Z87X-D3H Memory overclocking

[mgaming]

Hello,

I'm overclocking my RAM with Z87X-D3H mobo. I can change the XMP profile, however I cannot find anywhere the "Profile VTT Voltage" setting, as if it is were hidden.

If anyone knows how to reveal it, I would be grateful.

Thanks.

VTT voltage is the MC (memory controller) voltage, on the Z77 chipsets it's normally called VTT or CPUVTT, on the Z87 mobos it's most often incorporated into the VCCSA (system agent voltage)

Should I set the System agent to 1.3V if my memory is at 2133? Like in here http://www.techpowerup.com/reviews/Kingston/HyperX_Beast_2400C11/8.html

No, that's way to high, you have a Z87 and the example you are looking at is a IB CPU combo, and that's even high for those, 1.2 is about the mx you want to go on a Z87 and shouldn't need more than 1.1, I've got 32GB of 2666 on my Hero and the VCCSA is under 1.1...the example is also Kingston sticks, those aren't really sticks I'd OC myself, you generally have to give up to much in CL to go up a step and do it safely

I have Kingston Hyperx Beast (2400) 4x4 (16GB)

When I use XMP profiles like 2133 it still crashes maybe once a day. With 2400, much more frequently.
My proc is i7-4770.

Do you have the latest BIOS? and what CPU?

 

[mgaming]

yes bios is F7, CPU: i7-4770

Should have plenty as far as MC voltage, could try increasing DRAM voltage + 0.05
