I attempted to increase the RAM speed yesterday but it didn't work out.
I activated XMP and then adjusted various parameters, starting from my default 1600mhz. My RAM is Corsair Vengeance 1600mhz DDR3, by the way. I experimented with 1866, 2000, and 2133 mhz settings. I also increased the voltage from 1.5v to 1.65v and changed the timings from 9-9-9-24 to 10-10-10-31. After saving these changes and exiting the BIOS, the system didn’t reboot properly. It tried to restart multiple times before finally working, but my RAM dropped to 1333 mhz (assuming it downclocks after a failed overclock). Since that didn’t succeed, I reset all settings back to default (1600mhz, 1.5v, 9-9-9-24). I then adjusted the timings to 8-9-8-24, but this caused another major failure—my computer didn’t pass the motherboard splash screen! After some panic, I found a solution: I had to reset the CMOS by removing the CLEARCMOS1 jumper and placing it on the second and third pins. Then I held the power button for 15 seconds and reinserted it on the first two pins. My system booted normally, I applied my CPU overclock of 4.1ghz, and resumed normal use. My motherboard is an Asrock z77 pro3, and my CPU is an i5 3570k @ 4.1ghz with stock voltage. What do you think caused the issues? Is my motherboard particularly bad for RAM overclocking, or did I lose my four RAM sticks?
Hello gooeymonster
Your RAM appears to be Corsair Vengeance — 16GB Dual/Quad Channel DDR3 (CMZ16GX3M4X1600C9).
If that's correct, verify your XMP profile in CPUz under the SPD section where it should appear.
Record the settings then apply them in your BIOS.
Check the Command rate; it might be set to 1, adjust it to 2.
If needed, enter the Primary and Secondary Timings manually, as they could differ from your XMP profile.
They should function at 1.5V Dram Voltage, though a minor boost to VCCSA may also help, supporting the IMC on your chip.
