update:
third time installation now proceeded past the troublesome point ... i will test further wether the DVD drive fixed the problem or my BIOS underclocking/safe value settings and report back. I do NOT like problems that just go away and i don't know why, so i'm going to find out.

if anyone already knows the solution, please clue me in to save me some time, thanks.

BoxOrox,

As documented in various other posts that PSU you're using is not recommended for this motherboard or SLI.

Lee,

You won't regret that purchase, that's a great PSU and will handle SLI and any other high-end configuration with ease. There's a reason I listed it as the recommended PSU for SLI.

How i solved the Windows XP Pro installation problem "can not copy file from disk" (usually included 'iexplore' and other files). Note that this procedure helped me install on a standard EIDE drive, not SATA!

I solved the problem by changing the following BIOS setting:

Go to the "Advanced" page and enter "Onboard Devices Configuration" and there choose the first option "IDE Function Setup".

--- Disable this setting: "IDE DMA Transfer Access" ---

I suppose that Windows XP has issues using the DMA transfer on Nforce4 boards or this specific board. But i also wonder if that could mean that i have a defective board? I remember that if windows is newer than the chipset of the board it can sometimes troublesome to install and run untill the chipset drivers are installed. I will do some further tests but i don't feel good about having to disable DMA Transfers, it just doesn't feel right. :(

Btw, in the meantime i also have replaced the IDE cable as well as just disabling the UDMA transfers for the CD-ROM instead of for all IDE controllers, but neither helped.

Wow lots of info here,
Here's my problem, I'm getting random horizontal lines whenever the system goes into SLI mode, at first I though it was an overlay problem because whenever I took a game into windowed mode it would go away, but now I'm pretty sure that when that happens the system goes back to single GPU rendering (I lose the GPU load balance display)
Anyway It seems to occur whenever there is a 2D overlay on top of a 3D environment (game menus and HUD are both good examples) also it tends to become MUCH worse as I increase the resolution.

Other than this I'm extremely satisfied with the system, all tests turn out well.
Each vid card runs flawless on it's own

So here's what I've done so far,
Mobo bios updated to 1003 (can't find the beta 1004's you mentioned)
Bios setup as per this thread.
Video cards are the same firmware (at least the sticker on them says thay are)
Tested memory with memtest86 no errors
Tried every nvidia driver I can find.

Here's what I'm working with:
Asus A8N-SLI Deluxe
AMD Athlon64 FX-53
Asus EN6800 Graphics x2
Corsair VR??? 2x512
WD 120GB SATA
Ultra X-Connect 500w PSU

Spoke with Asus and they seem to think the problem is with my Motherboard but it seems alot of people are having the same trouble with these particular cards so I thought maybe someone could help me out.

P.S. I understand that when you put the board into SLI mode the PCIx slots step down to x8 each making a total of x16 between the two,,, now the display properties only see a single video card (although 2 show up in device manager) should the Nvidia 6800 display properties be showing x8 or x16??? mine shows x8...

Thanks,
Brian

Hi everybody,

I get a quite strange effect concerning the A8N-SLI, but first my specs:

ASUS A8N-SLI Deluxe, Rev. 1.02, bios not updated yet
AMD Athlon64 3200+
2x 512MB MDT PC400 CL2.5 Double Sided (A1 and B1)
Tagan TG 480-U22 - 480 Watt
inno3D GeForce 6800GT PCIe (blue PCIe-Slot)
250GB Seagate ST3250823AS SATA 8MB
DVRA Plextor PX-716A
DVDA Plextor PX-116A/T3
Floppy

The behaviour of my MB is quite similar to the "no-monitor signal effect" already mentioned:
My PC wont't boot, no beeps or vocal post message occur (even when I remove both memory modules and/or the graphics card). There's only a vocal post message, when the cpu is removed.
This effect has already been mentioned and seems to be a bios problem.

I tried to boot with only one memory stick in Slot B1 (after clearing CMOS according the instructions in the manual), but the system nerver complets POST. Tried different graphics cards, no changes (I even tried an old PCI graphic card, no difference).
Tried to update the bios by EZ flash utility, but the system doesn't recognize my floppy drive. Changing the floppy and/or the floppy cable still doesn't work.

Anybody any further ideas, cos I don't know what more I could try.. Thanks ;)

@Wolfgang: have you checked the "polarity" (alignment?) of the floppy cable? Quite often it is possible to falsely connect the cable to the floppy without using any force or any indication that the cable is plugged in the wrong way. Then the Bios can't find the floppy and the PC won't boot. Maybe that helps.

I would also unplug all unused drives for testing, does the PC complete POST with only the HD attached?

Hi, I am new here. I have searched everywhere and can't seem to find a solution.

I am trying to get win xp pro installed on two 74GB raptors. The drives are in a raid 0 on the nvraid. They are on ports 1 and 2. I have the silicon image raid disabled and the nvraid enabled, with only sata 1 and 2 enabled under nvraid. I was able to get the two drived raided as a raid 0 under the nvraid rom bios. I set it to bootable, and it diplays them as a raid 0 healthy. The problem is once I put in the xp cd to boot from, I hit F6 and use a froppy with the nvraid drives from the ASUS cd. I choose the nvidia raid option, not the storage option. Once xp is done loading driver support it sees not one raided drive but both 74 gb raptors as two seprate drives. I can choose either one to format and insatll to. How do I get xp to see them as a raid like normal? I have tried installing to one of the raptors but it says disk read error after the first reboot, after xp is done copying the setup files to the drve. I assume that is because it is a raid and not a individual drive, but xp is seeing them as individual even though the raid bios sees them as raided.

Also, I tried insatlling xp to an IDE drive then installed the nvidia drivers. I was ablle to format and raid both drives as a raid 0 in windows. windows saw them as one drive then. After that I tried to do another insatll, but it would see them as two drives durring the setup.

I have a

A8n SLI Deluxe
FX-55
600 WAT PSU
2 GBs Corsair Twinx
2 MSI 6800 Ultras
2 74 raps

nec ide 16x dvd-rw
lite-on 16 dvd rom
a sony floppy

win xp pro

Thanks,

Mike: as far as i understand that is correct, meaning 6800 appears twice in device manager and once under display properties. Each card gets PCIe 8x transfer speed, so 8x for the primary video card is correct as well (the second doesn't show up on display properties because you can't configure it individually, since they have to be synchronized in every manner to run in SLI mode).

Update on first week with system.

I hadn't any issues until last night. I installed an old favorite game of mine, Combat Flight Sim 3. I loaded it and I got a BSOD with the NV4 dll infinite loop error. So being that I can't accept errors and MUST solve the problem, I proceeded to do a few test.

-disable SLI - didn't work
-lowered graphic settings to minimum in game cfg - didn't work
-uninstalled forceware 71.xx and installed latest NVidia offering (66.93??) - windows wouldn't start (another BSOD)
-installed latest forceware 75.90 from guru3d - worked perfectly in SLI and full graphic settings - as did everything else.

Just thought I post this little event for anyone that may have some similar BSOD's. The new 75.90 drivers seem to work good. Don't know exactly what they've done in this latest release, but oh well it works!

A8n-sli deluxe
AMD 64 3500+
1gb corsair xms pro 3200LL
two maxtor 80gb SATA in raid 0
two XFX 6600gt's in SLI
plextor 716SA SATA DVD RW
Ultra 31650 500w PSU

Yesterday I tried a new PCI Express card, a MSI 6600 GT, and it worked at the first try, so it is true that there are many defective graphic cards out there...

Updated to 1004, no more problems by now. If I have time I'll install the software this afternoon... (Windows, Ubuntu (Live-CD worked fine yesterday!), etc.)

@ sdfsdfsdf sdfsdfsdfds:

Thanks for your quick reply
I think, the drive is connected correctly (I tried two different floppy drives and two differend cables), because one of the floppy cables I use allows a connection only in one way, so it shouldn't be possible to connect that cable in a wrong way.
Btw: both floppy drives show the same behaviour: the green LED doesn't flash at any time.

It was not possible for me to use the CrashFree Bios 2 Utility:
- The Floppy drive hasn't been recognized
- When I burn the latest bios on a cd, no update is performed (is it possible to update bios this way?)
- The support CD should contain the same bios version as on the eeprom, so updating the bios shouldn't make sense this way, does it?

Although you can run SLI with settings as per the only card displayed or monitor 1 in Display Property Settings it's better to adjust each card individually and synchronize if overclocking before using SLI..

Yes there will be two cards in Device Manager.
Yes you can adjust them individually.

My post is back on page 30 or so now and still no replies - I'll paraphrase:

Original post - http://www.hardwareanalysis.com/content/topic/38623/?o=572

Installed one card. All fine. Couldnt install 71.81 - BSOD. Changed boot.ini. All fine.
Cannot activate 2nd card as SLI mode - message is:

You must remove any graphics cards that are not compatible with NVIDIA Scalable Link Interface (SLI) technology before you can enable SLI.


The cards have identical BIOS from same manufacturer - what am i supposed to do now?

Thanks in advance...

To Quote your post:


Looking very carefully at the two cards, they have the same lettering in the top corner - SPPX43 REV216A03. Only minor difference is one has a black (timing crystal I think) with MAGIC SHLP 1207-1R0 and the other has a crystal (in exactly the same location) that is shiny silver, with no readable writing. Guess they can change items like that out without changing the board? Just a component supply issue?


I may be wrong, but by your description I would not trust that those cards are truly IDENTICAL. As far as what I've seen written on this subject, the only safe bet is to purchase two IDENTICAL cards at the same time to ensure that bios, revision and etc are all the same. This is probably what is wrong with your SLI setup. Also, try the new 75.90 forceware from guru3d.com. I would try that but if it still won't work, I'd try 2 IDENTICAL CARDS.

update on my installation problem:

I finally stopped trying to figure out what is wrong and went ahead installing windows XP with DMA transfers disabled. As soon as the file copy process was over i re-enabled the DMA transfer before the first time windows started up. Everything worked fine, i installed Nforce and Gfx drivers (66.93) and SLI was detected right away. No problems so far, i ran all 3D Marks, Doom3 demo, Spellforce (to my surprise it supports SLI and scales very good!) and World of Warcraft (which didn't utilize the second GPU, a shame ... i hope it will be supported in future).

However, Doom3 demo load balancing showed no effect of the second GPU and i had the same slowdowns (Vsync enabled) as with a single GPU ... strange. Will try with newer drivers and retail Doom 3.

So far my first impression of SLI ranges from disappointment to sheer amazement! More of the latter ... :)

Sander,

Thanks for the help before - had no power. Turned out to be the PSU. Currently using a friend's while awaiting the arrival of my 'Beautiful Beast'. Pity that I did not learn about you earlier. Anyway, things are running well now.

In your initial setup you use the same memory I have: OCZ EL Platinum PC3200 2-2-2-5, 512Mb.

Have you tried using 4 of these in a system?

I have four, but only two will function at any time. The system functions perfectly, but only the first Gig is recognized by the BIOS. Swicthing them round has no effect.

In addition - I note that many posters have had trouble with this memory. They are marvelous things, from my prior experience, and well worth some effort in getting to work.

This board is obviously also very particular about its RAM. Only a particular matched pair will function in a pair of slots; A1-B1 or A2-B2. I can't explain why this should be, as 'matched pairs' only relate to selection of specific parts in order to optimize their combined function, and basic function should not be impaired by mixing pairs. However, this is undeniably the situation on my particular board.
