HD 3870 PCI e 8 to 16x

Hello,

i have a SAPPHIRE TOXIC HD 3870 512MB GDDR4 PCI-E
But it only runs in x8... not 16x

I have:
MB: MSI 7360 (K9A2 Platinum)
CPU: Phenom 9850 Quad-core.
DDR2 4048Mb 1066Mhz

The graphic card Bios is a version named 010.079.000.001 , Don´t know if i can flash a newer bios or how i can do that (if i´t helps...)

Hope that i can get the speed up to x16 .

thankful for all help!

  1. The MSI K9A2 Platinum motherboard has four PCI-Ex16 slots. Two are rated at x16, two at x8. Make sure your graphics card is installed in a x16 slot.

  2. I have installed it on a "Mazarine" colored PCI-Ex16 slot and i´t is a the right one according to the manual... but still only x8..
  3. Finlay i got x16 :)

    They have wrong color in the manual...
    "the mazarine PCIE x slots (PCI_EX1 / PCI_EX4) support up to PCIE 2.0x16 speed"
    BUT the PCI_1 and PCI_EX4 is BLUE!!!

    Now i have the cart in Blue and it works perfectly :)
  4. Did you try installing the card to the other slots? It wouldn't hurt.
  5. Yeah, that's what I thought... :)
