Zotac support finally broke their silence on this issue. Hopefully they'll come with a BIOS fix.

I tried a Highpoint RocketRAID 2300 controller on my Zotac's PCIe and worked. Unfortunately you have to forget resuming from S3 sleeping state when using any PCIe card. Initially Zotac said that is a known incompatibility with tv tuners but seems it affects most PCIe cards, including raid...
After hearing a handful of user reports, I tried using a plain graphics card on Zotac's PCI-E slot (radeon 5450).
Guess what! The same wake-from-S3 problem exists even when using a graphics card. That means it's not a TV-tuner incompatibility but a board/bios bug that affects PCI-E operation as...
Zotac first production batch of H55-ITX has a confirmed hardware defect (yep, another one) that prevents turbo boost from functioning, so unless you get an updated revision of the board you probably will forget this i7-750 feature. Unfortunately nobody knows what revision numbers these are and...
And the story goes on....
Seeing all these TV cards working on my friend's Zotac, I decided to order one too, same bunch, same retailer and close S/N. Well, it actually worked with my Hauppauge cards but the surprise came when I tried to wake up system from S3 sleeping mode. Guess what; It...
Here it is. Anybody can compare this with his H55ITX?
I confirm that this specific board, loaded with the latest bios, works fine with any of these tv tuners: Hauppauge HVR-2200, HVR-1700MC and BlackGold BGT3510. All these cards were detected by Windows 7 - (64bit) and worked with no issues...
Did Zotac release a new revision of their board? Two days ago, one of my colleagues got a H55ITX and he was able to use it with a Hauppauge HVR-2200 tuner. I've seen that combination working with my own eyes. :confused:
Board was ordered from Kustompcs in UK and came loaded with the latest BIOS...
Same time their forum mods have deleted most negative user posts, including their own comments regarding this and turbo boost issues; typical Zotac reaction... :rolleyes:
I'm pretty sure the answer is "No", Miguel. I don't see how they could fix this using firmware alone.
I guess they will release an updated revision of their board soon, same they did with their defective IONITX last year (yeah I RMAd two of them).
But I will not make the same mistake a third...
Just got what you meant, Miguel. :)
However, both EVGA's or Zotac's x16 slot problem is due to a bad design choice, not some chipset architecture limitation.
As I said before, Intel's own mini-ITX DH57JG board uses the same chipset but works like a charm with either GPU or non-GPU cards...
Sorry Miguel, but what limitation are you referring to? :confused:
I've built two H57 systems so far and none of them suffer from Zotac's issues. Speaking specifically about mini-ITX H5x boards, Intel DH57JG works just fine with PCI-E X1 TV tuners; i5 turbo boost works too.
Also, I didn't...
Turbo Boost doesn't seem to be the only problem of Zotac H55ITX.
Due some design fault the PCI-E slot only supports graphics cards and cannot be used with TV tuners or any other non-video hardware. :(
I canceled my pre-ordered Zotac and going to buy an Intel DH57JG instead.
