I honestly don't know if the same manufacturer produced bad caps for the BP6, but the BP6 definitely has caps made by Jackcon. My old BP6 board blew (*pop*) one such cap and the others have similar physical properties as the faulty ones reported in the VP6. Look for bulging cap tops and/or brownish ooze on top. You should pay particular attention to both (1000uF/10v) 2x2 cap blocks: EC{20,21,24,25} and EC{18,19,22,23}. I'll be fixing my BP6 board with new caps in the above locations as well as the reported EC10 cap problem. As far as I know, simply replacing the 1000uF/10v caps with non-Jackcon ones is sufficient. As per reports, I'll replace EC10 with a 1500uF/6.3v cap. I'll send out another note once my changes are complete (reporting success/failure). Regarding the VP6 cap problem, some people have replaced their own caps with caps of the same uF/v rating. Others, who have gone the RMA route with the VP6, had their caps replaced with altogether different ones, although I can't recall the uF/v rating on the new caps. -- -Dale To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
