Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

@jmegas perhaps you can borrow an external CD drive from someone and use it to boot Lenovo's CD update image? Or is the machine so thoroughly hosed that you can't even boot from CD?

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

I didn't know I could do that.  It doesn't even boot into the BIOS, so I think it needs to be flashed somehow.  I would expect that there is a way to do it, but I don't know it.  I called Lenovo tech support and they said that it was "above their pay grade."  As I already had the box, I sent it in.  I'm still quite worried about what to do when I get it back.  I'd like it to work with the parts I have bought, i.e., three additional sticks of Corsiar memory and the Samsung 950 Pro.  It is *supposed* to work with that stuff, but something is certainly wrong.  Nobody seems to know quite what it is.  Most people suspect the memory, but I have rarely had problems with bad memory.  In my 30 years of computing I have only had bad memory one other time.

Don't know if this is related but I had a similar issue with the mSATA drive in a T530.  It turned out that the card was not seated properly in the mSATA slot. Although it looked fine, I removed it, put it back in, screwed it in, rebooted and voila, the drive appeared...

When you get your P50 back, do one thing at a time.  Don't connect any peripherals that you don't need.  Make sure it boots and runs for a while from the factory HDD.  Keep the third party RAM out.  Install the 950 using the tray.  Clone the system or do a clean install from USB.

 

I hope you did not damage the 950 or the motherboard connector when initially handling and inserting the 950 without the tray.

Phil, I sort of thought I did that the first time.  (Not that I won't be more careful the next time.)

 

I was thinking and this will be my *third* attempt at setting up the machine:  when it came from the factory, when I got it back from Lenovo the first time, and this time.  The first time I put the first two sticks of Corsair memory in the bottom, which wasn't a good idea.  Also, I actually believe the NVMe snaps in *better* without the tray.  I think the tray mostly protects it against any sort of electrical contact with other devices in the computer but I will be certain to use it.

 

I agree that I hope nothing is damaged.  I made that comment elsewhere, because they aren't going to test many of the things I really need to know.  I need to know whether all four memory slots are in good repair and whether NVMe Slot 0 is working properly.  I also need to have the latest BIOS.

 

My plan at this point is only to use the Corsair memory under the keyboard.  I don't think I have tried that alone yet.  Then I can add the NVMe *with* the tray.  Finally I can add the final two sticks of memory.  Everytime I have tried all of those items, I have gotten BSOD, so I don't think it will work.  I passed all of the software memory tests I used (PassMark Memtest for 70 minutes and all of the Lenovo hardware tests) so I don't know how exactly to troubleshoot for bad memory.  The specifications on the Samsung SDRAM SO-DIMM Module M471A1G43DB0-CP8 (which ships with the machine) and the Corsair® ValueSelect® DDR4 260-Pin SO-DIMM 2133 (PC4 1700) are the same and they all have timings of 15-15-15.  This is all sort of getting over my head?

jmegas,

Did you ever get your P50 working with the 950 Pro hard drive?

I have an eerily similar problem with a P70 after installing a 950 Pro hard drive and extra RAM. The 950 Pro hard drive is not even recognized by the BIOS or Windows, even though it is physically installed. I know that the RAM is not the problem because I can boot Windows from the 500GB hard drive the computer came with, just not the 950 Pro drive.

Unfortunately I have not gotten my machine to work.  In fact, I have had the machine at home for one functioning day out of the past nearly one month that I have owned it.  The machine is currently being repaired by Lenovo but it is going to take them 2 1/2 weeks to get a single stick of SO-DIMM memory to replace the one which shipped with the machine.  They have also agreed to send me a replacement machine, but I am not confident that one will work with my stuff either.  I have a ticket in with Corsair as well to find out what they recommend.

 

My "case manager" with Lenovo said that I can keep whichever machine I want to, but all I want is a machine that works.  I have never had these sorts of problems with a Lenovo computer before and I have owned close to 10 of them.

 

Did you have good luck with the other brand of memory, and what kind did you use?  I am pleased to hear that most people *have* been able to get Samsung 950 Pros to work in their machines without difficulty, but several others are having problems.

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

I installed 32GB (4x8) of Kingston HyperX 2400Mhz RAM in my machine. I have had no problems with the RAM. Windows is stable when I run it from the 500GB "spinner" hard drive that came with the machine and the BIOS always recognizes the RAM.

My 950 Pro hard drive worked great for 2 days until Windows suddenly froze and crashed, forcing me to power down by holding the power button. The computer has never recognized the 950 Pro drive since and I get a 2100 error every time I boot. Oddly, it usually knows that something is connected to the M.2 port, it seems it just can't figure out that it's a hard drive.

I'm still trying to determine if this is the same BIOS issues others have seen with NVMe drives, or if the 950 Pro Drive just suddenly died on me that one day.

I have talked to Samsung tech support several times.  They seem to think their 950 Pros are pretty much rock solid.  As for the Z170 chipset and the Lenovo P50/P70 BIOS having issues with the Samsung 950 Pro, I think that is a strong possibility.  As I best understand it, Lenovo will not guarantee their equipment to work with anything which they don't ship with the machine even if it is listed as a customer replacable part.  Corsair is now telling me that they don't guarantee four of their modules to work together *unless* they are bought in a kit of four matching modules, even if they are the exact same modules.  I did not know that memory could be that particular.  You are using faster memory that I can use, but I have the Xeon processor.  It is only guaranteed to work with 2133 (PC4 1700) memory--faster memory is *not* supported.

 

It certainly wouldn't hurt to talk to Samsung.  Their tech support is more helpful in my opinion than is Lenovo.  I'm not exactly looking forward to getting my machine back because I could have more nightmares ahead of me.

Just out of curiosity, have you tried moving your 950 from the slot it's in right now (NVMe0) to the other slot (NVMe1) in the M.2 bay?  I'm just interested to learn if perhaps it's the PCIe connector in NVMe0 that somehow went south?

 

And of course, you could request an RMA replacement for your 950 from Samsung (or Amazon, or whoever you bought it from).  Rare as it probably is, there's a chance that it simply "died" when you say Windows suddenly froze and crashed.  The "death" of the 950 might have been the cause of your Windows freeze, or perhaps occurred as a result of the Windows freeze.  Unknown, but trying a second brand new 950 would certainly eliminate your spinning your wheels right now trying to diagnose why your 950 isn't recognized, when in fact it's "dead".

 

Just some thoughts.
