And on that configuration everything runs great, but when i open a video in bsplayer or in nero showtime my computer freezes. Actually sometimes it does, sometimes it doesn't. But when i watch a video on wmp (i mostly use wmp) everything is normal. I ran orthos for about 5 hours and everything was fine. Then i switched back my cpu to default voltage leaving the other setting as they were while it was overclocked, and now when i watch a movie in bs or in nero everything is fine. What is the problem then??!!! I'm running vista business x64. I also tried different graphics drivers, and tried to unistall audio and video codecs but without any luck. So please if you know something help me!!
P.S. I'm sorry for my bad english. :-)

Your problem is that you switched back to the default CPU voltages. Try running 1.34v.

But processor is running on 1.35v!

Then I don't know.

EDIT: it would appear that you have a bad FSB/Ram ratio... I'd get the ratio closer to 1:1 or 4:3.

lol! I meant that i switched back my cpu to 2.66GHz. And by the way i think if processor works on 3.2GHz and memory works on 800MHz that that is 1:1 ratio, right?

Make sure you have unlinked your RAM. Have you tried with a higher vcore?

[Awesome]

What multiplier does your CPU use? x9?

Reseat your northbridge cooler with Artic Silver 5, and if possible put a cooler on your southbridge. I did this and had to up my northbridge voltage to 1.56v in order to achieve a stable overclock. Also make sure you ram is running on correct voltages. This board tends to not be accurate with all memory.

Try this, it solved my problems and made my overclock increase by 300mhz.

Yes it is unliked. I'll try with higher vcore but i don't know why it works with everything else except when i watch a movie. I was downloading some stuff and PC has been up for almost 3 days (i also played some games) and everything was ok. Even orthos was stable.

multiplier is x8. And i have a cooler on southbridge and a vent over the northbridge. Everest says that temp on a motherboard is 31C.

I know, I put artic silver 5 on my northbridge heatsink and my temps dropped down to 23C at 1.56v given to the northbridge. The problems I was having: I was orthos stable at 1.4v on the northbridge until I tried any 3d application then it would freeze up. I then reseated with artic silver 5, and upped my northbridge to 1.56v which resolved my issue, as well as my temps dropped substantially.

On another note are you using the +100mv option for CPU Vcore in the bios?
