To be clear from a Dell warranty and policy perspective, a user should not expect our OEM BIOS and OEM tested/validated memory sticks to work without issues using non-tested/non-validated retail memory sticks.
The XPS 8940 is shipped with 3200MHz memory. However, with Intel Core i3/i5 processors, it is limited to 2666MHz. With Intel Core i7/i9 processors, it is limited to 2933MHz.
By any chance do you mean "mini tower"? XE3 comes in mini tower (sometimes generally called desktop because it's not quite full-size) and SFF. The actual DT is a size not used by Dell anymore. Please see images below. Want to make sure because if I hunt, I want to make sure it's the right part. I also noticed XE3 PSU's have been hard to come by.
I don't know how long you had your XE3, but if the PSU is dying, it sounds a bit premature. Since bad batteries and cause on & off, boot, and other seemingly unrelated problems, I'd try replacing the size 2032 CMOS battery with Duracell or Energizer first. Better deals on Amazon than in store.
Yeah, it is a mini tower. The battery was dead, as I was getting that warning at start. I replaced it, but it wasn't a 2032 I just had a 2025, which is slightly smaller. The part number says 8HKG7, with Model L360EGM-00.
I got the Dell last spring, about a year ago. It was a"refurb" model. I check the service tag and it was expired, sadly.
CR2032 battery is cheap. I would not use a different size battery.
pc frequent restarting can be due to psu or ram. If you have another good ddr4 ram test it after removing all old ram.
ask Dell-Chris M whether XE3 board with 6pin-4pin socket is compatible with optiplex 3050 psu. You can get a cheaper 3050 psu. My hunch is these 6 pin 4 pin Dell motherboard all have same pinout, but Dell may not validate it.
2032s are cheap, but I had a 225 on hand and the electrical characteristics are identical. It just won't last as long. It's on ly list to buy, but I haven't yet.
How do I go about asking Dell-Chris M? This is literally my first venture on this forum and I don't want to DM anyone.
Ugh. The sticker is worn and hard to read. I obviously read it wrong. I will boot to BIOS and extract it there, but it will have to wait until I can get home.

are you sure psu is bad?
Y7R0X 500W Chicony = XPS 8940, Optiplex 7080 MT/XE3?

ask Dell-Chris M to verify that Y7R0X is compatible with XE3

No, I'm not sure it's bad. But a PC only turns off for a few reasons.
Bad MB, bad RAM, bad PSU, I'm going cheapest first.
I checked that place out. They want $30 to ship.
The actual PSU is:

But it's $60 with $30 shipping. that's too much of a gamble if it's not bad.

Well, it's not restarting. It's turning off.
2032s are cheap, but I had a 225 on hand and the electrical characteristics are identical. It just won't last as long. It's on ly list to buy, but I haven't yet.

go to https://www.dell.com/community/XPS-Desktops/XPS-8940-part-number-for-500w-power-supply/m-p/7817464#M58181
reply with “@ “ in msg and username participants list pop up, pick his name. I don’t think he would mind a valid user question.

If a GPU card is installed, a 180w PSU from a 3050 very likely won't do the job. Very minimal what it can do.

GPU, but I'd prefer to keep the 360 just in case.
@DELL-Chris M Can you help?

The service tag you provided in private message shows as an Optiplex 3020 MT, not the Optiplex XE3?

Ugh. The sticker is worn and hard to read. I obviously read it wrong. I will boot to BIOS and extract it there, but it will have to wait until I can get home.
Thanks!
