oh yeah btw room temp is 27 C
what if I can get further at stock voltage ?
what does overclocking without additional voltage increases means ?
I tried 470 Mhz but failed, then I bumped up DRAM voltage from 1.80 to 1.85 in BIOS. and now it's running and testing it, I think it will be fine at 470 now:

470 Mhz @ stock NB voltage....wtf ?! are you sure that it really needs the voltage at 430 and higher ? looks like only at 470 and higher
and yhe don't be confused by the "CPU Fan" speed because this is the RAM fan being connected to the CPU FAN slot, the cpu is of corse cooled with water
I have reached 480 FSB with stock NB voltage !, tried 490 but the system does not post anymore
hmmm, I think I have a problem !, it seems that no matter what is being done the system will refuse to boot at 490 FSB

((((
I tried to increase voltages everywhere, sometimes a little more than should be necessary but it has no effect, the system will not reboot from BIOS after the change has been made...
however, if the system is being shut down, then the PSU power switch has been shut down, and then try to boot it with PSU power switch being off several times, then power the PSU, then power up the system and the system will boot at 490 Mhz ! strange ! but if it still works then why not, unfortunately when the system powers up after that it defaults to stock FSB, which is not good, so this does not work
I think the maximum reachable FSB with the mobo is only 480, maybe a little bit higher, managed to reach 489 Mhz with stock NB voltage
