hiya. total noob here. attempted to oc a 2.4c but things went awry. my machine doesn't boot anymore. black screen. sheer silence. all i see is a lone mobo LED. no PSu fan whirring. nothing. specs --> abit 1c7, 2.4c, X800 GTO, mushkin basic (2.5), fortron 350. original ---> Ext. Clock (CPU/AGP/PCI) 200/66/33 after a little blind tinkering ----> 220/62/31mhz i left the DRAM ratio (CPU:Ram) By SPD (1:1). my options here - which i did not tamper with - were 3:2, 5:4, 1:1, and By SPD. initially, i wanted to keep things 1:1, figuring this was the easiest and safest route to begin with. but the jumps may have too much too fast. i went from 210 (which was a success !) to 220. failed, wretchedly. i tried jumpering the CMOS. nothing. any ideas, please ?!?
