I messed around with it at 4.5ghz 1.22 vcore without changing any other settings in bios but got whea errors in prime, so I decided to clear cmos and start fresh.
I have a few questions pertaining to some of the bios settings recommended by the guide.
-Can I set my AI Overclock Tuner to X.M.P ? I tested stock settings with XMP, my ram at 2133 9-11-10-28 1.65v, ran prime without issue for 8 hours.
-Why does the guide say to input the overclock in turbo settings and in CPU power management? Isn't that redundant?
-Is PLL Overvoltage really necessary for 4.5 ghz ? Have you guys had any experience with stability at 4.5 with that setting on vs off?
-Why is it wrong to change voltage with offset mode? As far as I can tell using this over manual shouldn't influence stability at all since it doesn't cause fluctuations in voltage.
-Since I have DDR3 2133 at 1.65v and the CPU overclock is relatively high wouldn't leaving CPU PLL voltage the way it is be better than undervolting?
- Is the point of LLC to not have overly high voltages when the processor isn't loaded? Doesn't LLC at Ultra basically override vdroop? I thought vdroop was supposed to make your processor last longer. Can I reduce LLC if load voltages are near the value I want them to be?
-Finally why do you disable BCLK recovery? Isn't it just a safety feature if somehow the base clock frequency gets messed up? What is the Xtreme Tweaking setting in my bios and should I enable it?
I realize this is a lot of questions. I've been reading all day yesterday and couldn't find answers to these questions.
1. OC tuner is AUTO OC - don't use that -> XMP is perfectly fine, but I found it better on manual, as I could set what I wanted.
2. PLL: It really depends - personally it was better with it enabled
3. As finding your perfect voltage via offset is extremely time consuming and hard. You might think it might be "+" when in fact it is a negative "-" offset
4. I wouldn't undervolt it - and yes PLL depends on case by case basis
5. If you reduce LLC you'll ahve to increase voltage. Basically vdroop will be dropping your voltage, and at high loads, means that your 1.27v for example, will be dropping to 1.22v and thus you';ll be unstable and probably BSOD - 50%+ LLC counters it - sometimes as noted in this thread, a bit too much - long story short, you have to have your PC stay on the same voltage you put in the BIOS, when on FULL LOAD (ignore to some extent idle voltage)
6. I can't answer that - but There is info I got when researching of it at the time.
The MOST IMPORTANT thing in OC'ing is your temperatures - more than anything. So please make sure you are monitoring your PC before leaving it on its own P95'ing
Hope this helps!
