i5 3470 Overclocking Question.

post #1 of 2
Thread Starter 
Hi everyone, I am Kind Of new to overclocking and i was wondering if i could overclock my 3470, I have a COOLER MASTER Hyper 212 EVO And was wondering how Far i can OC it and what software to use, Thanks In Advanced.

~My Motherboard is a ASUS P8z77-v LK

you'll be very limited with how much more you can get out of that 33470 as opposed to a 3570K - the multiplier is locked. and please don't use any software, going to the BIOS is the best way. to get there is hitting the DEL key when you boot.

you would look for the turbo boost setting and change it from manual to "all cores OS can adjust" and then raise the number to 38, or as high as it can go. that will allow your cpu to go faster than the "out of the box" settings. you could also raise the BCLK slightly from 100 to 103 and with a 38 multi will give you 3.9ghz. but i will warn you, raising the BCLK too high can result in corrupting the data on your hard drive, cause you GPU to get weird or even damage it under certain circumstances. but i have had two different asus boards in the last year and neither of them had a problem with 103. actually i think you have a OC button in the BIOS that will automatically do that.

you could use some software to monitor the speed and the temp of your cpu like cpu-z and core temp. also you ought to stress the cpu with prime95 to see if it is stable and the temps don't get too hot when under a heavy load.

your cpu will be able to handle a 3.8 - 3.9 clock speed but the next step would be getting the voltage lower, because auto settings always give it too much, so the temps stay as low as possible. that really is best done by using the "offset" that is also in the BIOS. i have mine set to a negative 0.12 so when i am idling i am not putting more volts than needed since the clock speed lowers to 1.6Ghz

BUT your may/will be different, finding what it is will take some time. sorry i don't have the time right now to explain it to you. but there are a few guides around that will be of help. but the basics is looking in core temp and seeing what the VID is; that is what your cpu is saying it need for voltage. then looking at cpu-z and seeing what you cpu really is getting. write down both.

then go into the bios and change the offset from + to - and adjust one increment from "auto" (well maybe a couple of bumps to start) then see if you post and boot into windows. run prime95 for a good 20 minutes and if no errors, then wash rinse repeat going into the BIOS and adjusting the voltage offset.

in the meantime make sure you write down your adjustments because if you fail to boot or crash because it was too low, it would be helpful to know where you left off. and there will be a likely chance that you will fail to post or crash. inbetween each time run prime95 for 20 minutes. when you get to the point of getting your voltage low and you posted and booting into windows then run it for a good 3+ hours to be sure.

BUT MOST OF ALL HAVE FUN! thumb.gif

its bedtime for bonzo - good luck
