table is full

[scott hathaway]

I am trying to get a table into memory with the following:

create table ws_mem engine=memory as select * from winsite_report1

I get the error: 1114 The table 'ws_mem' is full

I am using the latest MySQL 64 bit for Windows and have 16GB of RAM on the server.

Here is my my.ini:
[client]
port=3306

[mysql]
default-character-set=utf8

[mysqld]
port=3306
basedir="D:/mysql/"
datadir="D:/mysql/Data/"
default-character-set=utf8
default-storage-engine=myisam
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
max_connections=160
query_cache_size=2000M
table_cache=320
tmp_table_size=8000M
thread_cache_size=8
myisam_max_sort_file_size=100G
myisam_max_extra_sort_file_size=100G
myisam_sort_buffer_size=1000M
key_buffer_size=1000M
read_buffer_size=64K
read_rnd_buffer_size=256K
sort_buffer_size=256K

Can anyone help me get this table into memory?
Thanks,
Scott
