DualDDR Support

In an earlier revision of this review, I reported that ABIT's manual recommends that the DDR DIMM slots be filled in the order of DIMM3 to DIMM1. However, the information printed in that manual is wrong! Here's why.

NVIDIA's DualDDR technology relies on two separate memory controllers to double its memory bandwidth. There is a twist though. The first memory controller only controls the first DIMM slot while the second memory controller handles the last two DIMM slot. To enable DualDDR, you must use up two DIMM slots and one of them must be DIMM1. If you insert the two DIMMs in DIMM2 and DIMM3, you will be using only one of the nForce2's two memory controllers. That's why ABIT is wrong in recommending that the DIMM slots be populated in the reverse order of DIMM3 to DIMM1.

Now, it should be noted that it is not necessary for you to follow any particular order. I tried the following DIMM configurations - (DIMM1+DIMM2), (DIMM1+DIMM3), just DIMM1 and just DIMM2. They all worked fine so there shouldn't be a problem if you do not follow the recommended order. However, if you are using two DIMMs, make sure you insert one of them into DIMM1. The other can be in DIMM2 or DIMM3. Either way, DualDDR support will be enabled.

With that said, it's important to note that DualDDR isn't all it's made out to be. True, when enabled, it allows you to double the nForce2's memory bandwidth. However, due to the limitations of the AMD S2K bus, the processor won't be able to make use of that extra bandwidth. So, don't expect to see much benefit from DualDDR, unless you are using the onboard GeForce4 MX GPU of the nForce2 IGP north bridge (not used in the NF7-S). That's probably the only application that truly benefits from NVIDIA's DualDDR technology.

Warum ?

weil singlechannel einfach ned zählt :D

warum glaubst haben soviele fsb probs ? weil sie dual verwenden ?

ohne dual könnt ich auch ohne probs 200 fsb haben ...

aber normal müsste das abit 200 fsb ohne vdd v zugabe 200 mhz fsb machen tut es aber nicht zumindest ned bei mir und bei ein paar andern

Ich hatte 2*512 Corsair 3500er laufen.
1 GB hat sich ned auszahlt und deswegen reichen mir auch 512 single Channel.

Ich seh im Dual Channel keinerlei vorteile ....

Pass auf ich kauf ma morgen eine neue CPU dann geh ich mim FSB rauf.
Nur ich seh keinen Sinn drinn weiter rauf zu gehn wenn die CPU ab 2315 nimma mitmacht ! FSB Power schön und gut aber ohne die Mhz..zahlt sichs ned aus !

stimmt für die rev 1.2 sicher nicht!
Memtest86 zeigt nur ~ 1000MB/s. RAMBandbreite an, wenn ich DIMM1+2 belege.
Aber ~ 1800MB/s. mit DIMM1+3.
Den Review würd ich nicht sehr ernst nehmen.

vielleicht ist das bei jedem anders!

@ viper:
wie soll ich bei einer MSI GF4 TI 4200 64MB VIVO die Spannung verändern??? ich habe noch keine Option gefunden!

ja sie werden bei jedn board den bauplan durcheinanderwürfeln
das erklärt auch warum einige boards super sind und andre net gscheid gehn
