Hi,
I recently got a used mz32-AR0 board and running a epyc 7C13 and only have 1 stick of 128gb 2933mz ecc lrdimm in the system at the moment. But on tasks where I should normally be getting a constant cpu utilization it is fluctuating quite a lot.
My motherboard is also missing a capacitor so trying to determine if the capacitor is causing the issues or the ram. I uploaded a image of the missing capacitor if someone has the same motherboard mz32-ar0 and can send a close up image of that capacitor so I can see the values and get a new one that would be great.
Given the fact there’s 2 equal capacitors still left, I’d suggest getting one of those to replace the lost one. Mind, it looks like the old one came off with its pads still attached, so you may not be able to solder the new one to the board.
Thank you for the picture, I think I might refund the mother-board as the component above the capacitor also looks damaged.
I ran occt stress test and with the test running for 14mins i got a HWEA error. I have also ran pass-mark performance test and was getting really bad scores in prime numbers and physics all the rest where normal.
I am currently running prime95.
For all tests it’s using full cpu utilization with no fluctuating
It’s possible that the missing capacitor on your motherboard could be causing the fluctuating CPU utilization. Capacitors play a crucial role in stabilizing power delivery to various components, and their absence can lead to instability.
Here are a few steps you can take:
Check the Missing Capacitor: Identify the location of the missing capacitor and try to get the specifications (capacitance, voltage rating, etc.) for a replacement. If you can find an image of the same motherboard with all components intact, that would be helpful.
Motherboard Manual: Refer to the motherboard manual or manufacturer’s website. They may have detailed schematics that include the specifications for all components.
Contact Manufacturer Support: Reach out to the motherboard manufacturer (Gigabyte) for assistance. They might be able to provide the specifications or a replacement part.
Inspect RAM: Ensure that the RAM is properly seated in its slot. Try running a memory diagnostic tool to check for any issues with the RAM.
Update BIOS/UEFI: Make sure your motherboard’s BIOS/UEFI is up-to-date. Sometimes, updates can resolve stability issues.
Check PSU: Ensure that your power supply unit (PSU) is adequate for your system and is providing stable power.
System Logs: Check system logs for any errors or warnings that might indicate the cause of the instability.
Test with Different Components: If possible, test with a different stick of RAM or another CPU to rule out component-specific issues.
If you can provide the image of the missing capacitor area, I might be able to help you further with identifying it. Otherwise, sharing the images on forums like the Gigabyte forums, Reddit’s r/homelab, or server-related communities could also help you get the necessary information quickly.
It‘s too important to choose the right capacitor. I am currently studying in Shanghai, China. Last week I went to the Shanghai Munich Electronics Show.I collected the top 10 famous capacitor brand in China.
