generally you don't want to overclock the BCLK because it overclocks everything (RAM/SATA ports/PCI, PCI-E) and most of that doesn't like a change in speed, frankly the SATA port overclock alone can break your hard drive.
That said you might be able to safely overclock the BCLK +4 - you might be able to get to +6... though somewhere around +6 stuff starts to break... so i'd only go that far if you don't mind breaking stuff.
you'll notice i'm saying MIGHT. there is so many parts with so many different tolerances there is no way to tell at which point things will break. Generally speaking +4 should be safe~ish... but i'm sure people have broke stuff at +4 too... you don't know till you've tried i guess. it's like a game of roulette. Which brings me back to my first comment. "generally you don't want to overclock the BCLK" the return is not enough to justify the risk.

hi sory didn't get back thanks for your info,, I think just to be safe ill leave it at 100.0..... all in all I think I have a hardwre problem maybe hardrive maybe from overclocking to 103.0 but I think it was caused when my uv light swith touched in iside of my case and blew or triped my pc off,,,,turned it back on fine afterwards but been having issues eversince,,,I was kicking myself......is the a way of finding out which hardware conponant is failing,,ie,,drives,mobo,gpu,,,,somthings going on and cant figure it out,,reinstalled windows same problem,,so its not a virus...any clues????

well, i don't know what your problem is if you don't explain whats happening. but yeah, you can usually narrow down what the problem is if you know what you're doing.
what's happening exactly? how often does it happen? can you reproduce it? what are you doing when it happens? describe it as best you can

basically playing on bf3 is were I notice a big performace drop since my insidant....its very jumpy like a memory issue,,,like running and get stuck then run the get stuck constantly but happens very fast,,like stuttering,,,,sorry best I can explain,,,,even on my desktop ive noticed when moving things fast its like my gpu excelaration isn't there.... does this make any sense to you? I have an a p8z68 deluxe,,i7 2700k and evga 680 sc,, I use 60 gb ssd for window but my games are stored in my hdd drive... but general browsing ,,youtube etc is fine its just bf3 but that game uses cpu,ram and gpu,,so don't no where the problem is,,
sorry I cant figure out site,,,,,trying to figre out how to answer and ask questions not long signed up!!!!!!!to be onist m8 im learning never overclocked before I thould id try and help my pc out to play bf3,,,yeh I no its a good cpu I had it clocked to 4.4 and it was nice and stable,,, but my 680 wasn't as good as I thought it would be ,,,I got pci express 2.0 not 3.0 don't no for shore if that's a big difference or not so tried uping the pci express clock,,,,nfortinatly everthing else is connected to it,,,but it made a massive improvement in my game!!!

ok...
The 680 is an awesome gpu... overclock it with msi afterburner.
The i7-2700k is an awesome cpu, and overclocked to 4.4 is nice (not amazing but nice)
BF3 is a bad console to pc port... as such its really cpu dependent. it's not your gpu slowing you down, its your cpu. PCI-E 2.0 x16 is enough for your gpu. There isn't a gpu availible that will fully populate pcie 2.0 x16. so that's not your problem
Since you've got about as good a gaming cpu as you'll find, we're down to certain considerations for improving your performance.
Here are some things to try.
1) your system might be hanging up due to bad drivers. make sure you have the latest Nvidia drivers
2) your system might be hanging up due to overheating, causing your system to downclock. Pop the side of your case open stick a room fan in there and see if the problem goes away
3) you might have a virus/adware/spamware/trojan horse infecting your system and chewing up resources. dl malwarebytes or spybot search and destroy and check for infection
4) your install of windows might be corrupt. fresh install doesn't hurt anything
5) try moving the game to your ssd. see if its a hardware issue with the hard drive.
6) get a better cpu cooler and work on boosting that overclock up to 4.7-5.0, SB can get speeds like that.
7) turn off hyperthreading. i'm pretty sure it hurts performance in BF3

thanks for your help m8 sorry I haven't been I toutch but you certainly no your stuff I think ill do a freash install of window 7 when my new ssd come ,I only have a 60gb ssd so not enough too fit bf3 premium on with windows as bf3 is 37 gb only got 20gb left but I think maybe the hdd is my problem,,,its eather that or maybe when I shorted my psu,hoping it didn't damage everything linked to ie, gpu cpu,ram or mobo who nows,,,but ill try everthing else before replacing my hardware,,again thanks for your help

If you did a fresh windows install and are still getting all the problems you describe it sounds like a weak power supply. Dad had a cheap one which wrecked a hard drive and had smoke coming from the dvd drive after months of un explained errors. It still worked but would surely have done more damage had I not thrown it away.
The motherboard, processor and memory are still in use over 2 years later.
I have a GTX 260 that I have used in a few computers over the years, when I first had it playing games like Crysis I would suffer the same symptoms as you in Battlefield. I have since got into overclocking and found that when benching it would suddenly have a sharp frame rate drop. Running it from a second power supply solves the problem although this isn't necessary at normal speeds. My old computers used to have weaker supplies than I have now which believed caused the issues in Crysis.
Later the same thing would happen in Skyrim with a new less power hungry card. It turned out that time I had damaged the VRM's on my motherboard running constantly overclocked with higher voltge than stock and lots off LLC (load line calibration) causing the board to throttle the cpu. A fresh board solved the problem as did lowering the clocks in the short term.
So there you go, you probably have a weak PSU or a damaged motherboard or both. I doubt that a small bump in the BCLK caused any problems, I run a couple of extra mhz there when benching.
