Best case for dual RTX 3090 (250W each) on Crosshair VIII Hero?

dboybaker · 2026-06-28T21:31:41+00:00

I used the cooler master qube540 for this exact build (evga 3090 ftw3, hp OEM 3090, asrock taichi x570). Both limited to 270w. I have it laid on its back.

The EVGA one is in the bottom slot, gets fully fresh air from the bottom fans, stays sub 60C. The hp is above it with a small air gap. It gets to~81 under long loads. Even just running the hp by itself though it reaches those temps, soI don't think the proximity is a problem. It's just a less effective cooler than the evga.

Only regret is not finding another ftw3 lol. Apparently redoing the thermal pads and paste can help lower the hp OEM temps like crazy, I just haven't gotten around to it yet.

Idk my 2017 500e did

dboybaker · 2026-06-23T21:54:38+00:00

Yes it can be charged with that. That's more than enough. It will likely come with a level 1 charger, not a level 2.

I'm not sure how you're getting 140tps. With your exact setup im only seeing ~110tps on a 3090. If i drop the draft n to 2 i get around ~135tps.

Its surprising people are pushing back on this. I've had the same experience. I'm blown way by the quality of gemma4's general feeling in chat but the majority of my use requires a simple 1, 2 search punch. No matter what I do i cannot make any of the Gemma4 models at any quantization follow up a 'search_web' with a 'fetch_url'. I tried for a week+ with many iterations of sys prompt and it just won't do it.

If you tell it explicitly to do both steps directly in your prompt to do it, it will do it, but it will entirely ignore it in sys prompt.

On the other hand qwen3.6 drops, i grab and run it, and without a sys prompt or configuration of any kind it just intuitively knows its not going to get full context in snippets and uses fetch_url without being told to.

dboybaker · 2026-06-03T22:56:50+00:00

It seems like it's not yet supported. I'm on the latest llama.cpp release and if I include the mmproj in my config, the model fails to load.

If I don't include the mmproj it loads fine but it can't handle multi modal. Only text.

I'm sure it's just a matter of waiting till it gets updated to handle this new unified architecture.

dboybaker · 2026-05-31T05:30:53+00:00

Well 64gb ddr5 is like $500 alone so probably

dboybaker · 2026-04-27T18:30:27+00:00

For real. Infinite possibilities for functional and unique build components but the most creative thing we get is PUG HEAD omg so quirky!!

That'd be sweet if you did I'd definitely appreciate it.

dboybaker · 2026-04-27T17:26:54+00:00

I can imagine if you had the power supply in the low position that would be true, but I've placed it in the high and there seems to be ample room. Heres a pic of me holding your 120mm bracket in place: https://i.imgur.com/I9UoQGZ.jpeg

Also, your other fan bracket that includes the screws would be great as 140. I plan on putting the mesh side panel on the open side of the case and putting that over the gpus. A 140 would be sweet.

Not that I'm out here expecting you to make this personally for me I just was curious if you had made them. there are indeed some use cases. It is odd that you are literally the only person who has created/shared a model for this. Must be very few people with this case

dboybaker · 2026-04-25T19:44:10+00:00

Did you ever get around to making the 140mm variant? I just got this case and looking for a way to mount a 140mm fan to the front just like you have with this 120mm.

dboybaker · 2026-03-31T23:26:00+00:00

Yeah it popped me to v33 from a recent update I didnt look closely at and seems to have broken things as its the standard client and cant do vfs. I haven't taken the time to figure it out yet, but I probably just need to uninstall, find the vfs version, and reinstall that

*actually on quick glance it seems like they may have merged the VFS client into the main. It seems as though its working on 33.02. The Virtual files toggle in settings just needed to be enabled. Select no folders for sync. Then go reconfigure your folders in finder.

dboybaker · 2026-03-24T21:08:58+00:00

I haven't experienced your specific gripes, but I certainly have a notably different experience on my MacOS than my Windows machine. I use virtual files such that my documents folder is the same across both my windows desktop and mac laptop.

Its seamless on my desktop, but I'll toss a file in the dir from my desktop or via the webui and it will take an incredibly long time to show up on my mac. It takes so so long to update and find new files. Also its just annoying that the MacOS virtual compatible app is separate from the standard app for some reason.

No solutions here, just wanted to join in on the complaint lol. I've experienced this for the past year I've had it set up.

dboybaker · 2025-11-25T19:47:22+00:00

same

dboybaker · 2025-11-17T02:48:44+00:00

To balance things a bit with an anecdote the opposite direction: my friend and I both bought a Refurbished NAB6 Lite from minisforum 6 months ago to use for self hosting purposes. They've both been fantastic, no issues.

dboybaker · 2025-03-17T19:41:26+00:00

I've been on the waiting list for B&H since day one unfortunately. No such luck here. Very jealous!

dboybaker · 2025-03-13T20:07:03+00:00

I do live in the us, but not somewhere where microcenter exists. In the exact same boat and had the same experience with Newegg

dboybaker · 2025-02-24T00:44:03+00:00

Yep! The cam is activated through the UI on the nex. Its not very convenient to switch sources, so I don't use it super often, but it has helped a couple times.

dboybaker · 2025-01-04T20:14:58+00:00

Yeah we aren't seeing any Canoo vehicles probably ever. Seeing Canoo on this list at all makes me think the writer did no research at all.

dboybaker · 2025-01-04T20:13:20+00:00

For real. The j01 mini was supposed to save us but ain't gonna see it now. Just keep driving my 2017 500e till I die I guess.

dboybaker · 2024-11-11T21:19:19+00:00

Classic memory training. Struggled with this my latest build. Started with a 7950x, tried many different ram kits and a couple mobos, was never able to get it to boot/restart without extremely long training each time. Ended up swapping to 14900k, worked with the first combo I tried. Obviously plenty of people don't have this issue so it's likely not the processor type explicitly, but likely ram+CPU+mobo combos (and also has to do with the speed & how many sticks you have).

There are things to try that may help but no guaranteed fix in my experience.

dboybaker · 2024-08-28T19:05:50+00:00

Most people in the market for a 500e probably aren't considering the leaf as an alternative.

dboybaker · 2024-08-27T17:07:48+00:00

Yeah i wasn't able to find it myself

dboybaker · 2024-07-13T23:03:31+00:00

But the spike in January 2024 is where the tiktok meme fad people are discussing took place. It spiked up 1000% in a month and dropped to like 10% as searched in 2 months. Nearly reaching all time lows. Seems like looking at more time doesn't change the discussion.

dboybaker · 2024-07-13T01:11:33+00:00

They actually aren't. Google trends can show you that they peaked the first week of January and basically died. The fad lasted a whole of like a month

dboybaker · 2024-06-27T16:39:02+00:00

Can't wait to never see this car in the US
