man..by higher tRAS i didnt mean as high as 13-14..i meant near 10.
with very high values..the mem perormance will obviously be degraded.
as about your ram benchmark..i think 6 is too low for the memory you are using. it will obviously perform much better at 8.my system doesnt boot or memtest shows errors if i go above ddr400 at values lower than 7..even though it is corsair..
my everest readings..

as you see,in my case,changing between 2-3-3-7 and 3-3-3-8 doesnt alter performance by much except by decreasing the latency.but i think if i jhad better memory and could boot stably at 6..there woud have been a difference.
but changing it to 2T affects the overall performance in a bad way.

@akshayt..
for disabling ncq go to device manager---->uncollapse the branch for ide controllers---->double click on srial ata controller.
in the dialog box that opens, go to the tab for the channel in which the drive you are disabling ncq for is attached and there uncheck "command queuing".restart your pc.
by disabling ncq..i got decrease in cpu utilization by about 2%, and gains in burst transfer rate, avg transfer rate and access times by about 20mbps, 6mbps and 5 ns resp..
. not much..but shows that disabling ncq helps.
ncq is useful if you are into heavy multitasking..as all it does is intelligently queue concurrent read/write requests considering the disk transfer rate, access times, process priority etc. it is especially useful if you are running a server. but for linear functions like file copy etc or for most of the works in a single user system..it is not of much help.
