Help overclocking amd fx 8350

Solution
1. have a good quality 500+W power supply.
2. Get a custom cpu cooler eg coolermaster hyper 212 evo
3. Get a better motherboard. The G45 only has 4+1 power phases and is only built for 125W max. Try a 990fx mobo eg ASRock 990fx Extreme 4 - 8+2 phases, 140W

The motherboard will keep you from getting past 4.3 probably. If you really want to overclock you will just have to tweak the settings you have in place... but settle for 4.3 or something close to it considering the voltage the VRMs can supply. Also hope your chip is binned from high quality silicon.
Turn off all power saving features, use the various guides on the internet, play with all your combinations of LLC etc, lower the stress on the IMC by loosening RAM timings, combine all the tricks to maximize what you can get within thermal limits.
A new motherboard switch with windows 7 OEM will mean you need a new Windows key too...If this isnt an issue a motherboard change to a Gigabyte Ud3 rev 4 or later (990 chipset or 990fx) would be best. I would avoid ASUS personally because i and many other struggle with a seemingly ASUS only problem...SOCKET HEAT. the socket temp is usually 20C higher than my package under full P95 load or IntelBurnTest and the only solution is extra fans behind the socket. Generally 50C package with a 69/70C socket.
Running an M5A99FX PRO R2.0 with an FX 8320 + HYPER 212 EVO. 4.2 Ghz @ 1.275V Cool n' Quiet/C1/C6 enabled.

where do you get that info? not saying you're wrong i just want the source if you have it. Everyone always says for the FX line 62C MAX for package and 72C MAX for socket. The socket reading comes from some sensor built into the motherboard. I suspect my boards sensor is located near the CPU socket by the DRAM dims because i have a dead pocket of hot air (the bottom of my cooler being the 'roof', with my Gskills forming a 'wall' next to it.)
Core temps are calculated by an algorithm on the FX chips that doesn't become accurate until it hits 40C or higher. that's why people say "my FX idles at 8 or 9C" when that would be impossible because the room itself may be 18C (the Package will always at minimum be the ambient temp of the room). the Socket temps on the other hand are from a real sensor, you can even measure the heat output yourself with a special device that you press onto a intended location on the motherboard for that purpose (if the sensor is believed to be inaccurate or faulty this will probably be done at a quality repair shop)

i realize that. I originally had an M5A97 PRO R2.0 and i loved it, 4+2 power phases an i OC'd my FX 6300 to 4.6 on it, and my FX 8320 to 4.0 solid on it. (the EVO has the 6+2 phases).
So when i wanted to overclock further i thought it made sense to get 50% more VRM power (6 phases over 4) and i would OC to the high heavens...
Oh how i was wrong, most boards sockets usually start around 10-15C above package temps. This one hangs around 15-20C ,and for Overclockers that makes a huge difference.
Thats why i recommend something like the 8+2 power phase boards from Gigabyte (newer revisions without VRM throttling issue).
The sliver lining here is i didnt think about my Windows 7 key being tied to the motherboard when i impulsively bought my new M5A99FX off newegg and it shipped to my house. Fortunately going from an ASUS board to an another ASUS bard posed no problems reactivating my windows license.
sorry, 62c is apparently the max core temperature (not 100% sure tho)
ive myself exceeded socket temp of 75c and it didnt throttle or shutdown
e: atm i own an m5a97 r2.0 (4+2 power phase) changing for m5a99fx pro r2.0 (same as you
)

and i think that's because AMD doesn't want us truly hanging around unsafe temps, so they give us some headroom to ensure no one truly damages their chip. Generally a CPU can be in the 80's or 90's before it will throttle or shut down. Socket can get high too. At this point if no throttling occurs the concern becomes longevity of the components. Running metal at high heat and letting it cool down (on shutdown), and repeating daily, will cause it to brittle and break (a capacitor for example) faster than if you stayed in the recommended temps.

Well what OS do you have? if you are trying to reach a higher overclock dont go with the board i have...If you can get a different board with 8 phases that would be better.

yes and while the CPU is happy and receiving plenty of voltage, the socket temp will hold back the CPU from going any further. You may be best off doing what you are doing because it sounds like what i did, and i was able to keep my windows 7 OEM. If your Windows is NON OEM get 8 phases...or dont listen i dont care lol.
just want people to learn from my mistakes. think of it this way, i will NOT be purchasing a liquid cooler for my CPU because i know while the CPU is good (4.2 Ghz @ 1.275V stable is pretty good), the socket will hit 72 before i can reach 4.3Ghz or higher. In a different motherboard though, like an 8 phases ASUS/Gigabyte, i think i could push much further even with my 212 EVO (and 4 cougar fans, good airflow and exhaust)

thats good if its full load. The thing with liquid coolers and a lot of air coolers is while they do a great job of drawing heat away from the CPU itself, they dont provide any extra airflow to the VRM or socket area (facing head on ideally). This widens the gap between core and socket a bit. Their only means of keeping the socket cool, is by keeping the CPU cool.

no and no, windows 8 can be moved from any mobo to any mobo with no restrictions, as long as its activated only on one PC at a time. Windows 7, while i find it better all around, does not have this leniency. the OEM liscenses of Windows 7 are tied to the motherboard they are first installed to, forever, permanently. its tough to get that license moved to a new board and ultimately hinges on luck.
Always OC from the BIOS, software is not stable and will never be as good as long meticulous manually entered settings and stability testing.
