XP system properties *solved*

Solution
DownLoad Cpuz and see under the memory tab. Look like on your screen shot the CPU is running at 800mgz. In CPU z 1333 ram will say 677 some times. 667 times two is 1333.
yes sorry you're right it's one of the CPU cores that's displayed - overlooked that - just woke up >.<

yeah there's four detected in device manager i think it's OK

i think the reason i was suspicious is because XP runs quite slow - im trying to move to linux
