Just trying to breath some new life into an older PC which is used as a second computer.
I am trying to overclock an Intel Xeon X5470 on a Gigabyte GA-EP45-UD3R
I would like to achieve a 4GHZ overclock, or if not possible the highest stable overclock under 4GHZ. At the moment I have a 3.6GHZ clock.
My RAM is quite slow as I have Crucial DDR2 CT2KIT51264AA667 667 MHz ( PC2-5300 ) 1.8 V. I have 16GB of this RAM (4 modules), as that is the largest DDR2 RAM I could find in 4GB modules. Problem is it is not so fast, but I need 16GB RAM for video editing.
Could anyone suggest some Bios settings that may work for an overclock? Even if I could not get 4GHZ, any improvement would be welcome.
