overclocking i7 6700k
I own a 6700k overclocked to 4.7ghz at 1.4v with LLC level 5. I aim for 4.8ghz while keeping voltage under 1.45v. I'm seeking guidance on optimal LLC settings (1-7) to balance stable voltage and overvoltage risks. I've tried 4.8 at 1.44 with level 5, which occasionally causes overvoltage to ~1.456 during stress tests but crashes the system after about 20 minutes.
My view on this
Your running stable at 4.7GHz for an hour in Aida64 seems fine.
The Overvolting isn’t too much and doesn’t pose any issues.
Pursuing the extra 100-200MHz isn’t necessary; keep your VCore at 1.376V for better longevity.
Save this profile in Bios, then experiment with recommended settings if you have time and patience. If problems arise, revert to your saved profile.
Discover adaptive voltage and offsets, and set CPU current capability to 120%.
I enjoy experimenting with BIOS parameters and testing CPU and RAM performance, but sometimes you reach a point where no matter what you do, you hit a wall. You can’t go over it, under it, or around it—this is the...
Hi xSimply1337x
I would need to know the MB your using to determine what options you have in Bios. Please list the MB and at the same time, best if you list your full system specs.
I have found LLC (Load Line Calibration) settings best mid range when Overclocking and it can also vary depending on the PSU and also if certain Voltages or offsets set to Auto.
LLC settings are normally increased if it is determined that instability is cause by voltage droop. Also used in conjunction with Current capability to stabilise.
Best is to also take screenies of HWMonitor and AIDA64 at the 10-20 min mark during stress test and post the results for analysis.
You can use IMIGUR to do this. Just upload the images and obtain the BBurl to link to your post.

Recent issue occurred, system froze and crashed after 4 minutes.

Well if it's crashing in AIDA64 after just 4mins then obviously you're not stable.
Best is to clear CMOS back to default and stress test at stock settings.
You need to be stable at stock frequency to establish a baseline for your OC.
If your not stable at stock then no chance with an OC and that needs to be sorted first.

I stated in my OP that I am stable at 4.7 w/ 1.4v
Sorry, but it seems you didn't mention stability in the original post.
Quote: "I have a 6700k overclocked to 4.7ghz at 1.4v with LLC level 5".
Also reviewing your HWMonitor image shows the VCore at 1.472V max, which is too high and leads to excessive core and packet temperatures. At 90°C the CPU would throttle, but I recommend checking AIDA64 during the test at the 10-minute mark, which should be visible on your desktop. Please have them side by side.
This issue is likely causing the crash, possibly due to high VRM temperatures.

Apologies, but it seems you didn't mention stability in your original post. The quote states: "I have a 6700k overclocked to 4.7ghz at 1.4v with LLC level 5". End quote. Also, reviewing your HWMonitor image shows the VCore at 1.472V MAX, which is too high and leads to excessive core and packet temperatures. At 90°C the CPU would throttle, but I need to check AIDA64 during the 10-minute mark, which isn't visible in your picture. Please have both screenshots side by side on your desktop. This issue appears to be the reason for the crash, likely due to VRM temperatures. I bet those VRM readings caused the failure.
Sorry. When I mentioned overclocking, I meant it was stable. I was just testing if I could tweak BIOS settings to reach 4.8 without raising the VCore too much. I'll share images after sleeping with my current 4.7 @ 1.4v running stably in AIDA64.
P.S. Regarding your claim about thermal throttling, I don't think it's related to AIDA64. My CPU only throttles at around 95°C and above, and I haven't exceeded 94°C even with core overvoltages up to 1.456-1.45 as shown in the monitor. Nonetheless, I'll post full screenshots after I sleep.
ok. So a bit of preamble.
When I said it was stable at 1.4v that was true. however I had jumped strait to that from 1.35v when it wasn't stable at 1.35v. I just finished testing all the way down to 1.37v stable with LLC Level 5 (level 4 causes vdroop) 1.36v crashed after 20min.
I am using a Kraken X62 rev. 2 with fans at 100% for testing.
seeing as how 4.7 runs at 1.37v and I couldn't get a stable 4.8 after going all the way to 1.45 I will have to assume that I'm just not going to be able to get that high not only because of temps but putting any more voltage than that through the CPU over time would kill it.
Also, during testing w/ LLC Lvl 5 I don't get vdroop but do get over voltage and it goes back and forth from 1.376 to 1.392 and nowhere in between.
but what is your opinion on the matter?
Here is the screenshot
My view on your setup Your running stable at 4.7GHz for one hour in Aida64 is a good choice and should satisfy you. The Overvolting level isn’t significant and doesn’t pose any issues. Pursuing the extra 100-200MHz isn’t necessary; maintaining the VCore at 1.376V is better for long-term health. Save this configuration in Bios, then experiment with recommended settings from others if you have time and patience. If problems arise, revert to your saved profile. Discover adaptive voltage and offsets, and consider setting CPU current capability to 120%. I enjoy exploring BIOS parameters, testing CPU and RAM performance, but sometimes you reach a point where no matter what you do, you hit a wall. It’s all about luck with the hardware.
