it is quad channel

DIMM# are symmetrically assigned, like mirror image

DIMM1 white

manual may have an error in notation

"chassis" 1, 2, 3, 4 should be "channel" 1, 2, 3, 4

1st column is total memory installed

DIMM convention:

white slot is slot 1 of a memory channel.

DIMM1 white: slot 1 of ch0

DIMM2 white: slot 1 of ch1

DIMM3 white: slot 1 of ch2

DIMM4 white: slot 1 of ch3

redxps630 · Answer

DIMM convention:  black slot is slot 2 of a memory channel DIMM5 black: slot 2 of ch0 DIMM6 black: slot 2 of ch1 DIMM7 black: slot 2 of ch2 DIMM8 black: slot 2 of ch3

joe blo · Answer

no.. what im looking for (and the manual should have done it this way) is,  channel 0, sub 0 = DIMM #__ channel 0, sub 1 = DIMM #__ etc.. DIMM #'s on the chart.. this would be totally clear

In the Precision 5810, support memory configurations can be installed as follow:

1 stick of RAM, install to DIMM1

2 sticks of RAM, install to DIMM1 + DIMM2

4 sticks of RAM, install to DIMM1 + DIMM2 + DIMM3 + DIMM4

8 sticks of RAM, install to all DIMM slots.

System will support these sticks of RDIMM RAM: 4GB, 8GB, 16GB, and 32GB.

DIMM slot numbering is imprinted on motherboard and electrical overview label on side panel.

For some working unsupported memory configurations, install the extra stick(s) to the next numbering DIMM slot

Sachmalh · Answer

So say I have 3 of 8gb sticks and like 8 of 4 gb, can i use the 8gb sticks like even 2 or is that a bad idea

derickson2402 · Answer

One of my ram slots is damaged. While particular about balance, the 5810 will allow for a channel to go unused, as well as with mixed capacities.

Known working config is such:

Slot # —> Channel.slot—> Chip
DIMM1 --> ch0.0—> 4g
DIMM2 —> ch1.0 —> 4g
DIMM3 —> ch2.0 —> EMPTY
DIMM4 —> ch3.0 —> 8g
DIMM5 —> ch0.1 —> 4g
DIMM6 —> ch1.1 —> 4g
DIMM7 —> ch2.1 —> EMPTY
DIMM8 —> ch3.1 —> 8g

With proper balance, 4g and 16g sticks can mix. I did not record the configuration that worked for me, but I believe 2x4g sticks in one channel and 1x16g in another, with a third wholly unpopulated channel. Also, balance across both sides of the CPU (odd vs even DIMMs) seemed to work best.
