I have an Asus A8V-E Deluxe board
Previously I had 2x512 KVR400x64C3A/512 DIMMs
I now bought 2 more of the exact same model number and installed them.
My bootup screen tells me I have roughly 1.5 gigs of ram, windows tells me the same - yet when I open up CPU-Z it tells my all my slots are full, each with the exact same type of DIMM, running in dual channel (and therefore 2GB of memory)
I posted here earlier
and this upgrade was suggested.
Is this board not compatible running 2GB in dual channel?
CPU-Z also tells me I've been dropped down to 166MHz
Another interesting thing is that PC Wizard says a total of 2048MB is installed, however when it lists the slots it tells me
A0: 512 (Double Bank)
A1: 256 (Single Bank)
A2: 512 (Double Bank)
A3: 256 (Single Bank)
One final thing, of the two new DIMMs that I installed, one of them is single sided (my old 2 DIMMs and the other new one are Double Sided). Could this be the issue? It is the exact same model number etc.
