Lay the ribs on the top rack of the grill (away from the coals, if you're using briquettes). Reduce gas heat to low, close lid, and leave undisturbed for 1 hour. Do not lift the lid at all. Brush ribs with barbecue sauce, and grill an additional 5 minutes.
You can store about 27 hours and 30 minutes of video on a 64gb memory card.
The memory capacity of most modern video cards ranges from 1 GB to 12 GB. Since video memory needs to be accessed by the GPU and the display circuitry, it often uses special high-speed or multi-port memory, such as VRAM, WRAM, SGRAM, etc. Around 2003, the video memory was typically based on DDR technology.
