Could I be having problems overclocking my Thunderbird because I unlocked it with a lead pencil ? As in not using something permanent ?

I used to run my 1ghz T-bird at 1.4ghz and then it started acting up in about a week, so then I lowered it down to 1.33Ghz. Started acting up in 2 weeks. Now I set it down to just 1.2Ghz just to be safe.

Does the new 1.33Ghz AYHJA Thunderbirds have the L1 bridges unlocked by default ? Just ordered one and it's on it's way. I don't want to have the same problem when overclocking it.

That could be a reason. I never had any problems with my pencil trick, but I used defogger, just so I could try and lower the voltage.

hey, smb, i recently did that with ma cpu. the defogger kit/ after getting rid of the pencil trick hoping the same thing, lowering the voltage. and stuff like dat but it didn't seem to work

i'm still at the same ol' 750@900 at 1.850 Core Voltage and 3.50 I/O voltage

I wuz hoping to get some more mhz out but the system just won't boot.
Mbe this 750 ain't too overclockable

ma chip has these markin's

A0750APT3B

Hrm. anybody can decipher this?>
btw, according to the probe on the abit kt7 mainboard, ma system is runni'n (well today's a hot day)
36C and at load b4, i had it at like 42C

Ma system doens't have good air flow, it's at 32C according to this. on this hot day in Richmond Hill, Ontario

from what I've read, all the 1.33 gig chips are unlocked anyway. Also was reading that AMD is investigating that cutting the L1 bridges to lock them may be possibly, cutting down on the life span of them.



the "folding" pimp,

sethpa, that is great to hear. I won't have to do the stupid pencil trick anymore.

I just sold my 1Ghz thunderbird for $160 so I don't have to worry about it anymore.
