My FX-6300 is overclocked to 4.5Ghz stable. While playing games that are intensive like GTA V, I notice that my temps go pretty high. I took a screen shot of what my temps were when I was in a session of GTA V. Look at the max temps in HWMonitor, are these safe? You can ignore CPU-Z.

I didn't mess with the CPU-NB Frequency, I just messed with the Multiplier and the Voltages. Left all power savings enabled, and I enabled HPC Mode, and disabled Turbo Boost.

I still think them temps are a little high, but what do I know.

What temp are you concerned with? Using 3rd party software like HWM, one is never quiet sure which temps are being recorded by "system" and "tmpin2". If those are NB/SB temps, they are fine. If it is socket temp, still fine. As to the CPU temp, one can only assume that is an average of all three modules or maybe all six integer cores. Low 50Cs for CPU or core temps at load is great. If that is idle, not so great.

If you want another way of looking at it, run AOD: http://www.techspot.com/downloads/4645-amd-overdrive.html
In place of the CPU core temps, it will display thermal margins instead; the higher, the better for TM. That is the temp until the CPU reaches its tjmax. I like to stay below that by double digits at max load.

I actually just fiddled with the overclock today, and I lowered the voltage to 1.41250 with LLC on Medium and now I get anywhere from 1.392v to as high as 1.428v. My temps have gone down a lot, they barely reach the 50's. I ran a quick P95 Blend test for around a half hour to check if the voltage drop was stable, and it seemed fine. I'll continue monitoring my temps and voltages with HWMonitor for the next couple of days. Everything seems stable now though. Anything you need to ask or tell me?

You'll find typically the default frequency for the CPU-NB is ~2200, but many overclockers have found that their overclocks are more stable, and generate less heat, when their CPU-NB frequency is ~2400 (or 3x the DRAM frequency of 800 [x2 = DDR3 1600 RAM]), and the HT Link is ~2600, as well as having the RAM set to 1.5v or less (including adjusting the frequency/timing of the RAM if it is a 1.65v model down to the SPD settings).

This drops the stress on the IMC in the processor which stabilizes the overclock.
