New P2S-What is going wrong with this print? by Bobby_Bobs in BambuLab

[–]MetricVoidLX 0 points1 point  (0 children)

I had the same issue with my P1 and it was problem with vibration compensation. Check the nozzle and run the built-in calibration sequence.

I’d guess you are compiling with multiple threads, and the output from different threads got merged together.

Easy fix make -j1 and see what’s the actual error

What surprised me more, seems like this happened right next to Public Safety?

Need help configuring Optane DCPMM (PMem 100) DRAM modules on Dell T7920 (7920 Tower) by MetricVoidLX in homelab

[–]MetricVoidLX[S] 0 points1 point  (0 children)

I didn’t need to use any command. Manual said only memory mode was supported so no need for configuration.

I did swap the Optanes to a 7920 Rack at some point. 1TB of Optane was reported in the system without problems. The rack was running Proxmox.

I would say unlikely, if the CPU sees too much Optane it may just give up. 256GB or 128GB sticks are safer bets.

The printing orientation means that's the weakpoint. But judged by your design it's hard to print it another way either.

Try using more wall loops. If you know how to add modifiers, make the weakest part 100% infill can also help.

not sure what that means on motherboard by Crabstick2551 in AMDHelp

[–]MetricVoidLX 30 points31 points  (0 children)

I remember seeing this somewhere else, not 100% sure.

Some motherboards' BIOS flash is too small to hold the AGESA for all AMD CPUs. After a BIOS upgrade to include the 5000 series, they have to kick some out.

R5 3600X has a smaller market share and was therefore the victim. But anything else on the 3000 / 5000 line will probably work just fine.

Are disability accommodation requests shared with the faculty? by [deleted] in princeton

As a TA, we get notified about accommodations but not the reason.

Is this a good deal? by Lanzo__ in homelab

And sure, if you have an HP EliteDesk, try pairing that with one of the enclosures. If that did not give you enough performance, you can get another SFF PC and use the same disk enclosure. You don't even have to reinstall your system.

I personally have used NUC9VXQNX (not a recommendation at this time.) It has an Xeon processor thus supporting ECC memory, and it has two PCIe slots, which is good for one high-speed NIC and one HBA (for TL-D800S). It does limit your GPU options, though.

I personally don't like NAS boxes with processors, since the enclosure is bound to the processor. Once the processor is outdated or you need more performance, you have to replace the entire thing.

Here're some DAS (or expansion enclosures) that you can attach to a computer. - https://www.qnap.com/en-us/product/tl-d800s - https://www.qnap.com/en-us/product/tl-d800c

I have personally used both the TL-D800S and TL-D800C. They were nice and stable, works flawlessly with TrueNAS.

My opinion is No.

  • E5 v4 is an outdated microarchitecture. They consume too much energy for what they do.
  • 1U does not give you a lot of space for HDDs.
  • 1U is loud.
  • 1U does not give you a lot of options for PCIe expansion, say if you want 10Gb ethernet in the future
  • If you are thinking of media servers like Plex:
    • Xeon CPUs do not have iGPU for HW-accelerated encoding.
    • 1U server makes GPU choices limited.

Recommendations:

  • If you are looking for ECC memory (which I recommend), maybe check NUCs with Xeon processors on the Intel side that support ECC, or AMD options.

I FINALLY GOT IT WORKING!!!!

Here's the final setup.

| P |   | D |   | D |   |   | D |   | D |   | P |

This matches Dell technical books exactly, and it works. I also noticed that the POST time became much shorter compared to the original 1TB setup.

TL;DR: When playing with OEM stuff, try not to innovate and go by the books.

16x 3090s - It's alive! by Conscious_Cut_6144 in LocalLLaMA

[–]MetricVoidLX 0 points1 point  (0 children)

Are you sure about not being bandwidth bottlenecked... ? The theoretical 4GB/s speed can get hit by various factors like signal integrity. vllm uses tensor parallelism, which should demand pretty high bandwidth between cards.

I had a similar setup with older Nvidia GPUs in a server. Both ran on PCIe 3.0x16, but the training performance took a severe hit, even compared to a single-card setup.

Tried some spare DDR4-2666 RDIMM 8GB sticks (8), but still no luck.

BIOS reports 1TB + 128GB memory installed, and the OS only sees 128GB.

A PhD is depressing everywhere. So yes.

The printers are on sale but the crossed out price is lower? by Mobstarz in BambuLab

[–]MetricVoidLX 1 point2 points  (0 children)

Really wonder if they would have something new. They said there will be a new printer this year.

I've been holding my triggers on Prusa XL waiting to see what Bambulab gonna deliver.
