Well, it seems my problems weren't caused by the powersupply at all...

The reason was a broken backlight on my Dell ultrasharp LCD panel... :-(

Anyway, good to know that it wasn't the board or anyting.

Once again, thanks for the FAQ.

Hi all, first post :) Great board & site!
My config.
a8n deluxe
FX55
Vapochill XE II
2x6800u.
2gig OCZ
2x ULTRA320 seagate
1x Ehiem waterpump ( cooling HDs, 6800s, chipset)
1xRadiator with 5x120 Fans
1x evacution 120Fan
1xInnovatek fan o matic
1x OCZ 600W PSU ( 12v1&2=38A)

got the same problem as most of you, tested each part all worked fine. when i boot up the full system, the vapochill kicks in...once reached -5c boots the MoBo. i see it checking the CD/DVD, the floppy, fans go on, power led, ide led(ide for approx 40sec), everything, but then blank...no light through the tunnel, no sweet sound from the HDs turning...no screen, nothing..just drulling and a messed up keyboard.

to be clear before i do this, you would recommend to unplug most 12v things,leave 2x512 of ram on A1B1, clear the cmos, and what else... just want to be sure of this before i get the sledge hammer...

Thanks.

Yes, start with minimal config, then update BIOS, then apply new settings with all devices plugged in and keep your thumbs crossed. Nice setup btw, how's that Vapochill doing?

Sultan,

Forgot to add that in our labs the first OCZ 600-watt PowerStream blew up after 15-mins of testing and even took the main socket fuse, 16A with it, 2nd one did not run a configuration with two 6800Us, so this could be your problem also.

>> Re: Asus A8N-SLI FAQ
First off I want to tell you a really big thank you for this FAQ!
Now down to the good stuff, I got my board 1/3/05. I always build systems outside the case to make sure I get rid of all the bugs before mounting. The first thing that I do is to discharge the bios before doing anything else with a new motherboard. My original setup that I used to get the board to post was: 1- 512 stick pc2100 ecc reg Micron memory, PCI Savage video card, CD rom, floppy drive & WD Raptor on Nvidia controller and a EPS-12V 500w power supply. It booted the first time! Installed XP then loaded all drivers from the installation disk. Installed SP2 . I then changed the memory 2 sticks 512k Patriot Extreme Cas2 PC2700. then removed the video card and installed 1 Leadtek PX6800 TDH and rebooted. Installed the drivers. Installed the second PX6800 and set the board to SLI. No new bios was available at that time. I have had only 1 driver problem and that was Nvidia related and the new one solved the problem. Success story!
The one thing that I found in doing this was that when making a change in the memory you should remove the battery from the board and discharge the bios before installing different or more memory. This may not be the answer to memory problems that many seem to have but it seems that this board is a little twitchy when installing memory

Thanks Again,
Russ.

i have a Ultra X-Connect 500watt psu, is this good enough for the A8N-SLI and i understand it requires a 24pin connecter, i'll just buy a converter, what do you think, wise idea?

I have just bought this same motherbaord and I'm not having the best time with it. I put everything together and everything was running fine for a day or so. Last night when i tried to get on my computer my monitor was in standby and i couldn't get it to come back on. I tried restarting, it restarted just fine but still no video. I went to Best Buy and bought a new video card just to see what was going on, still same thing. Put the video card in hooked up the monitor cable and soon as it boots my monitor goes into standby. I tried clearning cmos, thinking it was bad video drivers, but still nothing.

I'm not getting any voice errors with a speaker hooked up to the board. The computer turns on just fine and runs but no video.

I let it sit till this morning and took it into work with me to see if i could get it working again. When i tried it at work i got the Bios post sreen and the the SATA setup prompt. Just after that it said, CMOS checksum error: Loading Defaults. Which i assume was from reseting CMOS, and the computer shut down. Now everytime i boot again, i get the same thing. no video, monitor goes into standby, but computer runs.

I've tried taking out the CPU and RAM and boot to see if i could get an error or beep. I put both back in by themself and still nothing.

What might i do to fix the problems I'm having. I'm not too good with power supplies but it seems i might be under powering the motherboard after reading this board.

The power supply reads as is :
input: 47hz-67hz- 100-125v-,5v/200-240-2.5A
DC output

+5VDC +12vdc +12vcd -5vcd +3.3vcd VSB
40a 1a 14a 1a 28a 2/5A


This power supply was bought for the last AMD system i built. Maybe someone out there can tell me whats going on or give me something new to try.


Thanks

Is 39 degrees celsius (102.2 degrees farenheit) a good temperature for an idle fx-55 chip with stock cooling?
Also is 41.0 celsius a good full load temp for a 6800 gt?
My memory is running at 2-3-3-5 and its rated at 2-2-2-5 and i have it set to 2.75 volts which is also supported by memory but i left all other stuff set to auto like ras to cas and other latency values... what could be causing this and if i set it to 2-2-2-5 will it make the board unstable?
Thank you for your responses :)

Sander,

15mins? the second one not even starting it up??? Now that is a serious lack for OCZ...searched a while and only found this one. even the Thermaltake 680W doens't have as much Amps...
Otherwise yes my machine is a beautiful machine...as much as a decorated christmas tree in middle of july. it weighs 32kilos, gotta move it with 4 horses attached the caseis a UFO 48x48x48cm dimension.... back to the subject.. 600w ocz not reliable... what to take then? got anything for me ? thought of the double PSU, but heck.... i would need to get a new horse to move it, and ask and architect to make me a new top for my case :) Maybe a server PSU adatped for my config would be the best... but i am not ready to do that, its not my field. basically this is what would be needed.
- 2x 6800U adapter (4 pin) (same rail or different?)
- 1x12v EZplug
- 2x12v for the DvDs
- 1x12v pump (or extra)
- 1x12V lights(very lowAmps)
- 1x12V fancontroler
- 1x12v extra just in case you wanna put a plasma ball to make a new movie with will smith.
- and of course the 12v 4 pin for the mobo
nerally forgot the floppy...
minimum 38Amps on 2 12v rails.
If someone mods a very good psu that way, i bet you many many will buy it. So many people looking for a PSU in that config. Anyone wanna try to make? Sander, commmon.. ill be you first customer :)

the vapo, honestly is a dream, once well installed, you can go nuts with the CPUs...a must have for serious performance gain. espacially now it doesn;t pump juice from your PSU any more...apparently it should be pumping it before.: wall>psu>"Relay chillcontrol">mobo/compressor is the path. but only shoots the mobo once its passed -5c meaning full load past.

Anyhow.. gotta go do a couple of things, will try to unhook all this and buy some red mercury if it doens't work... any one got a small nuke plant i could borrow?

My temps are looking high to me with no OC. What do you guys think?
Idle:
CPU: 45C
System: 38C
GPU: 68C

With my case sides off it cools dramatically by 10C on CPU and GPU.

David et al,

My temperatures under full load with an FX55 fitted with a XP120 and 120-mm, 1200-prm fan are 45C CPU, 38C case and about 80C for the 6800 Ultras.

Hi Sander,

I ordered the Antec 550w ep12 PSU as suggested for fx55 and dual 6800s, but i'm having second thoughts, cuase of:

thermaltake 560w gives me 11.4-11.5v on the 12v rail
thermaltake 560w and thermaltake butterfly 480w (2 psus, 6800s on butterfly 480w), still gives me the same voltages

any thought? bad mb readouts?

regards
anthony

Anthony,

Well, I have not got any thermaltake PSUs here, but they are notorious for not delivering the Amps they rate for the PSUs, so I would be careful. Antec on the other hand is often capable ot putting out more Amps than specified so you've got quite a safety margin.

Hey,

Anyone using Mushkin PC3200 222 L2 V2 memory with the A8N-SLI? I'm having problems with motherboard stability, and I'm not OC'ing (yet). I bought this memory for it's quality and low latency of CAS 2-2-2-5 knowing full well that it is not yet listed on ASUS-approved list. I've read thru this faq and quite a few other forums and this has helped. (Nice faq by the way!) Initially I left the BIOS DRAM settings at Auto and began installing WinXP Pro. This produced intermittant CDROM read errors, and sometimes a BSOD. You can imagine my confusion as it took quite a while to narrow the problem down to DRAM settings. So when I finally relaxed the settings to 3-3-3-7 everything installed ok and appeared to be stable, but this is not acceptable. Next, I booted and ran a Memtest86+ CD at the 2-2-2-5 settings to see what's up, and the errors that showed up were almost exclusively memory block move errors. Maybe a DMA/controller issue? Or maybe this most excellent RAM is just not compatible with this mobo? Does anyone have any insight on how to get this RAM to work at the stock 2-2-2-5 settings? I haven't given up yet! My rig:
A8N-SLI Dlx Rev 1.02 BIOS 1003 Final (I flashed the stock 1002)
Athlon64 3200+ w/Thermaltake PIPE101 sink & UFO fan
Mushkin 1GB DualPack PC3200 222 L2 V2 (2x512MB)
PCPower & Cooling Turbo-Cool 510 SLI power
BFG Tech GeForce 6600GT-OC PCIe
2x WD760GD Raptor RAID1 on NVRAID
Plextor PX708A DVD
Antec Super LanBoy

BTW, I contacted ASUS and got what is probably the most lame and poorly constructed response I have ever seen: "Sir, I thinks it's your memory issue , Actually , Memory ofter lead to blue secreen when you installl the OS . So you could properly adjust your memory parameter for get stable surroundings , if not , you could change other memory to try. .Best regards !"

I think ASUS is in deep trouble.

Cheers,
George

update,

ok.. no problem with my OCZ600W.. i think.
i can stay in the bios for a while it wont shut down. BUT once the HD shoots.... i just see the boot up screen for 3secs, then a very quick blue screen (it is so fast you cant see what is written) then shuts down...
Any ideas.

BTW !! OCZ Ram was the reason. i changed them to twinmos pros 2.2.2.5 and no more problem....except for the shut down during the boot up screen.
guess i am getting somewhere lol.

thanks for the reply.

I check both PSUs on an ''old'' p4c800 dlx and a 3.2ghz p4 and it does indeed keep to 11.95v

hope the antec is ok for my system

thanks again

Hi there,

Just a quickie (I hope)

My board was working fine until I stuck in an extra stick of RAM.

I ran memtest86 overnight and no errors if I use both the black slots.

If, however I use the blue slots, I get errors. Ive tried booting with one chip in one socket and moving it between the 4 slots, and it will boot if either stick is in A2,B2 or B1. If I put either into A1, I get the memory beep. Therefore I believe that my A1 socket is screwed.

Does anyone have any other ideas ? - Is there something that I can do to fix it ? - is there perhaps a definitive test I can do ?

Also I noticed that on Memtest86, it says "chipset not recognised" - does anyone know of a good memory tester that is reliable and accurate on this board.

Thanks

Welp... I just ordered a new power supply for my mobo but here is my problem:

1x430watt crap PS
1xAsus A8N-SLI Deluxe 1.002 BIOS
1xAMD Athlon 64 3000+
1x 6600 GT
2x Corsair 256MB DDR400 XMS3200 Dual-Channel Memory
1x Western Digital SATA Raptor WD360GD
1x WD 80gig IDE (PATA) HD with 8MB cache

Things seemed to be going well.. and THEN. If I try to read/write a lot from the PATA IDE harddrive, it either hangs the system or I get the error "Delayed Write Failed" and basically I cant use the drive anymore after that. A reboot doesnt fix it. I have to power down the system, wait 5-10 seconds, and then power it back up. Magically the drive is back after that. Arg!

BTW... I am 100% confident the drive is fine. I used it in my other system less than a day ago and even put it back in to verify.

Any ideas on what could cause this?
