Can you tell us the CPU, memory, and power supply you have installed on this board?

i9 9900k , EVGA SuperNOVA 1000 T2 , g.skill 3200C14D-32GTZR (14-14-14-34)

I got 2 Western Digital 1GB M2's running in Raid-0 and my card still runs at 16x.

thank you all , but i am going with x299 platform i really need the 44 pci-e's

Do you also have this? Nu Audio card
12.81 GB/s Cool  https://www.3dmark.com/compare/pcie/17950/pcie/15196/pcie/15048
This really only shows the difference between GEN 1 2 3 and soon 4.
What is shown in the NVIDIA Control Panel under System Information? X16 or X8?
I am this Close to Getting that Dark, this Close.... I have the Intel Core i9-9900KF Processor and Memory on the way now.
The 9900KF has no Graphics so I wonder if this helps.
Also it is comparing the Bandwidth between the CPU and PCIe Slot not the GPU is a since but what GPU is that? 
The MB is Out of Stock ATM

@ 808sting
x4 from Z390 PCH - 970 Pro 1GB (TOP)
x4 from Z390 PCH - 970 Evo Plus 1GB (BOTTOM) *This is Not an NVMe Drive Correct?
Not using the U.2 Ports so it looks like I am good to go, thanks

Using the following with Z390 Dark & 9900KF:
x16 from CPU - 2080ti KP
x4 from Z390 PCH - 970 Pro 1GB (TOP)
x4 from Z390 PCH - 970 Evo Plus 1GB (BOTTOM)
 
Cannot use any slot or U.2    
(per page 26-27 from manual)
 
We'll see what happens with Zen 2 or Intel's HEDT follow-up.  9900x or 9920x doesn't look that good anymore.

You also have PCIe Lanes from the PCH
The EVGA Z390 DARK Motherboard with the Intel ® Z390 and PCH Chipset.
Support Manual for EVGA Z390 Dark (131-CS-E399) Page 27

USB 2.0 Ports:
4x from Intel
® Z390 PCH – 4x internal via 2 FP headers



PCI Express Expansion Slots:

*LANES PER SLOT CAN VARY BASED ON DEVICES INSTALLED. PLEASE SEE PAGE 27 FOR LANE BREAKDOWN.
 
2. Intel ® Z390 PCH (Southbridge)
The Platform Controller Hub (PCH) handles the role that was previously held by the South Bridge. The PCH allocates bandwidth to smaller PCIe slots, M.2, USB, audio, etc. In simplified terms, the PCH works as a hub for peripherals that are less bandwidth-intensive.
 
9. Intel ® SATA 6Gbit/s Ports
The Intel ® Z390 PCH has a 6-port SATA 3/6 Gbit/s controller (See Page 48 for specifics on the connectors). This controller is backwards compatible with SATA and SATA II devices, and supports SSDs, HDDs and various types of optical devices (CDROM, DVDROM, BD-ROM, etc). The controller also supports NCQ, TRIM, hot swap capability (provided the proper HDD/SSD bays/racks are installed), and RAID levels 0/1/5/10.
 
16. PCIe Slot x4*
PCIe x4 slot PE3 uses up to 4 Gen 3 lanes from the PCH. This slot is typically used for sound cards, WiFi, USB, LAN or other peripheral cards.
Using this slot will have no effect on the bandwidth or throughput of the x16 slots used for SLI because this slot uses only PCH bandwidth.
 
PCIe Slot Breakdown
PCIe Lane Distribution (All Socket 1151 processors are 16 lanes.)
PE1 – x16 (Gen3, x16 lanes from CPU, x8 shared with PE2)
PE2 – x8 (Gen3, x8 lanes from CPU, x4 shared with PE4) Cannot Be Used with 2 GPUs
PE3 – x4 (Gen3, x4 lanes from PCH)
PE4 – x4 (Gen3, x4 lanes from CPU, shares 4 of PE2’s 8 lanes)
 
M.2 / U.2 Slot Breakdown
M.2 Lane Distribution
M.2 Key-M (110mm, Top, PM1) – x4 from Z390 PCH
M.2 Enable/Disable is set within the BIOS
This M.2 Key-M slot shares lanes with the U.2 port. Installing an M.2 device will disable U.2 port PU1.
M.2 Key-M (110mm, Bottom, PM2) – x4 from Z390 PCH
M.2 Enable/Disable is set within the BIOS
This M.2 Key-M slot shares lanes with PE3. Installing an M.2 device will disable PCIe slot PE3.
M.2 Key-E (32mm) – x1 from Z390 PCH
M.2 Enable/Disable is set within the BIOS
 
U.2 Lane Distribution
U.2 (PU1) – x4 from Z390 PCH
U.2 Enable/Disable is set within the BIOS
This U.2 port shares lanes with the M.2 Key-M slot PM1. Installing a U.2 device will disable PM1.
 
Hope this Helps a Little.
Note that the X299 Chipset has No PCH PCIe Lane Support.
 
Internal RAID Controller Beyond this Thread
This section introduces RAID, RAID levels, and the basics of the controller integrated into the PCH.

Abe_T82, 
 
If you want to run the graphics card at its full 16X speed you cannot have any other PCIe device installed not even a 1X card like the Nu Audio because that is taking 1 lane out of the CPU.
 
You have 3 options:
 
1. use the RTX 2080 Ti KP on its own to get the full 16X speed
 
2. RTX 2080 ti KP (8X) + dual M.2 SSD (4x + 4X = 8 lanes) = both combined would use all 16 lanes
 
3. RTX 2080 Ti KP (8x) + Nu Audio card (1X) and would basically leave 7 lanes available.
 
hope this helps.

so there is actually a way to have 2 m.2 at full speed with gpu at x16 !!
so why is that guy told me there is no way? i said in the very beginning that i am a NOOB , i didnt build a pc for ages 
if i understand what the manual says then why would i ask , i hardly understand that pcie thing now i need to study the PCH

Correct, One GPU @ x16 or Two GPUs @ x8 Each
Maybe because you added the Nu Audio PCIe Device. "using any other PCIe device in the system will cause the card to operate at 8X" and oversight & Overworked.
Remember using 2 M.2 *110 this disables PE3 that is also controlled by the PCH Chipset.
If you used only the PE3 for the NU Audio Card then you cannot use the two M.2 110 Ports.
From above "This M.2 Key-M slot shares lanes with PE3. Installing an M.2 device will disable PCIe slot PE3."
 
You need x8 on each Graphics Card to run SLI.
 
PE1 – x16(Gen3, x16 CPU With a Card in PE4 this Drops to x8
PE2 – x8 (Gen3, x8  CPU (This is why you cannot use this PCIe Slot with 2 GPUs or 1 GPU and the NU Audio Card in Slot PE4)
PE3 – x4 (Gen3, x4 PCH
PE4 – x4 (Gen3, x4 CPU Has 4 and uses 4 from PE2 Making it x8
