I'm building a new system with ga-z77x-ud5h and xfx-R7850 DD.

I cant get the graphics card to work. I can get signal from internal graphics from MB, but no signal from the XFX on PCIe x16.

In BIOS i have tried disabling the internal graphics, but then i get no graphics (not in BIOS, not in windows).
I've tried setting the bios to use 'PEG' (PCI express Graphics) first, PCI first, internal first and auto. No signal on XFX in either case.

I've connected the to PCIe extra power cables, and even the SATA extra power coupling on the MB. No dice, still no signal on XFX.

I've tried placing the XFX in my old computer (Gigabyte GA-MA790X-UD3P + AMD Phenom X4 9650), Voila! Graphics no worries, BIOS and Windows!

I've tried my old graphics (Radeon HD 4890 1) in new computer, and voila! Graphics.

I've tried putting the XFX in PCIe x8 and x4. No luck.

Getting frustrated here. Any suggestions?

System:
Intel Core i7-3770K Ivy Bridge
GIGABYTE GA-Z77X-UD5H (rev. 1.0)
XFX Radeon HD7850 (2GB)
Corsair 16GB DDR3 1600MHz
Intel 330 Series 120GB SSD
 
Solution
Sounds like a defective HD7850 then.

BTW, some video cards ship with adapter cables that can be used to convert an old style 4-pin molex connector to a PCIe connector. Not a concern here.

I suggest returning/exchanging the video card.

Good luck!
Just a fast note before I leave for work. This is the second mobo (same model) I've been through. First one did nothing but cycle power and code 19. That's just using the onboard vid. Didn't even get a POST. RMA'd that one and now this, not much better but at least it POSTed and was able to use the onboard. Just ran down and bought an MSI mobo to swap out. I'll let you know what happens in the next day or so. My previous old mobo was Gigabyte (6yrs) and had no probs until I broke off a capacitor. Now this. Doh!
 
Well, here's the results. Swapped mobo's to the new MSI GD65. Installed everything incl gtx560. Although, first using onboard vid just to make sure of the system POST. Powered up and BAM! straight into the BIO config on first boot. Tweaked a couple simple items, date/time, temp control, etc. The video was already set to PEG, so I figured save and reboot. Booted straight into the Ubuntu, no prob.
Shutdown, swapped vid connections to the 560 and powered up. No problems into the OS. :))

I yelled ya bitches...that's what a mobo is supposed to do!

So it looks like gigabyte may have some issues somewhere (bios firmware, or poss bad batch of chips) that is causing incompatibility. I hope they find it soon. I do like gigabyte products but two mobo's and still not working has soured me for a while.

Thanks for some of the suggestions on this post. Every little bit helps.
 
Still here, just been working, so no time for messing with the computer.

Im planning to flash bios with latest bios and see if that helps, even if my bios date is 3. sept. 12.

If that doesnt work, im calling the shop to see if i can get any refund or something. Just a bit in doubt whether to to try another HD78xx series og go for 560 ti.

I'll return with reuslts of BIOS flash.
 

Try the BIOS update first. As pointed out, a completely different GPU had the same issue.

I would engage Gigabyte directly for help AND/OR exchange the mobo for another at this point. Current analysis would point to the mobo as the problem and not the GPU.
 
No dice. Flashed F14, but still no videooutput from the new graphics card.

Frustrating. Hoped BIOS flash would do the trick since F13 "improves VGA compatability".

I'm being pessimistic about contacting Gigabyte, since they'll probably claim it must be the GFX-card and XFX will claim its the MB. I bought them together at the same seller, and besides in Denmark its the seller that must provide support and/or exchange the product, but I, the buyer, must prove the fault. So i'm not hopeful about getting a refund from either.

Guess i'll check the market out for MBs (since it was the cheaper part).

The Z77 motherboard review (http://www.tomshardware.com/reviews/z77-extreme6-z77a-gd65-z77h2-a2x,3187-22.html) makes me consider the ASRock Z77 Extreme6 (since Biostar isn't sold in Denmark).

Thx for the inputs.
 
Take it to them and show them that it doesn't work. Also tell them you know someone else that had the same problem with a 560ti and they changed to a different motherboard and it works.

They should be able to swap you a different board, if not, never buy anything from them again.

Asrock is way better than Biostar.
 
Update:

Got the ASrock z77 Extreme6 this morning (paid extra to get it delivered on a saturday).

I installed the MB and booted the system while holding my breath... No dice. Still no graphics output in discrete card.
In MB system overlook it didn't detect the card.

I noticed that when i selected PCIe2 (thats the x16 slot) link speed gen 1 i could detect the discrete card and there was graphics output on it.
Since i wasn't about to run my new graphics card in gen 1 i tried flashing to latest BIOS... Now it wouldn't boot if i selected anything but 'auto' in PCIe2 link speed.

For good measure i tried it in PCIe x8 slot, but to no avail.

At that point i was more or less in homicidal mode. After cooling down (no deaths in the neighborhood, not even small pets, hell even GFs feelings were left unmolested), i've decided to try once again by buying another GFX-card.

Before i buy a new GFX card (considering a GTX 660 to switch category) i have a question;

Can i be certain that it's the GFX card thats to blame now? As i understand (and its right on my edge of understanding) the CPU does have something to say now with PCIe ports. Or have i misunderstood? Can it be the CPU thats somehow defect, and i'll have the same issue with my new GFX card?
 
just found this post. I have the UD5H board with XFX 7850 GPU. Well, i am on my second GPU. Same issues - the new system worked great for 3 weeks then poof - no signal to the monitor. Thought it was the GPU and RMAd for another. In the mean time popped in an old GTX 9800 and it worked great. Integrated graphics worked too. Got my GPU back and popped it in...nothing. I called Gigabyte. The tech told me the bios settings to use (I was already using them). He said send the mobo in for warranty repair. I finally got so frustrated i took the whole system to a computer repair shop. Shop said that the PCI slot had an issue - either a short or voltage problems. He thinks it fried both my GPUs (he popped in a GTX 640 and it fried his too).

Now i am sending back my mobo and my refurbed GPU. Just bought an ASUS mobo. will use the repaired Gigabyte on my next build. Seems like a great board but it definately has issues.

Board: Rev 1.1 and Bios F14

Gigabyte Z77X-UD5H
I5 3570K CPU
XFX HD 7850 2 gig GPU
Samsung 840 pro SSD 128gig
WD 1T 7200 RPM HDD
Corsair Vengence Ram
 
Was hoping to re-spark this conversation...still looking for answers if anyone can help.

I am on my 4th graphics card and 2nd mobo now. Still having the same issues. Gigabyte tested first board and says nothing is wrong but sent me a replacement board after a lot of resistance and hassle.

Just installed my 4th replacement on the GPU. The oddity of it is that i get signal for a week or two with no problems. Then the screen goes black and I restart the computer a few times and it works. Then, i will get the final black sceen with no signal and it is done. Very frustrating and still no solution.

Everything on the latest has been replaced:
GPU - 4th replacement of the same model
CPU - brand new (same model
mobo - 2nd replacement of the same model
PSU - brand new
ram - the only thing that has not been replaced

Can ram cause issues with the signal from the GPU, or can if affect the GPU??
