Hello folks - its been a couple of days since I got my hands on my new Gigabyte GTX 460 (1 GB). This was supposed to be my big upgrade - moving up from my old ATI X1800 GTO video card. I have an ASUS P5NE SLI motherboard and have Windows 7 64 bit running on my system.
Problem is - no matter what I do, there is no display out of the GTX 460 card. I have been trolling the net in vain all day today after trying everything that my friend and I knew. We have verified that the entire rig works - I can still use my old Radeon X1800 GTO card and get into Windows.
Thinking that this might be because of an older version of the BIOS, I even flashed it to the latest BIOS version - 1406. Still no luck. And now we are out of ideas.
Oh and by the way the power supply is a Coolermaster GX 550 and it exceeds the minimum requirements for the card. Any help or thoughts are most welcome at this point......
-
Firstly that main thing that springs to mind is the PSU. Now I know you said it exceeds the power requirements but how long have you had it? After a while the power output drops as you get capacitor droop etc.
-
Well, I got it this Sunday :). So, there should be no power output drop or anything like that.
The thing is - with this same power supply the X1800 GTO boots up. Not that that card needs this hefty a power supply but still....
And now I am out of ideas - especially after the BIOS update, which I did after much hesitation.
-
It's just that it is the obvious solution to your problem. You have made sure that you have connected the cards power supply plugs?
-
Yes both the 6 pin connectors are plugged in. Any other thoughts?
-
What is the exact model number of the card?
Have you tried on the ASUS forum for your motherboard?
-
The exact model number is GV-N460OC-1GI.
And no, I have not gone to the ASUS forums. Partly because I have a bad feeling about the response (or lack thereof) from there. Last time I had issues with my ASUS Xonar D2X - I had to solve them myself. No support was forthcoming from there.
-
Right give me a couple of minutes to check the manual
-
Well after a quick read of the manual there is nothing that stands out as the problem. However let's just check some details:
Have you made sure the card is firmly seated in the slot?
Are you sure that you installed the 64bit version of the drivers?
You have the card installed in the PCIe x16 slot?
The power connectors are fitted tightly?
What output are you trying to use? and what cables are attached?
-
Appreciate your effort sincerely, Dark Mantis.
Yes to all your questions. And I am using the DVI-D output. But I also tried out the mini-HDMI output - with the same results. In every case, the computer boots in and goes past the BIOS. My keyboard is fully responding. It is just that the display does not come up.
And with the same rig, the display comes up when I use my old ATI Radeon card.
-
The only other thing that may need doing is updating the firmware on the board. This should be available on the download section of the Gigabyte website.

-
Well, I have downloaded the latest version of the drivers - 258.96. But as far as I can see there is not much I can do with the file until I get the display running. Is that correct?
Also does the fact that I have been running an ATI card already on the rig have anything to do with this strange behaviour?
-
Ah! Have you cleared your CMOS and then loaded the BIOS optimised defaults? There is a FAQ on how to do it in the FAQ section of the forum.
-
Yes - when I flashed the new BIOS - the procedure made me do it. After flashing the bios I did reset everything to default.
-
Not just reset your BIOS. Clearing the CMOS is a different thing.
-
Yes. I understand. I did clear the CMOS before doing the BIOS flash. Do I need to clear the CMOS again?
-
Yes I would advise it because it cant do any harm and it could just be the root of your problem. The BIOS is just like a translator between the hardware and the software, the CMOS is a list of all your hardware that is installed. The BIOS is about 8Mb in size but when you update it you only update about 1Mb.
-
OK just finished doing it. No luck :(.
Still - I see that the entire rig works - just that the display does not come up.
-
Are you using the same cable as on the other card?
-
I will be back in one hour approx.
-
Are you using the same cable as on the other card?
Yes - the same cables, the same monitor and the same everything actually.
Only difference is the Radeon does not need 2 of the 6 pin cables. The NVidia needs them. Other than that, there is nothing which is different. And the Radeon gives me display.
I am worried whether the new NVidia could turn out to be faulty. I cannot make anything out on the surface or on the packing. It appeared to arrive in very good condition. And when I switch the machine on, the video card funs churn at good speed.
Its late in the night here. I will check back here tomorrow morning. Appreciate your assistance - Dark Mantis!
-
Well in that case I would either suspect the PSU or the graphics card. It could be either. Can you check the card in another computer? I fit works then it is down to the PSU not being powerfull enough. If you have to swap it out make sure that you get a good quality one with a single 12v line of at least 70amps.

I actually made sure that the specifications of the PSU are such that it will not be overwhelmed by the graphics card. The Coolermaster GX 550 does have more than enough amperage on the 12V rail than the GTX 460 demands. So, I am not sure that it is the PSU which is at fault here.
I will have to try and see if I can test the card out in another computer. Let me see if I can do that tomorrow and get back here with the results.
-
Yes by all means make sure that it is not the card at fault first. However if it is not the case I would be very surprised if the PSU didn't turn out to be the culprit ;)
I have just been checking the specs on your power supply and although the advertising looks good when you actually get down to numbers they are not brilliant. The efficiency drops off considerably after just a 60% loading and the 12v rail is only 40 amps which isn't bad but not enormous.
Can you also list all of your hardware that you are using so that I have a better idea of the loadings etc.

When U say"Computer gets past the bios" where exactly does it go "Blank"?
Do U see the "Verifying DMI Pool Data....." part?

I should have clarified. I see nothing at all on the monitor. Not the stuff that comes before POSTING or anything at all. But I am saying that the system booted up based on the speaker output and the keyboard response.
-
Sorry if I'm hijacking your thread.
I have a similar (if not identical) problem. I got my two Gigabyte GTX460 yesterday and installed them in SLI and powered by my week old Seasonic X-750.
On cold boot up I get no display but the computer seems to load to win 7's login screen. If I leave the computer on for a few minutes and restart it works normally. I read that Gigabyte recalled the first cards because of issues when these cards were too cold but I thought when I ordered my cards last week that they would be of the new batch?
-
Does it make any difference if you boot with just one card?

Not yet, I will try that tomorrow after work since the system cannot be warm.

Folks the issue was sorted out thanks to the friendly and knowledgeable guys at 'TheITDepot' (a local tech shop) here. Yes, I felt sheepish resorting to the technical people despite having the benefit of the worldwide web and not to mention the fact that I am myself in the IT business. But well - sometimes you need a fresh perspective. This turned out to be one of those cases.
The problem was - the card was somehow being shorted on contact with the case as well as the 2 screws that were being used to attach it to the case. Yes - very strange. But hey - it happened to me.
Although part of the mistake can be explained when I point out that I did not really nail down all the screws for the motherboard (to affix with the case). Still, it was not as if the issue went away once the motherboard was completely screwed in.
Finally we used plastic thumbscrews to secure the Graphics card to the case and that was that....
Enkal - I dont think this might be a solution which would be common. But just for what it is worth you could try and see if it is a shorting problem by assembling the entire setup on a flat cardboard surface - away from the case, to see if it makes a difference.
Thanks folks for all the replies. In particular Dark Mantis!
-
you are more than welcome Vortex. I am just glad that you managed to get it sorted out finally. Personally I think from your experience that there probably is something wrong with the card because it should be able to be screwed to the case with metal screws no problem. ??? It sounds to me as if the card has a short to earth on it. Anyway at least it is working. ;D Have fun my friend at last ;)

Swapped cards, no difference. Reset BIOS with the cards swapped and it works, only difference is that windows wont detect the 2nd card now so now SLI for me. I will swap cards again and try. :(
Ok swapped back the cards, same issue. On cold start (graphics card is cold) I get no display at all. If I let the computer run for a minute then I shut it off and on again the card works normally. It really feels like I got one of those bad cards that Gigabyte recalled.
-
It certainly does sound like it. RMA it and make sure.

Yea I'm afraid so.. :( In 14 years of building my own computers this will (probably) be my first RMA.. it's a sad day. :P
-
To be fair then you have got away lightly until now. ;) Most of us have had a few items that were faulty.

Lots of research, buying quality brands and no impulse buying reduces potential problems imho.
I have sent out some tech support requests about this card now, will probably take some time before I get any replies though. Are there any Gigabyte reps on these forums btw? I havent seen anyone with that info in their avatar?
-
There is a Gigbyte representative on the forum called "runn3R". He's the moderator but he's away on holiday for a couple of weeks.

Ahh, thank you! I do hope my issue will be resolved before he comes back though. ;)
-
Not to be too depressing but I doubt it ::) The tech support team are very slow at responding in general even though we at the forum here field a lot of the queries and take a lot of pressure off them. I think it just lets them think they can take it easier. >:(
-
I've asked for a RMA-number (not sure of the english nomenclature here) and a replacement from the store I bought them from. Luckily one of the cards works fine so it's still an upgrade over my old GTX 260. :)
-
You got it quite correct ;D So you will keep one card and exchange the other for a new one, that's good. As you say even with one in it is an upgrade.
-
I was tracking the package as it went back to the store. Two hours after they received it I got a mail that they are shipping me a replacement card! ;D
And all these stories I've heard about people waiting for weeks for RMA stuffs.. guess I got a lucky first! ;)
-
It's good to hear a nice ending with good service by the retailer. Have you had a chance to try the card yet?

It was shipped today so I wont have it until early next week I guess. Once everything works fine I'll try some mild overclocking since most of these cards seem to be able to hit 800MHz core clock easily. :)
-
Trying the cards out now, the new card shows on average 5-10 degrees warmer than the old one. I put the new card in the middle slot on my mobo and there's nothing under it. I wonder if that is due to different revisions of the card?
-
Possibly different cards behave differently the same as CPUs and memory. It may just be settling down and will drop a few degrees. The main thing is it's working ;D

True! It's my first SLI-setup so I wasnt sure what to expect.
