Zotac H55ITX-A-E query

Hello guys,

Am I right in thinking that the PCI-E 16x slot in this motherboard can support up to an 8x expansion card (not a discrete GPU) without losing the onboard GPU?

Thanks.

H55 cant split the lanes so the onboard gfx is using all 16 lanes on the chip.
The southbridge however has 6 extra x1 lanes available.

This diagram explains it better

ah, ok thanks.

I just came across this while following up the information you had given.

Dear Sir,

We are sorry to tell you that the PCI-E x16 slot is provided for display card only. For other add-on cards, the card may be not functional. You could try to update the TV card driver or use Hibernation mode instead of S3 mode.

That's a bit lame for an ITX.

Can anyone tell me can you use a 4x PCI-E card in the Sapphire IPC-AM3DD785G without it disabling the onboard GPU?

I'm basically looking for an ITX board with electronically 4x PCI-E slot (4 lanes), it seems to be mission impossible.
