e8400 TDP is 45W instead of 65W

[aeori]

Hi everybody
My first post on this forum

CPU- e8400 (775)
Motherboard - P5G41T-M LX
DDR3, 8GB RAM, Win 7-64Bit Sp1

My e8400 should have 65W TDP, but software (CPU-Z, HWInfo..) shows Max.TDP - 45W.

What is the reason of lower TDP, will it slow my comp or limit its overclocking possibilities?
How can I change (fix) it? BIOS has system default settings.

The reason I looked at cpu-s info is that I want to upgrate CPU to q9650 or alibaba 775 xeon e5450 (they have 80 and 95w TDP) and dont know if my mother/power supply will accept 95W.
Technically, yes (P5G41T-M LX supports about 115W TDP cpu's) but I'm a little worried why my current e8400-s tdp is 45w instead of 64w.

Maybe lower TDP of my processor is because of insufficient power supply? (450w real - never had any problems). Is it possible? Can bad power supply lower CPU-s TDP?

It doesn't matter what's displayed; it still is a 65W TDP CPU. I may be wrong, but it probably isn't reported correctly by the BIOS.

it could think that its a L3110 which is a 45w cpu and has the same specs as the 8400. If its truly a 45w cpu but still runs at all the specs of a 8400 then its putting out less heat which isnt a bad thing.

it is e8400 not Xeon L3110.
Stepping E0. They say, E0 has more overclocking possibilities ... Maybe it has 45w instead of 65w.

It has a 65W TDP and that's what CPU-Z reports on my Asus P5Q Deluxe.

on your cpu-z what does it say under Specification? As you can see in the one below the name is i5 2400 but its actually a E3-1225

I see exactly the same for the CPU, but Max TDP for mine is 65.0 W.
