However, I have the P14s all attached to the case's built-in fan controller and normally run them at 7v, which is about ~1000rpm; I only crank them up to 12v if I expect to be running heavy combined CPU and GPU loads for protracted periods of time (or the most demanding of stress tests). The TY-143s are both PWM controlled and sit around 900-1200 rpm through most loads, only reaching 100% past 80C on the CPU.

I like having that extra RPM range to handle outlier loads and ambient conditions, but for most uses the system is more than quiet enough to sleep next to or listen to music with, without headphones.

Only 1.2v cache/ring, or a 150mV offset. I'm using fixed voltages though. Nothing undervolts or downclocks, ever, as the system is normally loaded, or off entirely.

This board has Gigabyte's version of the OC socket, which helps uncore clocking considerably, as well as memory clocking to a lesser extent.

The six reserve VLs revealed are set as follows:

VL1 - 1.39v
VL2 - 1.2v
VL3 - 1.37v
VL4 - 1.44v
VL5 - 1.43v
VL6 - 1.44v

Most people only set VL6, but I found the auto voltages on the rest to be excessive and, after much trial and error, settled on these.

With the OC socket disabled via the switch on the motherboard, or the VLs all manually set to minimum (0.01v for the first three, and 0.9v for the rest) max stable uncore clock is closer to 3.6GHz at 1.2v ring, or 3.8GHz with 1.25v.

Sounds like my systems except I use temp sensors to monitor temp for automatic control of fan curves reaching 1000-1100rpm @ 65-70c then ramping rapidly to full speed at about 80c on rare occasions.

Different tests can isolate specific areas of weakness, so that rather than relying on broad reductions, one can increase margin where it's most likely to be needed. No matter what sort of loads one expects to run, or what sort of margin one is comfortable with, knowing more is only going to help.



How do you know? The idea that instability is always obvious is a fallacy.

More importantly, how do you know your use case is analogous to anyone else's?

You can't have too much stability, but you can have too little.



Pushing a combination of too much current and/or current through a chip at too high a temperature; too much thermal cycling; or dirty power can all degrade parts. However, if these factors are kept constrained, you can run any arbitrary piece of software for any arbitrary length of time and expect a long service life without issue.

Anyway, I have a five year old 5820K and a similarly aged E5-1660v3 here that has seen quite a bit of very demanding stress testing and are still in service with little to no degradation, because I set limits, and in normal use they were way below them. I have certainly killed chips as well, but I consider it better to weed out weak samples early on than baby them to be disappointed later.
The problem here is this.
BOTH of you are correct.

The root cause of the problem is that NO ONE ever discusses what the safe volts/amps points are. I'm probably one of the first people on this forum (or any forum) to raise a huge stink about it. Back during Core 2/Yorkfield/Nehalem/Sandy Bridge, even Haswell, not a single post actually discussed this. All there were were voltage "estimates" with absolutely NO mention of current load. Anywhere. And absolutely zero people knew how Loadline Calibration affected safe current (Amps) load V points with respect to vdroop. The infamous chart on Anandtech years ago was 100% completely wrong--oh, the graph was right (you can't mess up an oscillioscope graprh), but everything they said about it was for the wrong reasons. Why? Because NO ONE mentioned AMPS limits anywhere.
I challenge any of you. Go back five years on this forum, anand, toms, reddit, anywhere and search for anything regarding amps limits in CPU's with respect to voltage. I guarantee you will find absolutely nothing, besides a few random "ICCMAX" posts, with NO explanations from what they mean (unless they come from an Intel poster).

Yet Intel publishes these specs in their data specification sheets. Too bad it takes someone used to reading engineering sheets to understand half the stuff written.

I can't even explain simple stuff like "loadline" and "Amps" and even give a simple *Pre-algebra* math formula to people without them getting all pear-brained. And I'm talking about grown adults here. Even if you type a math formula it's like their brain dropped out of their head into their rectum...

Haha. This is true actually.
If you can get all fully matching residuals with 35000 sample size in Linpack Extreme 1.1.2 or LinX 0.9.6, nothing CPU related will crash your CPU. But good luck cooling your CPU with it Now I do not know how relevant LinX testing is for memory overclocking...Not touching that, period.

I've never disputed that running more demanding loads will degrade a chip faster, but if one has rational limits, a short period of extreme load (and correspondingly higher rate of degradation) will be well worth the extra piece of mind when it comes to stability...at least if one values stability. The lower clocks, voltages, and temperatures that I settle on will also likely result in greater long-term longevity as well, despite short periods of extreme load.

Take this 5820K for example. I reevaluate the OC I settled on the first year I had it about once a year, usually after changing some other element of the system. After it's initial break in period, I haven't noticed any measurable degradation and the part is five years old, with tens of thousands of hours of load on it. A few hundred of those hours being stress tests isn't going be any great hardship for the limits I've set, and most other OCers would be using a solid 200-300MHz higher OC with 100-150mv more core voltage, all other things being equal.

It's difficult to talk about what current, voltage, and temperatures are safe in isolation because if you reduce one, you get more headroom for the others, within reason.

I've mentioned current limits in these arguments since I joined this forum, back when I was running S939 Opterons and Core 2s.

OCN's search function is garbage, but I was able to quickly find a few posts where I mention current draw:

https://www.overclock.net/forum/5-in...l#post25173829

We're certainly not the only one who has mentioned current and it's relationships/limits.

There is a reason I'm not referencing IccMax...I can dramatically exceed spec IccMax on almost any part, and have parts that have been run nearly 24/7 for a decade-plus that have been past IccMax the whole time. However, I rarely get anywhere near anything like absolute max voltage ratings, or even the VID range limits on parts. Both the voltage ranges and current limits in the whitepapers are only useful as very rough guidelines. IccMax in particular is extremely arbitrary; it varies with TDP, which in turn can be wildly different between parts of the same architecture and die flavor...even parts that could well have been cut from the same wafer and assigned to an SKU randomly. Collected anecdotes about what's killed or degraded what are more relevant figures.

Anyway, I've been reading the datasheets on my parts and have been aware of loadlines and stated current maximums since before I was a member of this forum.

Ultimately, cooling limits dictate voltage and current limits for me.

I can demonstrate otherwise fairly easily, on some platforms, including Haswell-E.

OCCT, for example, will almost always crash very quickly at the minimum core voltage it takes to be stable in LINPACK, or even a few notches higher. Sometimes even certain Prime95 FFTs will. Even enormous runs of it aren't a great indicator of CPU stability. I can do 500 loops of 35000 problem size in Linpack Xtreme 1.1.2 with all matching residuals, and then fail in a few minutes of OCCT large data set, and this is readily repeatable.

I mostly save LINPACK for testing thermals and power delivery because of this.

Yup forgot about this thread alright
Just got my D15 chromax today and installed it, bumped the 5820k to 4.5ghz and now idles around 29-30c with 18c ambient and somewhere at 55-60c full load.
This cooler is amazing, now my laptop is louder than my desktop.
To be fair the paste under the H90 was all but dried up so I could have definitely gotten the temps down but I did notice some corrosion on the fins of the rad (almost like something seeped out) so it went straight into the bin.
Will wait for intel's next chip but might also try AMD since apparently they are not as bad as 5 years ago - let the flamming begin hahaha
