Was just doing some tweaking and testing on my brother's gaming rig, and found something very odd.
He has a AMD 1055t X6 CPU that has been mildly OCed (and undervolted -0.05v) to 3GHz. He uses stock cooler as he doesn't want to spend more $.
I let Prime95 do max temp burn for about an hour and with 21C ambient temp his PC maxed out at 56C. This is a good temp for a 100% burn and 6c under TJmax.
I was also running HWmonitor as Core temp doesn't read X6 temps very well (shows them some 10c cooler than they are) and discovered that the CPU is sucking down 141W during the full burn and idles at 68W with CnQ enabled (cpu rolls down to 800mhz when idle).
He sues a Corsair 550W PSU that has some really good voltages (12v rail is at 12.08!)
For comparison my PC (in my sig) eats up just 119W (stock voltage) and idles at a just 21W (with CnQ).
I am worried about his CPU drawing that much power, His mobo is rated at 140W and according to HWmonitor the CPU is surpassing that. And it idles 3 times higher than mine in wattage consumed.
This is really weird as its a 125W CPU that is actually undervolted....
I am guessing that HWmonitor is not reading the X6 correctly?
dont worry hw monitor gives false wattage reading for some cpus
for example it states that my cpu (phenom II X3 720 be) consumes 99 watts at stock and oc'ed states (stock 2.8; oc'ed 3.5 GHz) whereas its TDP is 95w
[i think some wierd things are happeing with AMD :|]
