AtiHD3870 Issue

Darksun84 · 19th May 2008, 04:38 AM

I've recently bought a Sapphire HD 3870 512MB GDDR4.

I 've installed it , then i 've turned on the pc and the motherboard makes 4 BIP , a long beep followed by three short bep ( the "signal" for video card not found ?), the system continues to work, but nothing in the monitor appears.

I 've an ASUS M2N as motherboard and as PSU a Tagan TG700-U33 .

I've tried another graphic card and it's work correctly.

Then :
1) ASUS M2N doesn't recognize the pciexpress 2.0 even if i've read that
pcie 2.0 is backward compatibile
2) The PSU doesn't give much power to the card(I don't think it's a good PSU).
3)The hd3870 is broken

In very rare case , the hd3870 works , but while booting , the fan of the graphic card stops, so i 've removed and re-inserrted the pciexpress alimentation plug and the fans restart.

Best regards,

Pietro

PS: sorry for my english

Your PSU is more than enough and better than my Corsair actually lol. Even running Crossfire more than enough there.

PCI Express 2.0 is backwards compatible. I think you mentioned you PCI-E power connection was connected properly. Make sure your default video is PEG in BIOS.

Other than that sounds like you may have a defective card

If the motherboard worked before you installed the GPU, then RMA the GPU, if a new one dosen't work then you either got two defectives in a row or more likely, either your psu's +12 volt rails are going bad or your motherboard doesn't support the HD3870 for some reason.

Your current PSU isn't the issue you should be able to run 2 hd3870x2 with it or even 2 8800gtx

I am thinking you have a bad card .. have you tried this in another machine ?

That error beep = motherboard not able to detect any graphics card.

Darksun84 · 19th May 2008, 09:20 AM

This afternoon i 'll try the card in another pc.

Hello
I've tried the video card on a another motherboard, an Asus P5K , and it's working fine!!

So i think it was a problem of the Asus M2N , i wonder if i can replace it with an Asus M3A ?
