As a result of a question in the Excel forum, I'm cross-posting some Memory Testing products. These two are freebies (at your own risk) MemTest86. <A target="_blank" HREF=http://www.qualitas.com/product/ramexam/whatisre.htm>Qualitas' RamExam</A> for USD$24 is from someone I trust . Anyone know of and recommend other/better products?
