I call BS on whoever takes official informations ad ABSOLUTE LIMITS.

I may not be the best overclocker out therd, but ad far ad I remember those maximum temps were taken straight from the old Phenom II chips.

I may not be IBT Stabile, but what does it Mean? My chip fan well over 79 °C in a couple of testing occasions. Thing is, from my POV very little van happen if you don't keep those temps for a long time.

AMD tells you to use the Tctl, they made the chip, why do you doubt them?

If the Tcase was the IMPORTANT temp here don't ya think AMD would tell you to use that one? if it was also that important the motherboard makers would not be able to get away with arbitrarily changing those values

I am not point on that. You laugh at statement (mine supported by AMD on tCase temp.)

AMD mail clearly said that 61 degrees celsius is maax. tCase temp.

After that you start laughing that is not true.

Can we agree that AMD said that 61 degrees is max tCase for 125w?

Max tctl for all FX is 71 degrees celsius.


I must ask(all) :
When redout on CPU temp is ,lets say 75 degrees, what you think how much is your actual die temperature.
Pure thermodynamics. Please just answer that.


pretty damn close.. there is no sensor.. it is a calculation based on undisclosed factors by AMD

that is what i'm getting at, with their labs and testing sites they would have been able to get this very very accurate. They are the ONLY ones with access to un-soldered Dies, therefore the only ones able to test and figure it out.

its asinine to think otherwise

ive always believed u use socket temp under 50C above that and i follow core/package temp up to 72C

am i wrong?

IME, i've had no issues, not a single one Under 75^ on the socket.

I try to keep my socket no higher then 10^ over core/package

worked out for me since i figured out what sable was for these chips LOL so 1.5 year?

Like you said, 4.5 needs more testing too.
Start with making proper basics...
Changing things from a unstable basis is not the way to go. Too many variables then.

And sure, disabling a few cores help. But you could just as well have bought an 6350 then. tongue.gif

Can you post full info on your 4.5 clock? fsb, multi, cpu-nb, ht, ram and all voltages.
We can then look on where to start bud.

Well, as far as anything past 1.4v I will freeze almost instantly regardless of clockspeed (like 1-2 seconds in to a test). I would worry about getting stable if I could get past that issue first.

Running 4.8 on 4 cores was just a test to see if it was clock related. What was interesting is that I did not insta-freez while on the 1st 4 cores, but as soon as I changed to 1 core per module I was back to insta-freezing. It was speculated that maybe one of the latter cores may have higher leakage, but If that is the case then voltage should solve the issue. And apparently it doesn't.
So it is my belief that the 3rd module is weak. Only way to tell I guess is to put the chip on to a loop. rolleyes.gif

It was also speculated that temp may be the only issue, however I do not believe the chip is hitting 70C in less than 2 seconds (faster than software can report the temp). I fail to see why cores 5-8 would overheat in 1-2 seconds, when cores 1-4 do not. It was speculated that if one of the cores from 5-8 were leaky, then maybe that would explain why those cores temps would skyrocket in comparison to the first 4 cores. But I'm not so sure I can go with that. I never even see 60C before it insta-freezes.


Here is my last test at 4.5 Funny thing is IBT failed. Then I upped the CPU/NB voltage and got better results with IBT, but can't remember how many passes. IBT is new to me, and I sometimes question its reliability. (Sometimes you pass 20 passes, sometimes you don't) Same could be said for any software I guess, if your not actually stable hehe.

Multi only, RAM settings auto.

CPU/NB 2200 1.2v

HTT 2600 1.210v (I believe)

And what if your CPU temp gone over 80 while your core is well inside thermal margin of 71?

What you think which is your actual die temp then?
On which temp silicon degradation starts?

Why you laugh at that post and call it BS when AMD put that out?

Do you really think the people at AMD are no using the concepts of thermodynamic in their equations?? are you really that daft?

if it was that important, AMD wouldn't let Motherboard makers arbitrarily change it. Serious if this was a factor that could burn up the chip to the point of utter damage it wouldn't be allowed

this is why we have HPC mode options in the bios, which if not enabled will throttle when the socket reaches 72^ not quite the 61^ listed...

show me something from AMD about pile-driver and temps and maybe i'll take your word for it, over the guys at AMD when i was at one of their office with my APU. but then again... maybe not.
