Hyper Transport Sync Flood Error problem still continues

Last response: in Motherboards

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

First wash it's mouth out with soap!

What voltage is the ram set for (what does the manufacturer say it should be set at)? Since your overclocking you've turned off all power saving features C1E, Coolnquiet.....

"HyperTransport Technology helps reduce the number of buses in a system, which can reduce system bottlenecks and enable today's faster microprocessors to use SYSTEM MEMORY more efficiently in high-end multiprocessor systems".

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.

-EDIT 11/5/2009 9:40pm-

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

Also, my memory voltages are set to AUTO in bios

Best solution

Good, the memory voltage can be a problem if it's too low when the system stresses. Example: motherboard default is 1.8v, according to my modules thats ok with 533mhz and 667mhz but with 800mhz they require 2.1v.

Alright, I turned off cool and quiet in the bios. Also I raised the voltage on the memory to 2.1 volts. My system is very stable ever since I did that. Thanks for your help man. I haven't had one problem with it since I did that. Other than my idle temps on the CPU is about 5 degrees higher, but it's no big deal. Ever since I turned my case fans up to 100% my temps are a hell of alot better, and my 4850 idles at room temp now, instead of 10 degrees over. And my CPU only idles at around 35 degrees Celsious

Hey guys, so im having this problem now as well. It says it was fixed.

What voltage did you raise again with the memory?

The funny thing is is that my memory isnt overclcoked. The only thing that is oc'd is my amd 955be from 3.2 to 4.0 @ 1.4375. My memory is all on auto
