Im fairly new to overclocking as is most people who ask questions on here. I have been doing my research on this for the past week and can not find anything. My AMD FX 8320 is clocked thourgh bios at 4000 MHZ, ive follwed turtiols on how to overlcock without using the ASUS software my mother board comes with and i thought i did right, but when i open CPU-Z it reads only 1400 MHz. I can tell that it's not wrong because my games are really laggin and i just need some help

My Computer Specs:
CPU: AMD FX-8320
Motherboard: M5A99FX Pro R2.0
Ram: G-Skill Sniper 4x2Gb 1866
GPU: EVGA 660 SC 2gb

Your cpu is in power saving mode. Download prime 95 or linx and put a load on it then it will ramp up to full speed.. Your cpu is doing what it is supposed to. Or you can go into the bios and disable the power saving features and it will run at full speed but have full power usage at all times..

I've ran prime ninty five and it just stays there. CPUz says the core multiplier is x7 but in the bios it's at twenty.

What Bios version do you have? It has to be atleast 1006 to run a 8320, but the early bios's tended to have issues and now they have up to version 1503 now so try updating your bios if you are up for it. That could make a big difference. If it still doesn't work right after that i would download amd's overdrive sofware or amdpscheck or other software that allows the multiplier or msr tables in to be changed in windows and try manually increasing it back to where it should be. You could also go into the bios and try disabling some of the "power saving" features and see if that helps.

I'll look into the bios thanks. yeah I disabled all the power saving options so hopefully it's the bios update

Here is a link to AMD PScheck software, it will let you change your multiplier and voltage in windows along with the boost multiplier as well. It is actually in internal amd program so it lets you do some pretty neat stuff. Just install it then open it and it will show you your cpu's power states and multiplier settings. If the muliplier is set too low click flile, then settings, then click cpu settings and under pstate configuration change the fid setting (thats what the muliplier is called in amd tech speak) and it will raise the muliplier just make sure that the voltage is set high enough. The sofware has a help file if any of this doesn't make sense. This way you can get full speed out of your cpu now without messing with the bios if you rather not. If will also let you play with boost states and low power states as well as the northbridge muliplier and set different speeds for different cores. I hope this helps..

i'd really rather use the bios. I updated my bios and CPU-z and the asus software says my motherboard comes with still says it's only running at 1400MHZ. Running prime 95 and it's staying right there. Ive tweaked with the bios nothing worked then reset back to defaults and tried again and still nothing. my bios was really out of date so i figured that would do it but the clock speed is still really low

Well I dunno what to tell you then. Did you disable all power saving features and Turbo Boost? Maybe try resetting the bios to default setting and or optimized setting and see if it helps. After that I would really try that program I listed above cause it is so easy to use especially on unlocked multiplier Cpu's such as yours. You could also try AMD Overdrive to set your multiplier where it is supposed to be. Both programs can tell windows to automatically change the muliplier to what you set it to when windows loads.

This is normal and it is also a power saving feature. Just to be clear though, just because it's running at 1400Mhz currently, doesn't mean it won't or doesn't run at 4000Mhz. Your CPU cores won't run at max speed all the time.... that would be very inefficient and produce more heat.

Your bios will tell you what your CPU speed is rated or maxed at... your CPU will never run MAX during idle, only when it is required.

Disable high performace mode in bios. i have the fx 8350 overcloced to 4.4ghz. When high perfromace mode is enabled it only overclocks 2 of the 8 cores when in highe load. CPUZ only shows core number 0 so if that is the core thats not being overcloced it will show lower ghz. And use CORETEMP, it will show you all 8 core readings instead of just 1.

Have you adjusted the voltage values to be able to withstand the overclocking? Usually these cards run on modes (slow/fast) so if it isn't able to keep up with the fast mode settings that you have changed, it will always run on slow mode.
