PowerEdge R710 Upgrading RAM by adding 2 8GB sticks

Jump to solution

I have a dual processor PowerEdge R710 that current has 8 sticks of dual rank 2GB UDIMMS. I am attempting to upgrade the server to 32GB and ordered 2 matching 8GB dual ranked UDIMMS.

Called Dell and well they are unsure does anyone know what would be the correct placement to get this all to work in Optimized mode?

Original Configuration - 16GB Optimized Mode

A1 =  A4 =  A7 =  A2 = 2GB A5 = 2GB A8 =  A3 = 2GB A6 = 2GB A9 = 
B1 =  B4 B7 =  B2 = 2GB B5 = 2GB B8 =  B3 = 2GB B6 = 2GB B9 = 

Current Configuration - 28GB Advanced ECC Mode, Replaced the 2GB sticks in A2 and B2 with the 8GB sticks and getting boot error  as described but all works other wise.

A1 =  A4 =  A7 =  A2 = 8GB A5 = 2GB A8 =  A3 = 2GB A6 = 2GB A9 = 
B1 =  B4 B7 =  B2 = 8GB B5 = 2GB B8 =  B3 = 2GB B6 = 2GB B9 =

Four 4GB sticks and 4 2GB sticks would give you a configuration that won’t give an error. We never shipped UDIMMs greater than 2GB, but it probably, as you have found, works fine, it just isn’t validated. The recommended way to get to 32GB is to buy four 8GB RDIMMS and replace all of the existing memory.

Hi,

The memory channels don’t match, so you are going to get an error, A2,A5 and A3,A6 and the same on the B side are the channels, the 2,5 channels have 10GB total memory and the 3,6 channels have only 4GB.

ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r710_Owner%27...

Page 129

Memory modules of different sizes can be mixed within a memory channel

(for example, 2-GB, 8-GB, and 4-GB), but all populated channels must

have identical configurations.

Hi Josh,

Thank you for your response.

So from this no matter the mode/configuration I will get an error.

To even this out and get it working I would need to return both of the 8GB sticks and buy 4 sticks of 4GB, so that I could get this system to 32GB with the below configuration.

*note i would mirror this on the "B" side.

A1 =  A4 =  A7 = 
A2 = 4gb A5 = 2gb A8 = 2gb
A3 = 4gb A6 = 2gb A9 = 2gb

Also I see this document states -  1-GB and 2-GB UDIMMs are supported for a total of up to 24 GB.

is this correct? so I should max out at 24, where right now I cna get 28. Can I get 32gb with UDIMMS?

Hi Josh,

I am looking at going your recommended route and just want to cross all the t's before I dedicate myself this direction.

4 sticks of  - 3D Memory 8GB Module DDR3 PC3-10600 CL=9 Registered ECC w/Parity DDR3-1333 Dual Rank, x4 1.5V 1024Meg x 72 for Dell PowerEdge R710 Mfr P/N A2626092; SNPM015FC/8G

With a stick in A1 and A4 and then mirrored on the B side in B1 and B4, in optimizer mode.

RE: PowerEdge R710 Upgrading RAM by adding 2 8GB sticks

Jump to solution

Hello,

I have 18 memory modules (8GB PCL3-10600R 2Rx4) to install on the Dell R710.
Configured system with 2 processor sockets.
When installing the modules, the memory frequency is reduced to 800Mhz.
My questions are:
How much memory can I put into the system using 8Gb modules without reducing system speed and performance?
What slots should I use?
Should I set up optimized or advanced Ecc?

Sorry my english, I'm using translator.
