I have a PE2950 II with 4 x 2GB (HYMP525F72CP4N3-Y5AB-T) installed and purchased 4 x 4GB (HYMP151F72CP4N3-Y5AC-C). Based on what I have seen error message E2011 seems to common when installing UDIMMs however I believe the 4GB sticks I bought are Fully Buffered RDIMMs. I have tried the following configurations and all display the same "E2011 Memory Config Err" on the lcd. I have updated to the latest BIOS 2.7.0
Anyone have any thoughts about what is causing the RAM to not be recognized? Was I wrong about compatibility? Or any suggestions on what RAM would work?
