Overclocking a AMD Athlon II X3 455 w/ a M5A78L-M LX Mobo

post #1 of 4
Thread Starter 
Hey everyone, I built my buddy a quick little budget computer with some simple components a while back. Recently he came to me asking me if it was possible to overclock his CPu. I'm no expert in the ways of overclocking but I do know my way around a few of the integral bios settings in order to do a bit of overclocking. I've been running my Phenom II 955 x4 BE at a stable 4.0ghz for quite a while now.

I'm just unsure as to the capabilities of the mobo in question. If anyone can help me out and give me a push in the right direction it would be much appreciated.

Specs:

CPU: AMD Athlon II X3 455
Mobo: M5A78L-M LX
Cooler: (The Stock Cooler of the Phenom II 955 X4 B.E.) --- Running at 29*c on startup
PSU: Diablotek DA Series 600-Watt ATX


Thanks in advance

Eh..for that RAna should be OK.Don't expect miracle overclocks.Anywhere from 3.6-4.1 could be stable.Since it's for a friend;I'd lean towards the lower/cooler options.

Thanks, yea i took a look at it and had to do a bit of research since the motherboard was a bit odd in its settings, but its all good now.

instead of overclocking, why dont you just unlock the 4th core?
Im sure the board has that option.
asus says it has core unlocker http://www.asus.com/Motherboards/M5A78LM_LX/


Now that board supports up to 95w TDP only and the Athlon 455 is already 95w at stock.
You have to make a choice, either unlock the 4th core or keep it at tricore and overclock a bit to 3.6ghz.
That should be safe for the vrms.
