Yeah I've been looking around on the internet and stumbled across something saying that 4Gb of RAM will not function well on a 32-Bit OS like XP. Is this true? and as a second question, as I'm looking to buy something with 4Gb of RAM how does a 64-Bit OS affect gaming and other things?
Yes, it's true. I didn't know this when I bought 4 gigs of ram for my XP machine. It only recognizes 3.25 gigs of memory :( I don't know if it's worth going to a 64 bit OS just to utilize all 4 gigs? anyone?
As already stated you won't be able to use all 4GB, but you still benefit from the majority of the RAM. It won't cause system instability or anything like that.
Like Bs|Archaon said, you can have 4 GB of RAM on your OS. But because of userspace limitations on a 32-bit system, you simply don't get the full benefits of 4 GB of RAM.
If you had a 64 OS, your PC would function much more like it has 4 GB.
Is this at all related to the FF mod?
To my knowledge windows XP 32-bit only uses around 3 GB or 3.25 GB of RAM but if you go for Vista home premium 64-bit I think you could upgrade your system to 16GB of RAM, or even beyond well if your motherboard is capable of handling it oh and don't forget, if you go for vista you definitely need to 1.5GB for your operating system
On the game in question 4 GB of RAM. I find it's a must, definitely if you want to play in future games when they come out crisis already uses 2 GB of RAM and face it the gaming industry doesn't sit still
when I build my new system. I'm going to use dual-boot vista64bit and XP32bit just so will be able to play older games. There are some games that conflict with vista 64-bit
I hope this helps you a bit oh here's a site where you can check if the computers able to run certain games could be useful in the future Can You RUN It?
A 32-bit OS can use exactly 4096MB of RAM, but everything on the motherboard gets first picks of the RAM before the actual RAM modules themselvs; they get what's left over, usualy about 3GB. A 64-bit OS doesn't have this problem - it's limited to 128GB.
Its semi true. 32Bit OS can actually support the full 4GB easily, you need to do a registry edit to remove the physical memory addressing, I did it and it works great. MS added it in for some reason
@Daedalus 64bit is actualy alot great limit then that, its actually 16 EXABYTES of Ram...
The emergence of the 64-bit architecture effectively increases the memory ceiling to 264 addresses, equivalent to approximately 17.2 billion gigabytes, 16.8 million terabytes, or 16 exabytes of RAM
Thanks Pilla. I'll try that if I get a chance. But I could however, if I get a 64-OS, replace it with more RAM, possibly 8Gb (4x2Gb).
