Hi,

 

Could someone tell me why the system properties is saying 4.00GB (3.19GB usable).  I am running windows 7 home premium 32 bit.  I would have thought if i have 4GB, the system would use 4GB.  

 

PS I don't know much about computers.

 

Thanks

You just explained why in your question.  A 32-bit operating system can not use a full 4GB of RAM.  Why did you install a 32-bit OS with that much memory?  I think your post is number 768 of the people that have asked this question.  

Sorry, I don't mean to beat you up.

thanks +devHead.  I had my pc made sometime ago and wasn't told it was pointless putting that much ram on a 32-bit OS system.  Thanks again for giving this info.  So, I am right in thinking the 32-bit OS system will only support no more than 3.19GB?

I think you can install the 64 bits version using the 32 bits license.

 

If i remember correctly i bought the 32 bits version of Vista and got the 64 bits cd later paying the cd only from ms web site. COuld be wrong that was a long time ago.

This.

 

Before you make a purchase that Hum suggested. Check your system to see if the hardware is 64bit with the checker at the following URL:

If your system is not 64bit, then you can not install 64bit OS on it but the installer will install 32bit instead.

32-bits of address space is limited to exactly 4 GB.

The problem is that the RAM is not the only thing that uses the address space. x86 (16, 32, 64) only has ONE address space. The first part of the address space is reserved for certain legacy functions as well as new standards. Devices with DMA function are directly mapped onto the space as well, such as graphics cards.

There is no fixed amount of address space that is used by RAM. If you add more devices that get mapped to the address space that you have, less RAM can be mapped onto that address space.

The amount of bytes that can fit into the address space is (bits^2)+1.

Why anybody would even contemplate installing the 32-bit version of Windows on a machine fully capable of 64-bit is beyond me.  Who built your computer for you? If it's a computer store, I'd be seriously questioning their competence right about now.

It's the other way around really, it's pointless putting a 32-bit OS on a machine with 4 GB of RAM and above.

Unfortunately it was a computer store.  They were recommended by someone.   Can't do anything about it now, its been about 4 year or so.

If you need the ISO this site has them.

 

2nd one down: Home Premium 64 bit.

 

IF THE KEY does not work call the Microsoft Activation # - Windows activation: (888) 571-2048

tell them it does not work with 64 bit they will give you a new one.

Actually, he should be able to crossgrade -  as long as the SKU (not the bitness) is identical, the key does not change.

Also, some PCs got hobbled due to BIOS quirks, despite being more than capable of swallowing 4+GB.

 

True story - my Mom's HP DC7600 (refurbished) came with 2 GB (eight DDR2 RAM slots) but has 5 GB onboard today.  The issues were twofold - when she bought it, four of the eight DIMM slots were populated with 512MB sticks (cheap), AND there was a BIOS bug which resulted in an address "hole" - which is why it came with XP32.  After updating the BIOS, I reinstalled Windows 7 x32 (which Mom's old PC was running), then crossgraded to 7 x64 (same key), and used the USMT to migrate her settings.  The crossgrade worked because she was also going to a larger HDD than her old one - a crossgrade requires an HDD the same size or larger.

    • Ocenaudio 3.19.5

      By Copernic · Posted

      Ocenaudio 3.19.5 by Razvan Serea  Ocenaudio is a full featured, fast and easy to use audio and music editor. It is the ideal software for people who need to edit and analyze audio files without complications. Ocenaudio also has powerful features that will please more advanced users. To assist ocenaudio development, a powerful toolset of audio editing, analysis and manipulation called Ocen Framework was created. ocenaudio is also based on Qt framework, a well known library for cross-platform development. Cross-platform support ocenaudio is available for all major operating systems: Microsoft Windows, Mac OS X and Linux. Native applications are generated for each platform from a common source, in order to achieve excelent performance and seamless integration with the operating system. All versions of ocenaudio have a uniform set of features and the same graphical interface, so the skills you learn in one platform can be used in the others. VST plugins support Ocenaudio supports VST (Virtual Studio Technology) plugins, giving its users access to numerous effects. Like the native effects, VST effects can use real-time preview to aide configuration. Real-time preview of effects Applying effects such as EQ, gain and filtering is an important part of audio editing. However, it is very tricky to get the desired result by adjusting the controls configuration alone: you must listen the processed audio. To ease the configuration of audio effects, ocenaudio has a real time preview feature: you hear the processed signal while adjusting the controls. The effect configuration window also includes a miniature view of the selected audio signal. You can navigate on this miniature view in the same way as you do on the main interface, selecting parts that interest you and listening to the effect result in real time. Multiselection for delicate editions To speed up complex audio files editing, ocenaudio includes multi-selection. With this amazing tool, you can simultaneously select different portions of an audio file and listen, edit or even apply an effect to them. For example, if you want to normalize only the excerpts of an interview where the interviewee is talking, just select them and apply the effect. Eficient edition of large files With ocenaudio, there is no limit to the length or the quantity of the audio files you can edit. Using an advanced memory management system, the application keeps your files open without wasting any of your computer's memory. Even in files several hours long, common editing operations such as copy, cut or paste happen almost instantly. Fully featured spectrogram Besides offering an incredible waveform view of your audio files, ocenaudio has a powerful and complete spectrogram view. In this view, you can analyze the spectral content of your audio signal with maximum clarity. Advanced users will be surprised to find that the spectrogram settings are applied in real time. The display is updated immediately when altering features such as the number of frequency bands, window type and size and dynamic range of the display. Ocenaudio 3.19.5 changelog: Fixes crashes related to audio devices on Windows (DirectSound and ASIO) Fixes several crashes and memory corruption issues Fixes opening several headerless files at once, which previously dropped all but one Improves batch export by suggesting and remembering the destination folder Fixes accented and non-Latin characters in VST plug-in and compressed-archive file names Adds zstd compression support and updates the archive library Other bug fixes and improvements Download: Ocenaudio 64-bit | Portable | ~40.0 MB (Freeware) Download: Ocenaudio for Linux and Mac OS View: Ocenaudio Homepage | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware

      I did think about a Echo show once and it would be useful to see what my cameras see. But my brother got one and I changed my mind. Adverts and not really worth the price just to see my cameras. I have a load of dots and a Echo Gen 4, they will do.

      I asking where you are from or live, because if you don't live in the U.K, why are you so bothered? That is another reason I voted out, E.U and people poking their noses in where they should not be. Sadly we still have it, Trump, and his cronies. Putin as well and no doubt others. It makes no difference what we believe, if we made the right choice or not, we are out. As I said to someone when the news first broke we have voted out, we just need to make the best of it. I have no problems with closer ties to the E.U, we still need to trade. Just don't want to be in their club.

      So you think I voted out because i am anti-immigrant. I am fed up with those that come over and think that we owe them something. The ones that are at the moment coming over from France where they are already in a safe country because they think and no doubt will get everything chucked at them. While people who were born and bred here get very little. I have nothing against as i have said before those that come here and work. In fact I know full well that our NHS would struggle without them. I do have a problem with those that come over here and try to push their religion and their way of life onto us. My reasons for voting out was because of what the E.U is and is also becoming. I did not agree with Freedom of movement, not because I don't want people over here, but because people need to be checked before being allowed to cross borders and that goes both ways. But my main thing was because the E.U is becoming if not already a united states of Europe. The only reason countries like Poland and Romania joined was because they had no money. When my partner left Poland, she had nothing, Poland had nothing, that is why she left. Wanted to learn something and earn a living. The E.U would have us back according to Michel Barnier. https://www.euronews.com/my-eu...ator-barnier-tells-euronews Why are you so scared to say what country you are in?
