I do not see any info from HP or any third party sources about it working with the 900 series.

You might want to download the HP document "An examination of the dual-core capability of the new HP
xw4300 Workstation" (4AA0-0363ENW, May 2005). This work compares the Pentium 4 672 (3.80 GHz) with HTT with the Pentium D 940 (3.20 GHz). This should help you to determine if such an upgrade would provide the added performance that you are looking for.
The difference between a 840 and 940 is that the 840 is 90 vs 65 nanometer technology, has 2-1 MB vs 2-2 MB L2 cache, and uses HTT vs N/A. Both will fit the CPU socket, but HP tech support should be consulted about the cooling fan.
