DDR2 and ETHERNET on DE3 (Stratix III)

I have 2 demonstration example: DE3_260_DDR2_1G_1RANK (come with DE3 CD), and DE3_NET_260_GMII_NET0 (come with Ethernet-HSMC Card CD). both of these examples are works fine with the same configurations.  

 

 

The configuration of DDR2 SDRAM High-Performance Controller (SOPC IP Core) in both example are different: 

DE3_260_DDR2_1G_1RANK: 

1. Use High Performance Controller version 2 

2. Change board setting values 

3. Use custom preset which specified for DDR2 1G  

 

 

DE3_NET_260_GMII_NET0: 

1. Use High Performance Controller version 1 

2. Using default board setting values 

3. Use custom preset which specified for DDR2 256M  

 

 

 

I am working on DE3_NET_260_GMII_NET0 and I have DDR2 1G (not 256M) and in SOPC they recommending me to use High Performance Controller version 2, so I change DDR2 Memory Controller configuration to be like DE3_260_DDR2_1G_1RANK configuratio. the compilation of quartus is pass, and when I programmed Simple Socket Server example I face error (in the attachment). 

 

any help, please. 

thanks,
