T-Bird 1.1Ghz / KT133 Chipset -- When I go over 110FSB the board defaults back to 100 on boot..?

[Nighthawk69]

Hey there...

I have a T-Bird 1.1Ghz and an MSI K7T Pro mobo that runs the KT133 chipset. I have finally been able to get it up to 1210Mhz stable by updating the BIOS and upping the voltage. But, when I try to change the FSB over 110Mhz, save the settings, then boot, it goes back to 100FSB at 1100Mhz. Why is it doing that? I'd like to see if I can go higher but it keeps changing itself back!

Any suggestions are apprecaited! I have tried upping the voltage a bit higher and that didn't fix it, but I don't want to go any higher than 1.85 on the core (it's at 1.825 right now).

Thanks!

KT133 Chipset is not a good FSB overclocker, count yourself lucky to get 110.

Hehe, sorry, I'm no longer lucky I can run Prime95 stress test for hours without problems, but as soon as I start up Ghost Recon my USB devices stop working. Any idea what might be causing this? I assume it's simply the higher FSB and the chipset doesn't like it...

If I remember correctly 104 - 107 was the average FSB overclock for the KT133.

at 103 my modem acts all screwy, i'd love 110 stable

my default 850 runs at 10x100 so not too shabby.

Yeah, But that's only 1144 to 1177, which really isn't worth it... :disgust:

Well, it looks like I can get 107Mhz FSB stable at default core voltage... I haven't had any problems with it... yet...

That only puts me at 1177Mhz from 1100Mhz stock, but that's better than nothing if it remains stable.

How about increasing the multiplier? The FSB limitation is the chipset (KT133) not the CPU.

This board does not have support for changing the multiplier. The MSI K7T Pro-2a does, but not the K7T Pro.

Thanks!
