Hi good day..i want to know if this is normal..i'am trying to oc my old unit which is AMD Phenom II X4 945 in the motherboard MSI 760gm-p21 FX..im using oc genie..max temp reach 255°c then throttle down to 46°c during the torture test i'll link the screenshot..id run this test for 1hour only 0-error 0-warning fromt the prime 95..oh by the way i only oc it to 3.3ghz from stock 3.0 ghz base clock 200mhz x15 to 220 x15 and idont change the dram voltage still 1.5v ..thank you in advance

At 491F your computer would be DEAD. At 100C your BIOS has failsafes(Unless the user disables them) that avoids a thermal death. At 100C(sometimes a bit lower) your PC will automatically shut itself down to prevent hardware damage. Unfortunately some hardware monitors don't understand AMD and the way its sensors work. Use http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/over-drive for an AMD CPU/APU. http://www.tomshardware.com/faq/id-2122665/understanding-temperature-amd-cpus-apus.html can help you make sense of that program. Someone familiar with monitoring programs that always uses an Intel CPU is used to seeing temperatures in a straight forward manner. Overdrive shows Thermal Margins. Takes a minute to get used to.

You also never want to trust a single program. You can use Speedfan, Speccy, Core Temp and MSI Afterburner. If you game this program(Afterburner) applies and overlay to the game so you can see, in real time, as much info as you want. Its OSD is customizable. Speedfan, Speccy, Core Temp can be used to verify temperatures. Overdrive is best for AMD cpus.

Yep, it's an incorrect reading for sure, try a different program.

hi good day aquielisunari, thank you for your reply..iused speccy at the same time with CPUID HWMonitor..when the test 1-5 begin the temp jumps from 46°c to 255°c the slowly throttle down back to 46°c..then passed then test 2 start still the same till test 5 then passed..then a new test start and so on till 65 test in 1hour..thanks again for your reply im going to read the link that you gave..

255 degree Celsius would melt your CPU fan and probably the heatsink mounts so yea, definitely incorrect readings

thank you guys for the reply..by the way im only using this cooler Cooler Master Seidon 120m

The temperature sensor's faulty.

Solder melts at 188 degrees, so 255 degrees will desolder your components from the motherboard.
