Massive v Droop

0.188vCore Droop

Nearly five times more droop than Chris

I thought the "droop" was the difference between Idle voltage and Load voltage (0.032V in this case), sorry if I'm mistaken, that's what I meant in my original post.

Enable Voltage Damper/Loadline Calibration and that will remove most (if not all) vDroop

Pencil mod on a board should remove vDrop

Then when u set 1.4volts, you will get 1.4volts whether idle or full load.

Some people are acting like their PC is never idle, vDroop must be slapped because it's making people spend more money on electric bills ££££ and increase their carbon-footprint.
 
Hey don't be sorry Chris it's a discussion about vDroop and hopefully we can all learn something on the subject. Now a lot of people posting on this forum are aiming for big volts and big overclocks, that's how we roll on OcUk and it's the number one obsession here!

Having been an overclocker myself for yonks I am personally bored of just big volts and big MHz but I understand people are having fun, just like I had fun etc

The thing that's changed for me this year is I am becoming aware of life outside of Super-PI and 3Dmark and I have taken up an Eco-Friendly lifestyle, yes I can almost hear somepeople laughing! :D

Anyway my contribution to this thread is an effort to get people to turn down there voltages . . . (ducks the rotten fruit lol!) . . . and I think getting this vDroop thing demystified is a good thing.

Now Jokester has informed us that vDroop is part of the official INTEL spec, I'm not sure If I buy that myself, I mean we are overclockers and we bend the rules, run CPUs and motherboards waaay faster than *Intel spec them, so if we can do that why can't some of us control the voltage as we wish.

MiNxYyY made this thread because he couldn't understand what was going on with the voltages, I had the same thing years ago and I bet a lot of people learning about overclocking all go through the same thought process.

The solution is not to just "Whack Up The vCore!" as has already been stated in this thread it means that once your computer is idle the vDroop will wear off and your running way to many volts through an idle processor.
 
Vdroop is something Intel make them build into the Mobo circuit (not sure on any good reason why apart from they may be scared to overvolt a CPU).

Its not down to a bad Mobo or other issues, all my AMD Asus Mobos overvolts slightly which was good fo OC'ing in the old days.

Without a Circuit like Asus Rog Mobos have to stop it you would need do a Pencil Mod or such.
 
I'm sorry but with all due respect to my fellow forum posters I don't believe anyone actually understands this subject, you may think you do but actually I bet you never really looked into it and are perhaps basing your *knowledge* on hearsay and things some bloke told you.

Now what INTEL want Motherboard manufacturers to do and what companies like ASUS and ABIt actually do are two very different things.

I'm sure INTEL don't want ASUS or ABIT to build motherboards that turn a £200 pound product into a £800 pound product right?

I know full well there are a lot of very technical posters here but I have never seen a good explanation about vDroop from somebody who is knowledgeable on the subject, sorry.

Until someone can explain better why a loaded processor should use less voltage that an idle processor then I stand by my comments in this thread as to the cause and I will continue to experiment :D

The difference in power consumption at idle with and without Vdroop is going to be pretty much insignificant at normal voltages. Only once you crank up the voltages and you increase leakage currents will it make any sort of difference to you.
 
Never heard of 'Loadline Calibration' before (well seen it in the BIOS but never changed it), so changed it from Auto to Enabled.

Going to have a look tonight to see if it makes a difference (E8400 + P35-DS3P).

a bit of vdroop won't be noticable on the bill m8 - someone is completely sucked in by all the media bombardment :)

big business and governments created the mess and as far as i'm concerned they're also responsible for cleaning it up - my conscience is clean :cool:

never seen that option on my gigabyte P35C-DS3R board bios!!! will have to have a look or maybe it's only your model?
 
Its at the bottom of the list on the main OC settings page (where you set multi, mem timings, volts etc) :)

I partially agree with that statement and I know your very technical but at least we agree there is a power saving to be had . . . maybe your not considering that what you describe as an "insignificant power saving" becomes a whole different story when you factor in the 500 million computers users worldwide.

Same answer goes to you marscay, you are thinking about you and yourself, I am thinking a bit bigger.

Aside from saving the world millions of wasted kWh of energy and coming back to smaller matters I do think vDroop is and has always been an undesirable feature/effect/by-product etc, it's never been something useful or a tool for an overclocker.

I no longer suffer from vDroop, I can't 100% say for sure why this is but my best guess is that I have a good PSU/Mobo combo, the net result for me is that I am able to achieve a stable processor frequency of my choosing using less voltage than previously possible.

I am still getting my head around the subject but I think it would be a good thing if everyone else can achieve a stable processor frequency using less voltage and vDroop is not helping, it's not acceptable, lets get rid!

But you've got to balance that against the decreased lifespan of hardware due to the voltage spikes you end up with going from load to idle (at least if you believe Intel) particularly on cheaper motherboards where the power regulation circuitry won't be as high spec. You might be saving pennies, but costing yourself dollars.

PSU has nothing to do with it, you have an Asus board i'm guessing ...same as myself on my main box as i get virtually zero vdroop also.

loadline calibration is the feature that prevents vdroop, nothing to do with the PSU.

they've really got to you haven't they.....think of the millions of watts of energy that is still wasted by corporations around the world and you think you're doing you're bit stopping a tiny bit of vdroop. if you were truly an eco warrior and believe in it so strongly you wouldn't buy pc components for a start knowing where they come from ....that's one particular part of the world that needs cleaning up right now.....keeping them in business buying your hardware makes you look an absolute hypocrit ...no offence :p
 
Looks like it was already running on mine (i.e. Auto = Enabled). I have it set at 1.40 (for 3.6GHz stable) in the BIOS which shows 1.392v in Vista. It stays exactly the same whether idle or full load.

Boots fine at 4GHz @ 1.420v BIOS (1.424v :confused: in Vista) but get Prime95 errors right away on testing. Can't remember what voltage I went up to last time, think it was 1.45 ish which I think is more than enough for a 45nm chip (E8400).

Not sure what is holding it back.. 3.8GHz is almost stable but not fully. 3.6 is spot on but not a great OC from the stock 3GHz really! Was hoping the loadline was the problem.

Also spotted that the memory I have isn't exactly the same. I bought one pair of modules a few months ago which are the same model but are only single sided compared to existing double sided (or vise versa). Not sure if that is it or not as the memory is running 1:1 and isn't at its rated speed of 1066 (running about 800 ish atm).
