Is the 3990x the multiboxer's dream cpu?

[WOWBOX40]

I should mention that, yes, in short, if you plan to stick playing 24 accounts + be able to use the ftl system + you want to play on 1 pc = this cpu meet those requirements.

You are going to have to pay a premium though... the cost is no joke.

There is a clock speed curve that hits the sweet spot for all-core overclocks at the 3900X/3950X @4.2GHz and tails off the more cores you add. If you want absolute per-client performance, jamming that much thermal load into a single PC might not be the greatest option. That said, as noted above, having all of them on one PC means you can take advantage of things like VideoFX that do not work on multi-PC setups.

I would hesitate to bother with non-EK water blocks on it based on my reading a few months ago, and based on my experience with a 3900X I doubt a 360mm radiator is gonna be enough if you actually load the CPU down to 90%+. That said, I highly doubt you will be CPU-bound as it's more likely the GPU will become the bottleneck pretty quickly.

I highly recommend doing some research on coolers including VRM water block support for the motherboard(s) as a 280W TDP CPU is going to stress the power components pretty hard. Hell, the chipset on my measly X570 has its own heat pipe + fan setup (and yeah, it can get pretty hot if you don't factor that in). Thermals are going to be the hardest thing to elegantly control on that system, IMO.

Which x570 do you use?

Yeah the thermals got me scared to buy this chip honestly.

I'm running the MSI MEG x570 ACE.

Honestly, the thermals wouldn't be such a concern if cooler manufacturers, BIOS designers, and etc. would all get together and do a less sucktacular job at designing pump/fan software. The NZXT software that came with my X72 was SO. DAMN. BAD. I ended up just leaving the BIOS fan curves at defaults and picking up a copy of Argus Monitor and setting all the dynamic curves in that app. The chipset temps were running around 67C+ all the time and the fan rarely came on. With it running at basically minimal speed via Argus Monitor, the temps rarely ever get over 60C now even under my heaviest loads. I poked around on mine with a thermal camera during stress testing and the VRM areas never got very hot. Granted, I'm only on a 3900X @ 4.2GHz. The default settings were MUCH worse as the voltage would ramp up to like 1.465v and then it wouldn't take too long before it appeared to start throttling (with Prime95 spiking things up to 97C). Setting it to a flat 4.2GHz and undervolting to 1.25v cured all its ills; Prime95 temps dropped to ~74C after the cooler heat soaks and it rarely gets above ~55C in any gaming I've done yet. It's been more stable under load than any system I've had before.

Win10 Home maxes at 128GB of RAM while Pro goes up to 512GB, Home is also limited to 1CPU socket, but Pro and Enterprise will do 2 CPUs. Win10 Pro and Enterprise essentially cap at 64 threads. MS will say they support up to 256 threads on Pro/Enterprise/Server, but not optimally - Its so bad that performance is often better with 64 than it is with 128 or 256 threads. You can actually disable cores on high end servers and watch performance go up. Such that at work we're sticking with twin Xeon 8280's (HT disabled) as opposed to swapping in Epyc 7742 if its on a Windows server (don't have this problem if you're on RHEL or ESXi.)

Anyone here tried a 3990x with different workloads in any version of Windows?

I knew MS announced support for 64+ threads since the release of the 3990x but I wasn't aware that it still isn't optimal. So performance is still better on a 3970x then?

The maximum memory on TRX40 motherboards is 256GB (32GB x 8).

And cpu speed will be like 3,6 to 3,8ish. Not 4.ish or more like on other "gaming cpu's". Its not the end of the world. Having 2 cores and 2 threads per slave game on 3.8 works fine enough.

It also mentions that some motherboards cant overclock and the vrm temps. Active cooling with fans at the vrms = good thing. Or ofc use motherboard watercooling.
