Hey thanks guys:D
That's my very first post here at OCforum.
Excellent place here.

Raw memory bandwidth depends on both CPU frequency and memory bus frequency. More exactly, the bandwidth efficiency depends on the memory_divider and the CPU multiplier (the higher the better).

I got my TCCD to run at 350 MHz (HTT 350 MHz), but since the Winchester 3000+ was only at 2.8 GHz on air, so bandwidth obtained was only around 8156 MB/s. As bandwidth efficiency dropped to 73% using a CPU_multiplier of 8 (screen shots (http://www.ocforums.com/showthread.php?p=3467931#post3467931)).

Your CPU was at 3.4 GHz and with a multiplier of x10, even the memory bus frequency is only 342 MHz (8 MHz lower), but the bandwidth achieved got up to 9891 MB/s since efficiency (90%) is much better (CPU multiplier x10 vs x8).

In other runs, CPU between 2.85 GHz, TCCD at 317 MHz, bandwidth obtained was 8192 MB/s.

:welcome: to OCF OPB

Excellent job as normal :attn:

For those that do not know who OPB is...He is one of the top Skill reps...and defintely knows how to fine tune Skills...dam madman when it comes to tuning Skills :attn:

i think OPB knows his RAM...
