A7N8X-X setup

[John]

I put a second stick of 256M 3200 in so I could use the parrallel memory and
my BIOS showed a checksum error and went to defaults.... what a mess. Took
me an hour to get it to boot again. Now I am confused as to what I had
before and what I should have.

A7N8X-X
Althon 1800+
2 sticks of 256 3200 memory
Radeon 7500
zip 100
cd r/w
dvd

BIOS shows 100 meg CPU freq
200 meg memory freq
7X15 CPU multiplier
1.65 Vcore

How should this thing be set for my hardware. Appreciate any help..

John, your multiplier should be 11.5, and your memory should be 133.
Everything else should be set to either Auto or Aggressive. (that is not
overclocked)

Also make sure the ram sticks are not installed side by side in the slots
use 0-2 or 1-3 or 0-3 etc etc

Maybe it set to 100= 200mghz fsb
try the 133 mghz set for athlon xp
and the multiplier to 11.5 / depend on what you got.....

a got an xp 1900 set to default multiplier set at 12
take a look at the jumper to with the book

my board is a nf2 a7n8x-x
and that version dont have dual channel
it the same witn the kt400 version.

BIOS shows 100 meg CPU freq
200 meg memory freq look's find for the mem
7X15 CPU multiplier
1.65 Vcore

vcore should be at 1.5 in the bios

could you try a memory benchmark for me with that program ( aida32 )

http://www.aida32.hu/aida32.php

cause with my setting i ONLY get 1900mg\s of memory bandwidth and a
have a pc2700 ddr module. 512megs kingston

i should get around 2700mg/s as for the pc3200 > 3200mg/s
i would love to know if your board is doing the same thing as mine.

 

[John]

OK I'll try this ... I only have three slots for ram so assume it should go
either slot 0-1 or 1-2... will try both... right now i have it in 0-1 and
it shows all ram...

John N.

 

[John]

OK, it worked at 133MH and 11.5 multiple. Thanks....

John N.

 

[John]

I got it to work at 133MH and 11.5X... so far so good.. will download the
benchmark and see what I can give you...

John N.

 

[John]

OK, I couldn't set the Vcore to 1.5 because it doesn't go lower than 1.65...
I downloaded your benchmark and got 1858MHz for memory read and 720 for
memory write.. Not sure if that is good or bad... I would have thought it
would have been higher..

Ho it's not to get the best score around that, i ask this.
On the manufacturer site they say generaly that a ddr 2700 should go
to around 2700mg/s in memory bandwidth but it does'nt go that high for
me and i see, in your side it the same, so in one way tanks you.
comclusion i need a bigger cpu to get around that factory spec.

works find at 2000 @1666mghz (133x12.5)

If by 'parallel memory' you're referring to dual-channel memory, the
A7N8X-X does NOT have this!

what are you talking about?, this board supports dual channel ddr400

Just as Gordon wrote, yes it does.

Here is a snipette from Asus Website:
The ASUS A7N8X-X Series has come out with another winner to offer incredible
value. The A7N8X-X, using the nForce2 400 chipset, is ready for the newest
Athlon XP processor on 400Mhz FSB. Other industry-leading features include
AGP 8x graphics interface, DDR400 memory, onboard 6-channel audio and a
whole lot more.

Sorry, you're both wrong. The A7N8X-X is single channel only. It uses
the nForce2 400 chipset which is the cheaper single channel version of
the nForce2 Ultra. That's what the -X suffix means.

Thanks for clearing that up for me. I probably caused my problem because I
inserted my two sticks of 256M 3200 in slots 1 and 2 or is it 2 and 3.
anyway I left the first one open and it didn't work.

Thank you for the heads up. I was unaware of this.

X vs DX my heads spinning....whoops

X vs DX my heads spinning....whoops

I don't blame you. A7V8X, A7N8X, -X, -DX, etc. etc... it's easy to
get confused. I had to post to usenet to find out the differences
between the -X and the -DX as the Asus website certainly doesn't make it
clear.

For the record, I bought an A7N8X-X, not needing the extra features of
the -DX, to upgrade an ECS K7S5A and am very pleased with it so far.
It's nice and stable, very quick, the onboard sound and LAN work well,
the additional USB ports are handy, and I have overclocked an XP2400+ to
2700+ without problems.

The only thing I had trouble with was the IDE controller. The hard disk
"felt" rather slow in Win2k even though benchmarks showed it was working
okay and Device Mangler showed it was operating in Ultra DMA Mode. I
tried setting the IDE channel to PIO Only, rebooted, and then set it
back to Ultra DMA and speed really improved after that.

Should the IDE controllers be showing as "Standard Dual PCI IDE
Controller"? Installing the NForce drivers did not change this and I
have been reluctant to experiment with different Nforce drivers, hearing
that some of them had problems with the IDE drivers.
