What is LLC ?

I was playing Borderlands 3 and after like half hour of playing, the game froze up and restarted the rig.

Went to the bios changed:

Vcore = 1.254V
Vring = 1.15V

Would that be enough ?

I set:

Vcore = 1.258V
Vring = 1.188V

Ran prime95, it worked ok but the temps went really high after several minutes and the frequency dropped. Then I shut prime95 off.

Your overclock is too much. You're hitting the throttling point...

LLC = load line calibration. It is there to reduce/eliminate vdroop. Or, the difference in idle voltage to load voltage. Typically if you set 1.35V in the BIOS, you go into windows with the same voltage (or really close). When you apply a load to the CPU, the voltage can 'droop' significantly. LLC takes that difference and eliminates/reduces it.

LLC is too low. You have to set it higher. Doesn't give enough juice when idling.
No. This is in fact almost the opposite of how it works.

LLC works on load, not idle. At idle it does nothing (unless the LLC is too aggressive and you get what I call 'vraise'). That said, if your llc is too high and overshoots, users core voltage can create too low of voltage on idle.

Also, where did he show signs of vrdoop? I missed it.

What should I do ? Prime95 after couple minutes hit those temps.

What parameters I should modify when OCing my chip ?

I modified the following:
1. Vcore = 1.258V
2. Vring = 1.188V
3. RAMs profile = 1600MHz

LLC = load line calibration. It is there to reduce/eliminate vdroop. Or, the difference in idle voltage to load voltage.

Where to find that in bios settings ? And what valuee should i set it to ?

Typically if you set 1.35V in the BIOS, you go into windows with the same voltage (or really close). When you apply a load to the CPU, the voltage can 'droop' significantly. LLC takes that difference and eliminates/reduces it.

Yeah I know that, the voltage appears when I launch core temp.

Is it like in #22 ? when my clock dropped from 4.2GHz to 3.13GHz because of the very high temperatures ?

The design of LLC is to maintain stability. Vdroop can cause the core voltage to drop below the point where it can support the assigned CPU frequency. No, we're not talking about LLC preventing throttling.

Look in the various bios headings for this setting. Where it is found can differ from manufacture to manufacturer and even board to board in the same company. Some of your settings may be hidden by leaving things on "Auto".

My bad, I mixed up with 1-5 levels on asrock boards (1 being the highest).

I meant exactly what you describe below.

Anyway guys.

My overclock is working OK, no testings with prime95 because of high temps and I couldn't set the right voltages.

Also my gaming with borderlands 3 is ok but not smooth, what to do now ?

Try turning the game detail down. If it runs smoother then the video card is the bottleneck. If it doesn't run smoother then the CPU is the bottleneck. Your system from every angle (GPU, CPU and RAM) has become outdated for more demanding modern games at high detail levels.

I want to squeeze every bit of this rig before upgrading it + it still snappy.

I can do simple stuff; like, buying a water cooling system or a better air cooler.



---------------------------------------------------------------------------------
Update to OCing process:
Now the last restart, I modified the following:
1. Vcore = lower it from 1.275V to 1.25V
2. Vring = raise it from 1.188V to 1.2V

The rig runs smoother than before. What could be the reason ?

I know that there's something about the Vcore and Vring that I need to learn about, the relationship and how they affectt the system. Then I would know why changing anyone would affect any part of the rig.

Until now, everything is ok, no crash or freeze. I'm thinking of running prime95 because I don't want to hit those high temps.

vring is the voltage applied to processor components besides the cores themselves, i.e., the CPU cache and the memory controller. But changing voltage would not affect performance unless by lowering voltage you cause things to run cooler and reduce thermal throttling if indeed that was happening.

You can throw money at better cooling and you might get some minor benefit from it but it will not change the big picture in terms of performance. IMO, you would be smarter to apply that same money to upgrading CPU, motherboard, RAM and maybe GPU. I would hold off on a GPU upgrade until you see how much improvement upgrading the other components would give.

But tell us about your monitor. What is the make and model? If it only has a vertical refresh rate of 60 hz then that could be a performance impediment. What kind of FPS are you getting in your games?

Thanks for telling me about adding my monitor to the sig.

It's a qnix 27", really nice with nice colors. I don't know if it made any problems in terms of speed and refresh rate but I didn't think in that matter a lot. I tried to OC it to 75Hz but I remember I had some color issues so I stopped and then I learned that 60Hz is actually a lot enough for many games.

But I go into intense moments in; for example, BF4, Borderlands 3 ... etc. I don't know if it causing any issues or it's my ping problem I have the ping most the time +110 ms maybe that's why I get killed most the time or I'm a real noob :)

I'm copying a folder that is +100GB from HDD to another HDD.

From Disk 1 to Disk 2, both are HDDs. Disk 0 is the SSD.

Then I tried to launch Borderlands 3, it launches, but it crashes before getting into play mode !

I think the game crashes now because there's a bottleneck somewhere. The HDD I'm launching the game is busy pasting the folder, so I think the HDD don't have enough bandwidth to contain very intense operations, launching a heavy game + pasting a heavy folder. Am I correct here ?

I had to restart the rig to get the game to run, I don't know what is the reason for that but I searched about borderlands 3 crash on startup and it turns it's a known problem. Restarting the rig solved the problem for me.

Update:
I also used disk cleanup to clean anything possible. And it worked so I don't have to restart the rig.

But I didn't know what specifically I have to clean in disk cleanup to fix the issue. But for now things are ok.

Hi,

I started to get constant stutters in Borderlands 3 gaming.

I changed the voltages of the OCing and got some blue screens, my final voltages are:
Vcore = 1.25V
Vring = 1.150V

I launched the game and the same results, the game isn't smooth anymore.

Last night, I reapplied the thermal paste:

20200616_042137.jpg

I have this paste since 2014, could it get down graded ?

Maybe? Buy something new (MX-4 2019) and see... though if temperatures are not out of line, I wouldn't think this has anything to do with the stuttering issue.

That said, that stuff looks THICK and that seems to be A LOT of paste. typically a small BB size covers the IHS of these chips.

Yes, that is one of the more interesting TIM application patterns I have seen. R1S8K you would make a good cake artist.

I returned to the bios and set it back to optimized defaults. The base clock of the 4770k is 3.5GHz but it runs @3.9GHz, I think it's the turbo boost.

So, the game runs absolutely fine and way better than 4.2GHz so obviously my OCing isn't what it should be.

I also think that OCing isn't just about Vcore and Vring, it's also taking care of other parameters.
But I don't have to knowledge and experience to OC a rig.
I would consider to learn about the important parameters that are really important in OCing a CPU.

Yep, how about those patterns :) It's a bit much, but I hope it doesn't affect the heat transfer or something.

Which one ?

Also, do you guys recommend a better cooler than the evo 212 ? I'm planning to buy some stuff to secure the part of OCing that the thermal paste or the cooler are the limitation to get a stable OC ?


-------------------------------------------------------------------------------
I have a concern, could I hurt the CPU when I have done a prime95 test and the temp hit 100 degrees on core 0 ?
