After replacing the factory installed 2×12Gb memory modules with 2×32Gb Crucial p/n CT32G56C46S5.M16B2, the computer freezes at the moment of loading the bios during a “cold” start. Loading occurs from the second or third atempt. After loading - no problems. I checked the memory in various tests. Fastboot works without problems - until the power is turned off. I tried resetting the bios, without result. With factory modules - works properly. model info: 8B.023600835N10 SN:B87455DH30180 SER8-L-241TBVK0W64PRO-DP/XA bios ver: HPT.8xxx.SER8.V029.P8C0M OC15.12.Link

Kron We recommend that you try updating your BIOS. Please provide a screenshot of your main BIOS page (Please repeatedly press delete key as soon as you turn on the PC, go to BIOS.) and we will provide you with the correct link and tutorial.

I updated the BIOS version to the latest one available on the site. I entered all the memory data manually and disabled memory training, but there is no result - the system cannot reboot, only after 2-5 times I pressed the power button when the power indicator is on, but the screen remains black. After booting, the system is rockstable.

Kron When you say the system is stable do you mean that the machine is running fine now?

support6 After loading - it works fine, but it cannot reboot or turn on normally with new memory installed.

Kron Here are some steps you can try to troubleshoot the problem: 1.Check the power supply: Make sure that the power cable is securely connected to the power source and the PC. 2.Press and hold the power button: Sometimes, the PC may not respond to a normal restart command. Try pressing and holding the power button for at least 10 seconds until the PC shuts down completely. Then, wait a few seconds and press the power button again to turn it back on. 3.Check hardware connections: Ensure that all cables and connections inside the PC are secure, including the power cables, RAM modules. 4.Clear CMOS: Please turn off the PC , unplug the power supply, and press the CMOS button (if no CMOS button, please put the pin in the CMOS pinhole and press it ) for about 10 seconds , restart the PC after ten minutes. Here is the tutorial https://mega.nz/file/XypwTISY#DVT0BsjOgiPkZ-drQaj88JH9Z7f7qpKGP2E3nMHW8ms 5.Boot into safe mode: If your PC is experiencing issues during the startup process, try booting into safe mode. This allows you to load the basic drivers and bypass any potential software conflicts. From there, you can troubleshoot and identify the root cause of the problem.

I tried all of the above. With different memory modules, and in two different Ser 8 mini PCs with different BIOS - everything goes wrong when using the CT32G56C46S5.M16B2 module (2025, Micron chips) - one or a pair does not matter. I think this is a hardware compatibility issue. similar behavior is also present on factory devices - exactly as I describe, you can read about it at the link [ These modules do not behave like this in other systems. Your team can check this issue themselves. Best regards

Kron Please try to update your graphics card driver: Link: https://url.bee-link.cn/1M4S Tutorial: https://buildin.ai/50c2dee7-dcde-4707-97d8-dc7eac84a4eb

the PC does not start from the off state, does not reboot from Linux and even from installation USB drives, and you suggest updating the video card drivers :) ?

Kron Hi there Will this issue happen if you use original RAMs? could you send us pics on both sides of the new RAMs?

SER-8 Problem to boot after memory upgrade

Kron

With original modules it works properly. Now I installed a 64Gb kit from Kingston KF556S40IBK2-64 and it works flawlessly! Sending photo of the modules with which it does not start, the modules have been tested by Memtest, Cinebenh, and other (using SER 8 and Lenovo notebook), in other systems they do not cause any problems with startup.

Please update the BIOS . i sent you pm
May i know if you use only one of these RAMs in the pictures . will it work ?

Grimani

support4 can you send me the new bios to try?

Kron

Tried both and one with the same effect. Since the problem with the Kingston modules has disappeared, I will hold off on updating the BIOS for now plus I have the latest version, as I wrote above.

Thanks for your reply.
If you have any questions during the use of the machine, please feel free to contact us. Have a nice day!

Grimani

I have same issue I think - using same Micron memory (1×32GB)

I haven’t gotten it to start at all except once and since then the fan doesn’t even start.

When you say “cold” boot doesn’t work but after 2-5 times it works - is “cold” boot plugging in the power? 2-5 times of pressing the power button 10 seconds to turn off and on again?

Grimani

changed to a kingston module and now it works …

Thanks for your feedback.

Please send us a picture of SN number and BIOS version.
So we would be able to know whether it is latest BIOS and send you files accordingly.
Here`s how to check your BIOS version:https://mega.nz/#F!yuISGa4I!s1bQQajKwnsEdzjqq4nopQ

Your machine’s BIOS is already up to date and does not need to be updated.

Grimani

Perhaps, but your BIOS is still incompatible with Micron 32GB DRAM….

Hello there，

Yes, perhaps there is a compatibility issue between the brand of the machine and the RAM.

If you have any questions during the use of the machine, please feel free to contact us.

Have a nice day!

Grimani

Isn’t this something you’d want to solve…?

Grimani
Hi there
May i know if you have tried other RAM brands?

Grimani

As I said, Kingston works fine. MIcron does not. Tried on two SER8s

Grimani

Hello there,

The issue of brand compatibility is temporarily unsolvable.

We will contact the R&D personnel to conduct more tests in the future and try to minimize the compatibility issues between the machine and the RAM brand.

Have a nice day!
