Problem with starting PC via XMP settings.
Problem with starting PC via XMP settings.
Hi All, I have the following hardware: Gigabyte X670 AORUS ELITE AX AM5 ATX Motherboard AMD Ryzen 9 7900X 12-Core AM5 4.70 GHz Unlocked CPU Processor G.Skill Trident Z5 32GB (2x 16GB) DDR5 6000MHz CL36 Memory I have had issues since I got it where the pc boots fine, shuts down fine, and starts from a shut down fine. But takes a LONG time to reboot, and often when it reboots it comes up with overclocking failed. Then you go into bios, don't change any settings and it comes back. Lately this has gotten even worse to the point that it actually crashes and I have to power cycle the pc several times to even get it to post. When it doesn't post the dram light is on the motherboard, which is usually on until it posts. Once it boots into windows, i have no issues. Until tonight where the pc fully crashed for the first time, no blue screen and wouldn't post. Troubleshooting: Tried all major versions of Bios as well as the newest version, none appear to affect the issue at all. Tried upping the voltage of the memory to see if it was a stability issue, no dice. Tried undeclocking the ram to 5600 or 5200, and no change to the issue. Tried all variations of settings that I have found online, no change. Tried starting with one ram stick at a time, moving their slots (currently in the A2-B2 slots as suggested by manufacturer). The only thing that works is turning off xmp completely (meaning running at a sluggish 4800mhz). However when rebooting the same initial issue arises where I have to hard power off my pc then on again after a reboot to get it back up and working. Anyone got any ideas or additional steps of troubleshooting that I could try?
Is there a version of the RAM designed for EXPO? It seems to fit better with AM5, and G.Skill is listed on the QVL.
I've attempted to turn on EXPO too, but the same problem persists. The main post has been updated: my PC continues to restart into a black screen. I must manually power it off, then turn it back on—it restarts again. Even when XMP is disabled, a case with Gigabyte still works. I'm still trying to figure this out.
The RAM isn't functioning properly even with auto settings enabled on a 4800MHz system, and everything appears to be set to auto. It seems the memory stick might be faulty.
However, when using Windows and it boots up, I can play games without issues. Wouldn't it be more likely to crash if there was poor memory? I was considering a motherboard problem.
I'd consider a different kit first. The Ram kit seems most likely involved. It's possible a bent pin in the CPU socket could cause the same issue.
The CPU error indicator should appear on the motherboard, not the DRAM light. Since I don’t have other PCs with DDR5 RAM for testing, I’d need to purchase some RAM first to verify if it boots and works properly.
It depends on which part manages the memory controller. If it impacts that area, you might see lights coming from the memory and it could be linked to memory issues. I've experienced something similar before—overclocking an i7-875K caused the memory controller to burn out, though the CPU could still run at normal speeds. Anything beyond that would stop working.
The problem continues even without adjusting the settings, so changing frequency and timing might not help. I'll give it a shot. Also, ran Memtest overnight without any errors. It's unclear if the memory is the problem or the motherboard. I'm considering trying a different brand of RAM to see if that improves things, but I'm not sure it would make a difference.
