OptiPlex 7090 Micro Issues with RAM upgrade.

Hey,

in our company we have tried to upgrade the RAM but it doesn't work.. 

From Stock the OptiPlex 7090 Micro have 2x 8GB 3200MHZ DDR4 SODIMM, now we tried to upgrade the RAM to 2x 16GB 3200MHZ DDR4 SODIMM (Corsair Vengeance Series 32 GB (2 x 16 GB) DDR4 SODIMM 3200 MHz SKU CMSX32GX4M2A3200C22)

After RAM-Change an First PC Startup the Status LED blinks 2x Orange & 5x White, what maybe means the Bios Recovery Mode. We also tried it after Bios Update, but no success...

Have anybody an idea or maybe had a similar problem?

Kind regards,

Max
