A new world record overclock of the wonderful Allendale chip has been reached. An astonishing 4.5GHz is reached, with 500FSB. This is 150% overclock of the processor. You can click on the image to view the validation link, click it, and join me in my drool.Is it the WR for E4300 ?

I have posted the first CPU-Z validation and overclock of Intel® Core™ 2 Duo E4300 on the web, now I am posting the first Intel® Core™ 2 Duo E4400 CPU-Z validation. This is a great processor for high clockage. You can click on the image to view the CPU-Z validation, and my specs i.e. what RAM, and motherboard is used. Aside from the multi of 10x, it's similar in every aspect with the younger brother Intel® Core™ 2 Duo E4300.
I quickly put this to a crash overclock test, and whipped out the first board I laid my eyes on. It is the Bad Axe 2, and I believe, is a great choice. After a brief testing, I manage to get it stable at 3.5GHz which is a hefty 75% overclock.
I posted yesterday that XbitLabs has reviewed this really nice processor, now AMDTech posted their own review. Both agree on one thing, it is highly overclockable as I have trumpeted earlier last year. Check out AMDTech's take on the the processor...Final Words
Every generation a ridiculously overclockable bargain chip is born, and the Core 2 Duo E4300 is just that chip. Although it's not yet launched, Intel has a true winner on its hands with the E4300. Last year we saw overall desktop performance redefined by the Core 2 lineup, and in 2007 it looks like Intel will begin changing what we've come to expect in the sub-$200 CPU market. What's even more impressive is that in another quarter, the E4300 will drop even further to $133. At these prices you can build a second or third system with some very strong performance, at a very reasonable price tag.
The best part of it all is that the E4300 is a no-compromise core; you end up losing VT support, but all of the performance elements are there. The 800MHz FSB isn't crippling enough to really hinder performance, and the smaller cache is more than acceptable for the vast majority of applications. The Core 2 Duo E4300 is no Celeron; if anything it's a spiritual successor to a long line of attractive, highly overclockable Intel CPUs. It's everything Intel's Pentium D 820 was, but with much higher performance and a much lower power envelope.
At default speeds, the E4300 isn't all that impressive in the grand scheme of things; it's effectively a slightly cheaper, slightly slower E6300. But much like the E6300, much of the appeal of the E4300 comes from overclocking - and overclock it does. Compared to other Core 2 CPUs, the E4300 doesn't set any new overclocking records but at the price it's a true bargain.
The change in base FSB speed also has advantages in overclocking, making it possible to use a linked (1:1 ratio) memory speed and still get extremely high overclocks without resorting to anything more than DDR2-800 memory. The E6300 has a 7x multiplier and a 266 MHz base bus speed, so without dropping to a 4:5 ratio and sticking with DDR2-800, the E6300 tops out at 7x400 or 2.8 GHz. With a 9x multiplier the E4300 can potentially reach as high as 9x400 or 3.6 GHz while keeping memory at or below DDR2-800. While it is possible to get bus speeds of P965 motherboards above 500 MHz, it is far more difficult and often requires more expensive component choices, making the E4300 the new king of budget overclocking. Throw in a more powerful CPU cooling setup, and we have no doubt it will be very easy to exceed our 3.37GHz overclock by a large margin.
At stock speeds, the E4300 ends up offering similar performance to the Athlon 64 X2 4200+. In SYSMark 2004SE, DivX and some games it's faster, and in other situations it's basically the same speed. The Athlon 64 X2 3800+ ends up being slower in every benchmark, but with a lower price it's still a reasonable choice. Obviously the Core 2 upgrade path is a bit more desirable these days than AMD's Socket-AM2 platform, so the E4300 gets the nod there, but you can't really go wrong with either chip at default settings. When overclocked things get a little more complicated, but the E4300 gets the recommendation as a 2.8 - 3.0GHz Athlon 64 still ends up being slower than a 3.38GHz Core 2.
Compared to Intel's other value offerings, mainly the existing Pentium D lineup, the decision is clear. With the E4300 at $163 and moving down to $133 by Q2, cheap no longer means NetBurst. Intel is planning on significantly ramping its dual core presence this year, and with the E4300 available as a part of the lineup we can see exactly how. If you're building a Vista system early this year and want to do it efficiently, Intel is going to make it even cheaper to do.
XBitLabs has finally gotten their hands with the coveted E4300 series of processor which I overclocked at more than 100% (which was 95% overclocked before) and posted early last year even before the world have seen any CPU-Z validation. Check out the review and get ready for the wave of the uber overclockable processor from Chipzilla. Expand for more..Conclusion
The Core 2 Duo E4300 processor has left a positive impression on us. It can become a bestseller thanks to its rather low price - after all, it is the cheapest CPU in the highly appealing Core 2 Duo series.
Performance of the Core 2 Duo E4300 isn't that impressive as that of the senior models of the series. Although it differs by only 3-5% from the Core 2 Duo E6300, the new CPU is slower than the Pentium D 945 and Athlon 64 X2 4200+, which cost about the same money, in some benchmarks. But there are few such benchmarks and the new CPU is far more economical than any of its opponents.
The Core 2 Duo E4300 is also a gift for overclockers since it doesn't require special overclocker-friendly components and has an affordable price. But to all appearances, Allendale-based CPUs won't reach as high frequencies at overclocking as Conroe-based CPUs do.
Earlier today, FUGGER of XtremeSystems, shows benchmark of Conroe's lesser known little sibling, Allendale. Due to the uber low multiplier, even at an extreme FSB on the Intel® D975XBX "Bad Axe" motherboard, clockspeed is limited at 3.22GHz. However, at this speed, it already reaches sub20s SuperPi.Moving up to the B0 stepping and put the Core 2 Dou E6300 1.8Ghz 2MB L2 Cache under the vapo for some FSB testing and to see if the 2MB makes any difference in overclocking.
If my Presler could hit this kind of bus speed it would give the AM2 a brutal beating in bandwidth.
This is the low end chip matching my 2.13Ghz A0 chip in speed and beating it on bus speed. This chip also allows full voltage from the mobo.
