I don’t have deep expertise in PC mechanics, but I can build one and handle troubleshooting well beyond what most users know. Many people wonder if RAM is still necessary given the compact size of modern devices. Manufacturers often avoid adding a PCIe slot for RAM because it would take up valuable space that could otherwise hold storage or other components. Instead, they stick to standard memory slots like DDR4 or DDR5, which are designed for performance and compatibility.

According to my understanding, RAM remains much quicker than SSDs, even when compared via PCIe.

Bandwidth isn't sufficient at present. DDR4 RAM typically handles 10-20GB per second, whereas NVMe delivers around 2.5GB per second under ideal conditions. The processor manages RAM directly*, bypassing the need for a separate bus and decoding process on the SSD controller, resulting in significantly faster response times (nanoseconds versus milliseconds). * = Contemporary CPUs handle control independently. Older setups relied on a dedicated chip to relay RAM data to the CPU. As RAM speed requirements grew, controllers shifted to direct CPU communication.

Dual channel 3200 RAM delivers roughly 50 GB/s speed. A premium SSD could reach about 5GB/s, creating a noticeable difference. The main reason to think about this lies in cost. SSDs are more affordable per unit of storage than RAM. Intel Xpoint sits between RAM and flash SSDs, available in server setups as a budget RAM alternative. Another issue is durability. Flash SSDs might only endure a few write cycles before failing, whereas RAM is essentially limitless. In this scenario, flash SSDs would degrade rapidly.

RAM should be near the CPU for quick communication and reduced delay. The CPU shouldn’t search for RAM across the entire PCI-E bus, as this would slow things down and could confuse the CPU.

I've been testing MemTest extensively on my 3200 CAS14 machine, but I haven't managed to pinpoint the issue—my results show around 18GB per second, which matches the figure I saw online. Could be per stick?

Memtest evaluates performance based on channel count, but real-world speeds often lag behind theory. Your dual-channel 3200 setup shows a measured throughput of about 45GB/s, which aligns with practical software testing results.
