Brief P45 Bandwidth Testing

[Ket]

Write and Copy bandwidth is far more important than Read bandwidth. Also, Cryptik, shame on you! I can break 9k Read @ a lowly 3.4GHz, you should be able to do much better

CPU frequency has a great influence on write and copy bandwidth, while read bandwidth and latency are more dependent on FSB and RAM frequency.
Just look at my results that I posted some days ago in the Micron D9 club thread, I'm at a lower FSB but same RAM frequency and CL.
Read bandwidth and latency is quite good taking into account all sub-timings were on auto, but I have a very low read and copy bandwidth compared to your scores. zsamz_ said they are very low, but after looking for comparable scores from nVIDIA chipsets I think it's mainly because of my low CPU frequency, and I think the 680i chipset is not that good at write and copy bandwidth ( chipsatz latency maybe ).

Yu got that a bit back-to-front Write and Copy bandwidth are influenced by FSB speed while Read bandwidth is heavily influenced on CPU speed. To see for yourself set something like a 6x multi, then increase FSB until you hit around stock CPU speed, then do a everest test Of course you can't rule out how different chipsets behave, but you should get an idea.
