見鬼了！我測也是這樣...
RAM：G.SKILL DDR400 512 X 2 <[email protected],Dual 1T>
MB：K8N Diamond (nForce4 SLI)

DDR400 CL2.0-3-3-5 1T.............2079MB/sec
DDR400 CL2.0-3-3-6 1T.............2079MB/sec
DDR400 CL2.0-3-3-7 1T.............2079MB/sec
DDR400 CL2.0-3-3-8 1T.............2143MB/sec
DDR400 CL2.0-3-3-9 1T.............2143MB/sec

但跑DDR480同步或除頻跑DDR410時，調TRAS就都不會變了。
