I think you need to get answer for below questions first.
1. Is the PCIe X16 slot is working fine? ( You can use any other card to double check the functionality of PCIeX16 slot of the board)
2. Whether this PCIe X1 card is compatible to PCI e X16 slot of the board? (Technically PCIe X1 card should work on PCIe X16 slot, you can check with card vendor to get confirmation on the same)
Thanks for participation, Tommy.
1. Yes, slot works correctly. A video card (PCIe x16) and I/O Controller Card (PCIe x1) remarkably work.
2. TBS 6921 perfectly works on others motherboard, both in PCIe x16 slots, and in PCIe x1 slots...
I beleive this is and "old" Problem plugging the mini-ITX boards. I have a DH57JG (Socket 1156) with the same problem. I strongly believe it is related not only with the board but with the Power supply of the case. I have my board within a in-Win BP655 case with a 200Watt TFX power sypply. I think the specific power supply has only 10A in the 12V+ rail which is not "enough" to drive the processor and motherboard correctly. I dont have any BSOD or other problems exept the PCi-e x1 problem. I haven't so far figured out what is exactly the culpit but i am close.
P.S: The Zotac mini-ITX H55 boards had this problem in the begining but it was solved with a BIOS update. Maybe this the case with the rest of us on Intel mini-ITX boards.
Thanks for the substantial answer. It is rather probable that the reason in BIOS. I changed the Power unit on POWER MAN 350W, without result.
I have a DH67CF and I ma using a PCI-E x1 wireless card with it absolutely fine. I was surprised at how easy it was to set up to be honest!
I too have been unpleasantly surprised by such situation... The сard SHOULD work, I/O Controller Card (PCIe x1) confirms this rule. But... TBS6921 it do not agree with it.
I have a similar problem. A Blackgold 3540 that works in another machine, isn't detected on the DH67CF (Doesn't show in the BIOS or Windows). I have tried another card (a USB controller) in the DH67CF and it works fine.
Sincerely I sympathize. My problem isn't solved till now. Updating BIOS on version 01.10 hasn't helped. It is necessary to wait for a miracle...
Same problem, but with ASRock H67M-ITX board and AverMedia Duet A188 PCI-E x1 TV Tuner card. It's so disappointing when you read all over the web that PCI-E x16 slots will autonegotiate and accept PCI-E x1 cards but then find out the hard way after you have bought all the components and tried to put them together.
My question is is this a limitation of the motherboards or Intel's chipset. Should I bother looking for a different H67 motherboard?
Yes, I agree! It is very unpleasant, when you receive a problem suddenly. All assert that devices should work, and actually they don't work...
I can tell that my problem has left after installation of last version BIOS (0119).
Hence, the reason in concrete motherboards!
After updating BIOS to version 0119 the problem has left.
I have the same problem with the Asrock board rushidesai, and I've read there are many other brands affected.
I agree, very frustrating.
Its good to see DimaM see the problem fixed, lets hope there are similar BIOS upgrades from all the other manufacturers soon.
