Yeah that was what I was thinking, for more vdroop ( less voltage during load) one needs to progressively add higher positive values. The higher the positive value the more it is going to "vdroop".
Negative numbers would increase voltage under load.
 

Those were my observations as well, with the slight caveat that you could still receive a droop (less voltage under load) with a negative number setting as the voltage change (vdroop or bride lol) is based on what your voltage would be from Intel's standard droop.

For me, my vcore is set at 1.340v and vdroop set to -25, vcore fluctuates between 1.337 and 1.340. Pretty darn close to rock steady at 1.340.

Nice!

Thanks, much appreciated. Trying to see what I can take the 6cores 12 threads to, and pump out some cinabench scores.

1708 @ 5.4ghz 6 cores 12 threads. Didn't run one at 5.56ghz yet because it was an afterthought to climbing the cpu frequency leader boards with the 5.858 1 core

Just ran and passed a 20 minute stress test with Intel Extreme Tuning Utility on my Z390 Dark and 9900k. All still at default settings.
CPU core temps typically ran in the 50's and 60's with an occasional spike up to around 70. Highest a single core got was 72c.
 
Hopefully I have some room for overclocking my system. Doing some reading up on this and hope to begin the process here in the next day or so. Very pleased so far with the performance I am already seeing out of this new rig. 

what cpu frequency?  and go at least 30 minutes to an hour.

Just the default right now till I figure out the overclocking.

onMute
Custom loop with 2 360mm radiators
9900k @ 5.2GHz (x52)
VCore: Override set to 1.340v w/ -75% VDroop
AVX Offset: 0
DIMM: 4133MHz 17-17-17-38 @ 1.45v
 
Cinebench: Passed w/ 2280 - vcore spiked to 1.4v w/ CPU temp ~80c
Prime95: All thread workers passed for over an hour (min/max FFT size set to 1344, run FFTs in place enabled) - vcore maxed at 1.391v w/ CPU temp 60-65c
 
When I tried to tighten up my DIMM timings to 16-16-16-36, Prime95 failed about 20min in. I'm going to try 1.5v on the DIMM to see if it will pass over an hour.
 
Do you think my voltage settings are too high? Overall, very pleased with this board.
 
voltages are fine, however fixed 1344k prime95 is no stability test, the load on the cpu is rather low compared ot a full custom run.

what kind of LLC are you guys using?
 
I'm using -25% which is almost no vdrop.

That's what I'm using and same observation. My vcore is set to 1.340, drops to 1.337

If you are talking vdroop, I am running -50%.

Excuse me I double checked, I am running +50% on Vdroop, not -50%.

what's your SA/IO at?
 
your cpu is idle at 60c right? no way in heaven its 60c on load.

whats' the ramkit you having?
 
I'm at 1.42 for 5.3Ghz. getting about 80-85c with prime95 benching. Heatkiller IV (no direct DIE) and 25c water temp

check my pictures on the previous page maybe you can copy the timings? 4600 you have to have really good IMC. you should be able to do at least 4133 though.

I can't get them even to work, without that not lapping :)
 
I can boot stock settings with OC frame, but any OC will result in bootloop, while it works with stock frame.
 
too much sa/io can fail too.
 
try 1.28-1.3 SA/IO with those settings here:

or try these: 4000 https://abload.de/image.php?img=4000qjecr.png

So after testing for 2 days, my stable results; 5.3 ghz, 2 avx, 1.45 vcore, - 25% droop, my ram problem continues in a different situation. I am not expert in overclocking. But read a lot, try a lot. Learn from you guys how to push limits. So my situation evolved like this. At 5.0 ghz, 1.35 vcore, 1.4/1.4 sa/io, 1.6 dram voltage
 
I can work my rams stable at 3900, 15, 15, 15, 2T
 
Post but bsod on benching at 3900, 14, 14, 14, 1T
 
What ever I do system not posting at or above 4000 mhz. It is like there is a wall at 4000 mhz. 4000 mhz with 20 timings even not posting.
 
Could it be a bios issue or just my 9900k imc is weak? I pushed dram voltage to 2.0, sa/io 1.5/1.5, nothing changes. Same bootloop. System not even trying to boot :)

Read over kingpins article in the OC Lab area if you have not already.  What temps are you seeing at 5.3 on the CPU?

62-68c on load, I have direct die cooling. I' ve already read that article. My problem is that something looks blocking the imc from training. But I have very little experience on memory oc. So probably I' m wrong. 3800-3900 mhz, when I tighten timings, I can see the training on the display, sometimes takes longer. But after 4000, directly bootloop comes like Kingpin mentioned. I try everything but bootloop sequince not changing. Not getting longer, or shorter.
