AMD Athlon II X4 620 OC Questions

Hello!

First of all, I want to say "HI" to the community! I'm new here and also I'm a rookie in OC. I hope to find some answers and to get some good advices from you.

My PC is equipped with:
MB: ASRock A780 FullHD (video onboard)
CPU: AMD Athlon II X4 620
RAM: Samsung M3 78T5663QZ3-CF7 2GB DDR2 800

I'm trying to overclock my PC and here is what I've done so far:
FSB: 240
Multiplier is blocked at 13x
DRAM: 6-6-6-18
HT: 1920MHz
NB: 2400MHz

No voltage adjustments are made.

So far, my CPU is at 3120.1 MHz (I'm satisfied) and RAM at 800MHz. But the FSBRAM ratio is at 3:5.

What I have to adjust to bring the ration to 1:1? And how can I keep the overclocking safe?!

Thank you in advice!


PS. Sorry for my bad english.

Not sure exactly what you are asking and if you can post a pic of your bios settings that would be helpful!
