memory issue

Hello!
I change my sticks of memory to (now 2GB Corsair PC6400) which does not accept overlocking of my graphics card (Asus 4850, Zalman VF1000 LE).
My motherboard is: Intel DP35DPM, FSB1333, Intel P35 chipset, SATA, PCI-E, GLAN
Is it possible to take the memory to PC6400 / 8OO mhz with this motherboard?
I look for the OCZ PC8500 ...

the stripes of ram that do not support overclock to the graphics card? They are separated 2 pieces which count to be nothing to see. Changing ram should improve only CPU by O/C and not the graphics card. What is your configuration?

My configuration:

Processor: Intel Core 2 Quad CPU Q6600, 2.4Ghz
Memory: 2GB DIMM DDR2 Corsair TWIN2X (PC6400, 800 MHz)
GPU: Asus HD 4850, 512 MB DDR3 (with Zalman vf1000 LE)
Power Supply : Corsair VX450W : Corsair VX450W
Motherboard: Intel Desktop Board DP35DP
Hard Drive: 500GB, SATA-II, Samsung 7200rpm, 16MB

So you mean that by chaging sticks of my ram will not solve of problem of O/C my GPU?

Infact, as sson as I reach to catalyst center, my screen goes black.

In simple terms, the three are all parts of the architectural pieces that make up a video card, In reality, a video card is really a complex PCB. If you want to delve deeper into "how complex" there are lots of materials on the internet dedicated to the subject.

The *Shader* is a program (set of instructions) executed on the (GPU) graphics processing unit for rendering purposes. It used be normal for a video card to have an non-unified pixel & vertex shader pipelines for rendering calculations. With the news cards including your 9800GTX, what is now employed is called a unified architecture where no pipe is specific to one task.

The *Core* has to do with the GPU's clock speed & the *Memory* likewise has to do with the GPU's memory clock speed.
