Help OC 3770k+DDR3-2133

[maeggor]

Hi people

I want to stay with my PC one or 2 years more (until Zen4 maybe) I have tried to squeeze my computer but with no success. I have red ansd tried a lot but only I have achieved 4.3 Ghz of OC. Dunno!

CPU 3770k
RAM RipjawsX DDR3-2133MHz CL11-13-13-31 1.50V 16GB (2x8GB) - F3-2133C11D-16GXL
MB ASUS P8Z68-M PRO
COOLER Noctua NH-L12
CASE Corsair Air Carbide 240
PSU HX850i

As I said I reached 4.3Ghz (with all basically in auto) and with this Prime95 gets 80-84º, in games only 76º C top. The RAM I stick on 1600 because I have tried XMP Profile or put on 2133 but Windows doesnt boot.

Mi idea was to get 4.5 Ghz at least and RAM on 2133 or if there is no performance on that speed of DDR3 let it in 1600 but with lower timings!

Any tips, or step by steps guides will be helpfull

Cheers!!!

What voltages are you trying? I had a similar setup and achieved 4.9GHz stable Prime, running at around 1.4v IIRC, same ram speed, no offsets, MB was an MSI.

Hi Robert17

Refering RAM I have just get the problem. I used only 1.5V and need more. So now I have 1.65V and can use it with its fabric clocks 2133.

With CPU now its in Auto and I can see at load it uses 1.220V aprox. for 4.3Ghz. My idea is to get 4.5Ghz or 4.6Ghz, with that I will be happy!

Thanks

You need to take your CPU overclock off of Auto and use manual settings. Start with 1.44 ghz and 1.275 vcore. Test for stability and temps at that point. Your low profile Noctua cooler will probably be a limiting component in your overclocking.

On my old Asus board its auto clocks were 4300 as well. If it helps 1.215 gives me 4500, 1.265 gets me 4600, and 1.35 gets me 4700. You may need more or less..

Put the cpu at 1.5v, then proceed to raise the cpu multiplier by one and boot, rinse and repeat. You will find your maximum quickly. Back the voltage down and then see what you can get stable at a reasonable voltage and temperature. Ideally in the 1.3-1.4v range, but it may be lower depending on your cooling.

1.5v on a 3770K with a Noctua NH-L12? That's crazy talk man.

Don't give your CPU 1.5v. I doubt the cooler would even be able to handle 1.3v on a 3770K.

They get insanely hot..
