Wrong speed/latency, wrong size, wrong layout, wrong type … something is wrong with it. Try a single stick in the first slot. I would probably send it back and buy something you can confirm the specs on.
Hi, I have a Dell PowerEdge T310 with Intel Xeon X3440 in it.In theory it is supporting 6 x 4GB RAMI wanted to upgrade my ram, from 8GB to 24GB.It has two 4GB 1333 registered ecc sticks,so I have bought four more sticks with the same specs.When I installed them, I got an error on the servers lcd screen saying:"Memory is configured but not usable"My bios version is the latest possible. I have tried with four 4GB sticks, same error. Any ideas?
