Edit: Also, sloppy mounts are not always a bad thing. Look at all the TIM applications manufacturers use on GPUs, despite putting too much and having a sloppy application, reapplying TIM to GPUs doesn't usually net much better temps.

Aight, It turned out my TIM didnt spread properly(it did not cover the entier chip and gaps between heat pipes created two lines made of paste on the unit lol).
I did a quick cleaning with arcticlean, reapplied ZM-STG2(this time warmed up a bit and filled gaps between pipes manually) OC'd using the default settings from this guide with the following result:
375
Guess I'm good to go, eh? = D
Thanks a lot.

Hanging on a thread at 4.8oc, @ +.185v offset to bring me up to a vcore of 1.440 but with temps int 90s and the occasional hot core.
I think if I get more cooling I should be ok.
Do you guys think this two extreme and should I go back to 4.7 where it appeared stable for 8 hours under prime.
188
Well, I had to go back to 4.7. The temps was too much and core speeds began to decrease to 4.6. Does any one know why that happened ?

Hi all. My Extreme 3 Gen3 appears damaged. I've lost USB2 front panel connectors and now suddenly my sound is suddenly all distorted, sounding like its underwater. I've changed speakers, drivers, reset the CMOS, no difference. Note that I've done absolutely no new overclocking or anything else with the board. This came out of the blue. Now if someone know how to fix the sound, I'm, umm, all ears, but this seems like bad mobo juju. Also, at the same time, I've noticed that the first step of the post process is taking significantly longer. That started at the same time.

Given that the USB2 is out and now the sound, I want to RMA this board to ASRock. Someone several weeks back posted a phone number directly to ASRock. Does anyone remember that post, or know the number. They sounded remarkably user-friendly. Thank you.

Never mind, I solved it. Very weird. The sata connection to my storage drive had somehow work loose, and it was causing audio distortion. Go figure. This one is a total mystery to me. Well, at least my mobo is okay. I really really did not want to RMA, even with the bad USB2.

Heya in simple English can someone explain offset voltage to me and how an offset of +.185 equals 1.440 mathematically? My only guess is that the LLC adjusts to compensate so the core clock of 1.2v plus .185 = 1.385v + LLC adjustment somehow = 1.440?

Would it make more sense to raise offset but lower aka higher LLC for less adjustment?

Thx I use fixed voltage and just trying to comprehend all this however simple to some it may be thx!

In offset voltage mode:

Vcore = VID + offset voltage - Vdrop + VLCC

The CPU's VID is set according to what frequency you are running at, and is different for each CPU.
Typically the lower your VID is for any given frequency, the better your chip is =)
LLC is simply compensating for the Vdrop, and sometimes it over/under shoots.
Set it so it's as close to canceling Vdrop as possible. On my board LLC needed to be set to Level 1.

I am going to keep on trying to get a stable O.C until i am happy.
My heatsink is not keeping my temps very low tho and it is scaring me, i'm only a 4.5 ghz and running an intel burn test on very high right now and i'm seeing 93C
I know those are unsafe number's i have the hyper 212 evo by coolermaster.

Has anyone tried this on a ASRock z77u Pro3 board?
I don't seem to have some of the options listed in here....and I'm a complete beginner to OCing.
Some of the options missing

Unable to change Core voltage...the only options I see are AUTO or FIXED
I don't have any "level" options for LLC. I only see AUTO, 0% 50% and 100%


I have a 3570k. In case that matters.

Hey guys,

I've read the guide and most replies. Well done, your guide really helped me understand these newer mobos!

My current setup is:

CPU: i7 3770k
MOBO: Asus Maximus V Gene
Cooler: Corsair H100
Mem: Corsair 1600mhz 8gb 9-9-9-24 @15.5 volt (stock)

My cpu is currently clocked at 4.7ghz with a vcore of 1.256 (+0.05 offset). Under prime95 the system seems stable, eventhough I merely ran it for an hour. The average temps are ~74° celcius - room temperature these days is 25° celcius or more btw.

I'd like to go for 4.8ghz, but I fear I can't do this without upping the cvore to at least 1.3volt, which results in average temps of 85° celcius. Too high for my liking.

Now I've read a bit about the PLL voltage values, which are set at 1.8volt on stock. Some people say to lower these since stock values are 'always too high', others say to not touch this at all.

What does the PLL do and is it even worth lowering?

With the offset at +0.045 I had 1 fatal error on the 4th core after exactly 60 minutes of prime95. I upped the offset to 0.05 and it seemed stable.

Anyone here with the same, or similar setup which has some advice?

Thank you in advance for your help and the great guide!

Marano
