I have a Gigabyte GA-X58-UD3R. When I try to add more memory I get the following problem. The slot 4 does not indicate a DIMM but enables it. This is reproduceble for many differnt combinations of the DIMM moduels and also for different configurations.
Any suggestions please
well all modules are 4 GB. they are matched 3 by 3. I can make the sytem find (beside the starting 12 GB) 16 and 20 GB but as soon as I have slot 4 occupied it (the bios) claim not to see the DIMM but it enables it. The bios displays something like this
The piece that it does not enable slot 3 is normal as this configuration disables this slot. The behaivier that it does not see that there is a DIMM in channel 4 but still enables it is consistent for 4,5 and 6 DIMMs
well I keep the matched tripples in 1,3,5 or 2,4,6 they are the same but with different version numbers. Same model number and timing. I have only systematicly tyed 2 from each set in slot 4 but before I started out by systematic test I may have had others in that slot.
further I do not normaly run Windows. But the problem with the suggestion is that the boot process do not pass the "calylating RAM size" stage. this means I can start no OS with a memory stick in slot 4
