K7N2 Delta-L Poor memory results with dual channel, please help !

CPU Barton 2500+

Memory 2x256meg

memory setting 7-3-3-2.5 manual (spd is using timing of 8-3-3-3)

Program Used Sandra Sisoft Pro 2003.7.9.73



1-Should I use synch or asynchronous setting for the memory FSB, 166mhz or
200mhz ?

2-The result I got are 2500mb/s and 2400mb/s, very poor compare to Intel =
around 5000mb, even my other computer with P4 2.8fsb533 rambus 1066 is
having arounf 3300...

BUT the problem is that memory results are the same using SINGLE or DUAL
CHANNEL configuration...

I show DUAL CHANNEL when it boot but the results are still the same...

THROW ME a bone here ?? The Nforce 2 chipset SUCK or what ? On the MB box
they wtote theorical memory bandwith up to 6.1... Sandra told me 2600 mb/s
and it cannot identify the memory banks neither...

PLEASE HELP. is it normal that the results suck so much and to see no
difference between single and dual channel configuration, it is only a
marketing ?

thanks !

 

One of the reviews that I read on Tom's Hardware of nForce2 boards said that
CL2 DDR was a must for dual channel operation. Just what they said.

Did you happen to look at the reference chipsets in Sandra?
The nForce2 w/ PC2700 dual channel gets 2566/2456. So that's around
what your results are. Almost all the tests I've seen show negligible
differences between dual and single channel on nForce2 boards.
The best Intel based boards with the best RAM should get about double
the nForce2 memory bandwidth.

 

well thanks... precisely what I thought, dual channel using nforce2 and
AMD is a bad joke... at least this is not my computer...

and who design the retail heatsink ? it's loud and annoying, poor
design... Silent boost from thermaltake will replace it soon...

 

2-4% in those types of memory tests with non-integrated graphics, is about
right. Your improvment is 4%. Check out this article:

Its not really that bad its just not as good as the top Intel based
chipsets. And the dual channel memory can be significant in using
onboard GPUs.

 

but should I used synch or asynch FSB for the memory ? 333 or 400 mhz ?

I readed that if I run in synch mode it should be better but bring
instability ?

thanks

 

Don't be so quick to dog that mobo. Just because a P4 system gets twice the
mem bandwidth doesn't mean it is faster. The P4's need all that bandwidth
just to remain competitve with the Athlons. Clock for clock a P4 gets it ass
handed to it by AMD.

 

What are you trying to say? Benchmarks don't mean EVERYTHING? What a
concept.
