I just purchased an ASUS A7N8X, AMD Athlon XP 2400+, and one 512MB Stick of PC2700 DDR Memory in DIMM1. After installing it into my computer (MCI nVidia GeForce4 Ti-4600, Soundblaster Live! Value, Antec TruePower 430W, ATX Case, IBM 7200RPM 20GB (Windows XP Professional Installed) Standard Floppy, NEC DVDROM, 8x CDRW) I could not start Windows XP. The computer would diplay an error really quick that I couldn't see just before the Windows loading screen and reboot. So I reinstalled Windows, but am still having the same problem. BTW, I installed it with the NTSB partition. Another problem that may or may not be related is that I when I hooked the two cd/dvd drives on the secondary ide cable it doesn't recognize both of them, only one and even then that drive will not work properly. I can only hook one up for it to work properly. Last when reading the manual for the board it doesn't say anything about installing just one stick of memory. Does this board need to have two or more sticks to run properly?

I am not very familiar with building computers or BOIS as this is the first time I have ever installed a motherboard/processor setup.

Any help would greatly be appreciated

There could be a number of problems. First, about your cd-rom drives not working, make sure you check the jumpers on the back. You most likely have them both on master/slave. You don't have to have 2 sticks, its just that your board has whats called the dual channel ddr400. Means the first 2 dimms running 400 ram can double the badnwitch up to 2.1 gb/s. I know I've had that quick error screen flash quick but I couldn't catch it. I can't remember what it was. Also, about those cd rom drives and your hard drive...check what ide controller their in because the A7N8X has raid support, and if you have the on the wrong controller you'll have problems, and also check the bios and make sure you have RAID turned off. Try those for now and let me know if anything happens, if not, I'll post some more things you can check/try out.

Happy Gaming

I reset the board and put in an ata133 harddrive and another stick of ram and the computer is fine now with just one problem. Sometimes while installing something the computer will just restart without warning, and always while playing games the computer will either restart or it will exit out and go back into windows. Any suggestions?

well I ahd exact the same problem, I solved it by only ataching 1 cddrive and 1 harddrive, activated in the bios do not halt on errors, installed windows, and then did a live bios update with the tools on the cd, after that everything worked fine.

I have almost the exact same hardware but I run on Win2k.
It sounds like your having a resoirce conflict. Check in your Event log and see if it's helpfull. I had 2 issues (not like yours) in there that I had to resolve after intalling this board.

I have this motherboard and have had this problem as well. What I did that fixed it (though I'm a little perplexed about this) is sync up the RAM in the BIOS with the FSB.

It seems that this mobo has a lot of issues with RAM, it's really picky!

I'm kinda upset about this because i could have just bought pc2100 ram since that's the speed it's running at. I can't seem to go over that without overclocking.

We are seeing alot of the same problems as describd here. We are on Windows2000Pro and have the DELUXE board. Here's our problems:

1. System reboots intermittently in game(ageofempires) or while browsing. Occasionally reboots outside of this as well.

2. Some conflict with LAN cards(onboard) conflicts with DVD ROM...the builder disabled both and somehow the 2nd DVD( master is CD-RW) works again.

We are running BIOS 1001. ANY HELP MUCH APPRECIATED. Also anyone with conflicts feel free to post your solutions!

Don't know if this will help you in your case, but in my experience with the board Kingston ram is the best ram and the most compatible.

That could solve most of your problems, cuz yeah this board is very picky when it comes to ram.

Ahhhh! I have the exact same problem!!!
I'm using 2 sticks of 512mb Kingston Valuram pc2700 cl2.5. It works great with one stick, but with two, it crashes back to the desktop all the time. I tried putting them in slots one and two, and two and three, but still no luck :(
also, I was thinking about getting a return on the ram (if it's not too late) and getting ocz pc3200 instead for a little more (so I can overclock to a higher fsb), anyone have any experience with that?

I have an even worse problem but somewhat the same. I can't boot into windows at all, and if I boot from a floppy, I can't even find the drive. I put the drive in a different computer and it boots fine, it just wont boot with the stupid a7n8x "deluxe" board at all.

I have an A7N8X Deluxe motherboard with XP 2700+, 1024 DDR RAM PC 2700, DVD Drive, CDRW Drive, Atlantis Radeon 9500....

I had trouble installing windows XP pro...cuz the computer kept restarting in the middle of the setup. I finally managed to install windows XP several times.

However my computer gives me a blue screen when i try to run most of the application and games...I have tried spiderman the movie and splinter both games the computer restarts unexpectedly in the middle of the game after like 5mins.

Also, I only have one stick of Kingston 512MB pc 2700 ram installed. For some reason when i put in the second module the computer gives the blue screen of death..and says dumping memory into mini dump...

Blue screen of death give me these messages, when it comes up(different message each time):

Stop: 0x000007F
and some other errors...the computer didn't leave me enough time to write them down before restarting it self....

My friend and I call my computer unrealiably fast because of this

Can somebody help me? Does anybody have any suggestions

well Kingston pc2700 and this board don't mix too well I"ve found out. While some can run one stick, or even two dual-channeled just fine, others can't. However, Kingston pc3200 is actually recommended! (according to the asus compatiblity chart)
I'm going to get some Corsair XMS when I get the cash

I wrote to asus. one of the problems they mentioned was memory. They also mentioned that i should have a 400W power supply. However i only have a 350W power supply. Could that be one of the problems.

Is there a customer support phone number to contact Kingston? I looked at their customer support info on the site but couldn't find anything.

Yes, it can be your power supply. I had to up mine to 430w to get that board working with everything else. I don't have the kind of memory though.

I have only a 350 watt psu and OC system 2700ddr and now that I reformated my hard drive (since it couldn't boot to xp until I formatted it, and it also couldn't boot with my friends 2000 hard drive), my computer works fine. I only had it restart for no reason once, which is once too much for me, but it's not that bad. Also the oc system memory is kindof cheap and I don't think its running in dual ddr mode which is not cool but oh well, that's what I get for buying cheap ddr.

I am having somewhat similar problems than what I've seen here. I have the standard A7N8X with an Athalon XP 2600+ 333fsb, a 512mb chip of Crucial PC2700 DDR ram, and an ASUS V7700 Deluxe vid card (Geforce2 GTS). I can't run any games without it crashing to desktop or blue screens of death. IE also tends to crash on me alot. I've done some looking around and I can't find any incompatability issues with my hardware or driver conflicts so I'm at a loss here. If someone has any ideas I would much appreciate them.

Well I've heard that Crucial doesn't work very well with nforce2 boards (which as you know the n8x is), but then I've heard it works okay for some people on the A7N8X. Bottom line is though is that this mobo is very picky with ram. It's hard to believe it's gotten such rave reviews everywhere even though it has quite a few ram "problems". The only 512 stick I remember being on the compatibility list (of course it's not the only one's that will work, but they are recommended) is the Corsair 512.

I figured out this problem and hopefully it will help others. While researching some things about my video card, I found something that said that older cards such as a geforce 3 classic need to run at 3.3V on the AGP slot. Well since I have a card thats older than a ge3 I decided to check it out. In the manual it says that it too also needs 3.3V. Unfortunately, the motherboard only can give you up to 1.7V in the AGP slot. All this time I thought it was software related and it turned out to be just a simple matter of voltage.

I also found that while new video cards that operate at 1.5V standard are backward compatable to the 3.3V, it does not work the other way around. You would think they would mention something like this in the compatability reports that ASUS put out (yes ASUS said that the A7N8X is compatable with the ASUS V7700 Deluxe vid card, but they neglected to mention the voltage incompatability).

My RAM works great, I checked to make sure it was all good on working with the mobo before I bought. Thanks for your help, and again, I hope this helps others too.

first my system configuration:
Asus A7N8X Deluxe
AMD AthlonXP 2700+
2x Kingston PC2700 512MB
Asus V7700 Deluxe

i also have the problem that my system suddenly reboots during playing games, but i can't believe that the problem is my graphics card, because when i removed one memmory-stick and tried playing games with only 512MB ram everything worked fine ... Why should the graphics card be incompatible to the motherboard although it works fine in my system with only one memmory stick installed?
I think that i will write a mail to the support-desk of Kingston and also to Asus.


p.s.: i'm from austria and so please don't tell me, that my english is bad, because i already know ... i hope you understand what i mean ... :D

I contacted ASUS about the rebooting problem and blue screen of death.
(My specs are XP2700+, A7N8X Deluxe, Sapphire Atlantis Radeon 9500, DVD drive, CDRW Drive, Allied 350W power supply.)

This what they sent me:

Thank you for your support of our products!
The problem you are reporting is a stability issue and is usually caused
by either the memory, power supply or the CPU running too hot. Please
check with the memory maker to see if the module you are using has been
tested or certified with the chipset on your motherboard. Also, check
that your power supply can supply enough power for your system
configuration and that your CPU's heatsink and fan are properly installed.
First, please check that your CPU is not overheating. You can check this
in the BIOS setup, under Power, then Hardware Monitor. If the CPU is
overheating, please check that your heatsink and fan are properly
installed and that you are using exactly one heat transfer agent between
the CPU and heatsink (ex. Artic Silver). Make sure that the heatsink
compound is applied ONLY to the CPU die and that it is NOT shorting any
surface mount components on top of the CPU or contacting the CPU's pins.
Please check to
verify that your board will properly support the CPU that you have. This
link will list the minimum BIOS and PCB version that you must have to
PROPERLY support your CPU.
If you are having trouble with stability, you can try some testing
software like memtest86 to test the memory you have. When run, this program will create a bootable
floppy. Boot from this disk and let it complete at least 1 pass (7
sub-tests) of the test.
Please ask the memory manufacturer the following questions:
Have you done any certification testing with this memory module and our MB
(motherboard) or any MB using the same chipset at the density you are
trying to use (ex. 3*512MB DIMMS totaling 1.5GB of memory)?
If the answer is no and they just build to a certain
specification/standard, then who's specification/standard do they use and
how do they validate their design? If they just build the memory and do
not validate it how do they know it will perform?
When we design our MB we follow the chipset makers spec. with regards to
We do validate the memory IC maker's reference designs with our MB to make
sure they are up to spec. and if we need to add support for Higher density
Most memory module makers do not follow the IC maker's reference designs
so they can use whom ever IC's on their memory Module. There is nothing
wrong with this, but the problem is if they deviate from the IC makers
reference designs and or even if they use the IC makers reference they
should do some level of validation to insure quality.
We are one of the largest MB makers so one would think that if you were
making a product you would test your product with the most popular
associated products.
Here is a list of memory manufacturers that use our MB's as well as others
to do this type of testing and also will post a guarantee that their
memory will work in our MB's as well as others. Please check the following
websites for compatibility:
Also, here are some setup tips that may help you to set up the system.
Please start by clearing the system c-mos memory following the procedure
in your manual. Make sure the power AND the battery on the motherboard is
removed before shorting the CLR RTC solder points or jumper pins.
You may need to refer to the "Interrupt Request Table" in your manual and
arrange your PCI add-in cards so they do not cause interrupt conflicts.
Some devices just do not get along with each other. You may also remove
your PCI cards to see if this corrects the problem. If it does, add the
cards back one by one to see which card is causing the problem. Anytime
you add, move, or remove a PCI card, please enter BIOS setup and set the
option "Reset Configuration Data" to "Yes" if your BIOS has this option.
This will force the BIOS to reassign resources to your PnP devices.
Next, enter Bios Setup and load setup defaults.
Under Boot, if needed, please set the BOOT order. Then set "Reset
Configuration Data" To "YES". Any other changes you need to make for your
specific system configuration please do so at this time.
Next, exit "Saving Changes" and this should correct the issue.
Also for Windows 9X or ME, they have some issues with CPU speeds greater
than 2.1 GHz (see MS Q312108) or memory above 512 MB total system memory
(see MS Q253912). These O.S. cannot cache the memory properly. If your
CPU is greater than 2.1 GHz, you will need to contact Microsoft Product
Support Services to obtain a patch to correct this issue.
Here are some links for common memory related problems:
Err Msg: "Out of Memory" Error Messages with Large Amounts of RAM
Err Msg: Windows Protection Error in NDIS with a CPU That Is Faster Than
2.1 GHz;en-us;q312108
Err Msg: While Initializing Device NTKERN: Windows Protection...;EN-US;q192397
Err Msg: Insufficient Memory to Initialize Windows;EN-US;q184447
Computer May Reboot Continuously with More Than 1.5 GB of RAM;EN-US;q304943
Computer Speed and Performance May Decrease;EN-US;q259161
Err Msg: Not Enough Extended Memory Available to Run Windows;EN-US;q311367
Troubleshooting Stop 0x24 or NTFS_FILE_SYSTEM Error Messages;EN-US;q228888

Make sure you have a FRESH install of your OS on THIS motherboard and that
the drive was partitioned and formatted on this motherboard. Make sure
that you install the most recent drivers in the following order:
1) Chipset/Motherboard drivers (Example, VIA 4 in 1's for VIA chipsets,
Intel INF and Application Accelerator for Intel chipsets, Etc.) Do this
BEFORE loading any other driver!
2) Latest version of Direct X.
3) Latest Video Card drivers.
4) SCSI/ATA drivers
5) Lan/NIC drivers
6) Modem drivers, then any other drivers
7) Finally, install sound card drivers last.

Also, please check to make sure your power supply can supply enough power
to your system.
If the CPU is below 700 MHz, the power supply we suggest as follows:
300 Watts with +5 Volt @ 25 amps, +12 Volt @ 10 amps, and +3.3 Volt @ 14
If the CPU speed is above 700MHz, the power supply we suggest as follows:
350 Watt with +5V @ 30 amps, +12V @ 12 amps, and +3.3V @ 22 amps.
For Dual Intel MB, Min. P.S. should be:
350 Watt with +5V @ 35 amps, +12V @ 15 amps, and +3.3V @ 22 amps.
For Dual AMD MB, Min. P.S. should be:
400 Watt with +5V @ 38 amps, +12V @ 15 amps, and +3.3V @ 20 amps.
Please note that these are only suggestions and the actual size of the
power supply may be higher than we suggest. Also, depending on the config
of your system, you may need more power than listed above. For example,
running multiple hard drives, CR-Rom drives or other accessories may
increase the power requirements of your system!
Best Regards,
Technical Support Team

So i decided to contact Kingston.

Hope this will help

What's up everybody? Well unfortunately, I also had the same problem as almost everybody on here. My system would reboot while playing BF1942 or UT.

Here's a run down of my system:

(Nothing is OC')
400 watt Antec PS
A7N8X Rev. 2.0 non-deluxe (C1003 bios)
AMD 2400+ (Zalman all copper HSF)
2 x 512mb Kingston Hyper X sticks PC2700 (Slots 2&3)
eVGA GF 4 TI4600 8x 128mb
80Gig Maxtor Ultra 133 8mb Cache

I was running my CPU at 133mhz & my memory by speed, which would be set to 166mhz. I decided to go into the bios & play around with it, & I noticed that when I set the memory to (Auto). Which it sets the memory speed to 133mhz, the same as the CPU. My system would actually run much quicker & perfectly stable as can be. I was also upset because I couldn't take advantage of the memory's speed which actually suppose to run at 166mhz. I guess I can't complaint cause I got it at the same price as the PC2100 & my computer is working flawlessly now. Prior to this system I tried two epox 8RDA+ boards that the mouse would only work every other boot, & a A7V8X that kept freezing on me. Hope everyone here tries this, & hopefully it will work for you too. I know how much stress this can be. Latez!
