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!

leave the bus speed at auto. For me setting it at 200, or anything other than auto, has caused instability. When at auto mine reads at 200.63 in CPU-z. Leave CPU LLC at auto too, both. i dont remember off the top of my head if hpc mode has an auto setting but if it does set it to auto. Are you setting anything in the RAM timings? go into dram timing control and make it auto.

Once youve done all this ^
toggle Dram voltage between auto and 1.5 manually.

I can post a couple of my configs for you if you want, i have a 4.3, 4.4, and a 4.6 stable profiles saved, i think

That might be the limit of your chip, depending on its age, quality silicon used, factory it was made in, etc. Not every chip is the same, and those who can get a stable 4.5 are the lucky ones. At 4.2 you might be better off running it at stock? 3.5/4.1 "turbo", right?

anyways i understand the determination that comes with trying to achieve that perfect overclock, so this will probably be of great help

Thanks for the reply. Turbo is in no comparison to running it on all 6 cores at 4.2ghz. The way AMD turbo technology works is it only boosts a few cores for a couple of seconds when needed. I have my cpu running at 4.2ghz on every core 100% of the time, not just a few.

What is your CPU temp on full load? U could up the Vcore in increments and see if it stabilizes?

46'c. The reason I stopped at 4.2ghz was because 4.3ghz failed at 1.42v on occt. That means that it would have taken at least 1.43v to become stable, which to me, didn't seem worth it for just a 100mhz increase. It seems like continuing with multiplier only is a no-go. However, after reading about other people achieving better clocks by mixing the fsb and multiplier, I thought I could push it a couple hundred or so more....

Gaming performance overall is good but not perfect. I might be wrong but it seems to me that a 4.2ghz 6 core cpu paired with a r9 280x should have no issue gaming at 1080p while maintaining a frame rate of 60fps. While most of the time it does, I still get fps drops in certain games(sleeping dogs, arkham origins, bf4, skyrim and some others).
I can't help but shake the feeling that I can get a little more out of this rig without spending that much. Should I focus on raising the NB? Currently my NB and HT are set to 2200mhz in bios. What's a good voltage for NB at 2400mhz? Also, sorry for all the questions but would upgrading from 1333mhz ram to 1866mhz be worthwhile? Yes, I've seen the benchmarks between the two but would it help me get better overclocking performance?
Update: Solved my performance issues and I am now satisfied with 4.2ghz. I solved the fps drops I was experiencing by enabling HPC mode in bios.

The CPU needs more overclocking and then the gpu will match it better. Have u been upping te voltage everytime u up the multiplier? I'm at 4.6 ghz with voltage set tob1.4125. I get 4.4 at 1.38. I've seen this before...voltages the 6300 likes.
4.2 ghz - 1.33/1.35 v
4.4 ghz. - 1.37/1.38v
4.5 ghz. - 1.4/1.42
4.8 ghz - 1.45 max

U only need to up the voltage after u pushed the multiplier too far. Say at stock u up the multi but don't touch voltage and get 4.3 ghz. U keep upping the multi one bump a time and run a stress test like prime 95 in between each bump. When u finally fail the test u no u need to bump the voltage up one. Then test again. Repeat this proccess until you find ur Max OC...just make sure to monitor temps on hwmonitor WHILE running prime 95 (worker windows must be at a min prioritu of 8). The temp will ultimately be your limit here.

Thanks but I am well aware of the basics of overclocking. I always raise the multiplier first and stress it. If it passes, I raise it again. If not, then I raise the voltage a little and retry. That being said I was able to get it up to 3.7ghz on stock voltage. My voltage is at that because any lower and it would fail a stress test on OCCT.

I've seen those voltages online hence the reason of my frustration with my oc and suspicion that I have been missing something. I can't get my cpu stable at 4.2ghz with anything less then 1.39 even with llc enabled.

can you take some screenshots of your BIOS tweaker page? or at least copy down all your settings and post them. Im assuming you have spread disabled, c6 disabled, turbo obv disabled, svm can be off and hpm master mode leave at auto. Ive managed to get to 4.6ghz with 10 degrees C of headroom still at prime95 small fft test load. Hyper 212 EVO as well, is your CPU cooler seated right? did u try cleaning it off and reapplying paste?

No prob, and thanks for taking the time to try to help. Temps are within safe limits not exceeding 52 degrees on OCCT. Here are some pics of what I have so far in bios:

Well I originally had llc set to auto and I had worse results then I do now so that's not gonna work. I have HPC mode enabled because it has surprisingly helped a lot with fps drops. I only enabled that after I reached my max stable overclock so I know that's not effecting anything either. My ram is set to defaults (9-9-9-24 1.5v) nothing is tweaked there.

My performance is very good at the moment to be honest. HPC mode helped with fps drops not really stuttering. What helped with stuttering and micro-stuttering for me was upgrading to windows 8.1 from 7. Windows 8.1 has native support for the fx chips and is better optimized for them. As for batman, I had stuttering too before. Did you try adjusting the pool size in the ini? That really helps.
If you wouldn't mind though, could you post screenshots of your bios setup?
Performance for me isn't that bad, I get a very smooth experience with most of my games. I am however, open to suggestions if anyone has anything to add so I am leaving this topic open. Obviously if there is something that I can do to get more performance, I am all for that. By the way what is the timings/speed of your ram?

Hey reporting back here. I just changed my bus speed to auto and wow! What a difference in speed I have no idea why that makes such a difference but thanks! I should also mention I also changed the CPU core activation to manual and set them to all enabled. I'm not sure which change made the difference or if it was a combination of both but I'm loving the speed here. Will try stress testing later on to see if I can get higher but even if I don't, it's really nice now.

wow, will have to try to core activation thing!! I have mine at auto now, but yah for the fsb ive found this board does not like that fiddled with. Dram timings are set to auto, since when I set them to what the RAM asks (slower pair is cl9-9-9-24 I think) on the package it fails. When in auto, CPUZ reports it at like 11-11-11-37 or something like that which to me is weird, but performance has been pretty good.

Performance is good at 11-11-11-37? What is your ram frequency? I'm going to try stressing my cpu again at 4.3ghz while trying different things that you mentioned. I'll report back later on with results, if any.

I tried setting the dram to auto which gave it 11-11-11-28 timings for some reason. Set the fsb to auto and ran a stress test with a multiplier of 21.5(4.3ghz). Failed at 1.39v and 1.4v as well....🙁
Any other suggestions? The thing is it went a whole 1 hour and 40 mins before failing so it seems almost stable.

Reporting back with some good news. I managed to pass a stress test at 4.3ghz with 1.41v. While that is not the best voltage, it is still within limits and better than last time I tried 4.3ghz. Temps don't go over 52'c so I still have some headroom. Going to try for 4.4ghz later on. I'm not sure how I feel about this overclock. I did get 4.3ghz stable but at the cost of loosening my ram timings when setting them to auto. I don't think running my ram at such loose timings is worth it for just 100mhz so we will see if I can get it any higher.

For some reason my cpu defaulted at 1.36v. That was the auto voltage that was set for me at stock and it seems much higher then everyone else. At first I couldn't see why everyone was telling me my oc wasn't so great. I mean I only raised the voltage .03v from stock and raised the clock speed an additional 700mhz. It wasn't until after I saw those voltages everyone was using that I realized I had a lemon.
I'm going to shoot for 4.4ghz and so on later on. Like I said, seems silly to loosen those timings just for 100mhz so I am going to keep going and if I can't get it any higher, I will revert back to 4.2ghz with my default timings. After I get it stable at 4.4ghz-4.5ghz I will gradually tighten the timings back towards the original until it fails.

I am now at 4.4ghz and stable! I got it stable at 1.43v....not the best but not too bad. Surprisingly performance is pretty good even though the ram timings are loosened. I might shoot for 4.5ghz or I might overclock the NB instead. Any tips on getting the nb stable on this board?
