Overclocking i5-3470 to 4Ghz - Page 2

The governor on the chip will only allow a multiplier of 38 on every core at the same time. A single core can have a multiplier of 40, but the other cores will not have this multiplier and/or they will be in a halt state.

Bclk has nothing to do with the multiplier the chip will allow. But yes, it's 3.8 at 100 bclk and ~4.0 at 105.

If you do not touch the Bclk, the max you will see is 3.8GHz on all cores.

Ok, so I got the system up and running. It crashed and went into a boot loop when I set the multi to x40, oh well... It runs perfectly with multi x38 and turbo boost / intel enhanced turbo ON. What bothers me a bit is the 40C idle temp, but I guess that's what Ivy bridge does...

Odd, my multi is set to 40 and it works just fine (at 3.8)

You may want to look at your heatsink mount. I'm using a stock 1156 heatsink with the fan upside down and don't have any issues.

Done a lot of trial and error work. finally managed to make a stable overclock on the 3470 non k series...... tested it with prime95, temps did not go over 40 degree c..... no troubles with booting or anything, runs like a dream.

let me know what you guys think. im not a real big overclock guru, this is really one of my first attempts at overclocking, and just tweeked my settings based on info i was reading about the non k series 3470 and what other people have attempted.

also, this is my second comp build ive done and decided to water cool as well and go gigabyte 7870oc crossfire as well.

Probably not as the h77 boards I've seen don't allow you to adjust the multiplier at all, regardless of what the cpu will actually support. There is always the BCLK option, but again the boards don't usually support it.

Hi, I know it's an old topic but I was wondering how to do it the easy way, as this processor supposed to be locked for oc i thought it will be difficult but it is supper simple. Please look at my screenshot bellow:


I just used easytune 6 from gigabyte and selected option 3 for maximum possible in 'auto mode', pc is stable and you can feel a lot of boost in the performance, also stuttering on my 7870ghz oc edition finally gone away.

BTW all options regarding oc on my bios were inactive the only thing I could activate was ram boost to 1666, this was the reason I was looking for some other way to oc that proc.
