xw4300 processor series question

Hi, I have an xw4300 that I would like to upgrade the CPU on. It currently has a p4 3.0ghz in it. I am looking at the pentium Ds as the 955x will take it. Now, in the manual, it claims the board will take the 840 PD. The question is, will it take the 900 series dual cores??

Re: xw4300 processor series question

All of the information that I have show that the highest end chip the CPU supports is the dual core 840 (Intel Pentium D processor 840 (3.2 GHz/1 MB, 800 FSB, Dual Core)

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

Re: xw4300 processor series question

In response to the June 19 reply, that states that the responder has not seen anything from HP or 3rd party sources that support dual Pentium processors above the 800 series, according to HP QuickSpecs for the xw4300, DA-12260 versions 15 (4/1/2006) and 22 (5/25/2007), the Pentium D 940 (3.20 GHz, 950 (3.40 GHz), and 960 (3.60 GHz) were available options. The xw4300 datasheet of March 2006 also showed the use of 900 series. Sometime during the first 3 months of 2006, HP must have changed from offering the 840 to the 900s.

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.
