If revision 2 of the HSDRAM is able to clock higher than the revision 1 stuff I have, then I'll be very impressed. I have revision 1 HSDRAM running at 157.84MHz with 3-2-2 timings. The P3 650 is running at 1025.97MHz and has been looping benchmarks all night without a lockup or error. I'd like to try out the revision 2 HSDRAM and try 157.84MHz with 2-2-2 timings.
