True, there are very few programs (and even fewer games) that can take advantage of 2GB of RAM. But they are out there. I believe the 2GB will help when there's too much data/textures being shifted about and the GPU framebuffer is exhausted.

Of course. Noob error there. I must have mixed things up.

So, any specific issues with 512x4 on an AI7 I should know about ? I'm running 512x2 now.

I concur. There is simply no need to turn it off (from what I've read anyway).

I shouldn't see why not. It gets detected as a normal hard drive right ? So you can probably set the pagefile to use that drive.

Well i just took the plunge today, and I can already see the benefits in BF2.
I'll experiment more on Doom 3, Vista, DoW:WA and Half Life 2.
No 1Gb vs 2Gb benchmarks, just my personal observations.

Well, I've just redownloaded the FEAR SP demo, will test it later tonight. I experienced the "turn-into-a-corner-and-stutter" syndrome running on 1GB last time. Let's see if 2GB helps. Will also check out how Vista CTP performs.

Ok,

FEAR SP demo
The 1/2 sec stops are still there. BUT, overall it feels soooooo much smoother. The "stutters" occur in some corners (not all, and not in a stutter, ok, stutter, again fashion.), and though while they do distract a bit, the overall gameplay experience is still solid.
Verdict: Noticeable improvement over 1 GB.

Vista CTP
It still lags, but lags less compared to 1GB. Responsiveness seems/feels to have gone up as well. One explorer window, 2 IE windows, task manager running, shows 630MB+ of memory usage (this is with Aero Glass).
Verdict: Too early to tell, responsiveness seems up, but in the end the 2Gigs should definately help.

My pagefile is set to 100Mb (Min/Max).

Sure, no harm trying. I'll let you know later tonight. Though from what I've read performance benefits (if any) are negligible.

Update (1.50am) : Nope. No performance gains.

Mac,

This guy managed to run 4x512MB sticks.

memmaker 6. I had to free up 630k just for Falcon 3.0.

*It's getting off topic*,

Not 3 biji,

1.5 GB = 2 x 512 + 2 x 256
2 GB = 4 x 512

Depends on your usage patterns. It might make loading (of certain programmes and games) faster, but generally if you don't make use of a program (or programmes) that can make use of the RAM, i.e like multi-tasking for example; you won't be seeing much of a difference.

Again, depends on the application type. If the application is memory hungry and not cpu-bound, you''ll see the difference. *Generally*, you should still see some improvement.

Hence the "If's and Generally" statements.

Provided they're both of the same type (double sided, etc) they should work.
Previously running 1GB @ 512 KVR + 512 Corsair VS, dual channel on my Abit AI7
Now it's 2GB @ KVR + CVS & KVR + KVR

Well, if you compare purely in terms of numerical value, yes, Vista does require quite a bit of RAM. IE 7+, 6 tabs, sidebar on Vista Beta 2 (untweaked) eats up 748Mb of RAM.
2 Gb will be the norm soon, and prices will soon reflect that. It's all a sign of the times (moving ahead) really.

Quantity will win over quality in this case.

If i am not mistaken, it should still work with 4 DIMM Slots:

Channel 1 = Dimm 1 + Dimm 3 = 512MB + 512MB
Channel 2 = Dimm 2 + Dimm 4 = 1GB + 1GB

Total RAM = 3GB.
