Hello community.

I have a 3770K CPU overclocked to 4.5Ghz. It is running on a UP5-TH motherboard. I have the voltage set to auto. It runs at 1.26v according to CPU-Z and CPUID hardware monitor. I have only ran prime for 3 hours. The max temperature has been 81°C on core 1.
I want to know how to reduce temperatures by a few degrees or so. I would put the voltage down as I have seen threads on people doing this to reduce temperatures. However I don't want too put it down too low incase it destroys my chip or something. I don't know much about LLC and such stuff so I cant really decide what too do with all that, so that all is on auto.

Any help would be appreciated. Im not very good with all this since im only 14, and this is my first build.

Thanks everyone.

Low voltage is a good thing, it won't hurt your chip at all. It may slow it down enough that you may need to reduce the clock speed. It seems that the auto programs tend to bring the voltage up more than is needed. For a first step, bring the voltage down a bit. It will run cooler. If the chip still passes the tests, you are good.

Hi, What voltage do you think i should start at? Will 1.15V be a good start with a Prime95 Test for a few hours and also do you think i could get around 4.7Ghz without a high CPU voltage?

Every chip is different. 4.7GHz is starting to get up there. Remember, CPU life depends on the heat generated, the voltage applied, and the frequency of operation. Don't go higher than you really need to. I'd be happy with 4.5GHz. It also depends on your cooler, you don't state what it is. 70 degrees is wonderful and will ensure a very long life. Actually, 80 degrees isn't so bad. If you really want the performance, go for it. You really don't want to be operating at 85 or higher.

For Ivy Bridges, you want the voltage as low as possible. Many times the maximum frequency will go down with higher voltage because the chip will start throttling itself because it is overheating. Power varies directly with the frequency and with the square of the voltage, so higher voltage really heats it up.

I am happy with the 4.5Ghz I have achieved. I was just wondering if I could get some extra speed out of my CPU. I don't want too destroy the chip yet as I only got it back in January. Sorry about that, I'm using a Corsair H100 on High with stock fans. Worth upgrading too the H100i may I ask? I'm happy as long as the temperature don't exceed 85°C like you stated. After 6 hours it's max was 82°C . Dropping the voltages may help reduce that.
I was thinking of trying starting it at 1.2V first, and keep dropping the voltages .05 each time till I get a stable voltage. I don't want too reduce the life of the chip or anything as such.

A small step by step guide would help if you may write one? I will award it with the best solution if it helps.

Thankyou.

You have things the opposite. You need to start with a low voltage and work your way up as needed. Normally you start with the stock voltage, increase the frequency until you have errors. Then you increase the voltage a bit and see if you can go higher. You sort of inch your way up until you cannot get any faster. With you already running the auto, you are pretty close to the optimum setting. As I said, you can probably get better performance with a bit lower voltage.

Oops. Sorry then. I will start at the stock voltage and work my way up till I find the most stable with stock voltages, then il increase the voltage .05 and see if I can get higher. I don't know if it's worth mentioning that I have the 4.5Ghz setting as turbo. So it only kicks in when needed right? Otherwise it's at the stock frequency.
