So I contacted Asus Live Support regarding what I'm going through in this thread: http://www.overclock.net/amd-cpus/98...ghz-1090t.html

Just skip to the 4th/5th page and you'll understand what's going on.

Anyway here was our conversation:

You're now talking to Sonny from 'Motherboard ' The topic is : Safeguard?

Sonny> Thank you for contacting Asus Motherboard and Graphic Card support. My name is Sonny, how can I help you?
Luke> Hi before I tell you my problem, here are my specifications: AMD Phenom II X6 1090T 4.1GHz (249 x 16.5) 1.4 CPU voltage -> LLC Enabled -> Voltage rises to 1.467 -1.488 under load. 1.3 CPU-NB voltage NB Frequency @ 2980MHz LLC Disabled for CPU-NB M4A88TD-V EVO Motherboard Adata DDR3 1600 @ 1666mhz 9-9-9-24-33 1.71v Antec EA650 (650W) Cool N' Quiet/C1E/Turbo Core disabled The thing I'm wondering is, when I start stress testing this while monitoring everything I notice that my CPU speed will drop to 2.3Ghz for a couple of seconds and then rise back to 4.1GHz. Is there some built in safeguard in this Asus motherboard or something?
Luke> Oh that makes it hard to read :/ It didn't space it out, sorry.
Sonny> its ok how can i help ypou
Luke> Basically,
Sonny> ooverclocking your system?
Luke> Yes.
Luke> But It randomly jumps down to 2.3GHz for a short period of time(seconds)
Sonny> ok we wont be able to help with the overclocking or troubleshoot the overclocking
Luke> I'm not worried about that. I'm asking you a question about the ASUS motherboard.
Luke> Does it have a built in safeguard that would cause it to drop CPU speed?
Luke> I've read something about OCP - Over current protection.
Sonny> no there isnt
Luke> So you're telling me there is nothing on this motherboard related to OCP? I'm aware that a lot of ASUS motherboards carry this feature, but it's not something you can enable/disable.
Sonny> thats for the power on the board
Luke> So can I or can I not disable this?
Sonny> no
Luke> Ok. Thanks.

I just gave up at the end. He wasn't getting me anywhere nor answering my questions decently.

Is this while stress testing with Linpack (such as IBT or LinX)? If so, then what you're experiencing is 100% normal. This is basically what's happening:

Test #1 starts, runs, and then stops.
Test #2 starts, runs, and then stops.
Test #3 starts, runs, and then stops.
etc., etc.

So if you have it set for 5 runs, then you'll see the "drop" occur 4 times during the test.

You see, it's not like Prime95 where it's just one solid stream of processing; with Linpack, it runs for a bit, stops, and repeats over and over until it completes all of the Runs you've told it to.

Run LinX and you will see exactly what's going on.

I'll go ahead and run LinX but this also happens with Prime95.

Which test?

I'm beginning to vaguely recall that I think this happens in Prime95 too, but it's generally less noticeable because the break in between each "iteration" is much shorter.

Watch Prime95 to see if it occurs in between each "iteration".

I got to go somewhere so I'll run the tests in about an hour or so, but before I go - Could this have anything to do with it?

http://en.wikipedia.org/wiki/ACPI

I saw a few options in the bios with that in it.

 

[TwoCables]

Probably not.

I mean you helped me remember that even Prime95 does the same thing: it runs an "iteration" for a little while, then stops and starts a new one. Except that break in between is a bit shorter than the break in between each "run" in Linpack.

So I think what you're seeing is the result of the way Prime95 and Linpack work.

Intrestingly it isn't downclocking to 2.3GHz anymore.. but instead while running IBT during the first test I get a black screen with vertical lines all the way across... bumped it down to 4GHz and it just runs through the tests, although reaching high temps of 63C(Of course its about 10C lower on prime MAX)

And when it went black screen with the vertical lines across it, the computer turned off, and when I rebooted it I can't read the temps anymore? In HWMonitor it shows 0C but it does show the F degree reading.

EDIT: The F degrees just sits at 32. Did I blow my temp sensor?

Also I ran LinX and it doesn't max out my CPU at all. It utilized 2-3 cores 90% of the time and then once or twice per test it maxed out all 6 at 100% reaching I think a max of 49C for a mere seconds.
