All Replies Posted by DELL-Daniel My on 13 Feb 2013 19:02 Hello Adrian Are you able to enter the system BIOS or BMC/ESM via F2 or CTL E? I would recommend clearing NVRAM via jumper on the system board. Power down, remove power cables, move NVRAM jumper to CLR, and then power on the server dell poweredge memory configuration not optimal for a few minutes. Use the same steps to move the jumper back over. If the issue persists then you will want to start taking the system to minimum to POST. These are the items required to POST: System boardProcessor (with heatsink) in socket 1One stick of memory in slot 11 power supplyControl panel (to turn on system)SideplaneBoth PCI risers in matching configuration Thanks Daniel MysingerGet Support on Twitter @DellCaresPro Download the Dell Quick Resource Locator app today to access PowerEdge support content on your mobile device!

Posted by adrian_edgar on 14 Feb 2013 3:33 Thanks Daniel I can press F2 as it first starts and it says entering setup but it never gets there. Same for F11. I'll try your solution today.

Dell Warning: The current dell poweredge r610 memory configuration memory configuration is not optimal. 12 This entry was posted in Reference Technology and tagged 2950 Dell memory not optimal PowerEdge RAM warning on December 23, 2009 by Steve Jenkins (updated 1850 days ago) In http://en.community.dell.com/support-forums/servers/f/956/t/19491622 a cabinet in a top secret location somewhere in the Pacific Northwest, I've got two Dell PowerEdge 2950s, each with four 2GB DIMMs installed. I purchased four additional 4GB DIMMs to upgrade the memory in both to a total of 16GB, and installed them in the servers last night, so that each server’s DIMM slots were set up as follows: 1:2GB 2:2GB 3:2GB 4:2GB 5:4GB 6:4GB 7:[empty] 8:[empty] I booted the upgraded http://www.stevejenkins.com/blog/2009/12/dell-warning-the-current-memory-configuration-is-not-optimal/ systems, and was greeted with the following warning: Warning: The current memory configuration is not optimal. Dell recommends a population of 2, 4, or 8 DIMMs. DIMMs should be populated sequentially starting in slot 1. The online manual explains the warning as: System has detected a legal but non-optimal population of DIMMs (for example, 1 DIMM, 6 DIMMs, 4 DIMMs in slots 1, 2, 5, and 6, etc.). The system will run with all memory accessible but will experience sub-optimal performance. The System Memory section of the manual continues: General Memory Module Installation Guidelines: To ensure optimal performance of your system, observe the following guidelines when configuring your system memory… FBDs must be installed in pairs of matched memory size, speed, and technology, and the total number of FBDs in the configuration must total two, four, or eight. The machines still ran fine (and way faster than before with the new RAM) and both saw all 16GB of total RAM (because I installed a PAE-enabled kernel last night, as well). Of course, the solution to make this warning go away was to simply put 8x2GB DIMMs in one server and 4x4GB DIMMs in the other (my smokin' hot former school teacher wife actually figured that math problem out in about
