Simple multiplier increase will . . .

. .. result in the world's easiest, quickest, and safe O/C. True or False ?

i'm a total noob on this. i have a Q6600 on a Giga x38. and i'm looking to score
my first successful O/C. help please.

Only if you have a cpu with unlocked multi's (unlocked upwards, most aren't).

Otherwise, the simplest, easiest, safest oc would be raising fsb X1 Technically, 1fsb over stock is oc'd

Seriously though, raising fsb is the simplest way to oc. There is a lot more to it, but a very mild oc can be accomplished this was without having to worry about ram speed, voltages, etc. You can then keep learning and start pushing further.

This bios quide might be of some help. Dont worry about the testing etc. but go thru the bios settings so you understand what is going on.

Then post back after you have done the bios setup with your memory settings and voltages and the options set up the way you want for your hardware. Per above, you just start raising the FSB while watching temps and memory speed. It is not hard to get a basic OC out of a C2D but there are a few things you need to watch. You will have one or two settings not mentioned in the quide, just leave them at factory defaults, they are not necessary for a first stab at OC.

Only Intel's Xtreme or AMD FX CPU's have unclock multiplier, everything below that is locked.

To answer your question; it's true

So when you say the multiplier is locked does that mean the multiplier cannot be changed? I was under the impression that multipliers can be lowered but cannot go above the stated one?

E4500 is 2.2Ghz= 11(multiplier) x 200(FSB). Now I have a set of DD2-800 RAM and want to run this on a 1:1 ratio. That would mean increasing the FSB to 400 and decreasing the Multiplier to let say 8x to reach a 3.2ghz Overclock. Is this possible if the multiplier is locked?

You can decrease with locked multiplier CPU but CAN NOT increase it. Yes you can change the muliplier of E4500 (just down).

thanks for the ideas.

oh, ofcourse. locked multiplier . . . i overlooked that basic because i am among the unheard (and embarrassed) people who tried and failed in their previous attempts that i walk away and just appreciate the fact the rig functions smoothly.

BUT . . how large a bump can i give the FSB to start with ? I am under the impression some of you just kick it 200 points up instantly. Not 1, 5, 10 points up, slowly carefully, testing (?) along the way, but BAM !!! 50, 100, 200. At what point must you (must you ?) increase the ram speed ?

i have 2 gigs at 800mhz, GSkill, gaming memory. My CPU is Q6600. I need to break this down in my own baby-like fashion if I ever hope to understand anything. these guides assume to much awareness, knowledge, intelligence or just mere consciousness for me to absorb and apply what they teach.

(F)ront(S)ide(B)us x multiplier = raw speed of your pc in mhz (or ghz)

the Q6600 is locked therefore it has a maximum multiplier of 9.

The stock FSB of a Q6600 is 266 so the formula is 9x266.

You set the multiplier lower if you want to try to achieve higher clocks using front side bus rather than multiplier.

Note that any kind of changes to the FSB or multiplier may need a voltage adjustment so make sure you read thoroughly about this and learn as much as you can about your bios before doing anything.

If your system becomes unstable you may also want to read up on how to reset your cmos.


To 'simply' put it, there is NO simple way to overclock. You have to learn about your board and what overclocking is before you go and do it.

Don't be that guy that thinks putting an additive in his car gives him 10hp..

I'm not sure how exactly individuals do it, but part of that comes down to the speeds you're expecting to get; you can go in relatively large jumps initially, then as it gets increasingly high, increase the FSB in smaller increments. For instance, I'm in the process of taking my Q6600 from 2.4 - 2.5 - 2.6 - 2.7 - 2.8, then 2.85 - 2.9 - 2.95 - 3.0, and would probably go slower again over 3.0. (At a 9x multiplier, that's approximately an increase of 11Mhz on the FSB for a 100Mhz increase in processor speed.) The level of caution involved will depend on how confident you are, how good your cooling is and whether you have experience etc. I've not done much overclocking in the past myself; I wouldn't be surprised if others would miss several of the lower steps.

It's not really a good idea to overclock the RAM at the same time as the CPU, because if it starts failing you won't know what the problem was. Some people advocate running the RAM at 1:1 (the same speed as the FSB, but because it's DDR RAM, its effective frequency will be twice the FSB), but because I'm doing this slowly and using my machine in the process, I'm just keeping the divider as near to my RAM's rated speed of 800Mhz as I can without going over it.

lol, i know all about system instability vis-a-vis overclocking. i've learned terms like 'residual electricity'


so . . . Important Numbers To Know ------> Nine and 266 = 2394.

Example: multi of 8 x FSB of 300 = 2400, a super-overclock of 0.6 ! !

Example: multi of 9 x FSB of 275 = 2475.

how high do you think i can dial up the FSB, leave the multi at 9, and not have to adjust voltages on a Q6600 (Go edition) ?
