Hello,

I've now water cooled my cpu with a custom water loop. I want to overclock my cpu as far as it can possible go, at the mo my cpu is i5 760 clocked @ 4ghz (20 x 200) @ 1.27v, my temps are 25'c idle and 45'c fully loaded.

What I want to do now is push my cpu as far as it can go and keep it at that speed stable for 24/7 use but I don't want to kill my cpu.
What I was thinking of doing is putting my vcore to 1.45v and then upping my FSB 5 at a time then using prime for 30mins to make sure it's stable then keep upping my FSB.
I have tryed to up my multiple from 20 to 21 but i keep getting BSOD.
I would like to 4.2 to 4.5 and then start dropping the vcore down to a stable point as well.

What do you guys think? Is this a good idea or bad?.

Cheers
Chris
 
A better idea is increase FSB in 5 increments, and test for stability (Prime95 and a game) for each move up.

When it becomes unstable, move vcore up one level. Try again.

Repeat process.

Ideally if you're looking for 24/7 stability you will need to run Prime95 for 24 hours, and game for a few hours as well (sure you won't mind that! ;))
 
I just posted something similar in cpu forum, but here it is again:

To go for the max for the fun of it is good - but it doesn't come for free. It's widely believed that the stock voltage is chosen so as to guarantee the stock clocks while ensuring an acceptable lifetime. Increasing the volts makes a higher clock possible, but costs (significantly) more in electricity, and reduces this lifetime (no concrete numbers).

There are two approaches:

1. Pick a voltage (say 1.45) and stick to it, and find the max clock. The voltage is arbitrary, and nobody knows exactly how many years it's going to knock off the chip. This is a good strategy if you're happy with the voltage you choose.

2. Go up from stock, systematically increasing clocks and voltage accordingly. If you were very methodical (anal) about it you could have a thorough record of how the chip performs and at what volts. From this you could pick a "sweet spot". For example, perhaps you notice that you hit a wall at x Mhz, after which you need lots more volts, so you would settle for just before the voltage jump.

I've never done 2. as it would take ages. Personally I told myself I would stick to stock volts (a small bump off stock volts actually as it made dividers nice etc.) and settle there. Still much faster than stock, but low power and risk.

Look up the max voltage that Intel say the chip will take.

Set it to that.

Keep increasing the clocks until it's unstable.
 
Thanks for your reply guys.

Last night i started to over clock, i set my vcore to 1.43 and up my fsb by 5 (205) with a multiple
of 20, so now my clock speed is 4.1ghz. I run prime for 12hours and it seems to be stable (i thought
it would be with that vcore) temps still the same as before.

I will be going to work later and i will over clock it it again by upping the fsb by 5, so it will be running
at 4.2ghz.

I will report back and let you know how i got on.
 
hello,
I've taken some picture of my bios setting, i was hoping some of you overclock Pr0's out there could tell me i've got it set up rite.
here are the picture:

please let me know what you think.
thanks
 
Could also mean your memory is unstable (depending which test you have run) as changing the cpu frequency also changes ram frequency. If this is the case you can change your multi from 20 and use a lower frequency for a higher clock.
 
ok thank you. i turned off spread spectrum off as i found out that is meant to be switched off!...
what things would you change by looking at my screen shots i took.
thnak you.
