Are you sure you don't have a Precision 3620 instead of an Optiplex?

Duplicate posts typically delay answers, by the way.

Oh yes, you're right. It is a Precision (Midi) Tower 3620.

I'm sorry.

@Orcrone,

You are correct. Just keep in mind that the 2242 that goes in the WWAN slot is a cache-only drive.

Yes, you can replaced the current M.2 with a larger M.2 if you don't want to install a 2.5 inch drive.

@Aliexdsg,

Sandisk x400 = B & M keyed M.2 SATA

Samsung 960 Evo 256Gb = M key M.2 NVME ( PCIE )

I took a look at the replacement parts we have for the 7460 and all I see is M.2 SATA drives. My assumption is that the 7460 only supports M.2 SATA and it's port not forwards compatible with M.2 NVME drives.

I don't think the 960 evo will work on the 7460.

@Critical1,

I was told by engineering that the 2.5 inch bay drive connector is wired as SATA and NVME. It's wired as 2X.

@Brueck,

Send me a friend request, including your service tag and email address. We can work something out.

Hello, Justin, hi Darr.Darr

Yesterday I received the announced new NVMe. It's not a Toshiba as they said on Wednesday, its a Samsung SM961. But even this was not recognized by the BIOS.

Since now the whole system didn't start anymore, a Dell service technician comes in today and replaces the motherboard again. Allegedly, a refurbished board was used last Wednesday and that was might be probably not quite in order. Now a completely new motherboard should be installed today.

The behavior of the pc is at time as follows:

When I plug in the power cable, the fan moves very shortly. Then the Power Button lights orange. Static, not flashing. I suppose that means something like "PSU is working but failed to fetch code."

As soon as I get new information, I'll tell.

So far, thank you for your help.

Hi Justin,

I have a Precision 3520. It goes with 68 Whr and 2TB HDD. I would like to update to M2.0 SSD. I search google and I found your answers here. I would like to ask for detail.

Based on your information:

================================

Precision 3520

Maximum internal dives supported: 2

Drive configurations supported: (1x M.2) (1x 2.5inch SATA) (1x M.2 cache drive and 1x 2.5 inch drive )

PCIE Lanes:

M.2 slot supports 4X

2.5 Inch bay is wired as SATA

Parts needed to upgrade from 2.5 inch drive to M.2 drive:

1x 2FFR0 end bracket

1x X3DN4 -Thermal plate

1x 4270E - End screw

================================

My question is will compo 1x M.2 cache drive and 1x 2.5 inch drive returns performance as a 1x M.2?

If not I want to upgrade to M.2.

Do I really need to upgrade to 92 Whr like the manual suggest? or I can use my current battery? I don't want my laptop heavier.

Where can I get the part to upgrade to M.2 drive? Can you provide me a link for it?

Thanks

Thang Nguyen

I tried for 2 days on the phone with Dell support and sales trying to get 92Whr battery. They are not available. A senior tech finally told me the 68Whr battery should work fine as the M.2 will use less power than the 2.5 drive. Samsung M.2 950Pro works great in my 5580. The manual is incorrect.

Hi Justin

I just ordered the XPS 13 9360 Developer Edition. I ordered it with the 128GB SSD as my intention is to immediately swap it for a 1TB SSD.

The info at the top of this page states that the XPS 13 9360 M.2 slot supports up to 4X lanes. My intention is to install a Samsung 960 Evo SSD but I've ready conflicting reports on other forums stating that the 9360 only runs at 2X lanes and so the full speed potential of the drive cannot be achieved. Others say it's due to thermal throttling that the full SSD speeds are not being achieved.

Can you please confirm that the M.2 slot does in fact fully support 4X lanes and is compatible with NVMe SSDs using 4 lanes. If the speed is being choked by the M.2 slot there is no need to be spending a premium for a super high speed SSD if the speed isn't achievable.

Is anyone else here using the Samsung 960 Evo in the XPS13 9360 and achieving near full read/write speeds?

Thanks.

@Airthang,

Thank you for considering the Precision 3520.

The 2.5 + cache drive set-up is meant to improve performance. However, it does not provide the same level of performance that a single M.2 drive would.

As Trogspeed mentioned, our user's guide is wrong about the battery and I'm having that corrected. You can run either size of battery along with an M.2 drive. If you run a 2.5 SSD drive, only then do you have to run a 4 cell battery.

Send me a PM with your service tag and I'll see if we can get you a quote for the parts.

@H0llym0lly,

My data come from Dell engineering. I will do more due diligence however and get back with you.

Hi Justin

Any news back on whether the XPS 13 M.2 slot is fully 4 lane capable for NVMe SSDs?

Thanks

Hello Justin-C

Please excuse me for late reporting.. I am currently on vacation and rarely have access to the Internet.

On Monday 8 days ago I got a new motherboard from dell support. This was working with the new NVMe PM951, but not the previous Toshiba NVM. But as this doesn't brother me, I agreed with this constellation.

Last Monday, so. 3 days ago, the computer did not start again. So I called support again. Now I'm supposed to get another motherboard. The fourth one, now!

The reason why I'm writing this now is not to scold the German Dell support. I have rather made an observation on which I do not see a direct connection. I have connected two Dell U2412M units to the Precision 3620 by DP cable. If I disconnect one of them, I can start the computer. Mostly at least, but not always. Unfortunately.

Is it possible that two monitors are too much for the PSU? We have many of the U2412M, but no matter which one I use, the computer doesn't want to use 2 monitors.

Du you having any idea with that information?

Thanks for your help
