Cannot overclock as high as before

I have a AMD Tbird 1.4ghz cpu with a Abit KG7 Raid mobo water cooled full load at 26C. When i first got the chip i used to be able to overclock it to 1.6ghz with eaz. So i decided to do the voltage mod to the mobo. I did the voltage mod and it was success i booted the computer upped the voltage and it went up to 2.1vcore. So when i tryed to overclock at that vcore i couldnt get anything past 1.5ghz. No matter what i did windows didnt wanna boot. So i desoldered one ends of the voltage mod to see if that could have been the problem and i still get the same results i cannot get the computer to boot past 1.5 ghz. And before the mod i used to get 1.6ghz easy. Whats wrong with it?

Thanks for any information

You know, if that was me, I'd pull off the HSF and make sure all that high wattage overclocking didn't cook the thermal compound a little too dry. Core temperature is a big factor in how high you can OC.

Or it could just be your power supply as well. what PSU to u have? what are the 5V line???

Whats the 5v line reading?

A lot of people have trouble with Athlons when the 5v line goes below 4.8v. Me being one of them! I replaced my weak psus with new ones and have 5v readings of 4.95 to 5.05 most of the time-and no stability problems.

I have water cooling so it shouldnt really get that hot behind the water block. As for the power supply i have a 400watt power supply.

It happen's sometimes and it suck's when it does.
It has something to do with electromigration you can read about what happen's here:

I am not saying for sure this it why but is one possible expanation.
100mhz drop is alot

Hope you get it back.

Well.. I dont know much about 'Motherboard Mods'

But could that have Jumped to much power to the CPU and is slowly frying?

Ontop of all of that..

What kind of 400 Watt Powersupply do you have, IT doesnt matter if it was 5000 watts, The powersupply could be bad PERIOD.

Have you checked that the problem is not caused by some other part of the system. I mean if you lower the multiplier (to 10 or so) can you then raise the fsb as before?
