I was wondering: What is the most overclockable processor, in terms of % increase and highest stable clock speed? Obviously, most people would just say Core 2 Duo, but which one?

My vote is for the 805-D. 2.66 to 3.8 GHZ. on air is routine on a 965/975 chipset. 4.0 is very reachable.

I agree about the 805D, I am running mine at 2.9GHz on air but it does run very hot at 65c idle compared to my X2 4800 bumped up from 2.5 to 2.9GHz on air at 40c under full load!

There are many highly overclockable CPUs out there now. I am not sure where you could find a list of averages. It would be a very interesting list though. :wink:

What about the Celeron D 356? It costs $40 but can be OCd to 4.5ghz on air and 5ghz on water! Even more extreme overclocking than my friends 3.7ghz PD805 on ACF7P

But the best to include performance is I think the E4300. At $125 that some pretty good banging for the buck.
Ah, very true but I got my X2 4800+ and Motherboard for only $139 and I am very pleased with the performance. I have no personal experience with the new C2Ds so I was just answering from my own experience.

celeron 300 mhz to 450 mhz, that was awesome
it had hust 128 cache compared to pentium 2 450mhz which had 512, but the celeron cache was on die, it blew away the pentium and it was really cheap.

The highest I see stable I have gotten is with this processor, the C2D E6400. It's 2.1Ghz I think (never have run it that speed 8O ), but is completely stable at 3.6Ghz, it will run 3.7Ghz and benchmark 3dMark06 but when I run stress test Orthos %100 both cores it throws errors after a awhile. No errors at 3.6Ghz, so it stays there. Whats that like, 80% OC?

Whats more amazing is the FSB which is normally 1056 is running 1800Mhz, way ahead of the 1333 for the upcoming Penryn models.

Which one?
E4300 of course.

It has the lowest base speed and is manufactured via the same basic process as Cores running over 60% faster default speeds.

The 1.8Ghz E4300 can often hit 3.6Ghz on Air for a 100% performance increase.

Not saying I would RECOMMEND running this CPU at those speeds or any CPU at it's MAX stable OC'd speed for long but it can be done.

The high temps and high voltages required generally outweigh the performance gains for the last few Mhz.

I personally vote for the E6420 witch is the same as E6400 but with the extra cache


I have OC mine up to 3.4 on air stable but just to get a kick out of it. Im running at 3.0ghz right now an im very impressed with the performance deference it cost me 200dlls and im running it faster than a 600dlls CPU (E6700) and getting better performance i have seen benchmarks of it toping the Quad core models at just 2.88ghz so i know im there at 3.0ghz and getting very nice temp to 18-27 idle and no more than 34 at load

I know the cache deference is not much of a deference in gaming but i use a lot Word and I know im getting a performance gain of the memory there

I don't think the E6420 would have the highest % since it starts higher and would need to go higher.

That being said, I have seen some tests showing that the E6420 consumes less power than many of the other C2Ds. Not sure why, but that goes along the lines of what you are seeing.

The E6420 is definately a chip of worthy consideration.
I would still likely go for the E4300.

Like you I OC'd to beyond 3.0Ghz but rolled back to 3.0 because the added power was not really needed.

As a result we would likely not see many performance differences to account for the cost difference, especially since I'm still not even close to going into top gear.

All the same the xtra cache is nice and if more studies confirm a cooler, more efficient chip I may just go for that one. I'm a fan of Cool-n-Quiet, especially if I still have all my power.

Actually yes I live close the Beach and it gets pretty cold here I sometimes have to ware a jacket when im playing he he

Sometimes my CPU idles around 18-22C when i play it gets between 25-30 and when its warm it never goes hier than 34C I know its crazzy!!! :lol:

I hade a pentium D 820 those things run hot and i was running it at 30-34 idle and never when t hier than 40C at load

When i saw ppl saying they were running them at 56-65c I on stock speeds I couldn’t believe it I OC that bastard to 3.4ghz and it never went hier than 47C and I thought it was gonna burn 8O

Well what about the processor that produces the highest stable clock speed or fastest processing power? I would think it'd be one of the quad cores but I could be wrong.

I started this thread because I thought it'd be kind of interesting to see which processor would be truly the best bang for teh buck. Also, I recently heard of BOINC which makes use of voluntary computers' cpu power when not in use, to aid to research of stuff like simulations of biology or looking for extra terrestrial life. Also, this method of distributed computing produces lots and lots of processing power, even if still a fraction of the supercomputer Blue Gene's (couple hundred TFLOPS). How many best bang for the buck processors does it take to produce that kind of processing power? And how much does it cost?

I was also thinking that maybe I should overclock my E6300 some more (2.8ghz as of now) to aid their research :p

With the proper board/mem/and cooling just about "any" C2D is a good overclocker really. Thats why they are so popular. Air and Water cooling will get you to 3.4Ghz to 3.7Ghz depending on your chip and setup. If you are interested in extreme overclocking, High Watt TEC (thermalElectric) and phase change cooling will get your 4.5Ghz and higher.

Any app or distributed computing that is multithreaded will do better on multicore systems.

You might look into some speciality processing using Crossfire or Nvidia SLI systems that use the power of the GPUs to process the folding @ home, SETI, etc. These methods can provide up to 1TeraFlop of processing on their own.

That's possible? lol how do I sign up?!! I bet I can overclock my X1900 XT some more too :p

E6400 for me...2.13 to 3.68. 58% +1550 ghz. Stable too. That was on the Ultra-120. Haven't tried the Swiftech water cooler.
