I5 2500k temperature question

[almonzore]

ok so this seems really odd to me but maybe someone can shed somelight and give me a explanation.....ok so im OCing my cpu to 4.5ghz and im just about dialed in to about 1.34~1.35v with offset voltage but it seemed when i had my voltage lower i was close to 70C 100% load but now that ive just about got it my temps are barely breaking 63C. so how come my temps got lower with alil higher voltage?








*update*

Ok so i had to bump my vcore up another notch cuz prime95 worker 1 was failing. Its would only make it to test 8 but Im on test 17 and still running strong. My vcore @100% load is 1.4v for 4.5ghz around 70C. Now i know every cpu runs different but i read all these threads of 4.5ghz at like 1.2 or low 1.3ghz. So is my case still considered normal? Do my numbers stillmake sense to any of your more experienced guys out there?

you will be find if fulload 70C ... i think your cpu doesn't ran at 100% everytime, if want more cool try drop voltage if can get stabel or change big and good cpu cooler.
check : in bios setting feature and LLC disabled or enabled don't let auto .. 1.4 for 4.5ghz is too high ,

 

[almonzore]

If drop voltage prime95 worker 1 fails. And one of the fixes was to turn my vcore up and 1.4 is the only voltage i can fond so far that doesn't fail. And i have a huge cooler on my cpu so that isn't the problem. And what feature should i check is disabled or enabled in the bios?



And Im at 1.064~1.072v idle.

 

[henydiah]

no reason for idle
disable turbo boost, EPU Power Save,
VRM: set manual at 350
disable internal PPL overvoltage
Phase Control: Optimize
Duty Control: Extreme
Adaptive Thermal: Enabled
Active Cores: All
Limit Maximum: Disable
Virtualization: Disable
CPU C1E/C3/C6: Enabled if disable C1E, C3/C6 cpu-z will show 4.5ghz everytime

What core voltage should i set it to? Im running a p8p67 deluxe.


And turbo mode auto enabled for anything over 3.3ghz

 

[henydiah]

yes you can setting core voltage by manual and be carefully sterp by step if raise .... try first at 1.26v ( in this voltage my 2500 still boot but fail at test in 45minutes, if your system wont boot clear CMOS) re set again set 1.28 .. till get stable,
or simple away find your oc stable with vcore manual .

Yea 1.26v BSOD me right away. Windows didn't even boot. Gonna goto 1.28v and see what happens.



1.28v BSOD also.


Im up to 1.31v and still BSOD. Windows won't even load.



Ok correction 1.31v actually boots windows to desktop. Gonna run prime95 and see what happens hopefully it doesn't crash.

Prime95 crashed it instantly as soon as i started the test.

 

[henydiah]

don't forget set LLC (load line calibration at ultrahigh / extreme ) good luck

 

[almonzore]

Ok so LLC set to extreme. Cpu current capability set to 140%
vcore at 1.32v and prime95 is actually running. I can only test for a few minutes because i have to leave for work but ill test more tonight when i get home. but in test 7 of worker #1 in prime95 it stopped from a fatal error with some from the hardware. What should i do about this? from what i hear that mean my computer is only running 75% load and to fix it i need to turn up the vcore but that's how i ended up around 1.4v in the first place and that's to high for 4.5ghz .

 

[henydiah]

Cpu current capability set to 100%

 

[almonzore]

Alright ill try that when i get home from work today. But any advice on the prime95 test failing? Only thing i could find was to turn up the vcore?
