Just like on my m8g, the second one is also a fake x16, soldered only x8.
Not sure tough, how much perf % that means, if you just run it x8.

Hello

More a lack of understanding than anything being fake. The product specifications clearly state both the physical and electrical properties of the PCIe slots.

Says 2x x16 on any product spec marketing... and on page 48 in the middle of the book, it says with small font that its only x8.
So yeah... our understandings of "clearly" are a bit different... but of course, you are right.

It's a 16x length slot, one only need look at the pin out on the slot to realise it's only capable of 8x

Hello

Not sure where the small fonts may be. Below is from both the included user manual and product page at ASUS.com. Seems pretty clear to me. No desktop platform with these specifications have ever supported X16 in any slot other than the primary unless explicitly stated otherwise. Any confusion this may create is beyond my comprehension I guess.

I have the 256 version and do not have the issue with the windows driver.

The question was not about what happens when BOTH are populated. The second one cant operate at x16 even when the first one is empty. So they just look like 2x x16, in fact is the second one ONLY x8, whatever happens.
But, i am sure everyone understands where the problem is, so no need to unneccessary overexplain this case.

You're right you shouldn't overcomplicate things. So here we are:

You're an end user, lets work on an assumption that you are not familiar with the lane speeds - typically it's best to assume people aren't.

The slot fits a 16x length card, as does the second one. Inferring the second slot is 8x suggests you are not able to run a 16x length product from it. The over-complication comes from examining the electronic capabilities of the slot, when the manual does specify 8x8x is only possible, and no where specifies that you are able to run 16x 16x.

These things can sometimes get lost in translation, engineers don't write the manuals, and those that are more privy only need look at the pins on the second slot to realise it's not capable of running at full speed (not that there is any performance lose from doing this)

Mind blown. thumb.gif
