OMEN 880-160se 1080 TI Graphics Card Issue PCIe is x8 not x16????

OMEN by HP Desktop PC - 880-160se 2TB61AV
Microsoft Windows 10 (64-bit)

Just recieved my new OMEN 880-160se Intel i7 8th gen on 2/16/18.   It has an NVIDIA GTX  1080 TI card but the PCIe is x8 not x16 speed.  It also has 256gb m.2 NVME drive that shares the available PCIe bandwidth. There s/b enough PCIe bandwidth for both. This sounds like a rushed out (one size fits all BIOS) that allows for dual GPU's where both cards would have to be at x8 PCIe link width.

 

How can I get this single GPU to opperate in x16 bandwidth?  I'm on original BIOS F.13 Rev.A.  Is there a BIOS update fix/eta?  Should I return this desktop?

Hi

 

Have you seen this thread?

 

Same issue and system.

 

We are at a loss as to why this situation exists as the Z370 chipset provides more than enough PCIe lanes to meet graphics and other I/O demands.

 

The OP in the referenced thread has contacted the HP Omen Team for support.

Hello,

 

Welcome to the forum.

 

Do you have anything connected to PCIe x1 it will take 1 of those 16 lanes, but because way it works main slot wont go x15 but will default to x8 (PCIe lanes which i saw so far are x16, x8, x4, x1) speed. So if you got something in that slot  it may be reason. However x8 won't affect the performance of your card anyway.

Regards,
Matt

Have you seen this thread?  The MB has both PCIe x16 slots only physically wired for x8!!!  HP deceived it's customers!!!

I wish I had found it earlier.

 

I am not-happy owner of HP Omen 880-500ng (880-500 ng).

 

I have realized that my RTX 2080 Ti is working at PCIE x8 speed only! Shame on you HP.

 

I need fast data transfer for my scientific computations project. Because this transfer bottleneck my "old" PC with 1080 Ti runs faster than top/hi-end gaming PC from HP (I had about 10GB/s transfer in old PC and by buying the new one I wanted to even increase this rate)! This is unbelievable! Seems that over one year passed since people discovered this problem and HP did nothing.

 

There is no single information about it on official technical description in HP store about it. There is just stated that it has "2 PCIe x16". And I guess nobody checks detailed information because this is unseen on market to have such a motherboard. I have just checked plenty (even cheapest!) motherboards from different vendors and every single MB has first PCI x16 working with 16 CPU lanes.

 

No! Sorry for my mistake, not every motherboard - HP doesn't!
