D0 Stepping = BEAST OF A CHIP

I've collected a few benchmarks and reviews comparing application performance with HT on and HT off. The results are varied. In some cases, HT improves performance, but in other cases it decreases performance.

Thus, as far as I'm concerned, the benefit is inconclusive. I'm leaving mine on though :)
 
So with a 9.3% avg gain, one must weigh up the options. Can you get more than 9.3% extra clocks with HT off.

My guess would be, for now HT off, for in 3 years time when software catches up, HT on.

Higher temps = shorter life. HT adds 12 deg. Simples.

Tell me, If you truly believe temperature plays no part in the death of electronic components, WTF are you using a water cooling loop for ? Why do intel supply HSFs? How do scythe stay in buisness? And thermaltake, how the hell did they grow so huge ?

My wonderful pieces of information seem to have built many many multibillion dollar empires.

Absolute rubbish.

Processors aren't LIGHTBULBS!!!!

Processors are designed to last many years at high temperatures. Yep, that's why there is a cooler on top of it!!!

When did you last see a chicken in the over wearing a fan?

The point is there is no specific correlation between MTF and heat of the chip. It would be common sense to assume there is a link. But not the direct one you are implying. No disrespect to yourself but your thoughts are merely based on fear of burning the chip with zero information to backup what is basically an ASSUMPTION.

The Intel guidlines themselves say the chips can run at 80c+. 100% loaded for extended periods of time.

If your chip breaks it will be due to a manufacturing defect. Not too much heat. Unless your talking silly temperatures of 90c+. In which case Prime95\etc would just fail anyway.

Chips aren't worth any money anyway in 2-3 years so if they break then...Who gives a rats bottom since they will only be worth £50 tops.

Depends on what you use your PC for. For me... I see a huge performance boost when encoding video with HT enabled for example. However. for gaming little or no improvement. Horses for courses I guess.
 
Your analergies are all wrong too, and are simply blanket generalised assetions that mean nothing when dealing in specifics. Overclocking to any decent degree is a specific.

For example, the Core i7 chips normally hit a wall not because of heat but because of an innherant "hard wall" in the chip. Some chips from past generations fall over almost purely on heat, for example the Athlon Thoroughbred B 2100+ chip was an overclockers dream. If you kept it cool, it could go nearly anywhere.

Every chip has heat limit and I'm not saying the Core i7 chips don't have one, that would be silly. I'm saying that you shouldn't make assertions based on limited knowlege, hearsay and, well it sounds cheesy but "fear".

On the subject of companies making premium coolers etc, well that's an easy one. If you go over a certain voltage it will come to the point where the stock cooler will not just make the temperatures higher. But will actually be incapable of keeping a lid on the temperatures altogether.

For example. I used to own a VapoChill Lightspeed freezer cooler thingy, it would hold chip X at -35c, no matter the voltage up to a certain point where the heat output would be too much and it would just get hotter and hotter up to -10c which is not optimal for that cooling unit.

...Think of it as trying to carrying too much shopping in your arms with no bags...Then dropping the LOT!

Here is a little pointer to help you through the rest of your life; go get a basic education.

When you are finished in several years time, and you come back and agree that there is indeed a link between Heat/Chemistry/Physics.... well maybe i'll forgive your ignorance.

Go do some reading.
 
Wow. People are pointing out issues and making valid comments?
Reason enough to belittle their statements?
You only have a few posts, I suggest you read the FAQ regarding forum conduct and ettiqute to other users

If you read again you'll see that any poor etiquette from myself is in direct response to inflamatory posts.
 
Don't rise to it then, there are long established members who are making valid comments, all of which are being instantly dismissed in a way that is generally unacceptable on these forums. A post about hardware has turned into slanting match. Your original post asked for help clocking further, something that would yield higher temps. If you ask for assistance and people offer advice then why neglect advice that you, yourself have asked for? :confused:
 
I dont think it was the OP's intention to seek help overclocking further.
He just wanted to post showing his low vcore/temps at 4.2Ghz.

When he was brought to task for not having HT enabled rather than congratulated on his 'achievement', he cut up rough.
