AthlonXP & temperatures

I understand that the older processors based on the Palomino core ran pretty hot compared to say the latest Thoroughbreds. My question is whether this is true & how is this so?

So for example, would a Palomino based 1700+ processor run warmer than say a Thoroughbred "B" 2000+?


Thanks :) .

I'm not sure, but personally I think Palomino1700+ runs warmer
T-Bred B starts run warmer when it goes to higher Clock speed, how high? then I don't know, if you said 1700+Palomino compared to 2600+ Tbred B, then certainly 2600+ is warmer

Heres my personal experience with both processors mentioned.
I recently upgraded from a 1700 palomino and used a good coolermaster HSF and exhaust fan which was taking air directly out from the side of the heatsink. This was good cooling but the cpu ran 52c idle and 60 full load.

My new cpu is a tbred 2100 overclocked heavily on a high voltage (1.825). The cooling is different but i dont have the exhaust fan, i have an sk7 heatsink. The cpu is running at 2,240mhz, thats over 500mhz over rated speed and idle temp is 46c, full load is 52c. At stock speed which is a more direct comparison it idles at 38c and runs loaded at 42c. Need i say more?

The die on a Palomino CPU is built using the .18 micron process, while Tbred A and B use the .13 micron process. Smaller = less power consumption = less heat produced. Pally's need 1.75 volts to run where a Tbred uses 1.65.

We will see processors from the 0.9 micron process from AMD and Intel soon.

Here's another case. My friend's Palamino 2000+ running at stock speeds of 1667MHz with its stock cooler blazing at 6000rpm runs at 63C at idle and 72C at full load.

My t-bred B 1700+ overclocked to 2137MHz (2700+ speeds) at 1.92V and with the stock HSF spinning at 3000rpm runs at 43C idle and 57C at full load.

Thats a fairly high voltage. How long have you been running it like that as im thinking of trying 1.9v next...

I see, quite interesting.

Ok about these different cores that require different voltages, would say a Thoroughbred "B" processor be able to run on a slightly older motherboard? For example my Asus A7V266-C without problems?

It should only run on 266FSB, I understand that, but what about the voltage? Will it automtically adjust itself, or should I manually set it through the BIOS?


Thanks for the replies :)

My TBreds XP1700+ and XP2000+ run at 1.5V at stock not 1.65V. I think that's why they run much cooler than Palomino.

:smile: Good or Bad have no meaning at all, depends on what your point of view is.

Palomino 2000+ (Stock Voltage) - 39/47C
Tbred B 1700+ (OC to 2000+ and Stock Voltage) - 31/36C

On my MSI 745 Ultra board there is also a HS for the voltage regulators and I notice that with the Tbred these dont warm at all whilst on the Palomino they were hot (around 50C I Guess).

I have been using this new CPU at 1.92 Volts for about 2 months now.

Here's my logic. I bot my first comp about two years back. THen, all i knew about a comp was - it shud have a 17" monitor, a keyboard, a mouse and a rectangular box.
And in these two years i have learnt quite a few things about hardware and then decided to do a complete overhaul. SO if i did my first upgrade in two years, its very likely that my next upgrade will be in less than 2 years, if not more...

OK, coming to the point....if i cud use a CPU for 7-8 years at normal voltage and normal speeds, then mebbe i cud use a CPU for about 3-4 years at higher voltage and higher clock speeds. That still gives me lots of time to upgrade... so i thot i might as well run my CPU at extreme(to the max. limit) speeds and get my money's worth and stay happy :smile:

Thanks for the reply. 1.9 volts it is!

hey, i forgot to mention, i also have a t-bred A 1800+. i used to run that at 1860MHZ at 1.8V. i have the L1 bridges shorted on that. I have that as a spare, just in case.... :smile:
