Overclocking Fx 8320 + M5A97 R2.0 4.4 Ghz

[Busilis]

Hi guys,

I am trying to overclock my FX-8320 (hyper evo 212) on an Asus M5A97 EVO R2.0.

I've followed this guide and reached 4.4 Ghz fairly easily with the following configuration:
-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've got the following readings:

which seemed to be a very good reading.

After that, I've tried to bump it up a little to 4.6 Ghz, but I couldn't get it stable without setting the CPU voltage to at least 1.32 at which time the socket temperature could not be kept under 70º.

So, summing it up, my question for you guys is: Does this big step make any sense? I've heard there big wall in kind of CPUs but was not expecting it to be at this ratio. I understand my MB or cooler are hardly top shelf and could be responsible, but still... Or am I missing something obvious?

I appreciate any advice you can give me.

Thanks in advance,

You need to make sure your motherboard VRM's are in check, Check the temps and if anyone of them are too high, you need to back down you'r overclock.

The Asus M5A97 EVO R2.0 are not vary good with 8 cores and I see reports of them throttling and often eventually burning up if not kept in check. Naked VRM's are not good for the AMD 8 core CPU's, Stock they are normally fine with some reports of being too hot. If the motherboard is above 70C, lower voltage some, which you may have to lower your overclock.

If you have to lower voltage, CPU-NB should be able to do 1.17v which is its stock voltage for 2200mhz which should lower the temps of the CPU and motherboard a little bit.

Tks.
Your tip on lowering the CPU-NB voltage helped a lot.
For now I managed to get 4.5 Ghz with little over 1.3V on the CPU Voltage and the CPU-NB to auto.
Temps are keeping below 70º.

Indeed I saw the MB throttling the CPU to 1.4 in some occasions even below 70º.
