Hello all,

I'm trying to get the Asus M2V-MX SE working (K8T890/VT8237S) it has AM2 socket.
CPU is semperon model 127 fam f

Currently there is some problem with memory, I have attached the log.
I have no clue what might be wrong. The module is 512MB 533MHz single DDR2 with
CAS4. The FIDVID changing and fidvid setup is disabled, reset of HT is disabled.

It seems to fall down the drain on very same place.

Any clue? Maybe I have some options wrong? What should I check please?

I checked I2C reading and they are correct (I verified with EEPROM dump)

I dont understand why:
...
Setting variable MTRR 02, base: 0000MB, range: 0200MB, type WB
...

The range is only to 200MB ???

export MEM_TRAIN_SEQ:=0

I have no other DDR2 module to check.

Thanks,
Rudolf
