Strange Ram Upgrade Problems

[Gburgfire1]

So, I had a blue screen Memory failure a few days ago and decided to take the opportunity to upgrade the RAM while replacing it. I bought the exact same RAM modules that came with the Victus (Corsair Vengeance LPX DDR4  3200 MHz 1.35V). The only difference that is the modules that I bought are 2x 16GB modules for a total of 32gb for an upgrade from 16Gb and the version number on the back of RAM is different with the new sticks being 4.33 and the ones installed in the computer being 5.32. Upon install, computer booted normally, but computer reads each module as only 8 Gb, and also downclocks both modules to 2133MHz. I tried some trial and error and removed one of the modules and tried running only a single module, and that one then detects as 16Gb, but is still downclocked to 2133MHz. Can anyone provide some help with what's going on? Thanks!

And now you know why the best practice for a memory upgrade is to purchase memory modules that are guaranteed to be compatible.

Contact the vendor to see if they will; help you find guaranteed compatible memory modules.

Your experience and mine in the past are why I have specific methods of upgrading memory.

1) if I am upgrading a laptop I do as I described above

2)If I am upgrading a DIY motherboard, I read the memory compatibility list that is associated with the motherboard in the support documents.

If the Desktop PC is a factory prebuilt unit, I go to Kingston memory or Crucial memory to see what they guaranteed as compatible. 

Something to note is that if you purchase  Fast gaming memory instead of standard memory, the modules will downclock to the default memory  bandwidth of the chipset on the applicable laptop system board or desktop motherboard.

Your Reno motherboard is advertised as supporting up to PC4-25600 (DDR4-3200), but there might be something in the primary or secondary timings of the higher storage capacity module that limits it to 2133 MHz. 

KIngston memory does not sell compatible upgrade modules for your Victus, but Crucial Memory does.

Erico- Thank you for your response, I agree with your assessment for best practices for a memory upgrade/repair, which is why I bought the same exact RAM (Crucial Vengeance LPX) that shipped with my prebuilt Victus computer from the factory as I referenced, so obviously it would have to be compatible. I am wondering if this could be a BIOS issue. Everything on my system is up to date, but I wonder if HP itself needs to release a BIOS update for this board as this might be a bug of some kind.

"which is why I bought the same exact RAM (Crucial Vengeance LPX) that shipped with my prebuilt Victus computer from the factory as I referenced"

I disagree with that statement.

Were the new modules the same storage capacity? You stated that they were not.

If they were, that would make them the "same exact RAM (Crucial Vengeance LPX) that shipped with my prebuilt Victus computer"
