bit (needless to say, it's time)...

Which is the better way to go using a Gigabyte G1-Sniper Z97 and a i7-4790k? ...

Each of the following G-Skill Trident X memory modules falls within my budget and the goal is maximum performance for a variety of applications.

(2x) F3-2400C9D-8GTXD vs. F3-2400C10D-16GTX (16 GB memory total, price no object in this specific case).

I.e., given identical frequencies, is it better to go with:
2 modules, 8 GB each, CAS 10, timings 9-11-11-31 OR
4 modules, 4 GB each, CAS 9, timings 10-12-12-31? (never mind the fans, both are rated @ 1.65v)

For this CPU (i7-4790k) would either make a noticeable difference on the memory controller (MC)?

What about having to access 4GB on a module vs. 8GB on a module?

Other than increasing total memory count, what advantages does having 4 DIMM slots have - especially if you know that you are not going to max out memory (not going to use 32GB) - i.e., does using 4 DIMMs open up 2 other "channels" which help data to "flow" or does it bottleneck at the MC?

Thanks again for any light any of you can shed... Peace.

Best solution

2x8GB - gives you tighter timings and less stress on the MC (memory controller) with only two sticks (ever, ever so slightly also only running the the signals through 2 pipes rather than 4... The Tri 2400/10 sticks are great, have a full 32 GB set in my IB build...and no there is no advantage to 4 sticks over two on a dual channel mobo, unless going 32GB - and having more DRAM
