Re: PCI capture cards on Intel Sandy Bridge
[In reply to]
To clarify, I'm talking about the on-board PCI slots on the motherboard,
not an add-on PCI-over-something adapter.
For example, the below board, which is one I was looking at, is a
sandybridge H67 chipset board, with 3 onboard PCI slots.
The 'consumer' sandy-bridge chipsets H61/H67/P67/Z68 do not have PCI
'built in', only PCIe, so those 3 PCI slots on this board are driven by
an ITE8892E PCIe-to-PCI bridge chip, which is fed from one of the PCIEx1
lanes out of the H67 PCH.
Same story with any board with the aforementioned sandy-bridge chipsets,
with Gigabyte also seeming to use the ITE8892E, Asus using the ASM1083,
and other mobo vendors seeming to use one of these two bridge chips.
I haven't found any one good summary of this issue online to point to,
but a search for 'sandy bridge pci' , over half the first page results
are about this issue. It seems like it is more noticed by users of high
end audio cards, and some specialized interface cards. It basically
seems like the PCI slots driven by these bridge chips are not up to the
same 'performance / standard' as earlier chipsets.
So, the intent of my original question is to figure if this is an issue,
or a non-issue for PCI capture cards, on these motherboards. The fact
that I have found few references online of capture card woes with
sandy-bridge seems positive, but I was just wanting to make sure.
Forewarned is forearmed, etc, etc.
So, is anybody is happily (or unhappily) using PCI capture cards on a
Intel H61/H67/P67/Z68 based (sandy-bridge) motherboard?
