MemTest86 9.0 (Build 1000)

Mit Pass­Marks MemTest86 lässt sich mit Hil­fe eines ISO-Images ein boot­ba­rer USB-Stick erstel­len, mit dem der Arbeits­spei­cher von Windows‑, Linux- oder Mac-Sys­te­men auf UEFI-Basis einem Test unter­zo­gen wer­den kann.

MemTest86 ist einer kos­ten­lo­sen sowie einer kos­ten­pflich­ti­gen Pro-Ver­si­on erhält­lich. Es ist nicht zu ver­wech­seln mit Memtest86+ — wel­ches seit 2013 nicht mehr wei­ter­ent­wi­ckelt wird — oder Mem­Test, das unter Win­dows aus­ge­führt wer­den kann.
