Hi Everyone,

Tugm4470 issued me a FedEx Waybill and Commercial Invoice for the return of 4 x 32GB 3200 RDIMM memory, to be exchanged for 2 x 64GB 2933 RDIMM memory.

I then purchased 4 x 64GB 2933 RDIMM memory and when they arrived I swapped out the 4 x 32GB modules and returned them using his supplied paperwork and the packaging that sent the 4 x 64GB modules. Everything was very well packaged and paperwork was in order for the return.

I dropped it to the local FedEx shipping facility and there was a delay of about 4-5 days at the Chinese customs because the Commercial Invoice which Tugm supplied did not provide anywhere near the level of information required by the agent (item type: GIFT and description: MEMORY). So I spoke to FedEx, got the case number and received their email with the details added to the initial case description and created a new Commercial Invoice and sent the Word doc and PDF to Tugm. I asked if he could contact the agent as requested in the FedEx case - the agent had included his email and phone number in China.

Tugm said that he will contact FedEx, which he did and eventually it got sorted and the package was delivered to him. I had kept him updated on things and asked for confirmation that he had received the package, which he did.

TLDR: it is now 7 days since Tugm confirmed receiving it and he has not responded to my request to progress (so that I can purchase more memory). The memory was in pristine condition just as it was shipped to me (used) and the expectation was that he would test and when happy I would use the credit/refund to purchase more. A pretty exchange process.

During these 7 days I sent more messages to Tugm, asking him if he could give me store credit to purchase more of the same 64GB 2933 RDIMM memory he sent me in the last shipment. Still he did not reply and so I then asked him that if that is too difficult perhaps he could just refund the money (minus the agreed amount to cover the return shipping) and I will then make the purchase. Still no reply.

I've asked him to please respond so that we can get this purchase completed, as I need to increase the memory in my homelab (Epyc 7452 on Supermicro H12SSL-i, purchased in October 2023 from Tugm).

Tugm4470 might be unable to respond but if anyone here is in communication with him can you please advise me and perhaps ask him to contact to make the purchase and get it shipped. He knows me as "nw.we_94". I also intend to purchase from Tugm another 2 x 64GB modules in the new year to max out the motherboard with 8 x 64GB. Thanks guys.

FYI here is my communication since Tugm's last response:

Hi Tugm, thank you. I was wondering if there was an issue with eBay, too. I don't have much experience with it so didn't know what to expect. Their chat tech is rudimentary at best.

I didn't know you were a member of STH but should have checked and sent you a private message. In future I can also send you file attachments via STH direct message instead of via email.

Thanks to the STH member who was able to reach out to Tugm.

Just today tried sending a message to tugm4470 in eBay and the message was blocked. eBay blacklists some words or combinations of words. Good thing STH works just fine. :)

Just received the two new 64GB 2933 MHz memory modules from Tugm after moving slowly across the planet during the Christmas and New Year break. Well packaged as always and identical part numbers to the four modules already sent from Tugm:

Look at all that beautiful memory:

Thanks, Tugm!

Update on these components purchased from tugm4470 — built as a Workstation has been running flawlessly 24/7 since this thread was started. Running Proxmox 9.1 currently, with Gnome Wayland desktop. GPU is AMD Radeon 5700 XT.

About to rebuild with NixOS running Xen hypervisor and switching to either Niri or Hyprland 0.55 (first-class on Nix) desktop. All using pure Nix and Flakes with no dependencies to avoid as many abstractions on top of Nix as possible, such as Determinate Systems, Devenv or Devbox. Only Direnv with Nix-Direnv for caching and protection against garbage collection. NixOS on Stable, Home Manager on Unstable. Separate unprivileged account for AI. Shared developer environments running in "/srv".

Xen is a well established first-class citizen on NixOS and the combo doesn't run an integrated VMM, like QEMU or Cloud Hypervisor. However, Xen can run "xen-qemu" which is a sandboxed version running as a subdomain so if a compromised VM guest were to break out via the VMM it won't have access to dom0 like it would on QEMU KVM.

Xen setup and configuration is integrated into NixOS with Nix and Flakes. Fully reproducible. Monitoring will be Prometheus & Grafana with Xen plug-ins — all first-class on NixOS with Nix config.

All VMs will run NixOS, with each VM containing Linux Containers running a cloud minimal NixOS, possibly NixOS-ng. Caddy for reverse proxy, OpenBao for secrets management, OpenTofu for Terraform integrations. NixOS nftables for Nix configured Firewall monitored via Prometheus & Grafana (otherwise will run ipFire in a VM).

Not sure what to use as LXC runtime inside the VMs. Tempted to use pure NixOS containers with OVS switching. Otherwise Incus, or possibly run Podman OCI containers instead of LXC. Podman is also first-class on NixOS.

Developer environments will be primarily Elm lang with Elm Pages running on Lamdera with Roc language in the future as it becomes stable after the compiler rewrite from Rust to Zig.

NixOS Admin and Claude are running Bash-only as login shell and Nushell interactively for the human user.

Moving from retail hardware onto enterprise has been a great experience and would suggest that Epyc is the sweet spot for most home and small business solutions. Very price competitive against Threadripper.
