AMD Phenom II 810 x4- Overclocking

post #1 of 8
Thread Starter 
I'm trying to over clock my Phenom II 810 and would appreciate some overclocking help

Right now im up to 3.4ghz and wondering if i could go much higher

One of my real concerns is in CPU-Z it displays my VCORE as 1.525 when in BIOS it is at 1.45

Is this normal or even safe?
I have read before to trust BIOS over software but I as still concerned.


Another question I have is that to achieve a stable overclock I need to lower my DRAM frequency a notch

I am wondering how this will affect performance
I the higher overclock worth it if the DRAM must be lowered?

Thanks and I would appreciate any input

Your vcore is a little too high. I recommend that you shouldn't go over 1,45v. It's normal that the effective vcore is different from the one you set from bios. Every motherboard try to keep better stability by increasing the voltage. Make sure you have disabled cool'n'quiet and c1e.

Could you make a screenshot of cpu-z?

1.525v's fine/safe on those chips. I've got loads of Knowledge of overclocking them, I've got a gold and two silvers on HWBot. What does the reading of the CPU voltage say in the bios?

Normally when Ram holds back an overclock its to do with the amount of sticks, not the speed. So your Ram should be not holding you back at all.

The most I got out of those chip was 3.6GHz super stable and 4.2GHz on phase.

Thanks for the replies.

I feel a little safer now.

This helped me to achieve a higher DRAM frequency ( prolly should have figured that one out on my own haha)

But its not stable under stock voltage
Any recommendations for a safe CPU/NB voltage?

I didn't know the 810 was a C2 stepping. This means you CPU is a little more difficult to overclock and you have to set higher voltages to vcore.
Increasing the host clock frequency, also your ram frequency will grow. To test you cpu stability, you can set you memory multiplier to 1 step below the default value (if you have 1333 DDR3, set multiplier not to 6.66X but to 5.33).

277 always used to be the FSB for me. You should try setting that, CPU will be clocked at 3.6GHz and CPU-NB will run at 2770, set memory to what ever is stable. Voltage wise I would set 1.475v to 1.525v on both the CPU and CPU-NB.
