High Apple memory prices may be due, in part, to extensive memory testing at the memory supplier to weed out bad or unreliable memory. Apple may also specify a low die defect level that rules out many memory chips on the wafer. I was once responsible for worldwide memory quality for a major computer manufacturer and we took the same approach.
Memory errors can result from weak or defective bits. A memory error may not matter for photo editing or web browsing but if the computer is used for scientific or precise technical calculations, memory quality is important.
Apple used to offer ECC (error corrected) memory in its most powerful computers. In the absence of ECC memory, I will pay Apple’s higher memory prices every time. I’m paying for quality.
