Required parts to make an R6525 work

Hi, I was wondering if there was some secret to installing an OS on a R6525. What I have done I know is not supported and may have been crazy but I wanted to try and see but I have hit a block I cant get past.

First off I bought a R6525 motherboard, 800w Dell EMC PSU, and a Dell locked 7252 CPU and some 16GB sticks of DDR4, and a fan or two. The board came with the LOM and iDRAC card. I have been able to configure everything , boot the machine , run all the tests everything passes, complains about no hard drives. My plan was to mount an iSCSI drive and install to that.

My issue is that any installer, Linux or Windows does not run and just locks the system up. All Linux installers hang after they boot and you hit install it is stuck from there on out, Windows makes it to the language selection and it is hung there. If I attach a USB SSD with a pre-installed Linux it will come crash as soon as it loads the kernel.

I have enabled the serial console and I get a core dump when the pre installed OS attempts to start and some stuff about ROM BAR errors.

I have contacted the place where I got the board and they offered a few ideas but mainly said it was the 800W PSU and not the 1400W PSU which I find pretty odd to be that, I ordered a riser module for it just cause  and I did reach out to Dell support and they are at least entertaining helping which I thought was cool but it is such low priority it is a week back and forth.

I have tried every BIOS they have pretty much, it will boot Memtest+ and into end EFI shell and update BIOS from there but beyond that I cant get anything to work and I have ran out of ideas on trying things. 

When it does fail to boot I get an error.

A high-severity issue has occurred at the Power-On Self-Test (POST) phase which has resulted in the system BIOS to abruptly stop functioning.

I was attempting to make use of some of these Dell locked Eypc CPUs you can get but I got stopped right off sadly.

I have also tried different RAM and CPUs just to rule that out, I know this is a long post and thanks for reading.

Based on the information provided, it seems that you are facing issues while trying to install an operating system (OS) on a Dell PowerEdge R6525 server with non-standard components. Here are a few points to consider:

  1. The R6525 is designed to work with specific Dell-certified components, and using non-standard or third-party parts may cause compatibility issues and prevent the system from booting or installing an OS properly.12
  2. The error message "A high-severity issue has occurred at the Power-On Self-Test (POST) phase which has resulted in the system BIOS to abruptly stop functioning" indicates a hardware issue, likely due to incompatible components or incorrect BIOS settings.1
  3. The 800W power supply unit (PSU) may not be sufficient for the R6525, as Dell recommends using a 1400W PSU for this server model. An underpowered PSU can cause instability and prevent the system from booting correctly.3
  4. The locked Dell CPU you are using may not be compatible with the R6525 motherboard, leading to the ROM BAR errors and core dumps you are experiencing during boot.12
  5. Using non-Dell certified RAM modules can also cause compatibility issues and prevent the system from booting or installing an OS correctly.3

To resolve the issue, you may need to:

  1. Obtain and use Dell-certified components, including the recommended 1400W PSU, compatible CPUs, and RAM modules specifically designed for the R6525.3
  2. Ensure that all components are properly seated and connected, and that the BIOS settings are configured correctly for the installed hardware.
  3. Consider seeking professional assistance or contacting Dell support, as they may be able to provide more specific guidance or troubleshooting steps for your particular configuration.

While it is possible to build systems with non-standard components, server-grade hardware like the R6525 is often designed to work with specific, certified components to ensure compatibility and stability. Using non-certified parts can lead to various issues, as you have experienced.123

@Dell-Martin S​ 

Well thanks for the information, I am going to guess it may be CPU related since that one is not on the list , which I went with the lowest cost CPU just incase I wasted my time overall.

I see that the 7262 is on the list so I feel that may be my best attempt and makes the most sense at the moment, I ,made an incorrect assumption that a Dell locked CPU would work but I may have been wrong.

I checked power draw it was no where near the 800w, though those fans are about insane.

Everything is dell except the memory , which did pass the Memtest+ test so maybe it is OK for this application.

 

I do realize what I am going is quite unsupported so I appreciate all the help I have gotten.

Well for what is it is worth a supported CPU did not fix the issue. It is looking like this may be a waste of time , and money now to have attemped.
