Load Line Calibration (LLC)?

post #1 of 11
Thread Starter 
So I've been digging around and can't find anything about AMD CPUs/boards and this LLC thing. I did some test with three settings for it and got really confused considering what it supposed to do with Intel setups.

I set 1.5volts for my CPU in the BIOS and then:
100% for LLC and ended up with the CPU going all the way down to 1.3 volts during p95 and then BSODing before the first test finished. Max volt occurred at idle and was 1.45

At auto for my board (51%) the CPU went down to 1.41 volts with no BSOD and finished 2 tests before I stopped it. Max volt occurred at idle and was 1.47

At 0% the CPU went up to 1.55(max voltage for the run) under stress and finished four tests before I stopped it. Lowest was at idle of 1.46

So, what the hell is this thing and is it good or bad to have it?

ROFL. Again I get no love. Maybe I should have gone Intel. What's with the AMD side?

First, don't bump your thread 20 minutes after you post.

Now to the answer:
1- Basically Load Line Calibration will prevent those fluctuations from occuring. It is a good thing to turn on.

2- Another thing to note is software voltage readings tend to not be very accurate.

Sorry but the bumping after a day thing didn't work for the last two threads I had.

So, you're saying that it's good yet it caused the most fluctuations? I've heard software isn't that great but can you help me figure out why at 100% I BSOD instantly in p95 and the voltage goes all the way down to 1.3?

Also, should I be worried then about having set my voltage to something in the BIOS that it will never reach because of the LLC?

I responded to this in the other thread you posted in about llc, you can find my response there, as im too lazy to copy and paste it here tongue.gif

Ahhhh yea

Intel = WIN

Sorry AMD guys ..... these are the facts


They are undesputable .....


NO flames intended ..... the question was asked smile.gif

i used to have that board and i found that 19% was a sweet spot for LLC

but otherwise, it's a terrible board in terms of voltage regulation, my vcore was all over the place with & without LLC.. as long as it doesn't spike over 1.55v you should be fine though

But anyway, the question is why is my setup doing this and is there anyone with the same board or any board that's AMD who can do the same or similar test? If my board's screwed up then I want to be able to refund it so getting to the answer is tops to me.

Off topic ish:Why the hell do the makers never give you information on the features you don't know anything about? Don't you think they'd get more customers and bigger profits if they made a guide about overclocking with their board? And since they made it they should know more.

Edit: I'm hitting 1.57 sometimes and I've only set the BIOS voltage to 1.5?! WTH!? So much for getting a good board. frown.gif

Hi! I also have the same problem with the llc, the vcore goes up if I set it to 0% and down at 100%. I have a asus m4a88t-m. and i just want the vcore to be the value in bios and not jump around as much. so any progress on you board?

I built 3 computers using this motherboard, they all had voltage fluctuation regardless of what LLC was set at. Built with a PII X3 740, X4 955, X2 550.

Edit: I have the V version.
