The $342 Crucial kit is kinda a no-brainer for 128. Its timings aren’t great when overclocked, but it’s 5600 MHz out of the box, low voltage, and significantly cheaper per gigabyte than many 64GB/96GB kits. See for yourself:
I appreciate it. I’m not going to overclock. I used to do that but these days I value stability over maximum performance. I’ll go with your suggestion, thank you.
You don’t have to overclock, but I’d at least look at your mobo’s settings. Many mobos set really, really bad, non stock settings by default, especially with XMP memory.
An example: they might default to 1.3V VSOC which is absolutely a “default overclock” and is going to make idle power skyrocket, and your CPU potentially unstable because infinity fabric doesn’t like that. For reference, I personally wouldn’t go over 1.2V VSOC myself and shoot for like 1.1V.
Also, if you don’t turn on XMP at least (aka the RAM’s rated speed), they will run at some slow default and hurt your inference speed rather significantly.
I’m have to check. It’s a pro, not air, but I think it’s only 40GB total. I’m really new to Macs so the memory situation is unclear. I requested it at work specifically for its capability to run local AI.
It is. I’m running this model, with hybrid CPU+GPU inference, specifically: https://huggingface.co/Downtown-Case/GLM-4.6-128GB-RAM-IK-GGUF
You can likely run GLM Air on your 3060 desktop if you have 48GB+ RAM, or a smaller MoE easily. Heck. I’ll make a quant just for you, if you want.
Depending on the use case, I’d recommend ERNIE 4.5 21B (or 28B for vision) on your Macbook, or a Qwen 30B variant. Look for DWQ MLX quants, specifically: https://huggingface.co/models?sort=modified&search=dwq
I’m going to upgrade my ram shortly because I found a bad stick and I’m down to 16GB currently. I’ll see if I can swing that order this weekend.
To what?
64G would be good, as that’s enough to fit GLM Air. There are some good 2x64GB 6000Mhz kits for 128GB as well.
I’ll see about 128, then, but I’ll probably do 64. Just depends on cost. Any recs?
For DDR5? Depends how much you care about latency:

The overclockability matters even less if you are on a 7000 series CPU.
I got the 1.25V Flare X5 kit because I wanted tighter timings for sim games, albeit at a MUCH lower price ($390) than it is now.
RAM prices seem to be rising (hence the price of my kit spiked by $200), so now is not a bad time to buy.
