Not sure if posted before but here goes

Vcore 1.31825
IMC 1.3
PLL 1.9
Ram 1.65

All else Auto.
What speed is this for?

Alright so I tried posting this once already but i'm sitting at 4.166GHz with 1.264v under load..

Problem is under a 30 pass IBT run these are the results i've gotten so far.

Why are the times going up over time? My temps are aroun 75C and 77C max
But for some reason throttling is kicking in and it hasn't even hit 80C.

That could be why the times are going up but why is it throttling?
Also is times going up like this a bad thing?

temp reading using a software (eg:realtemp,coretemp) can be ddifferent with the reading in the bios it depends what mobo did u use
ur Vcore i quite low for 4,16ghz but u reach 77c,what hwatsink did u use?did u apply the thermal paste correctly,and what is ur ambient temp?
and yes time increasing in IBT is bad.

Alright well i'm on water cooling with the rasa rs240 kit..
i have a asus p7p55D-E LX board
I'm pretty sure i applied it just fine. I put a drop in the center and tightened it down then took it off to make sure it spread evenly..

ambient temperatures are 73F but I also had the window open which is right next to the computer so it was taking in some rather cold air..

I got it to where IBT made it through 30 passes without failing. so i moved onto p95 and the computer restarts after running it for about 1 1/2 hours.. not really sure what to make of that.

And just on the vcore thing. I'm giving it 1.33125v in the bios, and get 1.304 idle and 1.28v under load.. those are the current settings anyways..

More vcore

Simple trial and error... What bclk are you running? Are you trying with the 21 multi?

You could try to find the highest bclk by lowering your multi and raising your bclk... Say if you know it will do 3.9 @ x.xx vcore, then lower the multi to 19 and raise the bclk to try and get to that spot.
If its unstable you know its the vtt voltage that needs to be raised, or that your chip simply hits a wall around that bclk...

its 21x198.. and this was my first stable overclock. but i only wrote down load voltage, not what it was in the bios...

but i've got the load voltage over what it was the first time i had it stable..

Maybe try lowering voltage a tad...

Or you could try and bypass 198/4.1 and try 200x21 for 4.2


What I would recommend if your having trouble with vcore vs vtt is to drop down to say 190, get 100% stable, then drop your multi and raise you bclk.
That way any instability should be from a lack of vtt voltage, or a bclk wall on the cpu....

Then you could go back to a higher multi and try again... If you know what vtt you need for 195 - 200 - 205 - 210 bclk it makes it easier...

Generally it should be:
Higher BCLK = higher vtt voltage
Higher CPU Freq = higher core voltage

So if your raising both, you would have to guess as to which needs to be raised... If you isolate by lowering the multi & cpu freq and raise the bclk you can find the correct vtt for the higher bclk...

Hope this makes sense

That makes some sense, when I first tried this I wasn't keeping hardly any info on my settings and I had most everything set on auto.. So thats why it was probably stable. I upped the VTT and i'm testing p95 again.. So far 57 minutes.. we'll see how long it makes it and go from there.. But yes that does help.

Is there a way to determine it's stable at the lower multi and higher bclk without running p95 for hours? that seems to be the biggest flaw with that plan..
