How do I upgrade my SODIMM memory?
Q1: What should I check before buying SODIMM memory?

A: Confirm your system’s memory type, maximum supported capacity, and slot configuration. You can find this information in the official specifications on the manufacturer’s support page.

Q2: Can I mix different memory modules?

A: Mixing modules from different manufacturers or with different CAS latency and density may cause improper initialization. For best results, use modules with the same part number, manufacturer, and model number.

Q3: Why does my system only show ~3.3 GB of memory when I installed 4 GB or more?

A: Some 32-bit operating systems have addressing limits. Even if your hardware supports ≥4 GB, the OS may only utilize about 3.3 GB.

Q4: How do I safely install new SODIMM memory?

A:
1. Power off the system and unplug the AC power.
2. Discharge static electricity with ESD protection.
3. Remove the original module by unlocking the latches and pulling it out at a 45° angle.
4. Insert the new SODIMM(s), align with the notch, and press down until secured.
5. Power on the system — the firmware will auto-detect the new memory without BIOS changes.
Q5: What should I do if my system doesn’t boot after installation?

A: Re-seat the modules and check that they are properly aligned in the slots. This often resolves boot issues.

Q6: Any additional tips for the best performance?

A: Always install SODIMMs in identical pairs (same capacity, speed, and specification) for stable operation and optimal performance.
Why does the system detect only half of the memory installed?

Some older version motherboards do not support new memory. Therefore the system cannot detect correct memory capacity.
Why does my memory fail the Norton memory test?

The Norton memory test program will fail when system memory is over 256MB.
Which one is better? CAS latency=2 or CAS latency=3?

CAS latency =2 means that the data access is one cycle faster than CAS 3. Therefore CAS 2 is better.
How do I know the exact capacity?

The capacity is shown in "Megabyte" (same with Hard Disk Drive, 1MB = 1000KB). In Windows environment or DOS mode, 1MB equals to 1024 KB. Therefore 1GB is approximate 953MB.
The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file format and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.
