5950x underperforming, I believe

Smettuh · 22 Dec 2020 at 23:54

Hi all,

I don't expect to match the top results but I can't help myself and be bothered with my Cinebench R20 results and the core clocks I'm getting. They are too far off I believe, basically I am getting a MT score of a 3950x.

Clean install, all latest drivers installed.

My system specs:

5950x
ROG Strix X570-E Gaming
2 x 16 GB CL16 16-16-36
Arctic 360mm AIO cooler (reapplied this one to be sure)
980 Pro SSD
Slowish GPU

Cinebench R20 MT results: 9250 - 9350
All core clock: 3675 - 3700 mhz
Core voltages: 0.994V to 1.000V
Temps: 60-65 degrees (standard fan curves)
PPT 89% of 142W
CPU Power 94W

Also my single core clocks never reach the advertised 4900mhz. 4825mhz is the max during a long single core Cinebench run.

Don't want to use PBO or OC, I want out of the box performance basically.

Tried also with max cooling, temps remain below 60 degrees then. Clocks 25mhz higher (same for single core), Cinebench score more consistently hovering 9350.

Thanks for helping.

I had the same thing when I put in my "up to 4.6ghz" 3900x and my motherboard blessed me with 4.2. There was some thing at the time about setting your CPU voltage to "normal" from "auto" in the bios that helped a lot of people.

Photolysis · 23 Dec 2020 at 01:36

In your one screenshot you can see one core boosted to 4.875GHz, which is 25MHz off specification.

So a couple of things I notice compared to mine (which is constrained by temps, so I'm going to add more case fans and redo the paste with arctic silver). I'm currently running stock, with PBO disabled.

If I look at the max voltage on mine, I can see it peaks at 1.5V.

Even having the machine running more or less idle for 10 minutes, with web browsing and background tasks, 8 cores have already boosted above 4.9GHz at some point.

What power supply are you running, how much headroom have you got?

Grim5 · 23 Dec 2020 at 05:48

Your performance is a little low. Running the latest bios? Windows in balanced or performance power plan? If you have ryzen master make sure it's not in eco mode

your cinebench score is around the higher end of stock 3950x CPUs and about 8% under the average stock 5950x.

Your all core clocks are low, the 5950x stock should be holding 3.8 to 3.9ghz.

Your power draw a bit low too, running Cinebench multithread you should see 120w on the stock 5950x but your power draw is 20% under

Smettuh · 23 Dec 2020 at 08:08

Power supply is the AX760i (platinum ce)
Power draw during the Cinebench R20 MT run below, quite some headroom left.
I run a GTX970, ordered an Asus RTX3080 on day one, still nothing ;-)

.

I'm running the latest BIOS version on the ASUS website:
Version 3001
2020/12/08 19.97 MBytes
ROG STRIX X570-E GAMING BIOS 3001
"1.New CPU support
2.Add a ReSize BAR shortcut for AMD SAM support

Installed the latest chipset drivers: amd_chipset_software_2.10.13.408

Power plan is set to Balanced, but switching to high performance doesn't change anything.

Ryzen Master is set to the default control mode, no auto oc, pbo or eco mode on one of the profiles.

Some BIOS settings, only DOCP is loaded, rest is default.
Idle temps are high, but ok based on the voltage I'd say.
My case is the Meshify S2 with plenty of airflow (all Noctua case fans)

Cpu has degraded. Seems to be a lot of this going around. Bad quality silicon.

Doug2507 · 23 Dec 2020 at 08:43

Odd. Your cpu core voltage and VID don't really move from 1v yet you're drawing a massive 120w+ avg for package. Your minimum clocks should be dropping below 3.7 as well.

Add to that your TDC/EDC are fully loaded and you've got really high memory usage.

Below shot is a 5950x I put in yesterday after r20 single and multi runs for comparison on power / current draw.

I don't know what the root cause is but I'd be tempted to do a clean install of Windows. What chip did you run before on this win install?

Grim5 · 23 Dec 2020 at 10:30

I would try doing PBO with auto settings to see if it improves and if so by how much. Failing that, using a clean install of windows with nothing but cinebench and HWinfo installed and then test your cpu is another good idea. If that fails, consider RMA

Keep in mind that I started recording hwinfo at the start of a MT Cinebench R20 run and I took a screenshot during the run. So that would explain the package power values that otherwise match your maximum I think?

This is already a fresh install btw, I had a 3700x before with a low end motherboard and RAM but selling them.
I did run cinebench early without many services installed and my score was a bit higher but not close to my expectations basically.
PBO results: 10800 +-
PBO results seems to be the result that I should get without PBO and with decent power and temperatures.

So rather high temperatures, hereby the HWinfo results from start to end (MT run 2 min) below.
Not sure if my AIO cooling is adequate. Should be one of the better ones for Ryzen. Did use Arctic freezer cooling compound from a few years ago (approx 4 years) but looked perfect.
Did already try to reapply.

Doug2507 · 23 Dec 2020 at 14:49

Wow, your temps are mental. Something not right with the cooling solution / mount!

DoneADougalOnSofa · 23 Dec 2020 at 14:55

Is it not downclocking correctly?
I got caught out once by the slider in Windows' power options. If you slide it all the way to the right, your CPU won't downclock. This is unaffected by 'minimum processor state' in profile settings.
Keep it at the middle setting (Better performance) and it'll wind down below 3.6GHz... hopefully

Smettuh · 23 Dec 2020 at 16:31

This is with PBO enabled during an MT Cinebench run, I don't want them to downclock.
I think these clockspeeds are low for PBO enabled.
Seems to be related to my temperatures, who knows even my bad results without PBO are.
I will take pictures when I remove my Arctic Freezer 360 so you can determine if it was correctly mounted perhaps.

chanjy · 23 Dec 2020 at 17:22

Have you checked your RAM timings and sub timings against the Ryzen DRAM calculator? Seems quite sensitive to these little things

Smettuh · 23 Dec 2020 at 18:53

Reapplied the arctic freezer for a 3rd time, damn that cooler is a pain to install solo.
I immediately heard the difference, my fans are basically silent now while doing some casual work.

Results are still on the low end but this is with some minor services running.
Cinebench R20 MT 9550. Still low voltage (not more than 1.000V) but temps are hovering 55 degrees now.
PBO new score is 11020: Is this acceptable or also on the low end? All core clock was 4.4ghz with temps hovering 80-85 degrees.

I haven't checked the Ryzen DRM calculator, will try now.

Doug2507 · 23 Dec 2020 at 19:00

Still seems pretty toasty tbh but within AMD spec...

Anthos · 23 Dec 2020 at 19:00

I tried mine now just out of curiosity. Cinebench r20, 9399 (2nd run 9441) all stock. Max boost I've seen was I think 4825 in R20 and in single core in R23 4850. (edit as I was writing this and R23 was still ongoing I did see that since one of them boosted to 4950.. at some point)

Smettuh · 23 Dec 2020 at 19:15

Checked a few PBO results from reviewers etc and my PBO score seems to be better in line with the majority which makes me think it's BIOS related.

Temps indeed not very good when using PBO, could be a few reasons.
- Thanks to GamersNexus I'm running my radiator in Pull on top (should give better cpu temps then push on top) and ALL case fans exhausting.
Radiator on top because I can't install it 'the right' way in the front. See screenshot below.

- I probably do not have a great chip

- Case filters not removed

snips86x · 23 Dec 2020 at 19:33

Your front case fans are the wrong way round.

Just looking at your pic there, rad fans at top should be reversed and front fans reversed also, cold air in from the front sucked up through the rad and out. rear fan is correct.

Smettuh · 23 Dec 2020 at 20:06

That's how it is usually done yes. However ....

After all the hype around incorrect radiator placement versus the pump (https://www.youtube.com/watch?v=BbGomv195sk&t=860s&ab_channel=GamersNexus) it was stated that if you cannot mount your radiator in the front with the tubes down that mounting it on top is better. In addition it's more optimal in that scenario for a pull config (just like pull in the front is better for your cpu temps).
You pull ambient temp air into your rad, not temps of your case like you would in push. The fact that hot air rises is basically irrelevant with case fans, it's a minimal difference.

I believe Steve in this regard, I could do a comparison this week
