Sorry about the Samsung!
Got fed up and frustrated and RMAed the drive for a refund. Ordered a Sony BD-RE for my machine and will swap out a known good Sony DVD+RW for the other machine (its for use in the home so its not as though I am cheating anyone).
Off topic aside ...
Really disappointed by the build.
- Gigabyte GA-880GM-USB3(rev. 3.1) motherboard
- AMD Phenom II x4 965 CPU
- 8Gb Corsair Vengeance DDR3 1600 memory
- 1Tb WD Caviar Black
The motherboard has integrated Radeon HD4250 graphics with the latest catalyst drivers. The BIOS limits the onboard graphics to a maximum of 512Mb allocated - which is a pity since the mobo supports 16Gb it would have been nice to be able to allocate 1Gb or even 2Gb).
Running Portal 2 on the machine I have had to reduce the resolution by about 30% and drop down all the settings to medium or low. Disappointing.
Its the first time I have used this board (other Gigabyte GA-880GMA-UD2H boards have been much better)! The graphics are really not good for gaming even though it is well above the system requirements.
Portal 2 requirements:
OS: Windows 7 / Vista / XP
Processor: 3.0 GHz P4, Dual Core 2.0 (or higher) or AMD64X2 (or higher)
Memory: 1GB XP / 2GB Vista
Hard Disk Space: At least 7.6 GB of Space
Video: Video card must be 128 MB or more and should be a DirectX 9-compatible with support for Pixel Shader 2.0b (ATI Radeon X800 or higher / NVIDIA GeForce 7600 or higher / Intel HD Graphics 2000 or higher).
Audio: DirectX 9.0c compatible
I am going to try shoving in a PCIe card and switch off onboard VGA.
