The Asus Maximus Z690 Apex is used as the test platform, which was already able to stably overclock RAM modules with Micron 16 Gbit RevA ICs to 5600 Mbps in the past. As with the other DDR5 tests, an i9-12900K overclocked to a static 5.1 GHz on the P-cores, 4.9 GHz on the cache and disabled E-cores serves as the CPU.
Unfortunately, the overclocking result of the T-Force VULCAN modules turned out to be a bit less than expected with a maximum stable clock rate of DDR5-5400. 5600 still boot, but can not be stabilized with up to 1.435 V VDDQ. In the end, I accepted 5400 Mbps at 1.35 V VDD and VDDQ as the limit and tightened the timings as much as possible.
At least the timings can be optimized a bit more relative to the XMP profile, with primaries 34-39-39-49. However, the command rate cannot be reduced to 1T with Micron RevA (at least at the moment). In turn, the secondary timings can be tightened relatively strongly, with tRRD_S and _L at 4 and 6, respectively, and tFAW 16. However, the refresh timings tRFC and tREFI as well as the tertiary timing tWRWR_sg, which is important for bandwidth, again require a somewhat more conservative approach, typical for this memory IC. Finally, some latency can be saved with “Round Trip Latency” and so the config was sent into the benchmarks.

For better clarity, the following abbreviations are used in the diagrams:
- 12900K: Intel Core i9-12900K CPU
- 51/0/49: Multipliers for P-cores x51, E-cores 0 (deactivated), cache x49 at BCLK 100 MHz
- XPGL: XPG LANCER RGB DDR5 modules from ADATA
- DPR: Dominator Platinum RGB DDR5 modules from Corsair
- FB: Fury Beast DDR5 modules from Kingston
- DR: Dual-Rank, if not specified Single-Rank
- 3600c14: DDR4 configuration with 3600 Mbps and tCL timing 14, see screenshots for all timings
- 1T, 2T: Command rate 1T or 2T
- *: completely manually set subtimings, see screenshots
- G1, G2: Gear 1, Gear2 – ratio between IMC clock and RAM clock, Gear 1 = 1:1, Gear 2 = 1:2
