Should I put the LLC to 70% ?

Put LLC to 75%, you have a 70% option?

With a stress test on prim95, like always.

Yeah sorry it's 75%.


So I did it and now my vCore is between 1.344-1.352 under load, my manual vCore is 1.336 so it should be stable.

But is it possible to get closer to my manual vCore by switching back the LLC to 50% and increasing my offset ?

offset most of the time will give you a bit higher voltage then using fixed vcore,
when you lower your llc, you need more offset to compensate for the vdroop as i understand it,
last week i did some testing with offset and llc.. with no vdroop, the offset will overshoot the voltage,
but it worked for me on my mobo..

llc turbo, thats about the same as your 75% setting


llc extreme, no vdroop

best is to have a bit vdroop when using offset

VonDutch,

Does that article still have relevance since the charts are over 5 years old?
They seem to be saying you should set LLC to 0%. If you do that your, vCore can spike to way higher than it would at LLC 75%, so I don't understand what they are saying.

If I know I need around 1.28v to be stable at 4.6, then I can use manual 1.28v and LLC at 75%. It works fine and my vCore can go up about .01 more for a max of approximately1.29v. If I switch to offset mode then the same 1.29v observed max is still seen but the vCore can drop when idle. Again no problem there.

Per the Masterlair article, he says to put LLC to 0%. That means you have to raise your offset a lot, and I do mean a lot, in order to have your vCore under load get up to the 1.28 to 1.29 that I know I need. That means the vCore has the ability to spike significantly higher (while idle anyway, but a spike is still a spike) than if I leave LLC at 75%. Which seems to be the opposite of what he is saying.

What am I missing?

i think its still relevant in the way, it shows how vdroop works smile.gif
and how its used with offset, you want a bit vdroop if you use offset,
if you set it to 0% or with mine to Extreme, it will(prolly) overshoot the voltage thats set
as you can see in the first chart smile.gif but with me it wasnt that much, depends on your mobo too i guess
im using a gigabyte mobo, so the settings are called different on Asus mobo's,
i think 75% is about the same as my Turbo setting..

in Sin0822's guide he says,

If you want the best results you should disable power saving options like I have below,
however if you want the CPU frequency to drop under idle conditions, you should leave them enabled.
You should also leave them enabled if you will use DVID Voltage offset instead of fixed voltage.

You will also want to set LLC which is under the 3D power menu,
the LLC should be set to Turbo for a slight droop, or Extreme for no droop at all.
I recommend a slight drop of voltage under load, this might help with temperatures.

Load Line Calibration:
This setting can be increased in intensity which will decrease the standard Vdroop setting for the voltages,
the CPU VCore LLC is the most important, and if you are OCing on air you should set Turbo and if on LN2 you should set Extreme.


im not that technical, maybe others here can explain this better then me biggrin.gif
took me a while to understand how it works, i only use offset with my oc's,
only not with very high oc's, i dont like very high offset's,
like for 4.8ghz, i needed 0.160V offset, which i found (personally) to much,
but 0.55 or 0.35ish, like the above examples i used, works very well for me

maybe the original anandtech post , where they took it from, explains is better,
http://www.anandtech.com/show/2404/5
thats the one ive read at first,
the other one i found later, when i was searching for something about offset etc,
youre right its a bit more confusing maybe..sorry smile.gif

Hey guys! I finally got my Overclock Stable! No errors no BSOD no Stop workers and importantly NO WHEA or Event errors!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Manual Vcore set @ 1.340 at 4.4Ghz. VID is at 1.3160 = Off set at +0.025 - I assume my OC is stable???

Temps reached 89C at one point but most of the time its under 70C. I know VCORE is high for this clock, but I think I really got unlucky with this chip.

The device manager errors in logs was when I reformatted my computer. I ran the test yesterday till just now. And no errors whats so ever.

Note: Memtest86 also passed 12hour mark with no errors (5 passes)

Please confirm that I'm good to go and just enjoy my computer!!!!



Edit: Off set at +0.025

I hope you mean offset is .02 not .2 as you wrote.

With setting an offset you have to round, and we all know that .005 one way or the other can make or break stability. I would recommend picking a time where it is convenient to run the testing for 18 hours with your offset in before assuming everything is perfect, but that is just me.

I agree with you.

But apart from that Hamm - you are good to go smile.gif
