AMD 1600 vs 1866 for overclock - Page 2

post #11 of 16
7-8-8-20 isn't tight enough @ 1600? :thinking.gif:
'Cause that's what my Samsung RAM does tongue.gif
1333=6-6-6-18 easy
1066=5-5-5-15
1866=9-9-9-24
2000=9-10-10-28

It's pretty decent, but PSC and BBSE will still beat it, and of course Hypers.  Where that samsung really shines it with high frequencies (2400mhz - 2900mhz) on Ivy and Bulldozer.

 

I'd say just get a gskill psc kit that does 1600 7-8-7 and set the timings manually to 6-8-6 at 1700mhz or something like that.

Independent testing by Tom's Hardware, AnandTech, X-Bit Lab's and OCN's "damric" have shown that at or above ~1333 MHz. there is no significant increase in real application performance with tighter latencies or higher frequencies as DDR3 RAM is not a system bottleneck at ~1333 MHz.or higher. Llano APUs are the exception and can benefit from higher frequency RAM. Synthetic benches will show gains but real applications rarely show anything significant.

In addition as the RAM frequency increases one clock cycle becomes less and less so reducing the latency has less impact than at slower frequencies.

Only you can decide what works best for you. Deneb CPUs will typically run RAM up to ~1600 MHz., Thubans up to ~1800 MHz. and FX CPUs up to ~2400 MHz.

I always recommend that people Buy What Makes Them Happy.
