I'm not sure if this is normal, but after some stuttering in Far Cry 3 and Hitman Absolution, I decided to check to see if my hard drive was causing issues. I download HD Tune and I didn't like the results. I'm not sure if this is normal, but is the graph suppose to look all over the place like this?
start with the video card..turn off power savings and if your using one monitor make sure you have muilt monitor turned off in nvidia and ati control panel. in windows set to power profile to performance...and not to turn off the hard drive or video card.
in the mb bios turn off c1 and c6 power saving mode. this keep your cpu maxed out.
you got good result all the drive have spike on the test some are more higher then the other this drive does not show any sign of failure.if you want you could the drive maker test tool on short test to feel more safe .
