Hi, guys, I have a few questions regarding overclocking CPU.
Q 1:
I' m using an i5 750 ( 2.67 ghz) on a Gigabyte P55 UD3 mobo and I recently overclocked it to 3.2 (1.120 vcore voltage - lowered it from the default 1.20). When I increased the BCLK to 160 (my multiplier is x20) I noticed that my RAM speed inscreased automatically to 1600mhz, which is running 1333mhz by default. I haven't changed anything in RAM frequences, settings are on auto. Should I configure RAM settings in the BIOS or should I let the RAM as it is now? RAM is x2 sticks 2GB Apacer (1333mhz).

Q 2:
I tested how low the VCore CPU Voltage can go and from 1.20 it went down to 1.50 , but I noticed that CPUID CPU-Z is showing I'm running on 1.120 VCore Voltage. When i try lowering it under 1.15 It also says " 1.120" as well as in the BIOS. Is that normal?
Computer is pretty much stable for now.

Thank you in advance ! : )

Dear,

When you OC your CPU there are some adjustments made to the RAM as well because OCing CPU affects the mobo and RAM equally so system does that in order to ensure the compatibility and stability of the system.

Did your system accept 1.50? If it is showing in BIOS as well then it may not be supported.

Yes, It does. Everything seems fine by now, my main question Is whether i should change something more to the RAM settings, cause now it's running on 1600mhz and 1.61 voltage duo to CPU overclocking. Stock is 1333mhz and 1.5 voltage : )

It is ok with this setting if the system is stable. Leave it be. Change or reset only if system is no longer stable.

Thank you very much :) 

Btw, If I buy another x2 sticks of RAM 2GB (1600mhz) to make it 8GB, will I encounter any problems?
Both new sticks should work fine on 1600mhz, taking into account I'm overclocking my current ram to 1600mhz from 1333mhz, right ? :)

Theoretically you would not run into any problem by adding two more sticks. Pl ensure that their timings and bus speed matches. I've come across many threads where people have bought RAM modules later on and ran into issues like their PC is not powering on or that their new modules are not working etc.

My x2 sticks are Apacer 1333mhz at 1.5 voltage. Should I buy the other 2 same speed and voltage or they can be at 1600mhz, but 1.5 voltage?
Third option is to buy x2 at 1600mhz and 1.65 voltage, but I don't think this will actually run well, cause i'm at 1.61 voltage atm when overclocking.

Any opinion on that?

Thanks. :)

Buy Apacer 1333MHz at 1.5V. They'll OC to 1600 MHz due to system OCing. No issue. All the best.
