Surely not more Vcore!!

post #1 of 15
Thread Starter 
hey everyone!

Ive spent the last few days trying to get stable at 4.5ghz to no avail. Prime95 failed after 4 hours due to rounding error so im now stumped.

Vcore levelled at around 1.384 with LLC on with turbo and EIST enabled and temps were quite reasonable peaking at 70 on a single core. Surely this chip cant want more vcore? Think i may enable PLL overvoltage and see what difference that makes

PLL overvoltage is just for getting past a multiplier wall if you can boot at 45x you don't need PLL overvoltage.

Might be RAM related ...

Check the timings and VRAM for your specific RAM modules.

Have you run memtest+ ?

Bump up vccio to 1.1 and if you are OCing your ram, bump up vram a notch or two and try again. A bump in vccio allowed me to drop my cpuv a bit as well. Are you using XMP settings (retail settings) for ram voltage and timings?

Hi cheers for the advice I left all ram settings at default having read some guides.

edit:cheers for the guide thats what ive been using as my base I have upped vccio as suggested and set ram timings and speed manually to their defaults.

Try taking CPU PLL Voltage off auto and manually decreasing it. Start it at 1.55 and slowly make your way up. A lot of people (including myself) have found this to be a successful way of staying stable with a little less vcore

Cheers for the advice mate although I believe my board only has an option to enable or disable PLL voltage :/

I set offset and ATV to auto to see what the board wants to do with them and its running at 1.408/1.416 at the moment in prime95.

not PLL overvoltage (which some have) there should be a specific setting for CPU PLL Voltage
