Pushing a CPU beyond stock speed.
What is Hyperthreading?
Simultaneous multithreading of a single core.
1 pipeline handling 2 lines of code.
Most common CPU manufacturers
Intel and AMD

Hyperthreading
What is pipeline stall?
When lines of code requested are not ready for the cores.
Lines of code requested that are not ready for the cores will cause?
Pipeline stall
Level 1 Cache
Smallest but fastest cache that runs at CPU speed.
Level 2 Cache
Medium size, medium speed, feed L1 cache.
Smallest but fastest cache that runs at CPU speed.
Level 1 Cache
Medium size, medium speed cache.
Level 2 Cache
Level 3 Cache.
Biggest cache slowest speed, closest to motherboard speed.
Biggest cache slowest speed, closest to motherboard speed.
Level 3 Cache.

What is CPU caching
Small pieces of data held closer to the CPU from the RAM in order to access when needed by the CPU.
What is Microarchitecture?
The circuit diagram of the CPU.
What is PGA and who uses it?

What is a CPU socket?
Mount where CPU connects to the motherboard.
What varies family to family of CPU’s?
Microarchitectures.
What is different for a CPU socket that others? (type of installation socket)
Zero insertion force.
Installation process for CPU
- Anti-static wristband.
- Grip on the edges.
- Check orientation, align with notch.
- Drop in, do not force.
- Check level.
- Close arm.
What is an OEM fan?
Orginal Equiptment Manufactuer provided CPU cooling fan.
What is Thermal paste?
A paste used to assist with heat dissipation between CPU and heatsink,
Used due to the non perfect finish of heatsinks and CPU lids.
As well as motherboard CPU connector what also must be connected to be powered?
CPU cooling device typically fan.
What are the components of a watercooling system?
Pump, radiator, cooling block
What are the benifits of watercooling?
Quieter and pulls more heat away from the CPU.
How is overclocking acheived?
By adjusting base speeds of the motherboard bus and/or multiplier of the cpu.
