I have the 4600+ and I can't overclock it more than 300MHz. The 4200+ is 2.2GHz by default, and if you've increased the vCore and HT voltage, as well as underclocked your RAM, I doubt you would be able to overclock any more.
Some CPUs are able to overclocked more than others. Just live with the better speeds you already have
I have an X2 5000+ which at stock is 2.6GHz, but have it overclocked to 3GHz. I've booted and benched at 3.12GHz, but it wasn't 100% stable. Prime95 gave an error when I did the torture test.
What is your CPU multiplier, FSB, RAM timings and speed and voltage, CPU voltage at?
Also what cooling are you using for your CPU?
I have mine set to this:
FSB: 250 (200 default)
CPU Multiplier: 12 (13 default)
HT Multiplier : 4 (5 default)
RAM Timings: 5-5-5-15 (default 5-5-5-15)
RAM Voltage: 2.2V (Default 1.8V)
CPU Voltage: 1.462V "CPU-Z reports 1.5V" ( Default 1.35V)
This gives me:
CPU: 3000MHz (Default 2600MHz)
HT Speed: 1000MHz (Default 1000MHz)
RAM: 1000MHz (Default 800MHz)
I have recently got myself a Thermalright Ultima 90 which is like a mini TRUE (Thermalright Ultra Extreme) which is the best air cooled CPU cooler you can buy. My temps usually never exceed 60C whereas my old stock cooler at a lower voltage "1.45V" at 2.9GHz almost hit 80C when running Prime95.
Try and make sure you HT speed is 1000MHz or lower. Any higher can cause system instability. Use a program like
CPU-Z to keep an eye on your voltage and speeds. Use a program like
HWMonitor to keep an eye on temperatures. And use a program like
Prime95 to run a stability test. If you get errors than your PC is not 100% stable. Its a good idea to run the test while you go to sleep at night cause to know your PC is 100% stable you need to run it for a minimum of 6 hours. You can run it and still do other stuff though. I usually browse websites, listen to music etc etc while doing it, than leave it on while I go to bed, and look at the results in the morning.
