Hello,

 

I currently have my FX 6300 running at 4.2Gz. To achieve this I turned up the multiplier, turned off the turbo boost option, and also turned off the cool and quiet mode. I did not adjust voltage - I just left it set to auto. Everything seems to be running good with this set up and temperatures have only reached 25 degrees Celsius during load tests. I am new to overclocking, in fact this is the first CPU that I have ever overclocked and I have some questions:

 

1: I would like to run my CPU at 4.5 or 4.7Ghz, however, when I increase the multiplier to anything above 4200Mhz I get error messages from Windows saying my computer is being shut down to prevent damage. How can I safely overclock to 4.7Ghz? What all do I need to change in BIOS?

 

Here is my PC set up:

 

Diablotek EVO case

Gigabyte 970a-UD3 motherboard

AMD FX 6300 Black Edition CPU (currently @ 4.2Ghz)

16Gb DDR3 Corsair Vengeance RAM

EVGA NVIDIA Geforce GTX 660 Superclocked

2x 500Gb Sata hard drives

Coolermaster 600w PSU

Thermaltake Contact 30 CPU cooler

2x 120mm case intake fans

4x 120mm case exhaust fans

 

Thank you,

The errors you get in windows are because your overclock is unstable above 4.2 Ghz. As you go above, increase your voltage by small increments like .005 volts. Download a utility such as Prime95 and run that in windows for 20 minutes, it will stress your cpu. If during the test it displays errors, or the PC locks up. Restart, up your voltage by another .005 and retest, and do this until you can run the test without problems. Ideally you should run the test for like 12 hours for solid stabillity. You should do all this everytime you increase the OC.

 

Be warned though, before doing this, check what the max safe voltage is for your cpu, dont go above that. Also monitor you cpu temps while using prime95 and make sure they dont go above the max recommended for your cpu (you can find that info to online.)

This is great information Alex. I will download Prime95 and also check the voltage / temp specs of my CPU before I make any further changes. I am also using CPUZ and HWMonitor when I run tests. Are these programs good or do you recommend something different?

 

Thank you,

I actually use those 2 exact programs, CPUZ, HWM, as well and they work great. There are a number of different stress programs out there but Prime95 is the only one I've used and it does the job well. The voltage value you want to change is Core voltage (Vcore). You will at some point hit a wall, as in you will have to increase voltage by a lot, for very little MHz increase, just FYI. Good luck!

Hi Alex -

I am now running at 4.5Ghz B)

 

I had to increase the CPU core voltage .125 (increments of .025)

 

After running Prime95 for 30 minutes the max temp reached was 38 degrees. All of the cores stayed stable and never dropped and there were no errors reported either.

 

The only thing I noticed is that when I run the full stress test the core speed sometimes drops for a second to 3020Mhz and then goes right back to 4580Mhz. When this happens I also notice voltages changing but all of the cores remain online and still no errors. I checked this while under normal operation and while running FSX and the speed core speed stays constant at 4580Mhz - never drops. Is this normal during stress testing or no?

 

Thanks again for the great help!

Can anybody tell me the blck settings and the ht link setting?.... i'm new to overclock and i have nearly this exact setup. minus the aftermarket cooling.... my core speed is at 4.3 but my voltage seems to keep fluctuating in cpu-z. does anybody have any advice on how to approach this?
