The AMD FX-8320 remains stable under the present overclock settings.
The AMD FX-8320 remains stable under the present overclock settings.
Hello,
I hope this isn't a silly question, but I just wanted to confirm I'm not damaging my CPU or motherboard.
Recently, I chose to overclock my CPU slightly because I was experiencing low frame rates in certain games. My CPU was running at around 100% while the GPU (GTX 1070) was only at 60%.
I adjusted the voltage to +0.0125... and set the clock speed to 4200MHz, with a CPU Current Capability of 120%, a CPU/NB Current Capability of 120%, and DRAM Current Capability also at 120%.
These changes were made following this guide: http://www.overclock.net/t/1348623/amd-b...otherboard.
However, when I tried to modify all the settings, my PC would sometimes fail to start up or load the default BIOS profile, and the temperatures were too high.
I ran an AIDA64 test for two hours and recorded a temperature of 62°C. I've attached some images if anyone wants to review them:

Could you let me know if there are any other settings in the BIOS I should adjust, since I've only changed the clock multiplier before? Also, my motherboard is an M5A99x Evo R2.0.
Overclocks focus more on the method and precise temperature control than on quick numbers. On the 8320, you might still have 100-200Mhz left before temperatures rise too high, though that may not be the case. 4.2 is a typical outcome for that chip, and I anticipate the board will reach roughly 90% of its full potential (it's a solid board, but not outstanding). This guide also provides detailed FX instructions: http://www.amd.com/Documents/AMD_FX_Perf..._Guide.pdf
It seems your CPU might have some extra overhead for OC. The value .0125 is minimal, and 62C is quite low. You should be able to extract significantly more performance from it. I’d stop around 80c after two hours, not 60! What voltage should you aim for? Should you increase it gradually one step at a time? Also, do you need to adjust anything else? I was concerned about the temperature because the guide mentioned these limits: CPU Core - 62°C, CPU Socket - 72°C, Voltage Limits - 1.55v.
It seems your CPU has a bit more overhead for OC. The value .0125 is minimal, and 62C is even less. You should be able to extract significantly more performance from it. I’d stop around 80c after two hours, not 60! Since it’s an AMD chip, look into the research—it should throttle near 65C, so at 62C it’s right at the limit.

Geekwad :
Overclocks are much more about the process and carefully monitoring temperatures, than hard and fast figures. You may find on the 8320 that you still have 100-200Mhz left before temperatures really take off, but you may not too. 4.2 is an average result already for that particular chip......and I'd expect that board to only get about 90% of the available performance possible (it's a very good board, but not exceptional).
This is also another thorough FX guide:

for some of the finer tuning details on that platform to get as close as possible to your top end.
Thank you so much for the guide, and thanks everyone for all the help. I managed to push it up to 4.3GHz and keep it at 62 although it doesn't go as high when i'm gaming, The only reason I wanted to OC was because in Dota 2 with ultra settings I will occasionally get fps drops but now i never get fps drops.
I don't know if i messed up when I was installing my cpu fan, I might have put like a bit more than what was shown in the video but it was like 1/4 of the tube and I have a coolermaster 212 which people were saying was a good cpu cooler for overclocking but can someone tell me if this is the expected temperature or have i made a mistake?
and it seems like that the cpu fan only goes up to around 1000rpm, and never above that, do you think there is something wrong with it?
also just want to make something sure, when people talk about the CPU temperature do they mean the socket temperature or the Core temperature?
my core temperature is always around <40C when gaming, I will feel really stupid if this is the temperature that i'm meant to be monitoring.
Thank you.
I reached up to 4.4GHz and lowered the temperature to 54C. I switched the fan to manual mode and adjusted the max temperature to 60, which caused the fan to spin at over 1300RPM during a 2-hour test, maintaining the 54C level.

+.0125 is minimal. 62C is almost negligible.
You should be able to extract significantly more performance from your CPU than that.

It’s an AMD model, so do some research—it will throttle to about 65C, which means at 62C it’s right at the limit.
Could you let me know what the recommended idle temperature should be? My machine stays between 35-42°C when using the browser or doing light tasks. People say it should be under 30°C during idle, but I never reach that. I assumed all cores were running at 4.2Ghz constantly, so I switched to balanced power mode in Windows, which now downclocks when not gaming, but it still hits around 40°C during idle.
