The problem with that is the amount of money CL6 1600MHz RAM would cost is not worth the gains on a 5 year old platform.
With DDR3 phasing out, it wouldn't be worth getting for your next platform either, unless you go FX series, or socket 1150 intel, which seems pointless right now.
CL8 and 9 do just fine for me. You may see some max FPS increases to the tune of 2 or 3 FPS with lower timings, but min and avg may not even be impacted.
I've tested 1333 CL6, all the way up to 2000 CL10, and so far 1800 CL9 has given me the best bandwitdth, lowest latency, and hardly any difference at all in notable FPS performance.
I also found that running over 2.9GHz NB gave me a performance hit, so it is NOT always the case that higher NB gives better performance.
It is actually relative to the CPU and RAM speed. For 4GHz the sweet spot for me is at 2800+ usually. For 4.2, it's at 3GHz but I can't handle the temps.
I also noticed that 2750MHz NB does better with lower RAM and tighter timings, while the 2925 I run now performs better with the 1800MHz RAM.
I have done A LOT of testing and verified all of this for certain. When you run a chip this old, you get plenty of tinker time
Still love my thuban too! Goes hard in every game still, and never tops 80% usage even in the newest titles.
