Voltage too high for 24/7?

post #1 of 22
Thread Starter 
Hi,
I have AMD 955 BE, C2 Revision.

Max rated voltage is 1.5V by AMD, but I have always been reluctant to go past 1.4875 therefore I hit barrier at around 3.75Ghz.

Today, I just had this random feeling to hit 3.8GHz so I am doing right now but 1.512 was a failure.

Now testing at 1.525V. Is this too high for 24/7? Do I need to back off a bit?

Settings right now are
3.8 GHz @ 1.525 V @ 200x19 - 57 Max Temp
2600Mhz CPU/NB @ 1.35V
2000Mhz HT

ps. I know for some people its not that high but being a student frying a cpu is a tall order.

EDIT :
Did 2 hours of p95 and 10 times IBT max with 1.525. Today it just shut down while running 3D mark..
Now at 1.5375

57 max temp, is that idle or underload? If it was under a load for that,how long. I only ask because 57 would make me a little nervous.

With a C2 revision chip you probably aren't going much higher.

Start Prime95 and run at 1.475- it will decrease your temps.

Up to 1.55V is fine, as long as you have decent mosfet's and cooling on your motherboard.
