Then I went through the same process with the other p-states. And kept going like that until I finally reached a voltage (1.05) that was the lowest one it could go without BSODing. So, I started with P0 and cranked it down to the next level, did the BurnIn test, failed but didn't crash, cranked it down another notch, did the BurnIn test, failed but didn't crash.
If I run the BurnIN Test on the defaults it doesn't get a chance to BSOD or fail the test because it shuts off for being too hot. With this the computer doesn't get BSOD during Intel BurnIn but it does fail the BurnIn Test.
I cannot seem to get stable voltages without getting the BSOD.

I have installed the new N-trig drivers (version 2.39), in case this matters. I have an HP tx2-1270 with the RM-75, 2.2 Ghz, 4GB RAM, and 500GB Hard Drive. This means the CPU will raise/drop the DID of Core #0 & #1 together when it detects the one of lowest Core has reached the criteria for a Frequency boost/Throttle Down. This means the CPU will raise/drop the DID of Core #0 & #1 together when it detects the average of both core has reached the criteria for a Frequency boost/Throttle Down.Ĥ:Control clock of all cores together (Criterion is least loaded core). This means the CPU will raise/drop the DID of Core #0 & #1 together when it detects the one of higher Core has reached the criteria for a Frequency boost/Throttle Down.ģ:Control clock of all cores together (Criterion is average of all cores). UnGanged means each CPU Core #0 & #1 operates independently of each other so at any one time their frequency and DID could be different.(This is the original intent of the design of the Turion Chips as they are given different power planes.)Ģ:Control clock of all cores together (Criterion is most loaded core). ClkCtrl:#(0-4) - Enable Clock Control by K10stat (Refer to above). "C:\Program Files\K10stat\K10STAT.exe" -lp:1 -ClkCtrl:2 -StayOnTray -nw StayOnTray - use this option with -nw for Clock Control Mode.(Note after a sleep if the CPU registers are resetted, voltages will revert to default, hence you need -StayOnTray to ensure it is always running in the background)

ClkCtrl:#(0-4) - Enable Clock Control by K10stat.Ģ: Control clock of all cores together (Criterion is most loaded core).ģ: Control clock of all cores together (Criterion is average of all cores).Ĥ: Control clock of all cores together (Criterion is least loaded core).If you set -ClkCtrl:2 you get better performance at the expense of more power consumption.īecause Windows proceed on the assumption that cores are unganged by default.ĪMD K10 Processors were designed originally to use unganged mode to conserve power. The following arguments are available (Source:) It is the time the processor takes to switch from one P-State to the next lower P-State.Īfter you have set suitable values (-0.05 recommended on first try). It is the time the processor takes to switch from one P-State to the next higher P-State. This is the amount of CPU usage load before the processor decrease P-State to meet the minimum load requirements. This is the amount of CPU usage load before the processor increase P-State to meet the minmium load requirements.Ĭurrently it is set at 60% meaning it will switch from P2 to P1 when processor detect 60% CPU load and the same applies from switching from P1 to P0. To set the voltage for P0 simply select P0 and select the corresponding voltage and apply.Ĭaspian CPUs maybe able to run lower than 0.75Vįor me I tested -0.05 is the Max Stable voltage for each default state any higher it BSOD!
