5950x on x570 board, intermittent lock up with DRAM led lit
Computer Model: Desktop GPU – EVGA RTX 3080 CPU – Ryzen 9 5950x (16 cores, 32 threads) Motherboard – Asus x570 Crosshair VIII Hero (Wi-Fi) BIOS – Version 4501 (04/19/2023) RAM – G.Skill Trident Z Royal 3600 CL14 F4-3600C14D-32GTRG Power Supply – Quiet! Straight Power 11 Platinum 1000W BN644 Fully Modular Case – Lian Li 011 Dynamic XL Operating System & Version – Windows 11 Pro GPU Drivers – GEFORCE GAME READY DRIVER – WHQL Driver Version: 536.67 Description of Initial Issue: Constructed the system roughly three years ago; functioned adequately for about one and a half years before ongoing troubleshooting began. Occasionally it freezes, screen becomes unresponsive yet remains powered on, ignores power button activation, and resets only via PSU switch. Debug codes fluctuate between AA and 00. The yellow DRAM indicator flashes intermittently, appearing dim or absent, resembling a candle flickering weakly in the wind. Troubleshooting Steps: Updated BIOS, performed BIOS reset, reinstalled OS and drivers, submitted RMA for CPU only. Downclocking RAM provides marginal improvement, but experts suggest it should operate normally at the 3600 MHz clock speed. Seeking community insights. Note: The motherboard model listed is Crosshair VIII, not VII as previously shared. Updated August 7, 2023 by Krodmandoon – Corrected board identification
CL14 performs well at 3600MHz on Ryzen, but I suggest checking higher timings in the CL16 and CL18 ranges. This chip has a 14-15-15-35 profile which is quite demanding... An aggressive Intel XMP setup may not be suitable for Ryzen as these processors can handle much more aggressive settings. Start with 18-22-22-42 first.
I thought the clock speeds could be the problem, I tried cl16, perhaps it wasn’t enough, I’ll give it another shot. Edit: I’m unsure if updating will help you, but I have some ideas about the flickering LED. It seems similar to a hardware fault, though it kept happening even after swapping memory and power supplies. It’s possible I’m mistaken, but it’s definitely not just timing issues.
