A mysterious Prescott 2.4A with S-Spec of SL7E8 has surfaced in Japan 2 days ago. It is running at 533Mhz FSB with 1.4V VCore but has no HT Technology. Prescott will take on a new D-0 stepping to replace the current C-0 stepping and D-0 stepping incorporates planned power optimizations to enable speed enhancements therefore overclockability might improve with the new stepping. This Prescott 2.4A SL7E8 is based on the newly revised S-Spec for D-0 Stepping but something else tells us that it might not be the new stepping yet. Read on.
Pentium 4 2.8A GHz : SL7D8 to SL7E2
Pentium 4 2.8E GHz : SL79K to SL7E3
Pentium 4 3.0E GHz : SL79L to SL7E4
Pentium 4 3.2E GHz : SL7B8 to SL7E5

A Japanese overclocker has checked out the overclockability of the Prescott 2.4A stock cooled on ASUS P4C800-Deluxe and Kingston KHX3500 256MB x 2. He managed to hit 3.6Ghz at default VCore of 1.4V and ~4Ghz at 1.65V.
Next the Prescott 2.4A was LN2 cooled with VCore at 1.75V and overclocked to 4.4Ghz with SuperPI 1M calculation completed in 29s. The CrystalCPUID screenshot revealed something interesting. While the S-Spec of SL7E8 confirms that the Prescott 2.4A is a D-0 stepping but the CPUID shows that it is still a C-0 stepping. D-0 stepping should have a CPUID of 0F34h instead of 0F33h therefore this Prescott 2.4A is still a C0.
It is definitely interesting to see how much better a D0 Prescott can be overclocked. In the next quarter, it will be a battle between LGA775 D-0 stepping Prescott against 939-pin Athlon 64 "Newcastle" CG revisions.

Pentium 2.4A SL7E8, dos novos steppings D0 dos Prescott.
Funciona com um FSB de 533MHz, 1.4v vcore e não tem HyperThreading, logo é um cpu budget...
Pelo que podem ver no quote ,estes cpus estão a dar todos 3,6Ghz default Vcore e com uma subida minima de vcore dão 4Ghz, isto tudo a Ar como é óbvio.
Dima, consegues arranjar destes cpu's ? E caso consigas, a que preço ?
