My above system was running fine as i tested them rigourously with Prime 95 & Memtest to which all it passed.

Issue: I recently upgraded from an OEM Edition of W7 Ultimate 64 Bit to Windows 7 Ultimate Retail 64 Bit Build: 6.1.7600. After this i noticed My ATI 5850 Graphic card score went down to 6.0 from 7.7. I was utterly frustrated at this did the following steps to rectify but in vain.

Tried installing & reinstalling all the known Drives from the ATI's website including the current 10.2

went here: C:\windows\Performance\WinSAT\DataStore, And deleted contents of Datastore folder. went back & re run it but no go :-(


Did a clean install of Windows iteself and checked with the same set of drivers
The Case & CPU IDLE Temps are less than 40 Deg C and on full loat it doesnt go beyond 52 Deg C.

Tried System Restore as well many times and that at one point of time i got 3 BSOD's while reinstalling the ATI 8.66 Display Driver.

I am out of any known ideas and hence require your able guidance to get me back my 7.7 Rating of my Exp ATI 5850.

I know that the WEI is not that big of an indicator but still i had that rating before and it hurts if its 6.0 now.

Awaiting Impatiently for your solution/s

It's something to do with these later ATI drivers. Seen quite a few mentioning it going to 6.0, including it happening to me a few times.

Go here: C:\windows\Performance\WinSAT\DataStore

And delete what's in that Datastore folder. Go back and re run it.

Control Panel-Performance Info and Tools-Advanced Tools (on left side) -first option. I can run it one time and it will give me 6.0, then turn the fan up on my card or something, re run it again, and it will give the right score again.

just go here. This is supposed to clear the previous scores, then re run it.




Might reboot, then try and re run it again. Like I said, I 'm not 100% it's ATI's drivers, but since 9.12 onwards, it's done it to me, and usually turning up the fan on my card and re running it gets it back to the right score. Never saw it happen before 9.12 drivers.
