AMD Ryzen 7 5800X 3D Cache Eight Core 4.5GHz (Socket AM4) Processor - Retail - Go Go Go xD

Just tried my -30 all core when gaming. No issues as such and temps still high 60's but it didn't have a random spike when launching a few things so I guess its fine.

Edit:

@Richdog , Just tried the multicore test you asked the other member to run.
Max temp 79.5deg, All core 4398Mhz Score 14457 thats with a -30 neg offset in the BIOS. I can rerun tomorrow without an offset.
Thanks michty_me, that is almost identical to my temps and scores, so at least we know it is working consistently! :)
CBr23 - 83 degrees All core 4.55ghz, Score 14823, 1.236v, MSI Kombo strike level 3
Is that 4.55ghz a sustained all-core clock? That is around 150hz higher than I can get, which in the end is a tiny and insignificant amount, but interesting to note. Maybe you have good silicone.

PS: I recommending adding your specs to your sig like me, makes it easier to see what ayou are running. :)

I'll have to give prime a shot. Was -30 stable in gaming or did you not try it with issues on prime. I recall your previous post where you said you may try -27 but didn't see the point.

-30 was stable in gaming but I thought I'd give prime a go just to see how hot it could now go at -30 but also if it would be stable. Think it errored within 10-15 minutes.

Now, everyone's definition of satisfaction with an overclock/undervolt being stable will vary. Many here will say if you're stable in gaming and that's the most stressful action the CPU will see, then its fine.

The way I see it, the CPU's task is to perform arithmetic. If it calculates 1+1=3 for example, then to me its not stable. That is a naff example and the calculations that Prime is forcing the CPU to do are way more complicated and not typical of your usage.

I'm a pretty risk adverse person, so like it to show stability in something like Prime.

You're correct in that I did go to -27 and it was Prime stable overnight for me but I settled on -25 in the end just for added peace of mind. Still provides a substantial decrease in temperatures, so more than happy.

Yes sustained 4.55ghz all core. Not done any tinkering just latest agesa bios, AMD drivers and enabled MSI kombostrike level 3 on the bios. Specs MSI b450 pro carbon and 32gb ddr4 3200mhz ram
 
Probably not the ideal place to ask this but now you've mentioned BIOS. :) I've tried looking for a changelog for AGESA in the past, in typical fashion manufactures notes on what's been updated from one BIOS to another is woeful, but i always drew a blank on even finding out what the latest version of AGESA is let alone what's changed from one version to another. So does anyone have a link to some place that lists AGESA versions and maybe a changelog.

Doing some troubleshooting for why my X3D always goes up to 91C regardless of what setting I use in PBO tuner. Could my poor application and on closer inspection, a very old tube of Arctic Silver 5 explain the issue?

Using a Alpenfohn Dolomit Premium.

I think my tightening of the HSF might be at fault. Just put in my 3700X to confirm it's working, and then I removed it - the thermal compound was spread in a much more uniform manner. Only difference being, is me tightening the HSF more.

Pressure could well be at fault
 
I have the Alpenfohn Brocken 2 and suspect the mounting process is exactly the same looking at your picture.

I do a half or so turn on each screw alternatively until the screw locks outs. I also applied paste using method of blob in the centre followed by 4 dots in a square around it.
 
The only thing with the 3D 5800X is that if you want to do emulation then clock speed matters, the cache has no effect, so core speed sensitive tasks will take a hit, though to be fair I am pretty sure a 3D cache 5800 is fast enough for most anyway with emulation or a similar work load.

For example my 5800X standard can run all core 4700mhz at 1.26v and never exceed 75c.

PBO I can easily let hit rip at 4.95ghz in lightly threaded things, but the base clock will drop to like 4.65ghz under load and reach around 86c.
 
Nowadays for both AMD and Intel there is so little left in the tank, the extra power and temps arent worth it., Same with gfx cards now.

There is only memory where, if you have picked the right memory with the right ICs, then good gains can be made by overclocking for free.

Its all a bit boring nowadays. I started off with an Athlon xp cpu which i modded with a graphite pencil to run at 40% higher speed which is when I joined these forums. There was up to 50% to be gained for free each generation.

Nowadays you can play around for ages just to gain less than 5% in benchmarks that you cant even notice in real life.
E5640 Xeon and 2500k / 2700k user here, miss those days, clocked my E8600 XP rig pretty well to 3.9ghz with a Radeon 5870, still going strong.

@Richdog I ran 3 back to back multicore cinebench runs. My room was 18c First run was 65c second and third runs were 66.5 reported from hardware info.
All core boost 4450
This is the version of the cooler I have installed https://www.overclockers.co.uk/noctua-nh-d15s-chromax-black-cpu-cooler-140mm-hs-03r-nc.html Even though its the compatability version for tall RAM its still a chunky boi.
I have the same cooler but i guess there are some other factors keeping your temps 10c lower. Your ambient is a few degrees cooler and my GPU and case size and cooling could also be a factor.

How high do you run your CPU and case fans when doing this benching, are they at 100%? Also which case (useful to add to your sig)?

Hold on just a minute, a while back you weee telling folk the 5800X3D was no faster
Than the 3600. What happened?
 
Thought I had a breakthrough there, looked like it was going to settle around 80C. Eventually jumped up to ~90C after a short Prime95 load.

The small FFT test will do that at stock voltage for me. At stock, Cinebench would also hit 83oC and gaming less than that.

What are temps hitting during a Cinebench run for you? If it's less than 90oC then I wouldn't worry.
 
Yeah I think I got my expectations all wrong, P95 is the worst case scenario. Been playing Arkham Knight (not the most taxing) and the temps are absolutely fine. Still chuffed with it especially in my 5 year old CH6.
