Question Zen 4 builders thread

[Markfw]

I know its early, but as someone pointed out, I better get my ram now before the scalpers are all over it.

To go with a 7950x, what do you think of this ram:

What jack on the back does he have the headphones plugged into? Are they just headphones or are they combo headphone/microphone?

Mark, make sure you aren’t plugged into line out/speaker out. That is for powered speakers.

That's where I was going with my previous comment. According to the manual for the Motherboard you should be connected to the green rear audio jack for headphones.

Any recommended earbuds that might work better ?

No complaints for me on my Thinkpad with these: https://www.newegg.com/p/0TH-003M-004D3

They are not crazy loud but good enough.

 

[Captante]

Thanks for this, but when he installed the app, there is no ohms setting slider. And nothing in the app fixes the issue.

Any more ideas ? Any recommended earbuds that might work better ?

Bear in mind that not all "onboard" motherboard sound is created equal.

Additionally the Creative sound-card I referenced earlier has a REAL high-impedance headphone amp onboard as opposed to the vast majority of "onboard" chips, along with most bargain-basement add-in sound cards.

My Asus B550 board for example has a relatively high-end Realtek audio chip but the Audigy 5 RX was an obvious improvement over it with powered speakers and was night vs day with high-fidelity headphones. (with onboard they sounded like a clock-radio and got about 1/4 as loud)

yes, in the green jack. They worked on the cheapest Zen 1 motherboard, but not on this Zen 4 board.

Some boards will have a black jack specifically for quality headphones or non-powered speakers.

Bear in mind the "cheapest Zen 1 MB" may have had sufficient power to "push" the headphones while the new "improved" Zen 4 may not. Either that or the jack and/or the chip itself may have been damaged by "hot" plugging/unplugging powered speakers which is depressingly easy to do. (and is also capable of ruining your speakers as a bonus)

The easiest (not cheapest!) solution is to go with an external USB sound card with it's own DAC and legit onboard power. Make the right choice and "fidelity" should also improve w/an external DAC since it bypasses all MOST of the electrical "noise" inside the PC case.

Thanks ! I ordered one. This has to be the solution !

Inquiring minds want to know - did it work?

Yes ! He said he had a bunch of windows and device volume changes to make, but thats it. Thanks !

Had my first BSOD yesterday, when I shut off the computer and the boot into windows was really slow afterwards. But now everything seems normal.

I booted my zen 4 box last night for it to not initialize and recognize my M.2 drive. Booted straight to UEFI. Damndest thing, a reboot and it worked fine.

I'll chalk it up to the randomness of the universe unless a pattern emerges.

Another interesting article about ECC support seeming to work in Linux with consumer AM5 motherboards (and specific AGESA versions).

ECC RAM on AMD Ryzen 7000 desktop CPUs :: sunshowers

Getting ECC memory working on desktop CPUs.

sunshowers.io

I guess I'll give it another shot when I upgrade to Zen 5. The old 7950X (at maybe 105W) would make a good enough server chip.

ECC was supported at release then disabled via agesa update. It was re-enabled in 1.0.0.5c, and as far as I am aware it will enable on all boards. Whether you can get error reporting or injection working is the wildcard, and as far as I know asus is the only brand that does handle both of those.

Ok, I got the 7800X3D setup as follows:

Cooled with Corsair H115i, idle under 40*C, load around 70*C.

Might switch back to tower air cooler at some point.

What's the perf improvement vs. stock settings?

 

[Golgatha]

I have a MSI PRO B650-P WIFI. I was using manual voltages for the CPU prior to updating the BIOS. After flashing to the latest (7D78v1D/AGESA 1.1.8.0) BIOS, now if I set manual voltages my CPU runs locked at 10% of base clock or 0.45Ghz for the 7700X. Anyone else experience anything like this?

As far as other settings, EXPOII, setting thermal throttle to 90°C manually, and curve to -15 on all cores; those settings all work without any weird issues. Leaving with CPU at Auto for voltages with all the other settings set manually works well enough for now and there's no difference in performance in terms of boost clocks, but it would be nice to dial back the voltages so it would run a bit cooler like before the BIOS update.

Edit: Both of my ASUS motherboards work fine with manual voltage settings after updating to AGESA 1.1.7.0 patch A with their respective BIOS files, so I'm wondering if this is an AGESA version bug.

 

[B-Riz]

What's the perf improvement vs. stock settings?

Lol, I didn't run any tests, just wanted to get temps dropped

I still get the same FPS avg, 1% and .1% in games, still boosts to 5 Ghz, etc.

Downgrade to the version immediately before this one and see what happens?

I did not run any stock tests, but did run my "tuned" settings vs setting temp limit at 80*C, after reading this post:

Sadly, this still doesn't fix the scheduling issues that occur if you enable PBO on a 7950X3D.

The specific issue I have been testing as AGESA and chipset driver updates come out is that a singlethread benchmark, specifically cinebench, will run that thread appropriately on the two fastest cores of the high frequency CCD when everything is at default. Enabling PBO in any capacity whatsoever (even just turning it from "auto" to "enabled" and leaving everything else untouched) causes it to schedule that thread incorrectly. It used to just kind of round robin jump the thread across every single core. Now it schedules it onto the V$ CCD's best cores.

I still don't comprehend why this is even an issue - Scheduling works fine at stock, but enabling PBO causes it to go haywire.

https://www.reddit.com/r/Amd/comments/123o13s/7950x3d_short_review_from_actual_home_user_pbo

To make things super easy, you can remove that V-Cache driver and turn off Game Mode, then go in your BIOS and set CCPC to prefer frequency cores. Now every program (aside from maybe a couple drivers) will all default run on CCD1 leaving CCD0 completely empty for gaming. Now just use Process Lasso to set CPU Sets or Affinity masking to CCD0 for games, and you have a pitch perfect gaming and streaming single PC setup.

Could that help?
