DC P3600 Series running at half speed

[cmeit]

Just bought new kit.

Intel DC P3600 Series 800GB SSD PCI-e Adaptor Card Solid State Drive (SSDPEDME800G401)

Asus Xonar DX 7.1 PCI-Express Sound Card

Intel Core i7 5930K

32GB (4x8GB) DDR4 2400MHz Quad Channel Kit

Asus X99-S Intel X99 (Socket 2011) DDR4 ATX Motherboard

Microsoft Windows 8.1 64 Bit

2 x SLI GTX 980 video cards

System works fine. Intel SSD is configured with 8.1 and works will all the software

All bench testing on the components with PassMark shows they are all working fine except for the SSD which is only performing at 800Meg/s

I tried also using Atto bench test and got the same results. The drive is running slower than expected.

All the correct Intel drivers are installed. The Intel test package says it is working OK and link power manager is enabled.

However is read/write benchmarks are less than a 1/3 of what you would expect/ Any ideas guys, is it to do with not enough PCIe lanes being free ??

Any suggestions would be greatly appreciated

Added the new bench test results using suggested settings

Hello EntenErazor,

Could you please attach here the .CSV file that gets created so we can analyze it?

Hey EntRazor,

Have you ever tried HWinfo64.exe ? Its a program that spits out hardware specifications... I'm wondering if your motherboard is down shifting the PCIe Gen speed to Gen 2 or even 1. HWinfo64.exe will provide this information.... If you can be kind enough to run it and provide us the results? If the motherboard negotiates the device at a PCIe Gen2 or even Gen1, This may be something the motherboard may be doing.

Did you over clock the DRAM? I've noticed weird behaviors in PCIe negotiation when the DRAM is over clocked...

Is your sound card UEFI capable or legacy only?

How long should I run it for ? Here is a couple of minutes worth.

HWinfo64 is a quick diagnostic tool... its not a test... so it shouldnt take too long at all... just install.. run, export the results file and share! Word of caution... if you are not really willing to show EVERYTHING about your system do not share the file.... just take a look at the results file yourself.. check to make the the 750 series is negotiated at PCIe gen3
