Dedicated server RAM throttled

  Hi all, MEVSPACE here again I am posting from the official account, as my personal account was banned.

  This is not artificial throttling done by MEVSPACE. On AMD AM5 platforms, the supported memory speed depends on how many DIMM slots are populated.

  For example, according to AMD’s official specification for the Ryzen 9 9950X:

  https://www.amd.com/en/products/processors/desktops/ryzen/9000-series/amd-ryzen-9-9950x.html

  Max Memory Speed:

  • 2x1R: DDR5-5600
  • 2x2R: DDR5-5600
  • 4x1R: DDR5-3600
  • 4x2R: DDR5-3600

  So when a server is configured with 192 GB or 256 GB RAM, we need to populate all 4 memory slots using 48 GB or 64 GB modules. In that case, the memory bus speed is reduced to DDR5-3600 according to AMD’s specification.

  If you want to achieve the higher memory speed, you should order a 96 GB or 128 GB RAM configuration. In that case we can use only 2 memory slots, which allows the platform to run at the higher supported memory speed.

  Regarding the reported case where a 96 GB RAM configuration was running at 3600 MHz: I have not checked this specific server yet, but I assume this may have been our mistake and the wrong memory slots may have been populated. We will add an additional check to our automation tests to verify correct DIMM population for such configurations.

  Regarding the BIOS password: yes, BIOS access is restricted on our servers. This is not because we do not want to give customers control, but because we have seen a high number of hardware failures caused by overclocking or unsafe BIOS changes made by customers.

  We are currently working with ASUS on a special BIOS version for our servers. Our goal is to allow customers to change selected safe settings while keeping overclocking and other risky options disabled. Once this BIOS is ready and tested, we plan to gradually roll it out to our machines.

  MEVSPACE is open to customer needs. If you have any special requirements, please contact us and we will always try to help where possible.

  Do you support full fan speed?

  This is what makes a provider a good provider! Not just acknowledging and remedying the problem, but taking steps to ensure no problems of that kind are capable of happening in the future. Respect!

  Could you elaborate on what you mean by “full fan speed”?

  In IPMI its possible to make the server fans spin at full speed, this helps in avoiding throttling and achieves cooler hardware

  I think you are mixing 2 different, unrelated things IPMI is just a remote console to the
  server. Fans settings are in BIOS, in case of OP - behind a password.
  Onlyfans settings are open, depends on your preferences

  Well speaking about supermicro here, of course available in bios as well

  All our Ryzen 9 servers, including 5950X, 7950X and 9950X, are water-cooled. There is no direct CPU fan installed on the CPU heatsink. Cooling is handled by the water-cooling loop, with a pump and radiator fan.
  So in this case, “CPU fan speed” is not applicable in the traditional sense, because these servers do not use a standard air cooler mounted directly on the CPU.

  Pump RPMs and pressure then?

  I think we need a video tour of the water cooling setup to prove it's real.

  Hey @Mevspace, so is 5200 the max for 2 DIMM you will do even though the RAM is 5600? Not a big issue if so, just curious since that's the solution I was provided.

  Good to hear you're working on making these things doable by the customer themselves, though I have to say the response times from support have been very good and impressive.

  If not already in the works, one improvement you can make in the future is the firewall page in the dashboard, it's a little too basic compared to the options in hetzner for example (it's fine currently but can be improved).
