Good morning everyone. I am no expert but I have basic knowledge of computers hardware.   I have an Opltiplex 7090 Micro, Intel Core i5 with 16GB (2x8GB 1Rx16 DDR4 SODIMM 3200MHz) Per Kingston compatibility page, I purchased 1 dimm KCP432SD8/32 (32gb) and installed it stand alone and the machine light blinks amber and white. and won't turn on. I tried installing it together with one of the 8GB dimms but it's the same. I had to uninstall the 32gb and install the two 8GB in order to work with the computer. Also, the computer works with only one dimm of 8GB.   This are the specs of the 32GB dimm, per Kingston compatibility web page: Part Number: KCP432SD8/32 DDR4 3200MT/s Non-ECC Unbuffered SODIMM CL22 2RX8 1.2V 260-pin 16Gbit [URL] Should I have bought a pair of these 32GB for it to work or is this the wrong memory?   I would appreciate the help.
