i do thank you for your help, but as far as i'm concerned, my problem is solved. i understand that too much voltage is not good, but the increase is necessary for the proc to run stable (if i burn it up, then it will be that much quicker that i'll be getting a phenom II). but, just because someone else calls it a front side bus, doesn't mean that's what it is. on an amd proc, there is no front side bus. you have, obviously, the proc's stated speed. then the hyper transport link and the reference clock. the hyper transport link runs at 1ghz (on am2 boards, which mine is). the hyper transport link is a 5 times the reference clock of 200 mhz, thus, 1ghz. the default multiplier on my board is 14x. so 14 times 200mhz (the reference clock) is 2800, or 2.8ghz, the stock speed of the athlon 64x2. to do an overclock, i would increase the reference clock say to 210mhz. so then, my chip would be running at 2940mhz, or 2.9ghz. but since the reference clock increased, the hyper transport link speed increases too, since 5 times 210 is now 1050. if i increase the reference clock too high, the hyper transport link will get unstable and as far as my system goes (cause i've done it), it will crash the system. as i've stated, i have an unlocked multiplier, so my overclock was performed without messing with the reference clock. but since the cpu is running faster internal clock, without the extra voltage, it will not run stable. the photo included is taken from the january 2008 issue of maximum pc, where they performed some overclocks on 4 different amd procs. note the voltages involved. the default on my board is 1.3 volts (as what i'm sure is the default of the procs listed in the picture)
the second pic is further down the page of the same post you gave me the link of. and, the main thing about the increased voltage is increased heat. so even with the overclock and voltage increase, i have consistent 28c temp idle and 48c during load.
