Commodore 64 Aliexpress 4164 Type RAM: Full Test

Today, the Triple Freedom team embarks on testing memory chips (RAM) sourced from AliExpress to determine their suitability for use in a Commodore 64. The RAM model, MB8264A-15, is nearly identical to the classic 4164 model, offering a 150-nanosecond access speed. The team begins with a tester to ensure the chips pass preliminary checks. However, this initial testing only confirms basic functionality and does not evaluate the chips’ performance under real-world operating conditions.
