you mean xtremeoverclocking? lol. Turn LLC on to level 5 or level 4.

Oops! No, haha I was waay off... extremesystems.org.

I finally loaded EasyTune6 which I was reluctant to do but it appears the core speed is constantly fluctuating with desktop activity and it shows this. Other programs do not show the changing core speed. This is what I was after! So the CPU IS throttling, other programs just do not illustrate this fact.

Yeah, the voltage @4.4 and 4.5 are shown as 1.3661v in Coretemp. HWiNFO32 shows what the bios is set to, 1.38v though the "current" value changes from 1.28v to 1.68v when the processor speed rises so there is some droop there. I'd imagine @4.5 it was just not enough to handle the speed.

Yeah, looking at the chart you had posted over at extremesystems.org, LLC 5 or 6 looks to be ideal.

Will turning on LLC affect the other EIST or C1E functions or will it just smooth out vdroop?

Also, instead of leaving everything at AUTO, can I adjust numerous settings and then after I find a minimum stable load voltage at a particular clock speed, THEN turn back on C1E, EIST, C3/C6 and the processor will go back to regulating core speed again?

1.68v ??

First off it shouldn't goto 1.68v on its own, SVID only works upto 1.52v and its hard to get it there, that must be a typo?

Anyways you can turn them back on, but they also try to regulate votlage so I don't like them.

Man I am the worst typer.

1.28 --> 1.38

(you should have suspected a typo! (Sin did tongue.gif)) j/k eek.gif

If its turning down the processor clock, its turning down the voltage and thus power usage. Does this affect OC voltage stability? It would seem that if you have a voltage set for a certain OC and also using LLC that it will turn down speed and voltage but when it goes up under load it should run at your "set" settings.

What's your experience with this and have you measured with these types of settings under load?

(from reading posts at extremesystems.org, I know you have done a lot of testing and have a multimeter, Sin, hehe)

it really shouldn't affect it, but it does many times. That is why most OCers do not use it.

So then you are saying that setting VCore and LLC->5/6 to a manual setting will be OK to use with Turbo mode and other "auto" settings?

Or - Can I set JUST the LLC 5/6 and it will stabilize the "Auto" VCore setting?

I'm not an extreme overclocker, don't run benchmarks to get the highest possible scores (though I understand the competitive nature of this and love it).

I just want to run 4.5Ghz all the time with the lowest possible, stable voltage, AND have the processor turn itself down when not in use.

As I said before its @4.4 now just changing the Turbo Multi's and prime stable (30min) and I just need a way to stabilize the 4.5 auto vcore. Will enabling LLC 5/6 do this with Auto Voltage set?

After I get to 4.5 I'll prime test for 12-24hrs.

you can do it both ways, you can leave them on and use LLC, it will just help the voltage stay higher so that you aren't unstable.

Definitely a bios bug of some sort.

I tried two things:

1) Change Turbo Mult to 45x on all 4 cores only + Enable LLC 5/6 (Tried both)
Computer reboots and then goes in to infinite reboot loop.

2) Changed CPU Mult to 45x AND Turbo Mult to 45x + Enable LLC 5/6
Computer reboots and then goes in to infinite reboot loop.

Also, this bios has NOT worked out the infinite reboot loop for some configs as the above shows and ALSO, when it goes in to this reboot loop I can shut off my power supply or unplug it (tried both), press reset CMOS button either briefly or hold it for 10sec and it does nothing. Plug back in power, turn on power supply, boot board... it gets to the post beep and readout on the board shows the wonderful 4E code and then it reboots again and goes in back in to the reboot loop.

Only way I've found out of it is to pop the battery, then clear CMOS, then put the battery back in, turn on power and reboot and then it reboots fine with CMOS cleared.

This has to be the bios as I know the infinite reboot loop has for some reason plagued this board. Pain in the ass to pull both my vid cards when it happens. I'm really glad my vid cards aren't watercooled too or it would be a major PITA.

In any case... So I set 45x CPU mult, Disabled Turbo, set VCore manually, set LLC 5, save and exit. Board doesn't even power down and then back on like normal. It just reboots, shows the bios screen, posts, and in to windows with no issues like you reset it.

I'm probably going to stick to these settings provided they're prime stable until a couple bios updates come out because with CMOS reset not working, its a major PITA.

please enable CPU PLL Overvoltage, then try, if that doesn't work, leave CPU PLL overvoltage on and take vcore to 1.4v.


You have a not so great CPU>

here is the thing with infinite boot loop, it doesn't just happen, the system has to be unstable for it to happen smile.giffrown.gif
