Overclocking (Questions)
x5ga:
^this. and:
1) Clean the dust inside the case.
2) Remember that cranking up the CPU/FSB/RAM frequency will increase the temperature linearly, while cranking up the voltages will increase it by ^2.
3) If you have a fail PSU, expect your OC'd system to crash when you least expect it.
4) Just because the system POSTs and the OS loads doesn't make your system stable, better run a burn-in test or something for 12h at least after you're happy with your settings.
5) RAM:FSB ratios other than 1:1 tend to suck, so keep that in mind too (use CPUID to check this ratio if you're not sure, BIOS settings might be confusing).
6) Most newer Intel CPUs can be overclocked A LOT (not with the stock cooler though).
7) Adjusting the RAM timings/freq/voltage will take a lot of trial and error, depending on your RAM model. Most are not made for overclocking so you'll have to experiment a lot with them.
8) if smoke comes out, panic.

something to think about:
reference stock speed 2,000Mhz(2Ghz)
[2,020~2,200Mhz] 1%-10% overclock(bump) - hardly gives anything, might as well run on stock.
[2,200~2,600Mhz] 10%-30% overclock(mild) - decent performance boost, not so much taxing for the components.
[2,600~3,000Mhz] 30%-50% overclock(medium) - high performance boost, quite a stress for the components.
[3,000~3,500Mhz] 50%-75% overclock(heavy) - fantastic performance boost, stress are all over the place for the components.
[3,500~4,000+Mhz] 75%-100+% overclock(enthusiast) - monstrosity performance boost, you'll need some serious cooling on your components.
note: buying an aftermarket cooler is highly suggested, even at stock speed. i suggest to overclock below medium first, so no serious damage can occur on your rig.

Thanks for all in the information.
To clear things up, as I posted in the first post (and as vuzedome states), I do use an aftermarket fan. I truly dislike stock fans, so for my rigs I never use em. I also perform monthly preventive maintence on the system, so dust is not a worry. I figure I would benefit from OCing because I do alot of multi-tasking, video and image editting (photoshop and premiere) with some after effects. Plus I play alot of games.
I use Windows 7 64-bit, my memory timings are 9-9-9-24 (they should be set to 7-7-7-21, don't know why I never set them). I also use a Geforce 460 vid card.
I tried overclocking by setting my blck to 170 x 21 (approx 3.7 ghz) with 1.28 volt (default volt on the board) and the system reboots with the message saying that it failed to boot properly and that the computer has fail safes to reset back to default if it fails to boot in overclock. I also tried it with 160 blck and didn't work either. DId work at 145 x 21 (about 3.1 ghz) using default volt. The default clock speed was about 2.8 to 2.9 ghz. So not much change.
I was reading the links that was posted and from what I gather I have to set the volts up a bit to stablize the system?

Please, for your computers safety and your sanity, go to a forum where they do these things on a daily basis.
One such place is Atomic Forums, where they actually have a sub-forum DEDICATED to Overclocking and cooling advice.
I would really hate to see a post where you say, 'This is coming to you from an internet cafe because I blew my PC up' or something along that line.
kitamesume:
set BLCK 150x21 and volts to 1.300v, check your memory speed and timings.
now try setting BLCK to 175x16 and volts to 1.300v, check your memory speed and timings.
if its stable, try increasing the multiplier by 1 each try.
if not, set blck to 150x21 and volts to 1.400v, reduce voltage by 0.010v each try until it crashes. check your memory speed and timings. after crash roll back the voltage by 0.010v.
increase blck by 5. if it crashes, increase voltage by 0.010v.
PS: voltage should not exceed 1.400v as intel says on paper with i7-760 VID Voltage Range 0.6500V-1.400V.
