My mistake. Is typo. But that is beside the point I was making.

I was meaning the x870 mobos with the 9800x3d u can Google there are news stories about this right now. Both Mobo and AMD pointing finger at each other.😅

Didn't hear much issue for 7800x3d so went with that since it cost less and paired better for graphic card without overspend. Minus the recent news dilemma, Donno know what's going on there 😬


Jus an update on crappy MSI x870 tomahawk wifi audio. For myself I'm using an edifier qr65 speaker. When I plug it on using isb, it uses it's own dac internally in the speaker. So should avoid whatever potential issue in regards to crappy MSI audio realtek chip dac included.

After I watch hardware unboxed, he explains what is different between the chipsets. Based on price n features I think I r right. But bit late. Anyway it was in my budget so no problem. But like I said for my system spec maybe the b650 would have been the more value buy

*Update

B650 no pcie5.0? So I guess unless I need that b650 is fine 😅

PCIE Gen5 for GPU is overrated. Even 5090 doesnt saturate Gen4 slot max capacity. By the time a monster GPU will need Gen5 speeds, AM5 will have long been EOL ady. Maybe will see in AM6 or AM7 lah.

It doesn't? Then like that no point then. If later need pcie5 , that time will can buy mobo. If buy b650 now can go cheap.

Not sure about USBs but I sus it's still on the slower side for b650? But for the x870 tomahawk I got it has some fast usb4. Where another Mobo the x870 carbon, it added everything usb4 as if ur mouse and keyboard need that...

Waste of money 😅

I think they said the newer and platform is 2038? Something about more coees and threads. My question is, how much? And how much power will it use 😬

For my system right now,.just upgrading graphics card will boost fps. But right I'm pretty ok with my gaming so I don't feel like upgrading just yet.

A 5070ti coat rm 3.5 to 4k 😬

Don't even bother 5900 those go for 11-12k 🤢

I like many others went with a Radeon graphics card cauz is cheaper. I don't care for ray tracing. I do miss the dlss though since it's better than fsr. That said I can do apex legend at high fps 240 without fsr for rx7800xt

At least for my reco MSI mobo it does up to USB 3.2 Gen 2 10Gbps. USB4 /TB is usually for the highest end. Tho I doubt its usefulness unless your got a USB4 device to connect to

Am on Asrock x870e taichi with 9800x3d (before the news breakout) and everything is still alive

but pay extra attention as it is an eATX (with 30mm longer if I'm not mistaken so double check on your casing size)
Not supposed to fit Fractal North non-XL but somehow it works

Bought it for the price vs VRM but alas couldn't push the RAM to 6400 1:1 (didn't get golden CPU), when got mood / time then only i will try 8000 with 1:2

and I liked the position of the M.2 slot beside ram, so that's where my drive located instead of the typical location under GPU for the better cooling of NVME drive

AMD comments on burning AM5 socket — chipmaker blames motherboard vendors for not following official BIOS guidelines



Seems the issue isn't 100% fixed.

finished upgrading to new am5. works very good, no regret.

to go 4k resolution gaming cost too much. new graphic card required (roughly about 3.5k to 4k for a 5070ti), and maybe a 9800x3d for the extra performance to match the graphic card for 4k (this is 1k extra vs the 7800x3d). And the existing psu need to change as well to match the new graphic card, so that would be about 500-700 or something.

Anyway happy with my upgrade, will test later for apex legends. but general surfing so smooth

i did the pbu tuning by negative -15, seems stable.

Same as Intel 14th Gen CPU burn. Trust AMD as much as you would trust Intels assurance this issue is a mobo problem (its half-half tho).

Naw, at higher reso CPU isnt a dealbreaker as your more GPU limited

at 4K only with 5090 can see a CPU diff


Even at 1440P, you will need 5080/7900XTX to see a diff


You can still hold on for 10800X3D later no problem.

Be aware that beefier GPUS are also a lot bigger and so if next time upgrading please ensure that it can fit in your case w/o being too constricted.

so for a 5070ti a 7800x3d would be good enough is it?




i was testing youtube streaming + gaming using the new upgrade.

got 1440p ultra settings for apex legends, got obs, got the vtuber app running, got obsbot for video cam and music.

Also i forgot, but i was downloading diablo 4 on battlenet so that was saturating my limited internet speed 100 mbps

it still streamed ok.. haha. if u watch the ingame performance thing to the right, the fps is almost 240 fps most of the time. i'll install msi monitor later when free



oo plz like and subscribe, ty

240 FPS is plenty tho most people play shooters (Apex, valorant, fortnite) at lower settings to maximise FPS. Then again also depends your monitor refresh rate and capture card max FPS something.

doing more testing

messed up my setting so when streaming it was more like average 150 fps while streaming. Before i think it was not as accurate because i did not yet setup msi after burner. after i did, i notice some issues. Like the 7800X3D this one max out 100%

Graphic card was like 70-90%

still tweaking settings seeing what works. To be fair i was doing other stuff while gaming, so not the most ideal condition


after googling, found out the RX7800XT can't do HDR streaming (it lacks the encoder feature for that) thats one downside. when i first bought this graphic card, this wasnt a feature i was on the look out for since i didnt have a proper hdr monitor so i didn't care at the time.






at some points in the stream (few times), the screen froze, so i could do anything for a few seconds. So essentially i was a sitting duck in the game look at 4:00 to 4:05 u see it freezes

Notice how the graphic card and cpu utilization at or close to 100%


my obs output streaming settings are

audio - ffmpeg aac.

video encoder: amd hw av1

rate control: hqcbr

bitrate: 9000 kbs

keyframe interval 2s

preset quality

profile main

max b frames 2



ANy suggestions to improve? Mostly how to get the graphic card and cpu utilization to lower slightly? if it was stable at 90% it would be alright. But at 100% i get that weird frozen issue for few sec every now and then. I check obs and it claims no dropped frames. But when playing it's a problem



CPU and GPU, temps are fine.

For CPU i went to bios and did the pbo underclock. Mine is negative 20 which seems stable. When i tried 30 it was ok for a while but i experienced a crash later on in the day, this is why i set from 30 to 20, now seems stable. for those that don't already know, the reason why you do this is to lower the temps for your cpu, and also increase performance. there is nothing to lose to try doing this for amd. Only certain amd mobo chipsets has pbo however. Mines a X870 so it has it. So even when you are low balling for mobo chipset, make sure it at least has pbo feature

I also adjusted the cpu and casing fan speeds to be more aggresive on the temp curve.

Next, in the radeon graphics card tuning settings, i adjust the fan to kick in sooner and more aggresive on temp rise. Might be louder but i honestly dont notice the sound increase for it to be an issue.

Sorry mate, not a streamer so I have zero knowledge to help. Neither am I a Ryzen user so Im not sure if its something to do with it.

You have freezes due to CPU hang when going 100% utilisation. I can have this when doing multi Excels with complex formulas which I suspect due to insufficient RAM. Your case you have to trace why CPU goes 100%, can be RAM throughput or size, can be process spikes, etc.

Also can be instability due to your undervolt, I would try it again at everything stock w/o PBO, then at stock PBO, see if it changes anything, then slowly take smaller steps to undervolt.

undervolt? oo.. thx for the hint, thx

Borderline instability can be hard to catch, I did RAM timing tuning real fine which passed all RAM tests like gila but then was having occasional stutters when play videos, everything else was running normal inc games. I have never come across tuners having such issue but when I change just 1 parameter only (tRAS + 1) it went away. It was thaaattttt borderline.

For your case did you do stability testing when PBO and whatnot?

im transfering stuff so i didnt get a chance to run cinebench for 5 hours yet. so no.

my first crash was with pbu negative 30. it just crash after less than a day once. i just chalked that up to the undervolting for pbo, so i changed to 20. no crashes yet.

surprisingly even when doing the streaming + gaming + file transfer, where the gpu and cpu were maxing out, the only worse thing that happened was that occasional screen freeze for a few seconds. But no crash.

when i am not stressing the system like that, it just plays smooth no issue

Cine isnt the best stressor for CPU. Coupled it with OCCT & Linpack. I would do 2hrs Cine20, 2hrs Cine23, 2hrs Cine24, then OCCT, then the most stressed I ever found Linpack Extreme. Even this only gotten me 99% stability with the only error as I mentioned above.

when i tried occt free it stop after 1 hour though. do i need to buy to make it run longer?

ill try these and report back results later ty

No just run each hr back to back should do. Actually for RAM testing, if within the hr ady got problem is more than enuff.

EDIT: Since yours Ryzen try with AVX512

i got old memtest86. this app any good for ddr5? or no point



*update

anyway after test, seems it can do gaming + youtube streaming + play music. It does almost max out graphic card and cpu though, but not to the point like before where it froze So yeah i think it's fine. average fps about 200. Keep in mind this is when streaming. So when not streaming, i will see 240 fps usually. But it's still quite good fps is still decently high even when streaming regardless. So yes for my new 1440p gaming streaming build, this works fine




one odd thing that happened was the obs preview froze. but when i check youtube it was not frozen. later on the preview worked again. donno why


So anyway if anyone want to make a similar build thats proven to work, this is my parts


AMD 7800X3D


MSI X870 Tomahawk Wifi motherboard (this motherboard the extra pcie is X4 and X1, so make sure this is a non issue before you get this motherboard. The usb dac people is not good, but since i use Edifier QR65 internal DAC in speaker via usb connection, it's a non issue for me. I didn't test if the mobo usb dac is good or not but some reddit posters said a bios or driver update fixed it)


AMD Radeon RX7800XT Sapphire Nitro+ (if you are a new buyer i don't particularly recommend this as there should better options in 2025 for the price. This is just simply what i have for a prior purchase. Didn't feel the need to upgrade my graphic card. It's more than sufficient for 1440p gaming. Refer to youtube stream for the fps while streaming and gaming). the Sapphire nitro+ had the best cooler for this model. Temp was never an issue for this graphic card.


Gigabyte MO27Q2 QD Oled semi glossy 27'' 1440p free sync monitor.



Kingston Fury Beast Black EXPO DDR5 CL30 6000M/T Kit of 2 sticks X 16gb (total 32gb). When buying ram make sure u get the correct part number. The one i got was the KF560C30BBEK2-32 which is in the motherboard QVL. I tested it, it's rock solid for this motherboard. Can do EXPO 6000M/T just fine.

Frzn A720 Cpu cooler
https://www.tomshardware.com/pc-components/...and-a620-review




Fractal Torrent pc Casing (few years ago it was crowned best air cooling case)


Seasonic 750watt Gold Focus+ FX psu (since i am using a RX7800XT, this wattage is more than enough. If you are planning for a 5070ti or something, then you need a 850watt psu or better. Also the newer psus have the new cabling the nvidia graphic card might need). Yes my psu is old but it works, so no reason to replace it. thats how rock solid the seasonic psus are.


edifier qr65
