|Nice job with the screencast. I'll get back to you with some o/c settings later.|
"thanks i have Tamkor 2*2GB DDR3 @ 800Mhz . in cpu-z it shows 667Mhz and in task manager it shows 800Mhz"
No, you have DDR3-1066 & it's running at 533MHz @ 1:2 ratio. Exactly how it should be setup when not overclocked.
"i am using stock cooler but i planned to buy hyper TX3 EVO this month"
Save your money. There's no need for an aftermarket cooler.
"i am using inbuilt graphics of g41 chipset X4500"
Apparently you're not a gamer? And if you are, I suggest you use the money you were going to spend on the cooler & invest in a gaming video card.
"my power suppy is of UMAX 450Watts"
Unfortunately, it's low end garbage. Are you from India? Forget what I said about the video card, you need a decent power supply before you can upgrade the graphics.
