The Z690 Apex is built for pushing performance to its limits, with dual DIMM ports designed to support higher memory overclocks. For gaming purposes it offers little benefit beyond the option of adding more RAM later, making it less appealing compared to other options. Purchasing a motherboard over $700 for this reason might not be worthwhile.
The board works well from a RAM standpoint, with each slot functioning as its own channel, enabling standard dual-channel performance. But it’s a $720 model built for maximum overclocking and is way beyond what most gaming systems need. There are just two RAM slots, which simplifies stability during intense overclocking attempts.
I've been experimenting with these boards, starting with the Z690-E. I discovered they're compatible with PCIe 5.0 SSDs even though they aren't officially available, so pairing my Samsung 980 Pro lowered the GPU's PCIe lane to x8. I didn't need watercooling or white cases, which left me with the Z690 Hero—though it's sold out and I don't like its appearance. The Apex costs $120 more than the Hero, so I bought it because it was still in stock. Now I'm considering the Hero for 4K gaming, wondering if its single-channel DDR5 XMP profiles work with it since they're designed for dual channels.
Chose to create a future-ready setup that I can maintain for several years, purchased a 12900k and plan to run at 4K resolution. Opted for DDR5 since higher-end DDR4 remains costly.
Future proofing doesn't really exist. When DDR5 speeds arrive, you'll likely need a more recent CPU with improved memory support, possibly along with a new motherboard. Two DIMM slots arranged in pairs is dual channel. With four slots, you usually get one channel for every two, making it dual channel too—just offering greater capacity. Quad channel is available but mainly for specialized server boards and high-end CPUs.
