If you even came across a PC system that had a problem with its Ram, there are high chances that you have used PassMark Software MemTest86 software for testing and revealing DRAM errors. The software uses a chain of algorithms, including SIMD and row hammer tests, to try to test if the memory is in a good shape or it has some problems. PC builders have used the software for years to detect and isolate any potential Ram issues that occurred. Today, makers of MemTest86, PassMark Software, previewed initial support for DDR5 memory in their internal software builds. That means that by the time DDR5 memory hits the consumer market, we will have software for testing any possible defective Ram.
