Close that window, you don't need change anything in Options -> CPU.

I know it isn't a good thing but I was just checking.

Also I just BSOD trying to run prime95 what should I do? increase voltage?

EDIT: I bumped it up to 1.315v for a multi of 45?

Where is the small FFTS option?

Well you don't want to just increase voltage blindly until you get 45, try backing down your clock and see what clock is stable at that particular voltage.

Once you've found a stable clock at your 1.315v then bump clock up by the next tier - 44 to 45 etc. If it bsods then increase voltage but only by small increments.

Using the above image from the thread I linked you earlier you can see you don't want to exceed that max intel spec VID, or VCORE which is 1.55V. Personally I won't even run that for a daily clock as it'll wear your CPU prematurely imo.

If follow my instructions you should see the option, it was even in the screen shot you posted.

It's under options -> torture test

I just BSOD after trying to run with 1.315v at a 45 multi again?

What should I do?

I just edited my post, but didn't finish in time before you read it.

Quote:
Load Line Calibration or Vdroop control is a setting that eliminates/reduces processor voltage droop under load and in many extreme cases many reverse voltage droop. Voltage droop is there so that under load conditions where current (amperage) is increased the processor stays within TDP (Thermal Design Power). There is also vdrop which is implemented by the motherboard manufacturer, vdrop is there and it drops every voltage on the board from what is set in BIOS, no matter the load. LLC can reverse Vdroop and Vdrop in many cases.

You might need to set your LLC to mid level to help with the ramp up of load, your ASUS board should have a LLC or Load Line setting in the BIOS, find whatever option is middle and set that.

Doing this will most likely increase your temps so you'll have to find a setting combination that'll give the results you want, you may be able to lower the LLC setting once you tweak your clock more.

Alright thanks I will lower the multi down and keep the voltage at 1.315v to see which is acceptable at that voltage. If my cpu wont accept 4.5Ghz at 1.315v how much should I increase it via intervals?

Yeah I saw that, same dw about my post about BSOD'ing

I will check if the LLC is on that when this ffts thingo is done, I'm at test 7 and the max temp is at 64 degres Celsius maximum the rest are like 61 and 57

EDIT: I dropped the multi down to 37 and I will increase it to 40 then 42 then 44 then 45 and then thats it smile.gif hopefully it does it at a stable voltage!

So the max volt is 1.55v?

Also, what would you say the max voltage for a 4.5Ghz should be?

Thank you for your help so far biggrin.gif

I stopped this instance of small FFTS at a 37 multi and only got up to 64C on one core at 1.315v

I am upping the multi to 40.

Well Prime 95 will run longer than you'll ever want to wait lol, just stop if after 10-15 minutes, for a true stability run I'd run it for at least 30mins but longer the better, extremists will run it overnight or for 24hrs I personally don't do this.

Max is 1.55v as stated by Intel specs, unless you're using liquid nitrogen or dry ice I wouldn't exceed that biggrin.gif

There isn't a max voltage per clock necessarily as every chip is different, I don't have my Sandy Bridge rig fired up atm so I can't remember where my 2600k was at as I ran 4.5GHz with it, although it has HT which affects overclocking so it'd probably need more voltage than your chip.

I would say for sure you shouldn't need more than 1.4v to reach 4.5GHz on that chip, another thing you could track is how much voltage per 100MHz you have to add.

For example:

1) you only have to add .1v to go from 40 to 42
2) you have to add .3v to go from 42 to 43

Scenario 2 should tell you that you probably have reached the max overclocking effeciency for your chip/cooling capabilities and that you probably want to stay around 42.

Options for LLC are:

AUTO
Regular 0%
Medium 25%
High 50%
Ultra High 75%
Extreme 100%

I set it on ultra high already.

Should I set it to high?

EDIT: Multi of 42 still at 1.315v max temp is 68C

So are these FFTS representative of gaming load or is it more?
