Also @Owterspace how are you keeping your CPU that cool?
Thermalright makes good coolers, Fractal makes good cases, and Canada makes good winters :)

Edit:

With the furnace running to keep us from dieing, the basement is a lot warmer than it is in the summer..for now.. it will get colder soon.
 
Yeah, but my U12A shouldn't be too far off from that cooler either, and my case is well ventilated. Are you running those industrial fans at max speed lol?
I have A14s at the bottom of the case, but they aren't doing much. I have the 3K 120mm in the center position on the cooler, and I let it spool up. I was just trying to keep my ram cool as they are getting 1.6v right now.

Edit:

I have an FC140 and it is a better cooler than PA120, but I damaged the mounting system by overtightening. Oops. To be fair between 4 CPUs and 2 boards and testing different TIMs I had that cooler on and off probably closer to 100 times if not more. I would have ordered a kit for it but I was able to get a white FC140 on sale for 35 so I jumped on it, should be here shortly :)

Mine also seems to only be capable of 4450 at any given time despite it reaching 4.55 on several cores in the Cinebench ST test.

Also @Owterspace how are you keeping your CPU that cool?
You can only reach 4550 on about two cores under heavy ycruncher load, maybe three cores for less load. All core is intentionally limited to 4450, and if you're on Windows 11 you won't see 4550 that often in normal use (not ST benchmarks). Just how it is, the boost algo works differently for 5800X3D than all other Zen 3 CPUs, and unlike the other CPUs the all-core clock limit is strictly enforced
 
All of the cores are capable of hitting 4500, I just don't know why they don't. If I run Aida I could have 4-6 cores/threads hit it without batting an eye. Kinda weird but probably a self-protect feature so it doesn't get hot.

Edit:

Not sure if its just me, or a chipset, or just a built-in thing... but I have never been able to get it to do 100% EDC.
You don't like changing power limits right? Might be hard to max out anything at 142W which is way more than it usually needs. Set something lower and you'll easily max out in BBP test
 
So what benchmarking software are you guys using to show and prove improved performance for gaming over your 5800x/5900x/5950x CPU’s?

video games...all of them

Awesome , but what did you do exactly for achieve this result ?

CPU LLC ?
I just entered -30 in the CO tab, then save and exit 👍🏻

I saw some mentions of PLL in this thread. However I find it hard to find more information on how to find and change it. Anyone could explain a bit more about it please? Thanks.
 
Hello, has anyone tried this CPU on Win7?

I have a CH7 Hero motherboard with a 2700X installed, and i know i can swap the CPUs over, but i was wondering if there are any new lockouts/hurdles in place when adding a new CPU to the board with Win7.

I'm at the stage now that i need to get another SSD to install Win10 to play some other games, so i will do that soon.

I do have a 5950X system with Win10, but only because there was no way for me to install Win7 on the CH8 extreme.

Understood, ty.

Alright, just came back from work and to my surprise, it's stable at my tuned D.O.C.P. timings with a bump to 3733 MT/s & 1867 FCLK. At least this if I can't have 3733 CL14 or 3800 CL16. 16000% coverage should be stable methinks...

Honestly for this CPU it should be about the same between all those memory configs in terms of performance. Memory isn't that huge of a factor due to its very large L3 cache, it is a special chip. Next I'll mess with the L2 prefetcher to see if disabling it brings me any actual benefit other than nice AIDA latency numbers.
 
Now that PBO is on most mobos newest bios update for 5800x3d. What are your guys settings? PPT TDP EDC , -30 curve ofc. scaling auto or x1? It seems auto is x2 but I am not certain.
120 PPT, 85 TDC, 115 EDC, -30 curve on all cores except core 6 and 8 which are -18 and -23 respectively. Scalar is useless, so is increasing limits on this frequency-locked CPU (from my attempts, it isn't even possible to increase these limits - not that this CPU would ever even approach the stock limits, because again, frequency & voltage locked).

Best thing you can do is lower the limits as much as possible with a CO curve applied for maximum performance & efficiency. Lowering limits increased my Cinebench scores by 200. And I simply cannot believe that I am playing games at 50-70W on the CPU while beating a 300W+ 12900KS, even 7950X in some cases and coming close to 13900K. I love this CPU despite the memory troubles, which are now in the past.

3733 is a good place to be, I can't go any higher due to throwing automatic 07 code at 1900FCLK (MCLK works fine) so I'm at 3733CL14 too.

If you ever want to verify that cores can hit 4550 just fire up some corecycler or set only 1 core to run in ycruncher.

Just takes a bit of getting used to, since on other Zen 3 it's a very simple relationship of less load = more clock, while Fmax on 5800X3D doesn't always go to 4550 at idle
