Mahmoud are you using RAID 0 or 1 or... ? Forgive me if you've already stated that elsewhere but I'm so busy these days I forget things....not to mention my age-related general deterioration...LOL!!
I got my CPU back up to 3.86ghz yesterday, but then my graphics didn't seem to like it...desktop colours became vivid plus my Media Center TV reception became very jerky, both video and audio. So I reversed it and all is now OK again. Not quite sure why O/C would effect graphics. Not too well versed in such things I'm afraid.
The CPU was also running almost on the upper heat limits all the time with my grid computing projects running in the background (all 6 of them). Now at 3.47ghz it's running in the low 50's Celsius range, both CPU and M/B, which makes me feel better. Not to mention that the fans are quieter too. This case, although acoustically dampened, can get a bit noisy when all 5 fans are blasting at high revs.
By the way, I've added some stock pictures to my album here for you all to see. No point in my taking pictures when the website has the exact same ones already done.
