FX6300 overclocking issue
FX6300 overclocking issue
Hi
I'm looking to make the most of my FX6300 setup. I've installed a Hyper EVO 212 cooler and two case fans to enable overclocking. My system runs on an MSI 970a G43 plus motherboard. I've set the clock speed to 4100Mhz and adjusted the core voltage to roughly 1.43 to 1.45V for stability. I use Speedfan to monitor temperatures and P95 for stress tests. Speedfan and MSI Command Centre show similar CPU temperatures—around 38°C under light load, rising to about 55°C with P95 at full load (Temp 1 on Speedfan).
During stress testing, the PC remains stable at 100% load, showing no errors or reboots. However, after approximately 7 minutes it suddenly shuts down completely. When this happens, the CPU temperature is around 55°C, but the Temp 2 reading on the speed fan climbs to about 124°C before the shutdown. This seems consistent with what I've observed before. It appears that reaching a certain threshold on Temp 2 triggers a hard restart.
My concern is understanding what Temp 2 represents and why it causes such a high reading. Could anyone help clarify this issue? It would be a shame to hit the CPU limits, and I can't push overclocking further due to this problem.
Thanks for any advice!
Thank you for your reply Robert. The system seems to stop after roughly 7 or 8 minutes of P95 testing. Around Temp 2 on Speedfan, it reaches 124C. The processor temperature stays fairly consistent at about 55C. If Temp 2 is accurate, it suggests a part is under significant heat stress. The gap between Temp 2 and the CPU is typically 15 to 20C, but it widens noticeably during the P95 test.
On the left side of the CPU there are numerous tiny parts, these are VRMs, you can touch them to check their temperature, if they are too hot a small heat sink should be placed nearby.
Hi
I finally experimented with my CPU and system fan settings, which helped the CPU fan operate more efficiently at lower temperatures and the case fans too. All fans were managed by temperature control. This worked well, keeping the temperature under 110°C at its peak, though it fluctuated between 100 and 110°C during the main test. It makes sense that this behavior is linked to the VRM's performance, as I've noticed in other sources suggesting a maximum of around 120+C. I think my motherboard was simply safeguarding itself by cutting power when necessary—a positive outcome!
During the P95 test, the main focus seemed to be on maintaining stable VRM temperatures rather than just CPU temperature. Since the CPU ran at a comfortable 55°C, the fan speed stayed low, which wasn't enough for optimal VRM cooling. Improving the CPU temperature to around 100% helped boost fan speed and reduce Temp 2.
Thanks again, Robert, for guiding me in the right direction!
I’ve now reached 4200MHz on the FX6300, but I anticipate it will become increasingly challenging from here. Still, it’s exciting!
