As the title says, I'm looking to upgrade the memory in my Dell Optiplex 380 desktop.

Applicable memory specs from Crucial:
Memory Type: DDR3 PC3-12800, DDR3 PC3-10600, DDR3 (non-ECC)
Maximum Memory: 8GB
Slots: 2

It's an old work computer the office was going to throw out, so I figured I would use it for tinkering and classwork. Anyway, I took the old RAM out and installed a single stick of Kingston HyperX Blu 4GB stick of RAM (1333, DDR3, non-ECC) but, when installed, I immediately got POST beeps. So, I put the old ram in Slot 1 and the new RAM in slot 2; same result. Same result vice versa. The PC still boots with the old RAM, regardless of the slot, and runs without a hitch, so I know the DIMM slots are good. I've never heard of one bad stick, out of multiple, causing a POST failure (admittedly, I am new to PC hardware troubleshooting) so I wanted to see if it was common.

I appear to be getting error light pattern 1 & 3 which indicates memory modules being detected but there is some configuration or compatibility error (from Dell's service manuals). Based on the RAM specs, I can't think of anything, on my end, that could be causing an issue. I have also reset CMOS using the jumper. Even after that, the system failed POST.

I'm considering sending it back to Amazon, saying it is DOA, but wouldn't want to waste their time and money if it's some other issue. Unfortunately, I don't have a system I can test this module in, at present.

Any feedback is appreciated.
 
Solution
Try a BIOS update on the system. Other than that, the RAM may not be compatible with the motherboard. The OEM systems tend to be a lot pickier with the RAM they work with than the higher end motherboards for gaming systems.

Thanks for the suggestion. I updated the BIOS but, unfortunately, it did not solve the problem. My brother has a system that is not pre-built though, so I will try it there and see if it works. I will post an update afterward. In the meantime, any further suggestions are appreciated.

That was the issue exactly. Thanks for the suggestion. I swapped out one of my brother's 2GB Corsair memory modules for the 4GB Kingston RAM I had and his system recognized it and booted right up. The best part was that he no longer need the 2GB module anymore and it's in the formerly empty slot of my Optiplex 380 right now. Thanks again.
