As simple as raising multiplier in BIOS for FX-4100 overclock?

post #1 of 15
Thread Starter 
Hi, I just received the FX-4100, ASRock 970 Extreme3, and G.Skill Ripjaws X Series 8GB 1600. According to this article, http://www.legitreviews.com/article/1766/16/ I could just raise the multiplier in the BIOS with the stock cooler and not change anything else. This will bring me to ~4.6 GHz, which is really impressive. Should I try this? I have never overclocked before and I am using the stock cooler. I want this CPU to be stable and last a long time so I might go only for 4.0 GHz

Wouldnt hurt to try, just make sure your temps are within reason.

Should be fine up to 4ghz on stock voltage, 4.6ghz will proably need the vcore to be upped a little bit.
Also make sure you disable APM or it will keep throttling its self back down to stock speed.

And lastly run prime64 for atleast half a hour and watch the temptures with hardware monitor.

What is APM? Also what is a normal temperature?

AMD Power management,
It limits the CPU to its advertised wattage.
So if you have a 95w cpu it will be keeping it at that power useage which is hard for them to do even at stock speeds so you lose performance but its making very quick adjustments to the multiplier to drop the clocks right down.
The higher you overclock it the longer it will drop the clocks down.

Max temp for 4100 is 70c so keep it under that.

Your board will need a bios update first and foremost. After that disable APM, Thermal Throttling, and C6 in BIOS. Set CPU multiplier to 23 and CPU voltage to 1.4v-1.475v. Set CPU_NB speed to 2400 and CPU_NB voltage to 1.25v-1.275v.

Start at the low end of these ranges and test with OCCT (CPU Test, small data set). If it gives you errors, bump the voltages up one notch. If moving a particular voltage up doesnt help at all, set it back down and try the other.

Also, get Core-Temp and dont let it get over 70c. If you see it getting over 60, stop what youre doing move back to lower clock speeds. You will need a HSF that is better than stock, regardless of what some of the reviews state. (most didnt disable APM and the chip was throttling itself most of the time, which totally negates your overclock.)

He's on stock cooler.

Thanks, so basically I just raise the multiplier and disable APM, thermal throttling, and C6?

Yup, just make sure that temps stay below ~60c. Otherwise you will probably have stability issues from my experience. 4.4Ghz is probably a safer bet with the stock HSF. voltage should be 1.375-1.400 for that.

Stock cooling will hurt your CPU. You can get this CPU cooler (it's cheap and great for his value). http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
