XP3200 how many onchip temperature sensors??? w/Gigabyte 7N400-L

[joshcloud9]

I just got an XP3200 (eBay cheap deal! - $95 🙂 to upgrade my XP2400 on a Gigabyte 7N400-L

With the XP2400 the CPU temp was around 40c
upon booting up I went into the BIOS and the reading was 60c and climbing...I almost has a baby!

I took the whole MB out and cleaned all surfaces and did a super micro install of the HSF etc...

I let it boot to Windows and was releieved to see Speedfan showing 44c - perfectly acceptable 4c temp rise I'm thinking...

Then I go into Speedfan setup and see that another sensor (Diode3) has been detected and was reading 60c!

See the pic here: Speedfan/SiSoft Sandra insert

SiSoft Sandra see's the old temp as a Power/Aux temp?

My question is does the XP3200 have two sensors or what am I seeing here...

Thx,
Confused...

CPU temp is commonly the CPU socket temperature. This was where temperature was traditionally read. After the Thunderbirds (or later on, even), AMD included the diode temperature from the CPU. That number is what you should be more concerned about.

Thank you WW,

That makes sense. So at least I know that my 3200 is only running a few degrees hotter than the 2400.
It's settled down to 42c (by the socket method) and 57c bt onchip diode method 🙂

I noticed looking at the AMD specs that the XP3000/400 runs at a similar thermal spec to the XP2400 (ie. over 10% cooler) and is only approx 4% slower than a XP3200
That tends to give the impression that the 3200 is on t he limit of the XP's design ability?

I have an unlocked Mobile XP-2600 Barton on it's way to compare - should be interesting to see which runs hotter!
