Question though, would my 1333mhz limit my overclock? Also how to timings tie into how overclocking works?

Kind of a noob here
No. You can lower the ram multiplier from 10X to 8X or 6X.

I had 1333mhz ram and i still got to 4Ghz. It has since been replaced but it worked fine.

I hit 3500Mhz with 1.152Vcore with my i5 750

first i would reset bios, then s&e (save & exit)

start by changing the voltages for "auto" to what ever stock is. (should say it beside it or something, not sure about your bios)
put the ram voltage at whatever your ram says, i personally dont set the ram timing here, i jsut let them fluctuate during this process. s&e

get back into bios
reduce your CPU multiplier to about 17 or 18.
reduce your ram multiplier to the middle one (dont remember off the top of my head what mine is) s&e

once back in bios again,
increase bclck speed by about 10. s&e

boot into window test with Intel burn test for 2 runs, at 2gb ram

in sucessful, keep increase your bclck by 10 untill your not stable,
then try a decrease in you cpu multi (16), if stable,
keep raising bclck, untill it happens again, then lower your cpu multi again (dont go lower the 14 on the cpu multi)
you will hit a wall with the bclck that wont be stable not matter what cpu mulitplier your at
then decrease it by 2, check stability, if not stable, then drecrease by another 2 untill stable.

thats your highest bclck for the voltage you set
keep this number handy

next.

back into bios, reduce to bclck you just worked so hard to find,
put you ram multiplier at the next level up
put the cpu multi at around 17 again.
s&e
back into bios, raise the bclck by 10, but this time, watch the ram speeds, test with memtest 86, and keep raising bclck, untill you either:
a. reach your max bclck
b. ram is no longer stable
(if you have alot of time, fiddle with the bclck at different ram multipliers)

after youv found the highest ram speed, you can drop you ram multi back down, and then start playing with your cpu multiplier.
doing esstentially the same thing as you did for the ram, except you going to stress test with IBT again.
once youv found all three maxes for the voltages you have set,
you can work setting up an overclock that will be stable in your ram, bclck, and cpu frequency.

again, for questions you can pm me
detailed info as to what your doing/how your doing it would be helpfull as well.

Thanks so much dude, I'll be sure to rep ya when I get on my pc and sorry i haven't responded earlier - been busy with SATs.

Though I will do this, hopefully next weekend I'll have my new heatsink, I've got such an itch to overclock

You guys are all so lucky. my 760 is so volt hungry.. took me 1.3 to get it stable @ 3.9 ghz. Temps are fine though. 73c max when running IBT 15 passes and 4 hours of prime my max was 71c.

Guess I just got unlucky.

not a problem. overclocking is both fun, and addicting tho, watch out

"im not going to fiddle with the voltages"
"ok, maybe a slight bump to get that beautiful 3._GHz"
"screw it, how high can i clock this chip?"
