Using iGPU, higher vcore using same offsets then before?

post #1 of 2
Thread Starter 
Hey guys, first off I am using offsets.

So I am using windows 8, checked what my max vcore was under prime when my 680 GTX was installed, max according to hwinfo was 1.280, exactly what it should be when I tested in windows 7 and my previous windows 8 install.

After selling my 680 and waiting for my new card to arrive I tested again, only thing that changed was I installed a bunch of windows updates, however I had these installed in a previous install aswell.

Now I hit 1.288v in prime, its almost immediate, I am using the same offsets, I am guessing the CPU wants more vcore so the VID is higher meaning my offsets ( + 0.10v ) allow it to hit 1.288v?

Update :
Okay, update, I am even more confused then before.
Let me sum things up again


Wake up, check hwinfo, says I hit 1.288v max at somepoint last night while running prime95 blend

Run Prime95 Large FFTs, hits 1.288v and flucates from 1.280-1.288 with drops to 1.272, shut it down after a minute.

Reformat

Bios Flash

Load Profile up ( Saved to USB)

Try again, Large FFTs, hits 1.288v again as above

Go into bios, try seeing what 0.005v and -0.005v get compared to their normal values, they test fine.

Set OC back to 0.010 (did not reload the profile, simply set it back to 0.010)

Hits 1.280v, Normal.

Go back to bios, reload profile

Hits 1.288v the first time I run prime, cannot replicate again.

Load Defaults, See a bunch of iGPU offset options and other options that do not show when I use my saved profile ( Was created before I sold my GPU and ran off iGPU )

Recreate the same settings as my old profile but leave all iGPU options as default

Hit 1.28v


My question is WHY is it doing this, I am just really confused as to whats going on, its not easy to replicate even when using the old profile, sometimes it does it sometimes it doesn't.
