| Hi Wiz, I have hit the skids of my overclocking ability at 342 x 9 =3078mhz. But my PI speed dropped to 17.992secs from 17.948s at 333 x 9 = 2997mhz? Why would this happen? Strange eh? My PC won't post past 342 FSB and I am a loss as to why. Everybody else with Q6600 seem to get much more out of it? Any Ideas? Thanks, Mitch.

Have you ran it a few times and after a reboot? It's normal to get varying scores. I run it a couple of times after a reboot to see which is best.  Could your NB have changed it's fsb strap and slackened its latencies to compensate....?

well i would imagine that the mobo is most like the problem here. a google search flagged it as a G31 chipset and if that is right then it is unlikely to be much of an overclockers board.
it is possible the NB has lowered its strap as mentioned earlier or it may just be the case that the slightly increased speed isn't as stable as you think - it may need a higher voltage on the NB or the RAM so they can cope.
also if your board is alright for a higher FSB sometimes lowering your CPU multiplier and going for a higher FSB can get you better results and higher frequencies although i doubt this will work on ur board.
the P45s are coming out soon - might be worth a look out if u want to get a higher overclock the Asus P5Qs look pretty good and are loaded with features and overclock well by all accounts.Tatos

Thanks for the help chaps, but I think you are right, the chipset is pish and I have tried playing with the multiplier (resulting in a few CMOS clears as it wouldn't boot) and various other things, but this MB simply refuses to push my Q6600 over 3.1ghz. (which is a 30% overclock, so I shouldn't grumble too much) It stings a bit when I see people get 3.6-3.7ghz. But hey, it's a bonkers fast PC compared to my AMD 4200 x2 and my video encoding time has halved, which is a splendid result. I will research my MB a lot more when I next upgrade, which will not be soon as I have another nipper on the way in 2 months!  One quick question though before I start encoding again, which test in Orthos should I run to check it is 100% stable. I don't want to be destroying blank DVD's by having it bomb half way through?

As you say it's still a beast with 12.4Ghz of power...

i believe Large FFT for CPU and blend for system testing is what a quick google came up with and it seems to ring a bell from when i overclocked my main rig.
also congrats on the latest addition, to be, to your family!Tatos
