are these codes pointing me to cpu or mobo???

This is an error I get when I oc my board past 125fsb no matter the voltage....I have a p4 1.8 that I used to be able to oc to 2.4ghz at 1.65v and 2.52ghz at 1.775v...now I can't do 2.4ghz with even 1.85v using mod trick. Temps are fine...in mid to upper 40's during any of the errors...vcore and 12v look fine no spiking I can see....


I am hoping somebody with some higher end tech experience recognize the addresses as being cpu or mobo....

feel free to pm me with any questions as well...

Semiconductors slow down with time. This aging factor is a square to the voltage applied (even higher if the increased temperature from the higher voltage isn't compensated) and merely directly proportional to temperature. 1.775V is pretty high, and 1.85V is very high. You may be running into aging mechanisms far earlier than expected due to the elevated voltage.

As far as the error, it's hard to know. It's a memory error (invalid page fault) but this could be caused by the memory, the CPU (a bad TLB entry caused by a speed path) or even in the chipset itself (garbling a memory address due to a speed path). It's hard to know without isolating the problem further.

As the local advocate for ECC memory, I feel compelled to add that you'd know if it was a memory error if you had ECC. 🙂
