Just in case 
8000 is actually not guaranteed on a 2-dimm motherboard with a 13900k/ks. 7800 is more doable on more 13900k/ks CPUs. The IMC is very important to determine how high you can go with stability. You may get 8000 to work on one 13900k and get into windows, but whether you can pass a ramtest program like Karhu or y-cruncher or whatever is another story..also if you can't run certain games you arent fully stable either. I've noticed the most sensitive games as of late are Unreal Engine 5 games..They are very picky to overclocked CPUs and RAM. On Star Citizen, it is very sensitive to CPU overclocks, because of how poorly optimized it is, it often utilizes 70 and up to 90% CPU utilization at times, which puts way more strain on the CPU overclock for sure. I had to add a positive VRM CPU core voltage of 0.01v to get this game stable along with an LLC of 6. Also using "Extreme" setting on CPU Power Phase and Duty in DIGI+. I've noticed that setting the Power Phase to Extreme instead of Auto or Standard, boosts the Benchmark scores a decent amount as long as you remain in ok temps. Back to the IMC and DDR5 OCs, a top tier binned IMC 13900ks or 14900k can do 8400-8600 MT/s, but thats far from average. A "good" IMC on a 13900ks and 14900k will usually do 8000-8200 MT/s with tight primary timings. For 4 DIMM z790 motherboards typically 7200 is the max they will do, even with a good IMC 13900ks/14900k. Some Asus Z790 Hero motherboards can get up to 7600. It all depends on how well the motherboards DIMM slot connections are too.Define weak. Most i7/i9 can hit 8000 easily without much work with 2 dimm boards. I've even seen a 13600k get 8000+ easily. Bottom line is if you don't even try, you wouldn't even know. Sure IMC plays a part but that's mostly much higher frequencies. Really don't understand what you're saying. People who have a golden IMC are basically pushing much higher than 8400.
I totally agree, I dropped the 6Ghz on 2 active P cores in leu of running all 8 pcores synced to 5.9Ghz, but with TVB enabled to reduce the frequency at 70c to 5.8Ghz and 5.7Ghz at 85c. In gaming I rarely see it drop below 5.9Ghz unless its compiling shaders on a game. BF2042 will utilize all 8 P cores and some E cores as well. Another game to look out for that utlizes all of your P cores and some E cores is the soon to be released Avatar PC game(it's supposed to be multi-threaded well). It's running on a newer version of the Graphics Engine that ran The Division 2. The graphics look amazing so far. They look to rival that of Unreal Engine 5 games.It's just that high singel core boost doesn't benefit modern games that use many cores, like BF2042 does.
Hyperthreading off or on?Well my 102p sp 14900KF maxes out at 5.9GHZ p / 5.2 GHz r / 4.7GHz with reasonable load voltage under ambient direct die with a MO-RA. Hottest cores get to 72C with 22C ambient. 1.25V Vmin. Using 1.390V fixed voltage with LLC 6. 340W during y-cruncher 2.5b
There is quite a bit of thermal headroom at 5.9GHZ p cores, so I think its safe to say any i9 will do 5.9GHz on p cores with a similar cooling setup.
6GHz would need > 1.440 set in BIOS at LLC 6 which I’m not interested in dailying.
I understood from listening to some Asus youtube videos, that using the "Threshold" temp throttles the CPU with an inefficient process that can negatively reduce performance and is governed by the Motherboard and that it over does the frequency reductions to try and bring the temps down. Someone else who knows this better should help me out please? Whereas the Max CPU temp, which I set to the safe intel spec of 100c is governed by the CPU itself I believe. You are much better off to set your Performance Cores to what you want them to be, but use Thermal Velocity Boost to reduce frequency and temperature instead. I currently have my P cores "synced" at 5.9Ghz and have TVB set to reduce my frequency to 5.8Ghz at 70c and 5.7Ghz at 85c. If it hits 100c, Intel's internal mechanisms will reduce your frequencies further to reduce temps to prevent damaging the CPU micro-architecture.Great idea!
how does this look btw, how does package temperature threshold work vs max cpu core temp? View attachment 2634052
On.Hyperthreading off or on?
See this is where it gets fuzzy. Some modern games benefit from HT on whereas a lot of older games benefit from HT off. I leave mine on. From what I understand its kind of a wash and more likely that newer upcoming games will utilize HT.Hyperthreading off or on?
My chip can't do that at x59.
Are you direct die?My chip can't do that at x59.
Instacrash.

I stick to simple old CPU-Z stress test function and running games that are known to be CPU demanding. I simply wont run these heavy stress tests for minutes and then have my CPU degraded because of all these multiple multi-minute runs. I have all power limits removed to increase my performance in light to medium load scenarios like PC Games, which is 99% of what I use my custom PC for. If I were having to run heavy loads often, I would set power limits on my CPU.I will give it a try. But I’m not interested in running something really really heavy for 10 min straight.
You do you. I like 2.5b because it appears to be the best test for the RAM OC and the CPU OC at the same time.I stick to simple old CPU-Z stress test function and running games that are known to be CPU demanding.

What games benefit from HT on?
Games that are well multi-threaded, Like Civilization 5 or even Battlefield 2042 will benefit from HT. Supposedly the upcoming Call of Duty Modern Warfare 3 will be well multi-threaded and benefit from HT on.What games benefit from HT on?
I didn't mean any offense kind user. It's just what I do. What kind of load does "2.5b" put on the CPU?You do you. I like 2.5b because it appears to be the best test for the RAM OC and the CPU OC at the same time.
EDIT: 2.5b only takes 45-50 seconds.
Useful. Thank you.At last, I found: Power Consumption, Peaks and technical Details: Intel’s upcoming Alder Lake S and Raptor Lake S CPUs in an exclusive comparison
From published part of (obviously confidential) document "Processor VR Design Values": IPL2 (A) and IccMax depends by ratio of ~0.66 --> so if you want to get sustained/averaged vrm current then just multiply IccMax by ~0.66
If you have ASUS EC with "VRM Vcore Current" sensor you will see that reported current always respects that ratio (rounding down a bit because IccMax is proactive and CPU frequency step-down is discrete).
Returning to original points:
- using IccMax as sustained current in any formulas is not correct and misleading
- by using official 307A IccMax from 13900K/14900K specs estimated IPL2 is ~203A (but in provided table it is even lower - 194A for RPL)
- if you consider PL2=253W for long-term operation then estimated max.allowed voltage is 253W/203A = ~1.25V (or ~1.30V for 194A)
- to reach "Extreme" config with 400A IccMax (-> 266A IPL2) you must raize/remove PL2 limit - which is out of spec because there is no way to draw 266A within "stock" 253W budget
Huge load. 30-40W more than cinebench. I like that it is a larger CPU load than any game will put on the CPU and that it has such a short duration.I didn't mean any offense kind user. It's just what I do. What kind of load does "2.5b" put on the CPU?
You've tested them or seen legit tests run? Just because a game runs several threads doesn't mean HT will be beneficial.Games that are well multi-threaded, Like Civilization 5 or even Battlefield 2042 will benefit from HT. Supposedly the upcoming Call of Duty Modern Warfare 3 will be well multi-threaded and benefit from HT on.
Yeah definitely like to see the gains at 4k.You've tested them or seen legit tests run? Just because a game runs several threads doesn't mean HT will be beneficial.
