Hi there im new to the forums, I have an i7 920 and it is currently running at 3.3Ghz my cpu is also water cooled. I have 12Gb of dd3 1600Mhz RAM. My motherboard is Asus p6t deluxe v2.

I would like to make it faster however when i try and increase the speed to 3.4Ghz when I test with prime the temperate goes up to about 85-90C. So i stopped it straight away. Did I do something wrong, why is the temperature so high and how can i lower it. Thanks a lot. If someone could reply with the
settings i should use to achieve about 3.8 I would be very grateful.

These are the settings I used:

Ai Overclock Tuner: manual
CPU ratio settings: 21
Intel speedstep tech: disabled
BCLK Frequency: 170
PCIE Frequency: 100
UCLKFrequency: auto
QPI link data rate: auto

Okay. First off, manually set all your voltages to stock.

Next, make sure you don't have excessive TIM. You should only need an itty bitty thin layer. You shouldn't need more than an uncooked grain of rice.

sorry i dont understand that? could you tell me the things I need to change, or re write the settings i showed? Im real new to overclocking?

Hope this helps.. I highlighted key areas in bold

And like the other guy said.. make sure you don't have too much thermal interface material AKA T.I.M. on your cpu.. refer to this when applying http://www.arcticsilver.com/ins_rout...2intelas5.html

ok i will try that now thanks, other than those two things it should be ok? and what cpu voltage should i use? thanks

ok I set the CPU voltage to, 1.18 its now down to 63C with prime. thanks

You should be using both Prime95 and LinX. A lot of people like to use LinX to find their initial good OC settings, because it will detect instability faster.

Since you have fulfilled the requirements of voltage, temps, and hopefully have good hear transfer to the block (although you should always strive to perfect your TIM technique), as long as when you keep upping the bclk, the temps stay good, all you have to worry about know is stability.

In LinX, do one run with "all memory"; let it finish. Now, leave it all memory, and do 20 runs. If it passes this, it is probably a 90% chance of being stable (off-hand guess), as long as most of your RAM is actually utilized.

Eventually, at some bclk, due to the 12 GiB of RAM, CPU VTT will likely need to go a little higher than it would with 6, if it doesn't need vtt already.

Ah, sorry I wasn't online for a while thanks a lot , and + rep
