Hi, I have a PC built by "Advent", a UK computer group that manufacturs systems for the most popular retailers. It currently has an Intel Pentium 4 560 3.6Ghz 1MB L2 cache CPU, which I am looking to upgrade to a 660 with a 2MB L2 cache. Sounds simple enough. However, the 660 has "EM64T", and I quote from Intel:
"Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS."

I'm not even bothered about 64-bit, just the L2 cache, but according to this, I need a BIOS and chipset enabled for EM64T just to use the CPU! Sooooo, how do I check/update my BIOS and chipset for EM64T?

According to SiS Sandra:
Mainboard
Manufacturer: Freeline (about which I can find practically no information)
MPS Version: 1.40
Model: Freeline Series
Version: 1.0
System BIOS: 03/16/2005-Grantsdale-6A79DM4GC-00
Chipset: Intel 915G/GV (Grantsdale)

BIOS
Manufacturer: Phoenix Technologies Ltd
Version: 6.00 PG

Thanks!

This is from the intel website.

Intel EM64T represents a natural addition to Intel's computing architecture, allowing platforms to access larger amounts of memory. Processors with Intel EM64T support 64-bit capable operating systems from Microsoft, Red Hat and SuSE. Processors running in legacy mode remain fully compatible with today's existing 32-bit applications and operating systems.

Freeline motherboards are made by trigem. Hers some information on them.

Then there is this on the intel website for intel 915 chipset motherboards.

Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be available. See www.intel.com/technology/64bitextensions/ for more information including details on which processors support Intel EM64T or consult with your system vendor for more information.

On this webpage about 2/3's the way down you can download a pdf on which processors are EM64T and how to enable it.

Personally i don't see why you would want to upgrade a 3.4 to a 3.6. It just isn't that much of a upgrade to be worth the effort.

Hi, I have already looked on the Intel site, and quoted part of what you did in my original post.... And I am not upgrading from a 3.4 to a 3.6, I am upgrading from a 3.6 1MB L2 cache to a 3.6 2MB L2 cache, which, based on what I have read so far, does actually make a significant difference.
Thanks
