i7 3770K on Asus M5E + 2.4ghz ram

post #1 of 5
Thread Starter 
I'm updating my knowledge on the current policies of OCing on IB CPUs but there is something that is still unclear.

I have an Asus Maximus 5 Extreme which is able to clock ram at 2.4ghz, so I bought some 2.4ghz RAM (Corsair Dominator Platinum) just to have something that is enough powerful and tested without deciding the speed at which I would run them. Right now I'm realizing that tested voltage of these DIMM is 1.65V but according to what I've read around the MCH of my cpu (3770K) is meant to run at 1.5V.

According to Intel it is unsafe to use 1.65V but at they same time they promote the usage of XMP which sets the voltage to 1.65V to run the banks at full 2400 mhz.

So should I just keep them at 2.4ghz with 1.65V? How does it degrade the life of the CPU? Does it produce more heat? On the other side should I just keep them at 1.6ghz (which is the max clock allowed for the CPU) and revert back to 1.5V?

Thanks in advance

Having to take care of the RMAs, Intel wouldn't want to advertise overclocking or overvolting in any way. However, 1.65V is perfectly safe for both CPU and memory - feel free to use that.

So it won't burn my 3770k although max stated is 1.5v with a tolerance up to 1.575v? Otherwise I could try testing stability by lowering the voltage that is given from the XMP profile (eg from 1.65V to 1.575V) and keeping them at 2.4ghz to see if DIMMs are still stable but I don't know it is it worth trying, I guess I would gain just some CPU life span, nothing more, am I right?

I run mine at 1.65v with same processor. NO issues.[IMG ALT=""]

1.65v IS PERFECTLY SAFE! No worries!!! thumb.gif
