What am I doing wrong? - Overclocking AMD 8320

This is my first time overclocking and not sure if I have some settings wrong.

Setup:
GA-990FXA-UD3 Rev 4.0 with current F2 Bios
AMD FX 8320
Antek 550 LC (Corsair H50)
1866 2x4 ADATA XPG
Windows 8.1

So I went into the Bios and enabled/disabled all of the settings that could make an overclock unstable. Then set all of the frequencies and multiplexers to the stock #s. When I look into CPU-Z It shows my multi at x17.5 (what I set it to) Then its says (7-20).


Is this a setting or something in the BIOS I have wrong? Also when I ran Prime 95 It seemed like the CPU was really hot Ill test again and get the numbers. When I tested at x20 multiplier then when it started to get hot the CPU multiplier would drop down to x7.

This is what my settings looks like
CPU Ratio: 17.5
Core Performance Boost: Disabled
CPB Ratio: 20
CPU Unlock: Disabled
Cool & Quiet: Disabled
C1E Support: Disabled
SVM: Disabled
CPU core Control: Auto
Core C6 State: Disabled
HPC Mode: Enabled
APM: Disabled

And all the voltages I just went in and manually set on the Default #s

Thanks

It's showing the range the multiplier will go through in order to either save energy or get better performance. A lot of motherboards will do this so your not running full out when nothing is going on.

My first suggestion would be to avoid over clocking unless you have an after market CPU cooler installed, if you do then just slowly bump up the multiplier and run some stress test to make sure every thing is stable. Keep an eye on temps and know what is the safe range for your CPU. Remember that not all cards are created equally so if yours doesn't over clock as high as some you read about it's ok, don't fry your chip in pursuit of numbers.

Thanks for the reply. I have the Antek 550 Liquid Cooling (same thing as the Corsair H50) So I think I should be able to at least run stock/light overclock with no temp issues. I will run a Prime 95 test and get some temps in a second (they seemed hot for just a light overclock of x20), When it starts to get hot during the test the multiplier drops to x7 for split second to cool it off then will bump back up and so on. No cores failed and computer ran stable. Is this normal? I thought when you disable all of the energy settings on the BIOS then it is meant to stop it from jumping around. Or is this just a overheating problem? I didn't think the H50 would have any problem running a 8320 at 4.0GHz

Ran a test at x20 Multiplier (4.0GHz) everything else set to default #s manual and same settings as I have listed earlier in the thread.
This is what I got....is it an overheating issue? Or Bios? or Both?
I know the Thermal Limits are (CPU Core-62*C) and (CPU Socket-72*C) But not sure what one the HW monitor is reading..I usually see people who have all the 8 core *degrees listed But mine only has one *


I would Figure that the H50 Liquid Cooling could at least handle that light overclock....I will have to run another test again with all default settings and see what I get. Any input would help.

Thanks!

Sounds like overheating, I keep reading that max safe temperature for the 8320 is 62 degree celcius. The H50 cooler probably isn't any better than say the hyper 212 evo, if you look at the charts water cooling only beats air when you get into the larger radiators which is why I run the H110.

I would bring your over clock down until temps are stable and it stops throttling.

62 degree celcius < This is a fact.

Wow that's hot for that CPU My 8530 never get over 53-56c OC'D @ 4.3 all cores stressed @100% for 30 minutes WITH A CRAPPY DEEPCOOL GAMMAX 300 air cooler . That water cooler is not enough , the 212 would be your best bet , should help . What does the Core control set to auto do ?

I have just had it at stock settings and monitoring temps doing normal work and it hasn't got to hot...I will have to run a benchmark with stock settings all around soon and record the temps and let you guys know.
I still think it should be running cooler that what it is. Maybe if the stock benchmark runs hot I will reinstall the heatsink with new thermal paste...this is a prebuilt system so I can not rule out shotty install of the cooler.

I knew I was doing something wrong...played around with it today
Was able to get a stable clock of 4.5GHz at 1.3 volts....diffidently happy with this so I will prob leave it for a while. I am sure I could push it a little more before hitting 60c
