4930k and Rive BE offset vcore

systemerror · 3 Feb 2014 at 20:04

Hi 8pack

Been using your guide to ocing on a X79 and am sitting at [email protected] 1.262 in CPUZ. Still inching the vcore down. Main question is how to work out offset vcore needed. I presume when I get to my final vcore at the clock of my choice then I just minus non oc vcore from this. I.e 1.262-1.182=0.080 this is then the offset at +0.080 if not stable slowly increase would this be correct?

4.7 at those volts is pretty good. What batch number etc??

You dont need to inch volts down. Your volts are safe so leave it!!!

No the CPU dictates the volts for a given clock. Then you add or subract what Volts the CPU is applying.

Say you set 45 multi zero offset. Apply load CPU is applying 1.3v but you only need 1.2 offset would be -0.1v

Thanks for getting back to me. I am away on business at present will take a look when I get back tomorrow evening at batch number and will will also apply your adice thanks. I can get 5.0 at 1.35v which will load windows, bench and played a hour of bf4 will try get a bit more till I hit 1.45v but will not run ibt. However I am happy with 4.7 1.235v bios for 24/7 running I

Fantastic chip you have there, look after it!! And dont exceed 1.4v, 8Packs recommendations, yours is worth protecting.

Yeah I am pretty happy with it tbh

. Just need to learn how to clock memory now. Will keep under 1.4v thanks for the tip was not aware of that.

Put it this way, for me to get mine too 4.7ghz it needed 1.56v and it wasn't 100% stable, had the tuning plan on it so wasn't bothered about degradation, my replacement is now on its way!

systemerror · 5 Feb 2014 at 19:58

I took tuning plan on this but looks like unless I do something stupid I am not going to need it. When you expecting it to arrive?

Nickolp1974 · 5 Feb 2014 at 20:00

They never gave a date, but i'm hoping mid next week at the latest, got lots of new toys coming and cant test it all till i get it back

I know the feeling waiting for Evga to send me my it and waiting for OCUK to take stock of the monsoon hard line wc parts

don't forget to allow what the llc adds to the cpu,so go below +0.080,maybe +0.060 depends what llc level you use

Ok so back home, batch number from retail box is 3326B662 Costa Rica chip so gather it's week 26

hope that helps

So have implemented offset voltage. The Vid 1.201 and needs 0.95 to be stable it seems, think the reason I managed 1.235 was that I did not realise I had not changed LLC to medium it was on high. CPUZ is giving me a reading of 1.264 mostly and sometimes peaks at 1.280 for 4.7 so I am pretty happy with that now. Next question is for purely benching what would be the most voltage you would put through with LLC on high? CPU has a custom wc loop. I would like to try hit 5gig but system boots then crashes as soon as load goes on the CPu at 1.4v. Is it worth trying 125 strap before giving it anymore voltage?

Thanks for the help

Nickolp1974 · 7 Feb 2014 at 07:54

Defo try 125 strap, i have best results around 128-129 bclk.

Top voltage 1.4 yes high BLK usually helps these to get higher clocks.

Silent_Scone · 11 Feb 2014 at 09:34

Wish my chip would do 4.7 at those volts. That's a very good CPU!

My max is 4.7 @ 1.4v and 4.5 is 1.31v. And that's a 4960x lol.
