For anyone that is overclocking out there

[HeroXx]

I have had a few problems whilst overclocking, I can't boot into Windows Vista at any overclocked speed (changing the fsb and adjusting the voltage) it just gets stuck on the loading bar on bootup.

Also I can push it to around 1440mhz on my motherboard but as soon as I set it to 1450mhz it will not boot at all (blank screen have to power off then boot again) I have read loads of tutorials and all seem to make it look so easy as to just change the settings and boot it up..

I have an Intel C2D E8200 and the Motherboard is the ASUS P5N-D.

I have been doing it by Unlinked frequencys so I am leaving the ram along, it just seems strange that it won't boot at all at any adjustment of the frequency and the 1450 barrier muffles me too.

Ok is there ram unlink option that you have changed in the bios, if not then the ram will overclock automatically, What are your ram settings and fsb settings in the bios.

[HeroXx]

I said that in the post :) I am using unlinked and the FSB and RAM are standard at the moment.

Like I said in the post I can't overclock it at all, Windows Vista will not boot with any change to the settings. Every time I have overclocked it I have left the RAM unlinked at 800mhz.

Ok sorry it's been a long day ;) What are the vcore volts set too? What is your normal vcore setting and what cooler are you using, sorry just trying to get a picture of all the components. I'm not upto speed on the 750 chipset, apart from its just a revised version in the 650, so my automatic thought is your mobo is holding you back the older nvidia chipsets are notorious rubbish overclockers of quads and newer cpu's

I have a Zalman CNPS9700-NT NVIDIA Tritium, Cooling isn't a problem as it sits at around 30 - 35c idle.

I thought it might be the vcore so I jumped it from autmatic to 1.25 to 1.3 and 1.35 no effect on the problem.

It is probably the chipset I have probs with my nforce 4 with good old x2 3800 from 2.0 to 2.2

Bump the NB voltage to 1.4 ish and see if that helps.

[TheMadDutchDude]

Maybe that is the whining sound on my computer? The NB... I don't want to put it up though as I do not have the money to replace it if I screw up :(

[Asce]

Thats why there is aftermarket cooling. Look at the Thermalright Hr-05 SLi. An old AMD CPU fan fits on the perfect.

[Jonny2Bad]

Ok what does cpuz say your actual vcore is most asus boards have a droop in voltage mine has a .6 droop so when its set at 1.4v on bios it actually is running at 1.34v. But i doubt it is this more the rubbish nvidia chipset. Intel chips work better and oc better in intel chipsets.

Ok..... dummest post on the forum!!

Just what is the benefit of over clocking? What can you actually see/feel different? What damage can it do?

Please be gentle lol

Thanks

Well you can turn a cheap cpu into a very expensive cpu, when the 1st e6600 came out ppl were getting them upto 3ghz in a heatbeat, when intle were selling 3ghz dualcores for more than £500, the risks are minimal really as long as you follow the guidelines, and yes if you can only afford a £80 you can turn that chip into a £200 chip easily. Got to be worth it :wink:

It does look like a VCore droop problem. HeroXx.

Good O/C guide here:
