After replacing the motherboard in a Dell laptop due to physical damage, it has the "Other" service tag. The system technically is under regular warranty, but not with this "Other" service tag. Is there a way to change it to match the System?
The dmidecode command will read a Dell service tag, but how can it be changed?
I bought some memory stick which is ovcerclockable. The default frequency is 2.4GHz, the frequency can be configured up to 3.6GHz. And I confiured frequency and the voltage in BIOS, set the frequency to 3.6GHz. Then I ran the memtester86 8.1, to test if overclocking is stable, and it passed all test with no error on 3.6 GHz. Finally, I entery the OS(my OS version is 18.04),and execue sudo dmidecode --type 17 | grep -i speed, it shows like below:
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s

Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
I wonder which is the "actual" frequency of my memory? Did I overclocking success?
And I tried another command, sudo lshw -short -C memory, and it shows this:

It just let me more confusing. Dose overclocking independent with OS? Or I should add some payload to let memory speed up? Can you give me some advice? Thank you!
I bought new memory for my Thinkpad.
Some Windows softwares can tell me the memory's manufacturer and date. Is there any Linux software that can do that?
dmidecode -t memory and lshw -class memory tell me the vendor, product number, serial number. How can I find out manufacture date?
On the motherboard ASUS V-PRO Z77 installed 2x2 (Kingston and Corsair) memory slots. All four slats of RAM do not cause any complaints. They work properly. But, below is the output of the result of running the dmidecode program and in the output I'm interested in the following lines:
Error Information Handle: 0x0060
Error Information Handle: 0x0063
What does it mean?
What are the reasons for these errors?
Unfortunately, I could not find information about this in Google.

What's the meaning of Manufacturer: CE80 in a memory description when listing with command sudo dmidecode -t memory? (Ubuntu 15.10)
