1GB @ 133MHz compared to 768MB @ 175MHz
The 768MB would be "faster", as having [i]more[/] memory does not increase speeds.. just means you have [i]more[/] memory.
Ninja, i really hope your NOT using memory dividers, because unless you're overclocking your CPU by a good 400MHz you won't see a performance increase but a decrease.
And i presume that your memory is PC2100? (133MHz=DDR266) by default, or is it PC2700 (166MHz=DDR266)?
