Greetings,I overclocked my FX 4300 stable to 4.6ghz@1.38v
Both CPU and VRMs stay cool(cooler on cpu is Katana 3 while VRMs have active cooling),but when I try to push it past 4.6ghz,lets say 4.7,it won't post.I also tried to increase voltage even further but same results happen.If I try to overclock with AMD Overdrive,it can go up to 5.5ghz but when I check CPUz,actualy frequency get's lowered to 3.2ghz.Any tip for aditional overclocking?

What motherboard and RAM are you using? Waht are your voltages and speeds? Need more info.

For FX CPU, usually a mix of CPU vCore and CPU NB voltage is needed for stability. This usually works for Multiplier OC.

If you are doing FSB overclocking, you usually need to step your RAM down 1 speed notch so it stays stable. You also need to increase FSB and HT voltage a bit.

Here's a good guide and reference for you:

You should be really happy to have any OC at all :)

That's not much of an OC motherboard -- it's likely 'throttling' to keep from catching fire (a semi-serious joke). It's possible you may be able to eliminate the throttling by disabling 'APM' (the core-throttling feature) in the BIOS.

Some budget motherboards will 'APM' to protect themselves even if you disable it ...

Told you already i put active VRM cooling on the mobo :D .They don't even get hot at full CPU load,never got thermal thermal thortle because of VRM or cpu temp.
