First, try removing the CMOS battery for a few minutes to reset the BIOS to its default settings. Ensure that all necessary connections are secure and check the status LEDs on the mainboard to determine if the server is ready to boot. If the issue persists, further hardware diagnostics may be needed. [community thread]
A detailed list of supported processors for the R640 can be found in the technical guide provided by Dell. If you have questions about specific processors not listed, consider reaching out to customer support for assistance. [community thread]
This is a known presentation error in iDRAC9 where the CPU speed is incorrectly labeled as MT/s instead of MHz or GHz. It does not indicate a hardware or firmware issue, but rather a unit-labeling mistake in the user interface. [community thread]
The issue may arise from differences in memory rank, firmware, or PCB revisions between the original and new DIMMs, even if the part numbers match. To troubleshoot, try booting with one module from each set in different CPU slots, and consider updating the BIOS and iDRAC firmware. If problems persist, you may need to return the new modules for ones that match the original revision. [community thread]
If you encounter a memory error after changing CPUs, first ensure that the memory modules are correctly seated and populated in the appropriate slots. Check for any bent pins on the CPU socket, as this could indicate a problem. If issues persist, consider isolating the components to determine if the memory or CPU is faulty. [community thread]
