Memory not showing dual channel?

I didnt.

and i'm only suggesting that match pairs guarantee compatability, i have always been under the impression that the two sticks of RAM have to be as similar as say... a crossfire or sli setup with two of the same card. There are no dual channels sticks... its right that the mobo enables this, still needs the identical RAM though to work.

EDIT:

Fitting to a Deluxe model, ASUS A8N32-SLI Deluxe functionality is exhaustive. We can complain only about having to install some ports on the front panel, as the rear panel cannot accommodate all connectors. Memory slots are divided by channels in a relatively rare way: to enable dual channel mode, two memory modules should be installed into next but one slots, not into neighboring slots (it's good for ventilation they say). If you by any chance install both memory modules into the slots of the same channel, the motherboard will no start up — this mode is not supported, which is noted in the documentation.

Is that what you mean? http://www.digit-life.com/articles2/mainboard/asus-a8n32-sli-deluxe-nforce4slix16.html

The idiot thing was regarding some posts further up. And you don't need matched pair RAM for dual channel to work.

Edit: Sort of, yeah. I installed the RAM into both the blue slots in that picture, but dual channel won't work. I think what they mean about memory in the same channel, is if you put a stick in the blue and black slots right next to each other.

but they need to be the same... as in speed etc yeah?

Yes.

Foehammer2003 · 30 May 2006 at 14:22

hmmm... well if it was me i'd always buy matched pairs... just as they are guaranteed to be compatible, whether im just buying into speil remains to be proved either way i guess. If i am wrong (very possible lol) then i wont be buying matched pairs on that basis in future.

What RAM are you using?

Could you post the numbers on each RAM stick sticker?

Crucial Ballistix PC4000 1GB

Is that the same on both sticks?

Clown · 30 May 2006 at 18:03

Probably not. I'm not getting it out of the case just yet

monkeypants · 30 May 2006 at 18:24

Personally I can't think of anything without knowing the numbers on each stick. Post them when you get them out.

Clown · 30 May 2006 at 19:25

Is it worth getting my dual channel to work? Single channel can't be that slower?

Foehammer2003 · 30 May 2006 at 20:44

Depends on your chipset to a certain degree aswell, but check out the link for a nForce2 comparison for the two standards... i think its well worth it. But you decide if its worthwhile for you

Yes I was, but anyone else who has problems can post the serial numbers too.

Clown · 31 May 2006 at 20:10

I just had a look and both my sticks have the same stickers.
What does this mean? Also, neither of them will run in dual channel mode now (on their own). Is it the RAM or the motherboard's fault?

monkeypants · 31 May 2006 at 20:14

You must have both sticks in to run dual channel.

Clown · 31 May 2006 at 21:36

Won't boot with them in the dual channel slots.
1+3

monkeypants · 31 May 2006 at 21:56

Have you run memtest on each stick?

If you get no errors for about 10 passes then the motherboard is pooed.

kmistry · 1 Jun 2006 at 10:11

wicked thanks a lot dude, i will run memtest on the sticks and post back! only weird thing is the RAM does show up as 1024, just not dual channel, so i thought the mobo would be ok, but anyway thanks

Serial numbers won't make a difference from my own experience. Upgraded to Socket 939 awhile back & ordered the exact same number stick from Crucial to match a 512MB stick I already had & they could not work at all in Dual Channel Mode. Crucial told me I have to order a pair of sticks which they themselves have certified as matched!

& whateva you think, Single channel sucks - Dual is what makes A64 fly & the benchmarks are there to prove it (especially the huge performance gap between the 2) :cool:
