Samsung Pro 960 slow speeds

[sonar]

HI.
So I have the latest bios for my motherboard and set the M.2 strap to pcie instead of Sata in the bios. Disabled CSM downloaded windows directly to a usb and installed windows 10 from the bios usb UEFI. Download the new Magician and... Samsung magician performance test shows my 960 pro 500 GB read speed at 1800 and write speed at 1635 when its supposedly rated and tested at 3500 read and 2500 write. The PCIe Gen shows 2 x 4. After that i have 1000000X installed windows again and still shows the same slowly write and read speed. :(:(:(
What am I missing? Is there anything else I can do?
Thanks in advance

just type over your settings of your ram. There on the stick or just google what you have. This is done all the BIOS. Am guessing F7 advanced settings. To the tweaker mode. scroll down and you will the speed of your ram. Change it to XMP setting. Scroll down more and find the option ram timmings. Set those as well. like 16-16-16 30 what ever is on the RAM. Now do not forget to set the Voltage for ram. For that you have scroll down more. Its pretty self explained.

GL HF !

If you haven't already found it, your solution can be found with the Samsung NVME Driver on the Samsung site - located here:

Hello

I didnt read all posts in this thread - just wanted to say that I had the same issue with my Samsung M.2 960 PRO NVME SSD.

Disabling XMP switch on motherboard AND manually in BIOS fixed my speeds.
Another important detail s that (if your SSD is connected directly to motherboard - and not through utility card via. pci-express) You need to enable AHCI in BIOS (not RAID) when installing the nvme driver in your OS.

RAID is a SATA technology as i understand - you shouldnt use it with m.2 drives.

Board: Asus strix X99 gaming.

I am not aware of XMP being any issue for an Nvme drive. And there is no issue with raid either. It just needs to be setup correctly in bios.

Sure, please just read page 4 in the installation guide: http://downloadcenter.samsung.com/content/DR/201710/20171026175901763/Samsung_NVMeDriver_Installatio...

You cannot really argue against it.

I have the same issue except Samsung's Magician says i'm running PCIE 3.0 X1. So i'm only using one lane. I have the Asus Rampage VI Extreme Motherboard with the 960 EVO 1TB NVME SSD installed in the DIMM.2 Slot by the RAM. XMP is enabled. I will try disabling XMP and setting the memory settings manually. I think it's odd that everyone elses EVO is running on PCI 2 x4, whereas mine is 3.0 x1
