Re: z400 - 6 slot memory configut=ration

I can install 3, 4 or 5 of the 4GB DIMMs with no errors, if I install the last DIMM in slot 2,  I get the following errors on boot up:

209 - Memory warning condition (WARN_DQS_TEST) dertected slot CPU0 DIMM2
209 - Memory warning condition (rd dq dqs) dertected slot CPU0 DIMM2
203 - Memory module failed self test and failing rank was disabled slot CPU0 DIMM1
204 - Memory module failed and user rank was disabled slot CPU0 DIMM2


The service manual states the DIMMs to be installed in this order (numbering from right to left) slot
1,3,5,2,4,6.  I have found I can populate skipping slot 2 and it works, however I don't know how much
this affects optimum performnce.
