Should I reverse my overclock?

post #1 of 17
Thread Starter 
Long story short

LLC Turbo 1.370vcore in bios, 1.356/1.364 in cpu-z with always a +0.010vcore rise due to turbo (stable)
LLC high 1.430vcore in bios, 1.424/1.416 in cpu-z with a droop from .424 to .416 to even 1.392 droops due to lower LLC (stable)


After changing to the gigabyte board, my chip requires alot more voltage to be stable. ive heard i should never have a rise on vcore because that is the opposite of the point of the droop which is made to keep the chip+vrm's safe. However, in order for me to have a droop i must set LLC to high which requires so much more voltage than turbo, and in turbo it only rises the +0.010 vcore in high ram usage situations/stress tests


What do I do? Do i run this chip 24/7 at 1.430v in bios with a droop always or do i run this chip at 1.370in bios with an occasional vrise due to Turbo LLC?


This overclock is killing me, been working on it for weeks!

Do what you feel comfortable with. I personally would do 1.43v constant but thats just me.

Yea overclocking can just be frustrating sometimes. Just make sure you step back and take a breath every once in a while. Some people say to never go above 1.35v some say don't go over 1.5v. It is all personaly preference. I personally think that if your temps are good you will be fine running up to 1.45ish volts.

Thanks for the support mates

The rule of thumb is to always go for a droop and never a rise? This new board makes my chip feel like a lemon! While my old crappy board made my chip seem like a stallion frown.gif

edit- since my voltage is so high im going to give 4.6 a try, it might make me feel like the high voltage is compensating for something

stuck at 4.5 with an outrageous voltage smile.gif but at least theres no rise in vcore just a constant droop for any type of load which i guess is good

i could lower my vcore and do fine for everyday usage i just dont like knowing i can not pass stress tests with lower voltages

Is there any methods to tweaking other board settings that could potentially allow me to decrease my boards vcore voltage?
Anything besides putting LLC high -> LLC turbo and having a rise on vcore

Depends.

The Gigabyte LLC levels are a bit different than low-med-high LLC from asus for example. Might be your board needs a slight adjust in PLL for example (EXTREMELY DANGEROUS TO MESS WITH PLL, READ UP BEFORE YOU CHANGE IT EITHER WAY) or up your VTT a bit.

Make your overclock slightly unstable (bootable but not really benchable for more than a few minutes) and change your setting one point at a time. PLL can be changed down before up to make it safer (STILL CHECK THIS OUT, DANGER DANGER AND SO FORTH) to see if you can stabilize.

I'm more worried about adjusting PLL and VTT on a low overclock, could you elaborate for me why adjusting PLL or VTT would allow me to lower my vcore?

Well basically PLL changes the frequency of the voltage to the cpu if i understood it correctly. I know that some people need to change it a bit to stabilize their oc. I managed to get 4,4ghz at 1.3v instead of 1.36 by just going to 1.790 instead of 1.8.

Basically Im on a gigabyte board too, and I need to use an LLC level that gives me abouts 0.05v more at idle than at load. Dont ask me why thats just how it is (spent countless hours).

Read somewhere that even reducing your PLL can stabilize your oc. So I went down from 1.36 to 1.35 and then I started BSODing after a minute of prime, lowered to 1.795 and I was stable at 1.33. Went to 1.32 and untable at prime, then a 1.79 PLL I managed to get 1.3v 4.4ghz at load, abouts 1.35 at idle.



But reading about PLL I managed to figure out thats where most overclockers burn their CPUs. Very few cpus die from just upping their Vcore. Basically on air you usually hit a dangerous heat-ceiling long before hitting your biggest OC maximum. But when youre on cooler stuff you hit a ceiling where upping vcore doesnt do much, you need to start fidgiting about with your system agent and PLL voltage. Dangerous but I havent noticed any unstability or degradation since swapping, and 4.4ghz at 1.3v is secure in my book smile.gif.


EDIT: Spelling, yup.
