Z440 memory modules question

[NonSequitur777]

@1patriotofmany,

Outstanding!

I am truly glad that you figured out things (my M.O. too!) and successfully upgraded an HP Z440 Workstation with a souped-up Intel Core processor it was never designed for!

UserBenchmark has this to say about the i7-6900K (in 2025, mind you), and I quote: "Very good average bench - The Intel Core i7-6900K averaged just 14.1% lower than the peak scores attained by the group leaders. This is an excellent result which ranks the Intel Core i7-6900K near the top of the comparison list."

As we speak, I have mothballed my HP Z440 Workstation, but I can resurrect it if you still need my BIOS settings -let me know.

Kind Regards,

NonSequitur777

Thank you NonSequitur777!  I don't need them for now, but I may have questions about some of the settings down the line, a few of them I don't understand.  Regards and many thanks for the idea and help!

NonSequitur777 Had a couple interesting observations.  When i swapped out the 16GB memory modules and put in the 32GB modules, the memory speed dropped from 2400 to 2133. Why would that be, they are 2400 speed modules? I think the 16GB modules were 2666 rated

  Also when I ran user benchmark below the score it says something about cpu background usage is not great for the test.    

There's a bunch of rom modules in the bios that are set to on. If I shut them off will the computer still work right? Seems like this replacement board must of had way more security or something going on where it came from.

@1patriotofmany,

Sorry, didn't see your message in a timely manner -HP's notification software leaves to be desired.

I am not sure why the 2400 to 2133 switch happened, unless one (or more) of your 32GB RAM sticks are actually 2133-rated RAM modules: better check each individual RAM stick's part number.

Kind Regards,
