I'm going to go insane, MSI Z68A-GD80 (G3)

HNR1 · 19 Aug 2011 at 22:34

What the **** is wrong with this mobo, it's the buggiest BIOS i've ever met, i don't think i want to meet it ever again on a dark night.

There is no mouse control, the click bios 2 says it doesn't support my main board :eek:

I've done updates via the live update, no better.

But the worse thing is both my gpu's are running @ x8

Anyone got any suggestions?

Thats normal for almost all socket 1155 boards unless they feature an additional chip to boost the lane count.

There is no mouse control,

Try a different mouse/USB port?

Is this good or bad?

You can't navigate the bios, the mouse is fine in windows, so we will strike the info off.

The mobo runs 3x @x16

now i'm crying

You win.

Slots
2x PCIe 3.0 x16 slots (PCI_E2, PCI_E4)
1x PCIe 2.0 x16 slot (PCI_E5)
PCI_E2 supports up to PCIe x16 speed (when PCI_E4 is empty) or PCIe x8 speed (when PCI_E4 is installed)
PCI_E4 supports up to PCIe x8 speed
PCI_E5 supports up to PCIe x4 speed

I don't even have 1 running @ x16, in theory there are 3 x16 slots so says the manual.

I'd be happy if just 2 ran @16 or even 1.

So you are saying they'll both only run @ X8

When you have one card installed in PCI_E2 (the first Blue slot from the top) PCI_E1 being the little Black one above it, on its own with no other cards installed it operates at 16X

When you add a second card into PCI_E4 (the next Blue slot) the bandwidth is divided to 8X and 8X

Surveyor · 19 Aug 2011 at 23:16

1 card will run at x16 in slot PCI_E2.

2 cards in slots PCI_E2 and PCI_E4 will run at x8 each.

My Gigabyte P67A-UD7 does SLI x16/x16. It us 1155 chip set. So, in a word, yes.

Surveyor · 19 Aug 2011 at 23:31

The Gigabyte P67A-UD7 has an NF200 chip to provide additional PCI-E lanes.

The MSI Z68A-GD80 doesn't have an NF200 chip so is restricted to x8 with 2 cards.

You're not really losing any performance:

PCI-E x16, x8 and x4 tests

HNR1 · 20 Aug 2011 at 01:57

I will quote from MSI off the mobo info that i got with it.

3 xPCI Express x16 slots, enjoy the power of multi-graphics, more PCI-E bandwidth than other Z68 MBs

The UEFI bios is a piece of doggy doo.

I'm going to do a whole new fresh install tomorrow, as i give up with this one.

I've seen that before about the x8 tests i'll just have to put up with that

Now that's just cute, decides to share hot water bottle with them

stulid · 20 Aug 2011 at 02:00

You can quote that all you like, it doesn't change the facts that the other 16X PCI-E slots are not fully wired.

Actually look in the second Blue slot and see if the little gold fingers go all the way across it.

http://www.msi.com/product/mb/Z68A-GD80--G3-.html#?div=Detail

- PCI_E2 supports up to PCIE x16 speed when PCI_E4 is empty, or PCI_E2 will support up to PCIE x8 speed when PCI_E4 is installed
- PCI_E4 supports up to PCIE x8 speed

Wonders about the little black one that's all alone.

Looks at enlarged picture. It's blue and it's a slot, can't see gold fingers.

*hilarity ensues*

stulid · 20 Aug 2011 at 02:35

don't feel sorry for the little black thing, it has other coloured friends nearby.

it would be a lot worse if it was sandwiched between the two large black things.

Surveyor · 20 Aug 2011 at 02:51

If you look at the rear of the motherboard you can see that PCI_E2 is fully connected, PCI_E4 only has connections for x8 and PCI_5 only has connections for x4.

When cards are installed in both PCI_E2 and PCI_E4 half the connections for PCI_E2 are disabled to supply the bandwidth for PCI_E4.
