AMD FX 8120 on a 990FXA-GD65 (MS-7640) motherboard overclocking.

post #1 of 3
Thread Starter 
first of all this is my full set up

AMD FX-8120 X8 3100MHZ 16MB 125W AM3+

MSI 990FXA-GD65 V2 AM3+ 140 Watt

Kingston 8GB 1600MHz 9-9-9 DDR3 XMP HyperX Red (2, 4GB sticks)

Cooler Master Seidon 120M CPU Liquid cooling

Sapphire Radeon HD 7850 1GB DDR5 PCIe

ULTRA LSP750 750W ATX POWER SUPPLY

Toshiba 1TB 7200rpm 3.5" SATA (storage)

Hitachi 1TB 7200rpm (storage)

OCZ-agility3 60gb SSD (operating system)

ULTRA GLADIATOR BLACK MID-TOWER CASE V2 (modded the case to mount the radiator in a different location will post pic's if you wanna see)

all i want to do is get the CPU up to a stable 4ghz and i cant find any info on how to do this. so far i have it running stable at 3.710GHz running prime 95 (for about 6 hrs) but i cant go higher without a system freeze. please any help is very much appreciated.

hello,

list of guides to follow here,

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

please read a guide to understand how your bios setting work.

I like this one the most,

http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

if you do understand then its easy as this....Disclaimer

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

if you follow the advice below, you do this at your own risk and at risk, your personal computer is all your own property and problem, and is not 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 configuration 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.
