Windows 10: Asus X99-Deluxe/U3.1 + Samsung 950 Pro (250GB) M.2 Speed Issues?

Hello,

I have the following:

- Asus X99-Deluxe/U3.1
- Intel i7-5820K Extreme Hex Core CPU Processor (3.30GHz, 15MB Cache, 28 Lanes)
- Samsung 950 PRO NVMe M.2 256 GB Solid State Drive
- Asus STRIX GTX970-DC2OC-4GD5 NVIDIA GeForce GTX 970 Graphics Card

I have only the Asus Graphics Card in the PCIEX16_1 which is running at PCI-E 3.0 16x as expected. I have removed the USB3.1 card that comes with this motherboard for testing purposes so I literally only have the Graphics card installed.

The board has an onBoard M.2 x4 Rev 3 connector which the Samsung 950 PRO is installed into.

I believe this connector should allow 32Gb/sec bandwidth (since it uses PCI-E 3.0 x 4) - please note there is also an optional card where you can add the M.2 (or a second M.2) into a PCI Express slot - I'm NOT using this card, just the onBoard connector.

Samsung Magician says the following:
- Controller: Samsung NVMe Controller (Driver Ver: 1.4.17)
- PCIe Slot: PCI Express Root Port 1 - 2F03
> Link Speed Cur: 4Gbps, Max: 8Gbps
> Link Width Cur: x4, Max: x4
> Bandwidth Cur: 16Gbps, Max: 32Gbps

The performance data also suggests this - the read speed should be a lot higher but seems to be reduced, whereas write speed which is a lower number is over the actual "Upto Speed".

It appears as if my SSD is running at PCI-E 2.0 speeds? The bandwidth is being throttled. Any ideas how I make it go to 32Gbps instead of 16Gbps?

Thanks in advance!

Thanks for your response Gerry. My computer is a custom build from Asus X99-Deluxe U3.1 with a 5820k processor and the most up to date Bios which is 3301 for Windows 10 x64. Here is the link to the requested information you asked for Upgrade Errors items 3-13-2017.
Hope this helps

 

{SOLVED} Build 11102/11099/14251/14257/14271/14295 Failing to install, ERROR CODE 0x8024200D and 0xC1900107 and 0xC190020E , 0x800704CF

i have two 300GB hard drives and a 250gb one

but my windows partition is 60.78gb

no idea why it is so big when nothing is installed on it

Yeah im looking to upgrade to an M.2 SSD , maybe the samsung NVME M.2 the samsung 950 pro i think, the really fast one thats 3GB/S transfer speeds,, would be a nice upgrade from my 15yr old drives

Thats all they do man

copy and paste

you guys helped me soomuch

but yeah i got no idea what it done

 

Believe it or not, I've just stumbled across the solution.

I am using high FSB Corsair Dominator sticks and had them using an XMP (Extreme Memory Profile) - essentially my memory was overclocked.

I thought I'd try running in "normal" mode ie. stock settings and when I checked, the Samsung Magician is now showing as 32Gbps!!

The motherboard must sacrifice something to run the Memory at the higher clock speed which means it can't run the M.2 at PCI-E 3 and has to drop it to PCI-E 2.

Worth baring in mind for anyone else trying to achieve these elusive 32Gbps speeds

Thanks for posting your fix to your problem........just might help others......

 

Hope so.... might save them their Sunday afternoon that I've spent trying to figure this one out! *Smile
