Bad Cpu voltages AMD 6300 (Help please)

this happens because of the turbo of your cpu
in turbo it runs at 4.1ghz per core and therefore more voltage is needed

amd is known to overvolt their cpus a little on auto settings so if you don't run it with the stock cooler i would recommend to disable the turbo core feature and overclock it to the speeds of turbo with stock voltages (1.325v)

overclocking a fx 6300 is pretty easy because it comes with an unlocked multiplier

to overclock, boot into your uefi (with asus and most other motherboards, hold the "del" key after starting your pc
then go to advanced settings and be sure you are in the ai tweaker menu

change the ai tweaker tuner to manual and set following values:

AMD Turbo CORE Technology - Disable
CPU Bus Frequency - 200
PCIe Bus Frequency - Auto or 100 (which is default)
CPU Spread Spectrum - Disable
PCIe Spread Spectrum - Disable
EPU Power Saving Mode - Disabled

CPU & NB Voltage - Change from Offset to Manual
CPU Manual Voltage - 1.325v
CPU/NB Manual Voltage - 1.187v

to gain your frequency you wanna have, just mutlipliy your cpu bus frequency (fsb, default 200) to your multiplier
your bus frequency is 200 and your default multiplier 17.5 = 3,5ghz

to overclock know to your turbo frequency, just increase the multiplier, so that 200 * x = 4,1 ghz
so change your multiplier to 20.5

save the setting and reboot

im not sure if the cpu voltage of 1.325 is enough, if your pc boots, you are fine first, if not, slightyl increase your voltage e.g. to 1.334
if you successfully booted, you should/must test for stability and temps know, so get a few tools called "prime95", "cpu-z" and "hwmonitor"
this tools are all free

with cpu-z, you can check your cpu frequency and voltage
with hwmonitor, you can see your cpu temps
with prime95, make a blend test

this blend test lets your cpu calculate pi numbers and you will see, how the temp is going up (100% cpu load)
always keep an eye on your temps

your safe temps are:
max. safe socket temp: 70° C
max. safe core temp: 62° C

let this test run about 15min and watch out, if you dont reach this safe temps

if a test should fail (prime95 will write "worker stopped" at the core) or you get a bluescreen, slightly increase your cpu voltage again, but only, if you have not reached your max safe temps yet

if your temp is too high, slightly decrease your multiplier (e.g. to 20), which will result in 4ghz and test for stability with prime again
always keep an eye on your temps

i heard of people overclocking the fx 6300 to 4.5 ghz on air, so with 4.1 you should be fine if you don't have a really bad chip (overclocking always depends on your cpu too, every chip is different in this terms)

a whole load of information, i know, i hope you can understand it
if you have any further questions, feel free to ask

p.s.: about all the settings listed above, it does exist a pretty good overclocking guide for piledriver cpus (like yours is):
http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

this is leaned on asus motherboard, but you can easily adopted to other ones if you dont have an asus

glad I could help

yeah, 4.4 to 4.5 should be possible, depends a lot on your chip and which voltage you need therefore
due to the fact the amd fx cpus tend to get really hot I suggest you use some kind of water cooling like the corsair h1001, especially for 4.5 ghz
´
i got my fx 8320 (also 3.5ghz stock like your fx 6300) running at 4.2ghz stable on air (noctua nh-u12s), I wouldn't go any further on air cooling
