any temps for amd xp and MSI K7266 pro2 mobo

[anime]

I dont know about that--but the heatsink it was hardly even warm to my hand touch. Opposed to my old regular tbird 1.4 oced to about the same speed. It's was very warm and if I turned off the system-and touch the heatsink again. It will burn my finger. This Xp is not even near that hot. Eventhough my measurement is not accurate--but from my finger telling me-my XP is running very cold at 1.55ghz 😀

Very Cold at 1.55Ghz?

Not even close:

1550@ 1.8V = ~ 74.7W

Tested SK6 C/W = .36C/W

74.7 X .36C/W = ~ 26.9 C over ambient case temp.

That is how hot your "DIE" temp will be over ambietn case temp with an XP@ 1550/1.8V.

With a T-bird, you're looking at:

T-bird @ 1550/1.8V = ~84W. This results in a DIE rise over ambient of: 31 over ambient case temp.


Also, its important to note this: You can't really compare heatsink-temps after shutdown between the two chips. The XP PCB is vastly superior. There isn't much heat held by the PCB, and other parts of the CHIP. With the T-bird, the PCB probably holds a good chunk of the heat, and this is released through the processor die into the heatsink after the shutdown. In terms of actual heat going into the heatsink when running, at the same mhz, a T-bird and AthlonXP are about the same. Its just that there is additional heat release on the t-bird, which, in combination with a HSF that is turned off gets a heatsink very hot.

Mike I think your a smart guy but this is on hands data.
Whyy would my heatsink be warmer tot he touch with my Tbird
but cold with my XP. The temps in the bios are also cooler with
the xp then they were with the tbird. Switching from my old MSI
K7T-Turbo to this one with the same CPU only yeilded a very
small diffrence in temp with the tbird therefore verifing that the
readings are somewhat close. It just doesnt make sense that the
heatsink feels alot cooler but you say its actually hotter.
Isnt the XP supposed to create more heat?

The XP chip is cooler, clock for clock...

When you start overclocking, all bets are off.

You can't trust socket-thermsitors to begin with: Here's hte problem with socket-thermistor Xp chip readings: The New PCB blocks even more heat from hitting the backside thermistor. It renders socket-thermsitor readings far lower than with a t-bird ceramic PCB. Therefore, you cant' directly compare socket-thermistor temps between XP and T-bird chips even on the same motherboard. New PCB, new insulation between socket-thermsitor and CPU.
