LLC: Idle voltage < Load voltage - Is that bad?

post #1 of 3
Thread Starter 
Greetings,

Though I've been overclocking for a while I never paid much attention to Load Line Calibration. Someone told me to enable it and I left it at that. But today I found out there is (or was) quite some debate on whether LLC was actually good for you or not. What I've been able to gather is that if your idle voltage is higher than your load voltage, you should be good. But according to CPU-Z that's not the case with me.

I run my Q9650 at 3.8ghz with the cpu voltage set to 1.225v in the bios.
With speedstep and C1E disabled Cpu-Z tells me my Vcore is at 1.200v when idle. If I fire up LinX (max stress) this jumps to 1.216v under load.

I tried disabling LLC but I was greeted with a bsod upon attempting to boot.

Any thoughts or clarification would be much appreciated.

I don't like LLC... I've heard of it harming chips etc...

I believe what it does is just pump in more juice when it senses the CPU is under load...

I just go the old fashioned way, if it needs more volts give it more volts. This way, the hardware isn't doing what it 'thinks' is right. (hardware isn't very smart sometimes)

Well I got to 3.8ghz without using LLC. Quite a difference in voltage.
With LLC enabled 1.225v in bios was enough. Without llc I have to push the voltage up to 1.32 in bios, which becomes 1.27 after Vdrop when idle. and about 1.21v after Vdroop under full load. Fortunately temps haven't changed.
