FSB resetting w/ 2.0A after going past 120mhz

[BeAsTy]

I'm oc'ing my 2.0A w/ a july pack date, on a Chaintech 93jl1 845E, the motherboard resets the fsb to 100 if i try and set anything past 120mhz fsb, it can't be my board as it did this on my MSI 845G Max board before. Think it's my proc buggin out?

Using OCZ 512 pc 3000 cas 2 2/2/5 timing (the board locks @ 3:4 or 1:1) [tried making timing slower, same problem]
Stock HSF w/ AS3
Good case air flow

id say its the board then.

try a new bios?
more vcore?

on both boards i had it run w/ a 1.725vcore, on 120mhz it'll only be stable w/ 1.675 or more... i haven't been able to get it to boot 121+ w/o it resetting to 100... weird... i'm goin to get an asus p4b533-v soon.. hopefully that'll be more merciful to me, but it only confuses me because it did this on 2 different boards..😕 if it helps, mbm and the bundled monitor prog reports only 1.6v on core even when it's not on load and set 1.725

*bios is newest on both boards

oh im sorry i read that entirely wrong.

lets try this again....
do some stress testing ~ prime95 & memtest86.
work your way up the fsb til it just cant go no more even when adding voltage.
it is very possible it is the chip maxing out.

Yea, only feels weird since i can go perfectly stable @ 115fsb only @ 1.6v, can't even boot past 120 w/o resetting.. <shrug> gonna try and yoink my bud's 2.0A (we bought ours at same time, but he doesn't oc ^^) and see if his can go past 120 w/o resetting

 

[THUGSROOK]

yea thats about right...

my 1.6A can do 155fsb on default voltage.
but for 166fsb it takes 1.7v.

I have found as soon as it needs a bit more juice then default it usually only has 200mhz of total clock speed left before it is even unstable a 1.7v...With a 2.0a that would be about 10fsb...Since you were running 115 but needed 1.6+ v that may be the cpu...

Turn off halt on all errors in the bios....see if that helps...It sounds like a mobo protection thing. some boards just don't boot idf you go too high and requires shrting the cmos plug to reset it...It is basically doing it for you!!!
