Just a quick note to point out an interesting fact of computer history. Amd recently announced it’s server beast CPU [Epyc 9965]
. Built in 3nm lithography, it supports 384 threads, a 12-channel memory controller and has a whopping 500W TDP. Windows 7 256 thread barrier is finally broken. As for an Intel, they are definitely can send their technology to the museum.

¶ INTRO WORDS Numbers, numbers, numbers … i say NUMBERS!!!!
It’s been a while since i ran into the craze of pointless benchmarks. And now I’m back with the absolute procrastination stuff. Are you happy with this?
Take a note that 3DMark 03, 3DMark 05, 3DMark 06, 3DMark Vantage [2007], 3DMark 2011 and 3DMark 2021 are not marked by ▒ sign, showing the fact that these programs lost the soul of demoscene and just providing comparison numbers, nothing else.
Messing around with the recently purchased Ryzen 7700 i ran into some rather annoying power related problems. The computer and monitor would go into sleep mode after about 5 minutes, despite the appropriate power settings in the Control Panel and third party software such as Process Lasso and Park Control being residential in memory.
I had to break my head to get out of this situation and traditionally i am sharing with you the solution I found.
Initially, I decided to install Windows Server 2008 R2, attracted by the opportunity to have a server-class operating system with increased I/O throughput in the works. But almost immediately i ran into compatibility problems [no surprise here] with my existing software. Some programs refuse to run because of artificial restrictions [you know licensing mambo-jambo stuff], some of which depend on components that are not present in Windows Server. It’s sort of possible to work, but you almost always run into little glitches here and there, even after converting it to a [workstation]
.
It was more than a two-year long run with [44 thread Broadwell]
, quite a nice heater. I have really enjoyed running multi-threaded workloads on it, but it is time to move on. As you may remember i’ve already tried [AMD in 2021]
, just to make sure that it is possible in a Windows 7 environment. And now i would like to jump on the red train again.
Currently we all know that [Ryzen 7950x]
and more importantly [Threadripper 7000]
series are working just fine in Windows 7 environment. Upcoming Ryzen 9950x confirmed to work already, because it is using the same socket [mechanically and electronically].
And now for even better news: [AM5 socket will be supported at least until 2027]
, which means that Ryzen 10950x will work without any hassles also.
So, it looks like the Threadripper 7995wx and Ryzen 10950x will be the last chips to work properly on the Windows 7 platform in the worst case scenario.
Himmelskibet [member of WinRaid community] has just discovered that modern 48-thread workstation CPU Threadripper 7960X can work in Windows 7 environment.
He was able to execute Windows Server 2008R2, with working USB3 ports. Testbed motherboard: Gigabyte TRX50 Aero D rev 1.1. “Good” BIOS version: FA BIOS [dated Nov 23, 2023] Nvme testing is in progress. I’m pretty sure that everything will work fine.
Here is a proof image:
[Original topic @ WinRaid]
If it works out with NVME and it will not give BSODs and substantial issues we could count that Windows 7 is capable of driving 192 threads then.
I’m quite satisfied with performance of my current workstation. [44-thread Broadwell]
paired with 64Gb of RAM, fast NVME and [24Gb EVGA 3090Ti]
shape solid desktop tool. However i’m planning distant upgrade to achieve maximum speed in Windows 7 environment. Just to mark checkbox that it is possible. In 2021 i already tried out modern platform based [around x570 in conjunction with Ryzen 5950X]
. System worked without any problems, thanks to modern [CanonKong Windows 7 drivers]
.
Information confirmed by [author]
of [hacked modern USB3 AMD drivers]
.
Please, take a note, that: ASRock boards is not compatible at all, due to removed proper CSM module in latest BIOS revisions. Asus mobos are acceptable, but have some issues here and there. Gigabyte is just ok. So, consider MSI to get yourself out of unneeded troubles.

As you may know X670 chipset is already supported by means of [CanonKong’s driver]
. [Ryzen 7950X]
is confirmed to work with Windows 7. Ryzen 8000 reported to use the same AM5 socket as Ryzen 7000.
CanonKong [confirmed above mentioned statement]
with his own commentary:
I think I will maintain driver pack for modern amd chips until out of my ability.
Ryzen 8000 still can work on Win7. So we can safely announce that Ryzen 8000-series will work without any problems.
Most of you already know how AMD substitute in terms of cores/threads count intel’s pathetic’n’degenerative CPU evolution into revolution. Drastic changes were brought by [Ryzen]
CPUs in consumer market in late 2017. [Threadripper]
and [Epyc]
lines were introduced later on [for workstation and server market respectively].
► [128 core / 256 thread Epyc Bergamo CPU]
It would be nice to see 256 threads in Windows 7 task manager, but i don’t think that it is possible due to lack of drivers.
Well known Chinese driver modder [Canonkong]
confirmed that [64-cores/128-threads Threadripper 3995WX]
based upon sWRX8 chipset works flawlessly in Windows 7 environment. Considering the news it looks like that more recent [5995WX]
will also work without any issues. So, we have plenty of headroom in terms of system performance. As for me, i have no need to switch to “recent operating systems” like Windows 10/11.
Here is brief [confirmation]
from the WinRaid forum:
As you already know i fed up using [modern Ryzen/Radeon hardware]
and decided to go a bit retro. Cheap Chinese clone mobos and second-hand high-performance cpu’s of previous generations induced me to rebuild my workstation and also fool around with Opteron-based server.
Here is [very detailed spreadsheet comparision]
of almost all available Chinese x79/x89/x99 boards on the market.
Like leaksters say Radeon 6950XT refresh will bring new 18Gbbs memory sub-system and [8-10% to performance]
. I’ve decided not to involve myself into GPU race and stick with plain 6900XT. It is a performance banger under Windows 7 environment. Imagery by spacedrone808 @Adobe Imagery by spacedrone808 @Freepik

Finally, I’ve managed to finish my retro DOS/Windows 98 build machine based on powerul Athlon. By finish i mean assemble parts on the table without any case. Why no case? Answer is simple: i’m lazy. And it is more convenient to me to keep it as open testbed for weirdo experiments of my own.
Collecting items took almost four months to accomplish this project. Puter consists of multitude parts, which were acquired around the globe.

Windows 200 is known for very fast performance, even compared to Windows XP and famous for absence of preinstalled bloatware. However, lack of drivers and software cripple system a bit. I was curious about ability to use this old operating system in 2022, maybe not as daily driver, but as a backup machine for secondary tasks.

Authoritative member of Win-Raid community [Canonkong]
confirmed that x570s chipset is fully operational under Windows 7. In terms of overall compatibility he recommends MSI boards. Please note that [Asrock motherboards are not compatible with Windows 7]
anymore because of notable BIOS changes. You’ll encounter A5/7E BSOD screens on random basis. The most distinctive feature of x570s chipset compared to x570 is absence of active cooling. Also it will support upcoming [Ryzen 5950XT]
CPU with larger 192Mb L3 v-cache.
Long time ago I’ve noticed prolonged trend to destroy advanced technology and sell cheap plastic things, powered by marketing slogans, which have zero significance in real life. Appointed trend applies to almost any products in our life, especially consumer and even professional electronics.
Some solid proof then.

brought super advanced Amiga computer in the middle 80s, which had some really advanced stuff like GPU Blitter and Fast-Ram technologies. Nowadays Amd is working on stuff similar to Fast-Ram, which they call Smart Cache.

Described issue related to Windows 7 and modern AMD-based GPU’s. Some users on Reddit [have reported]
,that there is a problem with modern Radeon cards. Core of the problem: sometimes monitor can’t wake up from sleep state and shows up no signal message, despite the fact that computer continues to operate. Keyboard input, sound output are working normally though.
Of course you can set Windows power management not to turn off monitor completely, but this will be quite a waste of energy.
