I just purcased a set of Kingston HyperX KHX3200AK2/2G for use in my Asus A8N-E. However, the DDR400 ram is detected as DDR266!, and the timings it automatically selects are 2-2-2-6 (at 266MHz)...

Strange. I've tried to force it to DDR400/2-3-2-6 at 2.65V and DDR400/3-3-3-8 at 2.6V (and some other combinations), but in all cases, the system just gets unstable.

Asus Award-Phoenix bios does have a lot of other timings to set than just these. Like - Row cycle time/Trc, Row refresh cycle time/Trfc, Read-to-write time/Trwt and Write recovery time/Twr - but I've found no indication anywhere of what they should be set to when manual.

It should be noted that I also have a set of KHX3200AK2/1G (2x512MB, PC3200/2-3-2-6/2.6V), these are detected fine. But the 2x1GB pair forces the system to 266 whether they are alone or together with the 2x512MB.

If anyone have suggestions to what I can do - tools for testing the bandwith/effects of latency etc. it might be helpful. Right now I've send a report to Kingson and awaits their response - if I can't get them to go 400MHz, I'll decide whether to return them or what...
