Overclocking Radeon HD4670

  • 8

Hi again and Happy New Year to everyone 😀

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?

  1. while overclocking the GPU offers only a small boost, it is often noticeable (in your card you will gain about 6-7% performence boast)

    overclocking has very little impact on the GPU temperature when the card remains at the stock voltage (so overclocking on a videocard on a desktop PC is safe and recommended (the amd/ ati drivers will even do it for you (though not as good as if you were to manually do it)

    And as long as temperatures are not near the factory limits, overclocking is safe, just make sure your card dont cross 80°C, (70 is safest, 75 is managable and above 80 is red zone in mid to low range cards, but in high end some of them go to 100+ still safe for them as they are designed to run safely even on that hot)

    In short if 6-7% is not significant for you and there is no reason to Overclock it but at the same time there is no reason not to Overclock it either as long as its in safe Temperature.
    HAPPY OVERCLOCKING 🙂
