I'm stressing my CPU prime95 and of course i'm monitoring temps with hw monitor. Temp are ok below 70 celsius. I will increase the fsb from 333 to 389 with multiplier 9. With that multiplier the DRAM frequency will be something below 800mhz. Do i need to increase north/south bridge voltage or DRAM voltage. What is Vtt voltage and do i need to increase that?
