Adjusting performance of Corsair LPX CMK32GX4M4D3600C16
Check if these are Micon, Samsung or other types. For Intel, these parts can likely exceed 3600 MHz, possibly reaching 4000 or even 3866. It's worth trying with a 10900K and Z590, though the RAM height may be a limiting factor.
I’m nearly certain they’re B-die. The only corsair vengeance I’ve heard about matches that outcome. Perhaps focus on adjusting timings first. If you’re willing to move beyond cl16, you won’t notice much improvement at 3866 or 4000. It really comes down to how effectively your RAM can overclock—or even if it will. For example, my 3200 CL15 setup with Corsair LPX stays at stock speed even at 1.5v. I have a solid power supply, a quality motherboard, proper slots, and ample airflow in the case. The main issue is that they won’t budge regardless. The best approach is to stick with your desired speed and CL latency rather than chasing overclocking, unless you have budget available.
You currently have a mixed set of LPX 3200 CL16 units—one with Hynix M and one with Samsung B—each in 4x8 OC to 3600 CL18. I’m testing them now but haven’t seen full stability yet. You mentioned wanting to upgrade the kit to OC 3866/4000 and use the existing LPX in another build.
You could try, but most kits hit their limits quickly. The safest choice seems to be selecting a kit with the settings you prefer and then attempting to push it further. I've found that a 0 MHz boost is typical, and RAM behavior can be quite erratic when overclocking.
You must verify the serial number to confirm if the Corsair board is a B-Die before proceeding. Before any steps, create a bootable memtest86 and ensure your PC boots from the stick, not Windows. Once confirmed, check the timing details of the 4000MHz model. Then perform memtest with at least four passes.
It seems you're comparing two options: 3600/CL16 versus 3200/CL16. Which one offers better value?
DDR4-4000MHz Single-Rank CL19-19-19 (total 28.5) Patriot Viper RGB DDR4-4133MHz Single-Rank CL19-21-21 (29.51) Patriot Viper RGB DDR4-4000MHz Single-Rank CL18-22-22 (31) Corsair Vengeance RGB PRO DDR4-4000MHz Single-Rank CL19-23-23 (32.5) Corsair Vengeance LPX DDR4-4000MHz Single-Rank CL19-23-23 (32.5) HyperX Predator DDR4-4000MHz Single-Rank CL20-23-23 (33) Ryzen Gear Down Mode 4th timing for peak stability should combine all three or opt for the highest speed if unsure, I’m confused, what does that mean? I have two Hynix-C pairs and a pair of B-die in the trash bin.
Using both kits simultaneously with an XMP profile and switching to 36x causes the motherboard to run at 3600 MHz with frequencies 18, 21, 21, and 42 MHz.
