Mixing different memory modules in DL 385 G7

[Server-Support]

Hi,

I'd like to know if I can reuse the spare memory module from HP Proliant Blade (BL 465c G7) server into the HP Proliant DL 385 G7 server (573087 -371) ?

Current Memory Module that is used on DL 385 G7:

DIMM Description: DIMM 2GB PC3-10600R 128Mx8 RoHS

Additional DIMM Description: HP 2GB 2Rx8 PC3-10600R-9 Kit

Spare Part Number: 595094-001

Spare Memory Module: 4 GB 1 Rx4 PC3 10600R

HP P/N: 591750-171

From this page: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02188036 it is listed there but not sure if I can mix the spare 4 GB module above into the existing running HP Proliant DL 385 G7.

So is that possible to mix the spare 4 GB into the empty RAM slots while the existing one already running with 2 GB RAM module with different product Number ?

Thanks.
