Re: A8N-SLI Premium RAM limit

If you populate all 4 DIMM sockets, the board downclocks to 333 MHz by default. I guess that Kingston didn't want to launch into a discussion of this. The work-around is to manually set the memory timings back to DDR400. (You may need to set the command rate to 2T, rather than the faster 1T.)

The web page above has a link to the support page for the mainboard, which in term has a link to the memory QVL (qualified vendors list). That list will tell what modules are verified to work if all 4 sockets are used, but it won't say which ones can be clocked back to 400 MHz.

If you can add RAM that can tolerate an elevated voltage, you may do better in getting back to 400 MHz. I have limited experience with that, but I've had good luck with Corsair memory.

This is what kinston says about the RAM limit.

2 GB using 400MHz DDR modules
4 GB using 333MHz or 266MHz DDR modules

I have a 4400+ with a 200MHz FSB so I'm only looking to add 400MHz RAM, but
what is Kingston saying here? Asus specs don't mention this. But why would
Kingston not make RAM that can reach the limit?
