HP was trying to pull a fast one and think gamers would not look for something like this. Sadly mistaken and its false avertising. I believe they made this by design BUT was not honest with their customers.

 

The only way HP can fix this is with a updated motherboard revision.

Hi,

 

I looked at Z370 mobos made by couple of major manufacturers and not one had PCIe x16 slots hard wired for x8.

Hi

 

I checked my Asus (Z370) Maximus X Hero MB.

 

It has one x16/x8_ 1 slot, one x8 slot, and one x4  slot. Again, my 1080 is running at x16 in the x16/x8_1 slot closest to the processor socket.

 

I could see where the open x8 slot only had internal contacts viewable in one half of the slot.

 

Just checked an unused H170 MB with two x16 slots.

 

The top slot (x16) has contacts along the entire slot. Curiously, the second x16 slot (etched on the MB as an x16 slot) has contacts on one half of the slot.

I'd be interested to know if this is the case on Alienware systems too, they probably use a custom MB.  If HP is trying to compete with them, they can't be making these mistakes on their gaming machines.

Do we think that manufacturing could have mistakenly installed PCIe x16 socket frames only supporting  x8?

Hi Big_Dave

 

A mistake or a design decision??

 

The H170 I looked at has two x16 slots which were both etched on the MB as x16.

 

This board supports Crossfire.

 

Yet the second x16 slot was clearly only going to run at x8 with either a single graphics card installed in this slot or in Crossfire with two graphics cards.

 

x8 in the second slot is industry standard. I just thought it was misleading to see the second slot marked at x16 when it would never run at x16.

 

The second slot on the Maximus X Hero was clearly marked as an x8 slot.

Depends on the flexibility of the BIOS if the primary x16 (closest to the CPU) slot is unoccupied and then the secondary x16 slot is occupied as the primary.  I have seen this situation on at least one mobo.

Hi Big_Dave

 

That makes sense.

 

Asus MBs usually specify the first slot only for x16.

 

Then both slots run at x8 if a second graphics card (Crossfire or SLI) is installed in the second slot.

 

The second slot on the Maximus X Hero and the H170 MBs I looked at were clearly missing all of the contacts required to run at x16.

Hi

 

Very interesting and educational. :generic:

 

I have never really looked this deeply into this subject until this thread!

Alienware is doing the same thing with their newest R7 gaming desktops. Believe I mentioned it earlier in this thread as well.
