Yes U2 that appear correct 800 per channel 1600 in dual channel mode.

It appears on this Inspiron 13 7386. I do have 2 8GB sticks the problem for me is that Hwinfo64 nor cupid can read them. I was about to pull this <Profanity removed> apart When I check in with support and they explain that the RAM on this model they are soldered on to the motherboard

I was happy to find 1 16gb stick in my laptop.  I bought a second and now I have 32gb for only an extra $60.  My laptop is noticeably faster for what I do (Game Development, most of my time is in Visual Studio and Unity).

 

Next, I'll replace the SSD, the random reads/writes are not great.  But it is less noticeable with a larger read/write memory cache.

I am glad Dell doesn't solder their parts in or make it difficult to replace things.  I quite like this laptop.

Glad to hear you got it all sorted out. I really like Samsung SSD M.2 and SATA ones are all the best and fastest available. I do not use Magician or rapid mode although in your case it might work out. What  Rapid Mode is a RAM Disk it works great with small Transfers, on large volume transfers its really no help.

Hi Clint - I'm not sure if the forum notifies you of new responses to old topics so I hope you see this. I have a 7786 17inch and it will not accept a 2.5" SSD. 

 

The manual states that it accepts:

One 2.5-inch hard drive SATA AHCI 6 Gbps Up to 2 TB

and

M.2 2280/2230 solid-state drive PCIe NVMe up to 32 Gbps Up to 512 GB

 

Mine has the factory 256GB M2 NVMe and I wanted to add a 1TB SSD to the SATA slot. However, it will not work. I sent it back to Dell thinking it was a BIOS issue because it wouldn't even allow it to boot and after 15 days all they did was re-install the OS. 

I just wasted about an hour talking to Dell support about this and they are claiming that the SATA port only accepts mechanical HDDs, not an SSD.


So, your signature says you have a 512GB SSD. Is that still true? I guess that means you can confirm that it accepts a 512 but it seems to not accept a 1TB. 

Thanks!

There is no difference between a 2.5 hard drive and a 2.5 SSD they are exactly the same physical size and a SATA 3 connection. If you couldn't get it to boot you should have cloned from your current OS SSD to the new one. most likely your system is running on RAID driver so if you want to clean install you'll need to install the IRST driver first

https://www.dell.com/support/article/us/en/04/sln297920/reset-or-reinstall-windows-10-on-your-dell-c...

you say you have m.2 2280 slot NVME that should work with up to 2 TB for sure 1 TB  your model just hasn't been tested with any larger SSD,  you may only have 2 lanes open the newer m.2 SSD are 4 lane is this is true you'll only get half speed. Look in your Service manual you may have a 256GB 2230 card and if that is the case you'll need the 2280 adapter. on mine the bracket just turned around and mounted for the 2280 card. My 512gb is a 2230 card my system has both a 2280 and 2230 slot so I just moved it to the 2230 slot and installed my 1 TB Samsung 970 Evo and cloned the 512 to the 1TB  then formated the 512GB

@Clintlgm(or anybody else): I just want to clarify what you just said as there's a lot of different info in this thread and I don't want to buy a bunch of stuff that may not work.

Regarding RAM, M.2, SATA SSD, and NVMe, the manual lists the following capacities:

* RAM: 2x DDR4 slots, 16 GB each

* SATA: One 2.5-inch hard drive | SATA AHCI | 6 Gbps | Up to 2 TB

* NVMe: M.2 2280/2230 solid-state drive | PCIe NVMe | up to 32 Gbps | Up to 512 GB

Which of these are actually the maximum capacities? (It sounds like you are saying the NVMe capacity is not really limited to 512 GB. Can you confirm that? And are the other capacities true?)

What you seeing in your manual is all that was tested at printing time. 2.5 SATA SSD are limited to 4TB this is determined by what will fit. Samsung has 4TB SATA 2.5 SSD at 7mm thick your maximum thickness is 9mm.

M.2 NVME PCIe 4x 2280 max is 2TB The only limitation should be what will fit. 128 through 2TB all have the same dimensions At least Samsung I don't have any experience with other brands.

2X16 +32 that's a lot of RAM for a notebook This could be controlled by your BIOS or CPU or both.

If I'm mistaken with any of this please correct my errors, anyone

@cpeggo 

Install CPU-z:

Go to "SPD" 

There you will find the "Slot" numbers and what is installed.

@U2CAMEB4METhanks! I will try that to check out the memory speed.

To follow up on this: the manual has sections called Storage and Intel Optane Memory:

 

Storage

One 2.5-inch hard drive | SATA AHCI | 6 Gbps | Up to 2 TB

M.2 2280/2230 solid-state drive | PCIe NVMe | up to 32 Gbps | Up to 512 GB

 

Intel Optane Memory

Intel Optane memory functions only as a storage accelerator. It neither replaces nor adds to the memory (RAM) installed on your computer.

Interface: PCIe 3.0 x2 NVMe

Capacity: Up to 32 GB

 

But I can only find one M.2/PCIe connector on the motherboard, containing the factory-installed Intel Optane memory:

 

motherboard.jpeg

 

NVMe.jpeg

 

1. Am I correct that there's only a single M.2 connector on my motherboard? If so, then it seems I can either use that slot for the "storage accelerator" (cache?), or as an NVMe hard drive, but not both. (The manual is very misleading about that.) Is that right, or did I miss another slot somewhere?

2. The manual says that the capacity of the M.2 slot is 512 GB as an SSD, but only 32 GB as the "storage accelerator". That's a little confusing if it's the same slot, but I guess that still makes sense. But what's the actual capacity of this M.2 slot as used as an SSD? (The Crucial.com link includes NVMe SSDs up to 2 TB -- you're confident those will work?)
