I have experience OCing with the Socket A's and which Multiply x the FSB and it gives you the overall clocked (and PCI Bus is locked) and then you just adjust voltages accordingly.
I built and OCed a AM3 system for my sister and it was the same formula.. except there was a North Bridge Frequency right? Which for her motherboard was around 2000Mhz, so after overclocking, I had to throw on a divider to get somewhere in-between stock NB clock frequency.
SOOOOOO now fast forward 2 more years, and I just recently built myself a FM1 socket system. So it looks like its roughly the same... but.. whenever I move the clock speeds just a BIT, it seems to fail windows load.. However when i OC using the manufacture software (not bios) it seems to work.. but ends up being unstable and crashing (with software overclocking i can change from the stock 3.0Ghz to up to 3.7Ghz)
However when i use the bios to overclock.. it seems so unstable i can't even get windows 7 to load up.
Here pictures of my bios screen.. not sure if there are other options to use to overclocking, I have the most up-to-date drivers from ASRock (it came like that stock.. i never flashed the bios before)
now heres the tab i changed from auto to manual to set cpu voltages and multiplyer.. also it has the NB frequency and volts.. from my assumption.. i thought I all had to worry about was CPU multiplyer and voltages... the rest I could leave stock.. am I wrong here? the NB Frequencies tab allows me to change it from 228Mhz-900Mhz.. I have no clue what the stock settings are because I don't see it in the CPU-Z like I did with the AM3 system I built... but when I drop the tab down it is defaulted at 720Mhz.. so Iam guessing its stock at 720?
my real concerned is about the NB frequency.. because i don't see it ANYWHERE on the CPU-Z like I did when i OCed the AM3.... are these NB frequencies locked now or something? or do I still need to worry about setting this when I overclock?? Because I don't see it anywhere in the CPU-Z to even know if it has gone up when I change the frequencies.. heres my CPU-Z:
Anyways.. i consider my attempts at overclocking so far a disaster! I would be happy if I could just OC it a little bit from stock.. 3.0Ghz.. I would be happy if I could hit 3.2Ghz+ I was really hoping to see 3.5Ghz or 3.9Ghz reading from reviews and other members and reviews from retailing online stores.. but it looks like I can't even get past 3.1Ghz...
