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]
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]
This issue may arise from a compatibility problem between the SSDs and the RAID controller, particularly during reboot sequences. To troubleshoot, ensure that both the PERC H730P Mini and the SSDs have the latest firmware updates, and verify if the SSDs are officially supported by Dell. Additionally, consider adjusting BIOS settings, checking power connections, or testing different RAID configurations. [community thread]
To turn off the default fan speed response for a third-party PCI card, use the command 'racadm set system.thermalsettings.ThirdPartyPCIFanResponse 0'. If you encounter an 'Invalid object specified' error, ensure that your iDRAC firmware is up to date and that you are using the correct command syntax. [community thread]
The 64GB 2RX4 DDR4 RDIMM 3200 MT/s is not compatible with the Poweredge R640 when using Skylake CPUs. Please verify compatibility with your specific server configuration before purchasing. [community thread]
Both the R440 and R640 servers can support up to x8 U.2 NVMe SSDs with the appropriate storage controller. Ensure that your Micron 9200 MAX drives are U.2 NVMe models, as they are compatible for use in both servers. [community thread]
You can use any compatible motherboard for the Poweredge R640, but it's advisable to stick with the same version or a newer revision to ensure full feature support. The PCIe layout should remain consistent across all motherboards for this model. [community thread]
The R640 and R640 XL are similar in many respects, but the R640 may have access to firmware updates that the OEM version does not. For more specific details, consult the documentation provided by the manufacturer. [community thread]
