K7D-L and pinmod....what the hell did I do?....ohoh

[VitoB]

I modded 2 x XP2800s to MP.....no problems when they posted last nite.
Tonight I decided to try the socket pinmod to unlock the multis.
So I did the 133x17 pin mod...checked everything twice then cleared CMOS and booted. I got one cpu showing as 2261 mhz..the other didnt post. No biggie I figured I'll just backtrack and fix it........ I was able to get into Windows XP fine .
So I shut down....checked the pin mods again with the diagram....rebooted and now I get nothing!...No screen, no beeeps, nothing. I cleared CMOS again......FSB to 100.....nothing.
I do hear a faint "clicking" sound and notice that the 4 LED lights are on and that the case fans dont seem to spin as fast as before.. So I tired booting with only 1 cpu...still nothing. I then tried a MP1600 cpu I had and nothing. Im using an Antec TPS550W.

Man O Man.....did I screw the poooch here?

Anyone have any expertise in troubleshoooting this?

you tried a known good chip outside of the pair you were messing with? try letting the board sit for the night after you clear the cmos, take the bettery out and unplug it from the wall and unplug the power connectors...then try again...while you're waiting on that test those 2 chips in another board to see if they are still good, if so, i'd say it's the board...if not ehn you're prolly out some cash...but from the sounds of it, the prognosis isn't good...

i had a few issues with my gigabyte board and my 2 xp1700+ @ mp2800+ ... no pin mods or anything but my blocks weren't seated correctly and were clogged and i toasted one chip...it took me 3 days to figure that one out...i had no post no beeps no nothing...you could push the power button and everything would power up but after that it wouldn't even respond to the power button...but now it's up and running as a single cpu machine till my replacement XP gets here...i've hit 2380mhz out of the 1700+...it was bridge modded for 2261@1.75v and i pin-modded for 1.85 but i think this board or PS has voltage issues...my next purchase will be a big name brand PS and maybe a venture into watercooling voltage regulators...they get damn toasty...

btw...how much was your power supply?

Have you removed the pinmods and tried again? Check very carefully for loose wires causing shorts.

I mucked up once and knocked a wire out of the socket causing a no post situation. put it back in properly and I was back in business (that was a volt mod on a single board, but the principle is the same).
