Subject: Re: C3600, sata controller
Date: Sun, 12 May 2019 17:10:05 -0400	[thread overview]
Message-ID: <f52cf203-c48a-fd04-5827-19903c3a192f@bell.net> (raw)
In-Reply-To: <CA+QBN9A4PhPZ36otsk0TRaO9KKnKL=hfnskfFJGQJEbtb3=i=Q@mail.gmail.com>

The c3600 doesn't have any PCI-X slots (only PCI) as far as I can tell from user manuals.

The SY-PCX40009 PCI-X card that I have says it supports two models: 32-bit at 66 MHz and 64-bit
at 133 MHz.  The 32-bit slots in c3600 are 33 MHz.  Whether the card will work at 33 MHz is not
clear.  The card says it's backward compatible to PCI 2.3.
