So we should treat its results as "idle score" from this version on?

No.
( I expect a patch for AIDA64 for the unpredictable choice of multiplier )

Results from " back to back " runs should be consistent.
( if it is a benchmark )

Newest chipset drivers. Other than that, I think it should be good to go. Which store did you find one in stock?

Think I should upgrade windows to 20H2 from 1909 first?

Unfortunately it was not really a store. It was a best offer on ebay, but at least the seller is close, like one city over. I should get it soon.

Tuff decision. I think I would update to 2004 now.
( there are updates to apply to 2004 waiting )
Otherwise, I believe you will have a monster sized update to deal with.
( hours ...... )

It shouldn't be that bad, but who knows. I tried it first on my X99 rig, and that went smooth enough. I am pretty sure less than an hour from 1909 to 20H2.

I would upgrade beforehand just to make sure everything is up to date but I'm mostly a Linux user now so I might not be the best person for advice on that.

Strange that your AIDA Memory benchmark has 68.3ns with 3667CL16, but I get 61.5ns with 3600CL16. G.Skill TridentZ Neo 4x8GB kit.
Also the cache BW is totally different. You have older build which is probably not updated for Vermeer.

I forgot to test it with my CL14 3200 MT/s kit. Not gonna change the RAM again,

I've updated AIDA for my 2nd post and there I'm under 60ns with slightly higher clocked RAM.
Also L3 cache is more in-line with your results there.

People running the May 2020 Update will have a faster overall update experience because the update will install like a monthly update, just as it was for devices moving to Windows 10, version 1909 from version 1903.

Issues

I'm still waiting for it to " appear " as a monthly.
Some have already had this upgrade.
( with issues ) , and they pulled it out of public access.

 

[Shmee]

Well the update went pretty smoothly here, all done. I will do chipset drivers next.

 

[GoodRevrnd]

Well I finally managed to get a 5800X ordered. Should be here pretty soon. Besides update motherboard to latest UEFI, anything else I should do, like driver or windows related?

Eh? Where did you find one? Is there a time of day it's best to check for stock updates?

He got it off Ebay.

 

[Justinus]

I just managed to snag a 5600x on Amazon.... by spamming the "Buy Now" button from the in-stock version of the page that was locally cached on my phone after the product was shown as out of stock.

I used this knowledge to create a local override of the 5950x page that exposes the Buy Now button, and when amazon starts making changes to the 5950x page, indicating they are beginning to stock them, I'm going to spam the "Buy Now" button until it takes.

If it works.
In order to beat the bots, you must think like the bots.

Disclaimer: I fully intend to either cancel my 5600x order if I snag a 5950x or use it as a holdover CPU and sell it for a reasonable price. No scalping or greed here, I just need to get this box up and running asap.

How is everyone doing for temps on your 5800X? Mine seem quite excessive, I’m hitting 90C and throttling at 125W in ycruncher BBP, even with flow at 400l/hr and the fans in running full out. Coolant temp never rises above 25C, so it really seems like an issue removing heat from the chip. I’ve repasted and not much changed.

I know Zen3 runs hotter, but I am concerned the cores are getting to 90 and throttling even at fairly reasonable power levels.

 

[PrinceXizor]

I don't know if its the same as HVAC, but I don't understand why it would be different. You can flow your transfer medium too fast to effectively cool. In other words, you need to have the flow going slow enough to have the time needed to transfer the thermal load. Fast flow is not synonymous with max cooling. With your coolant temps being so low, you should try reducing the flow. But, I don't know AIO particulars. Is coolant temp measured in the reservoir? Just before the processor heat sink? For a fixed volume system like an AIO, there would be an optimal flow rate that maximizes thermal load transfer at the processor while transfering said load at the radiator. It would be based on the thermal characteristics of the processor heat sink, the heat pipes, etc.

Can you check your voltages and frequencies at full load? You're not the only one to report unexpectedly high temps on a 5800x but others report temps are fine. If your voltages and frequencies are as expected at full load, then that leads me to further believe there is a bad batch of 5800x CPUs that had an issue in packaging/assembly and the die to solder to IHS connection is bad or maybe the IHS is extremely convex or something like that. You should not be hitting those temps with your cooling setup.

 

[MrTeal]

I ran two test series with ycruncher BBP running. I used Ryzen Master for settings, and monitored frequency and voltage in HWinfo. The first series I left the peak core voltage setting fixed at 1.35 and altered all core frequency, the second I fixed frequency at 4GHz and varied the voltage setting.



Temperatures seem to scale linearly with power, the numbers just seem very high. Idle temps with 5 cores sleeping and the other 3 running <500MHz seems to be around 26-27°C, FWIW.

In any practical liquid cooling setup, higher flow rates decrease the temperature difference between the CPU and the water. You definitely get to a point where extra flow doesn't have much benefit, but I don't think you can really have too much flow.

 

[MrTeal]

The type of load does seem to affect it quite a bit as well. Cinebench R20 @ 4.75GHz/1.4V give 114W CPU power and 75°C, which is 9°C lower than at the same power in ycruncher.
This weekend I might mess around with it lower temps and see how it does with a water temperature closer to 0.

I'm somewhat surprised so many people are surprised that 5800X is hot. It's a 105W TDP part (the max possible on stock on AM4), with a single chiplet. So unlike 5900X and 5950X the TDP is not split between two chiplets, unlike 5600X one chiplet is not limited to 65W TDP. With that added headroom 5800X is bound to be running at the border of the thermal envelope. If people expect/want it to run like the other three chips I'd suggest lowering PPT or use eco mode.

I want to add that the heat is inherent problem of the 7nm process, For example Zen3 in eco mode (65W TDP) will still boost to 5+ GHz and cause temperature spikes. Eco mode is targeting PPT, whereas per core temp could still spike due to a single core boosting to oblivion.
On the bright side, you dont lose ST performance in eco mode, and if the fan noise is bothering you, you can alter the fan speed profile because according to AMD Zen3 should be perfectly fine working around 90 degrees celsius daily.
5800X is particularly very boosty in ST, but since it is not as highly binned as 5950X it uses more voltage to reach the higher speeds and therefore cause higher temperature spikes.
During all core loads, surprise, the temperature actually does not spike. This is my observation so far.
But Zen3 has a much better temperature curve than Zen2 for sure.

Do we see the same thing when you compare the 3600X to the 3800X?

or is the heat output the same for 3800X vs 5800X since both are 105W TDP parts?

Were the same high temperatures seen on the 3800X? It is also a single chiplet, 8 core CPU on 7 nm with a 105W TDP.

I'd think at the same clock 5800X should be comparable to 3800X, they are on the same node after all. The cause of the difference should be 5800X clocks significantly higher and also does a better job keeping those high clocks.

The 5800x hits higher frequencies at lower volts though. They both have very similar power consumption with all core loads (5800x uses less than 10% more power).

Well yes, that's the prerequisite for it to be able to reach higher frequencies than 3800X.
