hi guys. i have question. i bought new Cooler NH-D15s and wanted to OC my 9900KF. And if i try manual 1.2V i noticed that LLC is completely useless LLC4.5.6 is same 50-60mv Vdroop and LLC7 is 30-40. But on my previus Z270 APEX LLC 5 was Vdroop 30-40mv, LLC 6 10-20mv and LLC7 was overshoot. I didn't try LLC8 on Z390 apex because it will overshoot real hard or it will be the right sweet spot? if so why is said in bios that higher LLC cause overshoot but so far i noticed just Vdroops? So if i recall corectly 1.2V in stress test i get 1.160V and multiplier x49 is kinda ok i just try cinebench,aida64 and games. So of course i want try 50 but no sucsess. I tried adaptiv 1.2V offset + 0.010 = 1.3V no matter what LLC i use. So i tried AC/DC 0.01 nope still 1.3V but if i put offset -0.010 i get 1.295V so maybe i try bigger offset -0.050 and get 1.175V (on my z270 works adaptiv great 1.280V offset +0.01 and i have 1.275-1.285V) Before i upgrade cooler i use negative offset -0.110V LLC4 and have 1.165V. So if i decrese offset to -0.040 i should get around 1.235V? But with this i can't even boot. If i look on review videos it looks like old bios work as intended but new bios look is kinda broken. Iam somewhat disappointed. if i look at my Z270 that work absolutely awesome and now this (maybe i overlooked something in bios does Z270 work that different than Z390?) , or let's hope asus will do new bios that fix my problem because i saw that few people have problems with new 1302 bios.

upd. so Offset is bad for OC so much hassle. I manage LLC6 adaptiv 1.215 offset -0.025. So now have 1.280V max and 1.225V load 5G stable temp 80c. But every time i set diffrent V or LLC i think the PC doing total opposite that i want...

Not to paraphrase Batman Sir,

but what you want is maybe not what you need here.

So the new is not like the old: check.

Kindly use LLC5 and manual vcore and start fresh to find a stable vcore.

To get a good scare you can leave svid on and see in HWinfo64 what vcore values have been backed into your chip for the given CPU multiplier up to x50 i believe.

And search for "Why some Vdroop is good" in the interwebs.

Good Luck !

So finally figure out my problem. Found that if using adaptiv i can't go lower with voltage than my VID is. so that is why i always get weird voltage and second Aida64 now using AVX...
But now after i solve this out. I was Using MCE-auto and didn't notice any power limit so would you recommend turn off and set power limit manually or let it be ? So now Adapt 1.3V offset -0.045. max 1.25V .AVX load 1.17V a non avx-games 1.210-1.225V seems stable.

Our dear Shamino did take his time and has put up a really comprehensible sticky thread about MCE and other very interesting topics.

To quote one of my personal favorites of his:

"Really, just leave MCE at auto if you plan on overclocking, it does you no harm." - Shamino / Super Moderator



As to your voltages: If you can rock them on a day to day basis, good on you !

Enjoy the rig for a while !

And since it is NOT a "mission critical rig" do not concentrate on prime95/avx or OCCT.

If it's destiny 2 stable you are good to go.
Let HWinfo64 run in the background.
Check for: "Windows Hardware Errors (WHEA)"
If you find any after gaming up the voltage.

If you get bored:
test your RAM with AIDAExtreme - "Cache and Memory Test" .

The first row should be around the 50.000+ mark and below 50 ns (40 would be golden).
If you are in the 30.000-40.000 mark it is time to read some guides about simple tweaks to the RAM(s) - tertiary timings.
Nothing fancy - just the basics
Copy importan stuff to your 2Tb drive first. Chances of ruining the OS are a very very small possibility.

ohh. found it. thanks my bad

So my memory latency is 43ns i have this BLS2K8G4D30AESBK 3000Mhz i have enable XMP but manualy set 3200 Mhz

play more with 5Ghz because i ran into problems so now
LLC5 adapt 1.3V offset -0.040 Max 1.26V AVX load 1.170V nonAVX 1.23V 83c

LLC6 1.3V offset -0.080 Max 1.23V AVX load 1.185V NonAVX 1.2V 88c (using this)
