as the title says, i bumped it to 1600 fsb and X9 multiplier and well, the bsod says it all. i was downloading 3d mark to test out the new clock speeds when bam! the sickening smurf screen was not welcomed by my eyes. i set the voltage to auto on the motherboard but i think it was running at 1.35, im back to 2.4 now
any help to stop the bsod
cheers
 
Overclock properly and don't use the auto voltage option for one!
Stick it at a lower overclock first and work your way up gradually rather than just sticking it at 3.6? (Not an intel person)
 
as above, i dont think you will have much success with just banging it up to 3.6, some people struggle to reach 3 so going straight for 3.6 is more than ambitious. start at 333fsb and see if that works.

haha ok, what limits an overclock, i always assumed it was just heat and motherboard

Poor clocking chip (even wih insane volts of over 1.6 you may not be able to get a stable clock) heat is a factor yes, chip/motherboard FSB walls, RAM etc.
 
Also it's a good idea to overclock your CPU and RAM separately. When you're finding the max overclock for your cpu make sure your RAM stays well within its rated limits at all times. Then write down your max stable overclock for the CPU, set everything back so the CPU is within its limits and begin overclocking your RAM. Once you've found your highest stable settings for this you can put the CPU back up then choose a memory divider that gets a final speed closest to what you found your RAM. Do some more stability testing, you'll prob need to tweak a little at this point.
Take your time and do it properly is the best advice, all the info you need is on here you just need to read up a bit.
 
Strangely when I was using PRIME95 it passed all tests for many hours but when trying TF2 it crashes if it's unstable.

Yet when stock it's fine on both.

Also having trouble with my Q6600 even getting a small OC yet the previous owner got it high.. :(

Give Prime Blend a run if you haven't already, could be a memory issue.

ok i will do that :D cheers
but why work up gradually ?

I've always beleived in the reverse policy - start high at 4.5Ghz and max voltage in bios and work down gradually until my pc boots.

Then work down futher until it plays one of my games without crashing for ten minutes.

Ignore all the temp monitoring stuff, it either works or it doesn't in my book!

Tongue firmly in cheek with the above :p
 
hmmm i kno wer your coming fro greebo; in my experience your just going to shorten the life of your chip or even break it forcing suck a high voltage on it!
I always start round the 500 Mhz higher mark than stock n move up slowly.

it always works for me!

because every processor is different.. e.g 2 q6600 systems running the same hardware but 1 may only can clock to 3.2ghz, while the system may clock to 3.60ghz.. it just depends how well the cores are...

kool thanks people, i just got sp1 so i think that sorted my 4 gig of ram issue :D

are u running vista 32bit? if yes, then it still won't use all 4gb even though it says 4gb.

Also you might need to bump up other voltages than the Vcore, motherboard voltages, memory, FSB voltage etc, it's an art ;)

To be fair though, it's not a bad policy. I never worry about heat. As long as I'm not putting stupid volts across my chip I just forget the temperature and make it stable.:)

Or, in fact, give your computer the stability test it deserves.

8hrs of Orthos Blend, 4hrs of 3Dmark2k6 on loop, encode a 90min DIVX at 2000kbps, and survive 8hrs of Toast.

If your computer passes all of that, your system can be considered (by me) stable, as you've thrown everything at it as could (un)reasonably be expected.

Orthos is not the ultimate stability test. It provides good indication of correct CPU and -RAM interaction, but that is it. And last time I checked, there is a bit more to computers than just the CPU and RAM.

Too many people get hung up on Prime and Orthos as the only stability tests they need run, yet are surprised when - having their computer pass a week of Orthos blend - their computer falls over when asked to play a game.
