Atomix, don't bother. i know you can.
You should validate that 4GHz using CPUZ. make sure you put your OCN Avatar name down, an email address and hit submit.
now, these are my cpuzs . . .
as you become familiar with your bios (like you are it seems) - you are right playing with the multiplier (x18) and the FSB (212). raising the FSB will overclock your RAM frequency and the HT Link (as you already observed). You need to adjust these two either back down or higher. For the HT Link, most recommend to set it at 2000MHz. The RAM, on the otherhand, just make sure to set it as close to manufacturer's for now. Again, others set the RAM oc first, run stability test for a few hours, then set the CPU oc. Your choice. If your RAMs are *cough* cheap - i suggest setting it at manufacturer's spec.
i knew are chips behave similarly except that our board, our cooling solutions are different and other stuff are different. At 4GHz oc our temps would be lower than 40C depending on the ambient. mine stays at 36C during games. Almost as cold as the HDD. lol:thumb:
BTW, see that NB Freq on the second CPUZ window? that you can raise as far as you want as long as it is stable. not really . . .prolly 3000MHZ with a CPU/NB vcore of 1.375v (-/+). Now some of these labels will be different in your bios but their values will be the same as the CPUZ.Edited by rdr09 - 8/31/12 at 9:34am
