Gigabyte Z77-D3H Owners, Which Graphic cards you have?

Resurrecting this thread for Giga-Man's attention, have trust mailed you too chap.

Another one having problems with the D3H, GPU (570GTX) running at x4 and I can only set AUTO/x1/x4 against the slot in the BIOS. If I force Gen2, the machine fails to detect the GPU and boots headless (or using internal HD4000).

Forced the Render Test in GPUZ and the card hits a ceiling at x4, it'll down speed to x1 quite happily but that's about it.

Card is made by MSI if that's any difference, and CPU is i5 3570K. I've disabled anything that might be using a PCI-E lane and that makes no difference either.

Noticed F19 beta is out, but can't find any helpful release notes.
 
Try latest beta first,if it doesn't fix your issue you can always flash back,ill pass on the problem to the BIOS engineers,you can also email gigabyte yourself and tell them the problem,I'm guessing its a BIOS problem
 
The plot thickens.

Thought I'd RDP into the machine once it had booted with no display to see what was going on. Turned up something fairly interesting once I got into Device Manager...

Presumably this is happening at a lower level than Windows, and it's getting assigned nothing by the BIOS on POST so hence no display.

Don't forget this is with USB3/LAN etc. disabled in the BIOS so there should be more than enough resources to give to the primary graphics PCI-E slot...!

How does this stuff get through hardware testing? I mean really, it's weak beyond reproach!
 
try this suggested by dkt70

wazza300,
Maybe not a fix, but worth a try, perhaps.

A mate of mine had a similar problem with a 560Ti. He fixed his x4 -x1 drops by getting the latest BIOS, uninstalling his nvidia drivers (this was a few months ago, so we're talking 3.0xx drivers), put the BIOS on a flash drive then shut down the PC and remove the 560 and put it in the slowest bottom slot. Reboot PC straight into BIOS, update BIOS, shut down PC, back in BIOS and reset defaults, shut down PC again and unplug from wall socket. Remove 560ti and pop it back in the top fastest PCI-e slot and boot back into BIOS, re-do personal settings, boot into Windows, update drivers to latest at the time, and voilà - Working 560Ti.

A lot of hassle, I know, but it fixed his. Heck, he might have just been lucky, but he was getting desperate and was willing to try anything.

Good luck.

BTW, that latest F19d BIOS, as far as I could tell, didn't do anything for me, maybe even worse. The only upside was the nicer BIOS fullscreen logo, which says it all really.

worth a try even if its a lot of faffing:confused:

from the above its looking like a pci slot/switch detection bug,it has a switch that auto detects a gpu/pci lane speed
 
I can put give it a go I guess, I'll try it out tomorrow when I'm more alert and less full of wine. :D Thanks for passing the info on.

So this switch bug, second time I've seen it mentioned now. Is this something that can be fixed with a BIOS update, or am I going to have to RMA the board? :(
 
idk,it could just be a detection problem and by doing what they have done has fixed it,if the switch itself is faulty then rma would be needed,try the above tomorrow first though,it still could be bios bug with that make/model of gpu aswell
 
I'm gonna raise this as a fault with Gigabyte I think, get their take on it.

Even if the above works, I really shouldn't have to be jumping through all these hoops to get a graphics card a) working and it b) in a stable fashion.

I'll do it to prove it out though, I think we've done enough diagnostics for their support department mind. :D
 
Just built my new system this week using the Z77X-D3H - so far everything is working fine.

i5 3570k
Z77X-D3H
8GB (2x4) Corsair XMS 3
Sapphire 6870
Coolermaster 600w Silent Pro

Board: Rev 1.0 (4pin)
PCI-E: Running at x16 according to GPU-Z
Bios Version - f16 (I flashed during build)

BIOS showing three options for me Auto, x4 & x1 - Manual doesn't list x16 as an option.
