3.5 Complete diagnosis of a system with CPU-Z

✅ Transparancy levels

• CPU-Z always shows a warning that it might have transparancy levels
• transparancy levels: i will show you everything except the things limited by the manufacturer
• how much it can show/or not
• If you have a high transparancy level, you cannot see many things from the manufacturer

• The manufacturer can hide some things they do not want you to see

• 👀 HP has a high transparancy levels
  • application HP Sure Sense lets you deactivate the transparancy level settings, and you can see

✅ CPU-Z

• CPU-Z: to check specific things for your computer
• there are 6 labels

1️⃣ Label CPU

• ✔️ name: model/name of your microprocessor

• ✔️ code name: family to which the processor belongs

• ✔️ package: if your socket is LGA or PGA or BGA(microprocessor has balls, not pins nor holes) or IFP(Integrated Form Platform, CPU is integrated on the motherboard, so you cannot take it out)

• if you do not see anything, grayish, means transparancy level

• ✔️ Technology: distance between transistors in nano meters
• nano meter: (nm, 9 decimals, 14nm = 0.000000014nm, in total 9 digits)
• if technology is small it means transistors are very close to each other ➡️ high temperature, faster communications, high speed
• so if technology is a small number, need better refrigeration, but faster

• technology ⬇️ faster ⬆️

• ✔️ Max TDP: Thermal Design Power
• number of watts that your computer can dissipate/resists

• maximum capability of resisting the heat

• if Max TDP is 15.0w, it means your computer can get as warm as a bulb that has 15w
• if Max TDP is small, it means the computer does not dissipate/resists very well, your computer gets very hot
• if Max TDP is big, it means you are dissipating very well, your computer will not get hot

❓ If Max TDP was 20, instead of 15, how would your computer be?

👉🏻 better, it resists more, dissipates more

❓ If you want to bring your computer to the beach?
👉🏻 bring the one with bigger TDP

• ✔️ Core Voltage: maximum level of volts considered 0, resistance to peaks
• 0 is 0.5v and 1 is 5.0v
• up to which level(bolts) it is stilla a 0
• so in the picture, until 0.970v, the computer would consider it a 0
• 👍🏻 if Core Voltage is high, the computer is more resistant to peaks in the electric systems

• if Core Voltage is low, the computer can lose information in the case of a peak of electricity

• ✔️ Specification: the speed of the clock or generation of the micro processor(CPU)

• the higher the generation, the most modern manufacturing process
• if the number at the end, if it appears, with GHz, it tells you the clock speed

• 2G means 2 thousand million instructions in a second

• ✔️ Instructions: ISA, Instrucion Set Architecture

• instructions that come by default with the CPU
• if you see 64 anywhere, your architecture is x64
• if you do not see any 64, your architecture is x86

• an alternative for checking motherboard architecture, alternative for msinfo32, systeminfo

• If you have an Intel + VT-x your computer can use virtualization from manufacturing
• you can use virtual machine just by factory settings
• however, if you do not VT-x, virtualization needs to be activated in the BIOS
• 👍🏻 activating in the BIOS is more secure,

• than being activated by the factory setting

• If your processor is AMD, the instruction for virtualization will be AMDV

• ✔️ Core speed: similar to the clock speed
• if you do not see the clock speed in the specification, you can see it in core speed
• it keeps changing, bc its the real speed of the clock at this moment

• the pace that the computer is following at that moment

• ✔️ Bus speed: speed of the front side bus

• higher the faster

• ✔️ Cache: how many cache you have and the capacity
• multiplier means the number of cores
• 2 x 32KB means there are two cores
• L3 is shared among cores, so there is only one

• if you want to see how many cores you have, you can see here

• ✔️ cores: how many real physical cores I have in my CPU
• if you have 4p + 4e this means p: real cores, e: efficiency cores

• your computer is so fast, that although you have 4 cores, it is acts like an 8 core

• ✔️ Threads: how many logical cores, how many thread in total I have

❓ Cores = 2, in total I have threads = 8, how many threads per core do I have?

👉🏻 4 thread per core

2️⃣ Label Memory

• information about the RAM

• ✔️ Type: Type of SD RAM(Synchronized Dynamic)
• SD RAM has the same speed as the clock
• DDR1 means 2 to the power of one, 2 times of read and write at the same time
• DDR2 means 2 to the power of two, 4 times of read and write at the same time

• DDR3 means 3 to the power of three, 8 times of read and write at the same time

• ✔️ Capacity: size of the RAM

• ✔️ Channel: dual/triple/quadraple channel
• dual: two sets of two slots of RAM, up to 4 RAM
• triple: three sets of two slots, up to 6 RAM

• quadraple: four sets of two slots, up to 8 RAM

• 2*32b means you have 2 slots, and 4GB of RAM each, so you can have up to 8GB

• this means you have only single channel, only two slots, no set

• ✔️ DRAM Frequency: how many times per second you can access your RAM

• if 798.7MHz, means you can access the RAM 798 million times per second

• Important to have a combo of type and DRAM frequency

In the photo per second,
you can access the RAM 798 million times and can do 8 read/write

• ✔️ Latency: waiting time since you accessed the RAM, until you get the information
• waiting time from access to getting the info
• latency ⬇️ less delay

❓ Frequency = 800MHz
Type = DDR4
Latency = 11.o clocks

I can access my RAM 800 milllion times in a second
in every access, I can get 16 informations
But I have to wait 11 clocks until the results come out
