For example, on most 64bit platforms, an int / long will take up 8 bytes in memory rather than the 4 bytes commonly used on a 32bit platform). I fail to see how 8 bytes isn't more than 4 bytes; that would require violating some pretty fundamental mathematical laws. Are you a cop? NOThat's friendly. Play nicely please, and stick to the facts - if you post stuff that's blatantly incorrect, I will call you out on it. Noting how much you do this, and how much people trust your advice, I think that doing so is entirely reasonable. No it doesnt. You should change your name to (en.wikipedia.org) Don't get personal please - I won't take it kindly.	Erayd (23)
1160534	2010-12-11 03:37:00	For what it's worth (and noting OP is interested in video editing) I installed Adobe Premiere Pro 2 in Win7 64bit. Adobe says Premiere prior to (CS4?) is not supported in Win7, let alone 64bit Win7. But it works. The only problem I've come across is normalising long sound tracks. Crashes the system. So I just unlink the sound track and chop it into 10min segments. Works fine	BBCmicro (15761)
1160535	2010-12-11 04:39:00	Just as a comparison -- to see, regarding the two kids fighting over 64 /32 RAM usage :p I have just done a real,simple basic test. Installed a copy of W7 Home Pre x86 & x64 from images I have , rebooting it twice, opened task manager, let it sit idle for 15 minutes (unplugging the ethernet connection after doing the image), taking a note of the Memory being used. Wiping the drive between installs. First 32bit then repeating with the 64 Bit. Result: Memory usage 32bit = 530MB 64bit = 605MB. (less than 100 MB) So while 64 does use a bit more, the actual amount is hardly noticable. :) So stop fighting or I'll set SWMBO on to you both, :p and shes running around with a bloody meat cleaver at the moment looking to chop something :lol:	wainuitech (129)

Actual differences generally depend on the type of app, and what that app is doing - raw data buffers don't generally make any difference, but the way that data is manipulated and the internal logic of the app does (the efficiency of the compiler also makes a difference). Regardless, the difference is - as you found - small.	Erayd (23)
1160537	2010-12-11 05:04:00	One thing that I did find interesting, as mentioned both times the PC was disconnected from the LAN (no updates etc) -- sitting idle with the 32bit, the CPU usage was next to nothing 0-5 % BUT with the 64 bit there was continuous usage even after 15 minutes, of 10 -30% average, sometimes spiking to 60% :confused:	wainuitech (129)
1160538	2010-12-11 05:10:00	Hi guys - I am the initiator of this 'colourful' and interesting thread. I have learned a few things so thanks for all the info. I guess what I will do is to install Win7 as 64 bit, and if I run into problems running programs I will then make an image, wipe the drive and go 32 bit. But if the speed of 64 is significantly better during video and sound editing, I will probably stick with 64. In any case, I will go for 8 G of RAM so 64 bit can fly, but that is another topic on my other thread...	Strommer (42)
1160539	2010-12-11 07:30:00	Gosh guys. No it doesnt. You should change your name to (en.wikipedia.org) Speedy, rather than resort to insults as a reply, maybe counter-post with your evidence if you want dispute what Erayd has stated. Play nicely please, and stick to the facts - if you post stuff that's blatantly incorrect, I will call you out on it. Noting how much you do this, and how much people trust your advice, I think that doing so is entirely reasonable.Erayd, that is a minor thing to quibble over when you say yourself the difference in memory is small.

1160540	2010-12-11 07:48:00	Yours is a 2 bit opinion Billy 8-{) :annoyed: Outrageous as it may be that 2 bit opinion may be useful for something one day. Keep it like all the others things you know you will never use... until you throw it out, then you find out you REALLY need it	The Error Guy (14052)
1160541	2010-12-11 07:57:00	Jen This was Speedy's direct reply No 64 bit doesnt require more ram I second Erayd's reply - 64b does use more RAM - it is minor, but it does use more. So Speedy's response was incorrect. I have used both (32 and 64b) so I speak from experience. Strommer - if your requirements (as you stated) include video re-encoding (or audio), 64b will definitely give you speed advantages. If you're just using it for mostly everyday tasks then you won't notice any noticeable difference. I've reverted back to 32b over the last 6 months (Linux) but am considering switching again to 64 for video, audio and compiling. Your requirements should dictate the environment to install.

1160542	2010-12-11 10:18:00	Erayd, that is a minor thing to quibble over when you say yourself the difference in memory is small.Point taken - Speedy, please accept my apologies for the excessively blunt correction, I could have been a bit nicer there. One thing that I did find interesting, as mentioned both times the PC was disconnected from the LAN (no updates etc) -- sitting idle with the 32bit, the CPU usage was next to nothing 0-5 % BUT with the 64 bit there was continuous usage even after 15 minutes, of 10 -30% average, sometimes spiking to 60% :confused:Now that is interesting, and I'd love to know why, as there's nothing I know of that should cause such a symptom.
