Is the 3990x the multiboxer's dream cpu?

[WOWBOX40]

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.

@wowbox40, whats your setup with your 3960x? How is the cooling on that since it's also a 280w but with less cores?

make it go faster

1. Fractal Design Celsius S36 CPU cooler.

2. ASUS PRIME TRX40-PRO, Socket-sTRX4.

3. Corsair Vengeance LPX DDR4 3200MHz 32GB.

2x16GB DDR4 3200MHz (PC4-25600) CL16, XMP 2.0. Productnr.: CMK32GX4M2B3200C16. 2 sets = 64 gb.

4. Radeon vii gpu, 16gb vram.

5. Corsair HX850i, 850W PSU. 80 PLUS Platinum

6. Intel 660p 1TB M.2 SSD nvme. Around 2 gb/s

7. 2 x 24 inch monitors. Main game on bottom, 9 slaves on above monitor. I use a 2 monitor vertical stand for each of my computers.

I use it to run 10 accounts. 1.3 volt. All cores at 4.0ghz. Cpu temps are around 66 celcius. Nothing out of the ordinary on other parts, like vrm etc. I run hwmonitor 64bit while i play.

Thanks for the response. The temps are better than I thought, especially since you OC'd it. So that S36 cooler doesn't cover the whole cpu and you still get those temps? Or does it come with a larger plate that covers the whole surface of the 3960x?

It was the best cooler i could find at the time i built the pc. Its not ideal, as the coldplate doesnt cover the entire cpu surface. It does touch within the 4 parts this cpu has though. But temps arent bad at all. But obviously try get a cooler thats properly suited for the threadripper, if you are planing to aio cool it.

The higher cores variants probably look different under the skin = you will then need a full cover cpu surface block.

I can take it for a torture raidtest later this saturday. I will then provide a better update, tempwise.

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.

So after some raidtesting:


Cpu max temps 72 degree celsius.
System RAM used: 65% (of 64 gb)
All cpu cores at 1,3 volt.
All cpu cores at 4.0 ghz.
Cpu max utilization: 79% (the individual cores varied from 73% to 92%, most were around the low 80s)
Gpu max utilization: 100%
Gpu memory vram utilization: 45% (of 16 gb)
Gpu temp, max: 74 degree celsius.
Total system watts: around 600 watt power draw.
Ssd M.2 temp, max: 39 degree celsius.
Corsair powersupply; max 41 and 54 degree celsius. I use "single rail mode": (option you can turn on in the corsair link software).


All games are set to 60 fps front, 30 fps background. 1080p.
Slaves games all set to grafics settings 1 (some slightly increased) and settings around 3 on the main (some slightly changed).


No other temps were out of the ordinary.

pc case:
Fractal design define 6. All fans used, intake fans speed set to 100%. Outtake fan speeds set to 50%. Positive pressure.
And yes, the AiO fans are going at 100% when the going gets tough. Aio pump always at 100%.

Headset: /always on

Just so you are aware.. there is a glitch in the "Ryzen master" utility.

I thought my main character felt like having around 20+ fps less that it should, and yes, low and behold, the utility had turned OFF half the cores, so my 24 core / 48 thread cpu ran with 12 cores / 24 threads instead.

I solved this by pressing "reset" in the lower left corner of the utility, then it restarted the pc.
Then overclocked it like normally, using the tool, but DID NOT enable "use compability for older programs" = it then worked.

Sidenote:
Its good practice to have open (just to doublecheck) the following programs, to make sure all cores etc actually are enabled / correct:
1. windows task manager.
2. CPUID HWmonitor 64 bit.
3. CPU-Z 64 bit.

The temps are around the same, 70 degrees (max when raiding (AKA hard raidtrash mobs packs, = intense action), but cpu utilization went down by a LOT, obviously by effectivly doubling my amount of cores/threads.

Happy days.
