is my 9900k overclock safe?

[pumbafriis]

I have overclocked my 9900k to 5ghz on all cores with 1.332 V and LLC on 7 hitting max 77 under full load. is this safe and will this OC affect the lifetime of my CPU much?

Looks pretty good...high voltage is what will reduce the life. 1.33 is a BIT high (i've seen 1.3 is pretty standard), but nothing crazy. Voltage OK, temps good (depending on what you mean by "full load"...like full prime95 load?). Should be ok, but make sure to stress with something like p95 or RealBench.

That is a reasonable temp but the voltage is literally right on/over (1.3V or less for me) the line of as high as I like to go for a 24/7 OC. But I know there are those who say up to 1.34 or so is OK too so some of this is on your comfort level.

LOL I saw your voltage...right in line with my thoughts.

Is there any settings that can help with getting the voltage down a bit?

 

[atomicWAR]

Voltage droop might help...but it might kick your temps up a hair, might not. Assuming you don't have it on already.

Actually to answer better post your full bios OC settings (screen shot or text is fine)

To be clear your voltage is not bad it is just a hair high...acceptable just not ideal.

LLC on 6 not 7

Ok but what are your bios settings?

Yep and going over them now give me a few to analyze them.

So yeah you are already minimizing Vdroop with load line calibration. You could try going to 7 but lowering your CPU voltage to 1.3 even or lower if you can stably.

I'm now trying out 1.310 V with LLC 7 but acording to CPUZ the voltage sometimes spikes to 1.350 is this normal?

 

[atomicWAR]

Yeah it is...you may be able to lower cpu Vcore even further because of this. We were hoping for this to happen...So under load Voltage gets a kick up higher and doesn't drop as low idling to increase stablity. In theory you can use lower Vcores for the same OC because of this. But your on your last level of load line calibration so you won't get much further on lowering the voltage. Question does going to 7 allow you to lower the Vcore low enough to make a difference in heat and overall CPU voltage.

I'm sitting at 66-77 degrees under load, not sure what you mean with overall cpu voltage

So when your under load your CPU voltage will peak at it's highest and dip when idle. With or without load line calibration. LLC just allows the voltage to not dip or spike as much. Giving you a higher steadier voltage overall during operation but bringing down the Vcore being used so you CPU isn't hit with those extreme dips and spikes as much. Making it stabler at lower Vcores. It's always sounds backwards to me but it works. It will work your motherboard and PSU harder but this is true of any OC.

I got the voltage down to 1.275 with the highest spike being 1.314 running intel extreme utility stress test

Now that's what i was talking about right there!!!!
