| Post subject: | 5750 giving me grief. |
Friend has been using the ATI 5750 that Ibrin was nice enough to give me. It' s been working great for months. Today i got my 6950, replacing my 5870, which I put into friends' computer, and put the 5750 in my newly-built HTPC. No signal. No matter what I do, I cannto get the 5750 to display anything. Unfortunately there's no speaker in the case, so I cannot listen for error beep codes. It's getting power - i can see the fan spinning. However, two other cards work in the HTPC; my old 5870 and his old 250GTS. Both spit out a signal just fine, see POST info, no issue. Put the 5750 back in friends' case, and it still works fine - POSTS, etc. is peachy. I put the 5750 back in my HTPC and.... nothing. Again. I tried 5 cables over three different outputs. Nothing. I tried other PSU cables. Nothing. I cleared CMOS. Nothing. The motherboard (a DFI P35-T2RL) has the latest BIOS. I KNOW the rest of the components work, because about a week ago, I had started to install Windows on when the fan on the 250gts started making death rattles. So i shut it off before it got worse. I can start installing again with the other cards i tried. So the mobo works, the 5750 works, but not together. Pretty odd, since the 5870 never had an issue. The only thing i can think of is that my friends' monitor always ran at 75hz, but my LCD runs at 60hz, though it doesn't display "Signal out of Range". A message i've seen it display before. I also connected it to the VGA (using DVI-VGA adapter), and HDMI on my 120hz LED television. I'm stumped. I can use my 5870 in the HTPC case, but that's quite the waste of GPU power. My friend could use it much more. And being quiet, lwoer in power draw, adn 4.5" shorter, the 5750 is ideal for HTPC. Anyone have any ideas? |

Are you sure you haven't accidentaly pulled some other power cable from a vital component? CPU, MB If it was a frequency issue it would still boot to BIOS and only when the drivers are loaded it would get problems. I really don't like giving pros advice but sometimes we overlook the simplest of things. If nothing else works try the minimal startup thing? Disconnect everything not needed and add one by one other components. |

Does the 5750 have PCI-e power? I believe they all "need" it, just making sure. My guess might also be to check if the BIOS for the board has an option to limit the PCI-e power. See if that is set lower than the default 75w. I believe the DFI nF4 boards had an option to change the max wattage of the slots, maybe the P35 one does to. Might be that. But other than that, I am not sure :( |

Yepp, the power is present, and works with the other cards. I plugged in teh 250 again and the only PCI-E settings was for version compliance: 1.0 or 1.0a. It's set to 1.0a by default, but i tried 1.0 anyway, with no luck. It's a PCI-E 2.0 cards, but then, so are the other two that work. So i dunno.. i guess I'll have to keep my 5870 in there. Or con room mate into swapping machines. The HTPC is superior anyway, so he may go for it. Edit: trading it to and out-of-town buddy for a 1gb 9800gt. No audio, and a bit of a down-grade, but as long as it plays all media, thats good enough. Thanks fot eh suggestions, guys. Update: The 9800 is quite sufficient for the HTPC, and that 5750 works fine for the guy i traded it to. ...weird. |
