Help overclocking my fx 6300 with multiplier and FSB

[tensai27]

I've already managed to overclock my FX 6300 up to 4.2ghz through the multiplier. I have the NB and HT set to 2200mhz and LLC is enabled. I raised the voltage up to 1.39v(stock was at 1.36v). It's a stable overclock and has passed several hours on OCCT.
I have read on forums that a lot people were able to get higher overclocks with lower voltages by doing a mix of multiplier and FSB. I don't really have any experience with overclocking through the FSB, as I have always preferred multiplier due to it's simplicity. I know when you mess with the FSB, it changes a lot of other values such as ram frequency.
I'm just really unsure as to where to go from here. I have reasonable temperature room. Stress tests at 4.2ghz only get me up to 46'c. Should I back off the multiplier and raise the FSB? Should I overclock or under clock the ram? How about NB/HT?
Here's my specs:
FX 6300 @4.2ghz w/ hyper 212 EVO
ASUS M5A97 r2.0
1x 7200rpm hdd
8gb ddr3 1333mhz (4gbx2)
MSI R9-280x
SeaSonic S12II Bronze 520W PSU

4.2ghz isn't that bad but I'm hoping to be able to reach 4.4-4.5ghz to help reduce fps drops in cpu intensive games. I appreciate any assistance. Thanks!

havnt had too much luck with that ,i just leave the nb alone

Same here. I tried 2400mhz but kept failing with all kinds of voltage so I left it at 2200mhz. I might shoot for 4.5ghz but I'm not sure if it's worth using 1.45v (the voltage I will most likely be using based on the pattern)for. Especially with llc enabled. I'm also going to try tightening my ram timings to 10-10-10-[something lower]. Thanks for the help in getting my cpu past 4.2ghz even if it isn't at the best of voltages, it's still better than the last time I tried it.

Beezy, did you try tightening your timings after?
