Introduction

Like all graphics cards, the Radeon X1900 XTX occasionally needs to be opened up and cleaned in order to function properlly.

Once you remove the heat sink, you’ll need to reapply thermal paste to the GPU die. Follow our Applying Thermal Paste Guide for detailed directions.

• Q-Tips

• Phillips #0 Screwdriver

• Arctic Silver Thermal Paste

• Arctic Silver ArctiClean

No parts specified.

2. • The fan’s power cable is located towards the bottom-left of the card.

   • Disconnect the cable from the card.

   • The cable and its connector on the X1900 are fragile. Be careful, and try not to use excessive force when removing it.

   Edit

3. • Removing the heatsink from the card:

   • The clamp is held on by four small Phillips screws. Remove them, then the clamp.

   • Remove the four phillips screws surrounding the clamp.

   Edit

5. Edit

6. • Replacing Thermal Paste:

   • Using a Q-tip/cotton swab and rubbing alcohol, clean the copper plate that protrudes from the bottom of the heatsink.

   Edit

7. • Removing the heatsink’s plastic cover:

   • Remove these Phillips screws.

   • Seperate the plastic cover from the metal heat sink.

   Edit

8. • Cleaning dust out of the heat sink:

   • Using a cotton swab/q-tip, clean the edges of the heat sink. You can also use canned air if available.

   Edit

9. • Using the same method that you used to clean the copper plate, clean the surface of the GPU die.

   Edit

10. Tool used on this step:

    Arctic Silver Thermal Paste

    $21.99

    • Re-Applying Thermal Paste:

    • Apply a small glob of thermal paste to the corner of the die, (I recommend using Arctic Silver 5) and use an index card to spread a thin, even layer of it over the surface of the chip.

    • For more detailed directions, follow our Applying Thermal Paste Guide.

Back in August, we reviewed ATI’s all-new high end video card, the Radeon X1950XTX 512MB. It was the first video card to come with GDDR4 memory clocked at fairly dizzy 1GHz (2GHz effective). On the same day, ATI also announced the Radeon X1900XT 256MB at a pretty incredible $279 price point.

It comes with the same specifications as the original Radeon X1900XT 512MB, but with only half of the memory footprint in order to reduce the price. Now that retail stock for Radeon X1900XT 256MB is available in the UK, we thought that it would be worthy of a closer look. Join as we investigate whether the Radeon X1900XT 256MB is a worthy competitor for NVIDIA’s GeForce 7950 GT and GeForce 7900 GT parts, and whether the reduced memory quantity makes any difference to performance.

Core Clock: 625MHz
Memory Clock: 1450MHz
Price:Connect3D — £170.36 inc VAT

The Radeon X1900XT 256MB is a familiar sight to anyone that has seen the 512MB version of Radeon X1900XT or ATI’s previous high-end Radeon X1900XTX card. If you are unfamiliar with the GPU architecture, we recommend giving our Radeon X1900 family review a read.

Both PCB design and layout are exactly the same as the other cards that make up the Radeon X1900 family — you also get the familiar Radeon X1900XT reference cooler. In fact, the only difference between this and the 512MB Radeon X1900XT is of course the memory quantity. It shares the same characteristics under the heatsink too, meaning that there are 48 pixel shader processors, 16 texture units, 16 pixel output engines and 8 vertex shaders packed into the 384 million transistors that make up R580.

We’ve not been particularly impressed with the noise that ATI’s reference cooler emits, but it’s still present on this card. It’s a shame that ATI didn’t choose to include the same cooler that it has used on the Radeon X1950XTX, but there is probably a reason why the company chose to stick with the older cooling solution. We think that it was to keep costs down in order to allow the card to come in at an incredibly attractive price.

To some extent we can forgive ATI for choosing to do this, but we must attach a disclaimer – the card is not particularly quiet under heavy load, as the fan often spins up above its idle state. Although it doesn’t spin to 100% speed, it’s still louder than NVIDIA’s GeForce 7950 GT reference cooler, subjectively speaking. If you’ve got sensitive ears, we recommend looking at a replacement cooler from someone like Arctic Cooling or Zalman.

The card uses eight Samsung 32MB BC12 DRAM chips rated at 1.2ns. These should be good for 833MHz (1666MHz effective), so there should be some room for overclocking – we’ll have a look at that in a bit. In terms of connectivity, there are two dual-link DVI ports, just like the Radeon X1900XT 512MB. There is also a VIVO port on the back bracket, powered by the familiar ATI Rage Theater 200 chip.

AMD/ATI to supply GPU for next generation Xbox

According to Fudzilla, various industry sources are confident that the graphics processor for the next generation of Xbox will be supplied by AMD, which bought GPU manufacturer ATI more than three years ago.

According to Fudzilla, various industry sources are confident that the GPU for the next generation of Xbox will be supplied by AMD, which bought GPU manufacturer ATI more than three years ago.

It seems that the Xenos graphics chip, created by ATI for the Xbox 360, satisfied Microsoft, and the Redmond company decided to entrust the graphics of the new Xbox to the same guys.

The source claims that a new generation of consoles could start as early as next year, but due to the economic crisis, Microsoft and Sony decided to postpone the launch of the next next-gen until 2012.

So far, nothing is known about the new GPU, but Fudzilla believes that by then the 28nm process will become standard.

It was smooth on paper, but forgot about the ravines — the expression perfectly describes the situation in which the Xbox Game Pass service found itself. Plans to capture the global gaming market by Microsoft in a collision with reality proved to be untenable. And while the service has proved viable, unlike Google Stadia, its future is questionable.

The second life of Cyberpunk 2077 came suddenly. With the release of a major patch and anime based on the game, interest in the project has grown more than at release. What have they added, how have they improved the game, and is it possible to break into the world of Cyberpunk without fear of bugs and brakes? Few people will like the answers to these questions.

We can only judge the state of the game by the trailers, and it remains to be seen what will await us at the exit.
