G31 not best in OC itink..
u need true power psu.. extreme not true power psu..
what is the default speed?

trying to say i need true power psu to oc? my raidmax non true power can even help me get 4ghz on a quaddie, wat more this cm 500w biggrin.gif

Peace. How you calculate that?

-pWs-
*
the only way ppl can calculate that is by testing themselves, stressing both gpu and cpu and see how much watt the psu was able to deliver continuously smile.gif

@TS, try 300x10, and i dun think u need to change vcore, e5200 should be able to oc to 3ghz with voltage set to auto smile.gif

problem now is with temperature...10x300 will reach like 55~58 degree with prime

ok la tu.... my friend 3.2ghz 1.175v with xigmatek temp less than 55c core temp:).... 55c is not high ok biggrin.gif, or did u mean cpu temp?

Realtemp inaccuracy..based on their article :

TJ Max is an inherently unreliable and inaccurate method of measuring idle/low temperatures. Due to the way it was designed, the readings are so inaccurate under 50C that Intel says they can only be read as a number temperature above 50C. As the temperature approaches TJ Max, the precision increases and at TJ Max the temperature is considered to be 100% accurate..so, try running prime and see your temp..compare between stock and overclock temp at same vcore...
*
TJ Max is the value that activates cpu throttling and auto shuts down the pc when Thermal Monitoring is enabled to prevent overheating of the processor... usually the distance between TJMax is measured and converted into C, lets say distance to tjmax is 50, and the tjmax of this processor is 100c, then the temp is considered 50c...

for youliang's case, he'd just have to adjust the tjmax of the processor smile.gif, and if not mistaken bios only give CPU temp, not CORE temp... coretemp application reads CORE temp, based on the tjmax u set smile.gif... coretemp reads the distance between tjmax and converts to Celsius smile.gif

edit: CPU temp is measured by placing a sensor on the middle of the integrated heatsink of the processor, while CORE temp is measured via digital thermal sensor, placed on each core of the processor smile.gif

the only way to know the temp 100% accurate is to place a sensor directly on the processor itself smile.gif, but reading CORE temp should suffice as they give u an indication when will the throttling activate, and they only activate when the processor is being overheated to its limit smile.gif

so, as long we stay away from tjmax and hv some headroom is ok right?? tjmax for e5200 is 100'c, then if i hv distance from tjmax around 30-40 it save right..
*
of course.. cause when TM activates, it means ur proc is overheated, and of cos thats not good smile.gif
