I've tried overclocking the 5200+ changing the FSB from 200 to 218, without changing voltage. System crashes / doesn't boot up past BIOS.

Anyway, just to get an idea from you guys, I want to get the system overclocked by 266MHZ, to make it 3GHZ from 2.66GHZ. Question is, what should I set the FSB to, and what voltages work best with this CPU & Mobo. I am only looking to get around 266MHZ out of the chip.

First of all, is it possible? I don't want to mess with voltages as I don't know much about it. But hopefully someone here can help me out setting voltage for a 266MHZ increase in speed. At the moment, I have it 130MHZ overclocked on stock voltage.

Thanks

Anyone?

Does it boot at 218? From what i understand that board is good for 300HT, so 266HT should be achievable. Firstly i would drop the memory divider, have it set to 533DDR or 667DDR at the very least. V-core, on air i wouldn't go any higher than +0.1V or +0.2V.

Might need to drop the HT multiplier and increase chipset voltage a little. What about V-DIMM, what voltage do they require? I'd set this manually. And update the BIOS version if you haven't done so.

I've acheived 3GHZ at last, no crashes yet. Have to test with some benchmarking.

I set the vcore 0.175 higher than normal, which is 1.300. So thats set to 1.475 (thanks guff for pointing out 0.1 to 0.2 would be good.

I have the FSB set to 230 x 13 (3001MHZ)

My ram is running at 860MHZ (430 x 2) on 800MHZ Corsair RAM.

Upped the HT, Chipset by 0.1v

seems to be running sweet so far, except the CPU is running at 55 degrees, on idle. Usually around 40 degrees.

I'll run some benchies, and test it out now. Any more info would be great.

Nice o/c. 55C idle is high, i'd hate to imagine what it reaches under load.

Are you using the factory HSF? If so i think it's time to invest in a better cooler.

Use CoreTemp that's pretty accurate, orthos or prime to stress.

Edit - You can drop the V-core a bit, maybe 1.45V and see how it goes. No point having more voltage if it's stable at a lower setting but just contributing to heat.

I ran a stress test, using 3DMark06. When it run through the CPU test, sidebar closed, and restarted.

I set the HT, and NB<>SB voltage up to 0.2 overvoltage, and going to try again.

I might drop the memory speed a bit next, just a little and see how that goes too.

Off to another test

You can lower the HT multiplier, it should be alright at 4X. By default it's set to 200x5, and your board is rated for 1000HT.

Did you up the V-DIMM at 860DDR? You should, or lower it to 533DDR.

Couldn't get a stable overclock at 3001MHZ. Tried all your suggestions.

When I ran SP2004, and did the CPU stress test, i got errors.

I have it stable at 2800MHZ, running the ram at the full 400MHZ (800 DDR2) I'll just stick to these settings. And the only thing different is the vcore, @ 1.375

Running much cooler now @ 41 degrees idle

Ah OK, so you set the initial memclock to 533? Yes i think it's a wise move to keep that v-core down to a moderate level until it can be cooled properly.

I've tried everything, except put the voltage even higher on the vcore.

Also I am only running stock HSF.

Been running 4 instances of Prime, cpu tests, for around 20 mins with no errors, @ 2.8GHZ. No chance at running it at 3GHZ, damn.

Makes me want to fork out 300 odd dollars to get the 6000+ CPU.

Not doin' it though, waiting for the AMD quaddies to come out, Q3 this year, and after some time, purchase one, when the price is right.

Best I could get out of my 5200+ was 2.92Ghz (224x13) and 1.450V but it got too hot and couldn't maintain a stable overclock even with a Zalman CNPS9500 AM2.

Don't have it anymore, just about to fit the 6000+ and try that out.

Re the RAM, try to keep it as close to 800Mhz as you can, or even loosen the timings and run it faster, I have 2x 1Gb Corsair and it runs quite well at 920Mhz (2x 460Mhz) with looser timings.

I'm running at 2866MHZ now, 220 x 13 and vcore @ 1.400V

Stable on original HSF.

Not going to try any higher. Temps are still ok @ 44 deg idle.
