Weird A7V133 overclocking

[DragonFire]

Specs first I guess

Asus A7V133 w/raid
Tbird 1.4@1.58 (1.85 volts)
786 megs of PC150 ram
GeForce3
SB Live Value
Windows XP Pro


For some reason I cang et my fsb past 144mhz stable, at 145/146Mhz...XP will load but my geforce goes into that wonderful everytime I open My Computer. My computer wont even boot at 150Mhz, I know its not my ram becuase iv ran my memory at 153Mhz before.....

I tried something new today. I tired 5.5x150Mhz = 825MHz and guess what! my computer started! I got my computer to start up using a 150MHz fsb all the way up to a 6.5 muiltplier and 7+ makes the computer not even post.


Why wont my computer start up using a 150Mhz fsb with a muiltplier setting of 7x or up?

Just a thought here, but are you sure you are setting the bridges correctly on the TBird? Thinking you are setting it at 7.0 and really it's 10 or more?

First, I use the bios to change the muiltplier but even when I use the jumpers which I know im setting right, its the same thing

Do a little searching, iirc their was a problem with the board trying to boot at the fsb speed using the original multiplier not what was set by the bios.

It could be bios related. Have u update to the latest bios ? & tht Sb Live card on slot 3 ? Wht PSU u r using ?

Im using the 1007 bios, the sb is in slot 3 and Im using a Enermax 430watt ps

Maybe u wanna try
1. less agressive timing (CAS3) for the RAM (I know ur RAM can do 150 FSB@CAS2...just try if it help).
2. O/Cing w/ just 1 stick of RAM first. (sometime more than 1 stick of RAM caused some probs).
2. I/O voltage at 3.4-3.6v
3. If u have O/Ced ur VGA card. Back off to default.

I can do 145 FSB on my mobo w/ a Duron800@994.

1) the CAS setting doesnt matter

2) Using just one stick doesnt matter

3) The I/O voltage can be 3.3-3.6, it doesnt matter




I think you missed the point.


My computer will not boot up using a 150MHz FSB. I tired using the lowest muiltplier which is 5.5 with a 150MHz FSB and guess what my computer booted up and started Win XP.

Now I tired every muiltplier from there up and it started at 6.5x150Mhz, however, it did NOY boot up at 7x150Mhz or higher....


During all this time all 3 memory sticks were installed and running at CAS2 with 3.4 I/O voltage.


I did try just 1 stick on ram and cas3 with 3.6 I/O voltage and nothing mattered at 7x150Mhz and up....

My Asus A7V133 will boot at 8x150fsb but there are errors burning cdrs..files get corrupted the max fsb for my board is 146....

nealh, can I get some system specs please......and how do you set your muiltplier, by bios or jumper?
