Help please: Overclocking 4400+ / Asrock 939A785GMH

Hi,

Hoping for some expert help here:

I have the above CPU / MOBO with 2 Gb RAM + NVidia GeForce 6600 GPU. I've had the system a while now, recently upgraded to Windows 7 Ultimate (32 Bit), and I'd like to try squeezing a bit more out of it before I consider upgrading anything. I've also upped the BIOS to F10D from the Gigabyte website.

I've taken a look at EasyTune and hate it - it seems this MOBO isn't CIA compatible anyway so I'm not going to be able to 'cheat' at overclocking. I have tried to research this but it's hard to make a start as overclocking seems to be a bit of a 'fine art'. I feel a bit like like a youngster at play school holding an artists brush for the first time, so I'd appreciate someone helping me to 'paint by numbers' to start with - then I can learn from there.

Is there a chance that someone out there can recommend a good combo of settings for the MIT settings in BIOS, that doesn't just involve upping the CPU frequency? I don't mind experimenting but I don't want to use a combination of settings to begin with that is just plain wrong. Obviously I'd like to see some effect but I don't want to screw anything up or overheat anything! Incidentally I am running CoreTemp, so I can see how my CPU is performing on the desktop.

Many Thanks - hopefully!

First of all, please put your system information into your signature by using the Add System button found in your User Control Panel (or just clicking here). That'll help us to help you easier.

Secondly, it seems that's a Socket 939 setup. There's a link in my signature for the Socket 939 club for starters.

There's a few things you can do to start. Drop your RAM speed down to 333 (or 166MHz). Drop your HT Link speed down to at least 4x (you want your HT Link to stay around 1000MHz). Then all that's really left is up your HTT clock (FSB) slowly. Once your machine is unstable, then raise voltage, and try again.

That's just a SUPER quick explanation...hopefully it helps a little.

This guide should help you quite a bit. Read it through.

Many Thanks. I've done what you asked (System Spec). Tell me if you need more information. I'm going to have a read (or at least try - I need to be 'taught'!), and maybe I'll have a go with what you suggest in BIOS and see what happens! Having said that I'll probably hold off until / if you look at my spec and make any further suggestions. To the other poster - yes, I know about Ctrl F1 but in this BIOS / MOBO it doesn't reveal any more of value. I can see the MIT options by default.

Thanks pioneer...

Edit: I had a go with the settings you suggested, but had a problem running the stability test in Everest Ultimate - test halted due to hardware failure! So, I chickened out and reset optimized defaults in BIOS - ran the stability test again with no problems. Out of interest I rebooted into BIOS, and selected the 'Top Performance' option - again, stability test runs fine with no failures. At this point I confess to being shy of trying anything else in case I blow something up. Meanwhile, here's a screen-shot of the Everest sidebar gadget with the stress test just a couple of minutes in. You can see that the CPU FSB is now at 206 rather than 200. I'm sure I can do better than this 'Top Performance' setting but hmmm...I'm not sure I have the courage!

Hey let me know what you get your 4400 to run at.. I have mine running at 2.58ghz..

Alright, try 215 FSB. Then, try 220 FSB. Then try 225 FSB. When it fails, increase vCore.

I was getting a hardware failure in the Everest test at 210! I'm not sure what 'increasing vcore' involves, or how to do it. Told you I needed my hand holding...!


What I did was to change the HT Link to 4X and the CPU / DDR ratio to 1 / 1.66 (that's the only thing I could see that changed the Memory Clock / Speed in my BIOS options. Maybe I did something wrong and / or I don't understand how to change the memory speed...

OK, to increase vCore, go to CPU Voltage Control and give it 1.55V. Also, disable CPU Spread Spectrum. Bump CPU Frequency to 215 and try again.

Hi,

I've updated my motherboard and graphics card which I believe gives me some overclocking options, but all attempts so far have failed.

Link here to my current set-up, as I was also unable to update my signature here. All help appreciated.

Thanks.
