RAM Installation: Channel Patterns Based On Speed

Question

Hello guys, Newbie here. I own a refurbished Dell PowerEdge R710 and I cannot get the memory speed up to 1333MHz. The modules are running at this speed and I think that there is something with the installation pattern regarding to the manual:http://downloads.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r710_Owner%27s%20Manual_en-us.pdf I have 2 CPUs and now the two identical RAM modules use A1 and B1. In which slots should I install the ram modules in order to have speed 1333MHz and full functionality? Unless my installation is wrong, should there be a misconfiguration through bios/iDRAC? Thank you in advance.

Hi,    Thanks for the details.    Seems like the processor does not support 1333 speed, based on Intel's ARK details on the processor: https://dell.to/39Fk5na

Hi there,   Can I know your BIOS and BMC version, what processor are you using, and probably a picture of the memory specs that you are using.

Hello @DELL-Joey C,

Thank you for your reply. As I said noob here, it took me time to find BMC info. I assumed you mean iDRAC firmware so we have the following:

Bios Version: 6.4.0 (I think it's outdated, the last one must me 6.6.0)
CPUx2: Intel(R) Xeon(R) CPU E5630@2.53GHz, 4 cores, 8 threads
RAMx2: https://www.poweredbymushkin.com/Home/index.php/catalog/memory/proline/item/930-991980
BMC(iDRAC firmware): 2.90 (Build 04)

Best regards,

Hello @DELL-Joey C , That has totally slipped of my attention and of course, the outcome is based on CPU, not in RAM installation. Thank you for you support.   Best regards,
