Hi again and Happy New Year to everyone :D

Just wondering if you guys could give me some tips on how to overclock my graphics card.

I have a Sapphire Radeon HD4670 1GB

CPU: Intel Pentium D 820, 2.8ghz, dual core
Motherboard: Intel 945G Viiv
PSU: Corsair 400W, 12V@30A

1x Sata HDD and 1x DVDROM.

The Radeon's mem clock is currently @1600MHz, how far up can I go? I've never overclocked before, don't want to damage anything. Can I overclock my cpu a bit too? I don't want to put them at their very limits, but I wouldn't mind speeding things up a bit.

Thanks in advance.

PS: Can someone tell me what other faster cpus (core 2 perhaps?) fit in the mobo socket?

Use ATI Tool for overclocking the gpu.


You should be able to push the memory clock speed to 1800ghz without a problem and the core clock speed to 950ghz without a problem, but increase both by 10mhz and run the artifact test on the ATI Tool each time and if everything checks out fine, then Increase both again by 10mhz and run the artifact test and so on and so on until artifacts start showing up on the test, then you will know when you reached your limit. Once that happens back the clock speeds down to the last overclock speed where you didnt' see artifacts in the test.

You're stuck overclocking the Pentuim D because your motherboard is a OEM motherboard with no overclocking features to it

And your motherboard doesnt' support Core 2 of any kind. So the best you can do is a Pentuim D 9xx series.

Are those any good? Able to handle current gen games with no problem? Or should I invest in a new mobo?

I don't want to waste much money atm, just bough the gfx card and a psu, but no point in buying a 9xx if I will need to upgrade mobo soon. Could you recommend a few mobos around the $100 mark?
(Don't know if they're all the same size, how will I know if it fits my tower?

About ATITool, do I Enable ATI Overdrive and max the settings on Catalyst Control Center? Or leave I leave it default and disabled?

You will need a new motherboard to be able to take advantage of any Core 2 processors.

And no it wouldn't be worth upgrading to the Pentuim D 9xxx seeing as you won't see much performance gain compared to what you have now.
