You might look at part numbers P9RN2 or PK4TR. These are DIMMs that run at the speed and capacity you're looking for, and the server itself can support a maximum of up to 192GB of memory when using supported 32GB DIMMs. 
Want to put 32gb in a T320. This would replace any RAM in there already. I've had issues with T310s being picky about the RAM that they like, so I wanted to ask if anyone had had issues with T320 RAM. For 32gb, Can I get four 8GB sticks, 2rx4 pc3 10600R? Thanks!
