Is it possible to downclock the cpu?

Does anyone know of any software available to let me run the cpu at a slower clock speed? When I'm going to leave the computer on overnight with a task running I'd prefer the cpu run a little cooler and not have the fans spin up to take-off speed.
I've tried using the CHUD tools to turn off one of the cores, but encountered some kernel panics.
Thanks

Here is the easiest way and requires nothing extra. It cuts the speed in half.

Is it possible to upgrade the CPU on an MSI GX-730 laptop?

Hi. I was wondering if anyone knew if it was possible to upgrade the CPU on an MSI GX-730 Laptop with an X2 Turion CPU currently in it? And if it's possible, what other CPUs are compatable? I was hoping to put in a Phenom mobile processor, but I am not sure if one would work in it. Thanks.

The short answer is no, you cannot upgrade it.
The long answer is you might be able to upgrade it to a slightly better Turion, but I'm not really sure it will provide any benefit.

Is it possible to upgrade the CPU or GPU of a Toshiba Notebook?

Many customers would like to upgrade/replace the CPU (Central Processing Unit) and/or GPU (Graphics Processing Unit) in their mobile systems to gain performance.
Toshiba does not support or recommend performing modifications on their mobile systems since the core components in these mobile systems are not upgradeable like in a desktop system.

Hi there,
I think what John meant to say is: it is not possible because it´s too expensive and you won´t gain some really big speed. I don´t know where you read something, but I think if you were a toshiba technician and would be familiar with electronics and the machines or especially with your machine than you won´t have a problem to exchange it.
I already tried to perform such exchange on my Satellite P20 some months ago. I can truly tell you: it didn´t bring me really some speed or performance. You will gain more performance by upgrading your RAM or your harddisk, but not with exchanging your CPU.
And it doesn´t matter which machine do you have regardless if you own a Satellite, Satellite Pro or a Tecra. The result is the same because the models have all the same componentes (but not similar hardware :) )

Satellite P100-119: Is it possible to upgrade the CPU to Duo Core?

Ive a Satellite P100-119 Notebook with 1,66Ghz (Duo Core). Is it possible to install a faster CPU (2,0 Ghz Duo Core) in this Notebook, without exchanging the Mainboard?

Yep, that's theorically possible. Both CPUs fit in the same physical 479Y socket, and today's BIOSes are smart enough to check the CPU speed.
However, if you're gonna do this by yourself, have lots of care when disassembling your laptop, and keep in mind that it may void the warranty. Keep in mind that you risk turning your laptop into a useless heap of junk if anything goes wrong (e.g. bad dissasembly or bad use of thermal grease). I repeat: be extra careful if you're replacing the CPU by yourself. Go to a service partner if in doubt.

Possible to replace the CPU on Satellite A200-1H2?

Can i replace my cpu (Toshiba Satellite A200-1H2) with another one? Cause i know some laptops can do that.

Hi mate,
first of all, if you want to loose your warranty then replace it. And I could give you 10 more arguments why not do it because if youre not familiar with disassembling notebooks and without information about the machines hardware you cannot exchange it.
So, generally its NOT possible, maybe with another brands but I think the manufacturers of another brands do the same like toshiba and will revocate the warranty of the machine if you open your machine and attempt to modify the "hardwired" hardware inside of your notebook.

Unsticking the CPU

hi
i was just wondering,
when u buy a new CPU (3E prescott) , you have the hard glue stuff on the bottom of the Heat sink, what i want to know is once you have stuck the CPU to the heatsink and installed it into its bracket, is it possible to take the CPU off?
is it possible? if so how do u go about getting it off? it seems to me its a permanent thing, not like i was going to take the CPU off anyways, i just wanted to know.
thanks

nope, its not really supposed to be that sticky...
basically, what that does... its a thermal pad, and once you install the cpu, and power the system up, the heat from the CPU will melt the pad onto the chip, providing decent connection (heat transfer) between the HS and the CPU...
you can definitely take the HS off later if you want... keep in mind that stuff has melted on there, so you gotta be careful not to yank the chip out of the socket.. (if you did.... not really something to cry about, just try not too)
its not permanent in any way... what most people do is actually remove that black thermal pad, and use a high performance thermal compound, like Arctic Silver 5, it contains micronized silver, and can aid in the heat transfer between HS and CPU better than that thermal pad...
rest assured, if you ever wanted to take your CPU out, or upgrade to Arctic Silver 5... it wouldn't be a problem

Is it possible to make an upgrade on the CPU ?

As the new iMac is using the same type of CPU of intel PC, can I brought a higher clock speed CPU and replace it after my warranty is passed ?

Since the CPU in the iMac Core Duo isn't soldered onto the logic board you might be able to do it in the future. No idea about what type or how much faster a CPU you might be able to install since the iMac has a cooling system designed for the 1.83 or 2.0 Core Duo. Will be very interesting to see what is possible.

Is it possible to replace (not upgrade, just replace) the CPU in my hp pavilion d6-2164ca?

And if it is possible, is it even worth doing?My computer has decided to give me the common problem of not starting up. At first the blinks (no sound) indicated a BIOS issue, but when I attempted to flash the BIOS it didn't work and the LED code changed to a CPU issue instead. I've been told that it isn't likely to be a motherboard issue, but if I did replace the whole motherboard would that replace the CPU as well?
PLEASE HELP! I really need my computer back!
Thank you!

Yes the CPU is socketed and replaceable. However, I have only seen one or two bad processors and dozens if not hundreds of bad motherboards. Usually if you buy a motherboard it does not come with the processor and you swap your old one over. Sometimes on eBay somebody will be selling a combination motherboard and processor. The problem is the Turion M660 is very hard to find for sale. I could not find one online at all to even tell you what the price may be. The M600 is pretty cheap at $33:
http://www.ebay.com/itm/AMD-Mobile-Turion-II-Ultra-Dual-Core-M600-2-4GHz-2M-s1-TMM600DBO23GQ-/150895...
The M600 should work and you would give up a couple ticks of processor speed only.

MSI Big Bang-XPower II More MB RAM than the CPU can handle...

I understand reading in a few forum post :" By making more memory available to the system more data can be cached in RAM, so there will be less hard drive activity, and less swapping to memory so your system will perform better." But what happen when motherboard for a desktop that supports( and had install) more RAM than the processor can handle?(aka:processor Max Memory Size).
Please comment in this configuration.as I 'm looking for a MB than offer me the more SATA6 connection i found a few available using LGA2011 socket (MSI Big Bang-XPower II LGA 2011 Intel X79 SATA 6GB/s USB 3.0 XL ATX Intel Motherboard with UEFI BIOS) than support 128GB. As I understand the processor Intel® Core™ i7-3930K Processor only work with 64GB.
Is there any advantage to have a MB that hold a bigger RAM capacity than the CPU? If so, how can this be translate using in a program like Adobe After Effects, RAM preview? thank

More Memory doe's not make it faster as its Volatile Memory (more RAM but it has to be run at much slower speeds) that is very short term and is just a buffer for active Programs and files it Caches there while its active but in no way improves system speed (as it has to be clocked slower to allow the IMC on the CPU to cope with it)! more memory just allows more Active Large programs and files open at the same time and huge amount of ram will only really be of benefit for things like Video Editing, photo editing and 3D rendering as those take alot of ram to allow all the computations that the CPU does to be held for quick access but only when they are active!
having more RAM then your CPU can Handel is a VERY BAD IDEA as it will just refuse to even post or in very rare cases damage the CPU's IMC leading to a dead CPU!
why MSI have done that is for possible later 2011 CPU's that may allow the 128GB of RAM limit to be used but currently they do not exist currently as X79 is a more professional grade Platform that will probably be around for years to come (may be used for many upgrade cycles and may eventually have a cpu that can use 128GB or ram) and who knows what will happen with Intel CPU's in that time frame! (more of a possible forward compatibility thing as its a very high end platform)
as for after effects it uses RAM for holding Render Files so in theory more ram will just allow it to render Larger files that are more complex without hitting the Available Ram ceiling that your computer has but it will not render any faster as a result it just gives it more headroom to work in!
so overall more ram = more Active space available & no increase in speed (actually maybe a drop in speed as it needs to run slower causing LAG/Latency) so it all depends what is important to you here to whether more ram is of any benefit or just a hindrance but that is down to your own use case scenario!

What is Apple's stand regarding OWC offering to exchange the CPU in a new MacPro 2013?

I thought to have already put this question here a short time ago.
However I cannot find it for reasons I do not understand.
Therefore here a second try.
Since a couple of days OWC is offering to swap the CPU of a new ("End 2013") Mac Pro.
They pretend their CPUs are more powerful and less expensive.
They quote the "Magnuson Moss Warranty Act" which in the USA states that a manufacturer cannot force his customers to use only the replacement parts he sells.
In their view therefore Apple could not legally void the 1 year limited coverage or the 3 year Apple Care coverage because a third party (OWC) modifies a Mac Pro.
On the other side the only "user replaceable" part in a new MacPro End 2013 according to Apple and mentioned as such in their owners manual is RAM.
While OWC says that the exchange of the CPU is performed by "highly skilled Apple technicians", even if we accept this, those technicians are not doing it in the name and as employees of Apple but working for OWC.
Therefore, either Apple approves and agrees with the changes OWC makes to their new MacPros, in which case the customer will continue to enjoy full Apple support to the so modified machine, or such a step isn't at all done with Apple's blessing and voids every coverage by Apple.
I am therefore waiting for a urgently needed clarification of this matter by Apple.
If any such third part modification of an Apple product voids all commitments of Apple to the owner of that piece of equipment, people should be warned in time before taking any risk of that kind.
However until now I find no statement whatsoever coming from Apple, either approving such measures or disapproving them entirely.
Strangely OWC pretends to deliver by themselves full coverage to a modified computer and not only regarding the CPU they exchanged but the ENTIRE MacPro!
Should that be true, then why mention the "Magnuson Moss Warranty Act" to prove that Apple CANNOT legally refuse coverage to a computer they modify?
The second point difficult to understand is that such an entire coverage of a modified MacPro would mean being able to replace if necessary ANY PART in one of these new machines, something only possible if Apple delivers to OWC whatever they need.
I hardly believe that they could get by themselves any and every part of such a new computer bypassing Apple.
Surely Apple has exclusive agreements with the suppliers of at least most of the parts needed to assemble a new MacPro.
I believe that a clear statement of Apple regarding this matter should be made and the sooner the better!

Apple has not made any public statement that I've seen, and won't do so here, these being user-to-user support forums.
While OWC says that the exchange of the CPU is performed by "highly skilled Apple technicians", even if we accept this, those technicians are not doing it in the name and as employees of Apple but working for OWC.
That would correct. The technicians may be certified by Apple for doing Mac repairs, but the technicians will not be Apple employees.
The second point difficult to understand is that such an entire coverage of a modified MacPro would mean being able to replace if necessary ANY PART in one of these new machines, something only possible if Apple delivers to OWC whatever they need.
I hardly believe that they could get by themselves any and every part of such a new computer bypassing Apple.
Surely Apple has exclusive agreements with the suppliers of at least most of the parts needed to assemble a new MacPro.
OWC is not using any Apple-provided parts. They are getting processors from other suppliers.
The normal legal stance, at least in the US, is that a manufacturer cannot refuse warranty service due to a third-party or user modification unless that modification can be shown to have led to the problem. So whether Apple would refuse or accept warranty on a modified Mac Pro would depend entirely on what the problem is, but this is what OWC is referring to.
I very much doubt that Apple will make any statement on the issue other than to direct the user to the official warranty statement. For the US, see:
http://www.apple.com/legal/warranty/products/embedded-mac-warranty-us.html
but if they do choose to make a statement, it will not be here in these forums.

Satellite C650-1CP - Is it possible to upgrade the GPU?

Hi
I just wanted to ask a question about my graphics card in regards to gaming.
I just recently found out that integrated graphics chips arent that good for gaming so i done a little reading into the subject and found something saying that there is a possibility that you can send the laptop to the manufacturer and purchase a chip upgrade or pay to get a better one installed.
Is this possible? and if it is, what sort of price would you be looking at. My laptop is a C650-1CP as i said in the title.
Thanks

Hi
No, this is definitely not possible.
There are plenty of threads about this theme and GPU (graphic card) upgrade is definitely NOT possible.

How do I measure the CPU/GPU split of load/usage in Java3D?

Hello,
Is it possible to measure the split between graphics and CPU usage to find out how much work each is doing, what work is done, and which is doing the most work, for example? If so, how can this be implemented in the Java3D code?
For example, on a particular system, measure whether the GPU is doing the most work, or the CPU.
Thanks for your help :)

In Linux, you can read /proc/uptime. It does NOT give you the load averages that the command uptime gives. It gives you numerically the amount of time the CPU was idle vs how much time it was spent doing something. You need to read these two floating point numbers one every second, or once every 5 or 10 seconds then do the delta on the change: The maths are as follows:
Read the file in twice in 5 seconds, parse into two floats/doubles:
double[] last; // the first read of the file
double[] rect; // the latest read of the file
double ld = last[1] - last[0];
double rd = rect[1] - rect[0];
double cpu = (1.0d-(rd/ld)) * 100.0d;This should print the CPU percentage in Linux for that given time frame (5 second updates).

Is it possible to downclock the cpu?
