Ray Cummings observed in 1929 that "time is nature's way of keeping everything from happening at once." The purpose of a computer's clock is similar. Computers need to deal with things that may happen in unknown sequence, and be able to declare with certainty that one happened before the other. In many cases, it won't matter which event a computer decides ...

CPUs are executing elementary instructions such as reading or writing to memory, basic arithmetic operations, deciding what to do depending on results of previous instructions and such. Each of these instructions may consist of few steps which have to be executed in that exact order. For example to add two numbers you have to: Fetch them from registers ...

Analog computers don't need a clock, so you could make a computer without one. Think vacuum tubes, they operate on differential equations over range. They are asynchronous machines but its limited what you can do given that you'd need to sample out put at some point. One could construct an event-threshold computer but synchronizing is the problem. There is ...

The name "clock" is maybe a little misleading. It does not provide the time of day. (There is a time-of-day clock on the motherboard, but that's different from e.g. the "2.2 GHz clock".) Its output is only signal pulses. The CPU clock would be better thought of as the "baton", like the one the conductor of an orchestra uses. The signal from the clock ...

It's getting into the realm of electronics, but basically a CPU's clock keeps everything in the CPU synchronized. CPUs are digital and like anything else digital, they work on the principle of "on" and "off" - however, transistors take time to fully switch on or off, and if you check for the state of one while it is transitioning, you will get unpredictable ...

That allocation is the number of GUEST cpus not the number of HOST cpus that can be used. While they are often very similar, virtualbox tries to use as little CPU as possible, they are not the same. Virtualbox, and any other VM software, will need to use some of your host CPU to emulate the other devices. (such as the video card) The fact that your mouse ...

TiWorker.exe is Windows Modules Installer Worker. It is related to Windows Updates. I am not a windows user, but it seems most windows users experiencing this issue can resolve it using this. Here is a basic summary of the article: step 1: run the system maintenance troubleshooter step 2 (if step 1 doesn't work): search for and install all windows updates. ...

Technically, increasing your memory has no direct impact in performance. It only means you can load more stuff at the same time. I know the SuperFetch will work better if you have a minimal of 8GB of memory, but thats another story. Also, you won't be able to address more than 3.5GB of memory if you are using a 32-bit system, so its helpless to try. If ...

Your CPU is probably overheating. Check the CPU temperature when in full load to see if that is the case. It may require cooler/fan cleaning, new thermal paste.

Yes and no. Yes: You can use a CPU with a less TPD than the maximum rated for that socket. Think about it like driving either a car with a maximum speed of 95kmph or a maximum speed of 65 kmph on a road which has been declared safe up to 95 kmph. And no: You can not just any other CPU, even if it has equal or less power usage. (Roughly translated: TPD ...

Load average doesn't show exactly how much the applications are using the CPU. The CPU can wait for the disk, it could spend time performing kernel related tasks, or can be severely interrupted by an action such as a key press or it could have some time stolen by the hypervisor on a VM. Perhaps atop would be a better tool than htop to monitor your system.

When processors run they generate heat. Lots of heat. Because mobile devices are considerably smaller than computers, the heat generated by a running mobile processor is often amplified and can seriously harm components, or even melt them. Therefore, the developers and designers of the devices limit, or throttle, the speed at which a mobile processor can ...

A trick I learned from a few sites: Use –-purge-memory-button in Chrome's command line and click Purge memory in Chrome's task manager and it will free up memory (if possible) Obviously, just disable extensions and that'll save you memory as well. Also, some sites have mentioned FooTab, an extenstion that pauses all other tabs upon startup until loaded. ...

The fan controller knows when to speed us to keep the temp at 55. The fan will start to spin to prevent it from climbing. It doesn't kick in at the critical temp because it wouldn't be able to cool it down quick enough. the fact your temp is staying around 50 means the fan is doing what it should be doing. Go buy a silent fan. You shouldn't be lowering fan ...

I think you're on the right track and you've essentially already answered your question. A 32 bit CPU can address 4,294,967,296 memory locations. 4GB of RAM is a total of 4,294,967,296 bytes, so how can the CPU access all of that memory and still have address space to access hardware (registers are not mapped to memory locations)? Well, it can't. It ...

Also just used toothpaste on my macbook pro 2011. It had a failing graphics card and being out of warranty I waited until it was truly dead => no boot. I took it apart, cleaned it and removed all plastic. Did a "reflow" of the motherboard in our regular oven at 220 degrees Celsius for a couple of minutes. Applied toothpaste to the cpu and gpu and put it all ...

You can always pick your laptop up (when it is running) and see underneath if you see some obvious things happening e.g. winging sound or some air being fed out. I am making an assumption that your PC/Laptop is reasonably old (>2yrs?). Depends on what things you have used it on and how much you have used it on average, The thermal layer on the processor die ...

You've exhausted what I would do, check CPU core temps then try get info regarding fan RPM. If your CPU Core temps are in the 70s-80's and you can't hear any fans (you would almost certainly hear them) then I think you have a problem. EDIT: Download SpeedFan, manually ramp up the fan RPM and if you don't hear anything then you've got a problem.

What nvidia ? The notebook uses intel "HD" 4000 graphics. Because you output a powerful display via that, the CPU will get hot. Although 65C is a little hot, it is still relatively ok. It should be kept under 60C. If it gets above 65C it is recommended you do take some measures to reduce the temperature. it's best that you remove the CPU heatsink, add ...

I did some searching for a third-party vendor-neutral taskbar utility (like Lenovo's Energy Management utility) and found Power Switch. I tested it quickly with CPUz; in power mode the CPU maxed out and stayed in that state, in balanced while playing a video it would jump all over the place and in power saver mode it just stayed at 800h MHz. Tested on a ...

What you are asking can be found by googling for "Processor timing diagram": http://goo.gl/DkEE8I Inside the timing diagram you can see when instructions is put on the bus, and when it is completed it can triggered the next instruction to be fetched etc. Yes, different instructions have different number of clocks cycles - eg, those XMM instructions from ...

You didn't specify what your hardware is, but some pc's have an onboard graphics that shares some hardware resources with the motherboard - such as main memory. If you have stacked up a lot of processes in memory, than going in full screen mode can tax the available memory, causing swapping and other inefficiencies that can lead to a cpu running close to ...

Quitting and then starting it up again has fixed the problem. No high CPU usage after syncing a FEW things, either. I think the high CPU usage might happen after syncing a LOT of items (hundreds). After syncing is complete of those items, a workable fix may be to restart Drive until they improve the mechanism.

Your application is most likely single-threaded. So it can use only one CPU core. Since you have 4 CPU cores it is using 1/4 of CPU, which means roughly 25%. In order to use your CPU to 100% you will need to modify your application to use multithreading (if possible). Not all problems can be solved in multi-threaded fashion. So it depends on what you are ...

Initial installation, and fixing stuff when the BMC is hosed. I've seen that adaptor before on blade servers, and the VGA port is a nice touch, should you have issues remembering the IP address of the BMC. It isn't the same as the ports on a video card controller, which are connected to the graphics processor on die on modern consumer systems. These xeons ...

I ended up buying the varient that includes the on-board graphics. Here's why: The price isn't very much more, so why not? I get the feeling that all the chips are really the same, and ones that are flawed in that subsystem get sold as "without". others packaged to fill demand are not tested. Do I want a "bad" chip? It simplifies setting up and burn-in ...

That is normal for 3 main reasons: the benchamrks score depends on the ram installed, whether it is in dual channel mode or not, so a core i5 with faster ram may perform faster. heat sink and cooling, those processors are usually coupled with heat sink and fans that can only dissipate heat generated by 15 watt of power, which is the required by Intel, ...

You fan looks like has stopped working and caused constant throttling due to over heating accumulation of dust. or Something dust particles went inside the hard disk or something(given that all your programs are lagging).

I agree with Jacob disassembling seems a good idea. But... What is the remaining free space on disk? This could also be a cause. Did you check if the SIMM(s) are correctly set? Did you get any error message at first start after blowing the air? If one of the SIMMs isn't correctly set due to the air flow or if the dust has been pushed inside the slot, you ...

I'd assume instead of cleaning the fan, you further clogged it (mechanically) by blowing INTO the laptop. Thus, the fan isn't able to provide the same cooling performance as it would be when operating on full power. The CPU then throttles itself down to avoid overheating.

I'd try disassembling the laptop and visually inspect the fan. It almost sounds like the fan might've gotten stuck after the second time you blew it out. It seems strange that the sound would immediately stop after having compressed air blown on it (unless the fan has physically stopped moving completely). This would explain why the computer slows down ...

This is related to intel speedstep/eist/c1e and how windows 8.1 misuses it. I thought I should disable as many variables as possible, and went into the bios and disabled speedstep. The cpu locks to a fixed speed, and the periodic issues go away. Of course I can't keep it this way except for testing. Most of the time I use the laptop for regular work and not ...

In PCI and PCIe systems, it is certainly possible. The BIOS has settings to say which is the primary, if both are present. It is subject to the usual issues of mixing graphics cards of different brands: the drivers may be allergic to each other. At least, be sure not to install the "utilities" from both as they may fight over things. Before switching to ...

To your first question, no. The P4600 is not a general-purpose computing system, it's just low-end graphics, comparable to low-end discrete graphics cards (like an 8800 GTS) that also have little use for general-purpose computing. To your second question, yes, the motherboard graphics connectors typically do use the integrated processor graphics. ...

Your best bet is to see what TiWorker.exe is and what may be causing it to use CPU. Sometimes, high CPU usage might be caused by another problem, like high disk usage. (Perhaps that leads to high disk cache usage which the CPU is involved with; I dunno. But I've definitely seen that cause and effect.) Or high memory usage, which causes disk thrashing. ...

This worked for me (all or one of this steps): Install hyperV from "add windows features". Reboot and do updates. Do a maintenance from security center. Turn off windows firewall (if you use another firewall together). Now the "worker has stopped working!" (for me).

A GPU does different kind of computation to the CPU, often matrix transformations and floating point computations. The sole purpose of the GPU is to support the CPU when handling complex display computations. When the GPU gets used will be dependent on drivers and the software itself (the software may request all computation be done on the CPU alone). ...

The first set of RAM you linked to is buffered as well as ECC which means it definitely won't work. Buffered RAM is typically for servers so you need to make sure the RAM you buy is listed as unbuffered. The second set of RAM doesn't look particularly good quality to me, and it does clearly say it's for AMD systems so I wouldn't risk buying it. You might be ...

Integrated graphics, loves memory speed. Your DDR3 1066 is comparatively slow. Your processor supports DDR3 1866. Pick up 8GB of Gskill Aries 1866 with 9 or 8 timing for $60 at Newegg. It should improve integrated graphics drastically. Won't make it better than a discreet card, but playable. You could use the leftover memory for a HTPC or something like ...

The processor is not upgradeable—consider installing an SSD instead. Your laptop uses a soldered (BGA 1023) processor, which cannot be replaced without special equipment. You should consider installing a solid-state drive instead. The vast majority of consumer workloads are not compute-bound, but are I/O bound due to the slow random I/O performance of ...

This sounds like a failing hard drive to me. Check your drive's S.M.A.R.T. data with a tool like smartmon. The windows install instructions are available here. I believe this is the case based on the sounds you're reporting, but I would imagine that Windows would give a blue screen or restart itself in that case. You say you ran 'health tests' but ...

OK. This happens when the processor is an engineering edition, hence the version will not be recognised by installed software.

Use one of these from a paper towel or toilet roll. If you stick your noise inside it while you sniff it makes your smell ability a lot more directional and makes it easer to narrow down what section of the computer the smell is coming from. P.S. This also works very well when some part of your computer is making a noise and you can't tell where it is ...

Doing a little analysis of what CPUs are supported I can safety say that ASUS P5G41-M will support the Intel® Core™2 Extreme Processor QX6700 (8M Cache, 2.66 GHz, 1066 MHz FSB) because it supports Intel® Core™2 Extreme Processor QX6800 (8M Cache, 2.93 GHz, 1066 MHz FSB) the power requirements are identical and the QX6800 was released after the QX6700.

3 things could go very hot: CPU, video card and power source. CPU temperature can be checked in BIOS. Video card GPU temperature can be seen in the driver's control center/panel (will not work for very old cards). As for the power supply temperature, in most cases it has no temp monitoring, you will just have to check how hot is the air evacuated from it. ...

I had the same issue which i just resolved, the file you are having problems with is windows automatic update service.

A CPU bottleneck basically means the CPU is the slowest part on your system, it affects you by capping everything else to its speed.

The bottleneck here is the packing machine, which results in a throughput of 12 muffins ...

I'm not sure what your problem is you are asking about. If this is a general question about "what to be aware of" then, yes you should consider the CPU performance. If the question pertains to particular behaviour of your laptop then having a description of those symptoms would be helpful. CPU Bottleneck in general refers to the issue of data flow. ...
