Gigabyte HD 4550

I have a few questions about this product, because I have two being used in a CrossfireX setup.

OS:  Windows XP 64-bit.
Motherboard:  ASROCK 990FX Fatal1ty Professional

I have installed the drivers from the original CD and have even updated drivers from the website. 

With that said, when I look in ATI CCC, it reads the graphics adapter as "ATI RADEON HD 4300/4500 Series [SyncMaster]." 

The cards themselves are HD 4550.  Why would it be mentioning 4300?

Additionally, this card is official advertised as having 512 MB of memory (half a GB), but Windows reads it as having 1024 MB of memory (1 GB).  CPU-Z also happens to say the cards have 512 MB of memory.  What is true case?  Could my cards actually have 1024 MB each?

So what's up with this?

Hi DanSan, 

Try with GPU-Z
and come here again.

It is only saying that the cards are that series not a specific card.

Try removing one of the cards and then check what the size of the memory then shows.

GPU-Z reads each card as having half a gig memory.  I suppose this confirms it.

Though before either card were loaded into my present machine, both were used (but not at the same time) in another computer.  My brother reported the memory as being a full 1 GB with each card.  He showed me in CCC and in Windows.

So maybe that's just not the case I suppose.
