nick I honestly don't understand how you are posting this question. I've answered this for you on 3 seperate occasions writing very lengthy and detailed responses....you need to read up on how computers work and what overclocking really is.
This is the last time I'm going to tell you: You CAN , but when you OVERCLOCK you're also overclocking your AGP and PCI busses....you will need to LOCK those busses to make sure they don't get overclocked when you start raising your multi.
Seriously dude, You don't read enough as it seems so I don't think you need to be trying overclocking just yet. I've answered this question for you two or three times now and you're asking it again as a seperate thread? I told you I have the 2400+ and explained it fully to you.
Default: 15x133 the multiplier is LOCKED you WILL NOT be able to change the multiplier.
As I've said for the 4th time now...you can TRY to get it up to 166 but you need to have the option to lock your AGP and PCI Busses which you do have on the NF7-S2G board. Notice keyword is TRY there. Do the math man...15x133 = 2GHz, now try 15x166 and see what you come up with.....2.49GHz..that's a huge jump. I can't stress enough that you need to do more reading if you can't even understand the advice I give you on the subject multiple times.
I answered everything in your previous forum post here:

Obviously you need to do some series reading. Start with kangaroo's basics on overclocking in the overclocking section.
EDIT: Hey moderators, if you're gonna post peoples reviews then look through them cause look what one guy said:
if you want great performance lower the multiplier from 15x to 14x....then up the vcore to 1.775,
.....this kid doesn't know anything about overclocking obviously......THIS CHIP IS LOCKED, you won't be able to change the multiplier down to 14 unless you plan on doing some mod to the CPU itself using an X-acto knife, magnifying glass and some conductive paint...which I highly would not suggest you trying to do.
