I'm using a 212 Hyper EVO cooler with Arctic Silver thermal paste and a GA-78LMT-S2P motherboard. Despite the 8350 reaching 4 Ghz, Core Temp shows a max of 40C and speeds underclock when running Prime95. How can I push past this? I've adjusted voltage on vcore and cpu/nb, tried boosting CPU/NB to 2400Mhz and HT Link to 2400Mhz, but both reset to CMOS. What else can I try?

Here’s the revised version:

I’m using a 212 Hyper EVO cooler with Arctic Silver thermal paste, and I’m running a GA-78LMT-S2P motherboard. Despite that, I can achieve 4 Ghz on the 8350, but when using Prime95 the core speeds are underclocked even though Core Temp shows a maximum of 40C. What can I do to get past this? I’ve adjusted the voltage on both vcore and cpu/nb, tried boosting CPU/NB to 2400Mhz and HT Link to 2400Mhz, but both ended up resetting the CMOS. What else can I try?

That was really useful, and it was the top guide I came across.

Check that page provided was useful and helpful. It seems to be the best resource I've found so far. My 8350 is running at 4.68, and I'm unsure how to adjust voltages since the guide doesn't address this issue directly. The temperatures look normal, so I'm not sure if boosting voltages will resolve the underclocking.

I'm trying to clarify my setup: I'm using a 212 Hyper EVO cooler, Arctic Silver thermal paste, and a GA-78LMT-S2P motherboard. Despite the Core Temp showing only 40°C max, the core speeds are still being throttled when running Prime95. I've adjusted the voltage on both vcore and cpu/nb, and increased CPU/NB and HT Link speeds to 2400Mhz, but both ended up resetting the CMOS. What further steps can I take? My motherboard doesn't support FX 8 core processors, and it only has 4+1 power phases and 8 core processors, which aren't sufficient for proper overclocking. I think I need at least a 970 motherboard, preferably a gaming model with 6+2 or 8+2 power phases and VRM cooling.

I'm trying to clarify a few points about my setup: I'm using a 212 Hyper EVO cooler, Arctic Silver thermal paste, and a GA-78LMT-S2P motherboard. I can get the 8350 to run at around 4 GHz, but Core Temp shows a maximum of 40°C. Despite that, when I run Prime95, the core speeds are being underclocked. I've adjusted the voltage on both vcore and cpu/nb, and increased CPU/NB and HT Link speeds to 2400Mhz, but both ended up resetting the CMOS. My motherboard doesn't support FX 8 core processors. It only has 4+1 power phases and 8 core processors, which should require 8+2 power phases and proper VRM cooling (heat sinks) to overclock effectively. I think I need at least a 970 motherboard for this chipset, preferably a gaming model with 6+2 or 8+2 power phases and VRM heat sinks. I was surprised to be able to push this board so far, likely due to the good airflow in the case. I'm considering investing in a better motherboard with an Intel socket for better performance and quality, especially since my AMD experience hasn't been as good. The FX-8350 I bought separately was clocked at 2.8 GHz, probably because the board detected it. Thanks for your advice.

Dylan531 shared his experience with the 212 Hyper EVO cooler, Arctic Silver thermal paste, and a GA-78LMT-S2P motherboard. He managed to achieve 4 GHz speeds on the 8350 but noticed underclocking in Prime95 despite a Core Temp max of 40°C. He sought advice on further improvements, mentioning attempts to adjust voltage and clock speeds, but encountered a CMOS reset. He explained that his motherboard lacks support for FX 8 core processors and recommends a higher-end board with better power phases and VRM cooling. He also shared that the FX-8350 was clocked at 2.8 GHz by default due to motherboard detection and suggested considering an Intel socket board for better performance and quality.
