DPE2900 RAM Upgrade

Jump to solution

I see that the YM-158  motherboard has four banks of three RAM slots.

I currently have the first slot of all four banks filled with crucial CT51272af667 4GB RAM (total 16GM RAM).

I'd like to upgrade the RAM, and am curious to know if installing 4 more crucial CT51272af667 4GB RAM in the second slot of all four banks would be the best way to do this.

Any input would be much appreciated.

Wappleg8,

That is correct. The key to the population of the dimms is that the dimm channels you described must be identically matched. So if you have 4 4gb dimms in the white tabbed slots then you can place the new 4 in black tabbed slots just adjacent to the older dimms. 

Let me know if this helps answer your questions.

Thanks Chris,

You are correct - there are 4 individual 4GB dimms in the white slots.

The RAM upgrade will be secondary,  once I get the DPE2900 powered on.   I have 2 new power supplies on their way so this weekend I can at least see is this will power on.

Currently:

The PowerEdge 2900 has-   a YM-158 motherboard,    UCP-51 RAID controller,   16GB RAM (the Crucial dimms) with     8 Seagate ST373455SS 73GB hard drives.

Once I get it powered on  my plan is to:

1- replace the 73GB hard drives with 8 2TB Seagate Constellation ES ST32000644NS hard drives in a RAID 10,
2- use the SATA connections on the motherboard for the OS on a SSD hard drive.
 (I will have a disk image of the OS drive to restore from if the SSD drive ever fails)

You mentioned the dimms having to be  'matched'.     Can I purchase 4 dimms of the same type,   or would it be best to purchase 2 matched sets of the 4GB dimms?

Thanks again Chris,

~Bill
