Quick Q about Dual DDR NF7-S 1.2

[bertie]

Got 2x256mb pc2700.
Just need an answer as to which two slots i should have them in on this motherboard?
I read somewhere when i bought it that the manual was wrong..

[luke313]

Either in slots 1 & 3, or 2 & 3. Simple as.

yup

Remember to sync your RAM to the CPUs FSB, so they are both on 166mhz at the minimum

[bertie]

So it can be either 1 + 3 or 2 + 3..
I had mine running in 1 + 2!

Is there any way to know if it's actually running in dual ddr mode, in the bios or anything?

Get the latest BIOS and it'll say "Dual DDR activated" in POST to tell you it is

[bloo_fish]

Not that it will make much difference but...........
The Abit NF7-S manual says for dual ddr dimm1 & dimm3, or dimm2 & dimm3.

but then the latest bios says for dual ddr its best to use dimm2 & dimm3.

So i'd go for dimm2 & dimm3.

Thanks guys - to think i've been missing out on this added performance for so long

What does this mean exactly? If I'm running my XP1700/133 CPU at 200 x 11 then the CPU is running at 200 FSB and DDR at 400, right?

You can have your memory and CPU run at different FSB speeds.
Say your AMD processor was running on a 133 bus, but your RAM could do 200, then you could run it like that using whats called dividers. The problem is, with AMD systems you usually get a decrease in performance because of this, its best to have your ram 'synced' ie, the ram FSB and the CPU FSB running at the same speeds, it offers a huge performance boost

i think abit like you to use 2&3
im sure ive read that somewhere

Yup, they recomend you start at slot 3 and work to slot 1

[steve threlfall]

remember tho nf7 slots were marked up wrong. Slot one is actually slot three for some reason!!

Anyway there are two memory slots together and one alone. Put one stick in the solitary bank of slots and the other in the other bank (whichever slot in that banks fine- doesnt matter)

Yup got it now - I was confused when I bought it by the mislabelling.
Got the Dual DDR thingy in POST now
Thx again

You mean the Divider which I've set to 3/3, that's right is it?

Thats in sync

x/x will mean its allways in syc.. 1/1..2/2...3/3... are all in sync
Ive found 6/6 to be best for overclocking, although there is no logical reason for this
