Since recently purchasing a new 65nm A64 x2, I learnt that there is something about the on-die temperature sensor that makes it read incorrectly in most (all?) current software and BIOSes. Most places suggested that this is because AMD changed the way the temperature is reported, so that a simple software update could fix it. When Abit released BIOS updates for some of their motherboards (not mine yet, unfortunately) that people were reporting fixed the temperature (or at least that it reported a reasonable value, which doesn't necessarily mean the correct value), I concluded that this was indeed the reason for the wrong readings.
However, I came across a post on the CoreTemp forums
that says that the sensor is actually broken. The fact that I have not found any software (CoreTemp, SpeedFan etc) that can read the temperature correctly, even if it both bypasses the BIOS and says it has been patched for Brisbane support, makes me suspicious of what's really going on.
My hope is that either it's not really broken, or if it is broken that the reported value is still a function of temperature and thus could be used to determine the actual temperature.
Does anyone here have any solid information? Has AMD said anything official? I would be a bit miffed if it turns out that I've purchased a broken CPU.
I've bought an Asus M2N-E motherboard and a 65nm Athlon 64 X2 4000+ processor in April. First I couldn't switch on the system, it's reported vga fault through beeps. After 1-2 days of fault cheking I realized that every component working separately, so I had to get an older Athlon 64 to update my boards bios to a newer version because the old one not even capable to boot with a 65nm cpu.
After this completed, I thought everything will work, but this was a mistake.
I inserted the 65nm CPU and the config booted up correctly but after 2 minutes of 100% load the reported core temperature reached 120 degree C, where the motherboard shutted down the system.
The CPU cooler was just warm and it perfectly fitted to the CPU.
I sold the mobo and the cpu and now I'm using an Asrock Conroe865PE (stock P1.2 bios 7/14/2006) mobo which could boot up with a new Core 2 Duo E4400 CPU (manufactured and released in 03/2007) and also handle core temperatures correctly.
