Damn is my 2800 old? That software doesn't support my cpu.
The first CPUs where this was implemented are Rev D chips, but their value is constant, so its of no interest to us.

BTW, I updated the proggy, and now it also shows CPU Speed and FSBxMultiplier. Use the same link to download it.
 
this is information i got

heres a wild guess...

I think that the MaxTcase temp value represents the highest ambient temp they think the cpu should be able to handle with a regular stock heatsink at stock speeds and voltages. An example of this would be if I built a tank and installed all kinds of GPS navigation equipment inside it and decided to use AMD 64 processors. In the hottest of deserts under most heavy running conditions the compartment where the cpu will be running under reached at maximum 57C while the testing cpu's were in operation. Because of this you would contact AMD and try to make sure that all the cpu's your getting have a maxTcase temp above 57C. That's not the best example but I suppose that it is what those numbers are trying to represent.

Obviously cpu's usually overclock pretty good because AMD wants the processors to be reliable under many conditions, even conditions where the cpu itself is running inside a hot area, so when we overclockers control the conditions we are able to squeeze out more performance. Its really interesting to see these values which probably reflect the results of some kind of test each cpu or samples of each batch are subjected to.

I don't have an absolute max on this chip yet, but it's YBBLE 0524 from ewiz a few weeks back. I primed it for ~7hrs at 1.614 9x280 and could only get about 20 minutes small fft prime with 1.614v 9x290. This chip isn't that great. Seems 55C rated chips don't do so well.

^Great theory!

It seems to me this would be a test of the core/thermal compound/heat spreader assembly, all these are different from CPU to CPU and thus a different max CaseT. i.e AMD tests the CPU after it completely assembled and decides based on the rate of heat transfer across that junction what ambient air with stock cooling is acceptable. So it looks like this is good info, too bad you need it already in your hand to find out. If it is a test of the themal junction it would be interesting to see if the people with lower MaxT's have higher then avg CoreT with whatever cooling they are using(I know this is almost impossible to gauge with the variety of cooling devices and compounds because you would need identical coolin). My CPU for example runs a bit hotter then avg for my type of cooling.

Here is an updated SS for me. This is only at 2.9ghz cuz I am testing some new G.skill 4400 LE's right now.. :p

wait...are you seriously getting almost 3GHz on just 1.3vcore?!?!

[EDIT] oh, right, that just shows defaults. Still, very nice OC! [/EDIT]

No, I wish though. This program only shows default vcore. I am running 1.6v at 2.9ghz adn 2.95ghz.

note that its not 100% stable and that my vcore is 1.5 or so.

That's 67C :drool: @ 1.3v stock, for those who're too lazy to click.
This is the highest rated temp I've seen so far on any rev E chip!!!

Ok I posted a new compilation of stats from both this thread and the one in XS
 
*Place Holder for My 4400+*

2.71 Ghz (Dual Prime Stable so far....)
Will Edit with final results later.
