Okay so I am overclocking my FX 6300 and I am shooting for 4.4-4.5ghz. I am using the hyper 212 evo cpu cooler and the asus m5a97 r2.0 motherboard. I am overclocking my cpu to 4.4ghz at the moment and it is requiring an unusually large amount of voltage and before I conclude that I just got a bad chip I was hoping someone could point out if I am doing anything wrong or if there is anything else I could try to get it more stable on less volts.
These are my full specs in case it is relevant:
FX 6300 w/ hyper 212 evo
1gb 7850 overclocked to 1040mhz on stock voltage(1.138v)
7200rpm internal hard drive
Asus M5a97 r2.0
8gb ddr3 1333mhz (4gbx2)
SeaSonic S12II 520w
No optical drive installed
Here are some screenshots of my bios config thus far:

Thanks in advance and any help/insight will be greatly appreciated.
-edit: just noticed the ht link speed on two of my images conflicted but I have ht link currently set to 2200

Just checking back.

Glad you're getting closer to your goal. I can't blame you for being so cautious, especially considering this is new to you. :)

All the voltages in my OP are still below the max safe limit by a bit. So you should be OK as long as you don't exceed those and as long as you have good case ventilation/cooling.

I generally stop at 56c load temp or 1.475v, whichever comes first. That is well below the limit for this CPU, but I like to keep some longevity built in my overclocks. 😉

I just passed the 2 and a half hour mark on occt and still stable at 1.4v and 4ghz. I am doing 3 hour occt tests since all the failures that occurred after 2 hours happened before 2 and a half hours. Once I reach my max stable clock at my max comfortable voltage I will do a more extensive test (probably around 9 hours or so on occt just to be 100% sure) Now that I have most likely reached a stable 4ghz, what should I raise the NB and HT to after I finish this stress test?

3 hour occt passed. I think it's pretty safe to say for now that 4ghz is stable at 1.4v which is not that bad I guess since it's a 500mhz increase from 3.5ghz and stock voltage was at 1.36v. I would like to continue on but not sure if I should be raising the NB or not.

After you reach to the max stable overclock with good settings, start to rise NB frequency in the same way that you did with CPU multiplier and voltage. HT doesn't add significant performance to your rig above 2000MHz, so, keep it at those settings.

Would raising the NB increase stability allowing me to reach higher clocks or just improve general performance?

4.1ghz crashed 14mins in at 1.41v..🙁
Although I expected it, I had my hopes up.
Well here it goes at 1.42v....
What's weird is that I actually had a good 2 hours before on 4.1ghz....now that I think about it voltage might have been set to auto before which might explain it and also be quite embarrassing. :lang:

Depending on the board and chip, OC instability can be caused by a few factors.

To counter voltage/clock fluctuation due to features, disable:
AMD APM (Application power management)
C1E
C6
Cool and Quiet
Virtualization
Spread Spectrum
Core Boost

To counter instability due to FSB and IMC, give your HT and CPU NB voltage about a .050v boost. Should be around 1.150 and 1.250 for these.

To counter instability due to v-droop, if you have LLC calibration set that up to it's highest setting, usually in the 2.5-2.7v range.

These should help.

I was able to get my brother's FX 6300 to 4.4GHz @ 1.375-1.40v core using the above NB and HT voltage bumps, and also supporting DDR3 1866 at 1.520v DRAM. NB was 2200, HT was 2400. With the Hyper 212 EVO is stays in the 52-55c range under full load.

Worth noting: That is BELOW the stock core boost voltage of 1.425v. We got a REALLY good chip for his system, it clocks like a champ. Hope you have similar success. :)

Also worth noting: 4.4GHz @ 1.4v = 139w TDP. His Gigabyte 970A-UD3 board is rated up to 140w and has an 8+2 power phase with a VRU heatsink. Make sure your board has similar ratings or you will fry it trying to pull a high OC on these CPUs.

Thanks for the input. I already disabled all those features you mentioned before I started overclocking. I haven't messed with the NB or HT voltage but I will give that a try. As for LLC, I seem to only be able to choose between auto, enabled or disabled. I have it currently set to auto.

OK, give the NB and HT a small voltage bump. That will help stability a lot. You could start with +.025 first and go to +.050 if you need to.

CAUTION: I looked your board up and it has a 4+2 power phase.

PLEASE Check with Asus before you go any further to see if it can handle 140w TDP CPU pulling that much current. A fried VRU will kill your board, CPU and possibly the RAM and GPU if it blows up really badly.

Just to clarify, I have this motherboard http://www.asus.com/Motherboards/M5A97_R20/
not to be mistaken with the LE or EVO. It seems fine but I could be mistaken...

4.1ghz failed at 1.42v on occt 1 hour in. I'm thinking about upping the voltage on ht and nb but now you have me a little scared there. Googling now but not really seeing anything regarding whether or not it's safe.

Alright calling it a night(it's 2am here in Taipei). Appreciate all the help so far. I'll be checking back tomorrow. Hit a little stump here as I am unsure whether or not to continue my OC. Although it seems fine I am not 100% sure. If anyone has any info it would be appreciated. Thanks.

I'm back. I'll try continuing what I am doing until I reach ~1.45ish volts like originally planned. If raising the voltage on the NB/HT allowed me to reach a better stable clock at less volts through my chip, wouldn't that be better? For example: if I could reach 4.3ghz at 1.42v with a slight NB/HT voltage bump, wouldn't that be better than running 4.3ghz at 1.45v and up? Is it really that dangerous on my motherboard to raise the NB or HT voltage a little? Not sure if this helps but here is a picture of my motherboard. http://elmir.ua/img/146262/1960/1280/materinskaya_plata_s-am3_amd_970_asus_m5a97_r2_0_atx.jpg It seems like it's built well enough to take on a little voltage bump as long as I don't go too crazy.

Can you guess what Saint19 is going to Taipei for? If I said MSI would that give the game away?

I was able to run NB at 2200mhz without any issues. As long as it's safe, I wouldn't mind pumping slightly more voltage than stock on the NB to improve the stability of my OC provided that maddogfargo's claims are legit. If slightly over-volting the NB proves to be the secret to achieving better stability at high clocks then I'm all for it. How does leaving it at 2000mhz and raising NB voltage by .025v for now sound? Worth a try?

Alright this is cool. I got past the one hour mark on OCCT at 4.2ghz with 1.42v. I switched CPU LLC from auto to enabled. Left CPU/NB LLC on auto. Seems to have helped stability but added about 10c to temps bringing me up to 48'c while stressing. If this test passes I will proceed to 4.3ghz at 1.42v and report back on how well that does.
