That fx should oveclock like crazy. Telling you how to do it is a different story. You should start by going over to Overclockersclub and reading the official Athlon 64 overclocking thread.It is loaded with tons of usefull info.

Yes it is alot of reading but if you comprehend any of it you will be more than able to OC that FX to it's max. Hell I didn't know that anyone that owned an FX had never overclocked it. lol

Thank you! I was having trouble finding a specific forum at Tom's Hardware.

The guys who posted after me obviously know more about this than I do. Their posts are far more helpful. So I've removed mine.

Since your FX has an unlocked multiplier this is very simple. It is also the bottleneck in your equation.

I suggest getting Orthos, a program used to test stability... also get a temperature monitoring tool, RealTemp for example. After that... (im going to keep this simple)

Head to the BIOS and try increasing the multiplier to 14x.
Reboot.
If booting fails, increase VCore voltage one notch, if no problem continue...
Open RealTemp, open Orthos and run it.

If Orthos stops: your CPU is unstable at the current settings. At this point you can lower the FSB or multiplier, or increase CPU VCore. Simply start from the top of this list again, or touch the FSB for a slight increase instead of the multiplier.

Now, if you read this next bit - no damage can occur to anything.

Warnings:
Never go above ~1.45V on the CPU. Anything below that and you're safe.
Never go above ~60C on the CPU. Anything below that and you're safe.

I would personally aim for 3Ghz on that CPU, which could be achieved with multiplier at 15x.

(Also I'm just pulling safe numbers out of my head for what I remember about socket 939, you may be able to run higher voltages if you do some reading - I don't remember everything about soc939)

I hate to rain on your parade, but, the FX55 does the OC pretty much the same as the other high end single core socket 939 athlon 64 chips did. Your lucky to get any more than 200MHz out of it and be stable. So, do not expect much more than that. Plus single core cpu = sucks for UT3 means cpu is a bottleneck.

Typically, 2.8 GHz is doable as long as you keep HT under 2000 and remember the clock also drives the memory. It's a matter of finding settings that work together.

This is pretty typical for any stock 2.4GHz;
freq = 237 (vs 200)
Vcore =1.475
Hammer = 11X (vs 12X) Multiplier
237X11=2.607GHz (vs 2.4GHz)
HT = 4X --> 237X4=948 -> X2=1896 (vs 2000)(must keep under 2000 for HT transport to be stable)
DDR = 166 --> 1:0.8 ratio --> 237X0.8=189.6 --> DDR379 (vs DDR400)

Having an unlocked multiplier just means you can increase the Hammer or multiplier instead of just decreasing it. That does not mean you can always get best performance by increasing it. But, it does mean your cpu will be 200x14=2.8GHz without increasing the base clock. So your memory and HT should be OK. You likely will need a higher Vcore, too high is bad, so do not go higher than you need. Chips are not all the same some get better OC than others, some get worse.

Agrteed with oldkawman.
2.8ghz is as far sas it'll go. Take the multi up to 14 is the easiest way -and run occt to see if it's stable.

But you can oc your graphics card with rivatuner - mine goes up to 740 core,1840 shaders , bt dont';t take you memory beyond 995
