Overclocking the Memory Controller
We have moved past the days when 6000MHz was the "sweet spot". With the arrival of the 2026 motherboard chipsets, we are seeing stable 8400 MT/s profiles across most mid-to-high end boards. But frequency is only half the story.
The Sub-Timing Matrix
To truly unlock performance, you must tune the secondary timings. Our testing shows that tightening tREFI and tRFC yields a 12% improvement in minimum frame rates, even if the primary frequency stays the same.
Is it worth the cost?
The jump from 6400MHz to 8400MHz is noticeable in high-refresh-rate gaming (300Hz+) but almost invisible in 4K scenarios where the GPU is the bottleneck.
Core Recommendation: If you have an RTX 5090, your RAM must keep up. Don't choke a $2000 GPU with $100 memory.
