That helps :)

BTW did you check the links I provided???

UPDATE:

After resting the BIOS to the default factories settings, I thought I would try again.

I used Clunk's tutorial from Core i7 Overclocking Guide For Beginners

I followed as he has stated but could no longer use 1.25v when i got to 4Ghz (where I am now)

I have found what i think is a suitable setting. 1.288v @ 4Ghz (190 x 21)

I have C-State ON, i regular wonder off and leave the computer on for a few hours, so why waste money and energy and always have a hot computer when i can let the processor rest when i'm not using it?

I also have Hyper Threading ON.

Now, i did 15 passes of the IntelBurn Test. It passed no problems with temps peaking around 78*C and 44*C when idle (I have not got a very good cooling set up atm due to the computer case is half broken). I thought Cool, so i thought i'd let it run at 100% using Prime95, i used "Blends" and after 5 minutes, i got a BSOD. So i upped the voltage to what i have now, 1.88V's and still had the same problem after 5 minutes.

Why is this?

I say i "think its stable" because i don't know what program will use all 4 processors at 100% for over 5 minutes?

Thanks
Dan

Proving once again what I have been saying about Prime Blend all along. It's the real deal for stablity testing. 5 minutes of Prime blend and you are far from stable my friend, not even close IMO. 10 hours of Prime Blend and you will have something. It takes a lot more than Vcore adjustments to get a system stable.

Ah. I give up. It works fine now, PCMark Vantage works fine on it and all is ok.

Anyone willing to meet up to tune my processor. Monies waiting.

Those fans will run between 700-900 RPM with the LN/ULN adapters if used.

I don’t use them as I find that even with the fan running at max speed it’s plenty quiet for me.

Thanks.

Ditto. They're good if you are going for ultra-quiet setup (like a pure HTPC etc) but even at full tilt, the noctua fans are nice and quiet.

nah mate, don't give up. Just take a break - read a bit more and you'll be tinkering again in no time

It's quick and easy to ham fist a working OC - but it takes time to refine.

As for 'stability' - when overclocking, there is no such thing as an absolutely 100% stable system. However you can come pretty damn close

Every overclocker has their own methods and tools that they use. Usually it's a battery of tests. It comes down to personal preference.

Often, you can start with 'loose' RAM timings to dial in your CPU O/C - then once that's sorted, you move on to 'tightening' the RAM. ( potentially eliminates initial RAM or vcore issues)

Generally, apps like IBT, LinX etc are good for 'quick and dirty' vcore testing. Make an adjustment, run for 5 passes - if all good run for 20+ etc.

Then you move onto Prime95's blend (torture test) if that passes the 12-24hr run and you have already passed IBT, LinX etc - then you are pretty much good to go.

But if you fail on Prime, then whatever FFT test you fail on gives an indication where the problem may lie. Low FFT failure is generally vcore/CPU related. Large FFT points towards RAM.

(However it's worth noting that some can pass IBT but fail Prime, or conversely pass prime but fail IBT etc)

The last and most important test is simply real world usage. If you have minimal, or preferably no BSOD's, freezes etc - then you can call it 'stable'
