xendrome Posted April 12, 2013 Share Posted April 12, 2013 I thought there was only "3.25gbs USEABLE" out of 4gbs in a 32bit system. Total addressable space is 4GB, that includes ROMs, video RAM, etc. So it depends on the system hardware config. ShareShiz 1 Share Link to comment Share on other sites More sharing options...
Xenomorph Posted April 12, 2013 Share Posted April 12, 2013 What year is this? The last time Microsoft released a 32-bit-only consumer OS was Windows XP, back in 2001. Twelve years ago. Everything released in the past several years or so has worked with 64-bit. Windows, Linux, and Mac OS X. matt4444 1 Share Link to comment Share on other sites More sharing options...
DrCheese Posted April 12, 2013 Share Posted April 12, 2013 dont know 32 bit is just generally more reliable and fast, did see some benchmarks to that effect.. Maybe back in 1994, but not in 2013. siah1214 1 Share Link to comment Share on other sites More sharing options...
Noir Angel Posted April 12, 2013 Share Posted April 12, 2013 Why would anyone still want to do this? All hardware that gets made is packaged with 64 bit drivers these days. It's far more stable than using PAE and with none of the annoying address space limitations. Link to comment Share on other sites More sharing options...
+Frank B. Subscriber² Posted April 12, 2013 Subscriber² Share Posted April 12, 2013 As others said - this is an entirely pointless exercise. If you want to use XP, fine. Don't expect it to support modern hardware or large amounts of RAM however. Link to comment Share on other sites More sharing options...

I can't believe that, though pretty much everyone has access to 64 bit clean software now, that you want to complicate your life with PAE. Embrace 64 bit and be done with it!

ViperAFK Posted April 12, 2013 Share Posted April 12, 2013 dont know 32 bit is just generally more reliable and fast, did see some benchmarks to that effect.. This is totally false. There are certain cases where 32 bit is a little faster and some where 64 bit is, but there's not really much difference, besides actually being able to use all your memory in 64-bit. Hanging on to XP/32 bit is ill advised, especially considering XP support is ending soon. I'd definitely recommend you upgrade to windows 7 or 8 64 bit....

n_K Posted April 13, 2013 Share Posted April 13, 2013 And there was a 64bit version of XP based on Windows 2003 Server. Very true, support for it was dropped pretty quick and it was withdrawn from sale. The only place I've ever seen is being used legally (not using pirated media/keys) was at uni. on some VMs for network security training. Link to comment Share on other sites More sharing options...

The_Decryptor Veteran Posted April 13, 2013 Veteran Share Posted April 13, 2013 At this point in time it'd be easier to just run each app in a separate XP VM and give it it's own dedicated 4GB RAM segment, you'd have less compatibility issues than patching the kernel to allow access to the extra memory PAE allows (32bit Windows already uses PAE for things like the NX bit, but disallows using it for memory because drivers and such suck, a situation which isn't going to improve due to how old XP is) Link to comment Share on other sites More sharing options...
slumdogtrillionaire Posted April 13, 2013 Author Share Posted April 13, 2013 PAE isn't worth it. I hade 4gb of ram on my XP machine too and I just dealed with it. If it's an issue, you can build a pretty cheap 64 bit pc. Windows XP x64 is a very nice OS, and I enjoyed useing it, that is, if your not up for upgradeing your OS. srsly ive got dreamspark premium and decent quadcore hardware. xp is still low overhead great compatibility no cleartype font mess snappy graphics os... besides ... if it would support >4gb why EVER move? Why does it matter? Windows XP is so old. shallowness is the moto these days?

The_Decryptor Veteran Posted April 13, 2013 Veteran Share Posted April 13, 2013 XP pre-dates multicore CPUs, it isn't optimised for them in the slightest (let alone low power/scaling stuff which CPUs do now). Newer versions of Windows make much better use of the underlying hardware (DWM offloads all desktop drawing to the GPU, Direct2D/DirectWrite offloads all application drawing to the GPU, etc.) articuno1au 1 Share Link to comment Share on other sites More sharing options...

Where are you getting that from? Aero uses the GPU, Luna does not. Here is everything you need regarding Windows, x86 and PAE: http://msdn.microsoft.com/en-us/library/windows/hardware/gg487512.aspx As I said before, you basically need to have 32-bit drivers that understand it and the application needs to be written for PAE to be able to use it properly.

spaceelf Posted April 13, 2013 Share Posted April 13, 2013 Core 2 Duo/Quad had slight performance issues with 64 bit as I recall. As far as I know they don't apply to any other architecture. Aero is most definitely not slower than Luna. Where are you getting that from? Aero uses the GPU, Luna does not. He's probably getting that from a crappy youtube video showing scrolling through hundreds of files in a directory going slower (though Vista and up probably show more detail in their icons which makes it an unreasonable and useless comparison, considering the only time an enduser would do something like it is approximately never.) Even if it was relevant, Direct2D alone makes XP seriously dated in display tech. Link to comment Share on other sites More sharing options...

pickytech Posted April 13, 2013 Share Posted April 13, 2013 Why bother looking for hacks that require paging in the OS? It's certainly possible that a 32-bit OS can access more than 32-bit's worth of RAM (4 GB) via paging, but there is definitely a performance hit in doing so. If you already have a 64-bit processor, then I see no reason to punish yourself with a 32-bit OS. To be clear, 32-bits represents 2 to 32nd power, 232, number of uniquely mappable addresses, which is 4294967296, better known as 4 giga[bytes]. Each address, in a modern processor, is a single byte, which is why the number of addresses equals the number of bytes. As pointed out by others, there are processor extensions that can enable further memory mapping, but similar to that being done for 16-bit processors, it was done as a stop-gap for those unable to get 64-bit processors. Besides, most consumer motherboards do not support more than 4 GB of RAM for 32-bit processors. And if you are going to buy a new motherboard, then you should definitely buy a 64-bit processor. dont know 32 bit is just generally more reliable and fast, did see some benchmarks to that effect.. This is unlikely considering that 64-bit processors have wider registers (64-bits) to push more data through the pipes. It should be the same or better.
