RAM upgrade: 18GB limitation (win 7 home premium))

[vhein]

Hi all,

i'm thinking to add more ram to my current built:
intel 920 with Asus P6t-SE
currently it has 6GB 1066mhz RAM (3x2GB) running triple channel

now in my understanding, windows 7 Home Premium will not be able to support more than 18GB RAM

and so i would like to get your opinion on which RAM setup should i go with?
1. get another 3x2GB 1066mhz (to make total 12GB)

2. Replace with 12GB 1333mhz (triple channel)

3. Replace with 20GB 1600mhz (5x4GB)
http://www.scorptec.com.au/computer/...600c9d3k6/24gx

my concerns is more on performance from:
(i) the move from 1066mhz to 1600 will make any difference.
(ii) triple channel 12GB (6x2GB) vs 24GB (5x4GB)

I will be using this primarily for Photoshop

thank you all

1333 is where you will see a good difference, anything after that the jump from your 1000 won't be as noticeable.

G'day

Limit is actually 16GB for professional 7 X64 unless you upgrade to a higher version in which case it then becomes 192GB.

Actually the limit is
Windows 7 home premium 16Gb
Windows 7 Professional 196Gb.

Home premium is going to be limiting. You will have to upgrade the OS or hack it to get more than 16gb.

so your looking for 3 sticks or 6 at 1.5volts at 1600 10-10-10-30 or so

dont get 1.65v ram(old stuff)
+ some older mboards dont like 1.25v ram(to low to set in bios)

looks like scorptec only stock old models or tripple ram kits.

you can use dual/quad channel kits in board..(keep it 1.5v xms 1.2-1.3)
for dual kit you need 3 kits(6 sticks), or buy quad kit + does use 1 stick(3 only)
