The 3600 CL18 offers higher bandwidth, while the 3400 CL14 excels in low latency. For gaming, the 3400 CL14 is generally superior. For productivity work such as code compilation, the 3600 CL18 provides better performance.
It's similar to contrasting a vehicle that struggles to start but accelerates quickly with one that speeds up fast but reaches a slow top speed. Quick acceleration suits racing tracks, while high top speed is ideal for extended journeys.
The latency variation is minimal—about 8.23 versus 8.88 ns (roughly 7%). Speed variation is around 5%. In real-world use, you probably won’t see a difference unless you’re testing performance.

The 3600 Mhz CL18 resembles a 3200 Mhz CL16. The type of stick—single rank or dual rank (1Rx8 or 2Rx8)—affects performance, with dual rank options offering slightly better results. The gap in performance will be smaller than the figures mentioned earlier. Latency refers to how quickly the device reacts to data requests or storage operations. Frequency describes the speed of data movement between the stick and the CPU after a transfer begins. When apps need many small memory fragments, lower latency becomes more advantageous. For applications handling large data blocks (like megabytes), latency has less impact because delays such as 8 nanoseconds versus 10 nanoseconds are minor compared to larger losses like 50 nanoseconds. With dual rank, the CPU’s memory controller can handle requests on one rank while transferring from another, allowing data readiness sooner. This reduces the waiting time (8–10 ns) before transfer starts, making latency even less critical.
In reality, the 3400MHz setup is expected to perform better across all metrics. Even though it operates at a lower frequency, Samsung B Die ensures precise timing, which significantly boosts speed and bandwidth. While the exact frequencies are close, the tight timings on the 3400MHz model give it an edge. You can confidently use 3800MHz [email protected] settings—it should function smoothly and outpace the 3600MHz version. The higher voltage is manageable as long as temperatures stay under control.
Updated: I actually tested it because I was getting bored. The main clock speeds came from the first memory kits I discovered with those specs, so I used 3400MHz CL14-17-17-35 and 3600MHz CL18-22-22-42. The 1T Command Rate was applied to both, and all other settings were left automatic. For the 3400MHz kit, the benchmark chip I had doesn’t list a ratio at that frequency, so I used 3466MHz and adjusted the BCLK down to hit 3400MHz. I also tweaked the CPU and cache multipliers, but the speeds were about 10MHz higher—keep that in mind. Remember, your motherboard’s settings can change these numbers a lot. This test ran on one memory rank board in Linpack Xtreme 64. The Quick 2GB test was used. For the 3400MHz CL16 vs 3600MHz CL18, the main variation came from each run. The Aida64 Cache and Memory tests also showed results. 3400MHz CL14 vs 3600MHz CL18 mostly differed by consistency; the 3400MHz kit performed slightly better overall. If prices are similar, opt for the 3400MHz model. But if it’s much more expensive, the extra cost may not justify the real-world gains. Also, a 3200MHz CL14 would be noticeably faster in Linpack but could have higher latency and read rates because of lower tRCD values. On average, it delivers around 198.8967GFlops at 46682MB/s with 41.2ns latency—just don’t worry about copying the screenshots. Keep in mind, your memory controller and board limits set the ultimate ceiling; it’s best to know what you’re working with.
