fx 4300 overclocking issue

Hello.

I am currently running a fx4300 on an asus m5a97 r2.0 with a cx 500.
I have been trying to overclock my cpu up from the stock 3.8Ghz. I have been in the bios and disabled the turbo function. I have no problem going up to 4.5Ghz without changing the voltage. This raises my cpu´s performance by 15-20%
If I go to 4.6Ghz the cpu gets warnings in prime95 and core 2, 3 and 4 shut down, leaving only one core operational. So of course I upped the voltage, I upped the voltage to 1.3V on the core and managed to get 4.8Ghz to run in prime95 with my cpu staying under 60 degrees Celsius (140 Fahrenheit) But the performance drops back down to what the cpu performs at stock. Can anyone help me? Thanks :)
All the overclocking is done in AMD Overdrive*

Overclock via the bios only.

 

If the cpu scores the same at higher speeds means the CPU is starving for voltage or throttling. It should need alot more voltage then 1.3V to run anywhere near that speed.

My motherboard does not allow me to adjust my multiplier, so that is why I did it in my os. I was running at 1.35V on the core and staying under 60C. This is why I am confused, i do not see the problem, so what have I missed?

Yes it does. Go into Advanced Mode and change the multiplier and voltage. 1.35V for 4.8 is still quite low IMO.

Trust me I have tried but I can only find the BCLK Frequency, but if you are right I must have missed it, an I shall have a third look :) As a test I ran 4.6Ghz at 1.35V and got the same result, the cpu performed the same as stock.
