Internal PPL overvoltage allows you to hit higher multipliers, typically you should only need that around x46 or higher, sample depended though.
 
What are your temps like, and what voltage are you using?

Can you run prime95 blend for 10 minutes and have cpuz and realtemp showing as well?

Yes, it would quite literally "smoke" it because of the heat. :whiste:

buwahahahaha... Let's be fair, they both run kinda hot..

I've been stress-testing my computer all day.

During the afternoon sun, ambient was 29-33C, my temps were up to 78C running prime 95,, but it hasn't crashed yet :twisted:

I'm using OCCT to track my temperatures. 78C in a 29-33C room running the Prime 95 small ftt.

Blend doesn't get my CPU as hot as small ftt.

I keep it hot in the room cuz I'm anemic and the doctor says I should. :|


But, I understand the point of blend for the Memory test. I think I'll do that later with IBT or just under OCCT

Are you testing heat or stability? Small ftt isn't as good as blend for stability testing.

I'd suggest testing it in some programs you actually use, of various load levels/types to get a good indication of how your LLC and voltage will respond to mixed loads.

If you have the LLC too high, you might see more voltage at high load and be stable, but in less stressful applications like gaming you might not get as much voltage and it will fail. It's good to actually test for stability in the programs you actually use since the computer will respond different and the applications will stress the chip differently as well.

Well, i guess it's just heat at this point then. But it's Prime 18 hrs stable, under small ftt. So I know the cpu is good at this voltage.


What i'm wondering about is, HOW does offset mode work

What is the basis for its offset.. Like I get the offset part, but where do you set the voltage that it offsets TO and FROM. 😳😳😳
 
SickBeast said:
It only offsets TO and FROM the stock voltage. You can't change the base voltage. Just the offset.

I heard that the stock voltage is different for every chip, is this true?? :ninja:

I also see you got an 2500k der' and a p67, which is identical to p68.

Would you mind sharing what special tweaks you made besides voltage.??
 
Ok guys, I went into "offset" voltage mode, now that I am sure the stable voltage for my 4.8ghz is 1.328 to 1.336 volts

However, in offset mode, i can only range I can set are between either 1.336 -- 1.344 or 1.320 -- 1.328

One is too low, the other is too high.

What's up with that. Can any of the other settings remedy this

Not different. You probably read about the VID. I don't know if VID applies anymore. VID was the base stock voltage under load for a CPU in the Core2 family.

Someone else would know more about it than I do in terms of whether it applies to SB/IB.

THanks, that's good news. Considering my Reported VID under coretemp changes as I use different OC settings. LOLOL😱

I have the same problem when I push for 5ghz. I can either set 1.5v or 1.57v because of the way offset voltage works in conjunction with load line calibration.

Running without an offset might fix that but I wouldn't recommend doing that. Just back down your clocks a bit; although I don't think 1.344v is too much.

Yea dude, what was up with the big advertisement with asus going on and on about DIGITAL PRECISE voltage vrm control..

Total fake out. LOLOL 😀

precision my ass :\


Do you guys think running constant 1.33v (manual) is too much wear and tear??

because if I use constant voltage instead of offset, I can pin the 1.33 volt 😎
 
From what I understand, offset method of overclocking is the best because you are able to dynamically change your vcore/clocks depending on the given load. There are instances where the CPU requires more voltage at some points in time during a given workload at the same clock frequency, hence why you see a range at the same clocks.

The problem however is that sometimes the offset voltage is too low during the ramp up (to full speed) and can make your system unstable.

Manually setting your vcore maybe fine, but your idle power numbers will be alot higher than anyone else i.e. temperature will be alot higher too. Mine goes down to ~1.025ish V during idle periods, to all the way up to 1.352V (but rarely in games).

Hi fellow 2500k-er

The weirdest things are happening to my setup.

Yesterday I couldn't get the CPU prime stable at 4.8ghz with less than 1.32 volts

Today I can run it at 1.3 volts, prime stable. (mysterious burn in)

Temperatures are the same, i didn't get magic cooling.


However, I've noticed that If I use higher voltages at the SAME 4.8ghz, my Gflops go up in Intel Burn Test.

WHAT's going on, this thing is toying with my emotions. 😱😱:'(
