Sorry for the confusion.
First, the numbers you were seeing as Act to Act Delay where on the wrong line of the second table - they should have been on the second line for Rank Write to Read Delay changes. The error must have been my memory acting up - oops except that I wrote it on my other PC while running Memtest on the subject machine.

The first table shows the first changes and lists the entire configuration for each trial. The last column of the first table is the first column of the second table. After the first column in the second table, I entered only the numbers that changed for each trial - I added a header over those - and then I added my final config. Hope that makes it easier to understand.

My current numbers appear reasonably close to the config you listed above - but I thought it was generally the higher end of the numbers and it was reasonable to expect better. My original Memtests appeared to have a single repeating error. My new settings have 5 of 6 settings higher than the original defaults with the changes totalling about 15 clock cycles.

I ran the Sandra benchmarks, but still have not had a chance to learn what they really mean. However I also ran it on my old Dell and compared the numbers for its 3 GB of 667 MHz memory with the new 4 GB of 800 MHz and I thought the new would be comparatively higher. The Dell is the second one -

Benchmark Results
Int Buff'd iSSE2 Memory Bandwidth : 5.91GB/s-------------4.76
Float Buff'd iSSE2 Memory Bandwidth : 5.90GB/s-----------4.73
Results Interpretation : Higher index values are better.

Performance vs. Speed
Int Buff'd iSSE2 Memory Bandwidth : 7.57MB/s/MHz------9.15
Float Buff'd iSSE2 Memory Bandwidth : 7.55MB/s/MHz-------9.11
Results Interpretation : Higher index values are better.

In what order would you suggest I try to reduce my settings from where they are now ?
