    Supermicro 6028U-TRTP X10DRU-i Barebone $349

    I've always assumed that it is to physically support an end mounting bracket for Graphics Cards.

    Supermicro SC825 Rev 2?

    I believe that you are correct, that rev K is older than rev M. I've got a mixture of rev K and rev M 825/826/836/846 chassis. Interestingly, the Ultra chassis that I have (which are much newer that the "generic" storage chassis noted above) are a mix of rev A and Rev B, but these chassis only...

    Supermicro SC825 Rev 2?

    I've also run into this issue on older revs of SM chassis. I believe that historically the dual CPU versions of the X9 motherboards were the ones that required a "revision M" chassis to support the specific standoff that you identify. To get around the issue I've used appropriately sized M3...

    Supermicro 6028U-TRTP X10DRU-i Barebone $349

    The power cables from the motherboard to the backplane are 1x8pin to 2x4pin, providing 4x4pin to the backplane. Depending upon the backplane, all 4pin cables may not be required. There are only 3 power connectors on the SAS3 backplane in my chassis, the 4th was neatly cable tied out of the way...

    Supermicro 6028U-TRTP X10DRU-i Barebone $349

    Bending the small tab that interferes with the heatsink is the same method that I took. There are a number of Ultra risers, I presumed that this is a "generic" kit to fit the range of risers as there was a few other mounting items that I didn't need.

    Supermicro 6028U-TRTP X10DRU-i Barebone $349

    Absolutely... Modularity IMHO the #1 benefit for Supermicro systems are their modularity. The Ultra range are a little more ""targeted" to performance compared to the "mainstream" line, but they are still very configurable. Take a look at the details of the ultra series from the Supermicro...

    Canon EOS C70 Real-world Usage Notes

    Canon and Sony are releasing some awesome technology these days, they duke it out for the #1 spot and we the consumers are the overall winners :D I sympathize with the 20+ month journey to try and figure out what works best for you, and kudos if you've finally made it! Congrats on the C70, it...

    Supermicro 6028U-TRTP X10DRU-i Barebone $349

    It sure can, you need to populate CPU0, but you only get access to the "Ultra IO" pci-e slots and not the WIO pci-e slots. The Motherboard Manual gives the details in the block diagram on page 1-10. The Networking Ultra Riser Adapter Compatibility Matrix shows the various risers that are...

    Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

    FWIW, as I have both the non-POE and POE units handy, I just checked idle power using a Kill-A-Watt once units have booted up and "settled down". The ICX6450-24 idles at ~24W and the ICX6450-24P idles at ~34W, so roughly in line with what you have seen.

    STH Forums a New Look and How to Switch to Dark Theme

    If we're giving feedback, my inner grump says I'm not a fan of the page animation effect, nor of the "every color in the rainbow" accents, which IMHO completely distracts the eye in the "dark" page view.

    How to track down a noisy fan ??

    Good suggestions so far, I'll offer an alternative which may be tedious ... possibly power down the server completely so the BMC has to "register" any fans before power up. (Pretty sure this works for Supermicro boards, but I have used Intel boards in the past that require a one time...

    Quick sanity test - VM single thread CPU Perf

    Server 2016 running on a Supermicro X10SRL-F with E3-1650v3, 32GB PC4-2133. VM is Win8.1, assigned 8GB memory and 4vCPU. Passmark CPU Single Thread score is 2170. I do want to note that I am running with adjusted Powercfg settings in S2016 to overcome some Plex server responsiveness issues...

    Likely impact of damage - corner of SP CPU

    I'm familiar with typical FC-BGA substrate materials and associated fabrication processes. I have not cross sectioned a finished LGA-3647 package to verify construction, but it will likely be a 400~600µm core (which provides the base "rigidity" for the substrate) with 4~8 build up layers per...

    Supermicro X10SRH-CLN4F Cooler

    If installing in a 4U chassis, consider the Supermicro SNK-P0050AP4 .. comes with square and narrow ILM attachments. Can be found a little cheaper at Newegg I've never used the Noctua cooler, but it implements a larger 120mm fan so should run slower. The specs on that noctua cooler indicates...

    a little computer trivia: "boot"

    feb ‘83 for me on DEC PDP-11, which had a boot loader, but after a few months was introduced to the older PDP-8, which (if memory serves me) required manual “load accumulator” sequence to bootstrap. Seem to remember that the PDP-8 was also sporting core memory, and not a lot of it (maybe 16k ?)...

    Dual NVMe PCIe Card?

    I purchased a couple of the AOC-SLG3-2M2 from CDW (at the time the cheapest I could find). The p/n on the box was AOC-SLG3-2M2-O. The card is supplied with the short bracket attached but there is a tall bracket included in the box (but not called out on the checklist) The part number on the...

    Accessing SATA Power cable in SM 36 Bay?

    With the 36bay SC847 chassis that I have, the motherboard tray slides back (need to pull on the blue release pin at the front of the tray) to access the backside of the rear backplane, and in the base of that area there are 2 places to mount a 3.5" drive tray (MCP-220-84701-0N). I've mounted a...

    Cheapest Dual SFP+ Intel NIC...X520?
