Re: K7SEM capacitor identification
do you still have that 6800?
a shitload of these got thrown out because one (!) mosfet shorted out (so you'd end up with a full short on the 12V side of the additional molex connector.. urgs)
fixed quite a bunch of these..
oh and... that description of the additional LAN port of the K7SEM (it's called AD-LAN btw) sounded kinda familiar... so i went digging..
guess what?

board was thrown out because no matter what RAM you put in it, it always puked out errors in memtest86. got it for free with a 1.8GHz Duron Applebred (1.5V Vcore )
OSTs on VRM out were bulging, all others looked fine.
mostly recapped, and it's rock solid again. to really get this b*tch running stable, you have to replace ALL the tiny 16V 100uF craps. this thing is riddled with tiny dry-up-G-Luxon's
i used LTec TK because i had a whole bag (500pcs) of these that i bought for next to nothing. their datasheet is kinda ... interesting..
so... these things withstand high reliability..!? wut..
oh and removing the northbridge heatsink, getting the double sided tape crap off and putting it back with thermal glue also helps A LOT..
that tape stuff seems to be more of an insulator than anything else..
this is one of the rare occasions where i reused old good brand caps from dead (asus socket A) boards. didn't wanna waste money on this thing. turned out to work just fine..
edit: as for the GF6800.. the mosfet labeled Q509 failed shorted

got a few of them (old pic)

(note that the 6800GT (the one with the blue cooler on it) has the exact same PCB layout as the 6800 Ultra just missing some parts)
and here's my thread about the fried mosfet (posted 2 years ago.. god how time flies)

Designed for consumer products, which require to withstand high temperature and high reliability.
