Suits creators needing maximum memory.

This configuration targets professionals who need 192 GB of RAM for large datasets, virtual machines or complex rendering. The full-size ATX chassis with tempered glass panels requires standard desk space. Buyers wanting a smaller footprint should consider alternative form factors.

192 GB DDR5 at 5.50 GHz maximum boost

The memory kit fills all four slots on the X870 motherboard, reaching the platform limit of 192 GB. No further capacity upgrades are possible without replacing modules. Verify that your workload benefits from this ceiling before purchasing.
