I'm still trying to figure out how to manually lower my voltage in Offset mode. I did a CMOS clear and loaded my OC profile and it still won't budge below (or above) 1.400vcore. Super weird, maybe its trying to tell me something like leave it where it is.

Alright!!! I played around with overclocking trying to get 4.6 and 4.7 however the temps were in the mid 80's and voltage was pretty high so i decided not to push my cpu any further without a better cooler. Dont get me wrong the NH-c14 is a decent blow down cooler, and i got it for the sabertooth to bring my whole system temps down. However for just a cpu cooler its not as great as the NH-d14 with the temps i see other users have.

Anyways moving forward. I posted before and didnt read the rules so technically i wasnt able to join. However now is my chance!!! Compared to my last OC which was a 100 BLCK, 45 multi ratio, and a SET voltage at 1.35v. My current OC is running with an offset voltage setting so im not running a constant high voltage for basic web browsing and etc. BLCK at 103, and multi at 44 giving me a good 4533MHz. The voltage on load fluctuates around 1.35-1.36 and im comfortable with this for a 24/7 OC.

Here is all my proof in a screeny, however i want to mention to munaim1 that it seems my ram isnt being pushed 90% in a standard blend 12hours, so personally ill run a custom blend for personal record.

I apologize for my small resolution ill be upgrading to either a u27 or u30 soon enough


This has been a very fun experience and actually my very first OC. I just cant wait to start building more, and overclocking more as this is my new addiction. I may even watercool my system later on for performance gains!!!

Thanks to munaim1 and the forum community for wonderful information and motivation!!!

That's odd. I had the vCore set to 1.22V in the BIOS, yet it seemed to read at 1.30V-1.32V when I booted into Windows. Any ideas?

Helmut, is there a particular reason you used BCLK instead of just the multiplier to get to 4.5 GHz? The multiplier is easier to get stable with and has no risks of corrupting your data. BCLK is only really useful for suicide runs.

I just passed a 12 hr run with my 1.586 PLL. Strangely enough my peak temps rose by 1C. I think that it might be because I used the computer a little in the last hour or so, or maybe higher ambient temps.

What is your LLC at? If it is too high it could cause spikes like that.

Level 4, I forgot to say. Thing is though, it's not spiking - it was just staying constantly at 1.3-1.32V when I upped the multiplier to 41, but when I put it back down again to 40 the voltage went back to a constant 1.21V, even though both times it was set to 1.22 in the BIOS.

Are you using auto voltage? If you are it's probably overvolting it. I can't think of any way that it would go from 1.22 to 1.3 otherwise.

No particular reason, it was set at 103 for my 4.8ghz but i couldnt get temps in a comfortable level, so i bumped down my multi and left the BLCK. I could bring it back to 100 and raise to multi to 45...either way it doesnt matter.

Is it possible that the BLCK higher than 100 risk my cpu? If so i will put it back to 100

Yeah, you risk having data corrupted if you change your BCLK. Since it also OCs your ram if you change it that will effect your CPU overclock as well. It's best to just leave it at 100 and use the multiplier only.

As far as the upper voltage limit I have been told it has something to do with the VRMs. If your VRMs limit the voltage output (mines somewhere in the 1.5's) then a lower LLC will mean larger vdroop and thus a lower limit on your max voltage. Raising LLC might help by eliminating vdroop and enabling higher load voltage.s

For example if I use LLC setting 2nd lowest, I can only hit like 1.45v on load. If I bump LLC one setting higher than that, I can hit like 1.485. One higher than THAT, I can get over 1.52.

Try raising your LLC and see what happens, but be careful you don't actually end up booting at 1.5v+ unless you want that. Lower the offset first.

========

As for lowering it i dont know, that's quite weird, maybe someone else can help. At least try playing with the LLC options combined with lowering/raising the voltage.
