OC FX-8120 BIOS settings for a stable 4500 MHz - Page 17

4.3 at a stock 1.365V should still be able to run silently with an H100.

you can see by the spelling "i have been drinking again",that's a good plan,ill try that one,i got 4200 for that voltage,might be stable at that too.

Here is my Set up, Well old Photo and I have done more with it and got a second 6870 for corssfire.



Thanks For Looking.

I had a revelation on my 8120 and CHV motherboard this morning. Everything I have read is to use the default 2600 MHz for the HT link speed or close to it as they suggest. Actually, they say that for the 8150's defaults so I just assumed the same for the 8120. Today I started a new overclock attempt with my new bios update. I was struggling to get to 4.3 GHz no matter the addition of vcore I would add. Something happened though. I did something different after failed attempts. I clicked the HT link speed down a multiplier to 2400 MHz. Instant stability! I decided to take it one step further and dropped my vcore down to 1.35v. I kept my stability. I tried 4.4 GHz at the same voltage and got one error on the AIDA64 stability test after 2 hours. I clicked HT link down another multiplier to 2200 MHz. Stable. And eventually made 4.5 Ghz stable and cool while overclocking ram and cpu/nb. No issues. All stable at 1.39 vcore load. Sounds too easy for me but makes me wonder what advantage I lose from lowering HT link with what I gain from CPU clock and cpu/nb clock and memory performance,

I don't have the pics yet as I wanted to make sure I got my full 12 hour AIDA64 stability test first. I will start it before I head to bed and add the pics of my results as soon as I can. Until then these are my final stable bios settings. Will add additional settings if requested:

CPU ratio: 22.5x
CPU Bus/PEG Freq: 200
PCIE Freq: 100
Memory Freq: 1873 MHz @ 9-10-9-24 CR1

CPU/NB Freq: 2609
HT Link Speed: 2007

CPU vcore load: 1.39375
CPU/NB voltage: 1.422

CPU LLC: Extreme
CPU/NB LLC: High
CPU Voltage Over-Current Protection: 140%
CPU/NB Voltage Over-Current Protection: 130%
VRM Over Temp Protection: Enabled
CPU Voltage Freq: Auto
CPU PWM mode: Extreme

Max CPU core temp: 52*

With this max temp I am confident I have a lot more room on my CPU clock that I can go with but right now I like 4.5 GHz as a nice round number. Can anyone tell me if the lower HT link is detrimental to my system performance? The benchmarks I have now has never been better. Any further advice is appreciated. Pics to follow.

hello please tell me a safe setup to overclock my fx 8120..i'm an amateur ...please help me!!!!
my mobo is 990fxa ud5
corsair vengeance cl9 16gb
fx 8120
please can anyone help me because i dont know what to do..

Hello. Please can anyone tell me why my fx8120 is throttling from +4Ghz to 1.8Ghz while in full load? the performance it's greatly decreased: Cinebench 11.5 results: 4.98 to 6.38.
I have OCC with the following setting in bios:

CPU: FX 8120 @ 4.290Mhz 260Mhz X 16.5
Vcore 1.3875v nb freq multip: X9.0 2340mhz cpu/nb voltage: 1.2500V HT bus speed : Auto

I Disabled : AMD C1E support, Virtualization, Cool&Quiet, amd application power management, AMD Turbo core technology, CPU active Core control, LLC enabled ( no option normal, extreme, etc, just on , off or auto) and Thermal Throttle.
I Have MB : AsRock 970 Extreme 3 P1.20 and bios : AsRock UEFI Setup Utility
8gb (2 X 4gb ) A-Data Gaming series 2000G v2.0 1.65V
AMD Hd 7950 OCC

2nd OCC via multiplicator 200 X20.0 Vcore 1.2875v-1.3500v, HT auto (2400mhz), cpu/nb voltage 1.1250 - 1.2500v

It is stable in Prime95, IBT, y-cruncher . max 45 degree celsius. I don't understand why is it throttling at 45 degree, when this cpu it's supposed to be safe under 60degree??

Please help me, i did something wrong? TNX.

Today i found why my PC in throttling, because of the CPUTIN (cpuid hardware monitor) when it reaches 65-66 degree automate throttle at 1.4GHz. Some say the cause is or a defective sensor or extreme heat on VRM's or Mosfets. What can I do? I'll try to mount a 120mm Fan to blow air to them, but i'm not confident that will work :| Any other advices? pls someone.

Hi everybody. New to Overclock and to overclocking.
Just finished my first build a week ago and now I'm trying to find out what it can do, but without any success whatsoever.
I read the thread in detail, but I´m such a noob that most of the stuff doesn't mean anything to me

Here are my system´s specs:
FX8120
ASUS M5A97 EVO (R 1.0)
16GB Kinston HyperX 1600 CL9 (it defaults to 1333 in BIOS)
GTX 550 Ti
Deppcool Gammax 400
2x1TB Seagate Barracuda 64MB 7200 (RAID 0)

I tried all the settings suggested in the starting pages of the thread, but no avail
It only makes sense since I cannot understand most of it. So far It´s been basically entering numbers in BIOS without a clue about what I'm doing.

I don't play any hardcore games or anything like that (mostly Company of Heroes), I just do some heavy-duty photo editing and graphic design, and would like to get the most out of my rig.

I tried the Multi 22.5, FSB 200, CPU Volt 1.425-145 suggested here, system boots and seems to be fine, but the second I start prime95 (blend) system freezes and i have to hard-reboot.

Everything in BIOS is set to either Auto or Standard, except for the things that need to be disabled (cool'n'quiet, APM, Turbo, EPU, CI6 and C1E. Am I missing anything).

Some guys I work with are running similar rigs at 4.4Mhz and 1866 mme (OC) with what seems to be amazing gains in speed for our line of work.. But I´d rather go back to my first garage built Mac than ask them for advice:jealoussm

Here are my system readings at 3100, evrything set to default, idle:






Any advice as to where to start to improve performance as much as possible for the kind of work I do would more than welcome

Hi I'm new to overclocking and need some help I'm also tryin to get up to 4.5ghz but something came up when I was stress testing on prime95 in a little window saying "warning SB voltage 0.000 V" what does that mean? and also what am I watchin out for on the Hwmonitor?

here is what I'm using:
Crosshair V formula
AMD FX 8120
16gb RAM vengeance corsair
Corsair H80 liquid cooler at max
Cooler master tower

Setup:

and also is there anything that I need to enable/disable?

Ratio: 18
Bus: 250
Clock: 4.515
Bios Voltage: 1.3750
Mem: 2000MHz
