Question about ASUS A7V8X Motherboard

6 Answers

Asus A7N8X-X (third memory slot)

The above motherboard has 3 memory slots and each can hold 1GB. There are currently 2 identical 1 GB sticks installed and working properly. When the third stick is installed, however, the new memory registers and tests normally in the post; then, "Windows will not start." This is puzzling because each stick is identical and works normally when installed in either of the first two slots (both independently and together). Any ideas? Here's my system specs:

    I commend you on the prompt response and apologize for any lack of clarity on my part in
    describing the problem. You are correct that any of the three sticks
    work in any combination in the first two slots but none works in the third. After
    the post (when Windows fails to start), I have seen a blue screen with codes
    that looks something like the following:



    I0x0000007E (0x0000005E, 0x89630C95, 0x87328568, 0x87328264)



    At other times, I was prompted to insert the Windows Vista disk, restart
    computer, and select the "Repair" option. After inserting the the disk, the process did not always progress to the "Repair" screen. At which times, the
    computer would simply post and restart again and again. During times when the screen did appear and enable me to select "Repair," the application just ran indefinitely with no indication
    as to the problem or whether it was being resolved.



    As for other memory, I have the two original 256 MB sticks that I had replaced with the 1GB ones. While I don't know how much this information helps, it
    describes the symptoms as I can best recollect them. Thanks



    Best,

    All of the memory sticks are in good working condition, and the only configurations that I have yet to try are those combining the 256 MB and 1 GB sticks, so I will try those. But as it stands, I suspect a bad memory slot. In which case, can it be corrected with replacing the mobo?

    Having upgraded the memory and GPU, I also would consider
    maximizing those capabilities by replacing the 2100 processor with a 3200 (a reasonably priced one, that is). But I'll be starting a new build any day now and have drawn the line at motherboard replacement. I just thought I'd try to extend te useful life of this computer since it still works well.

  • silvertonedl Jul 21, 2008

    Correction: I meant to ask whether it could be corrected "without" replacing the motherboard?

    Good job reporting what kind of system you have - Thanks.

    OK, you have 3 sticks, ALL the same, whenever 1 or 2 are installed, it reports good & works fine [above report from 2Gb installed]
    when the 3rd stick is installed, whichever one it is, Windows won't start. Did I get that right?? It isn't exactly what I saw in your question.
    Since you probably don't have 3 compatible other sticks [512 or 256M] [I'd like to see the result], My best guess is that there is something wrong with the socket. If my assumptions are not correct, with playing around you can tell what additional test to make. Let us know.

You don't mention what type of sticks (ddr333, etc.) The mobo only supports certain capacities depending what you are using. For example, ddr333 is only supported in up to 2 sockets. Maybe you already knew this, but I thought I'd throw it in. It's in the manual, you can download it from Asus.

Interesting I just ran into the same exact problem. I have the same motherboard and 2 1-gig memory exactly the same. I bought 3rd gig to add and it is the same brand and specs of the first 2 gigs. - all from Crucial - Windows wont start all the way, also mouse looks like a big square block instead of usual arrow.
I don't have an answer but do have the exact same problem...hhhmm windows update issue..??

The guest solution was mine. I would say that if the 3rd SIMM socket is bad, then the mobo 'mostly' works. If the 1Gb memory sticks are new, maybe you can return them, re-use in a new mobo isn't recommended due to speed. New ships can take advantage of faster memory & if the old memory chips do work, they will slow down the main chips.

    I don't think so, it depends on many things. I'd first talk to ASUS.

    Keep with the 2Gb for a while, DON'T replace the chip, plan on a new machine next year or so.

OK, you do have other memory, so to check for a bad slot, your 'legal' [available] numbers are:[expressed in Gb] 1/4, 1/2, 1, 1 1/4, 1 1/2, 2, 1/14, 3.

Other configs are possible, but not with the memory that you say that you have at hand. I suggest that you try 1 or 2 1Gb sticks with the 256Mb sticks. If as we suspect, there is something wrong with the 3rd simm socket, you should see problems whenever you use it.

NOTE: Most boards require the denser SIMM to be in the 'closer' spot.

Sounds like either a bad stick of memory or a bad dimm slot . Have you tried the memory on another motherboard ?

What's your problem?bit ix38 quad gt motherboard with 2 gig of ddr2 ram i want to add a 1 gig stick of more ram that ive bought how do i do this? thanks windows seven


Top view of motherboard, scroll down. (Thought you might also like to read the reviews, and Comments)

http://www.bit-tech.net/hardware/motherboards/2007/12/06/abit_ix38_quadgt/2

Motherboard User Manual,

http://www.theraptorpit.com/forum/index.php?/forum/124-abit-motherboard-tech-support-unofficial/

1) On the motherboard the Blue ram memory slot that is closest to the copper heatsink, is ram memory Slot 1.
Also known as DIMM 1.

Ram memory ALWAYS has to be in this ram memory slot.
The Processor reads ram memory Slot 1 first.

2) The Blue ram memory slots are Slot 1 (DIMM 1), and Slot 3.
(DIMM 3)
The Black ram memory slots are Slot 2 (DIMM 2), and Slot 4.
(DIMM 4)

To run Dual Channel ram memory, means there are two LIKE ram memory modules ('Stick'), and they are installed in the SAME channel.

This would mean to alike ram memory modules, in both Blue ram memory slots, or both Black ram memory slots.

Since the ram memory modules need to be alike, they are generally purchased from the same manufacturer, and are the same kind.

Running ram memory in a dual channel configuration, is supposed to increase ram memory 'speed', up to 30 percent.

This is Baloney!
May look good on paper, but in actual use in the field it's cr@p.
Actual performance increase is more like 1 to 2 percent.
This has been proven by Tom's Hardware, and many, many motherboards, ram memory, Processors, etc.

So you have 2GB of DDR2 Sdram, huh?
Is it just one 'stick' of ram memory, or are you referring to two 1GB sticks?

If the above holds true install them in Slot 1 and Slot 3.

If not, and it is a 2GB stick of ram memory, be sure it is installed in Slot 1 (DIMM 1)
Install the 1GB stick in Slot 2.

It isn't the same as the 2GB stick.
It is 1GB.
Does NOT go in a dual channel configuration.

(Catching all this? There is NO dual channel ram memory!

It is ram memory that is -> ALIKE, and used in a -> dual channel configuration.
Used in two separate ram memory slots, that support the dual channel configuration.

Sold with the advertising scheme of 'Dual Channel', but really just means the two ram memory modules, (Or four), are -> alike.

1) Same Voltage used
2) Same Ram Timings
3) Same Chip Configuration
4) Same size in amount
5) Same frequency rate ('Speed')

With ram memory in a dual channel configuration, the ram memory modules team up on the task.)

Info from the manual:

Memory configurations

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.

• Install only identical (the same type and size) DDR DIMM pairs

using the recommended configurations.

• Make sure that the memory frequency matches the CPU FSB

(Front Side Bus). Refer to the Memory frequency/CPU FSB

synchronization table on the next page.

• This motherboard does not support double-sided 16-bit DDR DIMMs.

• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.

hi

your motherboard supports following RAM only

Note: PC2100/PC1600 up to 3 DIMMs; PC3200/PC2700 up to 2 DIMMs; 1GB PC3200/2700 with 32 DDR chips up to 1 DIMM only)

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset


According to the manufacturer's web-site:

http://usa.asus.com/product.aspx?P_ID=0pKBwEIE8tqMT4j7


this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.

I have problem about ram


If the manual says this motherboard support up to 1 GB RAM, you cannot put 2 GB. You can put 2x 512 GB RAM or 1GB RAM
Also try to upgrade your bios, maybe a better bios version supports more than 1 GB RAM.

Memory upgrade issue


Most ram has to go in pairs. Buy another stick of the 1GB, and it will run fine.

Upgrade from 512MB to 1GB


The specs on the memory are correct, so you purchased the correct type of memory for this motherboard. If your getting no video when you power on with the 1gb stick, I would be willing to bet the 1gb stick is bad. Can you return it and try another stick?

Motherboard Missing instruction manual for dual mode memory


Your instruction manual for the mother board should have this, however, with dual-channel motherboards, you will want to fill the same colored slots together if you have dual-channel capable memory, otherwise you'll want to fill in the off-colored slots first.  ASUS has it's manuals online, so if you've lost yours you should be able to download a pdf of it from their website.
