With these CPUs you would need to be concerned with and deal with certain things when overclocking:
The first thing would be to download the overclocking software tools: CPU-z, HWMonitor and Prime95.
The next thing to do would be to check core and CPU temps at stock frequencies and voltages to get an idea of how much overclocking headroom you have from a temperature standpoint, which is the main limiting factor.
To check those stock condition temps: Open HWMonitor on your desktop and adjust the slider and frame so you can see the core temps section and the voltage section. Leave it open while you run the Prime95 blend test for 20 minutes. When that is done, attach a pic of the HWMonitor interface with your next post. To attach a pic, first crop and save the image to disc using Snipping Tool in Windows Accessories. Then click on the Go Advanced button at the bottom of any new post window. When the Advanced Post window appears, click on the little paperclip icon which will load the file browser and upload tool. The rest is obvious.
Next you need to be able to:
1. In bios, first disable: Cool N Quiet, Turbo, C1E and C6 and APM.
2. In Windows Control Panel Power Options configure it to High Performance.
These first two measures should disable all the "green" power saving stuff that cause erratic frequencies and voltages.
Then In bios, you will need to be able to manipulate:
1. CPU core voltage
2. CPU multiplier
3. CPUNB voltage
4. CPUNB frequency (may be expressed as a multiplier)
5. And perhaps, memory voltage
If you can locate those controls in bios you will be off to a good start and we can advise more specifically with regard to their adjustment. The terminology you encounter in the particular bios you are working on may vary somewhat from what I have used so be aware of that.
If you have a CPU with an upward unlocked multiplier, now just start increasing your CPU multiplier by .5x.
After each increase run a 20 minute Prime95 blend test to check for stability.
Always have HWMonitor open on the desktop to monitor core temps. Max stable core temp is typically 55-58c, somewhere in there.
When you first fail the 20 minute Prime blend test, increase your CPU core voltage by .025 and retest. If you still fail, add another .025 vcore. Then retest, repeating the pattern outlined. Stop adding vcore when your reach 1.5 or core temps exceed the parameters mentioned above.
Failing the Prime test can mean blue screen, spontaneous restart, lockup or one of the Prime core workers dropping out. Post back after you have added two increments of vcore or hit the mid 50's core temp wall. When you post, attach pics of HWMonitor from your last Prime95 blend run and give us a report.
The report is best decoded if it closely approximates as below.
CPU Tab in CPUz from CPUID com
Memory Tab in CPUz from CPUID com
SPD Tab in CPUz from CPUID com
And this is screen capture of HWMonitor (free version) from CPUID com
HWMonitor has been scrolled enough and large enough to show Min/Max of Voltages and includes the CPU CORE TEMPS / "package" temps fully visible.
This capture is made of HWMonitor after it has been open and running on the desktop logging Min/Max temps and voltages while Prime 95 was running Blend Mode test on all cores for at least 20 mins and then the capture of HWMonitor was made and it shows the Min/Max temps and voltages before P95 Blend was started and while running P95 Blend mode and gives much greater insight into how the system is performing without guessing.
In order to attach screenshots of INDIVIDUAL images as suggested, first crop and capture the images with Snipping Tool found in Windows Accessories or equivalent. Then click on Go Advanced, a button at the bottom of every new post window. Then click on the little paperclip tool at the top of the Advanced post window when it opens. Clicking on the paperclip tool brings up the file browser/upload tool and the rest is fairly obvious.
