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..

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.

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.

I have the same setup and the same problem CPU: AMD FX-8320
Motherboard: M5A99FX Pro R2.0. My BIOS is updated and AMD overdrive also, you can see from it that multiplier settles on value 7 and when benchmark test in AMD overdrive is done multiplier sits on value 7 (1400MHZ) and benchmark results are very low.

Disabling EPU in BIOS don't help.Its clearly windows 7 problem as after reboot for short time you can see multiplier in AMD overdrive jumping between 7 and 17.5 (3500MHZ) but after a while it settles on 7 and don't jump anymore.

The only way to get rid of this is to use TurboEvo asus tool and change multiple form 17.5 (this what is shows) to e.g. 20. Then you can see multiplier jumping between 7 and 20 but not settling

Alright, so there are a two things to your issue. The second one will provide you with insight as to why your games are slow and the first one will provide you with information about CPU-Z.

1) The first one is CPU-Z may be reading the current frequency, when you have a power saving feature activated in bios (which usually is by default), i.e. C1E power state, cool 'n quiet, green settings, etc.. It will downclock the cpu when your system is idling or performing minor tasks such as web browsing, etc.. Since you are running an AMD FX processor, they have a feature called 'cool n' quiet' in your bios. Please deactivate/disable it and any other cpu power saving feature you see in your bios :) You should run CPU-Z when you are running a game and see if that changes.

2) Your HD is probably the culprit as to why your games are performing slow. Many people don't realize but mechanical hard drives degrade over time and are guaranteed to fail - it's just a matter of when. In addition to slow read speeds due to platter speed limitations and degrading hardware, your OS will dump virtual memory onto your hard drive's free space - usually around 2-5GB. What this does is when your memory fills up, it will use additional space on your hard drive as 'ram'. The problem with this is that access the data is very sloooowwwww. Also keep in mind that when you run a game or a program that is installed on your HD, it is accessing the data files from your hard drive which is limited by it's speed. SOLUTION: I highly recommend getting an SSD for your OS boot drive and installing your games on it as well. Although this can be pricey, a lot of SSD's these days are very inexpensive from the 128GB to 256GB range. You will notice an immediate improvement in loading times and game performance.

Alternative 2) Make sure you check your CPU temperatures when playing games. If you're reaching 70-80c, you CPU will protect itself by throttling down and downclocking to avoid overheating. This will produce sluggish CPU performance.

Use hwinfo64 to monitor clocks/usage while stress testing.
Cool & quiet is not at fault here - look for c6 states in bios - this is what down/up clocks depending on usage.
If you have an option disable it - high performance mode SHOULD be enabled in windows power settings.

Cool 'n quiet will be an issue if his CPU is overheating - which tends to be the main issue with cool 'n quiet.

^ this is true but I'd hold off until he actually checks his temps while running prime using either hwinfo64 or amd overdrive.
To OP

This little batch file will disable c6 states in software at low level

http://www68.zippyshare.com/v/28540088/file.html

Unzip to desktop & double click the off batch file (a black cmd window will pop up for a split second)
Then run a prime test & see if your clocks are any more stable - again use hwinfo64 or amd overdrive - cpu-z is useless as a monitoring tool.

I found another solution or workaround for this problem. It is enough to start EPU tool from asus and set it e.g. to AUTO. Then multiplier is not settling permanently on value 7 anymore, just jumps according to the current CPU load and this state remains after reboot. So it looks that it is kind of initialization fault of EPU. So for me problem is solved.

Hi, I had the 1440 thing going as well on a new build, when I see those particular numbers I tend to look for a motherboard choke switch, it was on my MSI motherboard labeled slow-mode. When switched on, the cpu is governed at 1440. Hope this helps because switching this off solved all my problems. TY

Sorry but are you serious? HDD degrade and are guaranteed to fail? Any sources for your claim? If something is guaranteed to fail it is SSD - which will wear out its cells (especially TLC). Sure they are rated pretty high but writes are finite unlike on HDD Show me example of HDD rating limiting its lifetime other then MTBF (which is not exactly limiting its lifetime anyways)
Oh and how about steady state which usually tends to be lower then new SSD performance? Isnt that degradation? By all means SSD are faster, but don't spread misinformation.
Plus if he has 8GB ram and don't have any bigger background jobs running while he is gaming it is pretty unlikely that game data will be paged out imo.
