HD 4200 + HD 3450 Overclocking

[Pocumtuck]

Hi,
I have a laptop in which I am using HD 3450. I want to upgrade the same. The solution which I found for that is HD 4200. I have a Amd Phenom X4 II 945 with 4GB DDR3 1333 RAM support. I have a Arctic Cooling Fusion 550R and Asus V-M4A785TD EVO on the system. So for that I want to ask that this will work better if I overclock the same for videos. I had overclocked my old card but that gives minimal support. Does I can increase the shared video memory it of card to get a better fps.

First of all an integrated graphics unit to overclock makes no sense. Whether you now have 3 or 4 FPS in games, you'll probably hardly notice. The most important of all, however, that temperatures will rise by increasing the clock and the video chip cooling is simply not designed for it. I will a real graphics card which has the x-times the performance and you notice a noticeable FPS difference.

That is right the shared memory you can not simply enlarge / reduce. For this you would have to change something in the driver. Makes no sense, since the onboard graphics card get according to the required RAM capacity allocated dynamically by the operating system. In the video chip itself is the brake, because he did not manage more than 4MB RAM can. This means that the chip would be faster it could handle more RAM and would therefore get more RAM.

I have a similar system.I want to play at about 750MHz, 750MHz, at least I imagine just one in the BIOS which can be under advanced features > jumperless configuration or so, then contact with VGA to adjust manually. However, because he is already home from 100MHz to overclock it comes at the end of mhz to 850. You can set the shared memory BIOS which is under advanced features > chipset features > graphics at the idle temperatures are at about 40 degrees.

As far as I know is capable of only the Ati HD 3200 HD 3450/70. More than 5-7 FPS with an IGP usually depends on the game. That can be which board do you have. Does you bios would be a better choice for overclocking. For that you can look in the Bios. However, you should install a fan on the cooler of the graphics card otherwise it scorches through the OCN. And the heat is not too intrusive. If indeed both together the GPU and the chipset is not it? So under this Northbridge cooler which is only passive.

You need to go for HD 4200 with no additional fan support. The heating of a igp is minimal. The board is cooled sufficiently at the factory. As the driver reaches the normal catalyst. The Agp is recognized by windows as a normal graphics adapter whether now is soldered or via pci-e interface-connected to the system is, it does not matter. Do you think you can operate the system generally without case fans.

The graphic chip contains its own video decoder called UVD 2 which when decoding HD videos (MPEG-2, H.264, VC-1) can support the CPU. This means that even systems with weak CPUs with HD 4200 HD movies (eg from Blu-Ray) represent liquid. The UVD 2 also supports the decoding of two video streams simultaneously (e.g. for picture in picture with Blu-Ray). he graphics core is based on a DirectX 10.1 compatible HD 3400 and by the lack of storage offers a lower power.
