OMEN HP 45L Gaming Desktop GT22-3000t PC

I would like to upgrade my pc to the max.

I heard for proper upgrade i will need to upgrade the motherboard, psu, cpu to use the (AMD Ryzen 9 9950X3D)  does anyone know or (have experience with doing the upgrade) whats the best motherboard and products I would need to run the AMD ryzen chipset.  I also would like to know if i can upgrade my ram any higher and is there any benefits of having secondary storage in the pc for gaming purposes. Specs are below.  Thanks in advance for anyone willing to help!

@MiaFan4L,

Welcome to our HP Community forum!

Your OMEN 45L GT22-3000t uses the WildheartOC motherboard (SSID 8CF3). According to HP’s specs, this board only supports two CPUs:

• Intel Core Ultra 7 265K (125-watt TDP)

• Intel Core Ultra 9 285K (125-watt TDP)

These are very capable processors -in fact, the Ultra 9 285K is one of Intel’s newest and fastest CPUs. There’s no upgrade path to AMD Ryzen on this system, since that would require replacing the entire platform (motherboard, CPU, and potentially the case wiring due to HP’s proprietary cabling), so that would not be a sensible option.

Let's Talk About performance: Comparing your CPU (Ultra 9 285K) against the AMD Ryzen 9 9950X3D, you’ll see that your Intel chip is already faster overall. The 9950X3D may have an advantage in a handful of gaming workloads due to its 3D V-Cache, but outside of that niche, your 285K matches or exceeds it. In short, moving to a 9950X3D would not be an upgrade in this system -it would at best be a sidegrade, and require a complete rebuild.

On memory (RAM): You already have 64GB DDR5-5600 (4×16GB). That’s the maximum this board supports, and more than enough for gaming. Any gaming.  Trust me on this. Going beyond 64GB would not improve performance unless you were doing extraordinary heavy workstation tasks (video editing, 3D rendering, scientific computing, etc.).

On storage: Yes, adding a secondary SSD or HDD can be useful for organization and convenience. I would recommend this. A fast Gen4 NVMe drive for your OS and favorite games (which you already have), plus a larger secondary drive for bulk storage (games, media, backups), is often the ideal setup. It won’t make games “run faster,” but it helps with space management.

---

Bottom line: You already have a top-tier CPU, GPU, RAM, and PSU -there’s sensibly really nothing to upgrade on this OMEN except adding a second SSD/HDD for storage. If your goal is maximum gaming performance, you’re essentially at the ceiling already.

Please, don't fall into the AMD marketing myth trap -assuming “Ryzen 9 3D = ultimate gaming” without realizing:

1. The Intel Core Ultra 9 285K is already newer and better overall. 

2. Switching to AMD would require tossing the whole HP motherboard.

Hope this was helpful.

Kind Regards,

I don't entirely disagree with your argument, but I think it would be a stretch to call AMD's current supremacy in CPU performance (in games) a myth. Given that most popular games are largely gpu-bound, the difference between the two companies' top-tier cpus is usually nigh-imperceptible, but we can't really use such examples to make any meaningful conclusions about CPU performance. In games where CPU performance matters more than GPU performance (Crusader Kings, Rimworld, the Warhammer strategy series, etc), the 9800X3D and 9950X3D do reliably outperform the 285k by a not-inconsiderable margin. As you mentioned, this is largely due to their "3D V-cache" technology, which allows more information to stay in the CPU instead of being offloaded to RAM. This, on top of their excellent single-thread performance, usually gives them the upper hand in gaming.

Intel does have outstanding multi-thread performance, but most games can't take advantage of this because much of what a game needs to process is dependent on other variables that are processed by taking in other variables that result from processing yet more variables and so on and so forth; that is to say, there are relatively few things in games that don't interact with each other and can therefore be independently processed. Certainly some things can; developers often do isolate "chains" of calculations that don't interact with anything else and offload them to other threads in order to optimize performance, but the bulk of a game's cpu load is almost always (if not always) confined to a single thread.

Sorry for the long reply. I don't mean this as an attack on your response — I thought it was well-crafted, and I would agree that switching to an AMD CPU on the Omen 45L is much more trouble than it's worth for most users. I just love these kinds of topics and couldn't help myself lol

For what it's worth, I do have an Omen 45L with a 5090 and an Intel Ultra 285K. It's a fantastic rig, though some VR experiences can still bring it to its knees.

No worries at all! Thats why i am here. The more information the better! What are your thoughts on the motherboard? since we are on the subject of the 45L i feel like the networking and the motherboard are causing the computer to not reach its full potential. (As for me it is just for gaming and nothing else) the 4 sticks of 16g ram i feel (from what i hear) would be better with two 32g or higher if less (latency) am I correct?

@MiaFan4L,

Yes, 2x16GB (dual-channel + dual-rank) beats 4x8GB RAM. Your 4x16GB RAM is perfectly suited for gaming, and I'm not sure if replacing it with 2x32GB would give you a noticeable RAM performance increase.

Unless you crunch numbers all day long, 2x64GB RAM (if your PC is even compatible with that) is not going to give you any better gaming performance.

And as I mentioned in my previous post, your Intel Core Ultra9 285K matches the Ryzen 9 9950X3D in gaming performance.
