6950 not working

Just got myself an HIS 6950 2GB (not the ICE-Q version). Plugged in but when I boot I get absolutely no signal at all from the card.

Running on a P5K-E (oldish I know, but should still be fine), Corsair HX620W (yes both 6-pins are plugged in).

I've tried in both PCI-E slots on the MB, have tried both DVI and HDMI outputs on the card, nothing. My old 4870 still works perfectly fine in there.

Upon boot, the fan starts loud for a split second, then drops down to normal (just as my old 4870 does).

As far as I can tell, this card doesn't have any BIOS switches so can't try that. I've also reset the BIOS completely on the MB, but that didn't help either.

Is it likely to be a dud card?

Cheers
 
Doesn't the P5K-E only have PCI-E 1?

I believe the 6950's require a PCI-E 2.1, or at least that's the bus they are built for.

It may not be THE cause, but certainly won't help things...
 
I was under the impression that PCI-E cards were backward compatible with older version slots (just they ran under the reduced bus speed that that comes with)?
 
Doesn't the monitor only have a D-Sub (VGA) connector?

I assume you're using a DVI to VGA adapter?

Have you tried both DVI connectors on the graphics card as only one is DVI-I with an analogue output?
 
Correct. Only one of the connectors on the card will fit the adapter. Like I said, the HDMI out doesn't give anything to my TV either.

Also, the PC doesn't try to boot in the background either (no HDD activity). Not sure if it means anything, but I do notice the DVD drive constantly starts spinning up then spinning down when I do turn it on. This continues for ~40 secs
 
If you've been swapping cards I assume you've tried re-seating it and made absolutely sure both power cables a securely fitted?

Other than that it sounds a bit knackered or there is a compatability issue.

Do you have access to another PC to test it in?
 
Yup, at least 12 times now... The other card works perfectly each time. I've tried with only one power connector on the 6950 the fan stays on very loud, when I plug it back it, the fan returns to normal but still no signal! :(
 
Only one of the DVI ports on mine supports VGA passthrough. Before I realised this I stared at a blank screen too. Although I can't remember if my TV got an output automatically when plugging in the HDMI.

The other DVI port on mine doesn't have the correct holes for the pins for the adapter, so presumably the one that does have the holes (the one I'm using) is the one with passthrough. Either way, HDMI still didn't work.
 
Well I sent this back to the seller and he has confirmed to me that he has tested it working at his shop! I simply cannot understand why this didn't work for me....any suggestions?
 
Okay, I got sent another identical card by the supplier and guess what, still get no output whatsoever.

This must be some kind of compatibility issue but I can't find anything to back that up. I've googled and found plenty of other people who have the same MB/CPU/GPU combo as me with no apparent problems.

Should be able to take it round a mates tonight to try it in his which should definitely confirm the card works (although I'm 99% sure it does)

Does anyone have ANY idea why there could be some issue with this card in my setup?
 
Are you using the exact same power connector/s as you have on the 4870?
If you need to use an additional one or an 8 instead of a 6, it could be a dodgy wire?
 
Exact same power connectors (2x 6-pin).

I can literally pull the 6950 out, swap the 2x 6-pins onto the 4870, drop that back in and it works fine every time. As soon as I stick the 6950 in, nothing
 
Yup, fan spins up 100% for half a second, then drops down to normal speed (just as my 4870 does on boot). If I remove one or both of the 6-pins the fan stays constantly on full speed as expected.

The MB has lights which are supposed to come on if the card isn't seated properly, but they don't show at all.
