[Solved] Hyper Transport Sync Flood Error problem still continues

About a month after i built a computer, it started to restart when playing graphic intensive games. After only about 15 minutes of playing it freezes, then restarts saying "hyper transport sync flood error" press F1 to continue.

Ive read posts on here about it and people have been saying Asus is famous for this error. They just said update the bios and everything will be fine. Well last night i updated my bios from 1104 to 1708. And everything was great, until tonight. I was playing Call of Duty: Modern Warfare 2 online, and it froze, and shut off giving me the same error. What can i do, should i buy a new mobo? I checked my temps, and nothing to high, they were actually very low.




My system
-AMD PII 720 OC'd @3.0GHz (i tried under-clocking to as low as 2.5GHz, but the error still came up)
-ASUS M4A78-E mobo
-Antec P182 case with stock case fans on rear, turned up all the way
-4GB DDR2 800MHz memory
-1TB HD, 160GB HD w/ Widnows 7 ultimate 64-bit
-ATI 4850 1GB
-Sigma Monster 750W psu

You know, i never turned off CoolNquiet, thats probably what keeps giving me the error, ill turn that off, and check all my voltages and settings.

I turned off cool and quiet, now my cpuID reads 2.8GHz instead of 800MHz like before, and now ill go ahead and check out my multiplier for my cores. Another new thing that came up since i updated the bios is "unleashing mode". I enabled it, and my 720BE reads as having 4 cores in CPU-ID, so i guess its another way of unlocking the 4th core on the 720s? anyway, i havent left it enabled. Since i havent tested it in prime95 to make sure the 4th core is stable
