32-bit vs 64-bit

I'm building a new computer to run newest games at least moderately and I need to decide whether I take 32-bit or 64-bit windows 7.

I already know some of the pros and cons of both systems. 32-bit can't have more than 3gb RAM, 64-bit doesn't have this problem but some programs don't work on it or have weird bugs and it generally just isn't as stable as 32-bit.

Which one you prefer? Is the 3gb RAM limit worse than the cons of 64-bit?

Perfect solution would be some way to have atleast 4gb RAM with 32-bit, but I don't believe that is possible.

64 bit is absolutely fine if you get Windows 7 64 bit. I recommend it, as long as your processor supports 64 bit.

Wait... I got 4 gb ram and 32-bit. IT'S A CONSPIRACY!

Anyway, 64-bit is better, though some programs does not have a version for it.

it is impossible to use the last 1gb as ram (32 bit = 2^32 is the max amount of ram that can be allocated, as that is how big the address is), but you can use it as a ramdrive (virtual hard drive) that would be ridiculously fast.. not too many applications outside of a Photoshop scratch disk for only 1gb tho

what programs are you worried won't work on x64? x64 has a built-in compatibility mode for non-64 programs that works with just about everything

@ azareus - yes you can have that much ram in the computer, only the last chunk of it simply won't be useable as ram

I run on Windows 7 64 bit and I have found no problems with program compatability.

Don't start making up numbers when it comes to 32 bit max memory supported. 1GB is assuming he has a 1GB video card. You can use 4GB total with 32 bit, including your graphics card memory. So if your graphics card uses 512MB of memory you can use up to 3.5GB regular RAM.

Video card RAM doesn't affect motherboard RAM. So no, if you have 512mb of video card RAM and 4 GB of motherboard RAM, you will have 4gb of usuable RAM for the OS.

no, codemonkey is right - they do use the same, it was my bad for assuming 1gb for the graphics card, but regardless, you will use some amount of ram for graphics (and 1gb is pretty common these days, especially if you want something to run the newer games moderately), which you will then have to subtract to get your available system ram

And where are you getting this info? I think you're confusing it with when integrated chips use system RAM as videoRAM.

    Signatures can be edit in your account profile. As for the old stuffs, I'm thinking it's because Blizzard is now under Microsoft, and because of Microsoft Xbox going the way it is, it's dreadful.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
