I have 12 sticks but waiting to see if a team mate can use 4 (16GB), the rest is fair game and will sell the rest of he can't use it.

Used in my Z600s. Will work in the Z800s, T5500s, T7500s and other servers. Note: it's ECC registered DIMMS. Won't work in most workstations. If you can use it, make me an offer. I was thinking $20 for 24GB or $35 for all 48GB. Will ship USPS priority mail.
