CPU/Mobo [DISCUSSION] AMD 4700S Desktop Kit

Haha, no, not a router — this is a VM host. I can squeeze in twenty 1GB Windows 10 VM's in that 16GB of memory by over provisioning. The multiple network cards are for three different networks — one for corosync, which is needed by proxmox to keep the cluster in sync, one for traffic to the internet and the last one is used as a migration/backup network.

1GB Windows 10 VM's

Huh, just wondering... What do you do with such a small amount of RAM allocated to those VMs?

 

[rsaeon]

Theoretically, you could tie each vm to a proxy and downvote your enemies on reddit.

Also theoretically, you could sell likes on social media to desperate/vain people.

"Hi, could you share your experience with Proxmox virtualization? I have two of those boards and I'm planning to install a 512GB SSD and a 4TB HDD on each, setting them up in passive mode for backups. I'm concerned about whether the cooler would constantly run at 100%. My plan is to use them for a NAS, firewall, Plex server, BSD, Windows 2022, and Debian."

"¡Hola! ¿Puedes contarme cómo te fue con la virtualización de Proxmox? Tengo dos de esas placas y planeo ponerles un SSD de 512GB y un HDD de 4TB a cada una, configurándolas en modo pasivo para hacer backups. Me preocupa si el ventilador estaría funcionando siempre al 100%. Mi idea es utilizarlos como NAS, firewall, servidor Plex, BSD, Windows 2022 y Debian."

I'm not using the stock cooler, I've swapped it out for a Deepcool tower cooler with @SunnyBoi's adapter from earlier on the thread:

With the newer BIOS there is no need to change the cooler. Idle is 63 degrees and daily usage like browing and watching movies it does not go over 65. Power plan MAX CPU 70 In games, load temps dont really go above 75 with full 4.0Ghz boost now. Power Plan MAX 100. Has I said in my early post...

As a VM host, this is a really good system, it hardly ever needs rebooting (all of my first and second gen Ryzen systems need weekly reboots). The only draw back is power consumption — A Ryzen 4500 paired with an A320 board is far more efficient and upgradeable/versatile. If this wasn't such an iconic piece of computing history, I wouldn't be using it.

Speaking of which, I noticed PrimeABGB has a few boards in stock at 13k each @Alucard1729:

Потребляемая мощность — это то, что я хотел бы изучить подробнее позже: цифра 75 Вт была указана при включенном AMD Cool n Quiet в BIOS.

Hello, I want to change the heatsink on the processor, it’s not quite visible in the photo. Is the processor chip slightly higher than the processor body or are they the same height and form one plane?

The 120mm fan is in

Temps dropped by 10* wow. Not to mention the noctua fan is super silent even at top speed. Average clocks have also gone up by another 70MHz

Hello, can you add a more detailed photo of the cooler mount, I bought a PC with this kit, now I need to solve something with cooling. Is the processor chip higher than its frame or are they the same height and form one plane?
Which type of radiator is better to choose? Top flow blows on the motherboard, but the hot air is worse on the hand. The tower does not blow air on the motherboard, could there be problems with the VRM

 

[rsaeon]

Here's the laser cut adapter mounted on the motherboard:



The processor sits lower than the frame, I'm reusing the original spring loaded screws here.

There's plenty of clearance around the processor area with this adapter @Alucard1729:



I'm using the DeepCool AS500 here, I've mounted its mounting clips directly to the frame and the mounting pressure seem adequate:



It has its own spring loaded screws, which is what DeepCool appears to have standardised on all of their air coolers now.

Close ups of the how I attached the original spring loaded screws with the C clips that came with them:



The Deepcool brackets are mounted with simple M3 screws and whatever nuts I had at the time:



I think those are the knurled nuts that came with the AS500 but any button head M3 screw+nut would work.

Tower works alright for me. if you have another fan in the system (intake or exhaust), that should be enough for VRM cooling. The VRMs are rated for 150C TJMax, the VRM controller is rated for 125C TJMax:

Вот адаптер для лазерной резки, установленный на материнской плате:

Процессор расположен ниже рамы, здесь я повторно использую оригинальные подпружиненные винты.

С этим адаптером @Alucard1729 вокруг процессора достаточно свободного пространства:

View attachment 185021

Я использую здесь DeepCool AS500, я прикрепил его монтажные зажимы непосредственно к раме, и монтажное давление кажется достаточным:

View attachment 185022

У него есть собственные подпружиненные винты, которые DeepCool, похоже, теперь стандартизировали на всех своих воздухоохладителях.

Крупные планы того, как я прикрепил оригинальные подпружиненные винты с помощью C-образных зажимов, которые прилагались к ним:

View attachment 185023

Кронштейны Deepcool крепятся с помощью простых винтов M3 и любых гаек, которые у меня были на тот момент:

View attachment 185024

Я думаю, что это гайки с накаткой, которые идут в комплекте с AS500, но подойдет любой винт M3 с круглой головкой + гайка.



У меня башня работает нормально. если в системе есть еще один вентилятор (впускной или вытяжной), этого должно быть достаточно для охлаждения VRM. VRM рассчитаны на 150C TJMax, контроллер VRM рассчитан на 125C TJMax:

Thanks for the quick response. There is also a question about the processor. I tried to depict it in the picture. The height of the processor board (1) is higher, lower or at the same height as the processor chip (2). Is it possible to use an area larger than the processor area? on a standard cooler there is a protrusion (3) on the contact area for the chip. The flat area of the cooler will not rest against the processor board (1)

 

[rsaeon]

The CPU die is a fraction of a millimeter higher than the surrounding area, just like the PS5 chip:



The AS500 I used has a cold plate that covers almost the entire chip but contact was only made with the CPU die:

 

[Vazyaba]

Кристалл процессора на долю миллиметра выше окружающей области, как и чип PS5:

[ПРИЛОЖИТЬ]185057[/ПРИЛОЖИТЬ]

AS500, который я использовал, имеет холодную пластину, которая покрывает почти весь чип, но контакт был только с кристаллом ЦП:

[ПРИЛОЖИТЬ]185058[/ПРИЛОЖИТЬ]

Do you think this heatsink is enough to keep the processor temperature up to 90°? Now under load it reaches 102°.

Is it dangerous to stain components near the processor chip with mermopaste?

Does it make sense to apply thermal paste along the contour of the processor case (1), adjacent to the base of the heatsink?

Thank you for your responses!

[rsaeon]

Since the CPU die is exposed, thermal paste is only effective on the die, applying extra won't help. Most thermal pastes is also non-conductive so it's okay if extra spills over the sides of the die.

Any cooler would be better than the stock one, even that little one with two heatpipes. However, it uses a clip for mounting so I would be very careful in mounting it since the die is exposed here. I would suggest you find a cooler that doesn't use clips as mounting.

I've noticed a tiny crack on one of the corners of the die because I was careless in how I removed the cooler for these photos (you should loosen each screw a little bit each instead of completely at once).

Maybe instead of replacing the cooler, you can try replacing the fan? You can add a 120mm fan with an adapter:

Or you could take out the fan from the Cooler Master i70 and use that instead:

Can these be mounted on itx board clippers?

What's a clipper in this context?

Forgive my made up eng , I meant can this board be used in regular itx cases?

Yes, it's a standard mini-itx motherboard.

What is the idle power consumption on this kit?

 

[Vazyaba]

Hello, I have modified the cooling system. Installed a tower radiator. Developed and 3D printed an exclusive motherboard cooling system. Previously, the processor overheated and reduced performance to 2600Mhz, but after modification it operates at the factory frequency of 3500Mhz. The operating temperature of the video card also decreased. The cooler mount is 3D printed from PET-G plastic.

 

[Vazyaba]

Hello, can you please tell me if it is possible to buy a AMD 4700S Desktop Kit now with international delivery and what is the price?
