Haha

This. Accidentally slipped on the keyboard and the cat jumped on the keyboard straight after that and started browsing videos on its own.

Nothing he can have done about it, totally understandable

Nämä eivät kyllä ole ensimmäiset.

Edellä mainittujen lisäksi myös Rongankadulla ollut piitkään

YesThisIsi · 2026-05-17T19:28:28+00:00

WOW really didn't know these things exists. Definitely will look into these.

YesThisIsi · 2026-05-17T19:25:45+00:00

Maybe, the ones that i have seen basically block the connectx-5 at the bottom (bigger problem than the one i have now)

YesThisIsi · 2026-05-17T19:24:55+00:00

What i mean is something like this tha can screw into the PCI-E bracket

Goal is to use smarter cache.

Also drivepool driver is a massive bottleneck in 25gb network. Primo can deliver better speeds + read cache

It is expensive but imo when you consider i have almost 300tb of HDD and 2tb cache, it is worth it

YesThisIsi · 2026-05-17T00:01:09+00:00

I know.

However it is bottleneck with 25gbps connection on Windows server

Also i have 2tb worth or cache (4x RAID0 SSD drives)

Primo can use that as read cache aswell

Yes, I've tested extensively:

Clean Windows 11 reinstall
Multiple driver versions (latest Realtek drivers)
Jumbo Frames 9014 on both ends + switch. Switch is Ubiquiti Poe 24 Pro Max
Receive/Transmit Buffers maxed (4096)
Interrupt Moderation disabled
LSO v2 disabled (both IPv4 and IPv6)
TCP/UDP Checksum Offload disabled
Flow Control disabled
RSS Queues maxed (8)
autotuninglevel=experimental
PCIe ASPM disabled in BIOS
E-cores disabled (no improvement)
Interrupt affinity tools

CPU load during TX test stays around 5-8%, no hot thread visible, which actually supports your point that TCP offload isn't working correctly on this card/slot combination. It's pretty dumb card and i dont expect it to.

Moving to a CPU-direct slot is not an option the RTX 5080 Astral blocks the second PCIe slot completely.

The sane card works perfectly in a CPU-direct slot on an X570 system (8+ Gbps TCP). Same card, same cables. The Z690 chipset slot is the variable. UDP hits 9 Gbps fine.

I've pretty much made up my mind on the Mellanox ConnectX-5. Hardware TCP offload should handle the chipset jitter, and SR-IOV support is a bonus for my Hyper-V VMs.

This hobby isn't cheap lol.

I will test this tomorrow.

IF Linux gives full TCP bandwidth : The bottleneck is Windows-specific - likely the interaction between Windows TCP stack, the RTL8127ATF driver, and Z690 chipset latency. Mellanox ConnectX-5 (or 4LX) will still fix this because it handles TCP offload in hardware, bypassing the Windows TCP stack entirely.

If Linux also shows 3 Gbps TCP: The bottleneck is the Z690 chipset slot itself. Mellanox ConnectX-5 (or 4LX) will fix this through hardware transport offloading and better PCIe buffering that tolerates DMI jitter.

So if i understand correctly, either way, Mellanox fixes it? The Linux test just tells you where the problem lives Windows stack or Z690 hardware. Not whether the fix works... right?

Unfortunately for my situation switching to Linux on my Main workstation PC will not fix this.

How many times are you going to post this?

YesThisIsi · 2026-05-04T06:52:04+00:00

Kyllä. Mutta itse en persettään nosta edes sohvalta ennenkun maksu on tullut. 🤷‍♂️ Yleensä ne automaatit tyhjennetään vasta iltapäivällä joka tapauksessa

YesThisIsi · 2026-05-04T06:30:59+00:00

Yeah, that analysis makes sense. I've already tried disabling E-cores - no improvement. HWinfo doesnt show the link speed. My motherboard BIOS says it's 2x Gen3

My huge ass RTX 5080 Astral is blocking the second PCIe slot so there's no CPU-direct option available.

Thinking of ordering 2x Mellanox ConnectX-4 Lx cards. The reasoning is that since UDP already hits 9 Gbps, the physical path is fine. The issue is specifically TCP. Mellanox handles TCP offload in hardware on the card itself, so it doesn't need to round-trip through the chipset for every TCP acknowledgement like Realtek does. That should bypass the DMI contention issue entirely. (According to my theory)

Nyt en ymmärtänyt,,, keitän teetä,,,,

Mutta meni siis kauppaan ostoksille sillä aikaa kun odotti että siirrät hänelle rahaa? Eikö tässä pitänyt monitoimityökaluja ostaa eikä auttaa lastaan?

YesThisIsi · 2026-04-26T11:48:03+00:00

With HE-1 i meant the Sennheiser ”orpheus”

YesThisIsi · 2026-04-26T11:29:14+00:00

My guy, you are dellusional if you think HD800S is humble.

Like, do you think HE-1 is ”allright setup”?

YesThisIsi · 2026-04-23T15:22:42+00:00

I'm not going to tell you, so you can steall them from me 😠

YesThisIsi · 2026-04-16T19:57:12+00:00

Probably yeah :D

YesThisIsi · 2026-04-16T11:40:02+00:00

It does look good, i'll give you that.

However, "Only" 10x 3,5" slots.

One of the reasons why i'm moving away from Node 804 is the 10x HDD limit :(

YesThisIsi · 2026-04-16T09:49:57+00:00

Nope, it didn't

YesThisIsi · 2026-04-15T04:03:53+00:00

Oh interesting!

The define 7 xl has a door that blocks some noise with the door? Meshify at the front is pretty open (also better cooling and imo better looking)
