Hi Randy,
You will be very pleased with the Kingston SDRAM chips. I got my Samsung 60GB Hard Drive and the 2 Kingston 256MB SDRAM chips delivered this morning. It took less that 10 minutes to open the covers and stick in the two DIMM chips and slide in the Hard Drive.
Everything is working perfectly.
I am very pleased with Scott and Craig’s recommendations. This was the easiest upgrade. The whole process from ordering through installation was painless.

General Note: Make sure you don’t throw away the small plastic bag containing the 4 Hard Drive screws that came with your Tyros2. The Samsung HD did not come with any mounting screws. You would need to use the ones supplied by Yamaha.
