Q9550 Overclock Problem

Thanks.. that loks very similar to my 3.825Ghz but I have a 1.3vcore and my RAM is at 2.00D instead of B. Does it really make a big difference

 

2.00D is what you should be using, not 2.00B.

 

why is it what you should be useing? it wont be stable when i use the 2.00D

 

It should be, 2.00D is the proper FSB strap for the overclock, 2.00B is the lower strap.

 

well yes thats what yo do to get it stable. i seriously doubt there is a proper strap to use. you use what your comfortable with and what works and what your needs are. just because its the max setting doesnt mean its the correct setting.

 

well, as far as I knew, 2.00D was for use FSBs of 1600 and over, 2.00B was for use with a 1066 FSB. I will have to try 2.00B then as I never considered it before.

 

3.825Ghz has a FSB of 1800, which isnt listed so how do you chose the multiplier letter?

 

I use D as that's the closest approximation.

 

Hey cincyrob, are those settings prime95 stable? I just tried those but at 2.1v for the RAM and MCH core at 1.34. Im currently trying with 1.335 vcore or something around 1.33, cant remember. whats a good 4ghz vcore? 3.5v?

 

1.35-1.40.

 

Yeah I was thinking that because 1.325 seems alittle low...
thanks

 

Ok 4Ghz is IBT and Prime stable at 1.33125v but Im getting some mouse lag once every 2-3 minutes. Is this due to the OC or should i just bump the Vcore to be safe?

 

A truly stable overclock should have no negative impacts on using your PC. You should try raising the voltage to the chipset.
