MDD-MAN  I am very grateful for Rember and Memtest, and only want to help improve them.

It would be very nice if the memory test would permit different ranges of memory to be tested sequentially (or by some other algorithm that covers the entire memory range). If this is already done, then, in the immortal words of SNL great Emily LaTella -- never mind!)

Thus before each test a different memory range would be allocated and locked in, which would slow things down a bit. A possible algorithm for 2 GB RAM, where (say) only 1.5 GB can be tested by Rember, would be to do #1-to-#1.5GB on the 1st pass, #1.5GB-to-#2GB and #1-to-#1GB on the 2nd pass, etc.
