Overclocking Phenom II X4

post #1 of 5
Thread Starter 
I have a MSI 790FX-GD70 and am new to overclocking and am unsure of the technological terms of my MoBo. Here is an image of my bios. Could someone please point me in the right path of what I need to change. Obviously the CPU Ratio and I believe the CPU Voltage as well. But all guides say increase voltage by .05 each time I go up on the Multiplier, but the voltage is 1.360 > 1.370 > 1.380 and so on

MSI 790FX-GD70 AM3 Cell Menu

Not sure what I need to enable or disable. Like AMD Cool'n'Quiet, Advanced Clock Calibration,Auto Overclock Technology, Multistep OC Booster etc...

Also Not sure on which Voltage to change other than CPU Voltage.. As you can see there are quite a few.

Any help would be greatly appreciated.

read the guides
read more

leave all stock

then search for your max stable multi (mine is 18=3817), test with prime, 7zip, games, etc

after that you can up vcore, nb, fsb, etc

If you haven't seen this thread http://www.overclock.net/amd-general...ing-guide.html
I'd suggest starting here. It contains a lot of very good info plus it'll give you a real good path to follow. You might want to bookmark it and refer back to it as you progress.

It always seems over whelming when first starting out, so take your time and study one area at a time, post questions as needed after that. No two chips are the same, so just asking others for their settings will not give you optimum results. As each chip has it own needs it will always vary from chip to chip. Always best to learn your chips needs for best results.

Here's some quick tips that will help get you started I hope. First, you are gonna want to disable Cool & Quiet as well as C1E and all Spread Spectrum options in the BIOS. They tend to make your overclock unstable especially as you go higher on the frequency. Second, Enable Load Line Calibration as this will help prevent vDroop when your CPU is under load.

Now you are gonna want to start with a simple Multi change to get started, try pushing your Multi up a couple notches so that your CPU is at 3.6-3.7GHz, I find that some chips can run those speeds with stock volts and some can go as high as 4.0GHz if you have a golden chip. Run Prime95 for a minimum of 10 hours but for a quick test you can try running IBT for 20 runs if either fails then you are gonna have to increase the volts.

Now as far as voltages are concerned I know there are alot of volt options in that BIOS but the ones you are gonna want to focus on are "CPU Voltage" and 'CPU-NB Voltage' and possibly later the 'DRAM Voltage". CPU-NB refers to the IMC and by overclocking this you get better performance overall than if you just increase your CPU speeds. You can increase the CPU-NB frequency to 2600 which is a good start, I was able to do that stable at 1.25v. Try to keep HT Link as close to 2000MHz as possible because it can cause instability if you go too high.

Obviously every chip is different, settings that work for one might not work for another. It is beneficial though to read as many guides as you can to gain knowledge before you get your feet wet. Start small and work your way up. Make sure you have a good aftermarket CPU cooler because stock cooling isn't gonna get you anywhere. Max CPU voltage on these chips is 1.5v for 24/7 some will say 1.55v is fine but I try to stay below the first number. Also, keep an eye on your temps, Max temp is 62° but I have read that the higher you go over 55° the CPU tends to get a bit unstable. Now I've never noticed that but good to know just in case.

Anyway, I hope this info helps you out a bit. Just start in incremental steps and you'll be fine. If you have anymore questions just ask. Good luck overclocking.
