SSD DRAM cache failure

What is SSD-DRAM-CACHE-FAIL?

The SSD-DRAM-CACHE-FAIL error is categorized as a high-severity storage drive (SSD/HDD) issue that can significantly impact your PC's stability. An SSD without a DRAM cache (DRAM-less) is extremely slow when writing large files or reading small files. When experiencing the SSD DRAM cache failure fault, users often report sudden system crashes, unresponsive behavior, or a blue screen of death (BSOD). In most diagnostic scenarios, this problem is directly triggered by underlying hardware or software complications such as cheap dram-less nvme (qlc nand without cache), filled slc cache layer and defragmenter running on ssd instead of trim. To permanently resolve the SSD-DRAM-CACHE-FAIL issue and prevent further system degradation, it is highly recommended to follow our step-by-step troubleshooting guide below, ensuring your storage drive (SSD/HDD) components are functioning correctly.

Common Causes

• Cheap DRAM-less NVMe (QLC NAND without cache)
• Filled SLC cache layer
• Defragmenter running on SSD instead of TRIM

Step-by-Step Fix Guide

• 1
  Don't use defrag on SSD (TRIM only)

  Applying the first fix (Don't use defrag on SSD (TRIM only)) addresses the most common root cause of SSD-DRAM-CACHE-FAIL and restores baseline functionality.

• 2
  Upgrade to SSD with DRAM cache (Samsung 990 Pro, WD SN850X)

  If the problem persists, proceeding with the remaining steps ensures all edge cases related to storage instability are covered.
