i know the Q8200 has a x7 multiplayer, and i have ddr2-800 ram so 800/2 = 400. So does this mean I can only overclock this to 2.8Ghz?

No, you can overclock farther.

The 1:1 ratio is just the overall most stable, it's not required. Some people have gotten best results at different ratios.

You could also overclock your RAM, if you have decent RAM and some cooling.

Your RAM should be able to OC past DDR2 800 speed, likely with a bump in voltage.

I have also a Q8200 OC to 2.8ghz, for some reason i cant set a 1:1 ratio on my mobo so I used 1:2 ratio and it's been working just fine since then (2 days ago), I also have DDR2 800mhz ram.

It has passed the stress tests and no crashes after playing for 5 hours. But I'm not sure what the benefit/loss is, if I set my ram like that.

Can someone explain it to me plz?

Is it a Gigabyte mobo? If so, 2.0 means 1:1.

It's a Foxconn Mars, I just double checked my numbers with cpu-z and aparently my FSB is 1600mhz and DRAM frequency is 400mhz, FSB:DRAM 1:1

So I think theAnimal comment makes perfect sense @_@; latencies 6 6 6 18
I also lowered the cpu voltage, because it was too high for a 45nm cpu (1.275v).

So now you can say it's posible to OC a q8200 from 2.33 to 2.80 with ram at 800mhz and stock voltage. The change in temp was like 5-8 degrees, before i had 37 idle 46load, after the oc I have 43 idle 53 load with a Tuniq tower 120. These changes in temps might be wrong though, room temps change a lot in this country.

Depending on what brand your RAM is, you may or may not get significantly beyond 800 with it, also you can up the voltage and play with the timings to squeeze it a little. Going to 1066 RAM should help a lot. Also it depends on your mobo, some of them have difficulty going beyond 450MHz, but 450x7=3.15GHz.
