MSI K7T Pro 133 mHz FSB

[ksoth]

I have a Duron 700 on a MSI K7T Pro mobo. Now, the most recent 1.8 BIOS upgrade gives support for a 133 mHz FSB. Obviously my chip is supposed to be at 100 mHz, but that's no fun. Well, when I go into the BIOS I change the CPU Host/PCI Clock to 133/33, save it and restart. But, nothing happens, it just resets the FSB back to Default, which is 100/33. If I set the value to like 105/35, it boots up as a Duron 735 mHz. Before I had my chip at a 110 FSB speed for like 770 mHz, but I had stability problems so I stopped that. Anyway, a 133 mHz FSB would make my 700 a 931 mHz, so that'd be cool. Anyone know what I can do to get this working, if possible at all? Thanks.

There is one thing you said in your post 110fsb made your system unstable. this could be your ram, procecor, or the mobo chipset. if you have pc100 ram it may not be able to handle more than 110 ect. Also, the best way to o/c the Duron is via multiplyer change of the procecor.

dont know your motherboard. but does it support changing the multiplyer? best way to o/c an amd chip

That Via chipset is not known for its 133MHz ability for sure. I think that the 133MHz option is wishful thinking on your mobo's part. I doubt you could get over 107MHz with it. Go with the multiplier and like 107MHz.

well that would be quite an overclock to be sure.
First of all you need to unlock the bridges of your cpu.
Next of all set your system to run at 5.5 X 133 ( yes lower the multiplier) then run your tests to check for stability. This setting will give you quite a bit of improvement over the stock (700) speed for more reasons than the addtional 33 mhz gain in cpu speed. If that proves stabil then try 6.0 x 133 and move your way up slowly. When you overclock you should do it a little at a time checking along the way each increase not just wham expect to go from 100 to 133 without first lowering your cpu clock. When you find that the chip is running a bit unstable try upping the voltage a hair and this usually will stable it. Remember there are limits and if you fry your cpu you are now the proud owner of a duron keychain.

A little bit of knowledge is a dangerous thing!

That's just the thing, my motherboard doesn't support multiplier adjustments. If it did, I wouldn't be in this predicament. So, if I wanted to change the multiplier settings, I'd have to cut and join not just the L1 bridges, but all of the bridges on the chip to get whatever multiplier setting I want. That's just too much work and that increases the risk of me damaging the CPU with all the heatsink removals and reattachments. I'm thinking that the main reason it keeps resetting back to default is because the chip itself can't handle 931 mHz. So, if I don't just go out and buy a new chip, I think I'll overclock this one by changing the multiplier to 6.5 instead of 7, then increasing the bus to 133. That'd give me a nice 865 mHz chip, which should work considering everything I've read on overclocking Durons. I just think the 931 is a bit too much for this one to handle... And If I fry the chip, it's only a $60 mistake (even though I paid $150 for the chip when I bought it a few months ago. EEK!) Thanks for your input.

Have you done anything to up the voltage a wee bit? If that does not work a new mobo may be needed to curb your urge to overclock ( yeah I know $ but hey you know you want one!)
