post #2481 of 3800
so i've been told to check out LLC level 2 as opposed to level 3. here is what i've discovered. 1, it reduces the droop of my core voltage (vdroop I believe) 2. it increases max temps by 2-3c atleast.

How do I know if I need level 2/3 I really need an explanation as I think i'm "high load" stable the only whea error i've gotten in 3 months was from low-load/idle. So does that mean I need to reduce my vdroop IE by using LLC level 2?

I'd guess no because vdroop is when you are at "high load"

I have to up vCore outrageous amounts and it still refuses to be stable. I locked in all the options in "CPU Voltage" options on my board at stock values and I'm using only the offset.
Do I need to increase PLL voltage to get even higher frequencies? That's the only explanation other than I'm at my cooling limit (need to hit the offset 4-5 more times to get 4700 compared to 4600).
don't use offset to find you OC! Use manual and just keep trying untill you can do ibt or prime and the such.

Keep us informed!

what Val says,

and..adjusting PLL is like finding youre stable vcore,
but lowering it a bit can make a oc stable, and get your
temps a bit down, you have to try, some have it as low as 1.5V,
i had 1.65-1.75V most of the time, now its back at 1.8V ..lol

someone did tell me to put it back on 1.8V for higher OC's tho,
but that was when i tried to get 4.8-4.9ghz oc's
you can go over 1.8V, but i dont have experience with that,
have to ask others about it..

What's wrong offset overclocking? It's actually more granular is it not? Implications meaning that you get lower voltages = less heat = higher OC?

I prefer manual over offset for this reason alone.

When you bench or do testings and such you need more vcore to keep it stable while on offset. Hence the offset of so much vcore you need to be stable.

When you use manual you set it and click go. If it doesn't go its not enough. Manual makes it so you have total vcore control all the time at your decisions unlike offset where it changes the vcore itself.

Manual makes OCing and benching much easier than offset because you don't have to deal with the offset amount. Once you find a stable manual vcore THEN you use offset to give it some buffer room incase of a extremely busy spot or something like rendering while gaming.

Manual > Offset, IMO. I hated overclocking on my friend's ASRock Extreme4-M Z77, purely because it has no manual voltage control, only Offset. In my board (with manual voltage control), his 3570K only needed 1.35V to get 4.5GHz, but no matter what we did on his board, Offset kept making the voltage shoot up to ~1.43V under load, and when it was idle, it would jump all over the place.

I'd guess no because vdroop is when you are at "high load"

If you're having instability at idle, you'd want to use less LLC. (In this case, level 3 is lower then level 2)

If you're using offset, try to use lower LLC (Level 5 is lowest, Level 1 highest).
If you're using Fixed, use whatever setting allows you to match your setting in bios with the actual reading in CPU-Z.

Increasing LLC is like increasing voltage at Load. It does not effect idling voltages. Hence, a lot of LLC would mean little voltages at idle and could cause instability.

I encountered this problem in my experiment to overclock via LLC in attempt to achieve super low idling voltages. It was stable at load, but not at idle. Reducing LLC and increasing Vcore accordingly, solved the issue.

Offset fluctuates much more at higher overclocks and becomes increasingly difficult to achieve stability as a result. In most scenarios, Offset is better due to the lower voltages at idle (and hence lower temps), and lower power consumption, however the constant changes in Vcore at load make it less effective in achieving higher overclocks (compared to fixed).

From my experience, the voltage I required at 4.9Ghz was 1.36v for using offset. However, when i used fixed, i only required 1.32v. Offset required extra headroom to make up for the drops in voltages that would occur.
There was also no way I could achieve 5.0Ghz under 1.4V with offset, only fixed vcore worked.

hrm so I might even want to try out LLC level 4? because LLC level 3 was close to the vcore setting in bios but actually like one notch lower in cpu z.

Im using fixed btw.

idk how instable I really am I only got the one low load/idle whea error in 3 months with the 1.285 vcore / llc level 3 so maybe I should just run 1.290 / llc level 3 for awhile??

Yeah. If that's the case, a small bump is voltage should be fine.

I personally wouldn't worry so much if it's just the 1 lone Whea-error over 3 months. =]

I know right, i'm just obsessive compulsive about it and I never wanted to see another one. I have it setup to pop up a box if one occurs and I was actually playing assassins creed 3 on the xbox while on teamspeak with some buddy's and I switched my tv back over to the pc and screamed FACK YOU WHEA!!!

the reason I ask about whea is it was a low load/idle error as all I was doing was talking to someone on teamspeak when it popped.
and yea im hitting 85c now on intel burn test ( never get anywhere near that on anything else) so I don't have much more vcore room to go and I really want 4.5 for the life of this chip.
I know LLC controls vdroop, does my vdroop from what I posted before look right ?

HardwareDecoder my temps at 4.5GHz (1.28 Vcore + iGPU) using IBT were 95C - 98C, after delidding it's under 70C! I hovers in the 60's with only a few quick spikes to 70C.
