I'm in the US, but I would buy a 96 core at 50% off.  Where did you find that? I saw people on eBay selling 7980X for like 3,500... But I'm a little sus about that. Sorry I haven't posted in a while, just had a new baby, and it's my first so it's a learning experience. But I got some really good updates on the 7980X. Pulling over a 39k on Corona bench and staying under 80c. I'll post results when I get home.

Oh duuude, congratulations!! That's quite the news! May the learning experience be a linear curve :)

US you say? Well Newegg has one listed for below 5k. Here is the link:

I'm looking at a chart that Supermicro provides and they've been discounted like this since basically the first week of this year. I have no idea why and even though these are clearly still expensive products they are also almost comically cheap at the same time lol.

I am beyond tempted myself. A single 96 core can replace and possibly even outperform two Zen 3 64 core Epycs at a much lower power consumption. Sheesh.
Thank you! It's been great but need sleep! So yesterday I though you was talking about the 7995WX 96 core, was reading it on my phone and like I said I need sleep, lol. The EPYC 9654 96 core seem not to be very good at all, they only pull a 31k on Corona Benchmark and that's with 2x AMD EPYC 9654 96 core CPU's.  my 7980x at stock pulls a 34k.  But from what I've seen I do think there is some issues with Corona and 2x CPU's.

I got the best Overclock so far by keeping everything stock and only changing the CPU core ratio to AI Overclock and setting a temp limit of 80C.  This gave me a 39k in Corona Bench, of course I can use a higher max temp limit and get a better score also. But I think for constant rendering staying under 80c is really good, not sure how much more wear and tear on the CPU there might be if I run a max limit at 90C.  With the next system I'm going to try a better cooling system and see where it gets me.

Before I kept getting a beeping or constant beep if I overclocked to much. I could not figure out what the issue was. I was thinking VRM overheating but on this motherboard they are suppose to be really good with good cooling. This had me scratching my head for a few day. Then I realized what it was...... It wasn't even the computer, lol... it was the APC Battery Backup system behind it. The overclock was pulling so much wattage that the APC UPS was alerting me with a beeping or constant beep. Face Palm!

@dfcorona got any updates maybe? Totally curious to hear how the 7980x has been treating you.

By the way, I have just noticed that roughly since the start of the year the top of the line 96 core Zen 4 Genoa is being heavily discounted (and other CPUs too). A new 9654 is commonly available at below 6000€ and I even found stores that sell them for 2500€. They used to cost like 10.000€.

I mean it is still a lot of money but we are talking about 96 cores that seemingly go above 3ghz with all cores. These are now basically 50% off.

I actually had a much better overclocking and temps now keeping everything at default and then just enabling AI Overclocking.  I have some shots of benchmarks and temps I'll post. But right now the monitor hooked up to that system broke so I have to wait.

Okay I'm reviving this thread again because one of my monitors just fell and broke, what a great day....ugh. I was looking at the two monitors below, which one do you think is good? I always had Dells 21:9 for quite some time.

Dell UltraSharp 34 Curved USB-C Hub Monitor - U3423WE
ASUS ProArt Display PA348CGV

There is this dell also with a 120 HZ

Here are some overclocks.  One at 6400MHZ RAM and also set temp max to 80c and pulling a 39k, but I would get a loud continuous beep from the motherboard. I then set from Expo I (DOCP I) to Manual and set just the RAM back to 4800MHZ and also set temp max to 70c and I get no continuous beep anymore and pull a 38k.  You can really hear the VRM fans ramping up. Not sure what the Beep is telling me, I'm not all that great at overclocking to be honest... never really overclocked before with my previous systems because there wasn't much to gain, but with the new 7000 series there are some really good gains. Not sure where I feel safe with the Temps yet, I know you just don't want to go over 95C. But for continuous rendering I don't want to be close to that either.

It's the same ultimately, like setting a pass or time limit for rendering :- ) Temp limit sounds nice on paper, but could be quite fluctuating. Watt limit should still adhere to temp limit since that's hardcoded into the firmware (otherwise our PCs would burn).

10perc. rendering improvement for 2X the power draw and massive temp spike might not be worth it though. Looks like the 350W was quite smartly chosen. Thank you for testing it out though :- ).

Nice build, looks like worthy investment.
Thanks, I'll give it another try soon. See where it gets me and I'll post some benchmarks and temps. Even 10 percent is kind of worth it if temps are good for long animation renderings. I will be building another 7980x system soon also, decided 2 of them is a better investment compared to one 7995wx.

700Watts at 95C degree is not bad at all with just AIO cooler :- ). So what performance did you gain?
You can try 600Watts manual limit.
I tried it real quick for like half the benchmark, but didn't let the full benchmark finish since the motherboard was beeping like hell at me.  Corona was reporting around a 37k. There is a temp limit I can set in overclocking, not sure if I should go that route or try by wattage like you say.

I did a OC on the 7980x today. Used Expo I which is equal to DOCP I it seems. Don't know if I like the temps though...

Here you go

@dfcorona may I ask what the all core turbo is when running say the Corona 10 benchmark for example?
The system is busy rendering right now, but once it's done I'll run it and post the results.

Oh I never cared for specific number. Laptops run for 105C for last decade and they do ("mostly") fine. At worst, you will shorten their lifespan from two decades to single decade..

With desktops, it's mostly about using the temps to gauge potential for additional performance (or silence).

But temps in fifties.. that's a bit miraculous :- ) 3990X/5990WX can run in 60s for simple multi-threaded tasks (like Corona rendering when not doing denoising or other demanding tasks). But mid-50s?
Maybe really good silicon lottery, or good room ambient (my room very quickly gets into 25C... even with all heating turned off and windows open in middle of December).

So the 7980X perhaps is really good chip in this regard and may easily eat lot more than stock 350.

But then the general temps I see on Reddit are quite bit worse in general compared to 3xxx and 5xxx series, which would make sense for Zen4 chips.

Threadripper and AMD in general always had issues with reporting accurate measurements with all the Tctl/Tdie and Offsets being taken into account differently by different applications. Ryzen Master vs HWiNfo vs HWMonitor, etc.
My experience is that most people do not setup good airflow and don't choose better cooling options.  I was always big on cooling, and my systems always ran cooler than most I have seen.

Checked the 7970X temps, yeah that's not doing well. So putting that idea on ice.

Threadripper with 8-dies like the 64/96C is more reasonable choice. Your reported temps still seems fairly weird, I haven't see anyone report anything that low. How are you reading/measuring these?

I know the CPU overclock is really where I'm going to see the performance boost, and probably looking at 20% increase in Corona.

Yes I feel 7980x is much more snappy! I haven't tried with Corona yet, only the Benchmark. Yeah transferring with Star Link will take some time. 7000 series would probably be better for mobile than 3990x since it can be cooled better.

Just pulled the G.Skill 128GB kit out and replaced with 192GB kit.  BIOS is set only at defaults, ram is only running at 4800.  Even with that the system is fast, 34k with Corona.  Once I set ram to 6400 and OC I can't wait to see the performance boost.  I'm expecting 2x 3990x. But the 7980x machine is finishing out a job right now.

I would go just go with 7980x if you can, plus I think it cools better.

Once I get time to Benchmark the 3990x vs the 7980x I'll post some results.

Not yet, hate that you loose warranty and they can tell but I'll probably still do it. I think I can get another 20% performance without going to crazy. Right now I'm getting 34k on Corona benchmark and temps are mid 50's.

Dang, only mid 50s full load? That's beyond impressive :)

Yeah that OC fuse is a rather interesting addition to things. According to a statement from AMD they will respect the warranty IF it did not die from OCing (regardless of the fuse) - but how they'll figure that out I do not know :)
yeah rendering on Corona benchmark I was pulling 34k at 54.4 temp.
