Can't Set Multiplier over 33?

Thread Starter 
I was checking out my BIOS today and I saw that there wasn't an option to set my CPU's multiplier. I checked everywhere in the BIOS, and the only place where I could set it was in the CPU power management and even then, the max it would go to would be 33.



It looks like some other people are reporting that they can't overclock either.

So do I just wait for a new BIOS version? Also, i'm on the latest BIOS version, 1504, was it?

You should leave the actual core multiplier at default settings. You overclock via the turbo multiplier. If you want a constant overclocked frequency, disable c1e and speed step (eist or esit i believe). though temp wise and voltage wise it's better to keep these enabled. by temp wise I mean actual heat output. I can definitely tell a major difference in the room temp. around my rig when it's always full bore.

EDIT: Now I actually looked at your first SS. I see you have no turbo ratio. Odd.... is this a K series cpu?

if yes try setting it to manual instead of XMPP and just set the main 5 timings, dram frequency and voltage to the xmpp settings. Maybe this will make the turbo ratio show up? Just a thought

Yep it's a 2500K. I've tried to manually enter the RAM settings and set the tuner mode to manual, but not go frown.gif

Your on a p8z77-v Pro correct? I'm on a p8z68-v pro, with a 2500k as well... Your BIOS has many a new options that I don't have. Are you on the most up to date bios revision?

Also, I'm going to assume you know what your doing when it comes to overclocking with these boards/chips. Maybe the z77 is different than the z68 to oc properly. But I notice you have speed step, turbo mode, and c1e disabled. p67/z68 it is generally recommended to keep these enabled. Try enabling speedstep, turbo mode, and c1e, then go back and see if you can change your turbo multiplier. Also change the actual cpu ratio back to default/auto instead of 33. If you do this and still have no turbo ratio then I'm tapped.

Thinking back to when I first started playing with my z68 bios, I can remember the turbo multi disappearing when I disabled turbo mode and speedstep. See if this doesn't fix the situation. Our boards are overclocked via the turbo frequency, not the core frequency. At least I'm pretty sure that still holds true for the z77s.
