AX5770 1GBD5-PPGV2 Detailed Features

The fan and heatsink for the PowerColor AX5770 PCS+ is easily removed by taking out the four screws surrounding the GPU. The whole mount then comes off rather easily so we can take a look at what lies beneath. As is common with many video card manufacturers, it appears as though PowerColor hasn't read our Executive Editors advice on applying thermal interface material. There is far too much on the AX5770 PCS+ GPU.

The backside of the AX5770 PCS+ is a little crowded, but PowerColor has made good use of the space. By rearranging the PCB layout, PowerColor was able to cut off about an inch in the length of the AX5770 PCS+ compared to the ATI reference model.

It seems like PowerColor made another little change to the AX5770 PCS+ v2 as well. The first version of the AX5770 PCS+ came with Samsung memory modules. As you can see here, the AX5770 PCS+ v2 clearly had Hynix memory modules.

The Hynix memory modules on the AX5770 PCS+ v2 are numbered H5GQ1H24AFR. These modules, while "overclocked" on the PowerColor AX5770 PCS+ to 1225 MHz are actually rated to run at 5 Gbps effective speed or 1250 MHz. This is the same as the Samsung modules found on the AX5770 PCS+ v1. So while most Radeon HD 5770 cards have memory clocked at 1200 MHz, and the AX5770 PCS+ has memory clocked at 1225 MHz, we should have no problems pushing the memory to 1250 MHz without adding additional voltage.

Below you can see a close-up of probably the most crowded section of the PCB, just behind the GPU. It is clear that PowerColor has taken care with during engineering to avoid over-soldering or splash amongst the components. Even with such tightly spaced parts (and it has to be that way when you cut an inch off the reference design) they all fit nicely within their designated locations.

Now that we have taken a close and detailed look at the PowerColor Radeon HD 5770 AX5770 PCS+ v2, lets explore the features and specifications that PowerColor has released for the card.
