all my7950x's are at 100% 24/7. Check here for any differences you see, but they are all crunching,.


I just noticed that may not filter by me. Oh well....
I'll take your word for it since that requires me to make an account. Mine will only be running 6-12 hours a day at 100%. If yours does 24/7 then mine will be okay. Short of that it'll smart throttle if something goes amiss.

Some info on AM5 with different coolers. This is from the 7000 series launch

And this from the 7950X3D launch.

Both videos compare performance of the same chip with different coolers, both AIO and air.

My waterblock finally arrived. I haven't even had time to unbox it and check it to make sure everything is intact. I need a new case. I posted a thread in the cases & cooling section but I didn't get a whole lot of feedback there. Basically, I'm (sort of) copying Det0x's build because I have the same rad, motherboard, and waterblock he does. I don't even know what case he has, but I do plan on changing my setup from the 3900X.

The 3900X is in a Thor v2. The tubing goes out the back to the external rad (MO-RA3). I have two D5 Varios, one before the rad and one after, to overcome the massive pressure drop of the MO-RA3. It works well. But I'm tired of the Thor v2 and I want/need a case with a proper USB 3.2 type c 2x2 connector on the front panel. My board (Asus Hero) has a header for it. Not sure if I'll ever need the 20 Gbps as opposed to a "normal" USB 3.2 type c gen 2 connector's 10 Gbps but hey, my board supports it, so why not use it? Plus the Thor v2 is unnecessarily huge for an external rad. I just need a case that:

1). Supports EATX
2). Is long enough for my waterblocked 7900XTX Merc 310 Speedster (gotta measure the block; the card's probably going to be shorter without the default air cooler on it)
3). Has a USB 3.2 Type c 2x2 connector on the front panel
4). Preferably has enough front/top fans to keep my RAM cool so I don't have to rig up extra fans on zip ties to blow directly down on the RAM (or set up a desk fan like in the old days, ha ha)

According to pcpartpicker, those criteria leave me with a very short list of cases. That makes me sad. Alternatively I could get a front panel adapter to add USB 3.2 Type C 2x2 connectivity, but I'll have to shop carefully and that may interfere with some fans.

Jayztwocents just did a review on the Antec Performance 1. Said he really liked it and was able to just about anything inside. Not sure on the 2x2 connector though.

Sadly it only has a standard 10 Gbps type c port. 20 Gbps ports are kind of niche. I'll have to look at Amazon and see if there's a suitable adapter I can put into a bay. Some of those things are so cheap-looking, though, and reviews on Amazon can't really be trusted anymore.

edit: Amazon has a rear panel adapter, but not a front panel one? How backwards is that?

Drop E-ATX requirement and you could give this a home:

Picked up a 4090FE finally, so my build is done.

The 4090 is much quieter than my 3090. Oddly enough the chipset fan is not kicking on as much as well.

I'm just gonna come out and say it. Even though it would use another 100 watts or so I wish I had gone Intel.

Issues I am having on this AM5 platform:

  • Insanely long boot times vs my old 3770k rig which was nearly instant on a dinosaur ssd. I feel like I am back on my old Pentium 133 rig with a spinning drive.
  • Applying any setting in Ryzen Master such as game mode to disable one CCD (no overclocks of any kind applied) so I don't have issue below casues failed reboots and ends up with me resetting bios and uninstalling Ryzen Master every time.
  • DLSS is essentially unuseable in any game unless I use Ryzen Master to enter game mode as its a stuttering *** show at least in any game I have tried including the Witcher 3 and CyberPunk 2077. If both CCDs are enabled its unplayable. Even if I set process affinity for the game process to just 3d cores.

Did you see the latest Jayztwocents rant video, with all of the cpus laid out? He lets slip a tip that you need to do a FRESH install of Windows, if you install an X3D CPU, otherwise things will be really screwed up.

I did a brand new install of windows 11 as I was on win 10 prior. The core parking and core selection is working as intended, but even when the game is running on the 3d cores if dlss and possibly frame generation is enabled it just does not work. As long as I don't use those features I get no stuttering. If I disable the 2nd CCD I can use them without issue. But with reboots taking this long and the crashing that results when using Ryzen Master I am looking at over 5 minutes to switch just once and I can't do that multiple times a day (unless of course I just leave it in gaming mode and admit I was stupid to purchase the 7950x3d instead of waiting for the 7800x3d or going intel.)

who is the guy who was asking about the low end jedec speed ram the other day? he made a few posts on here but I don't remember his handle. If someone knows who I'm talking about please tag them.

I didn't do this (and would not have even gotten the CPU otherwise, as it's a massive amount of work) and haven't seen any problems aside from the long boot time, which is mainly with the POST. You have to just prepare windows for the migration properly.

I think the 7950X3D has extra issues that can be avoided with the 7800X3D though, and in general boot times have gotten longer in the last 10 years. I saw a big increase in boot times going from 4790K/Z97 to 10700K/Z490.

Jayz latest rants. He has some nuggets regarding AM5, like, do a fresh format when adding an X3D CPU (doesn't apply to Linux, Mark).
He mentions that he had would have to reinstall windows as a means to get a 7800X3D to work after using a 7950X3D. Steve of GamersNexus said the same thing. Even after uninstalling the AMD chipset X3D driver they say half the cores were still parking on the 7800X3D. They too fixed it with a Windows reinstall.

I can tell you that is not needed. What appears to happen is that either the AMD chipset driver or Microsoft Game Bar sets the core parking min cores for the Windows Performance Options profile. Uninstalling the chipset driver leaves the setting behind.

I was able to control the parking behavior in my "Ultimate Performance" profile by downloading ParkControl and enabling "Show park settings in Windows Power Options".



I can then control it in Power Options. The parking algorithm is disabled when set to 100% as outlined by Microsoft here,

I am having a very odd issue(s) with a 7950x3d build

GPU is a 7900xtx carried over from my previous 5950x build. PSU, cables, and full custom water cooling loop stuff all carried over as well.

SSD (990 pro - updated firmware), RAM (TForce 32gb 6000MT), MB (Asus x670e Prime Pro - updated bios) are all new.

I spent all day yesterday swapping in the new parts and everything worked fine with DOCP II and PBO enabled with -15 curve optimizer all core. It was working fine this evening as well and I updated chipset drivers, did some additional windows updates, and started playing with per core curve offsets. Was getting some BSODs / boot failures so I started backing off on the offsets until it was basically -15 on everything except two cores which were -20. Seemed fine and was installing a game when the system just clicked (instant off plus click sound) off. Assumed it was undervolt instability so backed that off, still wouldn't boot. Started lowering RAM speeds, still wouldnt boot. Set BIOS to load optimized defaults, still no boot. Cleared CMOS, etc, no luck.

During this time it seemed to POST fine (sequence of LEDs on motherboard indicated success) and start loading into windows but it would restart every time you would expect to see the windows login screen.

I could get to the windows recovery menu but the repair options didn't do anything. Wouldn't boot into safe mode. I eventually got into Windows via the install on the SSD from my previous system which I had put in another M.2 slot. The 990 Pro was visible in Windows and writeable as well. I was doing some troubleshooting and the system clicked off again. Got into windows again on the old SSD and before I could check windows event viewer it clicked off again.

Then for about 30 mins I couldnt even get into the old Windows install until I was writing this post and managed to get in again. Didn't change anything in the interim except power cycle a bunch of times. New drive still showed up but the moment I double clicked on it to open it, the system clicked off and restarted. Might be a coincidence because I booted into old Windows again and did the same thing without an issue. Downloaded Samsung Magician and did a Diagnostic test which indicated no issues. Got as far as doing 2/3 of a Timespy run as well which had more stuttering than normal but otherwise seemed fine, then in the middle of the second graphics test the framerate cratered and the system clicked off again. Clicked off twice in a row after restarting before getting to the Asus splash screen.

Nothing seems physically out of place. Cables well seated, no leaks in the loop, nothing looks especially hot in hwinfo. I think I burned myself slightly on the heatsink for the 990 Pro but it reports as 54-59C in hwinfo. Nothing else in the case feels remotely warm.

The saga continues as I've been writing this and I attempted a Windows Reset which allowed me to get back into windows on the 990Pro. Reinstalled Adrenaline and Far Cry 5 (SSD got up to 70C during validation step where Steam indicated it was reading at 700MB/s). Game seems to run as expected and the system even survived a reboot.

Any ideas what the heck happened / is happening? So many symptoms, some point to hw others point to sw. Maybe a hw issue borked my Windows install? I'm glad I am able to go to bed with a working PC but I am very confused and still worried.

Oh one other symptom is that sometimes the bios wouldn't detect either SSD after several failures in a row. A power cycle would get rid of that, no idea if it matters.

it's possible. One of the youtubers the one that's a fair bit wide with silver hair, Jay i think had a similar issue of being able to boot with crashes and lockups, and then booting into the nothing ether of a black screen. he narrowed it down to psu, mobo, ram or cpu. I didn't catch the end but from what I gather now it was the ram slots causing trouble on a new board. this seems to be an issue with amd boards recently and I'm not sure why. does the x670 spec use a unique ram topology compared to Z690/790?
