Are Pentium D 9xx instructions compatible with Windows 10

Hi 

I have an Asus Motherboard P5P800SE with Pentium D 820 2.8ghz which is missing the instructions required for Win 10 installation. I think some of the Pentium D 9xx might have them but would like to confirm if any of these 65nm 95w have prefetchW - PEA-NX-SSE2 - LAHF/SAHF and CMPXCHG16b.

 

Thanks

Which D 9xx?  You really should not be using that processor at all on W10.  2005 is a long time ago.

Hi

My Pentium D 820 is only missing the prefetchW and CMPXCHG16b instructions everything else in my PC is compatible and my PC is in mint condition running very well with SSD. I know that these instructions were required as of win 8.1 when upgrading from win 8 as per many that I found on forums. One person had same pentium D 820 and couldn't upgrade to 8.1 because of this and used a Pentium D 950 and was able to install and it ran well.

As per Asus the last pentium Ds that are compatible with my MOBO are the 9XX. What I am not able to find is if it's only the 950 or 960 or if they all have theses instructions. I'm trying to find the list of CPU instructions for the 900 series to make sure before I buy one.
