I bought a new system last friday and it shipped from newegg and came two days ago. I Built it on a EVGA 680i LT MoBo and I have a E6750.

I don't see the regular FSB ratings and i've searched throughout the BIOS. I have a Phoenix Technologies Bios 6.00Pg, bios.

Here are the screenshots, im not completely new at OCing but I don't see any regular FSB options? Can anyone offer me some help, much appreciated, thanks in advance.

Oddly enough it looks greyed out.

Try this:


Advanced Chipset Features -> FSB & Memory Config -> Change FSB -Memory Clock Mode to Linked or Unlinked. This should allow you to change the FSB and Memory values.

Edit: Also, all I did was go to eVGA's site, open up the manual, and look for it.

I did mess around with the linked or unlinked, nothing ungreys it? Well the top stays greyed out but the bottom lets me edit a 1333 FSB. Just curious as I may sound like an idiot, but shouldn;t the FSB be 333 x 8 = 2666 ?

FSB is not CPU speed. It's Quad Data Rate, or four times the Bus Speed, all the time.

Editing the QDR FSB of 1333 will let you overclock because a QDR FSB of 1600 will be a bus speed of 400, which for the CPU will be 400x8 or 3.2 GHz.

Read the stick at the top of the page, please.

I don't think you're looking at the right place to change the clock speeds...there's a good sticky on how to overclock on the overclocking section.

I had a similar problem with my old pentium D Evilonigiri is right you're going to the wrong place try messing around a bit. And if you're not using sli try changing you're mobo to P5K i got one and ther're really good for overclocking.

Yeah I overclocked a bit and got it to 2.9 with stock volts.

But thanks, i'll see its limit in a while, im using a tuniq tower 120 so on Crysis full load on 2.9Ghz it went up to 35 celcius.
