January 14, 20206 yr Hi! I have posted about this before, but I did not get an answer and I have found some more information. I have a Huananzhi x79 8D motherboard with 8x8GB of DDR3 ECC memory and 2 x Xeon E5 2670 CPU:s. The unraid dashboard lists my RAM to be 32GB (instead of 64GB). The system information as well: Model: Custom M/B: HUANANZHI X79-8D Version VAA31 - s/n: MB-201903272019 BIOS: American Megatrends Inc. Version 4.6.5.

January 16, 20206 yr Hi there, I've passed this along to the devs to take a look. I'm guessing that this is only an appearance issue and that nothing functionally is broken (e.g. you can still assign more than 32GB of RAM to VMs and whatnot). Please confirm.
January 16, 20206 yr I've gone ahead and copied this into our bug reports forum for stable releases. I've listed it under the category of "annoyance" as it doesn't seem to affect functionality, but obviously isn't reporting the correct data. Further commenting on this should be done over there:
January 17, 20206 yr Author OK, thank you. It seems like it would be easy to fix, related to how Unraid processes the system information?
January 17, 20206 yr Unraid relies on the information given by the BIOS of your motherboard. Check if there is any newer BIOS available.
January 18, 20206 yr Author Hi! I have done some more digging. The problem seems to be with dmidecode, the command that the unraid GUI uses to fetch system information. When I run dmidecode manually I get some output and in the end the following error: Invalid entry length (0). DMI table is broken! Stop Is there a way to fix the DMI table? Only through BIOS update? Thank you! /Erik
June 26, 20215 yr I apologise for the thread necro, however I was having the same issue that eribob experienced but with only 64-GiB of DDR3 ECC showing instead of 128GiB. With the lead from eribob's digging, I found the exact same problem with dmidecode and discovered there is a typo in the DMI Table (Instead of 0x17 (23 bytes) length being used, it was 0x23). After a bit of researching and work, I've now modded my bios (no updates from Huananzhi were found) to fix this. Unraid 6.9.2 now shows all RAM now. I have a rough guide for others who experienced this (from my research, it looks like it's any chinese dual socket 'x79' board is affected), to fix it as well here: https://www.win-raid.com/t9047f16-Request-for-help-fixing-DMI-Tables-on-a-Huananzhi-X-D.html I also apologise if the link breaks any rules, I don't see anything that prevents it, but I might have missed something.
June 28, 20215 yr Author Wow this is awsome! Great work crenn! I had lost all hope of solving this problem… I have upgraded my system and sold the huananzhi board already but I will save this post in case I decide to build a second system in the future. /Erik
November 28, 20223 yr after the last update (unraid 6.11.4/5 my processor Information and ram Information cannot be retrieved with dmidecode

Hey friend, the link is broken, do u have another valid link?
January 4, 20251 yr I recently upgraded my unRAID from version 6.12 to 7.0.0rc2 and am now encountering this issue. System info shows: Memory: 0 GiB Multi-bit ECC Did not see this issue when using 6.12. Does anyone know if this will be resolved in future software updates?
