Go for the 2 x 512 if you can - you have an upgrade path if you need one &
it will work.

it's VERY stable now with my 4 256 sticks but i just lose alittle on the
performance as opposed to 2 512 sticks

You should have used (2) 512MB sticks. It's much more stable in that
board,
and boards in general.

Hi, i've just bought an asus p4p800-d + p4 3.0C HT 800 + winxp and all
works
fine, though i have a question about my memory.

i have 2 of these kits :
Dual Channel Optimized DDR Kits - EL Platinum Edition
512MB (256MBx2) PC3200 DDR400 CAS2 (OCZ400512ELDCPE-K)




http://www.ocztechnology.com/product...0+Dual+Channel
+Platinum


= total = 1g

now if i install just 1 pair [for 512kb], doesn't matter which into
the
1st
2 blue slots, i can see the message on bootup saying " dual channel
400
mhz"
= so this is ok + i can turn the asus memory accel on with no problems
and
a
nice memory read increase according to aida32, something north of 4500
if
i
remember correctly, the write stays about the same with or without the
memory bios boost.

Now when i populate all 4 memory slots with the 2 kits [1g] on boot up
i
see =" dual channel 266 mhz" !!!! what happened to my 400 mhz????? +
when
i
try to enable the asus memory accel it says it can't boot and i have
to
disable it ????

Why is this happening when i use all 4 memory sticks? Anybody have
similiar
exp? thanks

ps. it's not a huge big deal, the write test is about the same speed
as
just
the 2 memory sticks themselves but the read test is just shy of 4000
if
remember correctly.

I'm thinking i should have just bought the 2 512kb kit and they would
have
worked at 400 = the memory boost, seems like the p4p800 is real picky
when
you populate all 4
