i7 2600k Voltage issue @ 4.8ghz - Page 4

post #31 of 61
hmm..can't remember the asus bios so much..i had an option to set the pll overvoltage amount with the asrock..look for "turbo voltage" or something like that..

I am not quite sure what you are asking me to look for here. @schmuckley - I have nothing turned on that provides overvoltage. CPU PLL is set to auto. The problem is not me getting too little voltage, it is me getting too much.

LLC control's will help reduce the vdroop as much as possible, that doesn't mean that it'll eliminate it completely, therefore you will not get the exact same voltage as you set in the BIOS.

The aim is to reduce it as mush as possible without it spiking. Vdroop varies with mobo's, however Ultra high is genreally the best one to use on an asus 1155 mobo. Yes the voltage will probably be a little lower than what is set in the bios but it'll be as close as it should be without spiking it above. The aim is to control the voltage as much as possible, LLC can help you with that, but the voltage fluctuation is completely normal, just try and keep it lower than what you set in the BIOS.

Example:

LLC Extreme: Vcore set in BIOS - 1.35 - IDLE in windows would probably be 1.35/1.36 - LOAD would be 1.37/1.38. (not so great)

LLC Ultra high: Vcore set in BIOS: 1.35 - IDLE - 1.35/1.36 - LOAD would be 1.34/1.35

LLC High: Vcore set in BIOS: 1.35v - Idle 1.35/1.36v LOAD - 1.32/1.33.

The lower you go the higher the difference would be, that difference is called vdroop. I recommend using ultra high and increasing the vcore as you overclock, don't use LLC to compensate the vcore under load to what you need for an overclock, use the vcore in combination with a fair LLC control.

Hope that makes sense.

EDIT:

Regarding the USB, Im pretty sure it requires the FAT32 format in order for it to be recognised in the BIOS, but im not sure about that, let me have a quick look around, I'll edit the post once I find more details.

Easy way is to save UEFI screenshots to a FAT32 flash drive by pressing F12 and then uploading them so I can see what's what.

Yeah I am not using LLC for anything. I have LLC Ultra High, vcore set 1.425 bios, actual vcore is 1.408-1.416 @ load and 1.424 @ idle.

Okay so what seems to be the issue then?

The issue is that I want my idle to be as close to my LOAD as I possibly can, as that is where it's stable I see no reason to run 1.425 when ~1.41 will suffice. Is there any way to reduce my idle voltage while keeping that load voltage where it needs to be. My system runs STABLE 4hrs IBT @ 1.406 with fluctuations to 1.418.

Change to offset voltage then (Leave C1E and Speedstep enabled), here's how you can do that:

Here's how to get it to show your VID:

Click this button a few times:




You may need to put your CPU under load in order to get it to show your actual VID, but what VID do you get?

For example: I wanted 1.392V, and the difference I get goes between 0.0409 and 0.0309 because of my 1.3511-1.3611 fluctuation. So, I used +0.040V because 1.3511 + 0.040 = 1.3911. I'm also using an LLC of Ultra High, so that results in a full load voltage for me of 1.392 to 1.400V (it fluctuates).
