Issue with Asus ROG Crosshair X670E Extreme during Memory Test 00 - Advanced Troubleshooting Failed
Hey everyone,
I've been assembling PCs for about 25 years, and this is the first time in probably 15 of those attempts I've faced a complete roadblock. Any assistance or suggestions would be really valuable.
I've put in a lot of effort reading about what appears to be this fairly typical problem, and I've tried every troubleshooting method I could find (details are listed below the specifications).
About a month ago, I built a new PC without any issues – it was running perfectly until last night. I encountered this error when I first powered it on a month ago, but it was caused by me placing the RAM in A1/B1 instead of the correct slots A2/B2. So far, I haven't experienced any issues, not even a crash, since then.
I was using the EXPO Profile in BIOS before this incident. I'm not running any additional overclocks or making voltage adjustments yet – I hadn't done that this time.
Here are the full specifications (with links to the seller for reference):
- Asus ROG Crosshair X670E Extreme
- AMD Ryzen 9 7950X3D Processor
- G.Skill Trident Z5 Neo RGB 64GB (2x32GB) 6000MHz CL32 DDR5 EXPO F5-6000J3238G32GX2-TZ5NR
- ASUS ROG Strix GeForce RTX 4090 OC Edition, 24GB
- Corsair iCUE H170i Elite LCD XT Display AIO CPU Cooler
- Crucial T700 4TB M.2 2280 NVMe PCIe 5.0 SSD
(Placed in the ROG Gen-z.2 to guarantee available lanes on PCIE_1)
- Corsair AX1600i Titanium Modular 1600W Power Supply
- Cooler Master HAF 700 EVO ARGB Tempered Glass Case
Plus several SATA drives and a second M.2 – Samsung 970 2TB in the Gen Z)
Troubleshooting steps completed:
- Re-seated RAM multiple times
- Re-seated CPU and cooler (confirmed cooler wasn’t too tight, booted without it for a short time)
- Re-seated graphics card
- Changed RAM slot layout; tested each stick individually (8 boots)
- Reset CMOS
- Tried booting from the secondary BIOS (expected default, since I didn’t flash it)
- Flashed BIOS using BIOS Flashback to the latest version released a month ago
- Booted with no RAM installed (still getting stuck on memory test!)
- Left PC running at Memory Test 00 phase for 6–12 hours repeatedly at various troubleshooting stages
- Attempted LN2 mode
- Verified all connections were secure and tight – reconnected most of them
- If I had additional DDR5 RAM, I’d swap it in temporarily, but I don’t have access to any
I’m running out of ideas. If any component was faulty, it would likely be the motherboard or RAM. It’s strange that after a month of stable performance and no issues, it just stopped booting up. I think it might have done a Windows Update last night, but that shouldn’t affect POSTing.
Anyone have suggestions on what to try next?
This is typically a dead CPU or motherboard issue. Hope it isn't your concern. News - Users Share Concerns About Ryzen 7000X3D Overheating and Motherboard Damage Redditors caution that certain AMD Ryzen 7000X3D chips may fail on Asus and MSI boards. Read more forums.
It turned out a pin was entirely absent from the socket on the motherboard. It wasn’t broken—it simply never existed. This appears to be a clear manufacturing and quality control issue, confirmed by the retailer during testing. Rather than swapping the motherboard, Asus is asking for five to twelve weeks to evaluate and repair it, which violates Australian regulations. Consequently, I’ll be without my system for up to three months while they try to justify the delay and avoid fulfilling the warranty. Many others have reported similar problems with their current warranty procedures.
Replacement will happen since there’s no alternative, but I shouldn’t have to struggle for it. This situation is likely contributing to the widespread issues people are seeing online, including these same problems Asus seems unwilling to address.
Sorry—I’ve been an Asus enthusiast for two decades and always purchased their products, including mice and headsets. Never again.
