XP is not restricted to 2 GB.
XP can address up to 4GB, but usually mmio takes up around 500MB, so realistically you can get 3 - 3.5 GB of usuable memory.
More importantly if peak memory usage while running crysis does not exceed 2GB, then there is no benefit to having more than 2GB. Is anyone able to report typical memory usage for crysis?
Just get 4gb, RAM prices are extremely volatile and at the moment you can pick up 2x1Gb sticks for ~£32 which is about $64, eventually it will shoot up in price again so get it while it's cheap is what I say.
I'm just curious...why do you think there will be an increase in the price? Personally, I don't see why there would be.
That's just the way RAM prices have behaved over the past decade. It's like the stock market.
As I said recognizing and actually ...eas which are improved upon from the upgrade.

You will need to get a 64 bit OS to address more that 2 gigs of ram. Even if you can see all four gigs in 32 bit, it wont matter. XP32 bit is restricted to a 2 gig address for software to utilize.
Also don't forget that there is only a 2gb user space allocation for software which is why games like SupCom would crash out.
WRONG!!!!!!
soo wrong
a 32bit OS can only address 2^32 memory locations
From this hardware Must be addressed in a memory-map to expose to the CPU... NIC as a memory location, HD as a memory location....
once all the hardware as been mapped the remainder is avail to RAM and memory-mapped files. Ususally this would result in the machine being able to address ~3.8Gig of RAM BUT GFX cards with large amounts of RAM take alot of the addresses from that pool
The only way XP-32 would be limited to 2Gig of RAM was if you had a GFX card with 1.8Gig of memory which isn't likely.
Assuming the average for gamers is 512Meg of GFX memory, this leaves XP-32 (or ANY 32bit operating system for that matter, bar PAE magic) 3.4Gig to play with in address-space
Not on XP, that is something MS added to Vista
You can configure up to 3GB of address space for userland, but by default it is 2GB IIRC.Also don't forget that there is only a 2gb user space allocation for software which is why games like SupCom would crash out.
*patiently waiting for someone to actually BENCH 2 vs 4*
If I get 3 frames each for a Quad, 64 bit OS, and 4GB, I'm totally down.
Wait...
I'll be using XP.
Will that be a problem?
That's too bad. I was looking for an excuse to pick up an extra 2GB...As you can see, my average FPS in the Crysis Demo GPU benchmark actually decreased! I believe this is due to the way my motherboard handles 4x 1GB modules, though. If I don't enable the "Memory Remap" feature in the BIOS, I can only see around 3.3GB of RAM but the performance is exactly the same as it was with 2x 1GB. However, if I enable the "Memory Remap" feature, although I can now see all 4GB of RAM the performance decreases.
We are in the PC Gaming section , right? PC gaming and the limitations of the memory games use is what we are discussing, right?64bit versions of Windows(i.e. XP and Vista) do not suffer from the traditional 2GB barrier, as all the kernel mode addressing is usually moved to well above the confines of the limited 32bit addressing area.
