okay after reading many different forums on overclocking (and finding out my mobo is a piece of crap)i thought i would have a go.

If i go past 245 my pc locks up and needs a restart

with my current settings the pc runs ok but it will not start at these timings,if i set it to these timings in bios it wont boot,but once it is running i can change to these settings from windows and it is ok.does anyone know why this is?

 

[llwyd]

booting is fairly intensive. have you run any stability tests within windows?

 

[nepas]

do you mean super pi and prime95?

super pi wont start!!!

 

[llwyd]

what do you mean by wont start? does it fail when you try to start a test? also can you run applications with the overclock?

 

[nepas]

it wont start when i try to run a test,it just crashes to desktop.prime95 will start.

yes i can run apps with the oc. i am runing media player and generals online also i am running azureus at the moment

Looking at your profile you have Kingston value ram. i recomend you use 3-3-3-8 timings. My KVR ran 220mhz @ stock volts 100% stable for a loooonnnggg time.

 

[nepas]

many thanks,i will change that

when i try to run super pi instead of crashing to dektop it now says "not convergent in sqr"

what the hell does that mean?

 

[llwyd]

ive never had a super PI fail on me sooo i cant be sure but i think any form of failure to complete a loop is down to instability. someone correct me if im wrong but i think super PI is very memory dependable so try what ham suggested and up the Vdimm a little

Aye, it pretty much means that the test failed, so either up vdimm (though this may actually hurt things depending on what chips you have, probably fine though) or drop your clocks a bit until it's stable

 

[nepas]

i did try what ham suggested and thats why now it says the sqr bit

could it be that my mobo is crap

its a biostar geforce6100(not the tforce one)

I think you should probably go download one of the 3DMarks (I'd say just go with 03) and then run that. I've found that it is a great way to test stability of CPU, RAM, and graphics. If it freezes at some point, that should tell you that you've pushed too far. So obviously restart the comp and drop the clocks a bit.
