RAM Upgrade for HP Omen 25L

[benji5252]

Hi,

I currently own a HP Omen 25L (GT15-2004na) which has two sticks of Kingston Fury Beast UDIMM DDR5-5200 RGB RAM installed (2 x 8GB). The part number is HP52U40S6HA-8FRAE.

I am wanting to replace with 2 x 16GB modules, but I have learned that only HP certified Kingston RAM is compatible. 

Where can I purchase these in order to upgrade my system memory to 32GB?

Also, I am based in the UK

Any advice is much appreciated!

I have an Omen 25L G15-2007 with the same memory, it runs at 4400MT. I added two Kingston 8GB DDR5-5200 Fury Beast modules, the PC runs and is stable but the clock speed is 2000MT. I've seen comments about the clock speed reducing with non HP parts also that HP don't offer RAM upgrades for the Omen 25 series. Why provide 4 slots and claim that 128GB can be fitted?

Hi @Not_Turing,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your PC!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Check for BIOS Updates:

• Ensure the BIOS is updated to the latest version from HP Support to improve compatibility and performance settings related to RAM.

Enable XMP Profile:

• Access the BIOS settings upon startup.
• Look for memory settings, typically under "Advanced" or "Performance."
• Enable the XMP profile. This option might appear under various names depending on BIOS version but often called Memory or RAM settings.

Use Matching RAM Modules:

• If possible, use identical RAM modules from the same manufacturer and speed rating to avoid clock reductions.
• Alternatively, ensure all modules have compatible timings and voltages listed in their specifications.

Explore HP Configuration Support:

• Verify HP’s official documentation regarding maximum capacity and memory speed for your specific model to ensure expectations align with official support.I hope this helps.

Hi Kuroi_Kenshi,

Thank you for your response. I have actually managed to find the HP part(s) required (N27718-001) it took some finding too. They are very expensive when compared with the "generic" Kingston module. Hopefully when fitted the clock speed won't be reduced.

We'll see.

@Not_Turing, Welcome to HP Support Community,

Thank you so much for posting your query! My colleague @Kuroi_Kenshi is currently out, but don't worry – I’ll be taking over and making sure we get this sorted for you.

Glad you found the right HP-certified RAM (N27718-001). It should fix the clock speed issue you had with the generic Kingston RAM. It’s pricey, but it’s designed to work perfectly with your Omen 25L, so you shouldn’t have any speed problems after installing it.

Once installed, double-check your BIOS to make sure the RAM is running at the full 5200 MT speed.

I truly hope these steps help get things back on track. If you have any questions or need any further clarification, just let me know – I’m happy to guide you through it and make sure everything works perfectly.

Take care, and I hope you have an amazing day ahead! 😊

Problem solved? 🎉 That’s fantastic! If you could mark this as the Accepted Solution, it would help others find their way here faster. And if you found this helpful, a simple ‘yes’ would mean a lot – it makes my day and gives this reply a little street cred! 🏅

Hi,

I Purchased the HP RAM modules and fitted them. With 16GB  fitted the task manager showed the speed to be 4400MT. With four modules fitted the speed has dropped to 4000MT! Why does this happen? 

A reminder, when Generic Kingston Fury memory was fitted the speed was 2000MT.

Hi @Not_Turing,

Thanks for the update and for sharing your experience.

What you're observing is expected behavior due to memory downclocking based on system limitations and JEDEC standards. When all four RAM slots are populated, especially with high-speed DDR5 modules, many motherboards, including those in the Omen 25L series, automatically reduce memory speed to ensure system stability.

This happens because

More modules increase the electrical load on the memory controller.

HP systems prioritize stability over maximum speed when fully populated.

BIOS and memory controller may limit speed based on Intel's memory specifications for 4-DIMM configurations.

To summarize:

Single/Dual DIMMs: System runs at higher speeds (4400 MT).

Four DIMMs: Speed drops slightly (4000 MT) to ensure stability.

With non-HP generic modules, the BIOS couldn’t apply the proper XMP or defaulted to safe settings (2000 MT).

If performance is stable and system temps are normal, there's no concern, and you're still running at excellent DDR5 speeds.

I hope this helps.

Hi, Kuroi_Kenshi

Many thanks for your precise explanation. I hope others find it helpfull.

Would 1 64GB module run faster than 4 16GB modules? - not that I want to do it, I doubt if I could afford it!

 It's a pity the HP customized memory is so expensive.

Many thanks and best regards

@Not_Turing, @Kuroi_Kenshi is unavailable right now, but I'm here and I'd love to help you!

As for your question — a single 64GB module might run at a higher speed than a fully populated 4-DIMM setup in theory, due to reduced strain on the memory controller. However, most consumer-grade motherboards, including in the Omen 25L, aren’t designed to support a single 64GB DDR5 UDIMM module at high speeds — and such modules are indeed hard to find and very expensive.

Bottom line: You’re still running great speeds with full stability, and that’s a win in our book.

Let us know if you have more questions — always happy to help!
