System index went down..

[kautilya0]

Hello!
First of all, my config is as follows:
CPU: pentium dual core e5400 @ 2.70ghz, 2.70 ghz
Mobo: gigabyte ga g41m combo
gfx: sapphire radeon hd6670 1gb
hdd: wd caviar green 1tb (EARX)
ram: 4gb ddr3

about a week ago, i ran the windows experience index assessment and it gave the rating "5.9".
7.1 to both aero graphics and gaming graphics
and 5.9 was lowest due to hdd data rate.
i dont exactly remember cpu and ram score, but they were near 6.

I formatted my pc yesterday and today i ran the assessment again. New system rating was "5.4" due to cpu and ram both.
unchanged 7.1 to both gaming and aero.
and unchanged 5.9 to hdd rate.

moreover, when i previously saw "properties" of computer, it showed my processor as "Dual Core E5400 @2.70Ghz, 2.70Ghz.
After formatting, it showed "Dual Core E5400 @2.70Ghz, 2.1GHz.

what is the problem? is my cpu damaged or wht??

You found the issue with windows experience index. It's not reliable - never has been. Don't put a lot of thought to this. If you want to know how your system is running, run some benchmarks.

suggest some good benchmarking softwares then?

okay never mind, there was a voltage problem. The values of voltage and clock speed in my bios were set incorrectly.

One tip, never rely on Windows Experience Index, it is a troll tool made by Micro$oft to make you get the best hardware in the market which costs you a lot of money and then makes you cry as you don't reach 7.9 on each category..

Well i might of gotten a little carried away but you should get the message.

Merry Xmas!
