Znižovanie násobiča pri celerone 420

[leo]

Ahojte. Zaujímalo by ma , či celeron M 420 (1,6 GHz, 533 FSB) osadený na čipovej sade 940 GML znižuje svoju frekvenciu podľa vyťaženia? Ide konkrétne o notebook Acer Aspire 3692. Viem, že staršie celerony túto možnosť nemali, ale tieto novšie by už mohli. Sú odvodené z Yonahu? Píšte prosím, len ak to viete určite. Vďaka.

Ne, žádný Celeron tuhle funkci nemá, ani ty novější

Nebo z wikipedie:

Celeron M

Banias-512

This Celeron (sold under the Celeron M brand) is based on the Banias Pentium M, and differs from its parent in that it has half the L2 cache, and does not support the clock-varying SpeedStep technology. It performs reasonably well compared to the Pentium M, but battery life is noticeably shorter on a Celeron M–based notebook than it is on a comparable Pentium M notebook.

A system based on the Celeron M processor may not use the Centrino brand name, regardless of what chipset and Wi-Fi components are used.

In Intel's "Family/Model/Stepping" scheme, Banias Celeron Ms and Pentium Ms are family 6, model 9 and their Intel product code is 80535.

Shelton

The Shelton core is a Banias core without any L2 cache, and without SpeedStep. It is used in Intel's small form factor D845GVSH motherboard, intended for Asian and South American markets. The processor identifies itself as a "Intel Celeron 1.0B GHz", to differentiate it from the previous Coppermine-128 and "Tualeron" 1.0 GHz processors.

Dothan-1024

A 90 nm Celeron M with half of the L2 cache of the 90 nm Dothan Pentium Ms (twice the L2 cache of the 130nm Celeron Ms, though), and, like its predecessor, lacking SpeedStep.

In Intel's "Family/Model/Stepping" scheme, Dothan Celeron Ms and Pentium Ms are family 6, model 13 and their Intel product code is 80536.

Yonah-1024

The Celeron M 400-series is a 65 nm Celeron M based on the single-core Yonah Core Solo CPU. Like its predecessors in the Celeron M series, this Celeron M has half of the L2 cache (1 MiB) of Core Solo and lacks SpeedStep. This core also brings new features to Celeron M including a faster front side bus (533 MT/s), SSE3 instructions, and support for the XD bit (J series Dothan Celeron Ms also have XD bit).

Merom-1024

The new Celeron M 520 is a single-core 65 nm CPU based on the Merom Core 2 CPU. It has half of the L2 cache (1 MiB) of the low end Core Duo (2 MiB cache) and lacks SpeedStep. It also features EM64T technology and XD-bit support with 533 MHz FSB.
