i7 3820 - 4820 Overclock Club - Page 141

post #1401 of 6491
I seem to have a problem with hitting 5gHz, even with core voltage at 1.52V. Currently using Asrock Extreme9 as my mobo. I have been able to get 4.6gHz at 1.33V but no matter how much I try I just can't seem to get it stable when I increase the frequency. Is there anything I have left out?

Enabling and disabling EIST and the C states do not seem to make much of a difference.

Does Windows start to load and then fail or does it just get stuck at "Starting Windows" stage?

It would either fail to load or get stuck at "Starting Windows". Any idea why?

Try, disabling all C states under CPU configuration under Advanced option (if you are using preset bios values one of them might be set to auto). Also, increase PLL 1 step (again possibly it is at 1.811, take it to 1.868) and keep memory speed at auto. if that fails try 1333 first and then 1600. Also keep LLC at 1.
Btw; what BCLK and Multi are you using for 5Ghz?

Disabled but will not work. Even with increasing the PLL. I am running it at 40X125. Unsure why but as soon as I hit 4.75GHz with 38X125 the screen will be stuck with a flashing underscore and that is with core voltage at 1.39V

How many memory sticks are you using and which ones? Also is it CostaRica or Malay chip?

I am using three sticks of Corsair Vengeance because one of them was DOA. Would that make a difference? Running them at stock speeds at 1600 with timings untouched.

My 3820 is made in Malaysia.

Ok, take one of the sticks out. That could be causing an issue. Leave 2 and try

Didn't make a difference. Might be a bad chip.

I don't know. If windows is starting to load then maybe it needs a bit more Vcore....
