Two different temperture read on two programs

[Lm2nlce]

When I use core temp it read 57 to 63 on different cores, Asus Probe tells me its at 45c. Which one is right? And also how do i enable speed step in the bios and do i enable NVIDIA GPU Ex in the bios also???
CPU- Q9550 A stock speeds with stock intel fan.
Motherboard - Asus P5n72-T Premium
Videocard- XFX GeForce GTX 280

I'd go with the coretemp reading as it is generally accepted as being more accurate.

Speedstep should be the options EIST and C1E in your bios (so make sure they are enabled). In XP or vista, set a power scheme of 'portable/laptop' or 'balanced' respectively.

You should be able to check if your CPU is throttling back by downloading and running cpuz. Your CPU core speed will drop down to something like 2Ghz and a multi of 6 if speedstep is working properly.

I'm afraid I don't know anything about the GPU Ex settings.

Oh ok. Well from other programs im gettin a more similar reading from Asus Probe. These are my temps 1.Bios-48-50 2.Core Temp-63-57 3.Asus Probe - 46-47 4.Real Temp 47-50. Does anyone know which temperature i should believe? Core Temp seems ot be the only one giving me the highest reading, way higher as you can see. Im a bit confused???No one would happen to have any knowledge of which programs ?

Ive also noticed that the processor does down clock to 2.6 and when on load it goes back up to 2.8 with speedstep enabled. Is this what your talking about ?

[DMB2000uk]

It looks like coretemp isn't reading the TJunction of the processor right, and so is XX degrees out from all the other programs (which will hopefully be reading it right).

I'd go with the majority reading.

That is sort of speedstep, but I'm pretty sure it should be going further down to 2Ghz when idle, have you left it idling long enough to make sure it isn't doing anything in the background?

Ive only starred at it for a minute or two with side bar running and a few other thing. Maybe i should shut everything off. As for my power profile on windows i have it on high performence. Would this stop speed step from working correctly??? And are these temperatures ok by the way and are they a little high for this cpu?????

[DMB2000uk]

Depends what the CPU is doing, and how hot it is in your room/pc case as to if those temperatures are ok. (If those are load temperatures then they are fine, if they are idle temperatures, once speedstep is working properly and they are still the same, then there could be a problem).

Put the performance settings to balanced (vista) or portable/laptop (xp) and you will see the better power savings of the CPU (while still getting the best performance). As the maximum performance setting could be impacting the speedstep.

Ok. My Idle tempertures on Real Temp range from 43 to 47 mostly being at 45 with speedstep enabled. And on load they sometimes go to high 40s even 50c but somtimes and nothing higher then that.So you still think there could be a problem???? And the room temperatures are at 72 or 73 i would say. Also what do you think would be the correct temperature idle for my cpu on the stock fan?

[DMB2000uk]

Load isn't too high so there is nothing to worry about.

I'm not sure where abouts those processors should idle, my gut instinct says it's a little on the high side, but if it is only clocking back to 2.6Ghz (for whatever reason) then its about what you would expect. Again though it's not too high and is nothing to worry about.

Ok GREAT . Im also going to take a closer look at it with speedstep on and with power setting on balanced. I put the overclocking on manual in the bios and set the cpu to 8.5x which leaves it at stocks speeds @2.80 and that was it. I dont have to leave this stuff on auto for speed step to work right?

[DMB2000uk]

You might have to.

Doesn't hurt to play about with it.

You enable Speedstep in the BIOS. At least, I do...I have an ASUS P5E. It should be under Advanced>CPU Configuration.
