Perfect

CachyOS Handheld edition + https://github.com/redbeard1083?

Is there anything in that toolkit that’s obsolete or is there anything new that's missing?

Has somebody tried the BC-250 GFX1013 compute queue fix to improve overall performance in games?

Hey everyone!

After seeing a lot of people discussing on the best way to feed power to our boards, I decided to run some tests :

How much power can we (safely?) pull from the 8-Pin connector ?

I'm not responsible for any harm or damage if you want to try this yourself !

As we know, MOLEX is rating those connectors to 150W max.

For this test, I used :

- BC250 running at 2100Mhz on all 40CU, 6 CPU cores non-OC.
- Open fins heatsink + Arctic P12 Pro
- custom VRAM heatsink + Arctic P12 Pro
- GPU 8+8 pin Cooler Master PSU cable (higher wire gauge than single 8 pin)

I ran a stress test with FurMark in 4K resolution and frequently checked how well it was running

This setup was pulling more than 300 Watts from the grid.

The results :

The board quickly heated up at the beginning, which is absolutely normal.

However, I was surprised when I saw nearly no temperature evolution during the following 30 minutes.

As you can see on the images, the 8-Pin connector and the cable stayed pretty chill (barely warm to the touch)

The 50°C+ hotspots are not related to the power connector. It is actually the PCB dissipating the nearby VRMs heat.

After more than 30 minutes, I decided to stop the test as nothing evolved.

Following the results, It might seem relatively "safe".
However, this test was done in open air environnement. The results could be different if done in a case.
So I'm not recommending to do so except if you are aware of the potential risks.

The next step is to try again with unlocked 8 cores CPU !

Just finished my first BC250 build!

(Case https://cults3d.com/en/3d-model/gadget/bc-250-atx-case-steam-machine)

MSI 650W Bronze PSU + 3x Arctic P12 Pro fans.

Currently running 38 CUs and 8 CPU cores unlocked, and everything has been working incredibly well so far. At idle, I'm sitting around 55–60°C with the fans practically off, which I'm really happy with.

This has been an incredible build and I'm absolutely loving the experience with Bazzite. Honestly, for the money, this thing is amazing.

I do have one question, though. I also have a Steam Deck, and there are some games that run perfectly fine on the Deck but won't launch on the BC250. Is this related to the hardware/driver configuration?

For example:

* Red Dead Redemption 2 → black screen

* The Crew Motorfest → crashes on boot

* Resident Evil Requiem → runs incredibly well

* Forza Horizon 6 → also runs incredibly well

So I'm wondering if there's something specific to the BC250 that could explain why some games work perfectly while others don't.

I'm also thinking about building a vertical case, with the PSU at the bottom and the BC250 motherboard above it, trying to replicate the look of an Xbox Series X.

Do you think this would be thermally efficient, or would I be better off with a more traditional horizontal layout?

Never play Skyrim in my life so this is my first play through ever. I tried but the original graphic turned me off. So I tried installing modern graphical mods but nothing worked. I use the 10 graphic mods and most of them are community shader mods (as suggested by Gemini). I use this video https://youtu.be/u6jnonnxrVQ?si=9R4A\_Bg9rQSgw83U as a baseline. What actually went wrong? Can someone help me all the mods that are compatible with Bazzite and BC250. Thank you!

so i got two of these and the assorted setup, and i opted for blower fans for maximum airflow while still being able to change my mind and not permanently alter anything.

i plan on not overclocking anything until a more permanent solution is found, but you know the saying:

nothing more permanent than a temporary fix

parts list:

2x bc-250

2x apevia 400w psu

2x - https://www.amazon.com/dp/B0F2SS4TXW loud ass blower fans

2x - https://www.amazon.com/dp/B0FVSDKQ5W this is the 24 pin adapter with switch and 12v barrel plug leads

1x burnt out dryer heating element from my best buy dryer

1 scrap mdf board

1x dremel

too much time

both are 40CU, one is 8-core, the other stuck with 6.

i plan on using those 12v plugs to power my monitor or other small drain stuff with usb-c with an adapter: https://www.amazon.com/dp/B0FD735LFG

probably gonna adapt the 6-core one into an arcade cabinet soon

edit: I do wanna stress that this is not the permanent home for these, lol

or cooling solutions, more than likely.

I tried removing the tops of the fins.

I had trouble because the seller had already tried doing it before; the aluminum was weaker at the edges as a result, which made things difficult.

I plan to use a 12V, 12,000 RPM Tozz mini rotary tool with the blue grinding bit to remove the burrs. Should i?

TLDR: Is anyone using the meanwell 12V 350W, how noisy is it??

Hello all,

I have access to 3d printers and I have completed this build:

https://makerworld.com/en/models/2780951-amd-bc-250-industrial-style-compute-case-v1-0#profileId-3090664

Printed everything in ABS. The built itself is quite nice, although there are some minor nuissances (left unnecesary supports, holes too small for some screws, etc). Also, I think that having cables protruding from BOTH sides of the case is at least debatable.

My question if anyone has built it and have it working, how is the MeanWell 12V 350W working? Mine starts the fan after a few minutes and it will NEVER stop afterwards, also, it is painfully, awfully noisy.

My ambient temp if pretty high at 34ºC at the moment, so, sure that's a factor to take into account, but is this really the way this powersource works?

I will have to move to a bigger ATX dessign if this is the case (pun intended).

The BC250 is surprisingly nice, although I installed the BC250_P5clv_8core_v2.ROM bios and I can't for the life of me find a simple "boot from USB" option/command in there.

I have managed to install cachyOS, I would like to test it with steamOS but it does not recognize the usb with the image.

Today I cleaned my BC 250 (since I'm a fool and removed the fins from my heatsink on top of my motherboard because I didn't know how to heat it up and remove the heatsink). I used a lot of canned compressed air for both the heatsink and the motherboard. After checking it thoroughly, I didn't see any dust and the thermal pads looked great.

Some of the photos are from before I cleaned it, and they were tiny little pieces of aluminum, almost like dots. When the power supply and new thermal paste arrive, I'll take another look and then I'll connect it. I hope nothing bad happens.

Still work in progress these are vision-2 renders, this is my first time designing and printing something big like this, If you have any suggestions please let me know.

The real print come out almost good, it's based vision-1, it was few mm short, too tight and required sanding from the inside to make the board slide in, it's mostly fixed with vision-2.

It supports 2x120mm fans on the heatsink up to 25mm thickness, there is enough space for another two or one 120mm fans on the VRAM up to 15mm thickness, but I didn't model a mount for them.

Required print volume is under 180x180x180mm³, 4 parts, front, middle, back-IO, and fans mount.

Other required parts, 4xM34mm, 4xM36mm screws, 4 hex nuts, 4 Inserts, 16mm latching switch.

Unfortunately the one at $166 is going in/out of stock. The same seller is selling them for $196 and that one is staying in stock. With the coupon stacks and rakuten cashback, it's still a decent deal - but if you manage to get lucky and see the $166 one in stock, it's a no brainer.

$196 link: https://www.aliexpress.us/item/3256810471692576.html

For the coupon stuff:

Paying with paypal = $15 off stackable coupon

$32 off coupon for purchase over $159: IFPIQ0Y5, IFPEOURC, EVO32A

Rakuten enabled = 19% cashback

I got pretty lucky, and once the rakuten cashback hits that means I basically snagged a bc250 for $106. YMMV, GL! : D

I've already removed the cooling brackets; I'm waiting for the power supply and fans to arrive. For now, only one fan will arrive; the rest will arrive at the end of the month. Now all that's left is to buy compressed air and isopropyl alcohol to clean the aluminum shards. I'm really happy to finally get it working.
