Virtual - parity simms work exactly like non - parity memory . they can t tell you when you have a single - bit ram error the way true - parity simms do in a motherboard that implements parity 当记忆体中有一个位元出错时，它们无法像主机板上的真奇偶检验随机存取记忆体那样告诉您有一位元的随机存取记忆体发生错误。
Virtual parity simms can often but not always be distinguished because they only have one more chip than an equivalent non - parity simm , and that one extra chip is smaller than all the others 虚拟奇偶检验simm经常并非总是可以被区分出来，因为它们比非奇偶检验随机存取记忆体多一个晶片，且那片晶片比其他的都要小。
