I have an Abit VT6X4 (YK BIOS) with a P3 1ghz (133 mhz) and 256mb of PC133 ram (not over clocked). Ram is 2x 128mb.
I was getting an error similar to: cannot load Win2K. systemced not found. I traced that back to a known problem with my Promise ATA66 board & Win2K Pro.
I moved my drives around so that windows does not boot from the Promise card. I think I got that cured.
When I did that, I had to remove the processor and both sticks of ram (to get the drives out safely). All seemed to go fine. I built the system, so nothing seemed to be out of the ordinary. No static, no snaps or pops. I was careful, grounded & sober.
When I rebooted, the bios said the processor had failed or been changed and hit F1 to continue or DEL to enter set up.
The bios is seeing the 1ghz P3 as a 500e P3.
I'm also getting the big single beep. I've narrowed that down to 1 of the dimms being screwed. It was running fine at 133mhz just an hour before I did this.
Now, I've fiddled...and got the processor to run @ 750mhz (100mhz bus). It will not run @ 133mhz.
The lone stick of ram will not go over 66mhz even though its PC133. The other stick will not work at all in any of the 3 dimm slots, therefore that stick has to be dead.
I doubt I cracked the board, because its running.
Currently it's set up at 100mhz x 7.5 DIMM is HCLK-PCICLK 100mhz-33mhz=66mhz.
The bios will not let me go past the 100mhz x 7.5 barrier. 133mhz gets the big single beep again.
I've done the CMOS jumper too.
Reset safe defaults etc. No luck.
Any ideas or suggestions are appreciated.
