Iedereen zegt wel dat het Asus bord zo geweldig is maar als je bij de newsforums van Asus gaat lezen kun je zien dat er heel veel mensen zijn die problemen hebben om het bord stabiel te krijgen. En ik heb er helaas
ook ervaring mee want ik heb ook zo'n 'geweldig' Asus bord. Ik heb gelukkig hem eindelijk een beetje stabiel gekregen en dat heb ik gedaan volgens een bericht ook gepost op de forums. Ik zal hem ook posten ik hoop dat de gene met een instabiel bord er wat aan hebben. Ik zelf trouwens heb een:
A7V Installation Tips.
CPU Heat Sink Installation.
Make sure the FAN is sucking not blowing on the HS!!! (alpha type coolers)
Chasis Fan Installation.
1 x 80mm fan blowing in installed at bottom front of the case.
1 x 80mm fan blowing out inatalled at top/middle back of the case. (Power Supply unit that have daul fans are nice).
I found that this will reduce the tempature when cpu is idle.
Change this is the bios.
Advanced -> Chip Configuration -> Master PCI Read Caching -> "ENABLE"
Which Bios should you use.
1002 - Higher core voltage setting ie: when you set the vcore to 1.85v it is actually 1.9v
This can be helpful in some situations where overclocking requires the higher voltage.
In my case I could not boot into win98/win2k with bios 1003 and 1004a at 900 becuase the voltage was to low (1.85 instead of 1.92).
1003 - I found this stable but didn't give me the higher core voltage I needed.
1004a - This raised my cpu temp when idle by 10c-15c degrees.
I had the following problems after I upgraded to this bios.
Outlook Express News - lock ups while looking at pictures in newgroups.
Internet Explorer - random lock ups
Microsoft Media Player - lock ups while playing mp3's (think becuase it has that stupid techno screen in it)
CPU temp was way to high when idle 55 C with the previous bios 38 C
I recommend flashing your bois with 1003 or 1002 until asus releases 1004 final.
Where to get the bios.
Flashing the bios.
Use "C:\Program Files\ASUS\AsusUpdate\Update.exe to install the file once your uzip it.
Remember after flashing bios.
Enter the bios after the reboot and load setup defaults, then reboot.
This fixed my sound blaster live problem.
First install the sound card into pci slot 3.
Make sure you are using the lastest drivers.
Put the following setting in the BIOS setup menu.
Advanced -> PCI Configuration -> PCI/PNP IRQ Resource Exclusion -> "IRQ 5 Reserved for Legacy Device" -> "Yes"
My ide setup is as follows and I did not have problems installing win98.
IBM ATA-100 drive on Primary ATA-100 channel
Asus 40x cdrom on Seconday controler as slave.
I did have problems installing win2k the problem was that it couldn't find the hard drive.
Win2K requires the promise drivers to be loaded.
When the screen comes up and asks you if there any thirdparty mass storage drivers to be added.
You must before hand download and create the promise driver disk.
Then must specify a mass storage controler and put in the promise driver disk.
Other things that I should mention.
I have a Geforce2 card from Asus.
Asus recomends installing the via-4in1 drivers in normal mode and not turbo.
This means that AGP 1x and 2x is available but not AGP 4x.
Nvidia also say that using sidebanding will cause instability. I flashed by card so that it doesn't use sidebanding (SBA)
Fastwrites Setting in the bios can also cause instabilty.
Optimal/Normal setting in the bios can also cause instabilty.
If you don't have problem with crashing during video games don't touch anything.
If your system is rock stable in os but crashes in video games try this.
In the BIOS.
change Advanced -> Optimal -> "NORMAL"
This setting changes AGP to 1x when normal and 2x optimal, if you've installed via-4in1 driver in turbo this setting changes AGP to 2x when normal and 4x optimal
change Advanced -> Chip Configuration -> AGP Fastwrites -> "DISABLE"
Install via 4in1 again with "normal" checked and not turbo.
If you have tried all these AGP setting without solving the problem. You more then likily have the same problem as I.
How I got rid of it.
I underclocked the bus speed(100) to 95 fbs from the bios.
I have not tried AGP at 2x or 4x with the FBS at 95 but for now the system is now totally stable while playing video games. Though I have tried upgrading my bios to 1004a and then I start having problems.
Don't know if I forgot anything but if you are having as many problems as I have had you may appreciate this.
btw my system
A7V rev 1.01 (bios 1002)
Alpha Pal cooler
1 stick of Corsair Cas2 133 Ram
Asus v7700 32 pure (AGP 1x Latest Bios without SBA Lastest Drivers)
IBM Deskstar 15G (ATA-100)
Enermax 350W w/Dual Fan PU
Dual Boot win98/win2k
CPU under Full load 56C-58C
seti screensaver average wu time 8 - 8 1/2 hours
I am sacrafising perforance for stabilty now. But..
Hopefully the FBS and AGP 4x stabilty will be eventually solved with the via-4in1 drivers. But this has not been addressed by the newest ones 4.25a
Hopefully the newer MB bios will allow the higher voltage as in 1002 and also allow diabling the ATA-100 promise controller.
