Over the next few weeks it's going to be interesting to see what both sides do when it comes to overclocked models. While we know that companies out there won't push the cards this high, we should see some companies who like to live on the edge give us a core of around 700MHz and a memory clock around 2400MHz DDR. Like the HD 4890, we see a good boost in performance thanks to the overclock we've achieved here. Bumping the card up 10MHz - 15MHz at a time and running a loop of 3DMark Vantage in between lets us find a sweet spot for clocks.īased on a GTX 200 series product we have a shader clock unlike the HD 4890 in this case we chose to keep it linked (an option under RivaTuner) with the core, meaning both increased together.įinally we leave with L4D and like we've seen all along, a nice boost in performance with the overclock is what we have here.
Utilizing RivaTuner we took the time to increase the GPU, Shader and Memory clock. Operating System: Windows XP Professional SP2, Windows Vista SP1 64-Bitĭrivers: ForceWare 182.06, Catalyst 9.2, Catalyst 8. Hard Disk(s): Western Digital 300GB Velicorapter (Supplied by Western Digital) Motherboard(s): GIGABYTE EX58-UD5 (Supplied by GIGABYTE) Processor(s): Intel i7 920 3.8GHz (190MHz x 20)Ĭooling: Noctua NH-U12P (Supplied by Noctua) From there we will get stuck straight into the benchmarks and see what kind of performance increase these new clocks give us.
How far up did we move from the stock 733MHz core and 2268MHz DDR memory clock? - Jump forward a single page and you will find out. With RivaTuner installed and plenty of spare time, we went on our merry way to increasing the memory and core clock to a point which gave us a nice increase in performance, whilst still being completely stable at the same time. While overclocking on NVIDIA cards is slightly more involved due to the fact that the drivers don't have any embedded overclocking software (unlike ATI with its Overdrive functionality), NVIDIA's cards do only require the installation of a small program called RivaTuner to get around this. Today we take a closer look at how NVIDIA go with the new GTX 275 which has just been recently released to compete against the new ATI offering. Recently we looked at how the new HD 4890 from ATI went in the overclocking department.
