Question White DRAM LED flickers during startup but works normally after shutdown and restart?
Question White DRAM LED flickers during startup but works normally after shutdown and restart?
I've been having this issue where every few days or so, the EZ Debug DRAM LED is shining white and there's no video output, but if I power down and then attempt to boot again, everything boots just fine and there doesn't seem to be any issues when using the computer.
I went through google but I couldn't find anything relating to my exact issue, just people having no boot at all. Hoping this is just an oversight somewhere, but any advice would be appreciated as I'm totally clueless as to how to approach this issue.
PC Specs
MSI MPG Z490 GAMING EDGE WIFI ATX LGA1200 Motherboard
Intel Core i7-10700
GeForce RTX 4060
Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3600 CL18 Memory
Gigabyte P750GM 750 W 80+ Gold Certified Fully Modular ATX Power Supply
Check your BIOS version for the motherboard. Does the problem appear when using a different RAM setup? How do you manage processor cooling in your configuration? What temperatures occur during the issue?
BIOS version: E7C79IMS.1D0
BIOS build date: 08/27/2023
Updating the BIOS feels risky due to past problems with this motherboard.
I don’t have a spare RAM kit.
The cooling setup includes a Corsair H100x and five 120mm case fans.
I can’t confirm the temperatures since the PC doesn’t boot during this process (as noted in my previous post), but I expect typical readings of 30-40°C.
This product isn't a major issue, though it might have been. It seems to be an older problem that was fixed in later models by Gigabyte. The original reports mention high protection settings being lowered, but it’s unclear if the new P750/850GM units are clearly different from the previous ones.
It doesn’t seem directly related to your drive light. Possible causes point to a known issue with Z490 chipset boards and high-performance RAM. Timings might not be ideal for Corsair products, though it could be due to less precise dimmer settings. Fixing this would likely require changing the power supply or selecting a different motherboard.
Some updates to the BIOS might make things worse, as the problem wasn’t fully resolved by manufacturers. It’s worth checking if a BIOS update helps, but it’s not guaranteed. Others suggest that switching to a different motherboard could be a better solution.
It’s possible this is just a minor glitch—don’t worry too much unless you’re willing to spend time learning about memory timings and testing dimming options.
Thanks for the guidance, I plan to switch to a different PSU just to feel more secure. I’ve made sure to update the BIOS as well.
Lots of users report being unable to boot with this motherboard model—it’s strange I can manage.
Do you think it would be an issue keeping this board? The DRAM indicator keeps flashing, appearing almost every day at around 80%. After rebooting and using the PC, nothing seems amiss. I’d prefer to stay with the same board as long as possible, since the data handling is so demanding.
Also, I should note I dropped my PC twice on the floor after posting this and wonder if that might have affected it. Additionally, I’ve noticed unusual noises from my HDD (not just beeping or failure sounds).
Attempt to reinsert the RAM and clean the dimm slots using iso propyl alcohol (system password disabled). This might relate to unstable PSU power delivery or indicate the CPU is having trouble with DDR4 3600MHz. Running a memory test such as TestMem5 with Hi20 or similar tools could provide temporary relief. If errors appear, adjusting timings or lowering the speed to 3200MHz may help. Continued troubleshooting on forums or memory timing guides might be necessary.
