I do appreciate your responses. I just wish I had asked this before I had a third party try to install the memory. 4 hours late at night wasted because the installer did not do their home work and neither did I. The installer took the memory back and installed it into a system and learned where to install it the next morning. The memory tested good and now I know where to install the new memory. Two heads are always better than one and now both have been educated.

Ok, I'm following now...

That's what I get for trying to pay hardware guy :)

I'll go back to my code now!

Thank you for your response Charles but Sean seems to have understood my question better as he understood that the memory features I quoted include 4 chip and are installed as quads.  I have the lowly power 5, no plus processor, pushing 500 CPW.

Chris,

The system builder redbook I have shows that POWER5 520 requires 4 slots filled.

POWER5+ 520 requires 2 slots filled.  So I'm guess you have a POWER5+
if  you only had two DIMMS.

The redbook goes on to say...
Memory features for the Model 520 with #8325, #8327 and #8330 processors
 #4400 - 1 GB DDR2 Main Storage (2 x 512 MB DIMMs: 533 MHz sdram CCIN 313A)
 #4474 - 2 GB DDR2 Main Storage (2 x 1 GB DIMMS: 533 MHz sdram CCIN 313B)
 #4475 - 4 GB DDR2 Main Storage (2 x 2 GB DIMMs: 533 MHz sdram CCIN 313D)
 #4477 - 8 GB DDR2 Main Storage (2 x 4 GB DIMMs: 533 MHz sdram CCIN 313E)
Requires a minimum of one pair of DIMMs on all processors.
DIMMs must be installed in sets of two (pairs).
For 9405 and 9406 processors, the first DIMM pair goes into DIMM slots
J0A & J2A. The second pair of DIMMs goes into
slots J0C & J2C, the third pair goes into DIMM slots J0B & J2B and the
fourth pair goes into DIMM slots J0D & J2D.

So it appear to me that whomever told you 1+8 would work was mistaken.

HTH,
Charles

Good morning.  Last Thursday I had a failed attempt at having a memory
upgrade performed.  I contracted out the install as the server is 2000
miles from home.  The installer did not put the memory into the correct
locations so the machine did not want to boot.  Our current
configuration has two  #4444 1 GB features and I am removing one of them
and installing a #4449 8 GB feature.  Now everyone tell me that the
system can be configured this way.  I have been searching IBM trying to
find out the exact pattern the memory need to be installed in with no
luck.  Does anyone know which of the 8 slots the memory has to be
installed in?



The final result will be 9GB with one #4444 and one #4449 memory
features.
