From modest host to mad scientist build \u2014 Hammer is now running an i9 with 128GB RAM<\/p><\/blockquote>\n

On July 20, 2025, I published this article titled \u2018Servers<\/a>\u2019, where I walk through the home servers we\u2019ve assembled over the years.<\/p>\n

In that article, I wrote that the ultimate upgrade for my Proxmox host would be an i9\u20119900T and 128 GB of memory, though I was still unsure whether I\u2019d actually do it.<\/p>\n

Well\u2026 OOPS \u2014 I DID IT!<\/p>\n

The upgrade<\/h2>\n

I decided to upgrade three integral parts of my Proxmox host:<\/p>\n

    \n
  • Memory<\/strong>: From 64 GB to 128 GB<\/strong>!<\/li>\n
  • CPU<\/strong>: From i7 9700T to an i9 9900T<\/strong><\/li>\n
  • Powersupply<\/strong>: From Pico PSU 80 to a PicoPSU 160XT.<\/li>\n<\/ul>\n

    Memory<\/h3>\n

    I think this is stating the obvious. It\u2019s a hypervisor. It eats RAM for breakfast. 128\u202fGB? Yes please!<\/p>\n

    CPU<\/h3>\n

    More cores, more threads \u2014 more breathing room. The system can spread the load effortlessly across everything.<\/p>\n

    PSU<\/h3>\n

    This one\u2019s a bit less obvious. The i9\u20119900T is slightly more power-hungry than the G5400, the i3\u20118300T, or the i7\u20119700T that came before it \u2014 that\u2019s reason number one.<\/p>\n

    The other reason is more subtle. The current PicoPSU has been running non-stop for over five years. Five years of constant (ab)use, voltage spikes, a few power cuts\u2026 by now, it\u2019s basically battle-hardened.<\/p>\n

    Think of it like a clutch plate in a car: if you\u2019re already doing open-heart surgery on the system, you might as well replace one of its most crucial components \u2014 the PSU.<\/p>\n

    Ebay ( CPU and memory )<\/h2>\n

    Finding the parts on eBay was the easy part. The delivery, however, turned into a logistics nightmare.<\/p>\n

    I ordered everything on July 26th. It took over a month \u2014 until the end of August \u2014 for the CPU and memory to finally arrive.<\/p>\n

    PicoPSU<\/h2>\n

    The PicoPSU was a minor nightmare as well.<\/p>\n

    Sure, there are plenty of websites that sell the PicoPSU 160XT \u2014 but almost all of them sell the PSU and the power brick separately<\/strong>, and here\u2019s the catch: the PicoPSU comes in two versions \u2014 one with a 4-pin connector, and one with a single-barrel input.<\/p>\n

    See the problem? You order the PSU from one place and the power brick from another\u2026
    (or even from the same webshop, as a matter of fact)<\/em> \u2014 and end up with a barrel-style PSU and a 4-pin-only power brick. YAY.<\/p>\n

    Eventually, I found a shop in Germany that sold a matching set. I ordered it there \u2014 and three days later, the package arrived. No mismatches this time.<\/p>\n

    Upgrade time!<\/h2>\n

    Okay. Me being me, I prepared everything to the tee.<\/p>\n

    \u2705 Software updates? Check.
    \u2705 BIOS update available? Check.
    \u2705 All components neatly laid out on the table? Check.<\/p>\n

    Tools?<\/p>\n

    Check.<\/p>\n

    Glasses (yeah, I need those)?<\/p>\n

    Check.<\/p>\n

    Extra lighting?<\/p>\n

    Check.<\/p>\n

    Let\u2019s do this.<\/p>\n

    Bios upgrade<\/h3>\n

    \"\"<\/p>\n

    BIOS version: R1.6.0<\/strong>, while the latest available version is R1.29.0<\/strong>.<\/p>\n

    Oh \u2014 and a nice little warning about the CMOS battery too.<\/p>\n

    Yep\u2026 that\u2019s what happens when your system is headless and tucked away in a hard-to-reach spot.<\/p>\n

    And that BIOS update? Absolutely mandatory.<\/p>\n

    It included microcode updates for the stepping of the new CPU, added support for 128\u202fGB of memory, several stability fixes \u2014 and, of course, a boatload of CVE patches.<\/p>\n

    BIOS update? Done.<\/p>\n

    \"\"<\/p>\n

    No drama. No errors. Just\u2026 done.<\/p>\n

    (That never happens.) \ud83d\ude1b<\/em><\/p>\n

    CPU Time<\/h3>\n

    Remove the cooler.<\/p>\n

    Clean the cooler.<\/p>\n

    Clean the old CPU.<\/p>\n

    Remove it.
    Insert the new one.<\/p>\n

    Reapply thermal paste.<\/p>\n

    Reseat the cooler.<\/p>\n

    Everything in reverse order \u2014 like clockwork.<\/p>\n

    And then\u2026<\/p>\n

    Boot time.<\/p>\n

    Does it POST?<\/strong><\/p>\n

    Well \u2014 I already gave it away, didn\u2019t I?<\/p>\n

    \"\"<\/p>\n

    16 logical CPUs detected!<\/strong><\/p>\n

    \u2705 The i9\u20119900T is fully recognized. We\u2019re in business.<\/p>\n

    Memory time!<\/h3>\n

    Next up: the RAM.<\/p>\n

    Okay \u2014 I\u2019ll admit it. This was the first time during the whole upgrade where I actually got a bit nervous.<\/p>\n

    Removing the old memory? Easy. Installing the new 4\u00d732\u202fGB modules? Also easy.<\/p>\n

    Then came the moment of truth: powering up the system.<\/p>\n

    And then…<\/p>\n

    Nothing.<\/strong><\/p>\n

    No POST.<\/p>\n

    So I pulled out 2\u00d732\u202fGB. Tried to restart the system \u2014 and lo and behold\u2026<\/p>\n

    POST!<\/strong><\/p>\n

    I added the other 2\u00d732\u202fGB again\u2026<\/p>\n

    The machine booted up just fine.<\/p>\n

    Maybe I didn\u2019t seat one of the DIMMs properly the first time?<\/p>\n

    Wouldn\u2019t be the first time.<\/p>\n

    \"\"<\/p>\n

    Memtest is running.<\/p>\n

    And running.<\/p>\n

    And running.<\/p>\n

    And yes \u2014 this will take ages. But I\u2019m not reinstating the system without a proper memory test.<\/p>\n

    As I\u2019m writing this, Memtest has been running for 1 hour and 50 minutes.<\/p>\n

    It\u2019s 68% through the test \u2014 and so far, not a single error.<\/p>\n

    It took almost three hours to complete.<\/p>\n

    The verdict: P A S S!<\/strong><\/p>\n

    YES!<\/strong><\/p>\n

    Three hours well spent!<\/p>\n

    Settings<\/h2>\n

    While checking the BIOS, I found a few more settings I could tweak.<\/p>\n

    And immediately, I noticed a huge difference when running powertop<\/em>.<\/p>\n

    I\u2019ve never seen this before \u2014 very interesting!<\/p>\n

    \"\"<\/p>\n

    Proxmox<\/h2>\n

    \"\"<\/p>\n

    Proxmox booted up without issues.<\/p>\n

    All VMs are starting as expected.<\/p>\n

    Both the CPU and the full 128 GB of memory are detected properly.<\/p>\n

    Consumption<\/h2>\n

    The system is still in its initial startup phase.<\/p>\n

    Right now, power draw is at 22.7 W<\/strong> \u2014 decent, but nowhere near the 10\u201312 W idle<\/strong> I used to see before this major surgery.<\/p>\n

    I also have to keep in mind that the larger power brick combined with the PicoPSU 160XT might introduce a slightly higher idle draw.<\/p>\n

    And if that\u2019s the case \u2014 is it significant enough to justify switching back to a PicoPSU 80?<\/p>\n

    And more importantly: is that even possible?<\/em> Can the smaller PSU deliver enough power for this beast of a setup?<\/p>\n

    And while I\u2019m writing this, I\u2019m finally seeing values drop below 20 W<\/strong> for the first time.<\/p>\n
