How to fix UEFI Error HWC8010 or HWC8011 on Dell server r750xs POST

 Fixing UEFI Error HWC8010 or HWC8011 on a Dell PowerEdge R750xs during POST typically involves troubleshooting hardware compatibility, firmware settings, or memory/storage issues. Since this is a server-grade system, the steps may differ slightly from consumer PCs. Below is a structured approach to diagnose and resolve the issue.

How to fix UEFI Error HWC8010 or HWC8011 on Dell server r750xs POST


Possible Causes for HWC8010/HWC8011 on Dell R750xs:

  1. Incompatible or Faulty RAM

  2. Incorrect UEFI Boot Settings

  3. Outdated or Corrupted BIOS/UEFI Firmware

  4. Storage Drive Compatibility Issue (NVMe/SATA)

  5. Secure Boot or TPM Configuration Conflict

Step-by-Step Fixes:

1. Reset BIOS/UEFI to Defaults

  • Restart the system and enter UEFI/BIOS Setup (usually by pressing F2, F12, DEL, or ESC during boot).

  • Look for an option like "Load Defaults" or "Reset to Factory Settings".

  • Save changes and reboot.

2. Check & Reseat RAM

  • Power off the system and unplug it.

  • Remove RAM sticks and reseat them firmly.

  • Test with one stick at a time to identify faulty RAM.

  • Ensure RAM is compatible with your motherboard (check manufacturer specs).

3. Update BIOS/UEFI Firmware

  • Visit the motherboard/Dell support site and download the latest BIOS.

  • Follow instructions to update (usually via a USB flash drive in BIOS or using a built-in updater).

4. Adjust UEFI Boot Settings

  • Enter BIOS and check:

    • Boot Mode: Set to UEFI (not Legacy/CSM).

    • Secure Boot: Try disabling it temporarily.

    • Fast Boot: Disable if enabled.

5. Check Storage Drives

  • If using NVMe SSD, ensure it’s properly seated.

  • Try booting with only one drive connected.

  • If the drive is new, check if it requires a UEFI driver (some older systems need NVMe support updates).

6. Disable TPM or Clear TPM (if applicable)

  • In BIOS, look for TPM (Trusted Platform Module) settings.

  • Try disabling TPM or clearing its keys (if error persists).

7. Test with Minimal Hardware

  • Disconnect all non-essential devices (extra drives, GPUs, USB devices).

  • Boot with only CPU, 1 RAM stick, and boot drive.

8. Check for Dell-Specific Fixes (if applicable)

  • Some Dell systems may need a BIOS recovery (check Dell’s support site for HWC8010/HWC8011 errors).

  • Try Dell SupportAssist for automated diagnostics.

Final Steps if Error Persists

  • Test with a different PSU (if possible).

  • Reset CMOS (remove motherboard battery for 5 mins).

  • Contact Dell/Motherboard Support if the issue remains unresolved.

If the error appeared after a hardware change (e.g., new RAM or SSD), revert to the old configuration to confirm compatibility.

What Is a Database Server Used For?

  Database servers have several use cases. Some of them are: Dealing with large amounts of data regularly. Database servers shine in a client-server architecture, where the clients frequently process data. Managing the recovery and security of the DBMS. Database servers carry out the constraints specified within the DBMS (database management system). The server controls and manages all the clients connected to it and handles all database access and control requests. Providing concurrent access control. Database servers provide a multi-user environment where many users can access the database simultaneously while maintaining security and hiding the DBMS from the clients. Storing applications and non-database files. Some organizations use database servers as a much more efficient solution compared to file servers.   How Does a Database Server Work? The database server stores the Database Management System (DBMS) and the database itself. Its main role is to receive requests from...
