btw - H50 sucks!! "just wanted to vent a little ^^"
I know right? Some guy at Microcenter told me to get it over a Mugen 2 and I told him "you do know that the Mugen 2 gets better load temps and is cheaper too right?"... what a dumba**!

I don't think that max vid means that you can safely run the chip at 1.52v *full load*.

VID is not the same thing as current or load voltage...All the chips were spec'd to be run without LLC.

That brings up something interesting...
If you know for a fact that you are stable at 1.40v load, shouldn't be better to use a high LLC that gives 1.38v idle and 1.40v full load, as opposed to no LLC which is 1.52v BIOS 1.476v idle, 1.40v full load? High idle voltages can't be the best thing for the chip....
Thanks for the bit of info, i saw compudaze saying the same thing actually lol

But my question is, according to my understanding llc is used to eliminate vdrop. Now there is a little flaw in there somewhere because vdrop among mobo's are different. Say you have two mobo's and you set both to 1.52 and llc off will both have load voltage of around 1.4? Could it be that one of those mobos doesn't have that much of a vdrop and setting llc off or on auto and 1.52v it loads it at 1.45? Could that happen?

By the way compudaze did explain running high voltage on load is different from running at idle. Something to do with the amount of amps/wattage. For example ruuning 1.6ghz with 1.5ghz could be below 10amps and running at full load would be over 100amps. So that kinda indicates that degrading shouldn't be present even running on high volts especially when most of the time the current is low.

Forgive me bro i'm still learning, it's like everyday i'm learning something new lol

Loadline (whch is also known as vdroop) is a direct VRD specification by Intel (VRD 12). So all of the motherboards SHOULD droop the voltage by close to the same amount, if they are actually following the VRD specification. Part of that VRD specificiation is the Serial VID that the processor requests, which is calibrated individually per CPU.

If a motherboard is set to 1.52v in BIOS and is giving 1.46 full load, then it's secretly using LLC, and it shoudn't be doing that if it's run according to "specs."

Loadline (vdroop) is a combination of both the cpu vcore, as well as the amount of power it is drawing. Higher vcore+highre power draw (which is basically a direct side effect of higher clock speeds) will cause more vdroop, by design.

These cpu's were not made to be guaranteed 5 ghz stable. That's just luck of the draw and pushing items beyond specification. Loadline calibrations are simply going even further beyond specifications, because vdroop specifically hinders overclocking, unless you are doing conservative overclocks.

back in the old days, there was no such thing as loadline. What you set in the BIOS was what you fed to the CPU. And funnily enough, clock degradation was also much rarer in those days, if you kept the CPU cool. It wasn't until the Pentium 4 and VRD 8.x, which introduced vdroop, that this clock degradation thing really took off. There were some serious reports of P4's failing to be stable at stock, after being subjected to voltages of about 1.7v, after a time, even on high end cooling (default vcore was 1.55v) and these were 120nm-90nm chps, too. Some would even degrade at a VERY conserative 1.65v (this happened to me). And that is **WITHOUT** a vdroop mod! So you're actually getting about 1.60v idle and 1.52v load, BELOW the "1.55v max" rating, and still getting degradation (which was known as GNDS in those days). CPU's which stopped working at stock speeds was SNDS (sudden northwood death syndrome).

Then the core 2 series came, and while degradation was far less serious, it still happened. Happened to my X6800 even when being run at 1.55v (which everyone claimed was safe)--and again this was WITHOUT a vdroop mod!

Bottom line is, none of this stuff happened back in the old days, unless the processors were seeing 90+ degree temps (and I had a 166 mmx @ 262.5 mhz running at 3.3v, on the STOCK heatsink, which saw some light degradation only at that speed...and yet still ran at full 233 mhz stock settings even after that (233 mhz 2.8v). Go figure...
