Good thing opus 4.6 just got released. Drop 50 bucks into the token grinder and give it a shot lol Honestly though RDMA is basically line rate in my testing so might be worth your time to just direct cable a pair of 400G nics together. What do you need all that bandwidth for if not AI?

Dude, if I can figure it out you can too. There isnt that much to it. just ubuntu 24 + install the p2p driver + tweak a couple bios settings and you are off to the races, instant bandwidth spike and latency reduction. Altho depending on the software you are running (it needs to actually take...

My experience with SM support has been rather bland. It was very much "yep. sucks. too bad you don't spend enough money for us to care." My last SM board was July (because they had the first and only board for months designed for the latest chip I wanted) and I will be making a point of...

Those 80mm fans are either going to be tornado sirens (high static pressure), or if you replace them with desktop ones (low static pressure), not move nearly enough air to keep the system cool under load. But it sounds like a great learning opportunity.

I would not count on anything built for a datacenter to be low power or quiet. Supermicro will sound like a jet engine and fight you every step of the way trying to slow those fans down. If you are willing to drop the hot-swap requirement, grabbing a cheap rosewill case will meet your needs...

Are you sticking with 3.5inch disks or going to 2.5inch ssd? Form factor and power draw matter. What are you using the NAS for? Is 1g/10g plenty or will you be going 100g+ with nfs/rdma for virtualization/ai/etc?

In my experience the Epyc QS chips have a lower boost clock making their performance not comparable with retail benchmarks. Additionally in some boards, the BIOS does not provide topology information to the kernel with regard to chiplet core/cache locality for those OEM SKUs resulting in...

Well that answers the workload question. You are in HEDT terroritory. Check out the benchmarks for compile times specifically for that:

that 4565p is single socket. Those 16 cores of zen5 are really shockingly capable. If you have a specific workload though you need to complete in a set amount of time, renting a machine for a couple hours in different clouds can be quite informative to figure out what the performance profile on...

I have never had an AMD ES/QS chip boost to full retail clock speed. And if you have that many cores fighting over two sticks of ram crossing between CCD's its gonna be obnoxious. Especially coming from a chip with 3d vcache and all memory channels populated. To be completely honest though if...

That is exactly the lesson I learned with my first rig design using an asus w790e-sage board with traditional 7 slot layout. After doing the math on retimers for every slot beyond the second or third for signal integrity, i adjusted course and grabbed one of these...

CPayne's switches do negotiate gen5 and my rule is, minimize cable and pcb trace distances, the latter being the very most important. I went through a tremendous rig redesign to reduce every mcio cable to <50cm and replaced all my risers with ones with shorter traces. If you are going to use a...

Oh no!~ How terrible! What specific auction site was this so we can all be sure not to use it in the future... ;D Also, can you take a whole bunch more pictures of this thing for future reference? There is scant few details online about the specific model you seem to have. And those PCIE...

According to the manual: I dont see any indication from the block diagram there is any sata supported on the MCIO port: The u.2 port is right next to the sata ports: Which looks like MiniSAS HD SFF-8643: Amazon.com

In case anyone else is ever lucky enough to come across one of these bad boys, I did the pin testing extensively before hooking it up to anything and determined it takes standard Corsair type 4 cables. Even if other cables like evga or seasonic fit in the hole, the pin out is wrong. But so far...

Put the passive mcio card in slot 1 closest to the CPU and i bet it will work fine with a good mcio cable or two. Are you reconfiguring it custom, or leaving all the mcio mappings default x16x16x16x16x16x16x4?

Good luck, let us know your progress. And yes, the ADA card is attached to a virtual machine running the ngreedia DGX OS 7 (which is actually ubuntu 24 with about 1100 packages installed lol) its doing mostly text to speech work right now, narrating my browser's content to me because my old...

I attached a screenshot, The 7R13 is an Amazon AWS chip with 48 cores boosting to 3.8ghz with a 280w tdp. The arctic SP3 heatsink on it is amazing and very quiet. I do run desktop VMs that can use GPUs on it, but not gaming. Spinning rust drives are against my religion, everything I have is SSD...

Those AM5 chips with only 8 cores on a single compute die do sip power. The 10gig realtek nic on the asus b850 board works great btw, easily capable of linerate CIFS if you set up SMB properly for multichannel etc. Edit: I just pulled my power monitor for the epyc board with 48 cores, 8 sticks...

If you are trying to build a nearly silent system for your bedside table, the only fan options in the supermicro are somewhere between leafblower and tornado. Its designed for server rooms and refuses to let you inhibit that nature. For a while I completely bypassed the fan headers on the...
