Your battery is going to suffer because of the extra ram as well.

I don't know your workloads, but for me personally 64 GB is the ceiling buffer on RAM - I can run entire k8s cluster locally with that and the M5 Pro with top cores is same CPU as M5 Max. I don't need the GPU - the local AI story and OSS models are just a toy for my use-cases and I'm always going to shell out for the API/frontier capabilities. I'm even thinking of 48 config because they already have those on 8% discounts/shipped by Amazon and I never hit that even on my workstation with 64 GB.

No, it won't. The power drain of merely refreshing DRAM is negligible, it's no higher than the drain you'd see in S3 standby over the same time period.

I thought my Z620 with 128GB of RAM was excessive! Actually, HP says they support up to 192GB of RAM, but for whatever reason the machine won't POST with more than 128GB (4Rx4) in it. Flawed motherboard?
