Error encountered during MemTest86 Pass4 Test7.
Hey! I built a new gaming setup and after posting, I updated drivers and software. I ran Cinebench, Heaven, and Superposition benchmarks—everything was fine until I started playing Valorant. First, my PC wouldn’t boot, so I removed two RAM sticks and it worked perfectly afterward. After swapping them back to the original positions and using all four RAMs, it booted successfully. I expected nothing to go wrong, but during a Valorant session I suddenly got a BSOD. I ran Passmark Memtest 86 on my RAMs and here’s what it showed… The issue seems related to memory stability or corruption. I’m having trouble finding the exact error codes, but thanks for your help!
It seems the RAM is faulty. You have options—diagnose which stick is defective or swap them all. Current memory might still be covered under warranty with a restriction like “only one.” If you end up discarding everything, consider buying a 2x16 module since two slots can perform better than four.
There are many elements influencing performance beyond just the stick configuration. The choice between single and dual rank sticks matters, along with their speed ratings and memory layout quality. I generally prefer 2x16GB for better compatibility and future upgrades. However, if it supports 4x8GB, it should perform comparably or better than 2x16GB under the same memory speed. For Ryzen processors, keeping memory between 3200 and 3800 MHz is ideal, so extra frequency gains from more DIMMs aren't crucial for everyday use. Overclocking two sticks can boost their speed, but it doesn’t improve overall performance in normal scenarios.
I'm in agreement, I went for four sticks to achieve a dual rank.
Consider this classic approach: remove every memory except one stick and run them sequentially. The faulty one will act up. It's also a way to check RAM performance, proving more responsive than memtest86 yet significantly slower. Edited July 31, 2022 by Bombastinator
This applies mainly to Intel systems because they lack a strict frequency ceiling. AMD generally respects its FCLK limits before memory architecture constraints become an issue, particularly with 4 DIMMs—especially when using XMP profiles. On AMD platforms, performance peaks around 3733–4000MHz, while most daisy-chained boards settle between 3733 and 4000MHz depending on the model. Dual-rank advantages are significant; they add roughly 300–400MHz with identical timings. For dual-rank builds, you'd typically opt for premium kits that support Samsung B DRAM or Micron-based options, or higher-end 2x16GB configurations priced around $125–150 versus $200 for 4x8GB. I’d still favor a 2x16GB setup myself. This is mainly about memory compatibility and stability rather than overclocking complexity—both require tweaking tRDRD_DD and tWRWR_DD instead of tRDRD_SD and tWRWR_SD.
Initially they seem more affordable, but later it becomes clear they’re not. I assumed most 16GB DDR4 dimms are dual-rank by default. However, that might not always be true.
