i can only hit 4GHz but using 211 x 19 and running the ram underclocked. got a few days off work starting sat so will have more time to play, but wondered if anyone had any ideas whats going on.
4GHz i7 920 D0, but only on 19x

nope coz im not too sure whats safe to go to. i havent done any serious overclocking for years so dont really know whats the best settings to go for, and whats 'safe' max voltages.
ok cheers will try playing with those figures.
i only use OCCT as when i had my Q8300 intelburn seemed to show it was stable, but OCCT kept failing, so lost confidence in intelburn. not sure if OCCT is a good enough test, but have been playing fifa 2010 and NFS:Shift all evening and no issues thus far.
You're not supposed to just set it at any fixed setting, you should be testing by increasing one step/notch at a time, that is one of the main principals of overclocking afterall.
My QPI is at 1.455 so you have some head room yet
NOTE: don't just put yours to 1.455 for 2 reasons
1. I have RAM that needs around 1.9v and the QPI needs to be within .5v
2. You just should't do that.
i had the same setup (different ram but mine was quicker) so i used their settings and tweaked them. i have been going up and down on the vcore as i know that 1.35 is pretty much the max you want to go, likewise with other settings i have read whats a safe figure to max at. but there are still some settings i am not sure on, still a big learning curve, but dont want to keep upping it bit by bit if i have reached my max oc and end up killing something.
my ram is 1.65v, so does that mean i can only go to 1.1v?
sorry struggling to get my head around it, so if my ram says it should be 1.65v, what can i go up to for the QPI? or is there not ratio, i think im confusing myself now.
ok thanks, could it be my ram settings causing the problems?
my ram is rated as 1866MHz, can i not run it at that?
so does that mean my mobo is probably limited to 3.8-4GHz?

will try and lower my vcore to see if i can get temps down.

well i lowered vcore and it BSOD, now when i go back to those settings it says NTLDR is missing, put it bacl to 19 x 211 and it loads fine 
are these settings ok, will running a lower multiplier do any harm?

like i said, i am going by someone with the same setups settings.
last time i did any overclocking was when you only really needed to change vcore and fsb, and you never really went too much higher.
i dont want to go over 1.3 vcore if i can help it though, but could this be the problem?
I was setting mine at 21 x 181 for 3.86GHZ, vcore 1.27500 and qpi on auto with ram volt or 1.66 I did prime 95 for 4 hrs no errors no reports and max temp on full load was 69 degrees..
Last night I got a little freaked out as I have this horrible feeling that my system may blow up with the voltages lol .. I never overclocked before this was my first attempt.. but thought to myself "is thee really any need for overclocking for what I use the pc for (photoshop, lightroom, movies etc..) I am not a gamer by any means..
However the thought of having it run at 4.0GHZ just makes you want to have it.. so would you guys reccomend I set up again tonigt? This time at 21 x 191 , turbo enabled , vcore 1.30000 (or shall it be lower) timings for my ram is 9 9 9 24 so I will set them too what should my uncore and qpi multiplier be also what should my ram volt and my qpi and ioh voltage be . pleaase guide
Thanks ..
PS: when I was hitting 3.8 GHZ there were 4 little blue lights constantly light up when pc running on the top right of the mother board which I think indicate the level of overclocking .. is this safe? how many blue light should it be max? and there was a small green light which was on by the ram when I put the ram voltage to 1.66?
what mobo do you have? is your i7 the D0 or C0? what cooler are you using?
paradisiac still waiting for your assistance please mate
not sure what the lights mean, will look in my manual tomorrow. as for overclocking, whats you target clock? i wanted 4GHz or as close as i could get, so having to go to 19x to achieve this to me isnt a problem as longs as i dont loose anything by having a low multiplier.
did you have it stable at 3.8GHz?
aslong as you leave speedstep on, then it wont be running at the 3.8GHz all the time its on, infact, it will run that hardly ever if you are mainly downloading. as for the vcore being too high, you are good up to 1.34 vcore i believe, so below that is good, i got mine down to 1.200 vcore @ 3.7GHz. the ram should be fine aslong as its not over the sticker voltage. not 100% sure on the qpi myself so i went with what someone else had done on their setup, but will have a bit of a play as i have 9 days holiday now.
from the settings you have said there isnt anything that would worry me, and as for the electric bills, like i said, with speedstep on it shouldnt make any difference from stock settings and 3.8GHz unless you are doing something cpu intensive, which downloading wont be.
my 3.7GHz settings were :
like i said though, some of those settings i got from someone else so i dont know if i could change something for the better, but it got me stable at reasonable temps too.

the uncore freq will have to be x17. other than that its a base to start from. not sure, cant see leaving qpi on auto will do any harm, so unless it becomes unstable then leave it at that.
