Overclocking Fx 8320 + M5A97 R2.0 to 4.4 Ghz
Overclocking Fx 8320 + M5A97 R2.0 to 4.4 Ghz
Hi guys,
I'm attempting to overclock my FX-8320 (hyper evo 212) on an Asus M5A97 EVO R2.0.
I've followed the guide provided and achieved around 4.4 Ghz with the following settings:
-CPU Ratio: 22
-CPU NB Frequency: 2200
-HT Link Speed: 2400 (2600 not available)
-CPU Manual Voltage: 1,26
-CPU/NB Manual Voltage: 1,25
After about 20 minutes of P95 Small FFT, I obtained the following readings:

which appeared to be a very positive result.
Following that, I tried increasing it slightly to 4.6 Ghz, but stability was lost unless I raised the CPU voltage to at least 1.32, which then caused the socket temperature to exceed 70º.
In summary, my question is: Does this significant jump in ratio make sense? I've heard about large voltage increases in certain CPUs, but wasn't expecting such a high ratio. My motherboard or cooler might be subpar and possibly the cause, though I'm still unsure.
Thank you for any advice you can offer.
Ensure your motherboard VRM is functioning properly. Monitor temperatures; if any exceed normal ranges, consider reducing overclocking. The Asus M5A97 EVO R2.0 may struggle with 8 cores, often throttling or overheating. Standard VRMs aren't ideal for AMD 8-core CPUs, though some reports suggest they can handle it at stock voltage, which might be too high. Keep motherboard temps below 70°C and adjust voltage accordingly—CPU-NB should support around 1.17V for 2200MHz, helping lower CPU and board temperatures slightly.

Ensure your motherboard VRM is functioning properly. Monitor temperatures; if any exceed normal ranges, consider reducing overclocking. The Asus M5A97 EVO R2.0 may struggle with 8 cores and can throttle or overheat if not managed. Naked VRMs aren't ideal for AMD 8-core CPUs, though some reports suggest they run too hot. Keep motherboard temps under 70°C—lower voltage if necessary, which might require adjusting your overclock settings. Your advice on reducing CPU-NB voltage was very helpful. Currently I achieve around 4.5 Ghz with stable voltages and temperatures staying below 70°C. Occasionally the MB throttles CPU to 1.4 even when temps drop below 70°C.
