Ram speed effect overclocking?

[tensai27]

OKay, I know this has been asked before and I realize that the difference in performance between 1333mhz and 1600mhz is minimal. Here's the thing, I have the fx 6300 and the m5a97 r2.0 motherboard and I have been struggling to get it stable anywhere past 4.2ghz. From what I have been seeing on the web, everyone who has reached decent overclocks with my combo has had 1600mhz and up. I have never once seen anyone with 1333mhz report back a decent OC with my board and chip. It's seems odd but could it be that having faster ram improves stability on my cpu when overclocking past 4.2ghz? Thanks in advance.
Also, here are my full specs in case it is relevant:
FX 6300 w/hyper212 at 4.2ghz 2200mhz NB/2400mhz HT
Asus m5a97 r2.0
7200rpm hdd
8gb ddr3 1333mhz (2x4gb)
r9 280x 1100mhz/1550mhz
Seasonic 520 s12II bronze

Okay so I tried out 1333mhz with relaxed timings and it crashed pretty much instantly. The frequency is definitely effecting it. It looks like I would have to purchase 1600mhz after all if I want to run it at tighter timings. Question: if I bought 1600mhz with 9-9-9-24 timings, could I use those timings or would I still have to loosen them to keep my OC stable?

The timings being loose/tight shouldn't affect the OC at all, I would buy 1600 MHz with 8-8-8 timings personally as its not much more expensive(sometimes the same price) and it is a bit better. Just dont' buy 1.65v memory @ 1600 mhz as there is no need for 1600, they my CL 7 kits that are 1.5v
