So what did you do? Removed PBO?

no i kept pbo as negative 20 its fine. my initial was 30 which didn't work cause i had 1 crash. i donno if it was because of this or something else, but i changed it to 20 anyway just in case.

so far no crashes, so it's likely because of 30 setting.


i used a combination of a few sources to figure out how to set the pbo tunning



this one skip to the bios section, he covers pbo there



the 2nd video is useful since it uses the new msi bios UI, so i used that to find the settings i needed to change.

While i was at it, i also added a thermal limit of 85C. So no matter how crazy it wants to get, its capped at 85C max, after that it should behave itself. That said these are my hwinfo stats for cpu temps

min 51.5c
max 76.9c
avg 57.4c


This is considering i did the gaming + streaming + browser with dozens of windows open (tabs asleep), with cpu and graphics card utilization close to 100% So quite good since it didn't even breach 80c yet.


Will do the benchmarking u suggested soon.

done. no crash. cpu maxed 75.5c

ran occt for 4-5 hours back to back

i was wondering why my cinebench score was lower than a 5800x. seems this might be why, though not sure.

I did enable this feature in bios, but google say its not worth enabling at least for the 7800x3d

https://www.reddit.com/r/AMDHelp/comments/1...de_in_the_bios/

https://www.reddit.com/r/MSI_Gaming/comment...yzen_3d_vcache/


this X3D gaming setting in msi bios was only meant for the 9k series X3d cpus, not for the 7800x3d with a single ccd.

I didn't know. i simply saw it say X3d so i thought that should be enabled


for something like this in bios, MSI REALLY should give a note to warn users, ONLY for the 9000 series X3D cpu, not for the 5000 and 7000 series because that enable setting for X3D gaming worsens performance only for those other cpus.


*update

wow big difference



see the cpu utilization especially well i didnt have my tvuber app running but still. also we won the game after making that change haha


if colors r off its cause im playing in hdr so apex hdr is enabled. but in obs i have sdr encoding enabled since hdr encoding doesnt work since rx7800xt lacks the encoder for hdr apparently

For X3D CPUS with multi CCD cores, regardless of generation. King CPU 9800x3d oso single CCD so same same it wont benefit from Game Mode but it will for 9950X3d & 9900x3d & 7900x3d & 7950x3d

You should try understand how Gaming Mode works before generalising its function based on CPU gens.

well thats what reddit said, not my quote

i thought the 9800x3d was a 2ccd though? was i mistaken?







They also changed the placement for the X3d cache thus improving the cooling for the chip because cpu cooler has better direct contact compared to before. Lessons learned from 7800X3D implementation then they changed things up for 9800X3 or so i read

Dont just trust reddit esp when real facts can be had from more legit sources such as Techpowerup, Techspot/HUB, Guru3D, etc. Reddit just bunch of peeps spewing whats in their head whether its true or not.

of course. when did i ever claim to blindly trust reddit? thats y i link source and let u judge for urself haha cauz even im not sure either hence i am also hinting at asking if this is true or not, maybe u didn't catch on to the implied question . im self taught. So i mostly learn by trying. Not simply do nothing then walk away.... thats not how u learn new things..... haha.. also pretty sure i'm not the only one who made the mistake seeing x3d gaming and enabling it cause they had a x3d cpu, it's an honest mistake

anyway just to recap, found the fix. disable that x3d gaming mode in msi bios. Not recommended for 7800x3d.



Anyway the point i was trying to make is, anyone curious about a am5 build like mine, especially when paired with an older part like a rx7800xt graphic card, can it do gaming+ streaming on obs ALSO with music and vtuber software? Yes. I got averages of more than 200 fps. And i saw the utilization was even under 70% for the cpu. the graphic card though was the bottleneck in the system, but for a game like apex legend it still got me to 200-240 fps at ultra settings (HOWEVER, effects was set to low. mostly for game play advantage)

In my old system using a 5800XD, gaming + streaming wasn't as smooth (it worked, just not as good), so i guess the cpu upgrade made some sort of difference




recommend this video. simple things boost ur gaming fps, like changing the power plan to ultimate. simple enough didnt follow everything but its good enuff for my current performance so far. not too sure about disabling certain windows services so i didn't.

Just realised on latest idealtech price list, 9800X3D is now @ 1999 instead of 2399 from last month

Just don't pair it with Asrock mobo...

Asrock & Asus mobo got CPU burn, Giga mobo got bios backdoor, MSI gaming plus mobo got Expo compatibility issue & game crashes, which brand has no problem or isit AMD platform the problem? Maybe Intel Ultramen are better?

Nah, it's higher on AROCK compared to other brands.
Heck, even non-X3D 9000 series are dying on Asrock mobos.
Definitely Asrock bios tuning is problematic on 9000 series.

Sometimes, the culprit is the Ram issue..

https://www.xda-developers.com/ryzen-memory...oes-arrow-lake/

Asrock higher on current case. CPU burn happen earlier this year more frequent on Asus mobo.

All of them at sometime have problems.

Also Jayz2cent found certain SSD will brick with certain Agesa bios version on MSI mobo.

Delidded my Ryzen 9950X3D and I'm quite satisfied with the results. Before the delid, the CPU would hit over 80°C+ during Cinebench runs. After delidding, it's now staying around the mid-60s，quite a big improvement.

With those thermalgrizzly stuff Im surprised you didnt go with Conductonaut instead of silver king

Yep, Reddit is not source of tech knowledge, just like LYN here, unless cited with source
when you need good source info, benchmark ect, Techpowerup, Guru3D, most tech site,
info from reddit or whatever forumer comment can be taken with truck of salts

7800x3d was roughly around RM1,599 (tray).

I am assuming 1999 is a tray version?

With that sort of price difference, i would have gone for the 9800x3d. Only reason i didn't because it was 2.4k+ last i checked (and that was for a tray which is the cheapest). maybe because now is around sales time, so got some good deals thx for sharing.

anyway the 7800x3d for me for 1440p gaming works for me, so not too fussed i missed out. just a shame though


Temperature wise for the 7800x3d after using for the past few month,

82.5c MAX ( when i stress test with OCCT and cinebench at most i saw it capped at 85c)

48.9c MIN

57.5c AVG


I use

- fractal torrent pc case default fans that came with case. did not add extras
- Frzn A720 cpu cooler (scored well in the cpu fan cooler round up for 2025)
- the thermal paste that came with the cpu cooler

I also set a thermal limit in bios to max out at 85c

also PBO under clock all cores to negative 20 (this is stable for me. But when i tested negative 30 will crash). Under clocking improves performance and lowers temps. So no reason not to do it.

I also adjusted the fans in bios, by adjusting the curves. At low temps, lower fan speed, at higher temps, crank up the fan rpm. I balance quiet and cooling. Takes a bit of tinkering to get the right balance. Results based on my stats seem satisfactory to me.

mid 60s during cinebench stress test? thats impressive

but honestly if its under 85c during stress test, should be fine? It's only at above that and for prolong period would it be bad for cpu right? but still cooler temps always welcome
