Fx-8120 throttling HARD at stock settings....

post #1 of 5
Thread Starter 
okay guys, so im having an issue.
i was initially trying to overclock my cpu to 3.5 ghz but i was having some throttling issues with my chip. It would go from 3.5 all the way down to 2.8 ghz while put under full load. After noticing this, i reset to optimized defaults.
so at my default settings, i ran prime again. This time, STILL throttling from 3.1 down to 2.8... and my voltages are also jumping around too. I have no idea how long its been doing this, as ive only recently tried to overclock it. Does anyone have any insight on this issue? Is my chip defective? questionmark.gif

Anyone? I would really like some insight on this before I just go ahead and RMA both my board and chip. :/

Disable all power saving features in the bios.

hello,
go in to bios, advanced, cpu and disable everything, apm must be disabled from auto(on).
and here the "stock" overclock, its a safe voltage and found most are stable with it.
hello,

list of guides to follow here,

http://www.overclock.net/t/226939/amd-cpus-current-tech-essentials-older-tech-link-included

mine.

please monitor your temp with hwmonitor and cpu-z for reading clocks,

http://www.cpuid.com/softwares/hwmonitor.html

http://www.cpuid.com/softwares/cpu-z.html

70c of any cpu temp [cpu or core temp] is max for the FX4xxx and FX6xxx
and 61c of any cpu temp [cpu or core temp] is max for the FX8xxx,

then....

one: go in to bios, hit del at start-up till you get to a blue-grey screen before windows.

two: go to the advanced tab, then go in to cpu config and disable cool and quite and everything there on that tab.(c1e,c6 state, hpc and apm (application power management))

three: press esc and go down one to northbridge, go in there and theres one thing to go in to , there you will see ECC enabled, disable that.( happens on asus mobo's)

now for the overclock......

four: got to the ai tuner tab of bios and change it to manual from auto.

five: got to cpu ratio and change to 20 x

six: disable turbo core

seven: go to ref clock and change to 200

eight: change your ram to the right speed, 1600mhz or whatever and set your ram timings.

nine: go to cpu load line calibration and change to high (I use ultra high on my m5a99x evo and on the sabretooth i found it to be medium)

ten: go to cpu voltage change to manual and change that to 1.29v (1.325v is stock).

eleven: got to power options and go to bottom of the tab and set your fans up.

twelve: save overclock to profile.

now got to that last tab in bios save and exit.

you should now boot at 4ghz and be near stable under full load.

download cpu test programs

hyper pi is a memory test program, but it runs cooler than most cpu tests and will usually crash with os still running.
good for instantly knowing if your cpu is nearing stability.

http://www.softpedia.com/get/System/System-Info/Hyper-PI.shtml

occt is stability test program, will usually crash hardware and software if cpu/system is unstable.
good for long term oc tests.

http://www.ocbase.com/

need to test your cpu load line config with a heavy load ,use hyper pi, watch your voltage and give it a 1m test, what voltage do you get under full load?,
now move you load line up or down for increases or decreases to voltage and make it level under full load.
if you go extreme llc, lower voltage of cpu as it will climb a bit under load.

now run a full hour cpu test to see if it's stable, I used occt medium test for 2 hours.

i got a nice 4ghz stable at 1.284v at idle and under full load.

I did manage to get six core of the eight up to 4.6ghz with 1.464v showing in cpu-z.
it had heat issues after that, and my mobo is only a 6+2 vrm.

EDIT;this is my copy and paste advice for fx.

Wow, thanks man! This has really helped me get alot farther on my oc. I'm semi-stable on 4ghz at 1.296v under load. Currently one hour into occt on medium and no issues yet! *crosses fingers* even if I do fail, I know I am so close to being stable, +rep!
