New Threadripper PRO 5975WX Beast

Hello! I am new to the Level1Techs Forums. I thought I would post the specs (and pics) of my newest build here and solicit any feedback or recommendations for tweaking the BIOS for this particular board.

I am a pretty experienced builder and have put together several Threadripper 3970X’s in the past - but this is my first experience with Threadripper Pro.


  • Fractal Design Meshify 2
  • Corsair HX1000 Power Supply
  • ASRock WRX80 Creator
  • Threadripper Pro 5975WX
  • Noctua NH-U14S TR4-SP3 Cooler
  • 256GB (4x64GB DDR4-3200 PC4-25600 2Rx4 RDIMM) ECC Registered Memory
  • 1 x 1TB Samsung 980 Pro NVMe SSD
  • 1 x 2TB Samsung 980 Pro NVMe SSD
  • NVIDIA RTX 3090 FE
  • Elgato Cam Link Pro

I use this workstation for digital forensics as well as video editing for my YouTube channel (13Cubed)… and of course, occasional gaming. :wink:

This is actually my first experience with an ASRock board - I normally use ASUS or MSI. That said, so far I’ve been impressed. I really like the dual Intel 10GbE NICs, Thunderbolt 4, and the form factor (much smaller than many other WRX80 boards).

Running BIOS v5.01 which is currently the newest (shipped with this version). I have not made any tweaks to the settings and I’m not interested in overclocking. That said, are there any defaults that any of you would recommend changing to squeeze out any additional performance?


Thats some sexy cable management! I love it!

How is your airflow configured? Cpu fans are blowing upward? Front fans pulling in air and rear fan pushing air out?


I didn’t read this part until after writing all this, but in my opinion, PBO and curve optimizer isn’t overclocking

with that cooler it will limit how much wattage you can pump into the CPU but that doesn’t mean you can’t tune it

what I would do is go into AMD overclocking, I think its in AMD CBS or PBS

  • Set PBO to advanced
  • set Power limits to either auto or disabled
  • Set the Curve Optimizer to a NEGATIVE offset with the value of 30 (max)

from there you can try and raise the max turbo by 25Mhz increments but even if you don’t extend the boost limits, setting the undervolt will let you boost higher all core

you may need to increase your power Budget but you definitely won’t be able to hit +200mhz and the power limits unlocked with that cooler

my experience with that chip and that board was with a custom loop, unlocked the power limits to motherboard, set negative offset to 30, and +200mhz and it was pumping like 420w through the CPU

but maybe your chip is different and maybe you won’t be able to hit negative 30 stable so experiment


Yep, exactly. That’s one of the reasons I wanted to use the Meshify 2 instead of the Torrent or Torrent Compact - so I could exhaust air out the top.

Thank you! I appreciate suggestions and detailed info.

Interested to hear about your experience with the Noctua tower. Given it’s cooling limitations, would you recommend this option over a custom loop? How much wattage have you managed to push through the CPU?

For custom loop
500w with PBO and without curve optimizer
410w with PBO, +200Mhz, motherboard limit, and -30 curve

I think it was like 280w is the max that noctua cooler can handle, I would definitely get a second fan for push pull as it will saturate it
You can leave it at +0Mhz and either auto or disabled on power limits so you won’t exceed that wattage and apply a negative curve to get more out of the same wattage/raise power effecincy

My sample size is 1, maybe not everyone can hit -30

I’m not a fan of water cooling… just don’t like the hassle. The Noctua cooler keeps idle temps in the 50s, and the absolute max I saw after multiple Cinebench R23 runs was 81. It’s a non-issue. I’m pulling air from the bottom of the tower and exhausting out the top, as you can see from the pics.

All that said, when I had a 3970X I used an IceGiant, and it was absolutely amazing. If they had a bracket adapter for sWRX8, I would definitely grab one.

AIO. Water cooling without the hassle. I’ll be putting the finishing touches on my 5975wx this weekend using a MasterLiquid ML360 AIO. I’ll supply my idle temps when up and running as a comparison. I won’t be OC’ing either.


Yeah AIO would definitely be an option – will be very interested to hear about your results.

What specs for your new 5975wx? Just curious with regards to case, power supply, RAM, etc.

I just noticed that the infamous Enermax Liqtech TR4, yes, the one that tends to grow algae after a while, is offered with a 5 year warranty for units purchased after 5/2021 (vs 3 year before). I wonder if this means that Enermax has fixed the previous issue…

I think you make serious problem…
Threadripper Pro series all is using eight channel memory, NOT quad channel memory…
You need at least 8 pcs RAM, I highly recommended to use 8x32GB like my setup or 8x64GB if you need more capacity…

If I can know what’s software you’re using for digital forensics ?

The platform will support 2, 4, and 8 channel configurations. I may throw another 4x64GB in later.


Why not 8x64gb once ?, yes they can run even with single slots only, but you can’t get maximum memory bandwith

Wasn’t in the budget - that’s another $1,200.


Why if use 8x32gb first, then if you have enough budget, sell it and buy 8x64gb ?

I use this way… but its up to you… another advantage is, if you found 8x32gb is enough, you don’t have to upgrade to 8x64gb later…
