New 5670 won't post

Am now on my 2nd 5670 (tried 2 different models) and in neither of my machines will they properly boot with the card installed.

In the first box (my HTPC) using an old MSI K8NGM2-FID motherboard, I don't even get any POST beeps, fans spin up but nothing else.

In my main gaming machine, using an ASUS P5N-E mobo it will partially boot but with a blank screen, appear to reset itself, try again and usually on the 3rd attempt windows 7 will load.

As mentioned have tried 2 different 5670s to rule the card out as an issue, but that's left me wondering what is the problem. Could it be a PSU problem? In my main machine there is tagan 650W PSU in there, fairly recent, so again would be surprised if that was the problem.

Only thing I can think of is that the 5670 is placing quite a heavy power draw on the PCI-E slot since it doesn't have any external 12V connectors like the higher spec cards have, but this doesn't seem hugely likely either. The gaming machine runs a 4870 just fine (albeit with 2 12V connectors powering the card).

Any ideas anyone, this has got me stumped! Thanks
 
Sorry replying to my own post, but just a thought. Could this be a PCI-E 1.0 vs 2.0 problem? Am assuming the power supplied by a PCI-E 2.0 slot is greater than that from the older version.

Generally PCI-E 1.0/1.1 motherboards are still compatible with PCI-E 2.0/2.1 cards, but the card will only run at the max speed the slot can provide (sometimes halving performance compared to a motherboard with the suggested connection).

You deffinately have enough wattage on your power supply, but how many amps does it provide on the +12V rail(s). On the ATi website it suggests a power supply with at least 35 amps on the +12V rail, and 45 amps for a crossfire setup.

Could be an idea to clear the C-MOS of the motherboard, and make sure you have the latest BIOS installed for your board.
 
Thanks will try resetting the CMOS. On my HTPC, the 2 12V rails are 16A each but my understanding is you can't just add them together to get the total 12V output.

The tagan has well in excess of 35A though.
 
Hmmm, doesn't help me much then. Although the fact it's a PCI-E 2.0 (2.1?) card in a 1.0 slot can't help I would have thought.

In any event, something is badly wrong. If clearing the bios doesn't work I guess first step is replace the PSU, and then it's a full system overhaul I suppose.

Yes you are right about not adding the +12V rails together, so I think your power supply is a little underpowered. Im guessing as its HTPC it has a micro power supply??

PCI-E 2.1 is the most up to date version of the connection. Currently there are no motherboards on the market with a PCI-E 2.1 slot only 2.0. It just future proofs the cards a little more for when the boards appear.

While running that card in a 1.0 slot, the speed of it will be significantly reduced. Like you say it could be time for a system overhaul.
 
Same situation here...

<snip> MSI K8NGM2-FID motherboard, I don't even get any POST beeps, fans spin up but nothing else.

Ironically, I have the same motherboard and started scratching my head when I installed my new Sapphire HD5750 Vapor-X card. My results are the same as yours. No POST beeps, yet taking the card out and re-installing my X1300 PRO it POSTS and boots.

Tried it in another machine with an MSI K9AG NEO2-Digital board and it POSTS and windows sees a "VGA card".

Thinking maybe my power supply wasn't up to snuff (although I though at the least it would boot) I installed a Seasonic Gold X-650. Results same. No POST.

Searching around...now I see more mention of the n-force4 based mobo's having issues with HD5xxx video cards.

So...you are not alone. I'm not sure what to do at this point short of upgrading the mobo to an AM3, memory (to DDR3) and AM3 processor....
 
Don't think it will. Given how old that mobo is the last bios update for it was a couple of years ago, and I was on the latest anyway.

I ended up upgrading my whole system, £170 all in, plus the price of the card. So much for my cheap upgrade to get HD Audio bitstreaming!
 
I'm having this exact same problem with an Asus M4a78t-e and an Asus 5670. My power supply is an Antec 750w, so that's not the problem.

Any ideas??

EDIT: After researching this problem a little more it seems that some machines will simply just refuse to work with the 5670. If anybody knows why I'd be very interested! Time for the old RMA.

I had the EXACT same problem and my ASUS mobo wasnt giving the PCIE slot enough juice. I swapped it out for a new Gigabyte one and it has been fine and dandy since.

I think the 5670's are fussy as they are fully powered from the slot unlike most cards these days.

I tried all the usual bios etc.. but that didnt make any difference at all.
 
+1

As mentioned I had to upgrade my whole system in the end. Reckon it's the power draw these cards need from the pci-e slot.
 
I got the feeling ATI had bummed me slightly - its not even a decent card. I should have opted for a 5770 really.
