I just loaded the 1007 bios and I'm not impressed. Changed my CAS Latency from 2 to 2.5 with the settings at auto. Curious to hear others results with it....

In trying to tweak the performance of my system, I am getting lockups occasionally. Can anybody suggest what I should look at reducing to minimize lockups?

What did you do to provoke lockups since your stability was fixed?
The video cards?

>> Re: Asus A8N-SLI FAQ
Following your guide I have overclocked the video cards, and I ran the "AutoTune" thing in nTune. The video card piece ran great. I consistantly get 415/1.08 on one card, and 410/1.08 on the other. I've been running them at 405/1.07. The strange thing is that every time I run "AutoTune" process in nTune it gives me different results. Originally, I was getting lousy performance. Then I change the HT multiplier to "Auto" in the BIOS. Even though we changed it to 3x manually in the BIOS, the nTune app was showing it at 2x. After I changed it to "Auto" in the BIOS, it shows at 5x in nTune. The results I get when I "AutoTune" in nTune vary from 402MHz - 450MHz for the Memory Bus, and it always comes up as 2975MHz on the PCI Express Bus. I've tried lowering that to 2,500MHz, but it doesn't help stability at all.

After a bunch of trial and error, it seems like the Memory Bus is the culprit (though it could be the HT multiplier I guess). I set mem bus to 400MHz, the PCI Ex Bus to 2,500MHz, and the vid cards to default. It ran fine. I upped the GPU core bus to 405MHz again, and it ran fine. I upped the GPU mem bus to 1074MHz, and it ran fine. I upped the PCI Ex Bus to 2975, and it still ran fine. So then I started messing with the Memory Bus. 450MHz is horribly unstable. When I ran the "Auto Tune" again, it came up with 430MHz. That seemed stable at first, but still crashed. I started working my way down from there. My next test will be at 412MHz. I'm a bit leery of continuing to test though. My last test (414MHz) locked up my machine like all of the other tests, but when I rebooted, chkdsk ran and I had a bunch of file and directory corruption. I just spent the last three hours trying to get Firefox to run correctly again on my machine.

Originally, I was using 3dMark 03 and 05 to test, but I found that they don't always show up problems immediately. I've had a few times where I'd run at a speed and it would work great in both 3dMarks. Then when I'd try a game, it would lock. I got to the point where I'd change the mem bus speed and fire up World of Warcraft. It generally locks up within a minute or two in WoW if it's going to lock up at all.

FWIW, now that I'm running my mem bus at sane speeds (430 and below), the only problem I have is lockups. At 450MHz, I'd get BSODs. At these lower speeds though, it just locks.

BTW, I haven't changed the memory timings. I'm still using 2T, 3.0, 3, 3, 8 with Corsair Twinx1024-3200C2Pro.

Try these settings

Jumperfree Config
Memory will be 212 MHz if you set the FSB/HTT to 424 MHz (Recommended)
RAM Voltage 2.8 V
CPU 1.5 to 1.65 V
PCI Synch AUTO
HT Multiplier 4X in CPU config
RAM 2.5 - 3 - 3 - 6 1T in DRAM config
Video to the point of no corruption.

So now that you've experimented with nTune you now have a good idea as to what the windows optimized settings are. These figures are the basis for tweaking which is what you need to do now, and it can take weeks before you find the right combo.
On many occasions I've mentioned to create a system restore point prior to overclocking, this should have brought you back to a working (ie; software) condition.

Yeah. You're right. I screwed up. I won't forget to do that again. ;)

Hi all,

I am having an interesting problem with my video card (or motherboard, not sure). Let me just say first that this problem happened before I did what the FAQ said and it still does it even after I followed the FAQ. I have even tried a lot of the solutions in this thread but still have no success (like taking the battery out, reinstalling windows, removing the sound card, etc).

Anyway, here's my problem:

My computer boots up fine and gets into WinXP fine when I don't have the display drivers installed and I may use my computer (except play games, of course). However, when I do install the display drivers, the computer boots up, gets to the WinXP load screen, but then the display goes blank. I know Windows has loaded because of the start up sound I hear, but my monitor is blank (like it goes into standby) and I can't do anything else but restart and go into safe mode to uninstall the drivers.

I built this computer myself on Monday (April 18th). I have contacted ASUS but they just said to make sure the chipset drivers are installed (which they are). I have also submitted a ticket to ATI but I have yet to hear from them (the ticket is in the "Work in Progress" state now).

I appreciate any help you guys can give me, I'm quite frustrated with this.

My Specs:

Asus A8N-SLI Deluxe (BIOS 1006, nForce 6.53 drivers)
AMD Athlon 64 3200+
1x ATI Radeon X850 XT PE PCI-Express (I have tried the new 5.4 drivers and the drivers on the CD)
2x 512MB Corsair 3200XL RAM
Enermax 485W 24 PIN Power Supply
Sound Blaster Audigy 2 ZS Platinum
SUN Microsystems 19" CRT monitor
Windows XP Professional Service Pack 2

Ugh. Lockups galore. I tried your suggested settings and it locked up no matter what I did. I went back to what was stable before and stock clocks, and it still locked up. I checked system restore points, and found I had one from Thursday. I restored it, and I've got some stability back. I then went back to your suggested settings:
RAM Voltage: 2.8V
CUP Voltage: 1.65V
PCI Synch: Auto (was already set there)
HyperTransport Multiplier: 4x
Ram timings: 2.5, 3, 3, 6, 1T
Memory bus: 424MHz.

It ran through 3dMark03 and 05 without a hitch. However, when I tried WoW I got a blue screen several minutes into it. I knocked it down to 422MHz, and it ran through 3dMark03 with a 19901, and 3dMark05 with a 9061. Pretty good. It seemed pretty stable (I tried a bunch of graphically intense games without problem), but then it locked up in HL2. Am I right in turning down the Memory bus to try to find a speed that will minimize lockups, or should I be looking at different settings. Ugh. I just realized that when I set up the 422MHz trial, nTune had reset the memory timings to 8, 3, 3. Now I have to test it with the proper settings.

i got a Fortron Bluestorm 500 for $80 US at Newegg. I have since replaced it with a PC P&C 510 SLI because I was approaching max on the Bluestorm w/ 2x6800GT's and everything else I have running. Anyways, it recieved good writeups on Tom's Hardware, and other places, and provided me with great service. I plan on using it on my next system. Quiet too.

>>>When you install the drivers unplug the monitor and plug it back in to see if you get a monitor message of any kind such as out of frequency range or something.
>>>Use earlier versions of video drivers.
>>>I guess your SLI connector card is in single mode and you tried dual?
>>>Did you clear your CMOS after every change you made?
>>>Install the drivers in safe mode.

Just a few ideas.

Mike,

Thank you for your reply and your suggestions. Unfortunately, the problem still persists even with those suggestions. As for the monitor, it says "Invalid Sync" when the monitor goes off or into standby.

FWIW, I've seen that "frequency out of range" message on my monitor too. I only saw it once though.

When the drivers are installed and you lose the display and then you boot back into safe mode;
>What does the Device Manager say under Display adapters?
>Right click on the adapter > go to properties > then the driver tab > list the info for me.

We'll get to the bottom of your problem, eventually!

Are you a Bluestorm 500? How much are they in the UK? I think you'll b satisfied as it is a well made, quiet piece of gear that looks good and provides clean power for a reasonable price.

I am having problems installing windows XP pro. Below is my configuration. I flashed my bios to 1006 successfully. I am able to create the RAID-0 setup for the WD drives. The bios sees the plextor drives that are connected to Port 1 and 2 of the silicon SATA controller. I used the makedisk.exe on the disk provided with the motherboard and created the nVidia RAID drivers floppy. During installation, I press F6. I install the nVidia RAID class driver (required) and nVidia nForce storage controller (required). The installations starts going through its stuff loading drivers. After a minute, it will say "Setup is starting windows" and than I get the big blue screen. I get a stop: 0x0000007B. This makes me think something is wrong with the drivers. Any suggestions? I am lost on this one.
