It is possible that when we upgrade from Yosemetie to El Capitan, our bluetooth settings are backed up and are read by the system. I found that this was the file that had a few duplicates: /Library/Preferences/com.apple.Bluetooth.plist sudo removing all these files then doing a PRAM and SMC reset immediately worked for me! PRAM and SMC reset : Shut down ...

You should try at http://security.stackexchange.com/, they will probably be more sutable to help you. But as far as i can see it its number of combintations/calculations + per second if the password is not on the list or simple algorythem like x0=1;x1=X0+1;xn=x(n-1)+1. And it seems there is an extra time factor if using non english letters

Install the Windows Performance Toolkit, which is part of the Windows 10 SDK. Run "C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\WPRUI.exe", select First Level and CPU and click on Start. Now leave the PC idle and wait until you here the fans again. Now wait 20s and click on Save to store the trace into an ETL file. Now make a ...

Reinstalling Windows is a last resort! Resource Monitor is a more detailed Task Manager and it lists all processes by current CPU % and average CPU %, so you can hunt down whatever causes the spikes. Alo, if you're feeling a bit more adventurous, you might want to try blowing out the dust from inside your laptop with a can of compressed air, so the fan ...

You can waste weeks trying to find this issue. Mine was cleared by a clean windows 10 install and not an upgrade. Use a keyfinder to get your current key and make sure you have your old windows 8 key before you attempt a clean install. Once you have those, do the standard backups, download the USB creation tool to create Win10 installer ...

Well all you can get is the list of running processes (Task Manager). All other tools use the same data. Generally you can track processes and check how much CPU time they require, but: 1) Slow response can have a plethora of reasons 2) The fan spiking has not a lot to do with CPU usage I assume it's not a U series i7 but an M, so this is a pretty ...

As the name says, SoC (System on a Chip) is (a significant part of) a system (i.e., a computer system, a CPU, memory controller, memory, I/O devices of several descriptions, perhaps including a graphics card) on a single chip. Some of them are built for a very specific purpose, i.e., as the heart of a cellphone, or as more general-purpose machines. Some ...

SoC (System-on-Chip) as the name implies almost always contains a CPU, graphics chip, audio, video, radio, LTE and USB controllers; therefore they work in unison aka "it's a system on a chip". The CPU (Central Processing Unit) as it implies is the " brain" of the system. On smaller devices such as smartphones and tablets there is limited space. So in order ...

You didn't specify your motherboard or the type of RAM you bought. In general, what you have to watch out for is whether you bought the correct type of memory. For example, if you buy DDR4 memory but your CPU and motherboard only supports DDR3, it literally won't fit. Now, assuming you have the right type of memory, you also need to be a little concerned ...

You should be able to read scaling_cur_freq To answer the question: It seems that reading cpuinfo_cur_freq communicates directly with the hardware or - depending on implementation - the firmware which obviously shouldn't be allowed unprivileged. Source

As you can see here: CpuBoss Intel Xeon X3370 is a little bit better for everything. Without no more details I cannot help you more. I can only warn you telling that for videogames is really important also have a good GPU and that X3370 is 8 years old. (Also a bad i3 for notebook is much better) Everything depends from what you want to play.

You've clearly stated yourself your application is single-threaded and limited by single-core CPU performance. By definition, multi-core processors and hyperthreading won't help. Adding a million cores won't make a program run faster when it can only use one core. The only way to improve single-core application performance is to get a CPU with faster cores. ...

No. Simply said, if you buy four cars, you still can't go 360 mph.


0

No. Your CPU is 2.4GHz. However, your CPU has multiple cores, and/or a feature called HyperThreading. These features involve making a single CPU act rather similar to multiple CPUs, or at least multiple partial CPUs. The "2.4GHz" is your speed, and is a measurement of how many "clock cycles" you have. If you have a quad-core system, that does not mean ...

Alright so it's been a while, unfortunately last month I didn't really have time to deal with this finals and all. But now to sum it, the issue was caused by my onboard vga chip. I replaced my mobo a few weeks ago and (fingers crossed) my Pc has worked like a charm ever since. Thanks for all the helpfull ideas guys! 😊

All x86 chips should work with both VMware & VirtualBox, but you'll need AMD-V (AMD name for hardware virtualization) to run 64 bit guest OS (it's possible to run it on Bochs or qemu, but far slower). For simplicity sake, you can just search the CPU series on cpuboss since AMD own site isn't too easy to navigate.

If you have a 64bit CPU, you can use a 64bit Operating System. The chipset is irrelevant.

Another very convenient way to set the affinity of a certain executable when it launches is to use the start command. e.g. "start /affinity F iexplore.exe". If there is a single application that you want to start thus throttled, you could create a shortcut with this command. Note that the affinity is set by a hexadecimal value, which may require some trial ...

Looking at your two pictures anbd the 'rounded' corner you are missing these signals: Data 20 Data 22 Data 19 VSS (one of the power lines. It might not need this to work). VSS (one of the power lines. It might not need this to work). Now less power, or less equal supplied power might not be enough to break things, but lacking three datalines is deadly. ...

It looks like the CPU pins are broken off, thereby making the CPU unusable. The only real test would be to try a known functioning CPU. Of course, this doesnt mean the motherboard is working, either.

After updating the BIOS you need to reset it to default values because often old values don't map properly to new settings, which is why it is incorrectly reading the CPU voltage. Choose load bios defaults or the equivalent in your BIOS, reboot, and then check it. Should be fine.

This is the current speed. The result should be the same as by using the command: cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq The command cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor will indicate the power scheme for the CPU. Use the followings 2 commands to view the max and min frequency (allowed). cat ...

Turbo C 3 (C and C++ compiler by Borland) does not run well on 64-bit OSs like Windows 7, Windows 8, etc., and on 32-bit OSs, however there is an emulated version of the same Turbo C compiler within an environment called DOSBox, which works on all OSs (Windows 7/8/8.1/10 32+64-bit) fullscreen. The simulation of the popular Turbo C compiler on Windows 7/8/10 ...

Do you REALLY need to use Turbo C++ on Windows 7? It can be a lot of pain to make it work properly and there are some workarounds: Setup a VM with a old operating system and use Turbo C++ in it; DOSBox will probably work; Integrate the Turbo C++ command line tools and library into your favourite IDE and write your code there (Borland Command Line ...

The connectors on PSU's now are often 4+4 CPU connectors now. They should look similar to the following: The manual for your PSU states: B.

Be sure you're using the right connector, there are ...

So, tell your friend he doesn't have a clue what he's talkin about...

It isn't possible to upgrade to a 6th gen CPU from 5th gen, as it requires a new chipset, as well as amongst other things, laptop boards and CPUs generally can't be replaced.

The most likely failure is the power supply. Try replacing that first. BTW, if you are doing a heavy rebuild, replacing the power supply is a usual, so nothing is lost there.

If you can change the orientation of the heatsink Ideally, you'd have the heatsink rotated 90 degrees CCW from your photo, with the fan pushing through the heatsink, straight to the exhaust fan. However, I don't know if the mounts you've been provided would allow this, but this would be the perfect scenario from your image. If you can't change the ...

As you've stated, and you're not going to like my answer I don't think, there is a common fault with these laptops, and about 6 years ago at a computer shop I worked at we would see these very frequently. The machine model actually had an official recall, and it was caused by the graphics chip overheating. We did offer our customers a fairly non-recommended ...

With the help of ASUS and other forums I have found out: The ASUS Diagnose LEDs only work if the CPU is installed. In case of No-Post always connect the speaker to detect failure beep-codes. Those beep-codes can be explained with the manual, in my case the manual from the ASUS Z170-PRO, because the Z170-A manual does not include that table. The order of ...

On older chipsets (P4 era, some core2duo's) you are right. These are bandwidth starved and integrating a GPU on the same die as the CPU will reduce CPU performance. On more modern systems there no longer is a FSB (see @Lunatik's answer which is very good in that regard) and CPU performance decrease due to shared bandwidth to the memory should be minimal. ...


2

FSB and Northbridge are obsolete technologies. All modern systems work on the basis of a point-to-point interconnect (Intel's QuickPath Interconnect, AMD's HyperTransport etc.) which doesn't have a 'hub' like a Northbridge or a bus with limited global bandwidth as was the case with FSB. This alone reduces the burden on system resources, but the fact that a ...

Why is the amount of RAM usable by a computer limited by the processor bits? It isn't. Historically it hasn't been with examples where address size was bigger or smaller than the "bitness" of the CPU. Look at 8 bit CPUs like the 6502 & Z80 that addressed 64KiB. The 16 bit 8086 addressed 20 bits and the 16 bit 80286 24 bits. On the flip side, the 32 bit ...

Some great tips and advise above, love the paper towel tube idea. Just adding that a common fault on an aged system is the capacitors going, they have a defined lifetime after which they break down.

Without wishing to offend you, have you checked and triple checked that the CPU fan is connected to the primary CPU fan connector and not a secondary optional connector? I only suggest this as I've made this mistake a number of times when the motherboard hasn't had it clearly marked.

The memory controller doesn't appear to support high-density modules with more than 1 GB per rank with the processor installed on your system. The 2 GB Hynix module is a dual-rank (double-sided) module. This means that each rank has 1 GB of memory. However, the other modules you tested (Kingston 2 GB single-rank, ADATA 4 GB dual-rank) have 2 GB per rank. ...

The key point that other answers are missing is that yes, a fast CPU has more silicon/transistors than a slow one, BUT - that implies more overhead even when they're not in use. Dialing down the clock speed can help, but there is a minimum to just keep things running at all. Analogously, a large car engine may have more power than a smaller one, and in turn ...

You can, power options in the OS can reduce minimum clock, I've seen 4th gen i5's clocked to 800Mhz by windows power plans and consuming tiny amounts of power. The downside to this is current gen CPUs take a nonzero amount of time to respond to increased workloads so when the processing power is needed users can experience a "lag" before they clock back ...

The short answer is this: To do a certain amount of work requires a certain number of transistors to change state. Doing work at a higher rate means more transistors changing state per second. It takes a certain amount of energy to change a transistor's state and effectively, all of this energy winds up being dissipated as heat. So doing work faster means ...

OK, I just saw the same symptoms on a recently updated MacBook Pro 13" (2015 edition so the latest hardware). I updated to El Capitan and sometime soon after started noticing the slowness issue.
