Karhu RAM Test is often described as being than HCI Memtest and even 15 times faster in some configurations. Because it uses a highly optimized algorithm that scales well across multiple threads and supports CPU instruction sets like AVX and AVX2, it can saturate your memory subsystem quickly and uncover instabilities that might take hours to appear in other tools.
It needs to allocate large memory pools and bypass standard Windows memory protection mechanisms for accurate testing.
