show your sandy bridge 24/7 clocks and volts

i think someone from asus said high is enough for most overclockers, so i'll just set it to that


edit: i have set it to high with an offset of 0.05

load is 1.272 -1.28 in prime

i'll prime it tomorrow properly, just switched prime on for a minute to see the volts, this is for 4.2 ghz

Aye high is enough for every day usage overclocks.
What Cpu you using & what speed/voltage?



If its a decent chip you should be able to get that voltage down a lot more for 4.2, unless its a 2600k with HT enabled that is.
I can get mine down to 1.128v load @ 4.2Ghz = Offset -0.185v + LLC Medium

yeah it's an i5 2500k

perhaps i should look at 1.2v to start with and work down then?

You could probably overclock straight to 4.5 - 4.6 with that much Vcore, doesn't take long to find out using the Ai Suite.
I tested 4.2Ghz a while ago out of curiosity, only took like 10 mins to find out where it became unstable @ around 1.1v

Thanks, this has given me inspiration to try and at least reduce the Vcore for now, maybe once I get a better understanding of the ASUS settings I might feel more confident in upping the multiplier knowing that i'm not going to overvolt the cpu.

I had a + Auto offset so I changed that to - and set the offset to 0.055 (a good starting point I thought). It's been quite happy in Prime for a while now but i'll leave it going all day and see what happens.



I tried 0.06 offset but it BS'd in a couple of minutes. Any higher than 0.06 turns the digits red in the bios even though it's within the allowed range (?). I still have lots to learn about the ASUS bios :o

Don't worry about the colour m8 unless your going +Offset and pumping too many volts into it.
If going from -0.055 to -0.060 caused a BSOD then it looks like your at the limit of how low the vcore will go on that chip :(

i have an asus z68 board too

what llc do you use? and other settings?

at 4.5 on 1.32 a worker stopped after bout 45 mins, whats a good safe voltage for these chips?

I replied to you last night with a couple of posts about what LLC + Offset I use with diff overclocks.

There's a big debate over what's safe 24/7 voltage with Sandy Bridge, truth is no one really knows for sure.
If you want to be ultra safe then don't go above 1.35v

I use LLC level 5 and set bios vcore 1.32v for 4.5Ghz also use 4.0Ghz LLC 5 1.27v, 4.2GHz LLC 5 1.28v, 4.4GHz LLC 5 1.30v, 4.5GHz & 4.6GHz LLC 5 1.32v and 4.7GHz & 4.8GHz LLC 5 1.35v

on this asus board with offeset you can't set the voltage, only the offset of which you want to change the boards voltage choice by

unless i'm missing something
 
i think the only way is to see what the board sets it to automaticaly then use the + or - offest to bring it down or up by how much you want

this is for my asus anyway

e.g, you set the turbo ratio to 45
boot into windows
start prime briefly, and see what volts it is at
then use the offset to put in a value you want to raise or lower it by
so if the board set it to 1.42, you have to use a negative offset of 0.020
 
here's my latest, wanna get as low a stable 4.2 as poss before trying higher, it's hovering between 1.224 and 1.232

seems like quite a big voltage bump is needed for 4.4

gonna test it for a 8hr stretch when i find what i think is it's low limit

this is where i got with initial quick stability testing, going to lower volts next, should i be worried about idle voltage with offset? it's below 0.900 now

ahhhh i thought it was something like that what a load of messing about.

will give it a try when i have 3 days spare lol

That's what I'm thinking although it seems you can adjust it in AI Suite:


(idling)

I kept the same offset but tried dropping the 'CPU Voltage' setting above down a bit and it BS'd again (code 124 again). I don't know what the value relates to - it's neither the idle or load voltage.

And I only just realised you can adjust the multiplier in there too. :rolleyes:

I'm not going any lower now, it's been fine on Prime since my morning post so I think that unless it's one of the auxiliary voltages that needs changing then this is my chip's limit.
 
Would be good to see some Prime Blend screenshots as Lynx (from my experience) was pretty useless at testing stability with Sandy bridge. Here is mine for what it's worth...
