Well, I think they are doing it again.

I may be fined for splitting hairs here, but it seems that the Intel boys are playing with terminology and consumer manipulation; they are pros, right?

Imagine a car with 4 engines, all powering the same single drive shaft. That would be a truly "quad-engined" car in every sense of the word and would satisfy the sticklers and the rabble. Now imagine a car with 4 engines, but 2 engines power the front wheels and 2 engines power the rear wheels, and the 2 necessary drivers (or one guy having to think about 2 separate events) are screaming at each other over the din in the car. Not really "quad-engine", IMO.

History: Presler "dual core" Pentiums; not "dual-core", but 2 single cores on one die. Dual-core: Again, 2 single cores on one die. Both using the FSB to communicate, and thus, not a truly united set of CPUs.

Now, "Quad-Core". Not really. 2 dual-core CPUs, whacked together on the same die and using the FSB to communicate. Right. Why? Yields, core matching, fabbing and money, a.k.a., time to market.

Well cubanlord, I wouldn't be worrying about your Core2 Duo being put totally out to pasture just yet. At least in terms of honesty and innovation. This is another pass off from Intel to buy time and get some money for the reasons stated above. True Quad-core will come, but it's not quite here yet. As the dual-cores are being manhandled by the Core2 Duo, so the quad core will be kicked around by the Core4 Quattro (Intel, I want royalties for that name), when it does finally arrive.

There is no doubt that the "2 dual cores on a single die" rocks big time and it throws up some really awesome numbers. It overclocks like a champ , shows no major flaws in design or implementation, has plenty of mainboard supporters and is well and truly, mind-numbingly powerful.

It's just not what Intel are saying it is and it's a bit of a ruse.

Get it together Intel. Any circus can hitch a couple of more horses on the wagon.

Go ATI/AMD! Bring in Barcelona and keep it honest.

The final fish-in-the-face? Intel Core 2 Extreme QX6700 = $999. Right.

I like encoding videos for upload and the current dual-core processors still take ages over a 2 hour DVD encode (2 hours most times) so whenever I can get a quad-core processor for around $500 or a little more, I'll think I'll have to splash out along with GeForce 8000 (some time next year) card for Crysis and Bioshock. I want to build my first system with the best components I can find next year.

is there really a big difference between these.. except the price of course

E6600 -Dual (64bit)/2.4G/FSB1066/4MB/775소켓/콘로 W327.000

or

X6800-Dual 2extreme (64bit)/2.93G/FSB1066/4MB/775소켓/콘로
W1.188.500

the price is crazy seems just for .5 more speed..
RIP OFF OR WHAT?

One thing to consider is that the E6400 (207,000 won) will overclock to around 3 gigahertz with just stock cooling. Now, that's at the upper edge of what you can safely overclock, but I'd bet that you could have it run at around 2.9 G with no worries. If I were going to put together a new system, that's probably what I'd do. (Well, to be honest, nothing I do needs that kind of speed, so I probably wouldn't overclock.)

The way things are going for you these days, it's best to leave things be.

I will post back when I have more time, but for brevity and to save some typing, I will link you to some good sites that explain it well.

With certain conditions met, it's not hard, risky or otherwise problematic.

I'm far from an expert on the subject, so I'll let Demo handle it, but I will let you know my experiences with overclocking.

I've done modest overclocking on my last 3 systems with no ill effects whatsoever. Right now, I'm overclocking an AMD 64 3000+ by about 20-25%. It's a very reasonable overclock with negligible heat increase, and no stability issues at all. Oh, and I'm using stock cooling also. For my cpu and motherboard, I just increased the bus speed bit by bit til I got it where I wanted it. If you are keen on tinkering, you can mess around with ram timings and voltages and things like that, but that's a bit beyond what I'm comfortable doing.

There's a pretty good article here, which might give you some idea of what you can expect..

I think it's a no-brainer these days, compared with the way it used to be. (BX boards, Celeron 333A!!)

A good heatsink (yes, the coolers that are being provided these days are good for smallish overclocks), lots of case ventilation and proper monitoring. (Motherboard Monitor)

I have a 90mm case fan in front and one in the back. The front fan pushes in cool air (it's positioned very low in the case) while the back fan pushes out the hot air. (It's located high in the back, in line with the CPU and just below the PSU) This will provide good airflow in the case.

To get rid of the heat created by the graphics card, a slot fan directly underneath the card. They are virtually silent and move a lot of air. A good heatsink (copper) is next, as well as the correct application of heatpaste (super-skin-thin, credit card spread) and proper seating on the CPU heatspreader.

Just think airflow. After having a good heatsink with a strong fan (yes, silent systems are either water-cooled or stock speeds), that is all you can do. If you can feel a good draw in the lower front and a good push out the back, you are probably ok. Graphics cards are serious heaters these days. The slot fan is necessary, IMO.

Bigger fans are quieter. 120mm are great, but not many ATX cases (cheap ones) are built for those. 90mm is good...not silent, but quieter than 80mm and they move a lot of air.

If you want a serious overclock, then do some reading about overvolting, ramsinks, RAM division ratios (and timings) and general stability issues associated with high overclocks, as well as the tell-tale signs (computer behavior, not flames) that something may be running too high.

Please read more about this...especially with the CoreDuo CPUs. Maybe there is more involved, though I can't imagine what, I am a bit out of the loop. It's all about getting rid of heat. If you overvolt, you create more heat so you will need more cooling. This means perhaps more noise.

My system used to sound like a helicopter. My wife threatened to leave. I moved it into the spare bedroom. She packed. I clocked it down a bit, got bigger fans and created more efficient airflow. All is well. Still a bit loud (2.8 @ 3.5, Zalman cooler, higher spec RAM @ 1:1 with the tightest timings), but it runs pretty fast. A higher FSB gives a pronounced performance hit. A 2.8 @ 3.2 will be faster than a 3.2 @ stock.

Ok...losing continuity...time to finish. Read Thunndarr's link and Google some more.
