Sorry to bump this old thread but I have decided to overclock my RAM.
When it comes to RAM from what I've read there are stability tests like Memtest and HyperPI which I can pass, but when I test the same timings and overclock in Prime95 for stress testing it will fail within the hour and BSOD.
This is why I wanted to find out what is the cause even when I am giving volts up to Intel's limit :
(VCCSA 1.1) which shows in HWInfo as VTT 1.184-1.192 (My motherboard has no ability to change VTT)
1.8 PLL as , and applying the lowest of overclock (1800mhz) using the stock timings 11-11-11-28-1. I even changed the command rate to 2T and it failed within Prime95 but still passed one test in Memtest.
I ensured that my CPU overclock was stable and reading on Overclockers UK 8Pack (who is some kind of Overclocking champ with HWbot records) has mentioned an hour stress test is sufficient and then to just play your game. This is how I have approached my CPU overclocks.
This is what I enter into Prime95 to test
My system specs are:
3770k 4.7 ghz
Asus Sabertooth z77 with most recent bios
16gb samsung green ddr3
