GA-MA780G-UD3H PCI Express slots
« on: October 06, 2011, 03:02:07 pm »
Hi , I have a question about the PCIEX slots on my motherboard .

According to the webpage and manual for the GA-MA780G-UD3H :
"The PCIEX1_2 and PCIEX1_3 slots share bandwidth with the PCIEX4_1 slot.
When the PCIEX4_1 slot is populated with a x4 card, the PCIEX1_2 and PCIEX1_3 slots become unavailable."


The manual does not make clear what happens if the PCIEX4_1 slot is populated with a x1 card .

Can anybody tell me if PCIEX1_2 and PCIEX1_3 slots become unavailable if the PCIEX4_1 slot is populated with a x1 card ?

I started a support ticket asking Gigabyte a few days ago , but have not had a response yet ,

Thanks

Hi there,

reading this:

(Note 4) The PCIEX1_2 and PCIEX1_3 slots share bandwidth with the PCIEX4_1 slot. When the PCIEX4_1 slot is populated with a x4 card, the PCIEX1_2 and PCIEX1_3 slots become unavailable.
from the Gigabyte spec's for your motherboard I would think that using a PCIex1 card wouldn't be a problem. The issue arises only because an X4 card would want all the bandwidth whereas using three X1 cards wouldn't.
Remember, when all else fails a cup of tea and a good swear will often help! It won't solve the problem but it will make you feel better.

Hi ,
Thanks for the reply ,

So , because Gigabyte make no specific mention of x1 cards using all the available bandwidth it's safe to asume that it's ok ?

I'll be ordering a PCIex1 dual DVB-S2 in the next few days , and wanted to make sure it'll work .

Thanks .

Hi again,

that's my understanding of the situation. If you like I can ask Gigabyte for confirmation of this but it might take a few days for them to get back to me and you will probably have an answer from Tech Support by then.  :-\

If there is a PCIE X1 card in PCIEX4_1 , the PCIex1_2 and PCIex1_3 are still available .
