A64 Tweaker.

It's a program CodeRed wrote up to tap into the on-chip memory controller on the A64 CPU's. It gives you on-the-fly access to every memory and controller timming and option we know of, in addition to all the ones displayed in the BIOS.

You can set all timings in windows, and those not in your BIOS can be set to load automatically once windows boots.

What does this mean?

Unparralleled memory tweaking for us A64 Users.

With Crucial Ballistix PC4000 Tracer sticks at 261Mhz 1:1 x10CPU x4HTT, I was able to get an extra 400 MB/s write and 150 MB/s read bandwidth in Everest Home just by tightening these in A64 Tweaker:

- Write to Read (Twtr)
- Read to Write Delay (Trtw)
- Row Cycle Time (Trc)
- Row Refresh Cycle Time (Trfc)
- Bypass max

Just some more cool stuff to tweak with, especially for those who like SuperPi and grabbing a few extra points in 3DMark.
