I did two sets of cap replacements: the first : was replacing the 1000uF/10v caps in EC{18..25} with identically rated, : non-Jackcon caps; the second was replacing the single 100uF/10v cap in : EC10 with a 1500uF/6.3v one.

The second I did as recommended in several places, one of which : quotes Abit UK thusly: "...all that is required is to replace the EC10 : capacitor with one, value 1500uF/6.3v." So, yes, EC10 is replaced with : a 6.3v, but it's the recommended fix and the original cap is the wrong : one anyway. :-- :-Dale Yes, but what is the voltage measured across the cap when the machine is on? Measure both the AC and DC voltage if you can. If you have a multi-meter, that is. If not then, oh well. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
