already checked it. 4 x @ 10Mb so 4 x PCIe 3.0

Sequential read is 1557MB i have seen it over 1600 on the first run so repeated runs it gets slower. So im suspecting heat.

You cannot be serious. RAPID mode is a cache on your RAM, when you run the benchmark, you are benching the cache on the RAM, not the SSD.
You drive is not running at 6000+ MB/s. Also RAPID only helps with programs that have high Queue Depth Usage. Regular usage, Rapid mode doesn't do anything.
The 950 Pro results, that is actually how fast the SSD is running, so it is better than the 840 EVO.
Also Redstorm, check to see if your Lenovo's M.2 slot is x2 lanes or x4, cuz you needs x4 to get the full performance of the drive.

You install the Samsung driver?
First sentence under performance. Using the Samsung driver.
Sorry, i read fast and sometimes skip things to get the gist.
Did you clean install the drive or clone?

What does "4 x @ 10Mb" mean? I'm pretty sure the limiting factor is the laptop itself because the Lenovo Carbon X1 (2015) with SM951-AHCI wouldn't go over 1500MB/s either, but when I put it inside my desktop I was able to pull ~2200MB/s.
If you want to rule out any potential heat issues, change the number of runs in CDM to 1 (default is 5). That way it will read/write less and thus it should not have time to heat up as much.
In reality after the overhead each lane is only delivering ~8Mbps.
Without a good heatsink, the 950 Pro and SM951 will overheat under extended stress causing thermal down-throttling to kick in. Our stress test was the Blackmagic Disk Speed Test cycling over and over. After 10 minutes, the SM951 on a M.2 board with NO heatsink reached as high as 180F/82C -- or way beyond Samsung's maximum recommended temperature of 158F/70C. With the Angelbird Wings PX1, even after 20 minutes of stress, the temperature never rose above 122F/50C. No other manufacturer or home-grown heatsink we've tested achieves that heat dissipation effectiveness.
The transfer speeds attainable by the Samsung 950 Pro and SM951 depends on bandwidth of the PCIe slot in which the Wings PX1 M.2 adapter (or any other M.2 adapter) is installed. As expected, the large sequential READ speeds were 'through the roof' when we benchmarked using the x8 PCIe 3.0 slot of the Hackintosh. The inability to attain those speeds is frustrating for Mac Pro tower owners with x4 PCIe 2.0 slots and Mac owners using Thunderbolt2-to-x4-PCIe-2.0 expanders. Thunderbolt 3 can't arrive fast enough.
Bare Feats tested the new Angelbird Wings PX1 M.2 adapter with the Samsung 950-series chips:

Regarding performance: (note that this was tested for OS X usage)
Something to consider if you're concerned about heat-based throttling.

Looking to build a new PC in a couple weeks and I'm planning to use a 950 Pro installed on a Asus X99-Pro/USB 3.1 motherboard and would like to know if there's a concise how-to for installing Win10 on it and to make sure UEFI is available.

Asus advised me to set CSM to Auto and let the mobo figure out what to do. This resolved an issue I had with my GPU not working if I did a UEFI boot.
What's odd is that most other sources see to say to disable CSM.

The optimal UEFI settings for a modern platform would be:What's odd is that most other sources see to say to disable CSM.
I just did some reading on that card and some people can get it to work with secure boot and CSM disabled and some people can't. Seems to vary depending on the manufacturer of the card. In one thread I read EVGA advised a user to "just run legacy mode". aka have CSM enabled. You're probably best doing some digging on your actual card or maybe email the manufacturer to ask if it supports secure boot. But if you have already tried it and it didn't work then it probably doesn't. Just make sure your mobo UEFI is up to date and if there has been an updated UEFI for the dGPU card.My 780 has a UEFI bios, Is there a difference between this and fully enabled?
