AMD 955 Temp

[Casdawer]

Just built my PC and booted it up and the motherboard says that the CPU is at 47c already, and that's without having Windows on it or anything.

Do the Phenom II run that hot? Or do i need to change the stock CPU cooler and get some extra 120mm case fans?

Thanks.

What your case like for air flow, fan speed of cpu cooler might need increasing.
Idealy you need to check full load temps.

That's high for a Phenom II - they're all fairly cool running.

Re-seat the heatsink if it's that high at idle - it's not shifting the heat away from the chip.

Just checked again today and it's gone down to 27c which is a hell of a lot better.

I've got the Antec 300 case and i've just bought a side 120mm fan which i'm going to put in later as well as another 2 120mm at the front.

Should keep it cool enough.

I've also noticed that Windows Vista has rated the 955 at 4.7 which can't be right... can it?

What motherboard are you running and what heatsink?
The CPU should get 5.9 in the (rubbish) Vista benchmark...

Throttling with temperatures? Old bios causing trouble?
Mines idles around 31 and goes to mid 40's under load (poor case with no airflow).

Motherboard

I'm using the stock cooler that came with the CPU.

Also, in Task Manager my physical memory is practically gone?!

Your temp drop to 27c now seems to suggest that the thermal paste needed a few hours to bed in etc. I beleive the thermal max for PII as defined by AMD is 62c so keep below 55-60c in any scenario and you will be 'cool'

Also the high memory usage probs has something to do with Vista pagefile, personal experience suggests windows nicks around 25-30% for its own resources and pagefile, even so with 4gb etc as it gets greedy on the pagefile front

CPU-Z results :-

I think something might be wrong here or it might just be me....

Is it on the latest bios?
There are plenty of boards that'll keep the 955 at 800mhz until the bios is updated.

Do you have Cool'n'Quiet enabled ?

as said above u need to disable Cool'n'Quiet in the bios..

 

[Casdawer]

Well i went into the BIOS and found that Cool'n'Quiet was disabled

I've enabled it and now the CPU fluctuates between 800mhz, 2.1Ghz and 3.2Ghz.

 

[Casdawer]

I'm trying to flash the BIOS using my USB stick but the BIOS doesn't see it :/

 

[Casdawer]

Ok - Well i tried to flash the BIOS but no luck, so i left the PC for a while and then went back into the BIOS, disabled CnQ and then restarted the machine....

Now CPU-Z reads at 3.2Ghz constant!

As long as it's not permanently stuck @ 800mhz, I don't see a reason to have C'nQ disabled. It was rubbish on the Phenom 1 but on the PIIs it seems fine, no performance issues.

for stock CnQ is fine enabled but if your overclocking you need to disabled it..

 

[Casdawer]

Overclocking is something i will never do - it's not because i don't know how to do it, but if something goes wrong i'll have to spend £x on replacing whatever blew up.

And the differences between stock and OC arn't THAT different so i can live without an extra 4-10FPS
