(Updated -Part II)= = Offset Mode Overclocking Starter Guide and Thread= = - Page 7

post #61 of 369
Okay so I got my SB chip 4.5Ghz stable on 1.33V, via a manual OC.

How do I set up an OC in offset mode?

Read the whole thread so I would assume that I need to set LLC to High and not Reg?

How do you calculate the offsetting voltage? and how do you go on to further refine it after BSODs?

Cheers Bro. +1 Rep to you.

So how did you know that? And do I start at .030 and then work my way up?

Hi mate, so I need Your opinion on this.
I've been running 25k in cookiecut spec stable (4.6ghz@1.368vcore manual, 1.376vid on load) now for about a year, never had much spare time for serious OC exp.
Recently noticed Your thread and started to play with amazing offset mode.
So i was going for 4.7 already knowing stable 4.6 and its vid (which already hinted on low offset) starting from the range of +0.055/+0.035.. to.. -0.005/-0.015(didn't want go lower for idle choke).
And it gave me contradicting result to Your given 4.7ghz oc sample.
At high '+' 0.055/0.035 offset was getting 1.435~1.408 vcore (cpuz)
'+'0.015 ~ 1.392
'+'0.010 ~ 1.384
'-'0.005 got 1.368 (same as 4.6) chose that for perm
'-'0.015 was giving stable 1.36 but temps jumped on some lengths to high 70
So basically is there something irregular, or some my mistakes and any other offset oc suggestions?
Thanks

great thread !

when i try offset mode , no matter how much voltage i add ,every time i'm getting error code 79

my settings are-
BLCK: 125 (using strap)
muti: 36
vcore=1.24 +( 0.04 to 0.15 using offset)
EPU: Enabled
Load Line Calibration: regular
Phase Control: Ext
CPU Current: 180%
all other things are auto

by using manual vcore i need 1.365 to p95 stable ,

I found this chart the most helpful reference of your guide:



It also helped me understand your screenshots about positive and negative offset voltages which in my opinion need some more explanation. It should be pointed out that only with a feature such as the additional turbo you can explore both positive and negative offset voltages. My mainboard seems to have no additional turbo and it took me quite some time to understand that the additional turbo is a positive offset for the VID itself which results in a higher Vcore accordingly and thus makes it possible to play with negative offsets in the end. Without that feature most people may want to opt for a positive offset voltage to achieve a decent OC and maintain idle power saving features.

Excellent thread. I just started overclocking my 2500k yesterday after finally getting an aftermarket cooler(hyper 212 single fan) after having my chip for about a year. I started with manual voltage and found stability at 4.4 ghz and 1.288 minimum vcore through monitoring, set at 1.305 in bios. I tried 4.5ghz but it would crash rather quickly and I didn't want to go higher than 1.3v as my temps seemed to start getting a bit high. I ran that on Intel Burn Test for 10 passes and 8.5 hours on Prime95 blend. I could probably lower it a notch or 2 more but I decided to start working on some offset overclocking today so that I don't have the voltage at around 1.3v constantly.

I found this thread as I was tuning my offset running Prime95 for an hour and then crashed. I upped the voltage .005 and your settings crashed it in about 5 minutes and was crashing fast until raising another .015. Now I'm up to +.025 offset and it's now done on the 1344 FFT so I will try 1792 next.

Volts at load during your test settings are 1.27-1.30 and highest temp 67 degrees. I'm pretty comfortable with that as I know Intel Burn Test will raise it into the mid to high 70's.

My settings -
Turbo Ratio: 44
PLL Overvoltage: Auto
Load-Line Calibration: Normal(0%)
VRM Frequency: 350
Phase Control: Extreme
Duty Control: Extreme
CPU Current Capability: 100%
CPU Ratio: 44
Enhanced Intel SpeedStep Technology:Enabled
Turbo Mode:Enabled
All other settings I don't remember so are probably default.

Just an update. I ran Prime95 last night and had a bsod about 4-5 hours in during blend. I added .01 more to the offset(+.035 now) and tried running it for 4 hours this morning and all seemed well. I will try to run it longer tonight, but I feel my vcore is maybe a little too high for 4.4ghz. It's running around 1.27-1.31 volts now and spikes up to 1.34 at times between loading and unloading. Idle is at .97-1.0 volts.

Should I try a higher LLC to get rid of the spikes and also adjust the CPU capability? It seemed fine running around 1.25-1.29 vcore at 100% load, but I'm thinking the spikes from 0% LLC may have caused the crashes.

I think it may become tricky to go for medium LLC with these settings. With your idle voltages of 0.97 - 1.0 V you are already close to getting BSODs at idle and light loads. Switching now to medium LLC will reduce your idle voltages even more because thanks to the higher LLC you will reduce your offset voltage accordingly. A(nd that's what you are looking for, lower load voltages.)

If you did not disable C3 and C6 so far you have some wiggle room left because disabling these states will give you an extra idle voltage of +0.04 V. That said you may get a lower load voltage for your chip at 4.4 GHz if you can opt for LLC medium and disable C3 and C6 states.

This is how I understand the whole thing so far.

^what he say
@Rampage24 ..what's with ppl and P95 4-5 hours ? lol (it doesn't mean a thing ) if you rig is stable for what you use the rig for- that is all that maters ,if you use your rig for gaming and you stable then why would you want to run higher voltage for no reason ?,on the other hand if you folding than just fold and you will find out really quick if you are "stable"...P95 was good for SB ,Ivy will lough at it (i could pass all P95,LinX,Hyper PI,etc but BF3 give me the run for my money lol (extra .030v)

EDIT; sorry for the lack of updates in this thread ..i just want more ppl involved and share their thoughts (i'm not an "expert" i just want to share my findings )
