how to overclock my CPU to 3.8ghz?

I have a i5 3570k and would like to OC it just a bit to see what the temps are like and just to know how to do it. also will need it soon once I get my GPU so I can max out abunch of games.

first a question, "is a i5 3570k at stock 3.4ghz enough to not bottleneck a gtx 780 ever in a game"?

now on to the real stuff. my motherboard (in my sig) came with a OCing guide and after reading it I can't figure it out. the board came a with a OC genie but when I push it in the BIOS it doesn't change anything. and I don't know what to change for it manually. I tried changing the "adjust cpu ratio" from AUTO but there is no other option.

what am I supposed to change to get it to 3.8ghz?

you will probably find you wont notice a difference in any games between 3.4 and 3.8 even with a 780 unless your running across 3 monitors even then it will be the gpu that will run out of steam. as for overclocking go into bios set the multiplier to x38, job done. i would avoid using auto overclocking they have a bad habit of applying way to much volts for what is actually needed!

Its simple. You just change the multiplier. Stock is 34x100 (3.4ghz), to achieve 3.8 you change the multiplier to 38. You need to have an aftermarket cooler when overclocking because the increased vcore will generate higher temps.

As far as I know, pressing the OC button on the motherboard you're using will automatically push your 3570k to 4.2ghz, fully stable, which is more than what you desire. Stock 3570k will cause some bottleneck with a GTX780, thou. Overclocking it to 4.0ghz or above is needed to get rid of it.

If you're having trouble with OC genie not pushing your CPU then try to upgrade the BIOS to the latest version.

yes I have a aftermarket cooler.
the coolermaster 212 EVO. and although im not getting the temps I was expecting its still good and never gets too hot.

its an intel you wont need to add vcore till 4ghz, but yes he has a 212

ok just used the OC genie button to go to 4.2 ghz becaue it wouldn't let me change the ratio manually.
these are the temps at idle with only internet and the HWinfo64 open and cpuz
Current:
core 0: 38C
core 1: 46C
core 2: 36C
core 3: 38C

maximum:
core 0: 44C
core 1: 51C
core 2: 47C
core 3: 52C

core 1 is always the hottest of the cores, usually 10C hotter conssistantly and tends to jump temps around for no reason.
core 3 is usually below 40C but shot up to 50 for like a second then back down. my core temps always jump around like this so that's normal.

here's the average:
core 0: 39.8C
core 1: 46C
core 2: 36.3C
core 3: 46C

my temps have always been high :\

so is this ok? btw the intel hd 4000 was overclocked as well automatically

you can definately do it change settings to manual also if you cant figure that out have a look at vcore etc stock and oc if it varies manually drop the voltage to match stock voltages, but if you cant figure out how to change the multiplier you probably wont be able to do that either

Quite OK, depends on the temperature of the environment, but you need to stress your CPU for a final judgement, using a software like Prime95.

Yep using prime95 and HWinfo64 only.
Typing this on my iPod.

And how's the environment temperature? CPU temp while gaming is often lower than when you stress it with Prime95, and auto OC methods often result in higher temp ( due to voltage often higher than needed ), so unless the environment temp was lower than 10 Celcius degree then your setup is good to go :)

Yeah it's summer here but it's nighttime. Still pretty hot though
According to the Internet temps in my city right now are 73 farenheit
And 23C
