I have just upgraded my mac pro early 2009 with an ATI 5870 and an extra 1gig of ddr3 ram.
All seems to be fine no problems all the ram checks out ok and is working but this utility keeps telling me everytime I boot up or log out and into another profile that the memory modules are installed in the correct slots which is really nice to know but does it have to tell me this every time as once is enough.
I have tried moving the memory modules around as slots 1 2 3 had the base ram installed at the factory I then added the extra 1 gig in the 4th slot and started getting the message as stated above. So I swapped the ram around with one of the base ram sticks and put one of them in the 4th slot still the same but when you remove the ram from slot 4 and boot up with 3gig of ram its all happy again.
So I then placed the ram in slot 4 3 and 2 leaving the 1st slot empty and the utility tells me it is the wrong configuration which is fine as thats expected as it will not give optimised preformance i just wanted to see its reaction.
I have phoned apple and they gave me a number for a local shop and the guy there said he has had this happen as well just make sure software and firmware are up to date and it should clear which of course they are and I have double checked.
So for now I went into system on mac HD and then into core services and removed the memory slot utility and placed it somewhere else for safe keeping and it has stopped now but thats because it can't use the utility.
I am stumped I can't see this being hardware it seems it could be software or a bug not sure either way I am covered under warranty but I just want to get to the bottom of this other people have reported this on these forums but not mentioned how they got on.
My next step is to reinstall lion I have my old osx leopard cd's also and then I can reinstall everything else from scratch but this seems extreeme
If anyone has any ideas I would be really gratefull
