Overclocking my AMD Athlon II X2 240 on stock cooler

post #1 of 10
Thread Starter 
Hello there,

I have overclocked my AMD Athlon II X2 240 from 2.8 GHz to 3.5GHz @ 1.45V on stock cooler with no case fans
My RAM is @ 1000 MHz when the CPU is @ 3.5GHz.

I tried going onto 3.6 GHz, but had a BSOD. Is there a way I can go higher?

Thanks

how are your temps? dont really want to go over 61c especially when OCing. can try bumping up your cpu-nb voltage, usually helps amd chips with stability since the IMC's are pretty weak

Make sure you lower your HT and NB multiplier to eliminate those as the problem.

My temps are about 56-58 degrees celcius on full load. By how much should my CPU-NB go up? NB -VID currently is 1.75. NB Core is at 1.3.

I don't have the 3.5 GHz on 24/7 though. I have it as a profile in my BIOS.

@ above, both are at 2000

You need to test for bus speed limitations, or (FSB) as some people would say, but don't get me started on that.

Lower your CPU multiplier to the lowest. Increase your bus speed to your current 3.5ghz, the bus speed is about 250 I believe with a 14 multiplier. Increase your bus speed by 2 - 3 mhz and test each time.

Repeat this step until anything you do will not stabilize your system. This will be a good indication of the bus speed limit of your motherboard.

The main focus here is you need to stress test for at least 15 - 20 minutes if using Prime95 or 5 passes if you are using LinX (or any Linpack testing) each time you make an increase.

What about my RAM? How should I set that? If I put it to the lowest multiplier and increase the FSB to match 3.5 GHz then my RAM will be all different. What should I do then?

The minimum is 4 on the multiplier. My FSB should be 875 to achieve 3500 MHz. That is madness. How would my ram speed look like?

EDIT: I use AMD Overdrive's stability test to monitor temps.

What you're trying to do is find the max FSB of your motherboard. This is so you can see if you are maxing the FSB capability of your motherboard. As you stated in your OP, 3.5ghz was your max and you couldn't get farther, well to see if 250FSB is your max for your motherboard, this is the way to find out.

AMD's Overdrive tests are just not very indicative stress testing. I've used it before, but never to stress test for daily use. Someone else may have and can probably chime in. You should go ahead and download Prime95 along with LinX to do your stress testing.

Your RAM should have a multiplier too, sometimes they are listed as ratios or as speeds.

Example: on my MSI board, photo attached, it uses ratios. If your cell menu is similar then just use the 1:1 ratio. It should also tell you the expected memory speed. You'll have to play with your bios settings, as not all bios are similar.

My doesn't show 1:1. Might be because I need to update my BIOS, which didn't work (refer to my thread about MSi BIOS update)
