Hi
I'm doing a new build with a GA-880GA-UD3H, I've put everything together and just connected an old LCD monitor using the mobo VGA port. I have my HD5770 installed but no monitor connected to it yet. No O/S installed yet.
Couple of questions:
1. When I do a cold boot all is OK and I've successfully run a few passes of Memtest86+, but if I reboot or do a warm boot it boots OK (1 beep from speaker) but I get no video - it's not that the monitor is not getting a signla, just that it's blank. If I turn the PC off and leave it for a while then I get the mobo splash screen. Does this signify a problem?
2. When I plug monitors into the HD5770 DVI ports do I need to set something in BIOS to disable the mobo graphics or will the fact nothing will be plugged into any mobo graphics ports effectively disable it? (can't find any answer in mobo manual)
Other components are
AMD Phenom II X4 965 Black Edition
2 x Kingston 4GB (2x2GB) DDR3 1333MHz HyperX Blu Memory Kit CL9 1.5V Non-ECC Unbuffered
Sapphire HD 5770 1GB GDDR5
Thermaltake Armor A60 Mid Tower Case
Samsung HD103SJ Spinpoint F3
OCZ ModXStream Pro 600W - 80+ & SLI Certified - ATX12V 2.2/ EPS12V
Will be attaching two monitors into the HD5770 DVI ports
Thanks in advance

It is always best to disable the on-board graphics if you are using an add-on card as it frees up RAM that would otherwise be taken.
In BIOS you need to change the settings under IGX Configuration. You can find this under the M.I.T section or the Advanced BIOS Features. Disable the internal Graphics Mode and then set INIT Display First to PEG. Pages 38 & 46 in your manual. Hard to find as you probably weren't looking for IGX!
Once you have made the changes to BIOS you will need to make sure you have attached a monitor to the 5770.
You haven't said what revision number your motherboard is or what BIOS version you are running but I would check to see if there is a BIOS update for your board before thinking there was a problem with the hardware.
-
Thanks for the prompt advice
It was in the act of trying to get into the BIOS screen to see the board/BIOS revision numbers that I found this problem.
In fact I have cold booted this morning and there is no action on the VGA monitor at all, will have to try DVI on the mobo or GPU
-
Hi again,
If you are still having problems after trying to connect the monitor via a different port then I would suggest building the PC outside of the case. Use the box that the motherboard came in so that it doesn't short out.
Remove everything except for the CPU and 1 stick of RAM and connect the monitor to the motherboard and only attach your keyboard. You will also need to attach the power leads and the switch cables from your PC Case before you can start it up but then try and see what happens. If you still get no image on the screen try clearing CMOS (check this thread: http://forum.giga-byte.co.uk/index.php/topic,2286.0.html ) and then try again.
If you look at the bottom left hand edge/corner of the motherboard you will find the Rev no printed there, it is also on the box label.
-
OK, will give this a try.
The board is rev 2.1
Thanks

I have connected a different monitor to the DVI port on the motherboard and still get no display at all, just a black screen.
I changed connection to the GPU DVI port and booted and got display OK, I went into the BIOS and selected "Load Optimised Defaults" just in case one of the few options I'd changed when I successfully had a display yesterday had had an affect.
Then I swapped the monitor back to the Mobo DVI port and booted, still no display
Swapped back to GPU DVI port and managed to get the BIOS revision number from the post screen - F3
I'll take the side panel off and take out the GPU (it's covering the CMOS reset) and try a CMOS reset and check display on mobo DVI.
If no improvement I'll try taking the battery out for 10 mins and try again.
If no improvement I'll try taking the mobo outside the case and starting up as you suggested.
Modified 14:27
Just one thing, my case came with 5 or 6 built-in stand-offs and some screw-in standoffs. I put the screw-in stand-offs under the right locations for the 9 screw-holes in the mobo but then discovered that the case only came with 8 mobo screws (as specified in handbook), so I simply left the centre stand-off in pace but didn't put a screw in it. This couldn't be having an unexpected affect?
-
Just to save you a bit of time taking out the GPU just try removing the battery instead if thats easier.
-
Just a quick thought,
You're not trying to connect your monitor via DVI with a D-Sub adaptor are you? The On-board graphics doesn't support this method of connection.
In BIOS try setting the Onboard VGA output connect as D-SUB/DVI Sets the D-SUB/DVI-D as the graphics display rather than leaving it at AUTO.
Being totally honest, as you are using a 5770 I would not get too hung up over this issue and I would just disable the On-board graphics and go with the 5770 as you're getting an output from that.
-
@DarkMantis - GPU was also covering the battery - have just removed it so now might as well go ahead and clear CMOS
@absic - no I'm using a proper DVI cable on this monitor and had a VGA cable on the other one
Had thought about just ignoring this but do feel it's very handy to have a default video capability in case of issues with the GPU at some time, and if there is a hardware issue it might cause other problems later on.
BIOS vsn is F3 - do I need to update this?
update 14:50 - cable details - it's same cable when connected to GPU
Plexus DVI-D Dual Link Flat Panel Replacement Cable (Black) 3m
-
OK, cleared CMOS and started up without GPU, using DVI.
Now getting a display ;D - have reloaded optimised defaults.
Will turn off and replace GPU and try mobo display again
-
Yes, I agree about having a back-up video source and I'm pleased it now seems to be working again.
I would bring your BIOS up to date as sometimes, although it isn't mentioned, the updates can address problems with the video.
-
well, I've put the GPU back in and now the mobo display is blank again
I will go back to the GPU display and check the setting you mentioned above.
If I can't get the mobo display to work I'll presume it's a conflict with the GPU and install Win7(64) and check everything else works.
Thanks for your advice, been invaluable
-
If I can't get the mobo display to work I'll presume it's a conflict with the GPU
I was just thinking the same thing and was looking through the manual for your Mobo to see if that is mentioned...... it's not.
I would remove the 5770 and update BIOS using QFlash then after I had completed that procedure I would try again with the 5770 on-board. If still no luck I would disable the On-board graphics and carry on but, I would also contact GTTS and make them aware of the problem.
-
Tried setting the Onboard VGA output connect as D-SUB/DVI - no difference
Will think about flashing BIOS, would prefer not to if I don't absolutely need to.
-
OK I understand.
So, as the problem only occurs when you plug in the 5770 it would seem there is a conflict of some sort between the 5770 and on-board graphics chip.
As you are only going to use the 5770 for your graphics output you can safely disable the on-board chip. You know it will workif needed but that you will have to remove the 5770 first.
That way you shouldn't need to update BIOS if you don't want to but it isn't really that difficult to do and it could resolve this problem, although there is no guarantee of that.
-
I have similar problem as you, while my pc doesn't plug display card
during BIOS post screen and Windows loading screen, onboard dvi won't output
after reached Windows logon screen, the dvi will function back.
Tried with Clear CMOS and load optimized setting, but the dvi still shows nothing,
I am using rev2.1 and F6 bios revision, what can i do now?

I'm having more problems with my new build.
On booting I was getting display via the HD5770 with no problem, have been able to reboot nuerous times and install WIn7(64) and various software.
Yesterday on cold-booting I had a blank display again (monitor plugged into the HD5770 and the on-board graphics are disabled), on hitting reset I get display (though gadgets that should be on far right have screen are central, indicating that when I couldn't see a display it was in the wrong resolution).
Same thing this morning, on cold-boot no display and this time I noticed the POST beep - one long and one short.
I guess it's time to flash the mobo from F3 to F7 to see if this resolves these issues?
Have read the helpful posts about flashing using Q-Flah, just one question. The F7 download included three files, the new BIOS file 88GAUD32.F7 plus two others - a bat file and an EXE - I presume I don't need these two other files for Q-Flash?
-
Hi,
you're correct you don't really need the other two files but I always copy all of them onto my USB stick, just to be sure!
-
right, BIOS successfully flashed to F7
PC powered down, will have lunch then power up and see what happens.
-
If it powers up OK and you can see your monitor, don't forget to load Optimized Defaults then reboot before you make any changes to BIOS that you need.
-
Aye, I've reloaded optimised settings as part of the flashing process.
After being powered-off for about 30 minutes it powered up OK, however these problems with blank display seem to be developing over time rather than being immediately apparent, so might not know for a few days whether all is definitely OK or not
Feel sure I have the latest drivers for HD5770 but will check that as well.
-
Turned PC on this morning, only one short beep when booting to imply successful boot but still blank monitor :(
I'm booting into Memtest+86 so that I can wait a minute then hit Esc to reboot, and up comes the mobo splash screen and Memtest display is showing.
So now I need to prove it's the Mobo at fault I guess.
Currently I've taken out 3 sticks of RAM and am running Memtest, will put each of them back one-at-a-time in their relative slots and test each one for up to 2 hours.
Then I'll swap monitors just to be sure it isn't related to that. See what happens when I cold boot.
Then I'll swap back to onboard graphics and remove the GPU. See what happens when I cold boot.
I bought all my kit from ebuyer, wonder if it's worth my while contacting them toflag up tat I'm having issues and am trying to figure out where the problem lies?
-
Hi,
Sorry to see that you are still having issues but I think you are doing the right thing trying to find where the problem actually lies.
I would contact e-buyer and tell them that you are having problems and also what you are doing to try and resolve them so that they are aware of the situation. It should make it easier if it comes to RMA'ing any of the parts.

It is always best to disable the on-board graphics if you are using an add-on card as it frees up RAM that would otherwise be taken.
In BIOS you need to change the settings under IGX Configuration. You can find this under the M.I.T section or the Advanced BIOS Features. Disable the internal Graphics Mode
Wow, is that right? So the reported "shared video memory" is just wasted, if you have an add-on card?
and then set INIT Display First to PEG.
This is what I had done. Actually, I had it set to PCI at first, until I read the docs and realized PEG was pointing at the x16 slot. Is there a "practical" difference between PCI and PEG, or is PEG simply more specific and what would've happened anyway?
-
OK - I've run each RAM stick through Memtest86+ v4.10 - 4 passes each no errors reported.
I've put them all back in and switched to a different monitor also connected via DVI, took me about 20 mins to set this up and on first boot I had blank display. Rebooted and was able to get into BIOS and enable onChip graphics and connect monitor to onChip DVI. Has worked on every boot/reboot since. First time I've tried onChip graphics since flashing the BIOS.
Next step is to re-attach to the GPU and see what happens when I boot it tomorrow morning.
I plan to leave the onCHip graphics enabled and set INIT DISPLAY to PEG (it's working for KEP)
Just to confirm - I do have my GPU inserted into the PCI-Express x16 slot
I'll leave all other BIOS settings as per optimised settings.
Time for a drink ;)
-
I'm hoping that I have fnally got to the bottom of this, I think it's the combination of which port I have the monitor plugged into, and the BIOS settings for graphics adapters. I had assumed that the words "Init display first" on the BIOS setting meant it would try one then the next and so on. Instead I think it means that if you have multiple displays, whichever you select here will be treated as primary monitor, anything else plugged-in will be secondary. What appears to happen is that if you select something here that relates to a graphics port with no monitor attached, it looks no further.
Extra confusion has been added by:
- "load optimised settings" sets the BIOS to a combination of settings such that I will get a blank display if my monitor is plugged into any of the onboard graphics ports (so would "load fail-safe") because "PCI" is the default
- having said the above, when I first booted the system after assembly, I got a display, it was only on subsequent boots that I had problems, I have no explanation for this
- one day booting gave me an error beep code every time, seems to have been fixed by flashing the BIOS to F7, so I'm going to ignore that it ever happened
I've done some experiments with settings this morning, booting into Memtest on CDROM, hoping this wee table will make sense:
BIOS option setting combinations tested
combo1 combo2 combo3
Internal Graphics Mode UMA Disabled UMA
Onboard VGA Output Auto - Auto
Init Display First PCI PEG OnChip
Results were:
Monitor connect to GPU DVI OK OK Blank
Monitor connect to OnBoard DVI Blank - OK
I currently have it set to "combo2" above and will reboot periodically through the day and see if there are any failures.
Must remember if loading optimised settings, to rejig the graphics setttings !
-
Just wanted to update this and say that since I've set the BIOS options as per my last post I've had no issues with blank display. 8)
Thanks guys for your help and advice with this. :)
