Question regarding voltages and memory oc

post #1 of 5
Thread Starter 
Hey, i read that 1600mhz memory is to low frequency for a i5 4690k so i thought i try to overclock em. Could i try just changing timings (cl9 now would start at cl11) without touching DRAM, VTT and SA voltages. I don't wanna damage something. Here a pic of hwinfo maybe also someone could look at em where i can lower voltages or improve something since i'm kinda new to this. I ran a 864K FFT in prime 95 for 4 hours with these settings. Really afraid doing something with VTT and SA so i left em on auto.

I overclocked my 1866MHz ram to 2400 MHz (2 x 8GB DDR3 1866MHz ram). What I did first is loosen the ram timings, increasing them from 10-11-10-30-2T to 13-13-13-33-2T. Then increasing the ram voltage from 1.5v to 1.65v. After doing that I then increase the ram speed to 2400 MHz. Now the timings that you need vary from ram to ram. Same goes for ram clock speed, you may not get as high as your desired ram clock speed.

I used a bit of Memtest86+ and AIDA64 to test the ram overclocks.

Your VRING voltage reading is probably VRIN voltage instead, a bit weird. It's significantly high if it actually is the VRING voltage so I'd set VRING (Cache Voltage) to 1.150v in BIOS instead of auto just to be safe.

Thanks i'll figure out a cache voltage and start at 1.100

Okay got into windows with 1.145v but was only able to run 576k FFT for 2 hours with 1.160v VRING with a 39x ratio.

Is it safe to run DRAM 1.65v 24/7 and do i need to fix SA or VTT cause when i go up with the DRAM voltage SA goes down. 1.500v DRAM = 1.080v SA vs 1.650v DRAM = 0.865v SA.

Can anyone link me a good explanation how these voltages (SA,VTT and DRAM or VDIMM) work together
