Ram problem

Greetings,

I'm trying to get ram working on an e7500 MCH.
It seems to be actually initting, but when I run ramtest it, I
consistantly see a single bit toggled when reading back such as:

00024ab4:00024a94                                                               
00024abc:00024a9c                                                               
00024ad4:00024af4                                                               
00024adc:00024afc                                                               
00024af4:00024ad4                                                               
00024afc:00024adc                                                               
00024b14:00024b34                                                               
00024b1c:00024b3c                                                               
00024b34:00024b14                                                               
00024b3c:00024b1c                                                               
00024b54:00024b74                                                               
00024b5c:00024b7c                                                               
00024b74:00024b54                                                               
00024b7c:00024b5c                                                               
00024b94:00024bb4                                                               
00024b9c:00024bbc                                                               
00024bb4:00024b94                                                               
00024bbc:00024b9c                                                               
00024bd4:00024bf4                                                               
00024bdc:00024bfc                                                               

Other times, I see that the second read (in order to display the bad
value) actually reads successfully such as 000127a8:000127a8

Does anyone have any ideas what might cause that?

G'day,
sjames
