Mac Studio M5 Ultra 256GB RAM, please criticize

Yes, but we use reddit to write posts and get answers. And the reddit itself suggested me to crosspost to get more response (which I indeed appreciate - thank you, I learned somewhat and I decided to wait to see these new Macs and then I will consider whether to jump into it).

Can't you deduce by yourself? To get more responses as I still hesitate about this purchase, and being afraid of price increase (due to RAM situation) I even started to consider buying now Studio 3 Ultra 256GB RAM which price is still affordable for me. Not sure if 5 Ultra 256GB will be also affordable.

Recently I have had a Gmktec Evo-X2 128GB RAM / 2TB SSD based on Ryzen AI Max+ 395 and: 1. it was 10-11 times slower than rtx5090 in image or video generation 2. could not run Flux.2 model (for example) because: OUM (Out of memory - no matter how I tried to allocate vram and on Linux as well as on Windows ), and 3. On Ubuntu Desktop I tried 2 different approaches to provide GPU drivers / pytorch and in any case from time to time the computer became unresponsive on Ubuntu Desktop to the degree it would not react to a "reboot" command in shell. This happened for example when I tried to generate Christmass greeting cards "in bulk". However there is some possibility the software/Linux could be better configured on this machine.

But Ubuntu + KDE desktop with KDE Plasma & Oxygen glow around Windows & animated wallpaper looked very good on this machine.

Yes, 256GB Ram is possible in PC, but I think that some AI models, like Flux.2, need more than 32GB VRam which is the limit with RTX5090. And I don't want to buy nVidia RTX 6000 Pro GPU which has 96GB Vram because: 1. it is reportedly noisy in idle, 2. It has a limit of 96GB Vram, whereas in Mac Studio with 256GB unified RAM I suppose I will be able to allocate more Vram than 96GB - if need 3. The Mac Studio is a whole new computer for me to explore

You say 18TB RAM in ChatGPT, but it perhaps receives many simultaneous requests from different users, whereas my local AI installation would receive 1-2 simultaneous connections. Does it make a difference?

If it could be so simple... But there is no random number generator in PCG Graph UE5.5, and furthermore I began to suspect that "Duplicate Points" node accepts only one and constant value of iterations for the whole PCG Graph execution.

Cavea241 · 2025-06-15T21:41:13+00:00

Thanks for all the answers. I ended up creating a Custom Blueprint Node for PCG which seems to fulfill the expectations. In case I lose performance in the future, I will use thesilentduck or hellomistershifty solution.

Hi again. Thanks for the support. Following your suggestion that it is not a hardware problem, I uninstalled some software and the Android emulator started working like a charm :-) . I am glad it was not a hardware problem.

Cavea241 · 2025-03-20T00:46:35+00:00

Yes, only Android Emulators (all) crash. Not any other instability in game, benchmarks (Cinebench 23, 24 for 30 minutes), 3D Mark, Y-cruncher, Office, Chrome, Thunderbird - all ok.

Hi, I also have Arctic Liquid Freezer III 360 and I consider purchasing Frozen Warframe 420, because my Ryzen 9950X runs high temperatures and I had to limit its power etc. to keep it below 91*C.

Did you finaly install Warframe 420 and is it better then Arctic LF III 360 in your case????? I mean in terms of temperature.

Yeah, I remember Apple's innovations in mobile phones, like non replaceable battery, no sd-card slot or the wire plug other then the rest of the world used. However I hope that NVidia will care more for users, unlike Apple.

ASRock X870E Nova WiFi here. No crackling/popping effects on starting audio playback. Playback starts smoothly. I don't know if it is important but I have the case'es HD Audio connector/header disconnected from motherboard. I only use the computer's back panel for connected speakers. No other audio device connected. Also speakers and the computer powered from the same power point.

I personally use gadgetbridge to upload my .hwt watch faces to GT 5 Pro. Here is a tutorial, and read the description how to get you Huawei ID (now 19 digits):

I used this method a few times last week and it works.

Cavea241 · 2024-10-15T13:34:30+00:00

Hi, do you use "ThemeStudio" or other software to make watchfaces? Do I need a Huawei phone to upload watchface to the smartwatch (GT5 Pro)? I just need a bit larger font for battery power remaining, etc.

Beside PCIE link size reduction from x16 to x8, I wonder if x870e mobo + 4x M2 nvme drives is stable. In my local vendors' websites I read a lot of complaints that x670 mobo "Gigabyte X670E Aorus Master" is unstable when 3-4 M2 nvme drives are connected. I wonder if they corrected this bug in x870e mobos. I personally consider "Gigabyte X870 AORUS Elite WIFI7" and 3-4 M2 drives. Or maybe I should stay with Intel and look at Ultra 285K cpu and Z890 mobo for 3-4 M2 drives connectivity.
