I need help with my ram specs please?

Question

I am in the middle of upgrading my computer because its annoying spending all the thousands every time i buy a new computer to update, and the computer i have now i got 2 years ago and its quite decent and its everything i want minus a thing or 2,

my question is the computer i have came with 512mb ram, and i just wanted to add 2gb ram in total since i have 4 ram slots, so i went out and got 2gb worth of ram 4 x 512mb, but after i inserted them i checked the properties on my computer so see how much ram hoping would show 2.0gb, but for some reason it only reads 1.75gb, does anyone know why?, does this mean my mother board cant read over 1.75gb or something, or is there something else i have to do, i know about computers but when it comes to hardware i only know a little bit..

Answer 1

Chances are you are using onboard graphics that share memory.

If you are not much into gaming then you are ok.

If you want to play and enjoy current games, get a good video card (8 pixel pipelines or higher w/ 256Mb of ddr3 on board). Your 2Gb RAM would then be ALL available for processes and apps.

Answer 2

There is absolutely no problem with your computer. The 'missing' 256 MB of RAM is being used for graphics(dedicated memory) .If you want to check this, Start>Run and type dxdiag .It'll show you how much Graphics memory you have. If you want to change this ,goto BIOS by pressing Del key(incase of Award BIOS) or F2 (incase of AMIBIOS) ,as the case maybe and there under Advanced Chipset features you'll find it.

When you click on My Computer>Properties ,it shows you how much RAM Windows is permitted to use, hence the missing 256MB ( 0.25 *1024=256)

Answer 3

CL: Short for CAS Latency, wherein CAS is brief for Column Address Strobe. CL latency is likely one of the foremost parameters of a reminiscence chip. It is the time it takes to get knowledge to the information pins. Immediately following the CAS Latency, the information is to be had at the reminiscence Data-pins. Command Rate (CMD): The command price specifies what number of consecutive clock cycles have got to be despatched to the reminiscence modules earlier than the modules can ship knowledge. Because wires ordinarily have usual capacitance on them, routinely it takes longer for a twine to transition from a one million to a nil. The CMD environment is usually one or 2 clocks and will ordinarily be adjusted among the 2. It's represented as 1T or 2T. CPU: Stands for Central Processing unit. Also referred to as processor, the CPU is the lively facet of a pc wherein mathematics operations are played. Core pace/frequency: The pace of the innermost factor of an digital gadget, measured in MHz. Example: A DDR-four hundred module has center pace of 200MHz. DRAM: Dynamic Random Access Memory Dual-channel: A estate of the motherboard wherein the reminiscence bus is divided into 2 sixty four-bit channels, without problems doubling the bandwidth with regards to a unmarried-channel setup. Dual-channel isn't a estate of the reminiscence modules. Effective pace/frequency: The precise pace of a gadget in train, measured in MHz. Example: A DDR-four hundred module has an mighty pace of 400MHz. Form element: The bodily dimension and form of a gadget. FBGA or BGA: Fine Ball Grid Array FSB: Stands for entrance facet bus. The FSB is the information direction that runs among the CPU and essential reminiscence (RAM). IC: Integrated Circuit, typically known as a reminiscence chip, an IC is a small digital gadget produced from semiconductor fabric. Latency: Physical extend of the reminiscence module represented discreetly in clock cycles. Usually stated as 'C-L 3', wherein the 3 represents the extend, measured in clock cycles. The extend frequently levels from 2 to 6 clock cycles for DDR. Memory module financial institution: Logical department of chips on a PCB board. A unmarried reminiscence financial institution can also be composed of any quantity of chips. Some banks are composed of simplest two chips, while any other modules have 18 chips or extra according to financial institution. Not to be stressed with reminiscence Rank, see subsequent time period. Memory rank: The bodily facet of a reminiscence module. The facet of the module is stated by means of Rank0 or Rank1. PCB: Stands for published circuit board. A PCB is a small plate on which chips and different digital add-ons comparable to resistors or capacitors are located. Semiconductor: A fabric comparable to germanium or silicone which permits present to waft beneath distinct situations. Semiconductor elements make it viable to make vigor-effective and rapid nano-scaled transistors, which can be the elemental items of pc common sense. Semiconductor elements are used within the fabrication of included circuits, which can be used to construct reminiscence modules. TSOP: Thin Small Outline Package
