I love AMD

[Mekrel]

I know how coretemp works, my point was simply that there's no reason to believe coretemp is deadly accurate. Yes it will tend to be more accurate than what the BIOS is reporting, but at the same time that doesn't mean it's hugely accurate - that's why all the decent review sites use probes.

How can it not be accurate, except if it reads TJunc wrong for Intel processors? Which it has done in the past when the G0's came out. AMD's is a constant formula.

The DTS is actually in die, unless the review sites actually drill into their processors.... The only temperature they could accurately read with a probe would be TCase and that's not the right thing to read.

That's a completely unfair comparrison.

16c was when I switched the machine on for the very first time.

21c is what the motherboard says now, after it's been on for around 3 hours, and Windows has been running etc.

The motherboad only shows the main core temp. So you can't do the 2 reading difference.

21c on the motherboad BIOS reading to 24c on Core Temp software. That's 3c difference.

I was merely pointing out where the difference was calculated. I never said it was a fair comparison or not.

Try this program for stressing http://sp2004.fre3.com/beta/beta2.htm

geekbench doesn't even come close to maxing any of my cores...not sure why

Fair enough. And my point was that your calculation didn't give a true reflection of the situation.

It's realy simple.

BIOS shows 21c. Core Temp shows 24c.

That's 3c difference.

Both readings are from the main core. Both my be wrong or inaccurate. I simply do not know. All I know is that my motherboard isn't faulty. And the original reading of 16c probably wasn't that far off the true temp.

That's with half the memory installed (2GB). Photoshop and 4 instances of Firefox running. And the crappier 8500GT graphics card installed (my 8800GT is coming on Tuesday)

Any good?

And the original reading of 16c probably wasn't that far off the true temp.

...but it was far off. What you don't seem to be understanding is that it's physically impossible for it to be 16c unless your room is freezinarse cold

It wasn't MY calculation. I was only explaining where =C0ld c4Th0d3= got his figures from.

Also coretemp gets its readings directly from the cpu itself (as Mekrel stated above) unlike you motherboard which gets its reading from a probe near to the cpu. Therefore coretemp IS more accurate and your motherboard is quite a way off.

How long does this thing run for m8?

 

[jellybeard999]

NONE of those are accurate

Cheap probes on mobo etc etc... all reading WRONG

It'll be towards 40 degrees tbh

If my car had a speedo that said 70mph, it doesnt mean im going 70mph, with a speedgun or similar, im probably actually going 64mph or so

Okay, so if I stick a fan against my hand for 30 minutes, won't the surface of my hand be colder than the room?

How can it not be accurate

In several different ways. Read the parts of this thread that are pertinent to AMD chips - they go into far more detail than I could bother typing out.

But thats because evaporating water/sweat is transferring heat from your hand. Unfortunately, your heatsink/fan doesnt have this.

Sorry for mixing you up.

3c is not quite a way off.

Understood

Two words - wind chill

Thank you to who ever suggested Core Temp.

I love this little program. It's so handy and nice

Remember the cpu has two cores the second of which was at 29 degrees therefore the difference there is 8 degrees.

Also from your post above you were comparing your original reading of 16 degrees, this is what I was referring to as way off.

No because the motherboard only shows the main core reading.

So you can't say the difference is 8, as you don't know what the motherboard would have said for the second core

Yes but the 16c reading was from the very first time the PC was switched on (no Windows installed).

The 21c reading (much nearer Core Temp) was from when the machine had been on for 3+ hours. That's the reading that should be compared with Core Temp, as they are both from similar circumstances
