i followed some advice from someone that kindly helped me out :)  i have an intel 975bx2 and the memory i have is just mushkin 1.9v ddr2 800 5 5 5 12 memory. When i down leveled my memory to 533 upped my memory voltage from 1.85v to 1.92 because the memory is 1.9v and upped my host clock override under processor to 333. Does this mean i have to set my "reference frequency "n memory to default or 333 also? (havent done that yet) i got 2.9 ghz!!! BUT!!! now it says my system has a OVER RIDDEN system bus frequency of 1332 via bios. is this normal? wont this melt my board , this is just an intel 975bx2 not a 680i. by the way, whats the point in DECREASING my memory for and OVER clock ? do i get any kind of performance gains from keeping it at ddr2800?

when overclocking, manually set everything so you know for sure what everythings running at.

Intel mobo's are not all that great for overclocking.

Performance diffrence between 533 and 800 isnt much, its better to have the ram run in sync with the cpu fsb (when overclocking anyhow, easier)

No, FSB1333 is just 333MHz using Intel's Quad Data Rate bus. By selecting the "533MHz" memory setting you actually chose a 1:1 ratio of memory clock to FSB clock, 333:333, DDR2-667 to FSB1333.

Like I said, this isn't much of an overclock for the chipset, nothing to worry about.

i don't think that it really even qualifies as an overclock for the chipset as afaik the BX2 supports 1333 CPUs

As a general rule: voltage should be 2.1v - its good for all low end memory with a heat spreader.

raise the mch voltage up

run sandra bandwidth test on different memory settings

adjust latecnys after you get it close
