After a successful overclock, does the CPU temperature increase slowly in the BIOS?
I achieved a successful overclock of my Athlon x4 860k to 4.3 gigahertz. Although the P95 stability test showed no warnings or errors, I reduced it to 4.1 because of temperature and voltage issues. At 4.3GHz the peak voltage reached 1.450 plus, with temperatures exceeding 61°C. At 4.1GHz the voltage stayed below 1.420 and temperatures peaked between 58-60°C without surpassing them. While idle in Windows, the CPU temperature dropped to between 33-36°C. However, in BIOS, without any action, the temperature increased every 5 to 15 seconds. Maximum temperatures reached up to 60°C in BIOS. Anyone have experienced similar issues? Or is this just normal behavior?
Here are my specifications:
CPU: ATHLON X4 860K
MOBO: A88XM-E45
RAM: GSKILL 2133C10D GXM
VCARD: SAPPHIRE R9 380 ITX
COOLER: COOLER MASTER SEIDON 120V PLUS
I wouldn't stress too much about those uncertain temperatures. Look at what they are when under load and if they're a comfortable temperature for your CPU, you should be fine. It's odd they rise to 60 degrees when idle. See what voltages are available and whether your setup is configured to maintain that voltage consistently, which might explain the issue.
It's quite a lot of voltage for such a water cooler, so it makes sense it would get warm up this much.
The quick temperature increase consistently occurs when you boost the CPU's working frequency. The more demanding the clock speed, the greater the power needed from the core. It’s no surprise that heat builds up rapidly at some point. Even with FX-based CPUs, you eventually reach a limit where the core voltage must be increased. This causes the CPU to heat up more quickly. Look at the maximum thermal capacity of a 860K processor. Before the CPU throttles, based on memory data, it’s around 80°C on a 860K chip. This suggests you should test the CPU under extreme conditions using Prime95 if you want to verify. Doing so could add another 15°C to 20°C to the CPU temperature.
It's unfortunate to hear that your motherboard lacks vcore adjustments in the BIOS. I attempted to use AMD Overdrive, but the system became unstable. It seems AMD Overdrive may not be compatible with your motherboard. I removed the AOD utility and the system became stable again. Your vcore range is between 0.900 and 1.420, which changes with workload. In Windows, temperatures stay between 32-36°C when idle and 55-60°C during games. However, the most concerning issue is the rapid temperature increase every 5 to 15 seconds in BIOS. This behavior isn't typical, and I'm unsure if it's normal. Would you like me to investigate further?
How much they are increasing, it's typical for them to rise slightly while in bios.
Hi djreedj... Your observations are correct. While running in BIOS, the processor temperatures rise steadily from a low idle range (28C-32C) to higher max levels (58C-60C), increasing by about 1C every 5-15 seconds. When you boot into Windows, the temperatures drop back to a normal range (32C-36C). Also, resetting BIOS settings to defaults prevents this temperature rise. This behavior is typical after CPU overclocking.
