5850 Boot issue

[llewellyn]

Good evening, knowledgeable ladies & gentlemen (and miscellaneous other) of the forum.

My shiny new Saphhire HD5850 turned up today, which is great, but I can't quite seem to get it to work, which is not so great.

Before I RMA it I thought I'd ask you graphics worldly people if you can see if there is anything I've missed before I embarrass myself with returning a working card.

Brief PC specs:
PSU: Corsair TX650W
MB: Asus P5N-E SLI (Bios v1301)
CPU: Intel Core 2 Duo ([email protected])
Mem: 4GB

Problem description:
No POST. No beeps. Power is running through everything (lights on cards & MB light up as expected), all fans kick into life. But no sound and no output.

I still have my old 8800GTS which despite starting to fail (weird artefacts and lines) will allow my system to boot up when it is switched back in.

I have unplugged all extraneous powered devices within the case (such as hard drives, cd drives, extra case fans) just to eliminate them. I have also ensured that both 6pin power plugs are connected to the HD5850 card. The card is in the primary (x16) slot.

Am I missing something obvious here? Is there a known issue with this motherboard and recent graphics cards? etc

Thanks for your time in reading this, hope you can help.


Edit note:
OC have finished testing my card and it seems fine.
This seems to confirm that the Asus p5n-e board has some serious issues with the 5850.

Have you made sure that you have it on x16 slot only, or tried it on dual vga mode with the switcher card?

Wow, that was a quick response.

I can confirm that I have it in the main/primary slot. (Although they are both PCIEX16) according to my MB manual.

I have to admit that I'm not entirely sure what you are referring to with 'the switcher card'.

 

[llewellyn]

PCI-e power connected securely? IS there another PCI-e power connector you could try or a dongle from one of the other power conenctors?

Andy

I've tested to ensure that both connectors are secure. However, I haven't tried splitting off another 6pin from a different power cable and switching them out in turn to rule out a duff cable.

If it will not even post, try reseating You GFX card and make sure its not jammed against anything on the motherboard, even try the other slot

Still no Joy, try Card in another PC

I have tried reseating the card (it's been in and out of the PC a few times now). I'm also definitely using the correct power cables.

I have also tried the different slot

Unfortunately, I don't have another PC I can try the 5850 in (I'm using a laptop for the forum access).

 

[llewellyn]

Morning. Thanks for all the replies guys.

Still no joy

I have tried taking some memory out and I have reseated the pesky card numerous times now (with and without screw holding). Also, power seems fine.

I think I'm left with trying it in someone elses PC. (I'll have to try and persuade a family member to give me access, I hope they still don't have the same motherboard as me )

Has anyone got a HD5850 working with this motherboard? (ASUS P5Ne-SLI) - Assuming that anyone on this board has even got that particular combination.

 

[llewellyn]

Well I've spent another 40 minutes methodically going through each of the tests again just in case I missed something.

The only thing of note is that if I leave the POST long enough (sometimes 30s) it will progress to 1 long beep followed by 3 short beeps, which for my motherboard is: "No video card or bad video RAM" -> Reseat or replace the video card.

So either my motherboard really doesn't like this card or it's a bad card. I'll be testing it in another PC tomorrow, which also has a Asus p5n-e, so it's possible I won't be able to rule out either before RMA'ing it.

How sympathetic are Overclockers to cases like this?

Just a quick bit of thread necromancy to give you an update on this one.
OC have finished testing my card and it seems fine.
This seems to confirm that the Asus p5n-e board has some serious issues with the 5850.

 

[llewellyn]

Does the gfx fan run at 100% on boot?

It does. On both PC's I was able to test. (Both Asus P5N-E). Some people could get it to boot after numerous attempts. Mine wouldn't.

 

[llewellyn]

i have the same board but not a 5800series card, if you look in the forums support on asus site people have this issue, wait one min for it to post you may get a display, then report back.

I did, for much longer than a minute (I used a stopwatch), numerous times.

On a separate note, whilst saving up for a i5 upgrade in a couple of months (i.e. after Christmas most likely), does anyone know if these boards work with the 5850? Or can suggest another Socket 775 that has 4 RAM slots. I don't want to go nuts on cost as I'm not planning on using it long term.
