Hello, I tell myself that sometimes, I will find an answer here ... :) My workstation is a first generation HP Z1 workstation. We switched to Sw 2019 and at the same time I asked to give this pc a facelift by adding RAM ... I only had 8 GB (2x4)...
So I installed my 2 new sticks (2x8 GB) in the same slots as the old ones and I thought I could keep my 2 old ones in addition for a total of 24 GB ... But in vain, I can't manage to accumulate my bars. In theory I can put up to 32 GB on this pc, if I'm not mistaken. but when I put the 4 strips on the other 2 slots, I have 5 beeps at startup... I tested the 2 sets of strips, independently on the other 2 slots, it works too... I have 2 Black slots, on which were my old ones and on which my new ones were connected, I have 2 other beige slots, which take my strips by 2... but the pc doesn't like it when I put the 4... Note that my sets of sticks are not of the same brand between the new and the old ones. Is it a parameter to be set in the bios or is it because of the difference in memory... However I checked at home on my personal pc, I have 12 GB in 4 sticks that don't even have the same frequency, on the other hand they are of the same brand ... If anyone has an idea ... Thank you in advance.
