we won't go into all of the reasons why you may not be able to load these operating systems other than to say that we presume that you have (1) resolved all other hardware possibilities such as hard drive problems (and controller problems

where necessary); (2) are aware of partition limitations for the specific operating system being loaded; (3) dell support you know how to partition the hard drive, format it with the correct FAT and you have run Scandisk; and (4) you have created the necessary boot files to enable upper memory areas as well as load Smartdrv where necessary. This aside, here are some possibilities: Check the systems power supply Check for CPU overheat problems If you are loading Himem.sys in your Config.sys file, http://www.dell.com/support/Article/us/en/04/SLN286634/EN make sure that there are no errors occurring when this file loads. Swap the position of the memory modules and try the installation again. Your computer boots, Windows starts but is unstable. Instability in all Windows versions can be caused by any or all of the following: Power Supply problems A chip on a memory module is beginning to fail or is borderline. Parity of ECC error between memory modules CPU overheat problem Potential video card failure Irregularities with the voltage http://www.dewassoc.com/performance/memory/tshoot_mem_2.htm regulating module on the motherboard *If the motherboard is equipped with its own cache, it may be failing Corrupted Windows device driver or virtual device driver Corrupted Windows swap file (Page file in Windows NT) You hear a continuous beeping sound from your system during power up or boot-up process. A continuous beep tone from your systems motherboard is a sign of memory failure, failure of the memory on your video card or a complete video Card Failure. You may want to verify your settings in the BIOS to insure that there are no errors in the setup before changing the memory. When you start your computer, it continuously runs a ram count without loading the operating system. If, during startup (boot-up) your system continually runs a ram count, starts at zero and runs through the total amount of your RAM memory and then starts over again, this is an indication of any one of the following: Parity mismatch between memory modules ECC memory on a motherboard that doesn't support ECC memory Mismatched memory modules Memory chip failure BIOS or CMOS setting error No display other than a Windows blue screen error (GPF) on the monitor during boot-up. Unfortunately this type of problem has many possibilities. The following presumes that you have tried to boot into Windows Safe Mode and cannot do so. You may want to check the following: Parity mismatch between memory modules ECC memory on a motherboard that

Dell Warning: The current 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 system halted Jenkins (updated 1862 days ago) In 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 memory bios configuration 4:2GB 5:4GB 6:4GB 7:[empty] 8:[empty] I booted the upgraded 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 DI
