Find out the Max Case Temperature and Max Power draw of your CPU.

[The Coolest]

That is an average TDP for the 3800+ should be a good OCer. But TCaseMax & TDP do not predict OCability but rather more suggest on it, it might be better or worse than other CPU with this rating.

So what do you say about the high TDP.. Here

 

[The Coolest]

That's the highest TDP on these types of chips, again on average these chips run relatively hot at stock but should OC like crazy.
And looking at your overclock its beeing proven

Looks like mine wont be a great OCer but it does run pretty cool

Very interesting program. Thank you

 

[koss20100]

Is that the max this chip will do?

Ive got it stable at 2.7 so far .. i really need to work with my ram which has been giving me trouble. Strange thing it wont prime at 2.75 thou I guess im still pretty new to ocin A64s on a mobo tht makes the most confusing memory settings screen.

so what again constitutes a good ocer? high MTC and TDP?

Update:
I don't know what to make of this (Look at attachment pic)

A lot of people have been getting 49C TCM Opteron lately, some of them were not as good OCers as others, some were pretty damn good overclockers.
The TCM field in a processor is a 4 bit field, and the TCM is calculated like this:
TCM = 49 + (Field * 2)
this means that for 49C the field is 0. This could either signify 49C TCM or a higher than the Max TCM within the thermal profile, which makes more sense.


*EDIT:* I posted about this in AMD's own forum, let's see what answer we can get out of them.

my head hurts now.. thx

I'm with you, confused and confused lol, wheres my jack daniels that will help.

 

[The Coolest]

Basically what AMD said is this:
Any chip with the TCM field set to '0' will not have an actual TCM/TDP rating, as that value has been discarded.
So currently all the "49C TCM" Opterons we've seen actually have unknown TCM/TDP values as of now...

 

[OC Detective]

The Coolest its strange that there is no value assigned yet the Opteron thermal profiles all show the correlation for a TCase Max of 49C to a Power figure.
On the subject of that - can you confirm if the value for power shown in the tables is actually the TDP for that cpu for the given TCasemax rather than the power output under the specific circumstance of when the ambient temperature is 42C. I guess what I am saying is that if the ambient was say 25C for a user can you still say the Power figure shown in the table for the TCasemax you have for your cpu is correct?
Also as there is a shown relationship between TCasemax and TDP do you know which is the independent variable and which is the dependent one? i.e. which one is actually measured to provide information on the other.

Well... What I did is this:
I read the TCaseMax value from the CPU, then check what CPU it is (by BrandID, CPUID and PR rating values), and then match the TCM to a table of TDPs that's correlated to the specific processor.
I can't really confirm what you're asking, but I'm pretty sure that in most cases this figure will be relatively accurate.

I also think that TDP and TCM depend on each other. The higher the TDP, the higher the current leakage, thus the higher TCM the CPU can reach.
