Mike,

It's a BFG 6600 GT OC 128. However, I figured out what the problem was. After you replied I decided to check inside the case and make sure the card was in slot #1, etc. Well, I decided for the first time to take notice of the EZ selector card which I have thus far ignored. Since I'm not running an SLI setup I, naturally, assumed it was in the proper postion for a single graphics card. Wrong. It was backwards, set for SLI. I guess I'm surprised things were working at all in this configuration, but they were. Anyway, powered down, flipped the EZ connector around and booted up again. Sure enough, when I bring up the display properties it now reads PCI Express x16. Sorry to ask the question before ensuring all the basics were correct. It just never occurred to me that the motherboard would come out of the box setup for SLI instead of just a single graphics card. I wonder if this will affect the performance in anyway now that the card is in the right position?

>> RAID5 and Northbridge Cooling
Dan Dymek: "Has anybody used the A8N-SLI Deluxe's Raid 5 instead of the Raid 0 configuration, and if so have they noticed any sort of performance decrease."

I have 4x160GB Seagate SATA drives, formatted NTFS in WinXP, which comes up as a single bootable 447 GB drive. Writes are slow, reads are fast. ATTO and similar benchmarks all seem to say writes are about 15MB/Sec and reads around 90-100MB/Sec. After a system crash, the array checks itself in the background, which seems to take about 6 hours (pitter pattering in the background). Initial initialization of the array during formatting took about 15 hours from memory. I'm happy with the performance, space, and reliability.

I did exhaustive googling for info on RAID10 vs RAID5 and there's not much out there (apparently other than my post - lol ;). If anyone has benchmarks for RAID10 (NV vs SiI) vs RAID5 I would be very interested. I would like to consider using my drives NCQ capabilities and ditch the IDE bus, if RAID10 was heaps faster (realworld performance).

Tim Acheson: I am with you on noise reduction. FWIW I have a Zalman NJ47 and ZM80D GPU cooler on a XFX6600GT to keep noise down (They *just* fit next to each other). The best thing I ever did was buy a Nexus fan controller which I use to control my front (2) and rear (1) exhaust fans, as well as my CPU fan. I have a Silverstone temp monitor telling me how hot things are. Most of the time I can turn all my fans down to inaudible (6V?) and the system runs just fine.

With all my fans "off" just doing desktop work with winamp playing APE files, my CPU/SYS/GPU temperatures are 47C/38C/55C. With all the fans full bore, I get around 42C/35C/51C (NVIDIA MonitorView). With the bios suggesting 'target' temp for the CPU is 73C, and the GPU temperature alarm defaulting to 127C, I don't see the point of running audible fans. Comments welcomed.

Hi Mike... Thanks for your informative reply. I tried to make a copy of the .inf file and then update the driver of each video card to point to a different file as you suggested, however, i still cannot get games to run in SLI mode. The problem is still the same, it still locks up...Please let me know if you have any other suggestions. Thanks a lot, g

Jase Dee,
On the RAID 10 since you have four itentical drives you would be better off with RAID 10 as it is without parity. It also should be equal or very close in speed to RAID 0 as you are still stripping just using 4 drives so you also have a mirror, hence with 4X160 you will have only 320 - formated Capacity so about 298 worth of space. RAID 10 also provides excellent rebuild performance.
In RAID 5 you have parity but fault tolerence is excellent. Not sure if it is a hardware based solution with XOR on the A8N or software as software is considerably slower. Though since you have four drives you only loss the space on one drive so in the end you have much more space but slower speed than RAID 10. Basically if speed is what you want go 10, if not stick with 5 as an extra 149GBs can be hard to part with. .

Thanks for the note. I am very well versed in the theoretical speeds RAID can provide at various levels, but the proof is in the benchmarks, hence I'm keen to see some real world stats for RAID5 vs RAID10. In doing my research one of the few benchmarks I found was this, which although not related to the A8N this shows RAID5 in many cases beating RAID10 (using a PCI-X Hardware RAID5 XOR RocketRaid 1820A board) for read AND write speed (note this is hardware not software RAID5, but still!).

http://forums.storagereview.net/index.php?showtopic=17953&...&st=25

I know its very different hardware, but it might give you an idea why I am asking an otherwise 'stupid' question. I haven't come across a single website with speed benchmarks for the A8N in RAID10, and I'm very curious what it's capable of considering the removal of the PCI bus bottleneck.

Ok i will tell you the spec before i list my lil problem hopefully it wont happen while im half way through writing this thread.

AMD 64 Skt 939 3500 Wincester
Asus A8N-SLI Deluxe
GF 6800GT PCI-E
1GB Corsair XMS Platinum 3200LL
160GB DiamondMax SATA HDD
Audigy ZS SoundBlaster
Enermax 600w SLI Noisetaker (brought from overclockers cheers lads )

The problem with this setup is that it has a mind of its own and switches off.
There are no error messages in windows in the event log, no blue screens, no noises apart from utter silence when the power goes.
Now i did have a Jeantech 600w 24pin power unit and i got rid of it and after buying the enermax its happend less often. I had the same result with the A8N-SLI as i decided that the motherboard was the problem so i upgraded it to the deluxe only to find that after a longer amount of time it switched off again.
I have noticed that the switching off only occurs whilst the harddrive is in use and that, apart from the graphics is the only thing i havent changed. Normally it switches off whilst im playing CSS or a Game using the Source engine, but it has switched off while i was transfering files across a network or over a usb cable to my external drive.
Memory has been tested and other memory has been used 2 motherboards a 939 3200 winny.
So as I said the only thing i havent really tested is the Sata drive and i really hope your all not going to tell me its that.

No overheating as far as im aware CPU sits below 40c in windows.
Ive not overclocked (yet)
EZ Plug isnt in use as i dont have 2 gfx cards (yet)
All the latest drivers for the board and the bios 1006 (i didnt do it the way Sander said, i used the flash utility)
the card drivers are the PCI-E ones found on nvidia site. 71.84

One more thing. When the power goes off the board still has power like its ready to boot (green LED on board is on) and i am able to hit the power button and it works for a while (30-90 minutes) then switches off again.

There are no error messages in windows in the event log, no blue screens, no noises apart from utter silence when the power goes.
>>>This is normally a clear sign of thermal overload, overvoltage, undervoltage protection from the PSU. You will still get 5V to the board which explains why you see the green mobo light, the 12V rails are shutting down on you though. Set your fan control to full on the PSU even though they claim it's automatic.
>>>Could also be the onboard ATX power on/off circuit that could be defective.
>>>Double check your core shutdown temp for the CPU in the BIOS, should be 72C or so.
>>>There could be other reasons!

1. Another thing on the USB. When I used the USBstick for the last time a few days ago the whole system went bad after a reboot, do you think the problems I had were related to me using the usbstick? Haven't used it yet because I'm a bit scared :) Was it just coincidence?
2. What do you mean by "yes on the pagefile"? Do you mean that I should turn it off, reboot and turn it on again or do you mean you share my doubt of the system booting ok after I turn it off?
3. What do do you think about the bios locking up when I open the sliconfig options?
4. What do you think about this: "What's strange is that I now have options that I didn't have before like the option to turn off the listing of recently opened files in the startmenu list. I missed this option in my previous install but then I had installed Powertoys Tweak UI prior to configurating this. Now I'm a bit put off installing tweak ui, but there are some options in that program I really like: what to do?)" Can tweak ui wreck the system?
5. And finally, on my previous installs I didn't turn NCQ off, do you think this was also the cause for my problems or was it only the 1006 bios version?


And Mike, thanks again for the time you're putting into this forum to help people like me. Asus should be paying you!!

I just thought i would share some maybe usefull information, complain a little and aks a question all in one post ;)

First an update to the DCOM errors from nvidia firewall,
You will need to add the SERVICE user to the local launch and activation permissions with local launch and local activation permissions.

To do this go to Administrative tools-component services, in the treeview expand component services-computers-my computer-DCOM Config, right click on app_filter select properties, on the security tab select customize for launch and activation permissions and hit the edit button to open the launch permissions page, click the add button to open the user and group selection page, click advanced to open the select user or group page, click the find now button then scroll down through the list of users and groups untill you find SERVICE in the list and highlight it then click ok to return to the select users or groups page, click ok again to return to the launch permissions page, now you should see SERVICE in the list of users and groups for app_filter, highlight SERVICE and check local launch and local activation in the permissions for SERVICE, click ok again to return to app_filter properties page and click ok again, now you should be all the way back to the component services page and the SERVICE user has permissions so you wont get any more DCOM errors.

Fix for unknown device after clean install on asus a8n-sli deluxe:

There is a acpi driver that gets installed with AIBooster, if you dont install AIBooster you wont get the acpi driver, (if your useing the cool-n-quiet features you wont be able to use AIBooster)
so for those of you not useing AIBooster just reinstall the driver for the unknown device from the device manager and point it to your AIBooster install folder-Acpi-win2000 or Acpi64-win2000 if your running a flavor of 64bit windows this will install the acpi driver correctly and now you wont have the unknown device in device manager :)

now on to the complaints and questions :)

I updated my motherboard drivers from 6.39 to 6.53 and promply lost my nvidia nic and killed the nvidia firewall, no ammount of uninstalling and reinstalling would fix this problem as long as i installed the nvidia firewall, so after finaly getting desperate and running driver cleaner to remove any traces of the nvidia drivers my computer wouldnt reboot, well at least the nic and firewall issue was fixed :)

this was a good opportunity to do a clean install of windows again, besides i have nothing better to do with my time than screw with my computer instead of use it. This was also a good time to flash the bios to 1006 too.


Now the question is:

Now that im running a clean install of xpprosp2 and the latest drivers 6.53 / 71.84 and bios 1006 ive taken a rather large hit to performance, ntune used to be able to clock my memory to 440 at stock voltages and latencies now it doesnt seem to be happy running it above default, my 3dmark05 score has dropped from 6767 with my pair of 6600gt's down to something in the 4500 range.

Has anyone else noticed a performance drop like this with the updated drivers / bios ??

ill go back through the bios setup and tripple check the settings there but im pretty sure i got every thing reset after the bios upgrade....

What is the quietest and best heatsink out for this mother board? I have the beetle and its big and loud.

Can anyone give me suggestions?

The beetle runs at 4100 RPM on high and can cool my CPU down to about 35C. If it runs on low the RPM's are around 1600 but still loud due to the 90mm fan it has.

Is there something smaller and quieter out that can cool my CPU?
