    Supermicro X9/X10/X11 Fan Speed Control

    FWIW I recall only being able to change the lowers. Well, those were also the only ones I was worried about. Also Noctuas as I recall. See my post #140 in this thread: https://forums.servethehome.com/index.php?threads/supermicro-x9-x10-x11-fan-speed-control.10059/post-339648

    Intel 15.36TB U.2 NVMe SSDs for $895 OBO New

    That’s some ultra low endurance. About 0.2 DWPD? You can get the D7-P5520 for about 50% more than that with 5X the endurance and much, much better performance if you’re doing more than reading. Using the 5520 in my Veeam B&R server and I have found it to be a great value.

    I have only used VROC with Server 2019 and on a different chipset, but here's what I know: 1) The BIOS has a firmware level driver - this is how you can interact with the VROC settings in the BIOS. In the Supermicro board I use VROC on, it allows configuring an array, etc. in the BIOS. Though I...

    Avago 9305-16e for $133 + ship in CDW Outlet

    Thanks for posting this @Samir. Have an existing business account w/ CDW so grabbed one and it arrived just like it should have.

    Supermicro X12STH Intel RAID limits

    If this is VROC, then it does support > 4 drives in RAID 5, but only RAID 5 (as I recall anyway). And there are increasing caveats for using it in Raid 5 with > 4 drives (delayed parity checks). If it's not VROC, then I have no idea ;).

    LGA 1700 Alder Lake "Servers"

    Yeah the P44 is pretty sweet. Windows is the limitation for me - do not recommend the various flavors of windows software RAID. But if you are on the *nix side I say go for it.

    LGA 1700 Alder Lake "Servers"

    I use RAID 1 for boot devices on all of my production servers at work, but don’t bother at home.

    LGA 1700 Alder Lake "Servers"

    As others have noted, IPMI value all depends on your environment. For me, it pays for itself after 1-2 unscheduled uses. I’ll need to check my notes for idle power. I think it was around 50-60W. 2 NVMe, 4 system fans and AIO pump. No add in cards and 2x32 GB.

    LGA 1700 Alder Lake "Servers"

    To answer the question on what folks are running: I have 2 of the SM boards, one 12900K, one 13900K. Had some issues getting Windows 11 to be happy on the 13900k but it was really early in the CPU release. Both have E cores disabled and are number crunches for CFD simulation. Both watercooled...

    W790 Motherboard discussion thread

    Level1Techs has had a few videos on this platform in recent weeks. It confirms if you want decent all core performance, some level of overclocking is needed and you need to budget 400-500W (minimum) for CPU cooling. See their Falcon Northwest system review for a "factory OC" that seems...

    Intel VROC with Bifurcation Card, only detects one drive. But Windows sees all four.

    Sounds like only one of the 4 "ports" is in VMD mode. When not in VMD mode the NVMe drives just show up as regular NVMe drives. I have a different X12 system and all of the NVMe connectors I am using are on mainboard (not using retimer cards). So my experience may not apply, but I'll try: In my...

    W790 Motherboard discussion thread

    I am on mobile so I will keep this relatively short. This article in AEC magazine has some good in-depth performance and behavior numbers. As feared and expected the CPU frequency/scaling performance is pretty abysmal as more cores are engaged. Without overclocking and therefore watercooling...

    Unknown - waiting on some 3rd party reviews and hopefully core scaling (watts vs MHz vs temps) data. Lead times were a few weeks on at least some of these, so I suspect not many in the wild yet. I built out a potential rackmount BOM for an overclockable DIY and it came to $4600: Item desc $...

    I know most of us are in the "build" camp, but for work I always check OEM for a benchmark. Supermicro, Dell and HP have their workstation configurators live. Supermicro has a watercooling option, the others look like air only. SYS-551A-T | Full-Tower | SuperServer | Products | Supermicro HP...
