Unique case of memory speed enhancement Overclocking RAM peculiarities Unusual patterns in performance tweaks
I've been experimenting with boosting my RAM recently after using the latest CTR tool to maximize performance on my R5 3600. I achieved 4.4Ghz at 1.168v, which is stable. Concerning memory, I own two sets of Corsair Vengeance RGB 3000MHz CL15 16GB. One set is v5.32 and the other v5.39, likely based on version numbers. The v5.32 model consistently fails to exceed 3200Mhz regardless of settings or voltage. The v5.39 version can reach up to 3733/66 but isn't stable. I've settled on 3600Mhz for now (stock is 15-17-17-36). Everything seems normal until I switch between dimming slots 1 & 3 versus 2 & 4. In slots 2 and 4 it runs at 3600Mhz, but in slots 1 & 3 it caps at 3200Mhz. Could this be due to the memory controller or the motherboard? I tested a kit that wouldn't exceed 3200Mhz in any slot, and it worked fine at 3600Mhz in slots 2 and 4, but not in 1 & 3. The newer kit does 3600Mhz in slots 2 & 4, yet still hits 3200Mhz in 1 & 3. This seems quite unusual. Any advice? I’m planning to upgrade soon to a 32GB 3600Mhz RAM and eventually a B550 motherboard with a new 5600X later.
The RAM is designed for a 3000MHz boost, but pushing it to 3001 might compromise its reliability. I doubt it will perform significantly better than the rated speed, and even a modest 200MHz overclock won’t make up for any instability issues.
The kit is designed for a minimum temperature of 3000C15 with no upper limit. Performance can vary widely—some units excel while others underperform. For optimal results, start with slots 2 and 4, as the diy chain topology boards consider slot selection per channel. Unlike T-topology, this setup pays attention to slot usage.
I'm trying to understand why one memory channel performs better than the others. I don't want to invest in four 8GB sticks running at 3600Mhz only to discover that one channel doesn't reach that speed. I'm looking to figure out if the issue lies with the motherboard, RAM, or CPU. I'm planning to get a 3900X soon and will see how it affects my setup. Later, I'll also add a B550M motherboard for future upgrades.
The issue likely lies with your motherboard's daisy chain setup. For optimal performance, choose slots 2 and 4. This configuration works best with a 4-drop setup, but it can be challenging with a 4-drop arrangement. Using a 2 by 8 slot layout in each channel helps avoid signal interference. If your board doesn't support high speeds, consider a 4x8 at 3000MHz or opt for the upgraded 2x8 with overclocking.
