How much heat is enough for BD?

[Joni]

Where should I stop? I'm now at 4.2 GHz 1.260V. During Prime I get to 63C socket and 48C cores. Should I allow it to go further? So many recommend socket 61C or cores 55C.

Not sure about the socket (use coretemp, make it easy on yourself.. ), but keep the cores under 60C.

According to AMD 61C is maximum operating temperature. They must mean socket since that's how motherboard manufacturers measure it. If I let cores go to 60C then my socket would be over 70C. Wouldn't that be too much on Bulldozer?

What temperatures does AMD overdrive display, socket, core or both?

Found this from somewhere, great info if apply for FX too. I'll be able to push it to 4.6 GHz 24/7

Sorry I didn't get back to you sooner, I just recently had your email forwarded to my department.

Concerning your question regarding the temperatures with your processor. (1090) the maximum temperature threshold is 62 Celsius which set for the internal die (core) temperature of the chip. The core temperatures have an equational offset to determine temperature which equalizes at about 45 Celsius thus giving you more accurate readings at peak temperatures. The hindrance in this is the sub ambient idle temperature readings you speak of.

The silicon and adhesives used in manufacturing these processors has a peak temperature rating of 97+ Celsius before any form of degradation will take place. The processor also has a thermal shut off safe guard in place that shuts the processor down at 90 Celsius.

The Cpu temperature is read form a sensor embedded within the socket of your motherboard causing about a 7-10 Celsius variance form the actual Cpu temperature, which may be what you are reading about on the net.

You can use an application called AMD overdrive, that will allow you to monitor your temperatures accurately.

As long as your core temperature has not exceeded the high side of the 60 degree mark for extended periods of time you should be ok. 62 degrees holds a generous safety net to begin with.

I hope I was able to answer your questions, If you have any more inquiries don't hesitate to contact us.

If you run an ASUS board try to keep the socket reading under 70c. At very most, stretch that to "don't go much over 70c".
If you run Gigabyte, make that number 65c.

CPU cores should be under 60c. Those readings are pretty useless though with BD.

Why is that?

Not sure... not an AMD guy. I just know the only temp you need to know is in Coretemp and the others, to me, just serve to confuse.
