طريقة تركيب المشتت على كرت 4870 HD

The first thing we've got to do is to remove the black backplate; this will be done by unscrewing the little screws that keep it into place; be warned that there are 2 more screws that have to be removed from the top of the board:

We can see that all the thermal pads remained on the backplate, after its removal:

The next step is to remove the GPU backplates; we will not use their screws anymore, so we will have to remove the springs from the screws:

After the removal of the top heatsink, some thermal pads can still remain on the RAM or VRM components; we have to remove the rest of them from the PCB and put them back onto the original heatsink (if we decide sometime later to replace the custom cooling with the original one):

To install the included heatsinks on the VRMs, we first have to locate them on the board and place on them the suitable thermal pads. Do not forget to clean them thoroughly before applying the pads!

The thermal pads are protected by a transparent film on a side and a blue film on the other side. The protective films are not that easy to get off and one of the blue films I have tried to remove from one of the pads broke a little (it was practically almost stuck (or glued) to the thermal pad):
Here is the damage caused by the blue film, while trying to get it off:

Here is how the thermal pads do look after they have been attached on the VRM components:

After the thermal pads have been attached, we have to place the heatsinks; this is also a process where we have to be extremely careful: if we place them with the PCB facing up, we can get a lot in situations where the hole on the PCB is not aligned to the hole on the heatsink, to fit the screw in, so we will have to do a lot of reseats. This is very hard because before after each reseat, we have to put the thermal pads in their places too, on the components, because they will stick to the heatsink each time:

For fixing these 2 heatsinks, we have to reuse 3 pieces of the old screws that came with the board:

The next step would be to install the cable extenders, on both 6-pin and 8-pin connectors on the board:

We have some unused thermal pads left, so we will use them to cover the memory chips and the PLX chip:

Next, we have to fix the rest of the screws into the backplate:

Before installing the GPU backplates, we have to use the provided screws and put on them the springs that we have removed earlier:

After that, we have to tighten the screws in X, as indicated in the manual:

Here is the video card, installed in the case, while the system is on:

إيه الموضوع الرهيب ده ... ما شاء الله

بس مش شايف إنه غالى حبتين ....
78*5.4 = 421 جنيه
د غير الجمارك و الشحن و خلافه

بس ممكن يكون السعر ده مبرر
لانه موجه بشكل أساسى لكاسرى السرعات
