Yah that combo of PBO and ECLK is very strong. So you can boot into windows and run dawntrail at +200 offset, 0 CO, 104.2 ECLK. Can you run cb23 there? CPUz bench? 3dmark cpu profile?
I can run whatever. I've been gaming on that setup for a few days now, it's solid. It's hot and power hungry but solid.

CB23 doesn't scale due to PBO limits. It only holds about the same as without eCLK so 5450 ish 24100 points. Games don't hit the limits so it fully boosts. I assume cpu-z and maybe 3dmark will also limit but let me run it anyway.

EDIT:
K so I used my 8000C34 profile as that has very low vSOC/VDDIO/VDDP requirements leaving more thermal and power room for PBO on the chip.
CPU-Z on PBO +200 -30 CO gets 9010 multi and 833 single.
CPU-Z on PBO +200 eCLK 104.15 0 CO gets 9158 multi 870 single. It still limits it somewhat as clocks sat around 5520 all core but 5650 in single.

I don't have steam or 3dmark installed on this OS so not sure if I can be bothered to install it right now.

I'm curious to see if I can get away with something in the middle so like 5500-5550 with some heavy - CO to make it boost higher in Cinebench... Let me try some stuff in OS with SMUDebugTool for some on the fly CO adjustments. It won't be stable as Cinebench can pass with a very unstable CO but still.

EDIT2: won a few points in R23 and got my highest score yet. 102.3 BCLK for 5550 with -20 CO it holds around 5470 now. 5550 hard froze with -30 CO, let's see if I can get 5500 to run with -30 and allow full boost.

EDIT 3: 5500 101.40 eCLK passed with -30 CO but score is the same. It doesn't boost any higher. I wonder if I can use the same trick as 7800X3D and actually use a - fMax boost to trick it into running higher PBO clocks..

The testing continues..ok the amount of eCLK needed for this is getting quite ridiculous but hey it still boots at 107.20. I'm trying 0 fMax now with 107.20 which should be around 5600 all core as well. It's very unstable as it also uses a totally different point on the v/f curve so 0 CO is less voltage than -30 gets on +200 but it ran cpu-z locked at 5600 and 9340 points. It's absolutely ripping but Cinebench insta locks up. But yes, that does work. Less fMax + more eCLK = higher boost ceiling under load.
 
What is the best kit 64GB for Zen5 ?

All super interesting! Thanks for writing this up
 
cpu should be here soon along with the last few parts needed then onto testing, should I be aiming for 16x2 or 24x2 and for speed should I just grab something like 6000 or a 8200 kit? I still have a 8400 24x2 from my intel setup but figured I would atleast grab a 16x2 also - i assume 32x2 and 48x2 isn't worth it? I always ran 8400c36 on intel so ideally going to oc as much as possible
 
Dual rank 64GB memory with a 9800X3D at my everyday settings measly 6000 MT/s

VSOC is at default in the BIOS. I suppose since its dual rank it runs elevated.

lol I have got the same FPS in games at 4K for Years not matter what gear I have.
Actually with games like Cyberpunk it varies over time.

9800x3d is not different with playing games at 4K max settings than an other CPU but I bought 3x98000x3d just for fun.
f the low 1080p settings for normal pc gamers I saY,if You got a RTX 4090 as of this post and need to plaY at 1080p/720p low settings have fun

Hell this 9800x3d run is not the best I ever had but feel free to post our scores at 4K

You are misunderstanding, nobody is playing Cyberpunk in 1080p low. We are only benchmarking that game because it's a good tool to measure CPU performance (as long as you keep the graphics low enough that the GPU doesn't interfere with the result)

Why, you may ask? Because there are tons of games where you are already limited by your CPU even with 4K Ultra, and in a few months the 5090 drops and 4K will pretty much perform like 1440p does now, and guess how many games are CPU bound on 1440p? Almost all of them, some not as bad as others, but I have seen many drops to double digit FPS in various games, and I definitely do not want to see that on my 360Hz monitor.
