Applying thermal paste & dual-core question

[Spawn-Inc]

wow i've been sig quoted... coool!


anyway a pea sized amount seems to much, i heard rice grain (cooked i think) should do it.

this should help

Intersting read (that link)... I'll be sure to redo my As5 at home before Karma goes to her new owner.

Thanks dude +rep

here is the guide for AMD X2's and here is the link in for all processors. You don't use it the same way on all processors - now that is a surprise.

"The example at left shows you an approximate amount to use, about the size of one and a half uncooked grains of short-grain white rice or ¾ of a BB."

I guess 1 1/2 uncooked grains are similar to 1 cooked

About the unequal temps on the 2 cores, I'm there too:

I don't know if it bad or not, but I have the same problem.. It may be the paste, the surfaces not being plane enough or maybe it is just.. this way.. Never wondered, but I'll keep an eye out for more info.. My interpretation: one core is always loaded with the OS stuff, the other.. not.

I think that's partially it but if you look at the OS stuff you can set an affinity for it is usually set to run across both. It might be that some system processes have to run on one core only? Or even that the core "0" is making the decisions as to which core does what?

Interestingly you have the same situation as me: core "0" running a few degrees higher than core "1". Not enough data to support any theories yet but I'd bet this is very common.

When seating a new HSF, wiggle it a little bit before securing the HSF down. It's recommended, but one core being higher than the other isn't uncommon.

Answer: From RightMark - "The independent Open Source Software Project" - forums:

"Dragonforce

I was wondering why my Core2 temp. is 8 degrees lower than my Core1 temp...

Is that normal for Dual-Core CPU's ? AMD Turion X2 here"

"Dmitri Besedin

Yes, it is. At least, it is observed on nearly all AMD CPUs."

They have some interesting looking bits of monitoring software.

the difrence is temps is becuase the 1st core i on the bottom, the heat has to pass through the second core, therefor meaning the second core shows up hotter than the first, or via versa, im not sure if the first is on the top of bottom.

errm.. modern micro technology can't really do that.. every chip made up to now is planar.. it does have interconnections and transistor layered in space, but not 2 on top of each other.. At least, that's what I know So, the cores are side by side, with shared stuff in between or near them.. but planar.. like in the pic:

..which means that if they do have a separate temperature, something is weird.. The cores are very close to each other and in one silicone die.. They should have the same temperature because heat creates a gradient, which would then tend to be equalized by the heat dissipating parts.. Only if there are some really hot "hot spots" on the chips would this weird behavior be explained... or.. I don't know
