Ati HD3870 Problem

Darksun84 · May 17, 2008, 05:13 PM

Hello,

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

I 've installed it , then i 've turned on the pc and the [COLOR=#000080][COLOR=#000080! important][COLOR=#000080! important]motherboard[/COLOR][/COLOR][/COLOR] 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.
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

If the fan on the card is still running when the system starts and the system boots and doesn't turn off after a few seconds then the card is still getting enough power from the PSU. Yes PCI-E 2.0 is fully backwards compatible, it would work just at PCI-E 1.1 standard speeds.

So it's likely the 3870 is defective, time for an RMA methinks.

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 ?
