APEX ENCORE +14900KS +Dominator Titanium 7200 stability help.

[SinisterDev85]

Long time no see folks! 

Got this new build together and I've been riding the struggle bus trying to get a modest overclock stable.

Im honestly a bit overwhelmed with all the new settings this board has vs my previous Z590 Apex. Unfortunately it doesn't seem i hit the silicon lottery this time. My cpu scores a mediocre SP93/MC 75.

After some recommended voltage tweaks I've successfully been able to get the memory running stable in XMP Tweaked profile. Ran memtest in the bios and it did 7 passes with 0 errors.

I decided to tweak just a few familiar settings and see how good a job the AI overclock does. Made it into windows and ran Cinebench 24 and followed the usual routine for the AI to set a decent OC.  However, trying ro get that OC to run while on an XMP profile is where I've hit a roadblock. After about 5-10 seconds of running Cinebench, the program freezes and I need to force close it.

So here's so more details. I feel like im close to discovering stability. Im using the new TG Contact Plate and TG Kryosheet. This is my first time using a contact plate. At first I tightened down the thumb screws too much and that was causing instability issues. Cpu would thermally throttle instantly upon starting Cinebench, however my H170i would bring the temps down quick, but temps did spike high throughout the test. After redoing the thumb screws by hand only, not using a screwdriver, the difference was night and day!! Cpu never thermally throttled during the benchmark and temps overall were much lower. Lesson learned!

So now im trying to get a decent cpu overclock with the ram running in one of the 3 xmp profiles, and that's where I hit a wall. I think im going to have to abandon the AI OC and start manually tweaking the cpu. Which has been a little intimidating cuz i havent done this since the 11900k lol. Sooo many more options now.

Anyone have any advice, or could point me in the direction of a good video guide to watch? Im not seeking the highest OC available. I just wanna get a nice moderate cpu oc, hopefully with ram running one of the XMP's, and perform an undervolt (which i also need some direction on how to do properly.)

Im having trouble finding a helpful guide for my specific configuration. If anyone has any advice or can point me in the right direction, I'd appreciate it! 

Btw, it's good to be back, fam!

I'm having trouble getting it stable at 5.9 all core. It keeps downclocking to 5.6.

• Intel Adaptive Boost Technology - Disabled
• Asus Multcore Enhancement - Disabled Enforce All Limits
• SVID Behavior - Trained
• Performance Core Ratio - Sync all cores at 59
• Specific Performance Core Ratio Limit of 59 on all cores, with specific voltage to auto
• LLC set to 2
• Actual VRM Core Voltage set to 1.55, which is a little high yes
• Regulat Frequency by above Threshold - Disabled
• TVB Voltage Optimizations - Disabled
• Enhanced TVB Disabled
• Overclocking TVB - Boost Until Target with Max Boost Target at 5900
• V/F Point 8-11 Offset - Negative 0.001
• Windows Power Profile is set to High performance with both Min and Max CPU state at 100%

Note, under AI Optimized Settings it's giving a P-Core SP of 119 and an E-Core SP of 82. Under Prediction it's 106.

I'm still trying to wrap my head around the interplay between all these new settings in the bios, but ive been following this helpful guide https://www.overclock.net/threads/asus-maximus-z790-and-intel-i9-13900k-14900k-an-overclocking-and-t...

Based on what I've been reading, you may have better luck trying a per core tuning, vs sync core. Seems like you can get more performance out of your system that way. The author makes it sound like core syncing is nice for trying to get higher scores in benchmarking software, but that doesn't necessarily reflect the performance and temps you'll be getting during typical real world tasks. 

Ive been following the per core recommendations and learning how to fine tune things better, and I am seeing more stability in my system. Way less bsods and crashes. Granted im still trying to get everything dialed in with the cpu so I can finally move on to getting xmp stable as well. 

[SinisterDev85]

Your cpu is binned better than mine, for sure. I've really needed a refresher course, and to get familiarized with all these new settings and how they interact with one another.

I FINALLY managed to get the system stable enough where I'm running the Dominators in XMP 2 and can make it through some stress tests without bsods or crashes. So Ive made progress! 

Im trying to work out a similar issue that you're having. Something is causing the cpu to ignore the per core clock settings I've dialed in, and my E cores drop to 43 and p cores drop to 55 during Cinebench runs.

I think the answers lie somewhere in the TVB and Asus OCTVB. I just FINALLY got Asus OCTOOL working, which should help me figure out a number of issues, and cut down on the time it's taking me to tune the system.

I started at LLC 4, leaving DC_LL on auto for now and started with AC_LL at 0.20.  Worked my way down to LLC 3. AC at 0.40, and i think i can definitely keep dropping AC. 

If you're LLC is at 2 right now, you may need ro manually adjust your AC_LL manually to a higher number. Starting around 0.60. I think that may be at least one area that needs tuning for you to find stability. 

From what I understand in the guide I linked in here, as you try to step down to lower LLC levels, you need to adjust the AC LL, starting at a higher value and gradual reduce it until the system becomes unstable. If you successfully reach AC LL 0.01 and the system is stable, you then can reduce your LLC one level and start the process over. Some people do this, tuning all the way down to LLC 1, but its quite tedious. 

The guide recommends starting at LLC 4 with AC_LL 0.20 and DC_LL 1.02.  And working your way down from there. 

Supposedly on the z790 boards DC_LL will actually sync DC_LL with whatever LLC you choose, if you leave it on auto.  Therefore you can spend more time focusing on tweaking AC_LL. However, in order to tell how well the Auto DC_LL is working, you have to monitor your VID and VCORE when the system is under load. They should be around the same voltage give or take 5%. If they're further apart than that, you may have to make small tweaks to DC_LL and AC_LL until you narrow the gap. That's the point im at currently. My VID and VCORE are a bit too far apart, but im getting them closer. 

You're going about things different than I am, but I think playing around with the above tweaks might help you get things stable. Or get step closer, at least. Its definitely helped me make leaps in progress today.

So I've updated my title because I ended up swapping the K for the KS. My return window would have ended the day after the KS release. Micro Center was charging a fair price for it, and with the discount for using my Insider card, I didn't have to spend a ton more for the KS. I was disappointed with the abysmally low binning of the K I purchased and hoped that I'd have better luck with a KS.

I didn't win the silicon lottery. Only a SP99. 112 P core, 73 E core and 82 MC. Disappointing Ecore score, but the MC is 12pts higher than my K. So I expected significantly better results with the memory.

Unfortunately im still having a much easier time with the 7200 Dominator kit. The 8000 GSkill kit is still being very problematic.

I decided to focus on tuning the cpu first. Getting that all dialed in and stable, and then finally seeing which kit I have the best luck with running in XMP.

I've been following this guide, which has been helpful, albeit a little brain frying lol https://www.overclock.net/threads/asus-maximus-z790-and-intel-i9-13900k-14900k-an-overclocking-and-t...

Still having a hard time wrapping my head around some of it, but I am slowly absorbing the information. Things have definitely become a bit more tricky since my last build. And this current gen of cpu/mobo seem to be more finicky than their predecessors. I really wanna get everything stable and get back to gaming/streaming. It's been too long. 

What luck have y'all had with tuning on the Apex Encore? Any recommendations for bios settings? Have you updated to the new v1101 bios? I seem to be having more luck with stability since the update. Been able to successfully run benchmarks and stress tests with way less crashes or bsod.

I'm currently rocking the 13900KS + Apex Encore + Corsair Titanium 48GB 7200mhz using this memory settings 38-48-48-52 and was able to overclock it to 8000mhz, tested it with Testmem5 using Anta's absolute configuration for 4 hours without any errors.

[SinisterDev85]

Dayum, congrats! Im hoping that once I get the cpu tuned better, that I will find similar success with either of the two kits i have sitting here. I couldn't even log into windows without a bsod on the 14900k that I returned. The IMC was really weak. The one on my new KS seems to be better, but I won't know how much better until i get the rest of the dang system tuned and stable first! It's been quite a challenge. 

[Kimbaduds]

I was planning to get the 8000mhz of corsair but decided to test my current ram out first, I was surprised that it worked flawlessly. I started tweaking the timings until I boot to windows without getting error. maybe I got lucky with the ram. 

Currently using XMP 2.

Hey, I've been following this thread for a little as I was having problems overclocking the same ram ( G.skill z5 8000 mhz out of box) on the apex encore at 8000 and 14900k non ks. Not sure if the z5 comes in any other speed and or if you had the 6 or 7000 version but I wanted to share that I got it working with a few small changes mostly mentioned here. 

I also wanted to suggest that you consider one of your other parts if faulty because my non KS 14900k has a lower score than yours and I don't think it's your issue. 

Someone on the first page of replies gave very specific voltage ranges to try out on a few settings and those changes gave my ram the boost it needed to be significantly better.  I'm still dialing in on the sweetspot but can play all my games wether it be poe, league, dragons dogma 2 without any crashes or stuttering besides rare occasion. I haven't crashed at all on the most recent voltages I tried and hopefully it stays that way but even if I do I'm confident the stable voltages will be very close to where I'm at. 

If you haven't already found voltages that worked for you let me know and I can leave them in a reply here. I'd leave them right now if I was at my pc. 

I've tried a few other ram kits and on 3 separate apex encores and they have almost all been unstable until I focused on these voltage settings, and I really understand your pain lol because I was on this forum pretty much getting the same help from the same mod with overclocking my ram on the asus board I had before upgrading and they weren't able to solve it for me and it took me probably an extra month possibly more of not being able to enjoy my pc or any games until I finally swapped out some parts and rebuilt the pc from ****** near scratch and it was all going well until I recently noticed my ram was dangerously unstable and the settings i mentioned earlier from page 1 of this posts replies are really sealed the deal on fixing my issue.

If voltages don't help the rams stability you might seriously want to consider needing to replace other parts on your pc if the ram doesn't need to be replaced first. If something else is even slightly broken it would be really hard to tell and no amount of bios changes will get the ram stable in the long run if that's the case.

Just lmk if you need the voltages. Good luck though!

So I've learned much since I first posted this. And  I still feel I have much to learn to get everything running the way I want it to. 

I was looking at intel's specs for the 14900ks and noticed that the extreme phase settings expand the amperage and wattage up to 400 and 320 respectively. So i decided to start with setting them to those levels and see where I can get with it. Honestly I haven't thermally throttled in testing since. Even when it hits that 320watt mark. With my current cooling solution, a TG Contact plate, TG Kryosheet, and a Corsair H170i Link in a push/pull configuration, I seem to be able to keep the system from thermal throttles as long as I set the wattage limit to under 350. Once we hit that area, cores hit 100c. So Ive been sticking with the 400amp 320 watt limit.

I started tuning AC_LL and DC_LL to get VCORE and VID as close as possible as part of the tuning.

There's still some troubles im running into that I can't quite figure out. Like it seems as if no matter what multiplier I set P and E cores to in the bios, ot doesn't wanna run at those speeds under load, even when no thermal throttling occurs. For example, soon and I start Cinebench r23, the cores drop to 5600 and 4400, and that's definitely hurting my score. It's not even pushing the cpu to the 320watt limit I set. Im sitting in front of the pc now and its not going over 275watts. Package temps haven't gone over 85c. No thermal throttling whatsoever, so what's causing the system to downclock the cpu immediately when being stressed. I feel like i should know what's going on, but apparently I'm still too rusty with all of this.

Im wondering if i should just try syncing all the cores to 59x or something like that and attempt to achieving stability that way. Even if its less efficient and "doesn't make sense anymore" according to the Overclock.net guide I've been reading through. It really sounds like per core tuning is better overall, but its being such a pain.

It's taking me way too long to get everything running stable. And I still need to get the RAM running properly after this 😮‍💨

Do you use any contact frame?  if you remove it and use the standard retention system
