32-bit XP and more than 2gb RAM

I always thought that with the above, more than 2gb is POINTLESS. But someone on here recently said that wasn't the case. Now, I know it's never going to recognise the full 4gb, but would you see ANY performance increase at all moving from 2gb to 4gb RAM on XP 32-bit?

It will see about 3 gig, so yeah there will be a perfomance increase - ie another gig of ram.

I'm using 4gb in a vista 32 system. Bought cos a pair of sticks was uber cheap.

yes, as you will be moving form 2GB to 3 ish, I cant remember what the exactly 32bit limit is, but it includes anything that has memory, so that's GFX, RAID etc Cards

i think its 4gb - graphics ram - all caches - all other memory - 1 byte or something

Cheers - just one more thing...

I currently have 2gb of this:

OCZ 2GB (2x1GB) PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2 (OCZ2P800R22GK)

And am thinking of 4gb of this:

OCZ 4GB (2x2GB) PC2-6400C5 Dual Channel Vista Gold Series DDR2 (OCZ2G8004GK)

Just wondered what the difference was between the C4 and C5?

Timmings, the C4 is CAS4 and the C5 is CAS 5.

mcgriffo · 28 Mar 2008 at 16:00

So is it a no-brainer that CAS5 is better than CAS4 in the case of these two OCZ examples?

cas4 is better. lower timings mean lower latencies which translate in to marginally faster ram. its always better to go lower, but dont do so if it means your paying a premium because there isnt much of a difference
