Gigabyte's Sandy Bridge Launch MBs

P67 UD7

1. 2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots.



2. 2 x PCI Express x16 slots, running at x8 (PCIEX8_1, PCIEX8_2)
* The PCIEX8_1 slot shares bandwidth with the PCIEX16_1 slot and the PCIEX8_2 slot with PCIEX16_2. The PCIEX16_1/PCIEX16_2 slot will operate at up to x8 mode when the PCIEX8_1/PCIEX8_2 is populated.
3. 1 x PCI Express x1 slot
(All PCI Express slots conform to PCI Express 2.0 standard.)
4. 2 x PCI slots



took me second to grasp that :> so if i have just one 580 in the 16x1 slot according to them if i install a revodrive in the other 8x2 slot i should have them both running at 16x and 8x without any slow downs or halving of lanes and still have space left for a soundcard in the pci-e 1x slot nice!.

how much will you have to pay for this premium though? ><

Really? Not how I'm reading it. Seems to say if a x8 slot is populated then the x16 will only run at x8. Where does it draw a distinction between using a GPU or another PCIe card in the slots? I must be missing something if that's what it says?:confused:
 
Won't matter if it's a GPU or another card, plug it into one of x8 slots it'll steal 8 PCI-E lanes from the corresponding x16slot, even if it's only say a x1 soundcard.
 
what? i thought it meant they are seperate(4x 16x lanes) it says the 16x1 and the 8x1 are linked and the 16x2 and the 8x2 are also linked.


what i mean is, keep the GFX in 16x1 and dont use the 8x1 but instead use the 8x2 which is linked to the 16x2, its not two seperate lanes?

your telling me all 4 16x are linked and no matter what slot i install a second pci-e it will take lanes from the original 16x1 meant for the graphics card?

It means, if you put your GPU in 16_1, don't put anything at all in 8_1 to ensure you get all 16 lanes to the GPU, you can still use 16_2 and 8_2 (either 16 lanes to 16_2 or 8 lanes to both slots).

So none of the Gigabyte boards are using UEFI :confused:

From what I read yes. 32MBit flash CMOS chips according to the specs:

1. 2 x 32 Mbit flash
2. Use of licensed AWARD BIOS
3. Support for DualBIOS™
4. PnP 1.0a, DMI 2.0, SM BIOS 2.4, ACPI 1.0b

Apparently you can choose between UEFI or BIOS. I'm sure someone who has actually seen one can confirm if I'm wrong...;)
 
I thought I read somewhere that Gigabyte will be using a legacy Award BIOS still but the hardware is there for a UEFI bios should they want to use it.

Sadly no. :(

I've read that they pleaded with Intel to allow them to stay on BIOS for some odd reason despite the fact it is legacy and is EOL.

Good shout Gigabyte! I don't want a flashy clever bios system, I want a simple reliable one. The first generation of UEFI is unlikely to be faultless.

So a stable reliable bios at release and the maybe later on they can release a uefi bios to flash too?.

Sounds okay to me.
