Hey guys
I just bought a new video card sapphire hd5850 xtreme 1gb ddr5 but this card refuse to boot with my GA-870-USBL mainboard.
When i turn on the pc with this card the pc wont display anything on the screen and mainboard post 1 long beep and 2 shorts beep which according to the manual this a vga problem.
I have checked all the cables and tried with diferent powersupplies from 350w to 560w seasonic,antec,fsp but no luck.my mainboard is right now working with ati hd3850,but i also have tried with friends ati hd6850,hd6950,nvidia 8600gt all of them worked perfectly in my pc.
I dont why the sapphire 5850 xtreme dont boot with my mainboard because this card works in friends mainboards asus M3A79-T Deluxe,ASUS CROSSHAIR IV EXTREME,Gigabyte P35-DQ6.
I am not sure but i think that the videocard or the mainboard have compatibility problem,i would like to know if this problem can be solved with a new mainboard bios version.
This is my pc specs:
Mainboard: GA-870A-USB3L(rev. 3.1)
M/B Rev: 3.1
BIOS Ver: F3
VGA: SAPPHIRE HD 5850 Xtreme 1GB GDDR5
CPU: AMD phenom II 720 2,8ghz
Memory: Kingston KHX1600C9D3X2K2/4GX DDR3 2x2GB 1600 mhz
Power Supply: 560 seasonic X560 W,antec 430w,fsp 350w
