Somebody quickly help me setup my offset?

post #1 of 8
Thread Starter 
Right, ive got my 4.8ghz oc stable at 1.425v, but i cant stand the fact its a constant voltage. How do i set my offset so that the voltage only rises when under load? I really dont like it at 1.425v 24/7.

Thanks, i would screenshot but every time i try and screenshot it just says please select flash drive, with no drives there...

Rep to those that can help me quickly. Thanks

you need Flash stick in FAT32 (F12 in bios)
i assume 1.425v in bios and what you see in CPU-Z (voltage fluctuations)
P.S. it takes time to set up offset correctly

1.408-1.416-1.424-1.432

it mainly hovers at 1.408 though it seems. no it doesnt tongue.gif

I figured it would be a process that needs to be precise, its a big ask but could you help me get it right?

if you positivel your voltage posted above is stable,
try this ;
Ai Tweaker
Ai Overclock Tuner:Manual
BLCK/PCIE Frequency:100
By Per Core:48
Internal PLL Voltage:enable (if you can run it disable then disable it)
EPU Power Saving MODE:disable

Ai Tweaker\ CPU Power Management >
CPU Ratio:Auto
Enhanced Intel SpeedStep Technology:enable
Turbo Mode:enable

Load-Line Calibration:High
VRM Frequency:350
VRM Fixed Frequency Mode:Manual
Phase Control :Extreme
Duty Control:Extreme
CPU Current Capability: start 130% (you can lower it later-i can run LLC high @5.0 /100% capability )
CPU Voltage:Offset
CPU Offset Voltage:+ .090 (start @+090-run P95 and observe CPU-Z voltage /adjust your offset value in bios until you mach your manual/fixed voltage or slightly higher )
CPU Spread Spectrum:disable

C1E:Enable
C3 :Disable ( c3/c6-some can run it enabled some can't)
C6 :Disable
P.S. watch you Idle voltage,if you starve you CPU under idle you may get BSOD or freeze,you can adjust this with
+/- offset value or additional turbo voltage/LLC level=> whatever works best for you and your CPU

Hey I'm using offset, and it's great to have idle voltages at 0.960-0.984v. I also have C-states and Speedstep enabled, so on many occasions for small tasks my CPU gets to 2.8Ghz at some ~1.1v, so that's an additional bonus.

Anyway, I think you'll find it easy to setup.

Just disable LLC (so vdroop can function normally - don't worry you are still going to be stable, but you'll also save your CPU from massive voltage spikes), enable all C-states, Speedstep and power saving features, then configure your multiplier and finally start off with a higher than needed positive offset, and lower it by 0.005 or 0.010 increments on each restart until you finally get a BSOD while booting into Windows.

Once that happens, I find adding 0.010v-0.015v in the offset helps me to get a stable OC. You can verify that by benchmarking in Prime95.

Since you are aiming for 4.8Ghz, you could start with a positive offset of ~0.085v (maybe 0.090v) and see how it goes. If I remember correctly, at 4.7Ghz I could get it stable at 0.050v or 0.055v.

Finally, I only do a few hours in Prime95 and not 12 or 24 hours as some recommend. The thing is I don't fold with my PC, and most of my intensive tasks only need 1-20 minutes at most, meaning in my case there's no point in having a 24 hour full-load stable overclock. So I'm pretty sure that for 95% of the users a 2-3 hour Prime95 run is going to be enough in most everyday situations. Plus you're going to be able to get stable with an even lower voltage biggrin.gif

Thanks guys, ive got my offset at 0.090+ and everything seems stable and fine i ran prime last night for 10 hours, no errors ran smoothly, then ran 10 loops of IBT. Still, no errors!

388
309

Just like to say big thanks to coolhandluke for the settings, they were a massive help and without even needing to add my own personal tweak to those settings, they worked fine as you posted them on here. Thank you very, very much for helping me get my desired bombproof stable overclock!

Also, thanks Sew800. I will get round to tweaking the settings at some point according to what you told me smile.gif but at the minute, it all seems to be working fine. Ill tinker with it if i need to in the future

THANKS rolleyes.gif
