s939 opteron 180 and a8n-la overclocking

post #1 of 7
Thread Starter 
My brother recently bought an AMD 939 system with a single core 3800+ and an NVIDIA 6150 SE. He is upset that the computer barely gets more FPS than his laptop which is also trash. He's been playing games at 10 FPS for a long time, so long he's actually gotten used to it completely which is kinda odd.

The motherboard in the AMD system he bought is an Asus A8N-LE OEM board, the system's RAM was recently expanded so it has 2GB DDR400 on it. I'm going to be installing a fresh copy of Windows XP Professional 32-bit on it soon.

Okay so here's the deal, I want to upgrade it a bit so he can play even new games on at least the lowest settings at at least 30FPS min on 720P, he's going to be using his flatscreen 32" as a monitor.

I bought an Opteron 180 2.4GHz dual-core, I am wondering how well I can overclock this through Windows since the BIOS is obviously locked. I'm planning to pair up the CPU with a 9600GT or 8800GT 512MB. The entire upgrade in all will cost about $60 and provide a significant performance improvement.

So how much can I get out of an Opty 180 just Oc'ing in Windows?

Overclocking through windows? None.

Looks like there are some modded BIOS's out on the net that should allow some fsb OCing. I've sucessuly done them on the S754 version of that board. It is not for the faint of heart.

You best bet is to try to find the clockgen chip on the board, a long ~20 pin chip that has the letters "ICS" on it and then some numbers. Then see if setfsb has support for that chip thumb.gif

Link to where I can find modded BIOSes?

Oh yeah it's an LA not LE.

I'll check for setFSB support later today.

This was similar to the first board I ever overclocked on I believe.

Mine was an HP OEM board.

I had no BIOS options so I resorted to using nVidia nTune

Thanks, nvidia ntune/system tools worked on the athlon 64 3800+ in it. It'll probably work for the Opteron 180 too that's on the way.

any idea how far i can get on stock volts?

2.6? 2.7? 2.8?

A bit late on this but just in case you were still wondering...

I was just overclocking my opty 180 w/ stock volts today (it's my backup rig I just upgraded from a fx-53 single core to the opty on the cheap). Stock volts highest I got stable is 2.7ghz. Also, as a heads up if you have any am3+ coolers around, they make excellent heatsinks for these cpu's. I put my stock FX-8350's cooler on it and let's just say it keeps the oc'ed opty nice and cool considering it's designed to cool a 125w, 4ghz 8core thumb.gif
