normaly u can set the RAM speed in bios
there could be: Set Ram Ratio 1:1
manualy set speed at ....mhz
mostly u have to set settings to manual or something

i can set the RAM Speed with % of CPU FSB on my A7N8X ,,,,,
maybe u should take one or two looks in your Bios

there has to be an option in ya BIOS ...
look for DRAM modulators like 3/6 or 6/6 or 5/6 or 5/4 ... such things

Just set the timing to 1:1 in the BIOS for memory.

It should fix it.

Maybe U got another MB, but on mine there is absolutely no timing settings. A7N8X-VM/400 is an OC no do... Or ??? If any one knows how to do it please :hail: send me a screenshot or something ...

You should have 2 e-mails that I sent to you, saying that it's most likely that the board you have simply does not support PC3200 (DDR400) memory and therefore is running at a slower speed.

ASUS A7N8x-VM/400 is a "NForce 2 400" stepping of the NForce 2 chipset not a "NForce 2 Ultra 400". So it does not support PC3200 or Dual Channel but does officially support 400FSB CPUs.

And the bios on the A7N8x-VM/400 or A7N8x-VM variety does not allow configuring of the memory setting at all. Possibly down to ASUS, or a limitation in the IGP Northbridge.

From the Memory, CPU, Graphics card you have, you should have gone for a better motherboard. If you still can, I would return / exchange it for a better one. I.E Abit NF7 v2.0, ASUS A7N8X.

And from the look of it, the onboard GF4MX would be not use to you if you have a Ti4200. As the Ti4200 is a lot better.

I only decided to register after I sent the e-mails, So that this may help others.

Also I should point out that the ASUS A7N8x-VM, not the ASUS A7N8x-VM/400.
Does happen to support PC3200 and Dual Channel (If an AGP graphics card is installed), but does not officially support 400FSB CPUs. As this will not work for the onboard GF4MX.
This is because this board was release with the earlier stepping of the NForce 2 Chipset.

This board was then replaced with the ASUS A7N8x-VM/400 with the newer steppings of the IGP and MCP, and therefore discontinued the A7N8x-VM.

By the way, I found out all the relivant information by looking at the Manuals available for download on ASUS's Website.

XP3200+, 1Gb TwinX Corsair PC3200, Ti4200 has the makings of a Mid-Range to High system, but that motherboard is just not suitable.

Every one that is selling A7N8X-VM/400 here in Denmark (and ASUS supporter Y.C Zhang) says the bord should support DDR3200 (400MHz) if an AFG card is installed. I wanted this board because it has the SoundStorm TM APU (the best sound I've ever heard). So I have to let Asus and SHG (where I bought the MB) find a solution.. Oh and I do wan't a Mini ATX bord (smaler is better) ...

Unfortunately they must be wrong, if they are right then you should not have any problems. And also the specification page in both the manual and on the website for the A7N8X-VM/400 would say that it supports PC3200. They are probably mixing it up with the previous A7N8X-VM.

As you should already have the manual, you can easily check, as I pointed out in the one of the e-mails. Or you can check the links below:

A7N8X-VM/400
A7N8X-VM/400 Manual

A7N8X-VM
A7N8X-VM Manual

The soundstorm is one of the best onboard sounds available, but you might be a little disapointed to hear that your board IS NOT Soundstorm Certified by Nvidia. Check Here. (Whether that makes a difference).
As your board only includes the MCP2 southbridge, instead of the "Certified" MCP2-T. So technically you only have 6ch audio.
I use a Audigy 2 Platinum myself and disable the SoundStorm in the bios.
Besides there are probably better soundacards out there, I.E. Terratec DMX 6Fire, M-Audio Revoultion 7.1, and the Audigy 2. (Debatable)

And unless you have a small form factor case, I don't see how you can think uATX is better than ATX.

As your board will be lacking the extra USB, Firewire, PCI slots, AMR/CNR riser (if applicable), Third / Forth DIMM slot(s), ATX12V (for extra stability), Optical in/out (Audio), Second Lan adapter, and maybe some other things that I can't think of including the functionality of the NForce 2 Ultra 400 chipset.

I do have a small form factor case : I hate these big monstrums :hmm: , and the sound is sublime, better than my Creative SB Live Platinium, clearer and crisper ... So I'm pleased (Sandra reports : NVIDIA® nForce and that is what I wanted ... And by the way, tested the system against ASUS A7V600 , and it won even though 333MHz to the Ram ??? (Sandra : ram read/write, disk I/O e.t.c), The funny thing is that Sandra reports Onboard VGA enabled and My Leadtek GF4 present at the same time ... Well All I wan't is that it would run 400 MHz on my expensive Corsair ram, else I'm very pleased with this little wonder ... Thanks for Your answer though, very helpfull informations, but no solution ...

really ??? if ya have the /400 ....

CPU Socket A for AMD Athlon XP
Thoroughbred/ Barton Core Support
Chipset NVIDIA nForce2 IGP
NVIDIA nForce2 MCP
Front Side Bus 400/333/266 MHz
Memory -Dual Channel Memory Architecture
-Supports up to 2GB of 2700/PC2100 DDR memory
-2 DIMM sockets

it does NOT have the Nforce 2 ULTRA chipset its just the nforce 2 chipset ... so no PC3200 support

According to Asus (YC Zhang - support) and the Shop (WWW.SHG.DK and others) it does support DDR3200. Thats why I started this tread !!!

so they simply are wrong ...
one of those has to be normal nForce chipset and its yours ...
but you MAY give us all the options you can set within the OC menu where you can set FSB and so on ...
maybe you did oversee something but I am pretty sure you didn't

Refering to the shop you must have bought the board from WWW.SHG.DK they have mixed up the specification with the A7N8X-VM.
For proof, if you click on the A7N8X-VM/400 to get popup of the description / specification for the board. Check up the top, is says:
PRODUCENT: Asus
MODEL: A7N8X-VM

They simply just amended the previous desciption, and did n't correct it properly when the A7N8X-VM was replaced with the newer A7N8X-VM/400.
For anyone how can't speak Danish and want to check, it's under Bundkort in Hardware.

Also they missed 200 after 166, cos the previous did n't support 400FSB so they simply changed the description from the previous board:
FSB: 100/133/166 (200/266/333/400) MHz

They simply are wrong as we've been saying, the board can't do what it has n't been designed to do.
Also the bios does not have any option for overclocking or memory settings, you can't even turn off the onboard VGA. Just check the online manual for screenshots for the bios setting available.

You have 2 options:
1. Put up with the board as it is, running at PC2700. And the onboard VGA most likely taking up some of the system memory for it's own use.

2. Take it back, get a board more suited for your needs. Also get a ATX case, even if you get a Midi/Micro Tower.
Or a slightly more expensive choice is something like the Shuttle SN45G.
Under KABINET for 1.899 pris. As this is a Nforce 2 Ultra 400.
And should be a configurable as a ABIT NF7, and is still quite small, and NO onboard VGA.

Also if you are n't going to believe us, then may be you'll believe NVIDIA.
Here is a link to a Adode Acrobat file, with the specification for the NForce 2. Check Here

It's on Page 2, on the right under "NVIDIA NFORCE2 SPP/IGP SPECIFICATIONS", 4th down.
-Supports DDR400/333/266/200 SDRAMS (SPP; IGP supports DDR333/266/200)

I can't see through these specs. They claim the the IGP chip runs at 333 on the FSB and RAM, and the SSP runs at 400, but my IGP is running at 400 FSB and 333 on the RAM ??? (due to the /400 nametag ???) Is there 2 versions of the IGP ???

you FSB will run at 400 right ... but its not supported ...
ofically there is only 333 and the nForce 2 ultra chipset you do not have is a revised one with full FSB 400 support

what you do now is simply overclocking the chipset within range

but running on FSB 200 depends on ur Bios
i mean that´s my experiences....
i tested on official 1.007, no chance to hit 200
then i tried the "Uber Bios 1.007"....no prob to hit this "magical Mark"

Exactly, ASUS must have added the correct settings for the newer CPU's like the XP3200+ to be detected and to run at 200FSB.
But they cannot do this for the memory, as this is a hardware limitation.

For having a small case, and full support for 400 FSB and Memory, and overclockability.
Still the best solution would be get the Shuttle SN45G, but is quite expensive, and will leave your current case useless. (unless you can return it as well)


Off Topic
Mertsch, you may find that you will get slighty better performance from your Ram if you change your settings to 2-3-2-10-1T or 2-3-2-11-1T.
If you did n't already know. (unless your sigs not up to date)
Due to a fluke in the Nforce 2 chipset, Like Dark Biene and myself, 11 should be the better performer.

yeah I know .... I tried that and also got this improvement
but the system seem to run not 100% stable with this setting ... maybe it was some other thing ... and maybe I will check that again since the PC is working 100% correctly and I can see if this really causes instability or not

What about the AOPEN MK79G-1394 if one prefferes the micro-ATX ??? Can one clock the FSB on this one ... ???
