As some people may know, the Pi people made a version of the Raspberry Pi 4 chip that is installed on a CM3 compatible SODIMM-200 board. Came out late last year with the usual 1GB of memory and there was talk that they would also release 2,4,and 8gb memory versions. I did buy one on Ebay with 1gb memory and yes they work, they work well, they are much faster than the 3+ units, but of course the big problem is they only have a Gb of memory so they tend to hit swap hard when doing anything interactive. The other issue is they only have 100mbps Ethernet (boo!) so that's always going to be a bit of a choke point. In March, Newark electronics had the 8gb memory 32gb storage ones on backorder, so I ordered a pair of them for $75 or so each and forgot about it. Part number is: cm4s080032 They just arrived. Yes, they have a true 7.8gb of memory. Yes, they do work in my TPi 1, yes they are blazing fast, and yes this is a significant game changer for this board. Now I can finally run real memory intensive applications and maybe a full install of K8s. So if you have a Turing Pi 1 and want to boost up the cluster to some real memory amounts, it's possible. The next thing I'm going to try to find is a pair of these with 0gb of disk space so I can use them as my bitcoin node and internal SAN (both running 2tb SDHC cards). If anyone has a lead on this model let me know 🙂

I tried googling the part number, but I got no results.

Looks like it’s CM4S08032

I have 28 CM4S modules (with 1GB each) across 4 TPi1 boards in a cooler master case. Indeed, the modules with higher RAM would be great for k8s. Too bad the TPi1 boards are no longer produced.

Indeed. The TP1 board turned out to be pretty cool. Thanks for posting the part number Steve, they also seem to have the 4gb one with no EMMC for a lot less. I just ordered two for my system to replace some 3+ slugs. 4gb of memory is plenty for a SAN or bitcoin node.
