4GHz i5 760

[Caveman656]

Hello, I'm aiming on getting my i5 760 up to 4GHz. It's already overclocked to 3.6GHz, but when I try 4GHz, I increase my vcore and increase VTT a little. When I save and restart it says that the overclocking has failed.

Am I doing something wrong? Also I CAN'T change my cpu ratio, it's stuck/locked at 18. It says that it's unlocked but I still can't change it.

I'm using the MSI P55-UD65 motherboard if that's any help.

If you want pictures of my bios please ask.

Thanks.

What sort of volts are you feeding Core and VTT? and also, are you lowering your RAM multiplier to remove it from the equation stability wise?

You can feed both the Core and VTT about 1.4V ~ 1.45V without worries with a good CPU cooler.... Which CPU cooler are you using by the way?

Enable load line calibration to battle vDroop and keep pushing that BCLK up and up you should be able to get 210 easily.

As for your multiplier issues I would need to see a couple of BIOS screens to look at the various settings etc to see if if anything needs to be enabled etc.

I'm feeding the core around 1.3v, and with the VTT I was just knocking it up a little. I was keeping the RAM multiplier the same.

I'm using a watercooling loop.

try with around 1.35V ~ 1.4V on VTT and 1.4V ~ 1.45V on CPU Voltage and then try increasing your multiplier one step at a time and bring the Base clock down to 200 (I see you had it at 205).

That's the thing, I can't change my ratio it's stuck at 18, I can't move it down or up.

Have you got any idea how I can change it.

Give the rest of the chipset s'more volts too. I don't know the naming of stuff for Intels but unless VTT is the same as VDDA, you'll want to up the VDDA aswell

Could you give us the CPU options you're given in the BIOS and what they're set at? Could prove useful.
