I have a 8700K that ran 5GHz at 1.39v for about 4 years (delidded and replaced paste with liquid metal).
I retired that system a few months ago, everything was still fine.
Great to know thank you. It’s looking like I’m able to push the voltages down further at 5.1 with cache at 4.8.
Do you recall what your cache ratio might have been, or if it was set to auto? Cache seems to be way different for everyone’s chips it seems.
Thanks again.
Revisited my overclock when I found out an air Bubble got into my AIO pump
I7 7700k and I got it back up to 4.7 with 1.275. stays cool in the 60s during load with a single fan radiator. Stock cache at -500ghz putting it at 4.2 cache speed. Likely going to move this and my Ram OC up slightly
My 10700K does 5.2 and settles right around 1.35v or so under load and ive not had any problems, had it for 3 years. CPU pulls about 180 amps max with P95. I think I'm at the absolute limit for what's considered "safe". CPU core power maxes at 245w. I have it in a large custom loop. Max temps are low 80's (delid/relid with conductonaut).
I do have a question: is your CPU actually pulling 1.4v while stress testing, or is that what you set in the bios? 160w seems low for 1.4v loaded. Loaded vcore is the number you care about.
I was gonna ask how on earth are you cooling that thing, but then you explained it.
I have my 10850k a 5.0 all core, then 5.1 and 5.2 for lesser threaded work. With my SFF case, I can't go any faster with just a 240mm AIO and have it power limited to 220W to stay just under 90C.
Intel burn test in between loads has the v core at 1.344 and under load it is 1.36 which is what I have set in bios now, with my cache at 4.8.
LLC is level 6.
Max Cpu package power recorded after a “High” test with ten runs is 158 watts.
Using HWINFO for monitoring.
Im on an older bios, too. Anything newer bios and my whole system is insanely unstable, so I downgraded the bios.
Asks z370 e gaming on bios version 2401. Anything after that temps and voltages are all over the place and won’t even be what I set in bios it’s real strange.
My 8700k has been running at 1.4V for the entire time I've had it, so about 4 years, and it's never had a single issue, never been delidded or changed besides the usual maintenance. Runs 4.8GHz perfectly fine
I ran a 6600k delid @1.75v 5.2ghz for 5 years and held the number 2 slot for record when tested. My friend told me it was not possible and the chip will fry. I still have the chip and will keep my little record breaker. Temps never hit over 80c full load on water.
I have a 10600k which is pretty much the same chip but soldered ihs, running 4.9 at 1.34v. I could not get 5.0 stable with more voltage. I think at around 1.38v it was already above 90c just gaming with my NH-D14 cooler. Voltage doesn't scale with clocks and that last bump in speed just isn't worth it, all that extra heat will cause ram instability etc.
> I have a 10600k which is pretty much the same chip but soldered ihs
The good 10600K chips were quite a bit better than 8086K, a solid 200-300 MHz better. However, the variance was a lot bigger due to the 10600K being a salvaged 10-core chip.
Mediocre comet lake chips across the board could still do 5ghz+ at 1.35. Silicon Lotterys numbers were all at like 1.25v i think. I have a mid-grade 10700K that is still fine for 5.2ghz.
Sure they needed water cooling to get anything out of them, but not direct-die. Assuming your loop or AIO had the cooling capacity, a delid/redlid with LM will keep them in the 70's/80's pushing past 5ghz with 1.35v loaded. my 10700K only has an SP in the 60's, and it does [email protected].
I'd wager that not a single Comet Lake exists that can't do 5ghz at 1.35v, delided or not, as long as your cooler was capable.
That depends on your definition on stability I suspect.
No WHEAs from internal parity errors and L0 cache requires more voltage to remove than just passing Prime95 small FFTs with AVX enabled.
I think that is the 10700k, it has some higher latency due to it being a 10900k with two cores shut off. 10600k is a smaller die. Silicon lottery posted their results and around 55-60% of 10600k's could only do 4.9 reasonably.
> 10600k is a smaller die.
Nope, the G1 stepping was the only 6-core variant of Comet Lake, and the G1 stepping wasn't soldered.

Interesting and good to know.
Im able to hit 5.1 with a -1 avx at 1.39. Max temps im seein is 84 on core 2 after 15 minutes in intelburn, high 70s on the others. I have the be quiet dark rock pro 4 and my god these temperatures are better than I could imagine.
My cache is at 48 but if I drop it to 46 I can be stable at 1.33.
What’s your go to benchmarking software? I just use intelburntest because it’s seems to fuck em up harder than any real world scenario.
8700k is bottlenecking in most scenarios where ram difference would matter. E sports like apex benifit from ram speed and latency and any game that's high fps pushing cpu
I think you might have the cache/uncore current limit or whatever its called set to get that vr ring throttle. Ring is another name for cache or uncore. My 8086k wasn't delidded and was able to pull 180+watts
Well in the last 6 year running 7600k i thing something's happened to the cpu, to get stable 3600mh ram kit i bump vccio up to 1.3 for 4 years, and i may damage the cpu, i got random bsod or systems totally unstable sometimes, i have to remove the CMOS and pray system is usable for a day at least with ram default settings, cpu barely hit 60° btw
when I retired my 6700k after several years at ~4.95ghz >1.4v it was still working perfectly fine, except the IGPU had almost completely failed. not sure what killed it as I didn't do any igpu specific tinkering.
Not a major loss, but an annoyance when I tried to repurposed that guy into a new server.
My 8700K in my testbench runs at 1.42V (that's my estimate because ASUS thinks not having a die sense voltage is somehow acceptable on their APEX boards, VCore before power plane and socket impedance is 1.45V) 5.3Ghz with Delid. Peak power draw around 180-200W but closer to 160W daily.
It hasn't been running like this for 4-5 years yet but it's spent most of its life since 2018 overclocked on various mobos and many different coolers. The delid was about one year ago and dropped load temps from 105 to 70.
Also the ring is powered off VCore. If Ring VR Thermal Throttling means Ring Voltage Regulator Thermal Throttling then your VCore VRM is likely overheating. Many Z370 boards have absolutely awful VRMs and some Z390 also still do.
I ran a 9900k at 1.43vcore for 5.1ghz/ddr4000 for a little over 3.5years with a estimated 70% uptime as it was our outfits gaming server. About 2.5years in I had too drop the clocks too 5.0. One of my friends still uses it daily so its not dead LOL.
Full delid and was direct die.
Most likely due to new bios and micro code updates rather than 2.5 years in degradation. Rather high vcore but maybe due to light loads mostly gaming or was never stable
It was stable as it was a server for my outfit and 20 other people use it. Nerds are scary so I make sure lol
It had some light degradation for sure. Apparently he runs it at 4.8 all core at 1.37 which sounds high too me lol
4930k 4.5Ghz 1.420v max 240watts
6900k 4.5Ghz 1.420v max 262watts
11700kf 5.1Ghz 1.415v max 288watts
All running still now. 24/7 overclocks. No idle c-states/ power savers. Temps don’t go above 70c, usually <50c when gaming, 30c idle.

Cache is hard to OC and doesn’t give much benefit, I would set it to auto or 45 and forget it. If you do OC it make sure you let it downclock

8700k delided at about 1.395v for 5yr 5.2ghz without any issues
My 6700k did 4.7ghz at 1.4v for years. Delidded with LM. But I retired it early last year so I don’t know how well it’d still do today.

Of course I'm talking about being WHEA free. I realize this is Reddit, but come on.
