Installing memory in PowerEdge T320

Hi,

I have a Dell PowerEdge T320 server with 8GB RAM, and acquired recently another 8GB, but the server is not accepting the new memory. I've tried connecting it in different slot combinations, with no success. Any suggestions?

The original memory is a Kingston KTD-PE316S8/4G (Reg.ECC, DDR3, 1066MHz, 1Rx8). The new memory is a Transcend TS512MKR72V6NL (Reg.ECC, DDR3, 1600MHz, 2Rx8)

If I only install the old memory or only the new one, they work fine, indicating 8GB, so they are all working. If I put them all together, the BIOS indicates a write error on the higher numbered channels, and recognizes only 8GB. Could someone help me understand what is happening?

Thanks,

Roberto
