2x1gb + 2x2gb = 6gb 800Mhz will it work???

[DevilMind]

my rig:
Intel core 2 duo e8400 3ghz
HDD 500 gb SATA 2
VGA ATI 4670 512MB
Mobo Asus p5q-e
RAM ddr2 CORSAIR XMS2 2gb (2 x 1gb) dual channel

i already have:

DDR2 CORSAIR XMS2 1GB-6400/800 BUS (2 x 1gb dual channel)

Latency 5-5-5-18


i want to add :

DDR2 CORSAIR XMS2 2GB-6400/800 BUS (2 x 2gb dual channel)
Latency 5-5-5-18

This will make it :
Same Speed + Same Latency Memory + DIFFRENENT Memory Size

it will become 2gb + 4gb = 6gb ddr2 RAM

This is OK??

1) it should only be 2gb , 4gb or 8gb to work as dual channel ddr2 ???
2) will 6gb work perfectly with dual channel???

plz do help
thanks in Advance...

Yes this should be fine as long as matched pairs share the same coloured slots. 6GB should work in dual channel.

it might be fine but it wont improve performance so its a waste of time and money

How do you know she/he is not virtualizing or doing something else that could utilize the RAM (CAD/CAM)? ...and in that case it would not be a waste.

All the sudden THG's article means noone's got a use for anything above 4GB. Sheesh, I hope they don't say the moon's made out of cheese or some of you will be quoting that too.
