Title: Differences in A3000 Motherboards
Post by: Sandman on February 24, 2010, 04:42:39 PM

I just got a hold of a couple of rev. 9 A3000 motherboards.  I already have a sweet system built with a rev. 7.3 and am wondering if it would be worth tearing down my whole system to upgrade the motherboard with the newer rev.

Any ideas?

I second that emotion  :)  Only monkey with mobo replacing if only absolutely necessary or you're extremely bored and are willing to take the chance of accidentally mucking something up.  lol

Perhaps some new rev. of chipset: look Western digital SCSI and other chips.

Do you have the rev.7.3 A3000@16 ou 25Mhz ?
Nothing really new between 7.3 and last Motherboard otherwise ROM modifications.

Good to know! I was tempted to do the same operation with mine since it has an older rev. motherboard although it has the latest chips (WDC 08, Ramsey 7, Superdmac 04 & Superbuster 11). Better not touch itm according to that info, it's just not worth it :-)
