“The Intel Xeon processor 5400 series is compatible with Intel® 5400, 5100, 5000P, 5000V and 5000X series of chipsets.”
The Poweredge 1900 uses motherboard OTW855 and includes the Intel 5000P chipset which supports both 1066 & 1333 FSB. This begs the question, are we simply missing BIOS support from Dell for these newer processors?
The 5200 and 5400 series Xeons use a 45nm die size, which means they need/use a lower voltage. The 1900 was never offered with these processors, so I'd go out on a limb and say that the system doesn't have the ability to lower it's voltage (to the processor socket) to match the voltage requirements of the newer Xeons.

5300 series includes L version processors which are low voltage. Normal 5300 series VID range is 1.0 - 1.5V, L Versions 0.9 - 1.25V. 5400 series go from 0.85V - 1.35V includng both normal and L versions. 0.05V difference is not enough to keep Harpertown from running on this board. Dell would rather you spend money on new hardware rather than supporting this upgrade.
I just bought a PowerEdge 1900 and have been looking at options for CPU's upgrades. I did notice in BIOS 2.4.3 changelog below:
Added support for Quad-Core Intel(R) Xeon(R) Processor 5400 series E0 Stepping
* Added support for Dual-Core Intel(R) Xeon(R) Processor 5200 series E0 Stepping
* Updated Quad-Core Intel(R) Xeon(R) Processor 5400 series C0 Stepping Microcode
* Updated Dual-Core Intel(R) Xeon(R) Processor 5200 series C0 Stepping Microcode
Doesn't that mean you can run a 5400 CPU or only for the later revisions of the PE 1900 ? I was hoping I might be able to run a Xeon X5470 1333FSB 3.3Ghz Quadcore .45NM E0 CPU.
Has anyone tried to use Xeon CPU not listed on the dell Poweredge(PE) 1900 compatibility list ?
Im mostly curios if it is possibly to run the low voltage Xeon on the PE 1900, e.g. L5335, L5320, ...
I contacted Dell Support here is my email correspondence with them:
"The PowerEdge 1900's only support the 51xx series and 53xx series Xeon processors. PowerEdge 1950 however does support 54xx Xeon processors.
Here are a few processors that has been tested to work with the PowerEdge 1900:
"There is a newer motherboard revision to support this processor.
This PowerEdge server(ServiceTagRemoved) was purchased back in 2007 and it doesn't support Intel Xeon X5470 or Xeon E5450.
Also, if the front of your system chassis is labeled with a "II," your system is upgradeable to the Quad-Core
Intel® Xeon® Processor 5300 series.
"It will not be able to support Intel Xeon X5365 unless it has a numeral "II" label on the front chassis."
We have 2 PE1900's both II's (little roman numeral on lower left of front behind faceplate).
Numeral designates the series and will be nothing (I), II or III. One PE is a dual Quad Xeon E5335 and the other is a dual Dual 5130.
These are both unchanged from their original configurations and are both 2.0GHz.
The BIOS of the 5130 is 2.5.0 and the E5335 is 2.0.1.
We will be upgrading to either E5345's or higher. I think you need to have the III series to run higher than the 5300's.
