New to overclocking (AMD X3 450, Asus M4A78LE LE, h

post #1 of 20
Thread Starter 
Hello there, just like to introduce my self first, i'm a pc repair tech but no so used to overclocking mostly deal with laptop hard issues, so yes my reason for the thread is a need help overclocking a PC, i built last year. I've used overdrive and to be honest, I don't like it at all, my motherboard is an Asus M4A78LT LE, my CPU is AMD Athlon x3 450, and using GSkill Ripjaws 8GB RAM 1333Mhz and using Artic Cooling Freezer 13 , i've been meaning to get to overclocking my PC but have not had the time, so i'm sure you will be able to help me out.
Thank you thumb.gif

Hi, that motherboard sucks for overclocking you should get a 140W TDP MB. Anyway I have a x3 455 wich did pretty close to 3.7 ghz with 4 cores on a crappy asrock nc68s uc with the stock cooler! Recently I've upgraded the mobo on my fx-8350 and got a spare a mobo for the athlon x3 wich is an asrock 990fx extreme 3 and also got the stock fx-8350 cooler and i'm pulling 3.8GHz easily never tried to push it further....but i will!

Are you going to unlock the fourth core?

Hi the Athlon II's have a locked core on it that you can try to unlock o boost performance. (If the option exists in the BIOS) That alone will give you more performance than OCing will. I was able to get my 450 stable at 3.7ghz with the unlocked core but I can't remember the voltage I used sorry. If you do unlock the core though the TDP goes up to 125 from 95 so make sure you have adequate cooling.

I would not put too much voltage into your overclock without proper mosfet cooling. Your motherboard does not have mosfet cooling so keep your overclock at a safe voltage. Do not replace the CPU heatsink thinking that you will be able to push more voltage while keeping the chip cool. This will cause mosfet failure which can be dangerous.

Your motherboard does have a core unlocker, so feel free to attempt an unlock of that 4th core. Your motherboard will not go "BOOOOOM." Don't listen to that post. Your motherboard can support the 125w that will be required, but keep an eye on your CPU temperature using realtemp or cpuid hwmonitor. Keep your temperature below 65C to be safe.

So I guess you never have an Asus M4A78LT LE before.

I did. Look through my posting history. My guidelines in my reply to the op are accurate and true. I am not misleading.

Asus M4A78LT LE can't handle it with unlock cores. The mobo will throttle the cpu under a stress load @ stock speed. The mobo is really design for 95w or lower Phenom IIx2/x3/4 and Athlon II x2/x3/x4.

EDIT
It has 3+1 phase power.

With decent cooling, he'll be safe to overclock up to 3.4 Ghz, which is the stock speed for an Athlon II X3 460.

I suggest he just keep it stock and just unlock the fourth core, more beneficial that way, plus the TDP would be around 105w so not that high.
