7800X3D - idle frequency range & temperature questions

[Flogger23m]

Have some questions about the 7800X3D.

1) What is the average idle frequency range supposed to be? I've read it should idle around 4.2-4.8 GHZ, although mine seems to idle in a range around 2.9-4.8 GHz.

Some screen shots from HW Info shortly after a fresh boot at idling. Does it look normal?





2) I have some questions about temperature at load. The CPU seems to run hot. Are these temperature ranges normal and safe?

Ambient temperature: 65F / 18.3C

Cooler: Thermalright Phantom Spirit 120SE

Case: Fractal Design Define S, 2x 140mm intake, 1x 120mm intake, 1x 140mm exhaust and side cover open (but no fan installed).

1 Hour of handbrake, H264 1440P video, Very Slow rendering (more demanding than games):



Games tend to be in the 70-75C range, and the CPU cooler doesn't hit its max RPM of 1500 either. Though when it was warmer (ambient temperatures ~ 73F / 22.7C) the temperatures were higher.

These temperatures seem fine for now, but what worries me is when summer comes around. Ambient temperatures will easily get up to 85F / 29.4C frequently. Is it something to worry about? Seems like once it heats up even games will be pushing it up into the mid to high 80C. Considering the cooler I have, that seems a bit high to me, but wondering if that is normal for the 7800X3Ds.

pretty much a 1:1 copy to my 7800X3D.
3-4Ghz idle, demanding games in the 70s with two different thermalright coolers (PA and BA 120)

Did you hide a bunch of CPU sensors? Idle looks fine. 2-3 digit freq effective clock on two main CPPC cores and 1-2 digit effective on the others is pretty much what I look for at idle for desktop Ryzens, it seems like you're already there.

Idle package power is a little bit on the high side but that's probably because you are running relatively high VSOC (1.25V). I'm about the same as you at 1.2V, and at 1.05V can shave off about 10 watts.

For 21C ambient I haven't broken 80C yet at about the same ~85W with a suboptimal FC140, but there's probably lots of variance in chip temps from sample to sample and also how the chosen board will run the chip.

Have you played around with PBO/Offsets yet? Different CPU (5800x) but I expect the same results in lowering temps, especially with the 3D vcache.

I think something is wrong with your cooling if you are only pulling 85w and hitting the thermal limit.

 

[AusWolf]

Your idle depends on the Windows power setting used. It looks like you're using Balanced with the power slider dragged down, which is the best setting for Ryzen, imo.

Your cooling seems to be scraping the bottom of the barrel with 88 C at 90 W (which is pretty much the max for the 7800X3D in both power and temperature), but still acceptable.

Edit: For reference, mine does 82-83 C at 90 W under a be quiet! Dark Rock 4.

 

[Dragam1337]

Impressive, OP managed to hide nearly all relevant cpu stats in the screenshots he posted...

 

[Flogger23m]

Did you hide a bunch of CPU sensors?

Possibly some are hidden. What values do you need to see?

I've attached some results of around 40 minutes of gaming, CoD MW2, and sitting at idle. Seems like it spiked up to 79C for a bit during gaming. That looks to be all the stuff pertaining to the CPU unless some values are hidden. Motherboard is an ASRock X670E PG Lightening.

Idle package power is a little bit on the high side but that's probably because you are running relatively high VSOC (1.25V). I'm about the same as you at 1.2V, and at 1.05V can shave off about 10 watts.

Should I lower it to V1.2V? I do not recall changing any settings related to that, BIOS are essentially default except for enabling EXPO with the RAM.

I haven't.

It is set to AMD Ryzen Balanced. Is that the ideal option?

It just depends on the quality of your UMC and IO die. As low as you can go without causing problems. for 2033 Fabric and 3000 UCLK I can do sub-1.0V, but it seems that it causes some weird behaviour on iGPU (which I need for my second monitor).

auto setting probably is on the safe side. Mine sets auto 1.3V for 6400

 

[67Elco]

The temperature spikes mean little...just loading points. Your core temps look just fine...just disregard that CPU die reading.

Here is mine from just 5 minutes in Starfield...

Hmm I guess those X3D run hotter internally. I easily can pull 200 on the 7950X and be under 90c

Ryzen balanced? Not just simply balanced? Anyway, that's the one you want.

Hmm I guess those X3D run hotter internally. I easily can pull 200 on the 7950X and be under 90c

Yep. It's got a thermally insulating cache die sitting between the cores and the IHS.

Also, your 200 W probably means 90-90 W for the two CCDs, and 20 for the IO die. On the 7800, there's only one CCD.

Now that we mentioned it, I might pop my 7700X back in for some temperature testing with the Dark Rock 4. My curiosity is piqued.

 

[tabascosauz]

vcache always negatively affects temps, but doesn't seem to be that far off either.

On single CCD, actual CCD draw is somewhere around package power minus 20-25W. On dual CCD I've seen that number go closer to 40W.

I know that vcache negatively affects temps but it is weird because I get mixed signals about cooling this thing. Some say that it is easy to cool while others struggle.

Piece of cake compared to my 7900...I'm loving it so far.

It depends on how you look at it. You can slap any relatively big tower on it and call it a day. It's only that you'll get higher temps per watt consumed than you would with a non-X3D chip, but as long as you're within the limit, it's fine.

Edit: I have to add, I did struggle with a 280 mm AIO (be quiet! Silent Loop 2), so I guess, cold plate design is more important than cooler size with an X3D.

 

[freeagent]

A136w package power, 133w ppt my X3D is under 80c with a 22.5c idle, 19c ambient

Paste just went on a couple of hours ago

My 5900X can do 260w package power, 255w ppt at 85c with an 18c ambient

None of them are "hard to cool", just a little on the warm side by the standards of conventional wisdom. 7800X3D is basically not physically capable of drawing meaningful amounts of power, and besides 89C limit is pretty conservative as far as Zen 4 goes. And if you embrace the new 95C meta and use CO like you should, neither should the 7700/7700X be hard to cool.

A good and cheap dual tower like PA120 should work wonders. I'm planning to swap my FC140 for a white PA120 soon. Max all core is about 75-78C for me, and doesn't really change whether at 0/-30/-40 because of freq increases.

5800X3D had some pretty wild sample variation as to temperatures, so maybe that trend has continued. Some peoples' CPUs are just warmer than others.

The "vcache affects temps" is in an apples to apples comparison - e.g. 4.5GHz Raphael-X vs 4.5GHz Raphael, X3D should be a little hotter.

I'm actually debating what I should use to cool my setup, as I'm in the process of building out a new build. I'm looking at either staying with AM4 and going 5800x3d or moving up and getting a 7800x3d, so this thread was right on time.

Only issue is I don't know if I want to go PS120 or let my pride keep me attached to the Optimus waterblock that's less than a year old and continue my search for a Swiftech H240x3, which is turning to be an impossible feat..lol

My 5800X3D and 7800X3D max out at about the same temps, both a little bit under 80C. But the 5800X3D absolutely needed -28 CO to get there, while the 7800X3D is already there at -0, just at lower clocks. I've made it up to -40 pretty stable but certain cores start dropping when approaching -45.

7800X3D seems to run a bit warmer on the daily though in games, maybe due to the much higher boost in lightly threaded apps (5050MHz vs 4450-4550MHz).

You'll be fine with the PS120. I haven't found an opportunity to put my Foundation block back in either, because none of my CPUs post-5900X have deserved water. They just don't draw enough power.

 

[67Elco]

I went with water simply because I like the looks of my motherboard. Air coolers just cover it too much...I don't even like the video card in there.

Hi,
You'd like that gpu more if it had some copper tubes going in and out of it too hehe

What I will like is the day I don't need a video card at all. Already got rid of the rest of the cables.

auto setting probably is on the safe side. Mine sets auto 1.3V for 6400

Thanks. Will have to check and see what options I have.

I don't have any AMD Ryzen power plan, and neither should you, I think.

Did you upgrade from Ryzen 3000 series (or earlier) while keeping your Windows installation by any chance? If so, did you uninstall and reinstall the chipset driver?
