Tdp?

[hat]

I need to know how to find out what my TDP is... anyone got the formula?

[btarunr]

TDP = Thermal Design Point. It's how much heat your cooler has to dissipate to keep your CPU running. I'm working out your TPU and what your cooler should look like. Watch this space. Will work this out this evening. Is that a Windsor or a Brisbane you've got?

How? And you don't know what voltage I'm running at.

[btarunr]

I'm assuming you're doing stock-volts using a Windsor 95W.

1.325v at 2750mhz 2x1mb cache Windsor
How do you do work it out?

[btarunr]

For Windsor, 0.005v increase steps up TDP by 3.03 W, At stock volts, Increase in 10 MHz causes it to rise by 1.650 W

But I don't even know my TDP in the first place!

[btarunr]

At stock everything, your chip does 95W. There's also a rare 120W variant. Use Everest Home Edition and tell me its wattage. Everest > Motherboard > CPU > CPU Physical Info

There's a CPU and a CPUID, and under niether of the tabs does it say anything about "physical info".

In any case, I'll be getting an AC Freezer 64 Pro soon, and heat shouldn't be much of an object for me anymore. As well as the noise from the CPU cooler (woohoo, I can complain about that now, not my power supply)

damn my 51.2dBA case fan, I want to do the 7v mod to it, it's not designed to be used with a fan controller

Took this screen off one of my comps.

You can find thing under Motherboard > CPU

3.03? How can you be so accurate on TDP increase when the clockspeed isn't even mentioned. ie increasing the voltage by 0.005v at 2GHz would raise the TDP less than doing it at 3GHz. Besides, TDP isn't even exact, how could it be calculated with 2 decimals in any circumstance?


Where are you getting these numbers from?

[btarunr]

The accuracy into decimal points are derived from the software used to monitor voltages such as Everest Ultimate. I just derived an equation based on that. I never did any research on this as such nor did look up information from any other forum or website, just that by observing these values when OC'ing my old Windsor 5400+ which had a stock-clock of 2.80 GHz.

I got 91 watts MAX. This is from the extreme power supply calculator. Remember, this is max because the maximum heat generated can not exceed the amount of energy inputed. Now thing is idk if I selected the right cpu, that's the non-ee one (91 watts). Oh and according to the calculator you undervolted it to overclock it? Stock volts-1.35? speed-2600 mhz? (sorry I'm horrible with amd chips)
