You are a PC Support technician and you have been asked to select components to build a computer that will be used for CAD/CAM (Computer Aided Drafting/Computer Aided Manufacturing). Which components are the BEST TWO choices?
- MIDI sound card
- Onboard graphics
- Triple channel memory
- TV tuner
- Socket 1366 CPU
The correct answers are at the very bottom of the page – this will give you a chance to think about it!
A+ 220-901 Exam Objectives – Main Domain: 1.0: Hardware
Sub-Objective: 1.6 – “Differentiate among various CPU and apply the appropriate cooling methods.” > Socket types.
Intel’s 1366 platform uses an enormous 12MB L3 cache, a triple-channel RAM design as well as a superfast system bus, QuickPath Interconnect or QPI. Although not the latest technology, thanks to Hyper-Threading, this is still a very popular solution on many parallel processors, with the ability to service 12 threads simultaneously. However today Sandy Bridge Core i5 (not in the A+ exam objectives) is a strong alternative. Bottom line is if you are using really processor heavy software like CAD/CAM 1366 is clearly a contender.
Triple channel memory as the name indicates trebles the memory speed and performance. Not too many processors handle this but The LGA 1366 platform does support DDR3 triple-channel. It typically would run 1333 and 1600MHz but, on certain motherboards, it can run at higher clock speeds.
The correct answers are: 3) Triple channel memory, and 5) Socket 1366 CPU
