The Multiplier on My 1090t Keeps Dropping to X8. Why?

Hello Friends ...

I try OC my 1090t . Running 4.0GHZ at a x20 multiplier, and I noticed when I'm stress testing (Using Prime 95 Or OCCT), it will randomly drop to x8.

Cool N Quite and C1E:- Disabled .

Dont know why this is happens ? Anyone face this problem ?
 
My C2D did this for quite a while when I had it. You have to go into the BIOS and disable every single setting that is related to power savings. I'm not sure where that is on your mobo, but it shouldn't take too long to figure it out. :)
 
Disable "Cool'N'Quiet" in the BIOS. :)
 
make sure all of the power options within windows itself is set to high performance, balanced or low power profiles within the control panel can result in low CPU states
 
What are your temperatures? Since you said it happens during stress testing, this might be throttling.
 
I believe you have to turn off the Turbo thingy in the bios as well.

Turbo Core is disable .

Temp :-
Idle:-22-24c , Load :- 42-44c

Power options :- high performance
 
Anyone have solution ?
 
Does it throttle down for a second between sets or does it throttle down during the pass? What program are you using to read your cpu clock? Maybe try a different program to monitor cpu clock.

Multi drop to x8 for 1-2 sec . I use Prime 95 and OCCT for test . And for cpu clock i use CPUz.
 
after some further OC'ing and testing I think its due to the overheating over the voltage regulation circutry, or perhaps something close to this I'm not sure.

my chip @ 4ghz (200x20) and 1.5v throttled exactly the same as yours, backed it to 3800mhz and 1.45, same deal, but 3800mhz @ 1.425 and I'm golden, it'll prime indefinately at that speed without dropping.

I will try and update ...
 
I had the same issue with my AMD 965 Black Edition, and I raised the voltage up and it stopped doing it, sometime's when the voltage isnt enough for that overclock it will do as they said before and throttle down to protect itself. Now I did notice in game on Borderlands, for some reason my CPU clocked itself up, all on its own, only did it once and never has done it again.
 
My friend have gigabyte ga-880ga-ud2h and 1055t oc to 3.8ghz . without any problem.

well I know for sure my board is pretty average/low, it must be my limiting factor. its micro ATX 785G, with I think 4 CPU power phases, only a 4 pin CPU power plug, and its a DDR2 board.

vdroop is also wild on this board, I'm at 1.425v in bios, idles at 1.38v-1.4v and can droop to 1.32v-ish under stress testing.

Mine also micro ATX 880G ,4+1 phases and 4 pin power plug.

:(
 
it shouldnt be clocking down when its at 4ghz. mine didnt do that, only when i put the clock to 19x it started throttling down before i disabled c1e and CnQ

do you have EPU installed?

No.

Only sound and gfx drivers install.
 
Well, MSI and Gigabyte boards just explode or catch fire...
