AMD Ryzen 9 9950X3D Performance, Overclocking and Cooling Thread

CMDR Thadian Sparhawk said:
I was on a 13900K /6400 M/T ram prior to switching to the 9950X3D/670E. So far, not really seeing any overall differences in gaming at all. If anything, I've lost memory performance having to go to 6000M/T, and AMD's nVme raid is pure garbage compared with Intel VME. Forced to use Windows Storage Spaces. Lost performance there too. Memory controllers on Zen 4 and Zen 5 desktop products are trash, and its neigh impossible to find a motherboard that has a decent configuration of PCIe lanes that don't downgrade or get disabled. So far only the ROG Strix-A 670E seemed to fit the bill. I didn't get Zen 4 Threadripper because of the performance regressions in single threading and how poor it scored overall in gaming. I suspect Zen 5 TR isn't going to be much better. So yeah, not at all impressed with the current situation with AMD, and of course Arrow Lake's regressions are quite bad too.

I'm not at all impressed with Intel. Raptor Lake performance regressions from longevity fixes because, you know, they'll die otherwise. EOL socket platform. Arrow Lake limited CPU platform upgrade path. AM5 will have at least Zen 6 as the last upgrade, and maybe a new memory controller...so three years out until EOL for AM5. TBH, if you had a 13900K and were fine with perf (and comfortable with the fixes that Intel came out with), you'd probably have been better off putting the resources into a GPU. But enthusiasts will be enthusiasts =P
 
I just came in here to say that 9950X3D has been dope af thus far. I am loving the faster shader compilation and snappier windows. Rest it is not a massive upgrade from 9800X3D but I didn't expect that. I only got it for shader compilation as that is my only use case.

What makes you think that the introduction of am6 will be eol for am5?

They’re still releasing new CPUs for am4 which is near 9 years old. So even if you have a current AM5 mobo/ram combo you’ll be able to buy a warrantied new am5 chip in min 4 years with a 3 year warranty. 2032 sounds like a reasonable point from today to have full backed manufacturer support, or at very least be in the market for a full system upgrade.
 
It actually looks like rumor mill wise the next CPUs for AM5 will be more cores per CCD with even higher clock speeds. Actually, looking forward to what might be a drop-in upgrade for my 9950X3D (not that it will be needed).
 
I really want to keep this CPU for more than a year. I am getting a bit frustrated by the incremental upgrades tbh.

I'm not talking about new CPU's within a generation. I'm talking from generation to a new generation. You're right, AM4 is still great and getting CPU's, but not beyond Zen 3 and not massive upgrades beyond mild x3d parts. Zen 6 will be the third gen on AM5. I hope it extends to Zen 7 and beyond, but I doubt it from the AM4 example. I'm sure AM5 will be active for a while like AM4, unlike Intel.
 
Got bored, decided to tweak this 9950X3D setup some more... decided to go from 6400MT/s CL30 on the Ram 1:1 to 6200MT/s CL28 at 1:1, except I raised FCLK to 2200Mhz. Got roughly the same bandwidth, but lower latency. I did not use latency killer for this test as it does eat some minor CPU performance, but this latency is lower than what I had previously with latency killer off as well. Overall, things have improved. Running OCCT now at 24 thread count while running some other items and listening to music to listen for any FCLK error correction. So far, stable and good! SoC is at 1.27V. Had to raise Ram voltage from 1.4V to 1.45V for CL28 @ 6200MT/s.

Can you post your CB24 or CPU-Z bench scores?
Click to expand...
Sure... quick run for you. Not my best score ever for ST (891 was my best), but I really just do not feel like closing everything and whatnot for the test (as it is fairly task sensitive). Most the changes I made can be seen in AIDA64, I do not actually expect much (if anything) for CPU performance gaming at 4K... lol. Although I might do some tests and note if the 1% lows changed at all.

I mostly did the changes because I just love tweaking hardware to see what it can do and if I notice any changes. I did not exactly buy all these parts to set and forget, I half bought them all to tinker as well and enjoy the chase. :)

So I am starting to think my cooler is not up to the task or I did not mount it well. I'm using a 360 closed loop cooler and under some scenarios I see the temp spike to 95 C. normally during gaming its around 81c or 80c. Granted my house is kept about 81f degrees indoors as it is summer. I read reviews about multi core workloads around 75C. I don't think I'm ever being throttled, but I'm just curious.

Ambient temperature will have an effect. Test at night or very early morning if it gets down into the 70s to see.

But 81C while gaming does sound high, unless it's building shaders.

the building shaders is what hits 95C The CPU and GPU run almost identical at 80 or 81c, but the GPU pulls near 600 watts. That is why I am concerned with the CPU reporting so hot.

Take the side of the case off as an interim test. If the temps drop a good bit, you need better airflow in the case. If not, repaste and check the mount as you've stated.

If none of that helps, perhaps your AIO's pump is going out? They can get gummed up with time.
 
The only way I can get my 9950X3D to even hit 90C is small FFT on P95. Gaming its 60C or below, shader compile maybe 70C range. Cinebench about 81C.

I think u have something going on with the AIO or Airflow in the case. My gaming room can hit 80F in this summer heat and its has never been so high gaming. Basically, it goes from mid 50C range to low 60C range if my game room hits 80F. I do not think ambient temperature is your issue.

Dang. Maybe I will remove the cooler and redo the thermal paste this weekend. I tried really hard when I swapped from the 7950x3d to the 9950x3d, but something must have gone wrong.
 
For a closed loop your temps are pretty bad. Even with my Corsair AIO which was 8 years old, I wasn’t having such temps.

My new Arctic AIO is much better. I saw temps drop by about 5-10 C. In most gaming I get about 60-65 C now and only during shader compile it hovers between 70-75 C. Cinebench highest I see for 10 mins is 78 C. Mostly 75 C. There are only extremely rare situations in some game compilations where I saw it break 80 C.
 
That sounds high considering I can't hit 95c outside of synthetic stress tests with a puny Peerless Assassin 120, and even then it's only brief spikes because the 200w limit at stock settings is quite reasonable. I could probably increase my case fans' speed and never hit 95c, but that gets too noisy for me.

I "only" have a 450w GPU, but still, that can't be the reason why unless your case has a serious airflow deficiency.
 
I did install Fan Control as I think my case fans were not moving enough air. I think its helping some.

Just out curiosity, anyone test Helldivers 2 temps? Seems to be a heavy on my CPU. I'm getting 71-75c on a NHD15 in ambient 23c. A know, I narrow case as a reference. Cheers.
 
If rumors about the next AM5 CPUs are correct and we get 12 core CCDs, with X3D as well, that will be nice!
 
AM5 is fine for that and cheaper.

SMP systems with large amounts of ram (4-8TB per socket) come in handy, the more cores the better.

Now if Intel re-ignited a next gen X point product line, six gen PCI-E and beyond with capacities over 100TB, that would be incredible.

Only if it could do double the pcie lanes too.

The number of pics Lanes are ok it's just only ASRock and MSI did it right how they take the lanes form other stuff then the GPU. Asus and gigabyte did the 870 line up badly where if you ues more then 2-3 nvm your x8 on the GPU.

MSI has some boards which disable USB4 if too many NVME drives are installed.

Hilariously, USB4 is supposed to be one of the big new features for X870.

Its too bad Asrock's boards are killing CPUs. I generally love their choices on features. Their ITX boards have the best layouts. And their pricing is good.
 
I think MSI tomahawk x870e is the best board out there. Other option would be the carbon or ti edge.

Asrock taichi lite and taichi are supposed to be very good but yeah I don’t trust them to not kill the CPU yet. Their own person wasn’t sure if the issue was fixed when GN met them a couple of months back. So I won’t take a chance.

If you don’t mind usb 4 then MSI tomahawk x670e is a great board that I am using right now.
 
Are there any boards that support bifurcation of a 16x or 8x slot down to 4x/4x/4x/4x or 2x/2x/2x/2x? I have a NVME raid card I'd like to use and would also be fine with running the GPU in an 8x slot.

I have a x870e tomahawk It actually just goes to 2x on usb4 and nvme if you ues nvme2 but you can force 4x on the nvme. It's definitely better then x8 on the GPU as how many people ues usb4? So on the MSI you can run 2 gen 5x4 and 2 gen 4x4. Sounds a lot more useful then having a 40g USB port for my phone

Are you guys forgetting x8 GPU has like zero penalty?
 
I'm sure there are use cases on why people use so many nvme slots and whatnot, but I am able to use PCIe 5.0 full x16 on my 5090, with 1 nvme on PCIe 5.0 x4, 1 nvme on PCIe (chipset), still have an AE-7 in my last PCIe slot (also chipset) and using 2 SATA slots as well, and USB 4.0 and WiFi 7 are still perfectly intact. You just need to ensure you connect your peripherals to the right slots is all. Granted, if I had more nvme's, then I might start to have issues... but 2 nvme drives is more than enough with a large HDD for backups and files I do not need fast access to.
 
Yeah, the 800 series was a downgrade for me due to the PCIE lane distribution / sharing - they had to pull somewhere for USB4. X670E seems better overall from that perspective - all four M.2 slots occupied and not sharing with the GPU or other PCIE slots, x16 for the GPU, and an x4 electrical bottom slot for a RAID card.

The only thing that I'd have liked on this $369 (on sale) MSI MAG X670E ACE is a regular DP or HDMI port vs the USB 3.2 gen2 10gbps DP port - I'm having a hell of a time finding a cable or adapter that passes Dolby Atmos properly.

Maybe the 800 to 1000 dollar boards don't have those same PCIE lanes distribution limitations, but I don't have that much money to throw at this hobby.
 
Yeah, my old Asrock X670E Steel Legend does as well, but I swapped that out due to Asrock boards having a high 9000X3D failure rate when this MSI board went on sale a few weeks ago. Sadly, it was the only AM5 in stock that has the connectivity that I need at a price that I was willing to pay.

Just got rid of the same board! X870E-E for me but open box at MC for $250.
 
I am heading to MC tomorrow. I will be rummaging through their open box crap for some deals.
Problem is I already got all the deals I wanted on Amazon - Vanguard 5090 for 2759 (no tax), K70 Pro RGB Keyboard for 114 (no tax and 16$ ship to UAE), Samsung 990 Pro 4 TB SSD for 183 (no tax)...
Not sure if I really want anything anymore.

That will be fun. Spoiler alert - you can do it all from your hotel tonight and reserve it so you don’t miss out! My MC usually posts new open box stuff at midnight in case you’re out late and want to snag the latest returned cards, etc. If nothing else get some thermal paste and some MC-branded USB drives. Have fun! :)
