Increasing Voltages & Extreme OC HD 4890 Using RivaTuner
April 11, 2009 by Cabro · Leave a Comment
This may not be new to some out there but at least it is for a few others and I.
I bought an MSI HD4890/1GB recently and was really excited when I found that my card could do about 980~1000mhz on the core for benchmarks. Its actual stability was around 970~980mhz
It was really cool but I wanted more.(Well, who wouldn’t?)
The thing is, the max available limit on CCC (Catalyst Control Center) was also 1000mhz.
Some days back, Guru3d.com released an overclocking article on the HD4890 over here.

They also provided the 4890 config file for Riva Tuner.

Great, so now I can use RivaTuner to adjust the limits above 1000mhz on the GPU core.
But there are are cards that don’t even hit 950mhz stable at all. We just need a slight bump in voltage to stablise that.

1GB Extreme Fast Large-capacity GDDR3 memory
Today‘s game, such as Crysis, Alone in the Dark 5, Stalker: clear sky, they normally use a large number of bump texture, transparent texture to describe faces of characters and render realistic gaming scenes, so these games put higher demands on the capacities of video memory. The current situation demands at least 512 MB video memory to run these games. Compared with ordinary GeForce GTS 250 graphics cards on market, Calibre X250G 1GB GDDR3 Graphics Card comes with incredible large 1GB GDDR3 video memory can let mainstream users to pass the 3DMark Vantage High Test which strictly demand at least 512MB video memory, providing much more detail information to mainstream users for better understanding its graphics capability. -
Extreme Cooling with Calibre Dual Fly Fan System

How To Overclock Your Graphics Card
April 24, 2008 by Cabro · Leave a Comment
Tomshardware has put together a great tutorial on how to Overclock your graphics card.
Overclocking is more popular than ever. And since it’s so easy to boost the frequency of your Intel processor, it would be a shame not to. But CPUs aren’t the only components that can be overclocked. The GPUs on graphics cards can also be speeded up, and so can their memory. And since an affordable card only differs from more expensive ones in its clock speed, overclocking can be your key to some real savings.
Overclocking a GPU is a less common process than overclocking a CPU, and above all, it’s more complex. One of the reasons for that is that a graphics card’s BIOS is not as easily accessible as a motherboard’s. This article will shed some light on the different methods that can be used and the results you can expect when overclocking your graphics card.
