The A320 Chipset is 32Gb RAM limited. It's really an office motherboard and only has 2 dimms.Do you know which motherboard it is? I ask as Currys/PCWorld don't always list things correctly. I just tried looking at what motherboards would be most likely used but can't find any that are 32GB maximum...unless it's an older CPU that is RAM limiting the motherboard. It is likely you could probably get 4x8GB in there as most (not all though) motherboards have 4 RAM slots but you'd need to find an exact match to the ones already there
