Dell R710 RAM
Hi All,
I have a Dell R710 server. I have populated all 18 slots with 4Gb RAM modules. The BIOS is showing 72GB if RAM at 800Mhz.
During Boot I get the following Error/Warning
Unsupported memory config. DIMM mismatch across slots detected.
The following DIMMS should match in geometry DIMM A4, A5, A6
The following DIMMS should match in geometry DIMM B4, B5, B6
I'm not sure why I am getting the error.
I have read this:
Taken from here: ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r710_User's%20Guide7_en-us.pdf
The memory speed of each channel depends on the memory configuration:
• For single or dual-rank memory modules:
– One and two memory modules per channel support up to 1333 MHz.
– Three memory modules per channel support up to 800 MHz.
• For quad-rank memory modules:
– One memory module per channel supports up to 1067 MHz.
– Two memory modules per channel are limited to 800 MHz, regardless of
memory module speed.
is this error because I am using 3 modules per channel and the speed has dropped to 800Mhz.
The bios is also running in optimizer mode and I cant change this mode (it is fixed)
Thanks in advance.

Remove all memory and slowly insert 4GB DIMMs slowly making sure each is seated correctly
After adding each bank power on and test

There are 3 different types of modules
4GB 2Rx8 PC3 - 10600
KVR 1333 D3D8R9S/4GB
4GB 1Rx4 PC3
4GB 2Rx8 PC3 - 10600

I am able to populate A1-A8 and B1-B8 total RAM is 64GB at 10600Mhz
If I populate the final bank A9 & B9 I get the error above.
If I populate the final bank A9 & B9 I get the error above.
So RAM incompatible

I have opened a case with Dell, I will revert. I should be able to get away with just 64GB RAM.
