post #8211 of 19540
What are the standard vcore increments? With my biostar board they seem to be .012 V

Is there any point to changing vccin voltage or running a higher llc setting for the vccin?

I know that vccin is supposed to be .4V-.6V above the vcore voltage.

A certain VRIN level is required for stability, and you need LLC to stop it drooping particularly for higher overclock or i7 where you have more power draw

Thanks,

Remember, it's about one variable at a time.

I'm new to overclocking, trying to get the temp lower, at 4.3ghz i get 35-40 in idle witch is very high imo, but i'm thinking that i just put the thermal paste on CPU (didnt diddle it yet tho). hoping it will lower down at least 5 degrees in a few days.

ps. is diddle really working as people say ? i don't know if the guys i bought the CPU from will still offer me warranty if i do it. and i want to be sure...

You looking to get charted? I'll chart you.

The 28.3 version is supposed to stress Haswell more. I will do some more testing and see if it crashes my x48 again.

I'm not real concerned about it, but I know some of you guys like to be able to pass any kind of stress tests. biggrin.gif

I've tested the temps of 30.1. I'm assuming 30.1 was a beta number and 28.3 is supposed to be newer than 30.1. Check out the temp chart on first page under stressing section. I believe prime 30.1 is hotter than IBT.

No adaptive on IBT? You should. Funny things will happen. :hannibals

I'm running 1.42v 24/7, more than most people because I have it on normally for gaming, I have it on under 100% load for chess at nights.

I'm sure there is a value, but the number I don't know. If by max you mean max safe number, there's really only one way to tell: To do a test and kill 1-10 cpus by running very high Vrin values. And I'm not too keen on doing that right now.

Maybe, but you should always have high enough vrin to not have issues like that in the first place (otherwise you see weird stuff and instability)

as a template, something like (with llc turbo)

~1.2vcore, 1.8vrin

1.3vcore, 1.95vrin

more or less depending on if you need or not. That's a bit high for safety

Where did you find a Prime 95 30.1? I confess I never heard of it.....link?
But for sure the whole 28.x series was much hotter than any of the 27.x series....I have to pile on Vrin + Vcore to pass 28.3 small fft's.

It's oddly difficult to track beta versions of Prime95. It's even harder to find original posts. Maybe I saw it wrong, it was 28.1 not 30.1. 

Here's a post:

 

http://91.151.218.11/showthread.php?p=21831990

 

Prime 28s being 11C hotter than 27.9 (both small ffts) in my test, 28s being hotter than IBT.

Generally you can find most programs in the TT Gigabyte forum...Stasio searches out all the latest programs and posts them up.

But yeah, 28.3 is hotter than 28.1 for sure. biggrin.gif

Does LLC stand for CPU Line Load Calibration? Mine was set to Level 1 on my BIOS. I have level 1-5. Right now I set it to Level 3 and dropped Vrin to 1.90V. I am about to test out my system with XTU first then x264 20-30passes.

Should I start off at Level 3 or go all the way to Level 5?

My load-line is at 8 the farthest it will go, maybe I should scale it back, I'm getting BSOD a lot lately. and my core ratio is 42, not very high, but the BLCK at 111 which effectively ups my core to 4664 or something effectively puts it right back at 4.7 GHz.

My current capability is at 140% the highest IT will go
