KIND OF SOLVED Sapphire Eyefinity 6 HD 5870 use 8 lanes?

Good evening everyone. I have a Hacintosh with a Sapphire Eyefinity 6 5870 card installed, running Lion. In the system report, this is what shows up.

Any idea why the graphics card is listed as using only 8 lanes? My geekbench overall score runs about 12000.

My motherboard is a Gigabyte P67A-UD4-B3 with a 2600K i7 processor.

Also, why does my machine show up as an Early 2008 Mac Pro?

Thanks in advance for any information.


Well thanks to a previous poster, I was able to get my video card showing up as using 16 lanes.

Just follow the instructions from a previous post below.

"My pci card was linking at 8x instead of 16x in System Profiler. In Graphic/Displays PCIe Lane Width it kept saying 8x instead of 16x (this also verifiable in windows using GPUz)

The fix was simple. Up the BCLK to 1003.

It seams that the default BCLK 1000 leaves it at 98.98 Real BCLK. For some reason the gfx card requires for the real to be at over 100 to connect at 16x. The way to do this is to bump the BCLK to 1003 and this effectively gives us 100.1 real.

This was using a P67a-UD5 with a XFX HD 5770."

My Hackintosh also shows as an Early 2008 Mac Pro. I saw somewhere where you change your serial number so that it would reflect more closely what it actually is.

If anyone knows how to change the serial number it would be helpful.
(I'm thinking that this issue may have something to do with my not being able to login to the app store too)
