Looking to do a RAM upgrade and install additional RAM in my machine - max capacity / compat

[Rpugh090289]

I have the HP OMEN 30L Desktop GT13-1047na PC (4V9T8EA)

im looking to upgrade the RAM currently at 16GB  -  wanting to add another 16GB in the form of 2x8GB sticks, 

what is the maximum the system can support, ive seen conflicting data on my pc some say 128GB others say 32GB so im confused,  also i tried some lexan chips i had off amazon for another device but they did not work, the PC would not register this at all,  so not sure if its not compatible for any reason or not, My bios sees 4 x ram slots and only 2 populated

so i assume it should be plug and play 

Any help would be much appreciated RAM detail below was what i tired 

Lexar ARES RGB DDR4 RAM 16GB Kit (2x8GB) 3200MHz, DRAM 288-Pin UDIMM Desktop Memory, PC Gaming Computer High-Performance Memory for Intel XMP 2.0 and AMD Ryzen/CL16-20-20-40/1.35V (LD4U08G32C16LA-RGD)  -

Hi @Rpugh090289,

Welcome to the HP Support Community!

Thanks for reaching out!

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

I understand you’d like to upgrade the RAM on your HP OMEN 30L Desktop GT13-1047na (4V9T8EA) and are unsure of the maximum supported capacity and compatibility. Let’s go through the details to clarify this.

Maximum RAM Capacity

The HP OMEN 30L GT13 series supports up to 64 GB of DDR4 RAM (not 128 GB).

The system has 4 DIMM slots, and can take 16 GB per slot (4 × 16 GB).

RAM Specifications

Type: DDR4 UDIMM (Unbuffered DIMM), non-ECC

Speed: Up to 3200 MHz (system may downclock if faster modules are installed)

Voltage: 1.2V or 1.35V (XMP supported)

Why the Lexar Modules Did Not Work

Not all third-party gaming memory is fully compatible with OEM motherboards, especially those with aggressive XMP profiles.

HP systems can be sensitive to timing/voltage mismatches, so it’s best to use memory that closely matches the factory-installed RAM.

Recommended Upgrade Path

Since you currently have 16 GB (likely 2 × 8 GB), the safest upgrade is to add another 2 × 8 GB kit with the same speed, voltage, and CAS latency as your existing modules.

Alternatively, replace all 4 sticks with a matched 2 × 16 GB kit or 4 × 16 GB kit if aiming for higher capacity.

Testing & Installation

Install the new RAM firmly until the latches click.

Power on and press F10 to enter BIOS → confirm total RAM is detected.

If the PC fails to boot, reseat the modules or try them in different slot pairs.

I hope this helps.
