My 939 X2 4400+ just does not want to let me OC to anything over 2.6GHz (237x11). I am trying to get to a 246x11, but my rig just reboots. I lowered the RAM to 133MHz which is a 2:3 divider and it still won't work. My HT is 3x.....any advice because I think that this may be all I will ever see as my final OC.
 
wot voltages u using? i managed to fix my 4200+ ocing by just upping voltages to 1.475 and i can get it running at 285x9.5 (2707) with 1.5v but it seems to make my super pi result go from 33sec at 290x9 (2610) to 42 sec :( try upping ur memory voltages i got my corsair pc 6400 runnin at 2.1v
 
Boyo, what timings are you using on your memory? If you are going above about 235, you may need to try 2.5,3,3,7 or even 3,4,4,8 timings. Also, set the memory voltage to about 2.8v or so.

Degen, my guess on your Super PI issue is you are seeing a drop off from going to a .5 multi and running asynch. What is the stock multi on your CPU?
 
200x11 ill give an equal number multi a try then cheers - seems to have worked thanks and just read ur sig - wot voltage u recommend setting Corsair 1GB DDR2 XMS2-6400C5 TwinX (2x512MB) at? would setting it at 2.1v be holding my oc back ne more at the moment?
 
a 4400+ @ 2.6ghz is a good mark. you probably should be happy with it.

They are covered by warranty up to 2.1v and I can't officially recommend higher than that. Anything above that may or may not be productive but would void the warranty. Lots of people are doing it but, that excuse never worked with my parents either.
 
My RAM Timings are 3-3-2-6 T1 and my Vcore is set to 1.35, although it reads 1.44V in CPUz. I'll try and up my Vcore and see if I can get higher. Thanks for the tips.
 
Okay. So I upped my Vcore and it is now reading 1.472V in CPUz. My RAM is still the same timings but running at 225MHz, a drop from 237MHz. Which benchmark should I run to see if the OC is stable?
 
Lots of people like Prime95 and since you have a dual core CPU, run 2 instances of it. Each core will run one instance and you will get a good idea if you are stable. Also, if you are a gamer, play your most demanding game. I have seen machines do Prime95 very well, yet fail to run a game without crashing.
 
Well my rig fails at 246x11. Even with the vcore increase. Looks like 240x11 is my limit.
